design pressure for PA–11 to allow the
use of a PA–11 piping system at
pressures up to 200 psig. Under the
proposal, the design factor for PA–11
would be raised from 0.32 to 0.40,
which would allow for a greater
operating pressure. The operating
pressure limit for 2-inch diameter pipes
of this material would also be raised
from 100 psig to 200 psig, to allow these
pipe systems to be operated up to the
pressure limit determined by the design
factor.
Arkema asserts that pipelines with the
new PA–11 material will pose less risk
to the public at a design factor of 0.40
than older thermoplastic piping
materials used with a 0.32 design factor
and that allowing an increased design
pressure will allow gas companies to
replace metal piping systems with 2inch plastic pipe operating up to 200
psig to avoid the risk of corrosion failure
in steel pipes. A detailed technical
justification, including performance test
results for PA–11 pipe and a discussion
of its history of use, is provided in the
petition, which may be read in its
entirety in the docket.
With this notice, OPS is seeking
further information and inviting public
comment on the performance of the PA–
11 pipe and a potential increase in the
design factor and the design pressure for
new thermoplastic piping. OPS will
consider Arkema Inc.’s petition, any
comments received by the public, and
other information to determine whether
or not to initiate rulemaking.

SUMMARY: We are proposing to amend
the definition of ‘‘designated seating
position’’ in the Federal motor vehicle
safety standards (FMVSSs), and to
establish a new procedure for
determining the number of designated
seating positions on bench and split
bench seats. This document also
proposes to apply that procedure to all
types of vehicles, regardless of weight,
and eliminate the existing exclusion for
temporary or folding jump seats. The
proposed rule would also revise test
procedures for seat belt anchorage
requirements so that they are suitable
for side-facing, temporary or folding
jump seats. NHTSA’s goal in proposing
these amendments is to improve the
objectivity of the ‘‘designated seating
position’’ definition and thereby
facilitate efforts of the agency to ensure
that the number of designated seating
positions and occupant restraint
systems in a vehicle is representative of
real world occupancy.
The proposed rule would also revise
the general incorporation by reference
provision for the FMVSSs by providing
a centralized index of all matters therein
incorporated by reference.

I. Background
Motor vehicle manufacturers are
required to designate which locations in
their vehicles are seating positions. The
designation of a location as a seating
position is important for a variety of
reasons. For example, passenger cars are
required, under Federal Motor Vehicle
Safety Standard (FMVSS) No. 110, Tire
and rim selection, to be clearly labeled
with a maximum seating capacity.
Moreover, FMVSS No. 208, Occupant
crash protection, requires that each
designated seating position, as defined
in 49 CFR 571.3, in a light vehicle 1 be
provided with the appropriate occupant
crash protection system (e.g., air bag,
safety belts or both). If a vehicle has
fewer designated seating positions than
1 NHTSA
uses the term ‘‘light vehicle’’ to refer to
passenger cars, multipurpose passenger vehicles,
trucks and buses with a gross vehicle weight rating
(GVWR) of not greater than 10,000 lb.
VerDate jul<14>2003
16:16 Jun 21, 2005
Jkt 205001
the number of seated individuals
actually occupying it, some occupants
would not be protected by safety belts
or other crash protection systems.
In 1978, the agency expressed concern
with the common practice of
designating front seats as having two
seating positions, although they had
capacity to accommodate three adults
(43 FR 21892; May 22, 1978; Docket No.
78–13). As a result of this practice, front
center passengers were not provided
with safety belt assemblies. In response
to this concern, the agency amended the
definition of ‘‘designated seating
position’’ to specify dimensional
parameters. The agency stated that this
was ‘‘intended to ensure that all
positions likely to be used for seating
will be equipped with occupant
restraint systems’’ (44 FR 23229; April
19, 1979). The portion of the definition
of ‘‘designated seating position’’
relevant to the above discussion remains
unchanged today.2
As discussed below, however, field
data regarding vehicle occupancy
indicates that there is some ambiguity in
the current definition and that it might
not always require what we believe
should be a full complement of
designated seating positions (DSPs) to
accommodate real world use.
II. Safety Problem
Vehicle seat design and motor vehicle
crash data indicate that in some
instances real world occupancy rates
exceed the number of designated seating
positions in a vehicle, particularly on
bench and split seats. The agency has
placed a Preliminary Regulatory
Evaluation (PRE) in the docket for this
rulemaking that details our findings.
Within the report, a survey of vehicle
crash and fatality reporting systems data
indicates that three passengers are
occupying seats designated as having
two seating positions (2–DSP seats). The
agency reviewed and compared
incidents involving three passengers
occupying either a 2–DSP rear seat or a
rear seat with three designated seating
positions (3–DSP seat).
Additionally, the PRE shows a
significant decrease in the belt usage
rate when comparing incidents in which
two passengers occupied a 2–DSP seat
to incidents in which three passengers
occupied a 2–DSP seat. The 1997 to
2001 National Automotive Sampling
System (NASS) data indicated a drop in
the belt usage rate for these cases from
53.25 percent to 27.67 percent,
2 The definition was amended again in 1995 to
allow each wheelchair position to count as four
designated seating positions for the purpose of
determining vehicle classification in school buses
only (57 FR 15504; March 24, 1995).
PO 00000

