Abstract
A decration sensor includes a pendulum which is suspended within an U-shaped bucket. The pendulum carries a permanent magnet which is adjacent to a Hall Effect device mounted upon the bucket. Both the pendulum and bucket are carried in an open ended housing which permits movement of the bucket relative to the pendulum to adjust for surface angles when the sensor is mounted upon a vehicle. Upon the deceleration of the vehicle, the pendulum move relative to the Hall Effect Device. As a result of the changing magnetic field, a voltage is generated by the Hall Effect Device which is directly proportional to the vehicle deceleration.
