ABSTRACT:
An inertial sensor device for automatically operating warning means in an automotive vehicle is provided which comprises an inertia block slidably mounted in tubular guide means and sensitive to acceleration and deceleration of the vehicle in two opposite predetermined directions relative to the axis of the vehicle, the inertia block being normally biased by two springs oppositely acting on said block to prevent a striker from moving into a striking position until inertial forces in one or the other of said directions are developed sufficiently to move the inertia block, against the action of said springs, a sufficient distance to release the striker for operating a utilization device.
