ABSTRACT:
An apparatus for detecting the collision of a vehicle to produce a signal indicating the collision, which signal is adapted to actuate a safety device, such an apparatus having a pair of rotatable rigid members defining therebetween a space in which disposed is a stationary contact adapted to cooperate with a movable contact carried by the rigid members. Spring means are provided for biasing the rigid members in one rotational direction against a rotational force caused by deceleration of the vehicle. The rigid members are provided with a massive weight so as to make the gravitational center eccentric from the rotational axis thereof, thereby an enhanced sensitivity to the deceleration is obtained.
