ABSTRACT:
An electronic crash sensing unit for detecting and discriminating a crash and actuating occupant safety device(s) such as air bags. The unit is designed and constructed to operate within an aircraft, but may be used in ground and sea-going vehicles as well. It provides crash acceleration sensing coverage for impact angles occurring throughout aircraft upper and lower hemispherical directions, which are defined by longitudinal, lateral, and vertical aircraft fixed axes as well as any combination of coordinates thereof. It can sense an aircraft acceleration event, determine if the acceleration is a normally occurring event not requiring air bag deployment or a crash event that warrants deployment. The crash sensing unit uses a microprocessor and algorithm to discriminate crash events that warrant safety device deployment from non-crash events, and to actuate deployment. The crash sensing unit compares continuously measured acceleration and calculated total velocity change to defined go
o-go threshold criteria. A crash event is defined as the exceeding both acceleration and velocity change thresholds.
