National Highway Traffic Safety Administration January 23, 2008 – Federal Register Recent Federal Regulation Documents

Federal Motor Vehicle Safety Standards, Child Restraint Systems; Anthropomorphic Test Devices (Hybrid III 10-Year-Old and Hybrid III 6-Year-Old Child Dummies)
Document Number: E8-856
Type: Proposed Rule
Date: 2008-01-23
Agency: National Highway Traffic Safety Administration, Department of Transportation
This document supplements NHTSA's notice of proposed rulemaking (NPRM) of August 31, 2005 that proposed to: (a) Expand the applicability of Federal Motor Vehicle Safety Standard (FMVSS) No. 213, Child restraint systems, to restraints recommended for children up to 80 pounds, and (b) require booster seats and other restraints to meet performance criteria when tested with a crash test dummy representative of a 10-year-old child. In Part 1 of this SNPRM, NHTSA is proposing a test procedure for positioning the 10-year-old child dummy in a child restraint, to reduce variation due to chin-to-lower neck contact that was exhibited by the dummy in sled tests conducted subsequent to the NPRM. Comments are also requested in Part 1 on some other changes or clarifications to the NPRM, proposed in response to the public comments. In Part 2 of this SNPRM, we likewise propose to add a seating procedure for positioning the Hybrid III 6-year-old dummy in a child restraint for FMVSS No. 213 compliance testing. Concerns about the variability in HIC measurements obtained by that test dummy have led NHTSA to postpone mandatory use of the dummy in agency compliance tests. The seating procedure will address this variability issue and facilitate the full use of the dummy as a compliance instrument.