36095
respectively. These FARS data indicate
that an occupant is at higher risk when
he or she is one of the three occupants
in a rear 2–DSP seat than when in a 3–
DSP seat. These risks appear to be
independent of vehicle size and the
presence of padded or carpeted barriers
that are intended to limit capacity.
Vehicle size may not adequately limit
the number of passengers occupying a
vehicle seat from exceeding the
designated capacity. The fatality rate for
a passenger occupying a rear 2–DSP seat
together with two other passengers was
only slightly lower for occupants in a
Geo Metro, a sub-compact, than the
average rate for occupants of all vehicles
surveyed: 6.02 versus 6.07 fatalities per
one million registered vehicles.
The rate at which one of the three
passengers occupying a 2–DSP seat is
killed in a motor vehicle crash also
appears to be independent of the
presence of physical features, other than
those discussed in the next paragraph,
intended to limit occupancy. The
Chevrolet Camaro, which features a
carpeted drive shaft tunnel that
separates the two rear designated
seating positions, had a similar fatality
rate to that of the Ford Mustang. While
the Camaro has a carpeted barrier, the
Ford Mustang has a rear bench seat with
no barrier between the two designated
seating positions. The fatality rate for
instances of three passengers occupying
a 2–DSP seat was actually slightly
higher for the Camaro than for the
Mustang; 7.81 versus 7.51 fatalities per
one million registered vehicles,
respectively.
Conversely, available data
demonstrate that certain physical
obstructions in the second row of
seating can effectively limit the number
of occupants to the number of
designated seating positions. The Saturn
SC Coupe 2 Door had no FARS fatalities
involving three occupants in its 2–DSP
second row of seating, and the Acura
Integra 2 Door had only 2.44 such
fatalities per one million registered
vehicles. Both the Saturn SC Coupe and
the Acura Integra had a hard plastic
console that divides the rear seat into
two seating positions, limiting seating
capacity.
In cases in which the same vehicle
model was manufactured in both a twodoor (2–DSP second row seating) and a
four-door (3–DSP second row seating)
version, the PRE shows that the incident
rate for occupants of the rear seat of the
two door version, when occupied by
three passengers, was two-thirds of that
of the four-door version, or higher.
While the incident rates may not
directly correlate to the frequency of
three occupants using a 2–DSP seat, the
E:\FR\FM\22JNP1.SGM
22JNP1
36096
Federal Register / Vol. 70, No. 119 / Wednesday, June 22, 2005 / Proposed Rules
rates demonstrate that seats designated
as having only two seating positions are
being used by three occupants. As a
result, at least one occupant would not
have access to a safety belt assembly. A
survey of State Data System (SDS)
accident reports compared the two-door
(with 2–DSP second row seating) and
the four-door (with 3–DSP second row
seating) models of the Ford Explorer
and the Chevrolet S10 Blazer. The
incident rate for second row occupants
when three passengers occupied the
second row of the two-door Ford was
approximately 64 percent of that of the
four-door model. For the Chevrolet
models, incidents involving three
passengers occupying the second row
seat for the two-door model occurred at
a rate of 78 percent of that of the fourdoor model.
III. Proposed Amendments
The agency is proposing to amend the
definition of ‘‘designated seating
position’’ to better ensure that seating
position designations more accurately
reflect real world occupancy. The
proposed amendment would define
‘‘designated seating position’’ based on
available hip room as measured
according to procedures established by
the Society of Automotive Engineers
(SAE), with qualifications to provide for
measurement of the largest hip room
dimension and the incorporation of Hpoint in the measurement procedure.
We are also proposing a formula to
determine the appropriate number of
designated seating positions on bench
and split bench seats according to the
hip room measurement. The formula
proposed in this document would
further clarify the appropriate number
of designated seating positions for a
vehicle seat.
We note that while the agency was
already working internally to address
the safety concerns discussed above, we
received a petition for rulemaking from
Strategic Safety requesting that the
agency establish a more objective
method for determining the number of
designated seating positions (September
10, 2002; Docket No. NHTSA–2002–
11398–7). Since the agency had already
initiated work on the issue raised by
Strategic Safety, we view its petition as
moot.
A. ‘‘Designated seating position’’
If made final, today’s proposal would
establish a definition of ‘‘designated
seating position’’ that is more reflective
of the occupancy rates experienced in
the real world. By expressly relying on
a hip room measurement for a 5th
percentile adult female, instead of the
somewhat less precise and less certain
VerDate jul<14>2003
16:16 Jun 21, 2005
Jkt 205001
criteria of being large enough to
accommodate such a person, the
definition would provide for more
objective determinations of what is a
‘‘designated seating position.’’
We are also making the definition
more objective by proposing to remove
language that relies on the likelihood
that a location will be used as a seat
while a vehicle is in motion. Currently,
a designated seat position is defined, in
part, as:
[Any] plan view location capable of
accommodating a person at least as large as
a 5th percentile adult female, if the overall
seat configuration and design and vehicle
design is such that the position is likely to
be used as a seating position while the
vehicle is in motion [.]
As evidenced by the current vehicle
fleet experience, we believe that the
‘‘likely to be used’’ language does not
provide adequate objectivity to
determine when a vehicle seat
designation is required. This difficulty
leads to a safety concern when the
number of seating positions designated
for a seat differs from the real world
occupancy of that seat. Therefore, we
are proposing to replace the ‘‘likely to
be used’’ language and incorporate the
term ‘‘seat,’’ into the definition.
In relying on the term ‘‘seat,’’ we
recognize that it is not practicable to
design a vehicle to prevent all potential
occupant misuse of interior positions.
However, we believe there is abundant
notice to drivers and occupants of light
vehicles that the use of safety belts is
essential, and therefore, that sitting in a
location in a vehicle that is not
equipped with a safety belt is
inappropriate and dangerous. Vehicle
literature and advertising, as well as
numerous public outreach programs,
inform and remind the public of the
need to wear safety belts while riding in
a vehicle. Vehicle owner’s manuals are
replete with exhortations on the
importance of always wearing a safety
belt. Further, the warning label required
to be on the visor in every light vehicle
expressly tells vehicle occupants to
wear safety belts always. The public’s
awareness of these messages is
evidenced by the fact that the national
safety belt use rate increased from 71
percent in 2001 to 80 percent in 2004,
an all time high.
Consistent with the current definition,
the proposed definition would be based
on accommodating a 5th percentile
adult female.3 However, unlike the
3 In examining the fatalities that occurred when
a seat was occupied by more occupants than there
were occupant protection systems, we found no
definite skew toward child fatalities from the age
distribution in the FARS data that would indicate
PO 00000
Frm 00042
Fmt 4702
Sfmt 4702
current definition, the proposed
definition would expressly and
exclusively rely on a hip room
measurement. A designated seating
position would be any seating location
that has at least 330 mm (13 inches) of
hip room,4 when measured according to
the procedure described below.
B. Measuring Hip Room
NHTSA is proposing to establish a
revised procedure for measuring hip
room and to place it in a new section,
§ 571.10, Designation of seating
positions. Section 571.10 would set out,
with several modifications, the
procedure in SAE Recommended
Practice J1100 rev. February 2001,
‘‘Motor Vehicle Dimensions,’’ for
measuring hip room. Under SAE J1100
rev. February 2001, hip room of a seat
is the minimum dimension measured
laterally between the interior trim 5 of a
vehicle on the ‘‘X’’ plane through the
seating reference point (SgRP) within 25
mm (1 inch) below, and 76 mm (3
inches) above the SgRP and 76 mm (3
inches) fore and aft of the SgRP.
However, under the proposal, we would
use the H-point as a reference as
opposed to the SgRP. SgRP is a design
point designated by a manufacturer,
while the H-point is determined by
measurements within the vehicle.
Reliance on the H-point would permit
making measurements across an array of
seat positions, independent of a
manufacturer’s designation.
While the SAE procedure uses the
minimum dimension measured laterally
between interior trim of a vehicle on the
‘‘X’’ plane through the seating reference
point, the agency is proposing to use the
maximum dimension. Further, in the
case of adjustable seats, the proposal
would use the position that produces
the maximum value. These two aspects
of the proposal would result in the
largest realistic hip room being
measured, and thus would more
accurately account for all potential
seating. Further, the width of a seat
would include any void between the
seat and the adjacent interior trim or
adjacent seat unless the void meets
certain dimensional criteria.
Hip room would be considered to be
continuous under § 571.10, unless there
is a separation greater than 150 mm (5.9
a need to consider basing the definition on younger,
smaller occupants.
4 The 5th percentile female hip width specified in
S7.1.4 of FMVSS No. 208 is of 325 mm (12.8
inches). We rounded the measurement to 330 mm
(13 inches) for purposes of the formula proposed
below.
5 Interior trim is a molded plastic, fabric or other
non-supportive surface within the occupant
compartment (e.g., a molded arm rest, a carpeted
door panel, etc.).
E:\FR\FM\22JNP1.SGM
22JNP1
Federal Register / Vol. 70, No. 119 / Wednesday, June 22, 2005 / Proposed Rules
inches) between adjacent seat cushions,
or between a seat cushion and the
vehicle interior, and the separation
contains either:
(1) A fixed, unpadded impediment
that is at least 5 mm (0.2 inches) higher
than the highest point on the upper
surface of the seat cushion when viewed
in profile, which extends for greater
than two-thirds of the horizontal depth
of the seat cushions;6
(2) A void that can accommodate a
rectangular box 150 mm (5.9 inches)
wide, 150 mm (5.9 inches) high, and
two-thirds of the horizontal depth of the
seat cushion in length, with the box
sitting 2 mm (0.08 inches) below each
point on the top profile of the seat
cushion 7; or
(3) A parking brake or gear shift
handle, that when placed in the lowest
possible position, is at least 25 mm (1.0
inches) higher than the highest point of
the seat cushion.
These criteria are based on the
designs observed in the FARS study and
noted in the PRE, which demonstrated
that impediments such as carpeted
barriers are ineffective at preventing
three people from sitting on a seat with
only two designated seating positions.
The agency requests comments on
whether these specifications would
result in seat designations more
reflective of real world occupancy rates.
C. Number of Designated Seating
Positions
Section 571.10 would also provide
equations for use in determining the
number of ‘‘designated seating
positions’’ on a seat. The proposed
equations for calculating the number of
designated seating positions would be
dependent upon the overall continuous
hip room. For seats with less than 1400
mm (55 inches) of hip room, the
measured hip room would be divided
by 4008 and rounded to the nearest
whole number to produce the number of
designated seating positions. For
example, seats with approximately 1007
mm (39.5 inches) of hip room would be
designated as having three seating
positions.9
Based on the vehicles surveyed in the
PRE, at a seat width of 1007 mm (39.5
6 A surface covered in carpet or other padding
would not meet this condition. This is in response
to the FARS incident data that showed the carpeted
drive shaft tunnel failed to act as an impediment.
7 See Figure 1 of the proposed regulatory text.
8 Other international standards use a similar
number to determine the number of seating
positions; i.e., Australian Design Rule 5, Section 10;
Automobile Type Approval Handbook for Japanese
Certification, Section 11–1, Article 22.
9 1007 mm of measured hip room divided by 400
equals 2.5, which would then be rounded up to
three.

inches) and more, three occupants were
more likely to occupy a 2–DSP seat,
unless a non-padded barrier was
present. Requiring seats at least this
width or wider to be designated as
having three seating positions would
present manufacturers several options
for compliance. Manufacturers could
comply by redesigning their seats to
include the appropriate impediment,
provide the necessary void between
adjacent seat cushions, or by installing
an additional seat belt assembly. We
anticipate that manufacturers would be
more likely to redesign such seats, if
needed, to incorporate an impediment
or void as necessary. The potential
vehicle packaging and marketing issues
associated with the addition of a seat
belt assembly, along with compliance
implications (e.g., dynamic crash
testing, cargo capacity, etc.) would make
this option unlikely. Additionally,
issues of comfort might arise as a result
of three occupants being seated at the
location. Space limitations may make it
difficult for occupants to use their
respective safety belts when three
occupants are seated at such a location.
For seats with 1400 mm (55 inches) or
more of hip room, the measured hip
room would be divided by 450 and
rounded to the nearest whole number.
The purpose of picking 450 as the
divisor is to prevent larger 3–DSP seats
from having to be designated as 4–DSP
seats. The data do not demonstrate a
problem with 3–DSP seats being
occupied by four passengers, and does
not demonstrate the potential for any
benefit from such a requirement. In
addition, for larger vehicles with longer
bench seats (e.g., shuttle buses and
limousines), the 450 divisor results in a
designated seating position width that
aligns with the width typically used by
seating manufacturers. The rationale for
using two different equations is further
discussed in the Benefits and Costs
section.
Under the current definition, any
bench or split bench seat in a passenger
car, truck, or multipurpose passenger
vehicle with a gross vehicle weight
rating (GVWR) less than 4,536 kilograms
(10,000 lb), having greater than 1270
mm (50 inches) of hip room shall not
have less than three designated seating
positions. Under the proposed
definition, the calculation for
determining the number of designated
seating positions on a bench or split seat
would apply to all vehicles equipped
with such seats regardless of the vehicle
weight.
D. H-Point
This document also proposes to
update the definition of ‘‘H-Point,’’
PO 00000
Frm 00043
Fmt 4702
Sfmt 4702
36097
which is referred to in the proposed
definition of ‘‘designated seating
position.’’ The current definition of ‘‘HPoint’’ references the ‘‘H-Point’’
definition in SAE Recommended
Practice J826, ‘‘Devices for use in
Defining and Measuring Vehicle Seating
Accommodation’’ (1962). Since the
establishment of the ‘‘H-point’’
definition in 49 CFR § 571.3, SAE J826
has been updated (revised July 1995)
and now refers to SAE J1100 for
defining ‘‘H-Point.’’ This rulemaking
proposes to reference SAE J1100
directly in defining ‘‘H-point.’’ While
SAE J826 has been updated, there has
been no significant change to the
definition of ‘‘H-Point.’’ Further, the
proposed ‘‘H-point’’ definition would
specify that the H-point is to be
determined using the 3–D test fixture.
E. Auxiliary Seating and Safety Belt
Anchorages
We are proposing to include auxiliary
seats and jump seats in the definition of
‘‘designated seating position.’’
Currently, the definition does not
include these seats. Since these seats are
not designated seating positions, they
are not subject to the occupant crash
protection requirements applicable to
designated seating positions (e.g., safety
belt requirements).
Presently, the agency urges that all
occupants in light vehicles be
appropriately restrained when a motor
vehicle is in operation. When the
agency originally adopted the
designated seating position definition,
safety belt use rates were well below 20
percent and the focus of the agency was
not on temporary seats. Now that safety
belt use rates are much higher, the
agency is focused on all occupants being
properly restrained. This includes those
occupants on auxiliary seats.
If the proposed definition is adopted,
auxiliary seats and folding jump seats
would be required to meet all
requirements in FMVSSs applicable to
designated seating positions, including
the requirements of FMVSS No. 210,
Seat belt assembly anchorages.
Traditionally, manufacturers have
classified some side-facing seats in light
vehicles as auxiliary or jump seats. The
current test procedures for the
anchorage strength requirements as
specified in S5.2 of FMVSS No. 210
were designed for forward and rear
facing seats only. Under S5.2, a force
must be applied in the direction in
which the seat faces in a plane parallel
to the longitudinal centerline of the
vehicle. For side-facing seats, including
auxiliary or jump seats, the direction
that the seat faces is perpendicular to
the longitudinal centerline of the
E:\FR\FM\22JNP1.SGM

