Vehicle safety belt system

摘要

A vehicle safety belt system of the lap and shoulder type comprises a main belt wound on a retractor, the free end of the belt being securable to the vehicle body work, a slidable tongue fitted to the main belt and a main buckle securable to the vehicle body work into which the tongue is lockingly insertable. The retractor prevents the main belt from being withdrawn when the retractor is subjected to an acceleration or deceleration in excess of a predetermined value. The retractor is mounted adjacent the top of the vehicle seat back. The retractor is prevented from moving forwardly in the event of an accident, but is releasable to allow the seat back, and with it the retractor, to be folded forward when desired.
