FRESNEL-VOLUME MULTICOMPONENT MIGRATION

A sensor designed and adapted to operate with vehicle restraints whose primary purpose is to sense low "g" accelerations and vehicle tilting, the results of which lead to the activation or deactivation of the primary occupant restraints through a control module. This invention specifically addresses the reliability of vehicle acceleration and tilt sensors. By employing fewer numbers of components and by having a fewer number of failure mechanisms this invention provides a sensor of increased reliability and lower manufacturing cost. Furthermore, this sensor invention restrains effect z-axis accelerations often encountered when a vehicle is merely traveling over rough roads. This invention employs innovative detector technology, alternatively using an IR detector or a Hall Effect Device detector.