Federal Register / Vol. 70, No. 119 / Wednesday, June 22, 2005 / Proposed Rules
vehicle. Consequently, a force cannot be
applied simultaneously in the direction
that a side-facing seat faces and in a
plane parallel to the longitudinal
centerline of the vehicle. To permit
strength testing of seat belt anchorages
at side-facing designated seating
positions, we are proposing to amend S5
of FMVSS No. 210 to specify that for
side-facing seats, the specified force
would be applied in the direction that
the seat faces in a vertical plane
perpendicular to the longitudinal
centerline of the vehicle.
F. Preemption
Under 49 U.S.C. 30103(b), when a
safety standard is in effect under the
FMVSSs, a State is preempted from
adopting or retaining a standard that
imposes a different standard of
performance, except for vehicles
obtained for its own use. This express
preemption clause has been interpreted
as limited to State statutes and
regulations based on the presence in the
Safety Act of a provision stating that
compliance with a FMVSS does not
exempt ‘‘any person from any liability
under common law’’ (49 U.S.C.
30103(c); ‘‘saving clause’’).10 However,
neither the express preemption clause
(by negative implication) nor the saving
clause bars the preemption of state
common law in instances in which state
law (tort law) conflicts with uniform
Federal safety regulations of national
applicability.11
The definition of ‘‘designated seating
position’’ would be established in the
section for common definitions for the
FMVSSs to accomplish NHTSA’s
essential safety objectives. As described
below, differing definitions would not
provide the important safety benefits
that NHTSA envisions and could
instead be detrimental to safety. Hence,
any differing requirements would
‘‘prevent or frustrate the
accomplishment of a federal objective.’’
Crosby v. National Foreign Trade
Council, 530 U.S. 363 (2000). Therefore,
if the proposed definition of
‘‘designated seating position’’ would be
made final, section 30103(b) would
preempt State statutes and regulations
requiring the designation of more or
different seating positions than those
required by that definition.
10 Geier v. American Honda Motor Co., Inc., 529
U.S. 861 (2000).
11 ‘‘[T]he saving clause (like the express preemption provision) does not bar the ordinary
working of conflict pre-emption principles.’’ Geier
v. American Honda Motor Co., Inc., 529 U.S. 861,
869, emphasis original. Indeed, though we are
setting forth the agency’s intention in this particular
matter, ‘‘the failure of the Federal Register to
address pre-emption explicitly is thus not
determinative. Id. at 884.
VerDate jul<14>2003
16:16 Jun 21, 2005
Jkt 205001
In addition, if made final, this
definition of ‘‘designated seating
position’’ would preempt any
conflicting determinations in state tort
law as to whether a location is or ought
to be a designated seating position. A
tort law determination premised on the
designation of more designated seating
positions than those required by the
proposed definition could have a
negative safety impact. Such a
determination could result in a location
being equipped with a greater number of
safety belts than required under the
Federal standards. The installation of an
excessive number of safety belts might
decrease, not increase, safety. Seat belt
comfort and convenience are important
factors affecting the level of safety belt
use. Occupants might be less likely to
use safety belts because limited space
would make such use difficult or
uncomfortable (i.e., if too many safety
belts were installed at a location, some
occupants may end up sitting on
buckles or be prevented from reaching
his or her respective belt by the
presence of another occupant). The
potential for such a scenario would
frustrate the efforts of this agency to
base the number of designated seating
positions, and thus the number of safety
belts, on reasonably anticipated
occupancy levels. This would hamper
our efforts to promote increased safety
belt use rates.
IV. Benefits and Costs
The agency has tentatively
determined that there are three ways for
manufacturers to address the proposed
amendment to DSP: Add a lap/shoulder
belt; create a space between the seats to
restrict the number of seating positions;
and design an impediment to reduce the
likelihood of people sitting in between
the outboard seats. If manufacturers
were to add additional lap/shoulder
belts, 5 lives would be saved and 41
AIS 12 2–5 injuries would be prevented
annually once the proposal is fully
implemented. We believe the other two
options would provide somewhat less
benefit than supplying a lap/shoulder
belt, although we are unable to quantify
the benefits of an impediment and void
because the benefits are influenced by
occupant behavior. The cost of the
proposed change in the DSP definition
would depend on which options
manufacturers implemented, ranging
from approximately $12 million to $41.7
million.
12 The AIS or Abbreviated Injury Scale is used to
rank injuries by level of severity. An AIS 1 injury
is a minor one, while an AIS 6 injury is one that
is currently untreatable and fatal.

Fmt 4702
Sfmt 4702
The proposed inclusion of side-facing
seats, jump seats, and auxiliary seats in
the definition of designated seating
position is not reflected in the benefit
and cost analysis. The agency is
unaware of any current vehicles with
side-facing, jump seats, or auxiliary
seats that would not already comply
with this proposal, if it were made final.
Benefits
To estimate the number of lives saved
and injuries that would be prevented if
manufacturers chose to add safety belts,
the agency relied on belt use rates, the
estimated effectiveness of rear lap/
shoulder belts, and the potential injuries
and fatalities to unbelted rear seat
occupants. Based on these estimates, the
agency has tentatively determined that 5
lives would be saved, and 41 AIS 2–5
injuries would be prevented, annually.
To estimate seat belt usage, the agency
relied on an adjusted average of the rear
seat left, middle, and right positions
derived from seat belt use rates
generated by the General Estimates
System (GES) and National Occupant
Protection Use Survey (NOPUS).13
Because GES data rely on reporting from
vehicle occupants, it may overstate seat
belt use. To correct for this, the agency
divided the GES estimates by the seat
belt use rate observed in the June 2002
NOPUS study to obtain a conservative
usage rate.14 This adjusted factor was
then applied to an average of seat belt
use rates for the rear left, rear middle,
and rear right seat positions to generate
a seat belt use rate of 64.6 percent for
passenger cars and 64.1 percent for light
trucks and vans (LTVs).
Based on previous studies, the agency
has estimated the effectiveness of lap/
shoulder belts in the rear seat of
passenger cars and LTVs as follows:

13 Data for GES come from a nationally
representative sample of police reported motor
vehicle crashes of all types, from minor to fatal and
relies in part on statements made by vehicle
occupants. NOPUS data is generated through direct
observation of occupant behavior.
14 Because NOPUS is based on direct observation
of occupant behavior as opposed to occupant
reporting, the seat belt use rate is less likely to be
overstated.

multipurpose passenger vehicles or
buses with a GVWR less than 4,356
kilograms (10,000 pounds) to have seat
belt assemblies for each designated
seating position. The agency recently
published a final rule requiring lap/
shoulder belt assemblies in the rear
center designated seating positions (69
FR 70904; December 8, 2004; Docket No.
NHTSA–04–18726; Notice 1). Therefore,
it used the cost of the lap/shoulder belt
assembly in that rulemaking to estimate
the cost of this compliance option.
For this analysis, the agency relied on
an estimated average cost of installing a
lap/shoulder belt in the rear center seat
of $29.85.15 For LTVs, the agency
expects the rear center seat belt costs to
be similar to those of passenger cars.
Again, using the model year 2003 sales
figure, we estimate that the cost for
installing lap/shoulder belts in the rear
center seats of vehicles with an
increased number of designated seating
positions would be approximately
$30.74 million (1.03 million vehicles ×
$29.85).
For some vehicles, the addition of a
seat belt assembly to the rear center seat
would also require reinforcement of the
seat to accommodate an anchorage for
the shoulder portion of a lap/shoulder
seat belt assembly. The rear seat of
passenger cars and pick up trucks
would not need to be reinforced because
the anchors for the shoulder belt could
be attached to the back package shelf or
down to the floor frame of the vehicle
without impinging on the floor space or
trunk space. However, this would not be
the case for passenger vans and sport
utility vehicles (SUVs). In those
instances, the floor space where an
anchorage may be required would be
located in occupant or cargo space.
Therefore, the anchorage would need to
be attached to the seat itself and the seat
would need to be reinforced. This
reinforcement would cost $32.79
($2003) per seating position. The agency
estimates that 337,76116 vehicles would
need to reinforce the rear seat to
accommodate an additional seat belt
assembly. The total cost of
strengthening the rear seats of passenger
vans and SUVs to accommodate the
shoulder portion of the lap/shoulder
belt would be $11.08 million ($32.79 ×
337,761 vehicles). This would bring the
total cost for adding lap/shoulder belts

position from 2–DSP to 3–DSP to $41.7
million ($2003).
As previously stated, the proposed
equation for calculating the number of
designated seating positions varies
depending on overall hip room; for seats
with less than 1400 mm of hip room, the
hip room is divided by 400, while a hip
room measurement of anything equal to
greater than 1400 mm would be divided
by 450. If we used a divisor of 400 for
all seats, regardless of width, a seat with
1400 mm of hip room would increase
from 3–DSP under the existing
definition in section 571.3 to a 4–DSP
seat. Benefits for such a redesignation
would be minimal because the rate at
which four persons occupy a seat
location currently designated as a 3–
DSP seat is low. Further, the number of
LTVs that would need to be modified
would increase by approximately 3.4
times, resulting in cost range of $40.53
million to $217.6 million.
V. Incorporation by Reference
Under 1 CFR part 51, Incorporation by
Reference, the agency must declare that
the Director of the Federal Register has
approved incorporation by reference of
a publication into a regulation. If made
final, this proposal would amend the
general incorporation by reference
provision at § 571.5, Matters
incorporated by reference, to include a
centralized index of all of the
publications incorporated into part 571.
VI. Effective Date
If adopted, the amendments proposed
in this rulemaking action would become
effective on the third September 1st
after the date of publication of a final
rule in the Federal Register. For
example, if a final rule were adopted on
December 1, 2005, the rule would be
effective beginning September 1, 2008.
As stated above, we anticipate that
manufacturers would incorporate a void
or barrier in 2–DSP vehicle seats that, as
currently configured, would become
classified as having three designated
seating positions. This would require
less redesign than equipping these seats
with an additional seat belt assembly.
Based on this assumption, we have
tentatively concluded that a minimum
of two years would be adequate time for
manufacturers to make any necessary
changes. We request comment on this
tentative conclusion.

