ABSTRACT:
An occupant restraint activation sensor includes a light source and a photo responsive detector in optical communication through a light pipe. The severing of this communication by fracturing of the light pipe being indicative of the occurrence of a predetermined impact load on the vehicle because of the mounting of the light pipe on a vehicle structural member whose deflection indicates the occurrence of such a load.
