Abstract
A sensor for sensing velocity changes in a motor vehicle and actuating a passenger restraint system for the deployment of an air bag includes a housing 20 containing a pair of contact blades 46, 52 and an inertia element 34 movable without substantial damping in response to a deceleration. The inertia element 34 may be biased towards a rest position by a flexible first contact blade 52 which is bent into contact with a second contact blade 46 when the inertia element 34 moves. Alternatively, the inertia element is magnetically biased to a rest position away from the contacts and completes a circuit through the contacts in response to a deceleration. The housing is mounted on a printed circuit board 84. The system includes a damped second sensor. <IMAGE>