VIII. Rulemaking Analyses and Notices
A. Executive Order 12866 and DOT
Regulatory Policies and Procedures
Executive Order 12866, ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993), provides for making
determinations whether a regulatory
action is ‘‘significant’’ and therefore
subject to Office of Management and
Budget (OMB) review and to the
requirements of the Executive Order.
The Order defines a ‘‘significant
regulatory action’’ as one that is likely
to result in a rule that may:
(1) Have an annual effect on the
economy of $100 million or more or
adversely affect in a material way the
economy, a sector of the economy,
productivity, competition, jobs, the
environment, public health or safety, or
State, local, or Tribal governments or
communities;
(2) Create a serious inconsistency or
otherwise interfere with an action taken
or planned by another agency;
(3) Materially alter the budget impact
of entitlements, grants, user fees, or loan
programs or the rights and obligations of
recipients thereof; or
(4) Raise novel legal or policy issues
arising out of legal mandates, the
President’s priorities, or the principles
set forth in the Executive Order.
This document proposes to amend the
definition of designated seating position
in 49 CFR 571.3. The proposed
amendment would provide an objective
procedure for determining the number
of designated seating positions present
in a vehicle, and provide manufacturers
with a more objective method for
delineating designated seating positions.
Under the proposed definition,
manufacturers could maintain a
vehicle’s current number of designated
seating positions by incorporating
design changes at a cost of $11.97
million. By way of example, the Subaru
Baja is currently equipped with a barrier
that would maintain a 2–DSP
designation for the second row seat
under the proposed amendment.
Further, several previous vehicle
models, e.g., the Saturn SC Coupe and
Acura Integra 2-door, were similarly
equipped.
This rulemaking document was not
reviewed by the Office of Management
and Budget under E.O. 12866. It is not
considered to be significant under E.O.
12866 or the Department’s Regulatory
Policies and Procedures (44 FR 11034;
February 26, 1979). The agency has
prepared a regulatory evaluation as
required by the DOT policies and

procedures. A copy of that evaluation
has been placed in the docket for this
rulemaking.
B. Regulatory Flexibility Act
In compliance with the Regulatory
Flexibility Act, 5 U.S.C. 601 et seq.,
NHTSA has evaluated the effects of this
proposed action on small entities. I
hereby certify that this notice of
proposed rulemaking would not have a
significant impact on a substantial
number of small entities.
The following is the agency’s
statement providing the factual basis for
the certification (5 U.S.C. 605(b)). If
adopted, the proposal would directly
affect motor vehicle manufacturers and
motor vehicle seat manufacturers.
According to the size standards of the
Small Business Association (at 13 CFR
Part 121.601), the size standard for
manufacturers of ‘‘Automobile
Manufacturing’’ (NAICS Code 336111)
is 1,000 employees or fewer.
Manufacturers of vehicle seats are
considered manufacturers of ‘‘Motor
Vehicle Seating and Interior Trim
Manufacturing’’ (NAICS Code 336360).
The size standard for NAICS Code
336360 is 500 employees or fewer.
The majority of motor vehicle
manufacturers would not qualify as a
small business. These manufacturers,
along with manufacturers that do
qualify as a small business, would be
able to maintain the current vehicle
designated seating position designation
through design changes outlined in the
proposed definition. The definition
would not require vehicles to have a
certain number of designated seating
positions, but would provide an
objective metric to define the number of
designated seating positions for a given
seat.
Most of the seat manufacturers have
500 or fewer employees. But again, if
design changes are required to maintain
a seats 2–DSP designation, this could be
done by designing a void to the
specifications in the proposed definition
at a minimal cost per seat. Accordingly,
there would be no significant impact on
small businesses, small organizations, or
small governmental units by these
amendments. For these reasons, the
agency has not prepared a preliminary
regulatory flexibility analysis.
C. Executive Order No. 13132
NHTSA has analyzed this proposed
rule in accordance with the principles
and criteria set forth in Executive Order
13132, Federalism and has determined
that this proposal does not have
sufficient Federal implications to
warrant consultation with State and
local officials or the preparation of a
PO 00000
Frm 00047
Fmt 4702
Sfmt 4702
36101
Federalism summary impact statement.
The proposal would not have any
substantial impact on the States, or on
the current Federal-State relationship,
or on the current distribution of power
and responsibilities among the various
local officials. The proposed rule has no
substantial effects on the States, or on
the current Federal-State relationship,
or on the current distribution of power
and responsibilities among the various
local officials.
The proposed rule is not intended to
preempt state tort civil actions, except
that the determination in those actions
of what is a ‘‘designated seating
position’’ would be governed by the
definition and procedure contained in
the Federal motor vehicle safety
standards. We are unaware of any State
standards or determinations setting
forth a conflicting definition of
‘‘designated seating position.’’
Therefore, the agency believes that
federalism implications from this
preemption would be minor.
D. National Environmental Policy Act
NHTSA has analyzed this proposal for
the purposes of the National
Environmental Policy Act. The agency
has determined that implementation of
this action would not have any
significant impact on the quality of the
human environment.
E. Paperwork Reduction Act
This proposed amendment does not
contain any collection of information
requirements requiring review under the
Paperwork Reduction Act of 1995 (Pub.
L. 104–13).
F. National Technology Transfer and
Advancement Act
Under the National Technology
Transfer and Advancement Act of 1995
(NTTAA) (Pub. L. 104–113), ‘‘all Federal
agencies and departments shall use
technical standards that are developed
or adopted by voluntary consensus
standards bodies, using such technical
standards as a means to carry out policy
objectives or activities determined by
the agencies and departments.’’
The proposed amendment is based on
the technical standard SAE J1100
‘‘Motor Vehicle Dimensions,’’ revised
February 2001 and incorporate SAE
J826 ‘‘Devices for use in Defining and
Measuring Vehicle Seating
Accommodations,’’ revised July 1995.
While the procedure for measuring hip
room would be based on SAE J1100, the
proposed procedure include several
qualifiers. First, the proposed procedure
would use the H-point rather than the
SgRP. Second, the proposed procedure
would use the maximum dimension
E:\FR\FM\22JNP1.SGM
22JNP1
36102
Federal Register / Vol. 70, No. 119 / Wednesday, June 22, 2005 / Proposed Rules
measured laterally between the trimmed
surface on the ‘‘X’’ plane through the HPoint rather than the minimum. In
addition, in the case of adjustable seats,
the proposed procedure would use the
position that would produce the
maximum value. These qualifiers would
allow for the largest realistic hip room
to be measured, which would account
for all potential seating. Finally, this
proposal clearly states what is to be
considered continuous seating area for
the purposes of measuring hip room.
This qualifier would objectively define
what constitutes a discontinuity, i.e., an
impediment or void between seat
cushions that would be considered
sufficient to prevent occupant use.
G. Civil Justice Reform
This proposal would not have any
retroactive effect. Under 49 U.S.C.
21403, whenever a Federal motor
vehicle safety standard is in effect, a
State may not adopt or maintain a safety
standard applicable to the same aspect
of performance which is not identical to
the Federal standard, except to the
extent that the state requirement
imposes a higher level of performance
and applies only to vehicles procured
for the State’s use. As explained above,
we are further proposing that the
definition of ‘‘designated seating
position’’ established in the Federal
motor vehicle safety standards preempt
State law, including State tort law, from
establishing a definition that is not
identical. We have tentatively
determined that such preemption is
required to eliminate the potential for
varying definitions, which could result
in a loss in safety. 49 U.S.C. 21461 sets
forth a procedure for judicial review of
final rules establishing, amending or
revoking Federal motor vehicle safety
standards. That section does not require
submission of a petition for
reconsideration or other administrative
proceedings before parties may file suit
in court.
H. Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act
of 1995 requires agencies to prepare a
written assessment of the costs, benefits
and other effects of proposed or final
rules that include a Federal mandate
likely to result in the expenditure by
State, local or tribal governments, in the
aggregate, or by the private sector, of
more than $100 million annually
(adjusted for inflation with base year of
1995). This rulemaking would not result
in expenditures by State, local or tribal
governments, in the aggregate, or by the
private sector in excess of $100 million
annually.

I. Executive Order 13045
L. Regulation Identifier Number (RIN)
Executive Order 13045 (62 FR 19885,
April 23, 1997) applies to any rule that:
(1) Is determined to be ‘‘economically
significant’’ as defined under E.O.
12866, and (2) concerns an
environmental, health, or safety risk that
NHTSA has reason to believe may have
a disproportionate effect on children. If
the regulatory action meets both criteria,
we must evaluate the environmental
health or safety effects of the planned
rule on children, and explain why the
planned regulation is preferable to other
potentially effective and reasonably
feasible alternatives considered by us.
This proposed rule is not subject to
the Executive Order because it is not
economically significant as defined in
E.O. 12866 and does not involve
decisions based on environmental,
health, or safety risks that
disproportionately affect children. The
proposed rule, if made final, would
amend the definition of ‘‘designated
seating position.’’
The Department of Transportation
assigns a regulation identifier number
(RIN) to each regulatory action listed in
the Unified Agenda of Federal
Regulations. The Regulatory Information
Service Center publishes the Unified
Agenda in April and October of each
year. You may use the RIN contained in
the heading at the beginning of this
document to find this action in the
Unified Agenda.

J. Executive Order 13211
List of Subjects in 49 CFR Part 571
Executive Order 13211 (66 FR 28355,
May 18, 2001) applies to any rule that:
(1) is determined to be economically
significant as defined under E.O. 12866,
and is likely to have a significantly
adverse effect on the supply of,
distribution of, or use of energy; or (2)
that is designated by the Administrator
of the Office of Information and
Regulatory Affairs as a significant
energy action. If made final, this
rulemaking would not be a significant
energy action. Therefore, this proposal
was not analyzed under E.O. 13211.

Reporting and recordkeeping
requirements, Tires.
K. Plain Language
Executive Order 12866 requires each
agency to write all rules in plain
language. Application of the principles
of plain language includes consideration
of the following questions:
• Have we organized the material to
suit the public’s needs?
• Are the requirements in the rule
clearly stated?
• Does the rule contain technical
language or jargon that isn’t clear?
• Would a different format (grouping
and order of sections, use of headings,
paragraphing) make the rule easier to
understand?
• Would more (but shorter) sections
be better?
• Could we improve clarity by adding
tables, lists, or diagrams?
• What else could we do to make the
rule easier to understand?
If you have any responses to these
questions, please include them in your
comments on this proposal.

(2) For seats with equal to or greater
than 1400 mm (55.2 inches) of hip
room:
N = [Hip room (in millimeters)/450]
rounded to the nearest whole number.
(b) Hip room is measured as follows:
Calculate the maximum dimension
measured laterally between the interior
trim on the ‘‘X’’ plane through the HPoint within 25 mm (1 inch) below and
76 mm (3 inches) above the H-Point and
76 mm (3 inches) fore and aft of the HPoint. Exclude any portion of this 101
mm by 152 mm area around the H-Point
in side view below and behind the seat
cushion and seat back trim. If the area
is totally excluded by the seat cushion
and seat back trim, measure width to
trimmed door or quarter trim surface
closest, in side view, to the H-Point. If
the seat is adjustable, the position that
produces the maximum measurement is
used. The H-Point location is measured
using the SAE three-dimensional HPoint machine per SAE Recommended
Practice J826, rev. July 1995, with the
legs and leg weights uninstalled.
(1) The hip room measurement
terminates at the vertical projection of
each point on the side profile of the seat
cushion, subject to the conditions of

RIN 2127-AI94
Federal Motor Vehicle Safety Standards; Designated Seating
Positions and Seat Belt Assembly Anchorages
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We are proposing to amend the definition of ``designated
seating position'' in the Federal motor vehicle safety standards
(FMVSSs), and to establish a new procedure for determining the number
of designated seating positions on bench and split bench seats. This
document also proposes to apply that procedure to all types of
vehicles, regardless of weight, and eliminate the existing exclusion
for temporary or folding jump seats. The proposed rule would also
revise test procedures for seat belt anchorage requirements so that
they are suitable for side-facing, temporary or folding jump seats.
NHTSA's goal in proposing these amendments is to improve the
objectivity of the ``designated seating position'' definition and
thereby facilitate efforts of the agency to ensure that the number of
designated seating positions and occupant restraint systems in a
vehicle is representative of real world occupancy.
The proposed rule would also revise the general incorporation by
reference provision for the FMVSSs by providing a centralized index of
all matters therein incorporated by reference.

