NHTSA has released an SNPRM supplementing its March 2012 NPRM to amend FMVSS 210 to specify a force application device (FAD) for use as a testing interface to transfer loads onto the seat belt anchorage system during compliance tests of anchorage strength. The agency received a number of comments on the NPRM that raised issues concerning the feasibility of the FAD proposal. After reviewing the comments, NHTSA has decided to propose in the SNPRM an alternative test procedure, i.e., one that would maintain the current FMVSS 210 body blocks and adopt procedures ensuring that the placement of the body blocks, at pre-load, is sufficiently specified. The agency is requesting comments on this alternative strategy and other potential enhancements to the current body block test procedure.
Comments will be due 60 days after the SNPRM is published in the Federal Register.
