A crash sensor for automobiles of the type including a ball moving against viscous damping in a closed cylinder for releasing a firing pin for initiating a pyrotechnic sequence has an improved release mechanism. When the ball moves a predetermined distance from its normal or resting position during an automobile crash a release mechanism releases a belleville spring maintained under stress. The belleville spring thereupon initiates movement of a firing pin towards a stab primer. The release mechanism is a single piece of spring material having multiple l...
In a crash sensor of the type comprising a first resilient means for storing energy, an element movable in response to deceleration forces during a crash, and release means adapted to release the energy stored in said first resilient means upon movement of said element to a predetermined position, the improvement comprising: said release means coacting with said first resilient means for constraining it in a stressed state for storing energy, and said first resilient means having a negative spring rate for some range of stored energy.