I. Background
Motor vehicle manufacturers are required to designate which
locations in their vehicles are seating positions. The designation of a
location as a seating position is important for a variety of reasons.
For example, passenger cars are required, under Federal Motor Vehicle
Safety Standard (FMVSS) No. 110, Tire and rim selection, to be clearly
labeled with a maximum seating capacity. Moreover, FMVSS No. 208,
Occupant crash protection, requires that each designated seating
position, as defined in 49 CFR 571.3, in a light vehicle \1\ be
provided with the appropriate occupant crash protection system (e.g.,
air bag, safety belts or both). If a vehicle has fewer designated
seating positions than the number of seated individuals actually
occupying it, some occupants would not be protected by safety belts or
other crash protection systems.
---------------------------------------------------------------------------
\1\ NHTSA uses the term ``light vehicle'' to refer to passenger
cars, multipurpose passenger vehicles, trucks and buses with a gross
vehicle weight rating (GVWR) of not greater than 10,000 lb.
---------------------------------------------------------------------------
In 1978, the agency expressed concern with the common practice of
designating front seats as having two seating positions, although they
had capacity to accommodate three adults (43 FR 21892; May 22, 1978;
Docket No. 78-13). As a result of this practice, front center
passengers were not provided with safety belt assemblies. In response
to this concern, the agency amended the definition of ``designated
seating position'' to specify dimensional parameters. The agency stated
that this was ``intended to ensure that all positions likely to be used
for seating will be equipped with occupant restraint systems'' (44 FR
23229; April 19, 1979). The portion of the definition of ``designated
seating position'' relevant to the above discussion remains unchanged
today.\2\
---------------------------------------------------------------------------
\2\ The definition was amended again in 1995 to allow each
wheelchair position to count as four designated seating positions
for the purpose of determining vehicle classification in school
buses only (57 FR 15504; March 24, 1995).
---------------------------------------------------------------------------
As discussed below, however, field data regarding vehicle occupancy
indicates that there is some ambiguity in the current definition and
that it might not always require what we believe should be a full
complement of designated seating positions (DSPs) to accommodate real
world use.
II. Safety Problem
Vehicle seat design and motor vehicle crash data indicate that in
some instances real world occupancy rates exceed the number of
designated seating positions in a vehicle, particularly on bench and
split seats. The agency has placed a Preliminary Regulatory Evaluation
(PRE) in the docket for this rulemaking that details our findings.
Within the report, a survey of vehicle crash and fatality reporting
systems data indicates that three passengers are occupying seats
designated as having two seating positions (2-DSP seats). The agency
reviewed and compared incidents involving three passengers occupying
either a 2-DSP rear seat or a rear seat with three designated seating
positions (3-DSP seat).
Additionally, the PRE shows a significant decrease in the belt
usage rate when comparing incidents in which two passengers occupied a
2-DSP seat to incidents in which three passengers occupied a 2-DSP
seat. The 1997 to 2001 National Automotive Sampling System (NASS) data
indicated a drop in the belt usage rate for these cases from 53.25
percent to 27.67 percent, respectively. These FARS data indicate that
an occupant is at higher risk when he or she is one of the three
occupants in a rear 2-DSP seat than when in a 3-DSP seat. These risks
appear to be independent of vehicle size and the presence of padded or
carpeted barriers that are intended to limit capacity.
Vehicle size may not adequately limit the number of passengers
occupying a vehicle seat from exceeding the designated capacity. The
fatality rate for a passenger occupying a rear 2-DSP seat together with
two other passengers was only slightly lower for occupants in a Geo
Metro, a sub-compact, than the average rate for occupants of all
vehicles surveyed: 6.02 versus 6.07 fatalities per one million
registered vehicles.
The rate at which one of the three passengers occupying a 2-DSP
seat is killed in a motor vehicle crash also appears to be independent
of the presence of physical features, other than those discussed in the
next paragraph, intended to limit occupancy. The Chevrolet Camaro,
which features a carpeted drive shaft tunnel that separates the two
rear designated seating positions, had a similar fatality rate to that
of the Ford Mustang. While the Camaro has a carpeted barrier, the Ford
Mustang has a rear bench seat with no barrier between the two
designated seating positions. The fatality rate for instances of three
passengers occupying a 2-DSP seat was actually slightly higher for the
Camaro than for the Mustang; 7.81 versus 7.51 fatalities per one
million registered vehicles, respectively.
Conversely, available data demonstrate that certain physical
obstructions in the second row of seating can effectively limit the
number of occupants to the number of designated seating positions. The
Saturn SC Coupe 2 Door had no FARS fatalities involving three occupants
in its 2-DSP second row of seating, and the Acura Integra 2 Door had
only 2.44 such fatalities per one million registered vehicles. Both the
Saturn SC Coupe and the Acura Integra had a hard plastic console that
divides the rear seat into two seating positions, limiting seating
capacity.
In cases in which the same vehicle model was manufactured in both a
two-door (2-DSP second row seating) and a four-door (3-DSP second row
seating) version, the PRE shows that the incident rate for occupants of
the rear seat of the two door version, when occupied by three
passengers, was two-thirds of that of the four-door version, or higher.
While the incident rates may not directly correlate to the frequency of
three occupants using a 2-DSP seat, the
[[Page 36096]]
rates demonstrate that seats designated as having only two seating
positions are being used by three occupants. As a result, at least one
occupant would not have access to a safety belt assembly. A survey of
State Data System (SDS) accident reports compared the two-door (with 2-
DSP second row seating) and the four-door (with 3-DSP second row
seating) models of the Ford Explorer and the Chevrolet S10 Blazer. The
incident rate for second row occupants when three passengers occupied
the second row of the two-door Ford was approximately 64 percent of
that of the four-door model. For the Chevrolet models, incidents
involving three passengers occupying the second row seat for the two-
door model occurred at a rate of 78 percent of that of the four-door
model.
III. Proposed Amendments
The agency is proposing to amend the definition of ``designated
seating position'' to better ensure that seating position designations
more accurately reflect real world occupancy. The proposed amendment
would define ``designated seating position'' based on available hip
room as measured according to procedures established by the Society of
Automotive Engineers (SAE), with qualifications to provide for
measurement of the largest hip room dimension and the incorporation of
H-point in the measurement procedure. We are also proposing a formula
to determine the appropriate number of designated seating positions on
bench and split bench seats according to the hip room measurement. The
formula proposed in this document would further clarify the appropriate
number of designated seating positions for a vehicle seat.
We note that while the agency was already working internally to
address the safety concerns discussed above, we received a petition for
rulemaking from Strategic Safety requesting that the agency establish a
more objective method for determining the number of designated seating
positions (September 10, 2002; Docket No. NHTSA-2002-11398-7). Since
the agency had already initiated work on the issue raised by Strategic
Safety, we view its petition as moot.
A. ``Designated seating position''
If made final, today's proposal would establish a definition of
``designated seating position'' that is more reflective of the
occupancy rates experienced in the real world. By expressly relying on
a hip room measurement for a 5th percentile adult female, instead of
the somewhat less precise and less certain criteria of being large
enough to accommodate such a person, the definition would provide for
more objective determinations of what is a ``designated seating
position.''
We are also making the definition more objective by proposing to
remove language that relies on the likelihood that a location will be
used as a seat while a vehicle is in motion. Currently, a designated
seat position is defined, in part, as:
[Any] plan view location capable of accommodating a person at
least as large as a 5th percentile adult female, if the overall seat
configuration and design and vehicle design is such that the
position is likely to be used as a seating position while the
vehicle is in motion [.]
As evidenced by the current vehicle fleet experience, we believe
that the ``likely to be used'' language does not provide adequate
objectivity to determine when a vehicle seat designation is required.
This difficulty leads to a safety concern when the number of seating
positions designated for a seat differs from the real world occupancy
of that seat. Therefore, we are proposing to replace the ``likely to be
used'' language and incorporate the term ``seat,'' into the definition.
In relying on the term ``seat,'' we recognize that it is not
practicable to design a vehicle to prevent all potential occupant
misuse of interior positions. However, we believe there is abundant
notice to drivers and occupants of light vehicles that the use of
safety belts is essential, and therefore, that sitting in a location in
a vehicle that is not equipped with a safety belt is inappropriate and
dangerous. Vehicle literature and advertising, as well as numerous
public outreach programs, inform and remind the public of the need to
wear safety belts while riding in a vehicle. Vehicle owner's manuals
are replete with exhortations on the importance of always wearing a
safety belt. Further, the warning label required to be on the visor in
every light vehicle expressly tells vehicle occupants to wear safety
belts always. The public's awareness of these messages is evidenced by
the fact that the national safety belt use rate increased from 71
percent in 2001 to 80 percent in 2004, an all time high.
Consistent with the current definition, the proposed definition
would be based on accommodating a 5th percentile adult female.\3\
However, unlike the current definition, the proposed definition would
expressly and exclusively rely on a hip room measurement. A designated
seating position would be any seating location that has at least 330 mm
(13 inches) of hip room,\4\ when measured according to the procedure
described below.
---------------------------------------------------------------------------
\3\ In examining the fatalities that occurred when a seat was
occupied by more occupants than there were occupant protection
systems, we found no definite skew toward child fatalities from the
age distribution in the FARS data that would indicate a need to
consider basing the definition on younger, smaller occupants.
\4\ The 5th percentile female hip width specified in S7.1.4 of
FMVSS No. 208 is of 325 mm (12.8 inches). We rounded the measurement
to 330 mm (13 inches) for purposes of the formula proposed below.
---------------------------------------------------------------------------
B. Measuring Hip Room
NHTSA is proposing to establish a revised procedure for measuring
hip room and to place it in a new section, Sec. 571.10, Designation of
seating positions. Section 571.10 would set out, with several
modifications, the procedure in SAE Recommended Practice J1100 rev.
February 2001, ``Motor Vehicle Dimensions,'' for measuring hip room.
Under SAE J1100 rev. February 2001, hip room of a seat is the minimum
dimension measured laterally between the interior trim \5\ of a vehicle
on the ``X'' plane through the seating reference point (SgRP) within 25
mm (1 inch) below, and 76 mm (3 inches) above the SgRP and 76 mm (3
inches) fore and aft of the SgRP. However, under the proposal, we would
use the H-point as a reference as opposed to the SgRP. SgRP is a design
point designated by a manufacturer, while the H-point is determined by
measurements within the vehicle. Reliance on the H-point would permit
making measurements across an array of seat positions, independent of a
manufacturer's designation.
---------------------------------------------------------------------------
\5\ Interior trim is a molded plastic, fabric or other non-
supportive surface within the occupant compartment (e.g., a molded
arm rest, a carpeted door panel, etc.).
---------------------------------------------------------------------------
While the SAE procedure uses the minimum dimension measured
laterally between interior trim of a vehicle on the ``X'' plane through
the seating reference point, the agency is proposing to use the maximum
dimension. Further, in the case of adjustable seats, the proposal would
use the position that produces the maximum value. These two aspects of
the proposal would result in the largest realistic hip room being
measured, and thus would more accurately account for all potential
seating. Further, the width of a seat would include any void between
the seat and the adjacent interior trim or adjacent seat unless the
void meets certain dimensional criteria.
Hip room would be considered to be continuous under Sec. 571.10,
unless there is a separation greater than 150 mm (5.9
[[Page 36097]]
inches) between adjacent seat cushions, or between a seat cushion and
the vehicle interior, and the separation contains either:
(1) A fixed, unpadded impediment that is at least 5 mm (0.2 inches)
higher than the highest point on the upper surface of the seat cushion
when viewed in profile, which extends for greater than two-thirds of
the horizontal depth of the seat cushions;\6\
---------------------------------------------------------------------------
\6\ A surface covered in carpet or other padding would not meet
this condition. This is in response to the FARS incident data that
showed the carpeted drive shaft tunnel failed to act as an
impediment.
---------------------------------------------------------------------------
(2) A void that can accommodate a rectangular box 150 mm (5.9
inches) wide, 150 mm (5.9 inches) high, and two-thirds of the
horizontal depth of the seat cushion in length, with the box sitting 2
mm (0.08 inches) below each point on the top profile of the seat
cushion \7\; or
---------------------------------------------------------------------------
\7\ See Figure 1 of the proposed regulatory text.
---------------------------------------------------------------------------
(3) A parking brake or gear shift handle, that when placed in the
lowest possible position, is at least 25 mm (1.0 inches) higher than
the highest point of the seat cushion.
These criteria are based on the designs observed in the FARS study
and noted in the PRE, which demonstrated that impediments such as
carpeted barriers are ineffective at preventing three people from
sitting on a seat with only two designated seating positions. The
agency requests comments on whether these specifications would result
in seat designations more reflective of real world occupancy rates.
C. Number of Designated Seating Positions
Section 571.10 would also provide equations for use in determining
the number of ``designated seating positions'' on a seat. The proposed
equations for calculating the number of designated seating positions
would be dependent upon the overall continuous hip room. For seats with
less than 1400 mm (55 inches) of hip room, the measured hip room would
be divided by 400\8\ and rounded to the nearest whole number to produce
the number of designated seating positions. For example, seats with
approximately 1007 mm (39.5 inches) of hip room would be designated as
having three seating positions.\9\
---------------------------------------------------------------------------
\8\ Other international standards use a similar number to
determine the number of seating positions; i.e., Australian Design
Rule 5, Section 10; Automobile Type Approval Handbook for Japanese
Certification, Section 11-1, Article 22.
\9\ 1007 mm of measured hip room divided by 400 equals 2.5,
which would then be rounded up to three.
---------------------------------------------------------------------------
Based on the vehicles surveyed in the PRE, at a seat width of 1007
mm (39.5 inches) and more, three occupants were more likely to occupy a
2-DSP seat, unless a non-padded barrier was present. Requiring seats at
least this width or wider to be designated as having three seating
positions would present manufacturers several options for compliance.
Manufacturers could comply by redesigning their seats to include the
appropriate impediment, provide the necessary void between adjacent
seat cushions, or by installing an additional seat belt assembly. We
anticipate that manufacturers would be more likely to redesign such
seats, if needed, to incorporate an impediment or void as necessary.
The potential vehicle packaging and marketing issues associated with
the addition of a seat belt assembly, along with compliance
implications (e.g., dynamic crash testing, cargo capacity, etc.) would
make this option unlikely. Additionally, issues of comfort might arise
as a result of three occupants being seated at the location. Space
limitations may make it difficult for occupants to use their respective
safety belts when three occupants are seated at such a location.
For seats with 1400 mm (55 inches) or more of hip room, the
measured hip room would be divided by 450 and rounded to the nearest
whole number. The purpose of picking 450 as the divisor is to prevent
larger 3-DSP seats from having to be designated as 4-DSP seats. The
data do not demonstrate a problem with 3-DSP seats being occupied by
four passengers, and does not demonstrate the potential for any benefit
from such a requirement. In addition, for larger vehicles with longer
bench seats (e.g., shuttle buses and limousines), the 450 divisor
results in a designated seating position width that aligns with the
width typically used by seating manufacturers. The rationale for using
two different equations is further discussed in the Benefits and Costs
section.
Under the current definition, any bench or split bench seat in a
passenger car, truck, or multipurpose passenger vehicle with a gross
vehicle weight rating (GVWR) less than 4,536 kilograms (10,000 lb),
having greater than 1270 mm (50 inches) of hip room shall not have less
than three designated seating positions. Under the proposed definition,
the calculation for determining the number of designated seating
positions on a bench or split seat would apply to all vehicles equipped
with such seats regardless of the vehicle weight.
D. H-Point
This document also proposes to update the definition of ``H-
Point,'' which is referred to in the proposed definition of
``designated seating position.'' The current definition of ``H-Point''
references the ``H-Point'' definition in SAE Recommended Practice J826,
``Devices for use in Defining and Measuring Vehicle Seating
Accommodation'' (1962). Since the establishment of the ``H-point''
definition in 49 CFR Sec. 571.3, SAE J826 has been updated (revised
July 1995) and now refers to SAE J1100 for defining ``H-Point.'' This
rulemaking proposes to reference SAE J1100 directly in defining ``H-
point.'' While SAE J826 has been updated, there has been no significant
change to the definition of ``H-Point.'' Further, the proposed ``H-
point'' definition would specify that the H-point is to be determined
using the 3-D test fixture.
E. Auxiliary Seating and Safety Belt Anchorages
We are proposing to include auxiliary seats and jump seats in the
definition of ``designated seating position.'' Currently, the
definition does not include these seats. Since these seats are not
designated seating positions, they are not subject to the occupant
crash protection requirements applicable to designated seating
positions (e.g., safety belt requirements).
Presently, the agency urges that all occupants in light vehicles be
appropriately restrained when a motor vehicle is in operation. When the
agency originally adopted the designated seating position definition,
safety belt use rates were well below 20 percent and the focus of the
agency was not on temporary seats. Now that safety belt use rates are
much higher, the agency is focused on all occupants being properly
restrained. This includes those occupants on auxiliary seats.
If the proposed definition is adopted, auxiliary seats and folding
jump seats would be required to meet all requirements in FMVSSs
applicable to designated seating positions, including the requirements
of FMVSS No. 210, Seat belt assembly anchorages.
Traditionally, manufacturers have classified some side-facing seats
in light vehicles as auxiliary or jump seats. The current test
procedures for the anchorage strength requirements as specified in S5.2
of FMVSS No. 210 were designed for forward and rear facing seats only.
Under S5.2, a force must be applied in the direction in which the seat
faces in a plane parallel to the longitudinal centerline of the
vehicle. For side-facing seats, including auxiliary or jump seats, the
direction that the seat faces is perpendicular to the longitudinal
centerline of the
[[Page 36098]]
vehicle. Consequently, a force cannot be applied simultaneously in the
direction that a side-facing seat faces and in a plane parallel to the
longitudinal centerline of the vehicle. To permit strength testing of
seat belt anchorages at side-facing designated seating positions, we
are proposing to amend S5 of FMVSS No. 210 to specify that for side-
facing seats, the specified force would be applied in the direction
that the seat faces in a vertical plane perpendicular to the
longitudinal centerline of the vehicle.
F. Preemption
Under 49 U.S.C. 30103(b), when a safety standard is in effect under
the FMVSSs, a State is preempted from adopting or retaining a standard
that imposes a different standard of performance, except for vehicles
obtained for its own use. This express preemption clause has been
interpreted as limited to State statutes and regulations based on the
presence in the Safety Act of a provision stating that compliance with
a FMVSS does not exempt ``any person from any liability under common
law'' (49 U.S.C. 30103(c); ``saving clause'').\10\ However, neither the
express preemption clause (by negative implication) nor the saving
clause bars the preemption of state common law in instances in which
state law (tort law) conflicts with uniform Federal safety regulations
of national applicability.\11\
---------------------------------------------------------------------------
\10\ Geier v. American Honda Motor Co., Inc., 529 U.S. 861
(2000).
\11\ ``[T]he saving clause (like the express pre-emption
provision) does not bar the ordinary working of conflict pre-emption
principles.'' Geier v. American Honda Motor Co., Inc., 529 U.S. 861,
869, emphasis original. Indeed, though we are setting forth the
agency's intention in this particular matter, ``the failure of the
Federal Register to address pre-emption explicitly is thus not
determinative. Id. at 884.
---------------------------------------------------------------------------
The definition of ``designated seating position'' would be
established in the section for common definitions for the FMVSSs to
accomplish NHTSA's essential safety objectives. As described below,
differing definitions would not provide the important safety benefits
that NHTSA envisions and could instead be detrimental to safety. Hence,
any differing requirements would ``prevent or frustrate the
accomplishment of a federal objective.'' Crosby v. National Foreign
Trade Council, 530 U.S. 363 (2000). Therefore, if the proposed
definition of ``designated seating position'' would be made final,
section 30103(b) would preempt State statutes and regulations requiring
the designation of more or different seating positions than those
required by that definition.
In addition, if made final, this definition of ``designated seating
position'' would preempt any conflicting determinations in state tort
law as to whether a location is or ought to be a designated seating
position. A tort law determination premised on the designation of more
designated seating positions than those required by the proposed
definition could have a negative safety impact. Such a determination
could result in a location being equipped with a greater number of
safety belts than required under the Federal standards. The
installation of an excessive number of safety belts might decrease, not
increase, safety. Seat belt comfort and convenience are important
factors affecting the level of safety belt use. Occupants might be less
likely to use safety belts because limited space would make such use
difficult or uncomfortable (i.e., if too many safety belts were
installed at a location, some occupants may end up sitting on buckles
or be prevented from reaching his or her respective belt by the
presence of another occupant). The potential for such a scenario would
frustrate the efforts of this agency to base the number of designated
seating positions, and thus the number of safety belts, on reasonably
anticipated occupancy levels. This would hamper our efforts to promote
increased safety belt use rates.
IV. Benefits and Costs
The agency has tentatively determined that there are three ways for
manufacturers to address the proposed amendment to DSP: Add a lap/
shoulder belt; create a space between the seats to restrict the number
of seating positions; and design an impediment to reduce the likelihood
of people sitting in between the outboard seats. If manufacturers were
to add additional lap/shoulder belts, 5 lives would be saved and 41 AIS
\12\ 2-5 injuries would be prevented annually once the proposal is
fully implemented. We believe the other two options would provide
somewhat less benefit than supplying a lap/shoulder belt, although we
are unable to quantify the benefits of an impediment and void because
the benefits are influenced by occupant behavior. The cost of the
proposed change in the DSP definition would depend on which options
manufacturers implemented, ranging from approximately $12 million to
$41.7 million.
---------------------------------------------------------------------------
\12\ The AIS or Abbreviated Injury Scale is used to rank
injuries by level of severity. An AIS 1 injury is a minor one, while
an AIS 6 injury is one that is currently untreatable and fatal.
---------------------------------------------------------------------------
The proposed inclusion of side-facing seats, jump seats, and
auxiliary seats in the definition of designated seating position is not
reflected in the benefit and cost analysis. The agency is unaware of
any current vehicles with side-facing, jump seats, or auxiliary seats
that would not already comply with this proposal, if it were made
final.
Benefits
To estimate the number of lives saved and injuries that would be
prevented if manufacturers chose to add safety belts, the agency relied
on belt use rates, the estimated effectiveness of rear lap/shoulder
belts, and the potential injuries and fatalities to unbelted rear seat
occupants. Based on these estimates, the agency has tentatively
determined that 5 lives would be saved, and 41 AIS 2-5 injuries would
be prevented, annually.
To estimate seat belt usage, the agency relied on an adjusted
average of the rear seat left, middle, and right positions derived from
seat belt use rates generated by the General Estimates System (GES) and
National Occupant Protection Use Survey (NOPUS).\13\ Because GES data
rely on reporting from vehicle occupants, it may overstate seat belt
use. To correct for this, the agency divided the GES estimates by the
seat belt use rate observed in the June 2002 NOPUS study to obtain a
conservative usage rate.\14\ This adjusted factor was then applied to
an average of seat belt use rates for the rear left, rear middle, and
rear right seat positions to generate a seat belt use rate of 64.6
percent for passenger cars and 64.1 percent for light trucks and vans
(LTVs).
---------------------------------------------------------------------------
\13\ Data for GES come from a nationally representative sample
of police reported motor vehicle crashes of all types, from minor to
fatal and relies in part on statements made by vehicle occupants.
NOPUS data is generated through direct observation of occupant
behavior.
\14\ Because NOPUS is based on direct observation of occupant
behavior as opposed to occupant reporting, the seat belt use rate is
less likely to be overstated.
---------------------------------------------------------------------------
Based on previous studies, the agency has estimated the
effectiveness of lap/shoulder belts in the rear seat of passenger cars
and LTVs as follows:
Estimated Percent Effectiveness of Rear Seat Safety Belts \1\
------------------------------------------------------------------------

