OCCUPANT DETECTION SYSTEM

摘要

An occupant detection system (10) for controlling the activation of an air b ag inflator module (16) incorporates radar module (12), the activation of which is responsive to an activation sensor responsive to either the likelihood of a crash or to the liklihood of injury from the air bag inflator module (16) as a result of proximity thereto. In one embodiment, responsive to a potential crash, the air bag inflator module activates the radar module (12) for a period of time to sense if an occupant is within the at-risk zone of the air bag inflator module. In another embodiment, the activation of the radar modu le (12) is responsive to a continuously active range/proximity sensor (22). The air bag inflator is disabled if an occupant is detected within the at-risk zone of the air bag inflator module (16).
