Patent Images
1. Supplemental restraint deployment apparatus for a vehicle, comprising:
- a satellite module mounted near a periphery of the vehicle;
primary and secondary crash sensors disposed in said satellite module, said secondary crash sensor utilizing a sensing technology that is different than a sensing technology of said primary crash sensor; and
means for processing primary and secondary crash signals respectively generated by said primary and secondary crash sensors to detect a severe crash event and issuing a supplemental restraint deployment command when said severe crash event is detected.

Abstract
A satellite module mounted near the periphery of a vehicle inboard of a body panel such as a bumper or side door panel includes both primary and secondary (safing) sensors. Response time is enhanced by co-locating the sensors in a satellite module, and reliability is enhanced by utilizing different sensing technologies for the co-located sensors. In a preferred embodiment, either the primary or secondary sensor is responsive to airflow inboard of the body panel due to a crash event.
