Anthropomorphic Test Devices; THOR 50th Percentile Adult Male Test Dummy; Incorporation by Reference
This document proposes to amend NHTSA's regulations to include an advanced crash test dummy, the Test Device for Human Occupant Restraint (THOR) 50th percentile adult male (THOR-50M). The dummy represents an adult male of roughly average height and weight and is designed for use in frontal crash tests. NHTSA plans to issue a separate NPRM to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 208, ``Occupant crash protection,'' to specify the THOR-50M as an alternative (at the vehicle manufacturer's option) to the 50th percentile adult male dummy currently specified in FMVSS No. 208 for use in frontal crash compliance tests.
Federal Motor Vehicle Safety Standards; Occupant Crash Protection, Seat Belt Reminder Systems
The Moving Ahead for Progress in the 21st Century Act of 2012 (MAP-21) directs NHTSA to initiate a rulemaking proceeding to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 208, ``Occupant crash protection,'' to require a seat belt use warning system for rear seats. Pursuant to this mandate and following on an earlier Advance Notice of Proposed Rulemaking, NHTSA is proposing to require a seat belt warning system for the rear seats of passenger cars, trucks, most buses, and multipurpose passenger vehicles with a gross vehicle weight rating of 4,536 kilograms (10,000 pounds) or less. This document also proposes to enhance the existing front seat belt warning requirements, including requiring a seat belt warning for the front outboard passenger seat and increasing the duration of the warning.
