ABSTRACT:
A vehicle deceleration sensing device making it possible to sense whether an occurring collision is powerful or just trivial. The device comprises a first mass body with an actuating member, a second mass body and a blocking member in the form of a cup spring preventing the second mass body from being displaced at an occurring deceleration of the vehicle until the first mass body has been displaced a predetermined distance indicating that the duration and the magnitude of said deceleration are in excess of predetermined values.
