Abstract:

In 2015 NHTSA published a Notice of Proposed Rulemaking (NPRM) for FMVSS No. 225, Child restraint anchorage systems, that proposed three new requirements for LATCH lower anchors in vehicles: a minimum clearance angle, a maximum attachment force, and a maximum depth of the anchor in the seat bight. These requirements were proposed to improve lower anchor usability and promote correct installation of child restraint systems. After the comment period for the NPRM, NHTSA reevaluated the proposed tools and procedures. This report documents the results of studies done to develop, evaluate, and modify the tools and associated procedures for assessing the usability of LATCH lower anchors. The final rule was published on January 7, 2025.
