Abstract

The emergency release is fitted to a vehicle safety belt and disengages this automatically after a shock. It comprises a cylinder (1) fixed to the bodywork (22) and cast containing a spring loaded piston (2, 5). The assembly forms an oil filled dashpot (3, 14), its rod (6) attached to the belt (16) fixing by means of a sleeve (13). Ball bearings (8, 14) in grooves (7, 15) hold this and another sleeve (11) together as a joint, spring biased (12) to prevent dislodgement of the balls. A shock pulls the dashpot piston along the cylinder, the spring returning this after a delay. This movement dislodges the balls in their sleeves, releading these and the belt.