Restraint Requirements of FMVSS No. 208 to Trucks, Buses, and
Multipurpose Passenger Vehicles with a Gross Vehicle Weight Rating of
8,500 Pounds or Less and an Unloaded Vehicle Weight of 5,500 Pounds or
Less,'' NHTSA, Plans and Policy, Office of Regulatory Analysis,
November 1990.
\2\ Assumed based on 5 percent increase in effectiveness of front seat
AIS 2-5 injuries over fatalities.
The agency then estimated the potential injuries and fatalities
that would occur if in instances in which three passengers occupied a
second row seat with two designated seating positions and none of these
passengers were restrained, to be 77 AIS 2-5 injuries and 21
fatalities. The agency also estimated the potential injuries and
fatalities for LTV occupants in the same circumstances to be 111 AIS 2-
5 injuries and 13 fatalities. All rear seat occupants were included in
the analysis after initially concluding that the improper seating
configuration would potentially affect all rear seat belt usage. The
belt usage data showed a significant decrease in rate when comparing
incidents in which two passengers occupied a 2-DSP seat to incidents in
which three passengers occupied a 2-DSP seat; 53.25 percent belted rate
versus 27.67 percent belted rate, respectively.
To compute the potential injuries prevented and lives saved, the
agency multiplied the number of potential injuries by the effectiveness
of the lap/shoulder belt and by the belt usage rate. This resulted in
an estimation of 11 AIS 2-5 injuries and 2 fatalities prevented for
passenger car occupants and 30 AIS 2-5 injuries and 3 fatalities
prevented for LTV occupants. For a detailed discussion of the benefits
calculation, see the preliminary regulatory evaluation placed in the
docket for this rulemaking.
The benefits of incorporating a void or an impediment depend upon
the occupant's response to the void or impediment. In some scenarios,
the benefits would be the same as providing a lap/shoulder belt; i.e.,
at the time of a vehicle purchase, if a consumer recognizes that there
is not enough room for an additional passenger, even for occasional
trips, the consumer may choose another model vehicle that has three
designated seating positions. In this instance, three safety belts
would be available, and the benefits would be the same as supplying a
third safety belt.
If a seating position were unavailable (because of a void) or
uncomfortable (because of an impediment), an occupant would be less
likely to occupy that space. This would force the extra passenger
either to forego the trip or to go in another vehicle. In either
instance, this reduces the risk of three occupants occupying a 2-DSP
seat. If a seating position is unavailable (because of a void) or
uncomfortable (because of an impediment), but three occupants sit in
the back seat regardless, no benefits will accrue.
Although we cannot estimate the benefits of a void or impediment,
it appears that the overall benefits of providing a void or impediment
would be somewhat less than supplying a lap/shoulder belt.
Costs
The cost of the proposed amendments would depend on whether a
vehicle manufacturer maintained the two seating position designation
for a vehicle's rear seat or if the manufacturer increased the
designated number of seating positions for the rear seat to three. If a
manufacturer were to maintain a seat's 2-DSP designation under the
proposed definition, it could design an appropriate impediment between
seat cushions or design an appropriate void. While there has been no
detailed analysis of the cost of installing an impediment, the agency
has estimated a cost based on the dealership retail prices. The total
cost of installing a rear seat console to impede usage in passenger
cars is approximately $8.03 million (688,207 x $11.67) and in LTVs is
approximately $3.94 million (337,761 x $11.67). The actual cost may be
less than the estimated amount since the agency did not assume a
decrease in seat cost for the reduction of the seat foam material
needed.
A manufacturer may also choose to employ a void. For passenger
cars, incorporation of a void in the rear seats may produce no added
cost; material could be taken out, but the seat would have to be
stitched (more labor) to have the void appear finished. Manufacturers
could also replace a bench seat with two bucket seats. We estimate the
additional cost for substitution at $18.33 per replaced bench seat. If
all affected vehicles had bench seats replaced with bucket seats, the
total cost would be approximately $18.88 million.
A manufacturer could also choose to increase the number of
designated seating positions at a seat and provide an additional seat
belt as required under FMVSS No. 208. FMVSS No. 208 requires passenger
cars, trucks, multipurpose passenger vehicles or buses with a GVWR less
than 4,356 kilograms (10,000 pounds) to have seat belt assemblies for
each designated seating position. The agency recently published a final
rule requiring lap/shoulder belt assemblies in the rear center
designated seating positions (69 FR 70904; December 8, 2004; Docket No.
NHTSA-04-18726; Notice 1). Therefore, it used the cost of the lap/
shoulder belt assembly in that rulemaking to estimate the cost of this
compliance option.
For this analysis, the agency relied on an estimated average cost
of installing a lap/shoulder belt in the rear center seat of
$29.85.\15\ For LTVs, the agency expects the rear center seat belt
costs to be similar to those of passenger cars. Again, using the model
year 2003 sales figure, we estimate that the cost for installing lap/
shoulder belts in the rear center seats of vehicles with an increased
number of designated seating positions would be approximately $30.74
million (1.03 million vehicles x $29.85).
---------------------------------------------------------------------------
\15\ In year 2003 dollars ($2003).
---------------------------------------------------------------------------
For some vehicles, the addition of a seat belt assembly to the rear
center seat would also require reinforcement of the seat to accommodate
an anchorage for the shoulder portion of a lap/shoulder seat belt
assembly. The rear seat of passenger cars and pick up trucks would not
need to be reinforced because the anchors for the shoulder belt could
be attached to the back package shelf or down to the floor frame of the
vehicle without impinging on the floor space or trunk space. However,
this would not be the case for passenger vans and sport utility
vehicles (SUVs). In those instances, the floor space where an anchorage
may be required would be located in occupant or cargo space. Therefore,
the anchorage would need to be attached to the seat itself and the seat
would need to be reinforced. This reinforcement would cost $32.79
($2003) per seating position. The agency estimates that 337,761\16\
vehicles would need to reinforce the rear seat to accommodate an
additional seat belt assembly. The total cost of strengthening the rear
seats of passenger vans and SUVs to accommodate the shoulder portion of
the lap/shoulder belt would be $11.08 million ($32.79 x 337,761
vehicles). This would bring the total cost for adding lap/shoulder
belts to the rear seats of motor vehicles increasing the second row
seating
[[Page 36100]]
position from 2-DSP to 3-DSP to $41.7 million ($2003).
---------------------------------------------------------------------------
\16\ Based on estimated model year 2003 sales of passenger vans
and SUVs.
---------------------------------------------------------------------------
As previously stated, the proposed equation for calculating the
number of designated seating positions varies depending on overall hip
room; for seats with less than 1400 mm of hip room, the hip room is
divided by 400, while a hip room measurement of anything equal to
greater than 1400 mm would be divided by 450. If we used a divisor of
400 for all seats, regardless of width, a seat with 1400 mm of hip room
would increase from 3-DSP under the existing definition in section
571.3 to a 4-DSP seat. Benefits for such a redesignation would be
minimal because the rate at which four persons occupy a seat location
currently designated as a 3-DSP seat is low. Further, the number of
LTVs that would need to be modified would increase by approximately 3.4
times, resulting in cost range of $40.53 million to $217.6 million.
V. Incorporation by Reference
Under 1 CFR part 51, Incorporation by Reference, the agency must
declare that the Director of the Federal Register has approved
incorporation by reference of a publication into a regulation. If made
final, this proposal would amend the general incorporation by reference
provision at Sec. 571.5, Matters incorporated by reference, to include
a centralized index of all of the publications incorporated into part
571.
VI. Effective Date
If adopted, the amendments proposed in this rulemaking action would
become effective on the third September 1st after the date of
publication of a final rule in the Federal Register. For example, if a
final rule were adopted on December 1, 2005, the rule would be
effective beginning September 1, 2008. As stated above, we anticipate
that manufacturers would incorporate a void or barrier in 2-DSP vehicle
seats that, as currently configured, would become classified as having
three designated seating positions. This would require less redesign
than equipping these seats with an additional seat belt assembly. Based
on this assumption, we have tentatively concluded that a minimum of two
years would be adequate time for manufacturers to make any necessary
changes. We request comment on this tentative conclusion.

