ABSTRACT:
The invention provides a device for activating a passenger restraining system in a vehicle comprising, a dash-pot assembly arranged to be operatively mounted between the vehicle structure and a bumper on the vehicle, the dash-pot assembly including a cylindrical tube, a closure across the tube and a piston movable in the tube to form with the closure a chamber for pressure fluid in the tube, throttle means in communication with said chamber arranged to control exit of pressure fluid from the chamber and to damp movement of the piston relative to the tube whereby to dissipate energy, and a sensor mounted as an assembly with said tube, the sensor including an electrical switch operable in response to fluid pressure in said chamber.
This arrangement in conjunction with the fact that a dash-pot co-operating with a bumper or fender of a vehicle is one of the first components of the vehicle to be stressed during an impact, provides the advantage of the earliest possible activation of the actuating of an occupant restraining system.
