The Edge-Locking Performance of Some Seat Belt Inertia Reels

摘要

Current accident experience clearly shows the benefits of wearing seat belts both of the static and the inertia reel variety. This report describes tests performed on some designs of inertia reel seat belts to identify possible problems relating to the malfunction of the locking mechanism under heavy braking or impact conditions. The study shows that with some designs there is a slight but significant risk that such malfunctions can occur. (Copyright (c) Crown Copyright 1979.)