VIII. Rulemaking Analyses and Notices
A. Executive Order 12866 and DOT Regulatory Policies and Procedures
Executive Order 12866, ``Regulatory Planning and Review'' (58 FR
51735, October 4, 1993), provides for making determinations whether a
regulatory action is ``significant'' and therefore subject to Office of
Management and Budget (OMB) review and to the requirements of the
Executive Order. The Order defines a ``significant regulatory action''
as one that is likely to result in a rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or Tribal governments or
communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budget impact of entitlements, grants,
user fees, or loan programs or the rights and obligations of recipients
thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
This document proposes to amend the definition of designated
seating position in 49 CFR 571.3. The proposed amendment would provide
an objective procedure for determining the number of designated seating
positions present in a vehicle, and provide manufacturers with a more
objective method for delineating designated seating positions. Under
the proposed definition, manufacturers could maintain a vehicle's
current number of designated seating positions by incorporating design
changes at a cost of $11.97 million. By way of example, the Subaru Baja
is currently equipped with a barrier that would maintain a 2-DSP
designation for the second row seat under the proposed amendment.
Further, several previous vehicle models, e.g., the Saturn SC Coupe and
Acura Integra 2-door, were similarly equipped.
This rulemaking document was not reviewed by the Office of
Management and Budget under E.O. 12866. It is not considered to be
significant under E.O. 12866 or the Department's Regulatory Policies
and Procedures (44 FR 11034; February 26, 1979). The agency has
prepared a regulatory evaluation as required by the DOT policies and
procedures. A copy of that evaluation has been placed in the docket for
this rulemaking.
B. Regulatory Flexibility Act
In compliance with the Regulatory Flexibility Act, 5 U.S.C. 601 et
seq., NHTSA has evaluated the effects of this proposed action on small
entities. I hereby certify that this notice of proposed rulemaking
would not have a significant impact on a substantial number of small
entities.
The following is the agency's statement providing the factual basis
for the certification (5 U.S.C. 605(b)). If adopted, the proposal would
directly affect motor vehicle manufacturers and motor vehicle seat
manufacturers. According to the size standards of the Small Business
Association (at 13 CFR Part 121.601), the size standard for
manufacturers of ``Automobile Manufacturing'' (NAICS Code 336111) is
1,000 employees or fewer. Manufacturers of vehicle seats are considered
manufacturers of ``Motor Vehicle Seating and Interior Trim
Manufacturing'' (NAICS Code 336360). The size standard for NAICS Code
336360 is 500 employees or fewer.
The majority of motor vehicle manufacturers would not qualify as a
small business. These manufacturers, along with manufacturers that do
qualify as a small business, would be able to maintain the current
vehicle designated seating position designation through design changes
outlined in the proposed definition. The definition would not require
vehicles to have a certain number of designated seating positions, but
would provide an objective metric to define the number of designated
seating positions for a given seat.
Most of the seat manufacturers have 500 or fewer employees. But
again, if design changes are required to maintain a seats 2-DSP
designation, this could be done by designing a void to the
specifications in the proposed definition at a minimal cost per seat.
Accordingly, there would be no significant impact on small businesses,
small organizations, or small governmental units by these amendments.
For these reasons, the agency has not prepared a preliminary regulatory
flexibility analysis.
C. Executive Order No. 13132
NHTSA has analyzed this proposed rule in accordance with the
principles and criteria set forth in Executive Order 13132, Federalism
and has determined that this proposal does not have sufficient Federal
implications to warrant consultation with State and local officials or
the preparation of a Federalism summary impact statement. The proposal
would not have any substantial impact on the States, or on the current
Federal-State relationship, or on the current distribution of power and
responsibilities among the various local officials. The proposed rule
has no substantial effects on the States, or on the current Federal-
State relationship, or on the current distribution of power and
responsibilities among the various local officials.
The proposed rule is not intended to preempt state tort civil
actions, except that the determination in those actions of what is a
``designated seating position'' would be governed by the definition and
procedure contained in the Federal motor vehicle safety standards. We
are unaware of any State standards or determinations setting forth a
conflicting definition of ``designated seating position.'' Therefore,
the agency believes that federalism implications from this preemption
would be minor.
D. National Environmental Policy Act
NHTSA has analyzed this proposal for the purposes of the National
Environmental Policy Act. The agency has determined that implementation
of this action would not have any significant impact on the quality of
the human environment.
E. Paperwork Reduction Act
This proposed amendment does not contain any collection of
information requirements requiring review under the Paperwork Reduction
Act of 1995 (Pub. L. 104-13).
F. National Technology Transfer and Advancement Act
Under the National Technology Transfer and Advancement Act of 1995
(NTTAA) (Pub. L. 104-113), ``all Federal agencies and departments shall
use technical standards that are developed or adopted by voluntary
consensus standards bodies, using such technical standards as a means
to carry out policy objectives or activities determined by the agencies
and departments.''
The proposed amendment is based on the technical standard SAE J1100
``Motor Vehicle Dimensions,'' revised February 2001 and incorporate SAE
J826 ``Devices for use in Defining and Measuring Vehicle Seating
Accommodations,'' revised July 1995. While the procedure for measuring
hip room would be based on SAE J1100, the proposed procedure include
several qualifiers. First, the proposed procedure would use the H-point
rather than the SgRP. Second, the proposed procedure would use the
maximum dimension
[[Page 36102]]
measured laterally between the trimmed surface on the ``X'' plane
through the H-Point rather than the minimum. In addition, in the case
of adjustable seats, the proposed procedure would use the position that
would produce the maximum value. These qualifiers would allow for the
largest realistic hip room to be measured, which would account for all
potential seating. Finally, this proposal clearly states what is to be
considered continuous seating area for the purposes of measuring hip
room. This qualifier would objectively define what constitutes a
discontinuity, i.e., an impediment or void between seat cushions that
would be considered sufficient to prevent occupant use.
G. Civil Justice Reform
This proposal would not have any retroactive effect. Under 49
U.S.C. 21403, whenever a Federal motor vehicle safety standard is in
effect, a State may not adopt or maintain a safety standard applicable
to the same aspect of performance which is not identical to the Federal
standard, except to the extent that the state requirement imposes a
higher level of performance and applies only to vehicles procured for
the State's use. As explained above, we are further proposing that the
definition of ``designated seating position'' established in the
Federal motor vehicle safety standards preempt State law, including
State tort law, from establishing a definition that is not identical.
We have tentatively determined that such preemption is required to
eliminate the potential for varying definitions, which could result in
a loss in safety. 49 U.S.C. 21461 sets forth a procedure for judicial
review of final rules establishing, amending or revoking Federal motor
vehicle safety standards. That section does not require submission of a
petition for reconsideration or other administrative proceedings before
parties may file suit in court.
H. Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act of 1995 requires agencies to
prepare a written assessment of the costs, benefits and other effects
of proposed or final rules that include a Federal mandate likely to
result in the expenditure by State, local or tribal governments, in the
aggregate, or by the private sector, of more than $100 million annually
(adjusted for inflation with base year of 1995). This rulemaking would
not result in expenditures by State, local or tribal governments, in
the aggregate, or by the private sector in excess of $100 million
annually.
I. Executive Order 13045
Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any
rule that: (1) Is determined to be ``economically significant'' as
defined under E.O. 12866, and (2) concerns an environmental, health, or
safety risk that NHTSA has reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, we must evaluate the environmental health or safety
effects of the planned rule on children, and explain why the planned
regulation is preferable to other potentially effective and reasonably
feasible alternatives considered by us.
This proposed rule is not subject to the Executive Order because it
is not economically significant as defined in E.O. 12866 and does not
involve decisions based on environmental, health, or safety risks that
disproportionately affect children. The proposed rule, if made final,
would amend the definition of ``designated seating position.''
J. Executive Order 13211
Executive Order 13211 (66 FR 28355, May 18, 2001) applies to any
rule that: (1) is determined to be economically significant as defined
under E.O. 12866, and is likely to have a significantly adverse effect
on the supply of, distribution of, or use of energy; or (2) that is
designated by the Administrator of the Office of Information and
Regulatory Affairs as a significant energy action. If made final, this
rulemaking would not be a significant energy action. Therefore, this
proposal was not analyzed under E.O. 13211.
K. Plain Language
Executive Order 12866 requires each agency to write all rules in
plain language. Application of the principles of plain language
includes consideration of the following questions:
Have we organized the material to suit the public's needs?
Are the requirements in the rule clearly stated?
Does the rule contain technical language or jargon that
isn't clear?
Would a different format (grouping and order of sections,
use of headings, paragraphing) make the rule easier to understand?
Would more (but shorter) sections be better?
Could we improve clarity by adding tables, lists, or
diagrams?
What else could we do to make the rule easier to
understand?
If you have any responses to these questions, please include them
in your comments on this proposal.
L. Regulation Identifier Number (RIN)
The Department of Transportation assigns a regulation identifier
number (RIN) to each regulatory action listed in the Unified Agenda of
Federal Regulations. The Regulatory Information Service Center
publishes the Unified Agenda in April and October of each year. You may
use the RIN contained in the heading at the beginning of this document
to find this action in the Unified Agenda.

