ABSTRACT:
A deceleration sensor for detecting a threshold level of deceleration indicative of a vehicle collision, comprising a pair of sensor masses in the form of pendulums, a spring-loaded firing pin, a pair of trigger levers which individually hold the firing pin in a dormant state as long as they are held by the sensor masses in their neutral states but can be individually disengaged from the sensor masses by the motion of the sensor masses as a result of detecting a deceleration level greater than the threshold level. Since the firing pin is released only when both the trigger levers are released from their neutral states, the reliability of the dormant state of the firing pin is assured. To the end of improving the reliability of the activation of the firing pin, the firing pin may be spring-loaded by a pair of springs in such a manner that either spring is sufficient for the activation of the firing pin.
