Quantifying Belt Tension in CRS Installations with Lock-off and Tensioning Features

Principal Investigator: Julie Mansfield, PhD, The Ohio State University

Some child restraint systems (CRS) have built-in tensioning features, such as a door or clasp that closes over the seat belt, that apply tension to the belt to achieve a snug installation. This study aims to quantify how much tension these features produce on the belt to ensure consumers can use the features correctly and that the tensions they produce are similar to current FMVSS 213 test guidelines.

This project is currently underway. Further information will be added in late 2023 following project completion.
