ABSTRACT:
A vehicle crash detecting sensor having a pivoted sensing mass which rotates, in response to vehicle deceleration occurring in a crash of a vehicle, from an at-rest position through a second position of rotation at which time airbag deployment is enabled and then the mass is intentionally rotated through to a third (long dwell) position at a rotational angle much larger in magnitude and in the same direction as that of the second position. The sensing mass is spring biased to always bias the mass during rotation to the at-rest position regardless of the dwell angle of the mass during rotation. By appropriate configuration of the inner wall of the housing to which the other end of the spring, typically an elastica spring, is attached, the part of the spring which touches the wall can be controlled and thereby ensuring that the direction of the torque is always the same,- that is, towards the at-rest position.