Anyone is able to search the electronic form of all comments
received into any of our dockets by the name of the individual
submitting the comment (or signing the comment, if submitted on behalf
of an association, business, labor union, etc.). You may review DOT's
complete Privacy Act Statement in the Federal Register published on
April 11, 2000 (Volume 65, Number 70; Pages 19477-78) or you may visit

PART 571--FEDERAL MOTOR VEHICLE SAFETY STANDARDS
In consideration of the foregoing, NHTSA proposes to amend 49 CFR
Part 571 as follows:
1. The authority citation for part 571 would continue to read as
follows:
Authority: 49 U.S.C. 322, 30111, 30115, 30117, and 30166;
delegation of authority at 49 CFR 1.50.
2. 49 CFR 571.3(b) would be amended by revising the definition of
``designated seating position'' and ``H-point'' to read as follows;
Sec. 571.3 Definitions.
* * * * *
(b) * * *
Designated seating position means a seat location that has at least
330 mm (13 inches) of hip room measured according to Sec. 571.10(b) of
this part. The number of designated seating positions at a seat
location is determined according to the procedure set forth in Sec.
571.10(a) of this part. For the sole purpose of determining the
classification of any vehicle sold or introduced into interstate
commerce for purposes that include carrying students to and from school
or related events, any location in such vehic
