Abstract

A seat belt pre-tensioning device is adapted to be mounted on a vehicle and includes a buckle to receive a seat belt buckle. The device incorporates components which are responsive to a predetermined deceleration of the vehicle and which move to permit spring-loaded components to apply a force to move the buckle to apply a tension to the seat belt.
