OCCUPANT DETECTION SYSTEM

摘要

An occupant detection system (10) for controlling the activation of an air bag inflator (42) incorporates a transmitter/receiver subsystem (16) and a ranging subsystem (20) that respectively measure the distances from a point of reference to the upper seat back (22) and to the region in front of the upper seat back (22). If a normally seated occupant is detected from the difference of the respective distances, then the air bag inflator (42) is enabled. A range/proximity sensing subsystem (14) determines if an occupant is sufficiently close to an air bag inflator (42) to be at risk of injury by deployment thereof, and if so the air bag inflator (42) is disabled.
