Vehicle safety belt release mechanism - incorporates latch plate and spring system to free belt after force application due to impact

摘要

A vehicle safety belt has a locking mechanism designed to automatically release the belt after an accident has occured to that the user is freed without further assistance. The end of the belt carries a joggled plate (G) retained at the top edge by two latch arms (d') and hooking behind a lip in a retainer piece at the bottom. When force is applied against the locking tab (E) through which the latch arms pass. This moves a plate (D) carrying the hooks and compresses a leaf spring (C) behind it. This releases the latches from the plate (G) and a forked plate (F) behind the tab (E) releases the plate.
