<p>An occupant detection system (10) for controlling the activation of an air bag inflator (40) incorporates a transmitter/receiver subsystem (20) that generates a beam of wave energy (28, 25) through a region that is occupied by a normally seated occupant and that is not occupied by either an out-of-position occupant or by a rear facing infant seat. If a normally seated occupant is detected from the interaction of an occupant with the beam of wave energy (28, 25), then the air bag inflator (40) is enabled. A range/proximity sensing subsystem (30) determines if an occupant is sufficiently close to an air bag inflator (40) to be at risk of injury by deployment thereof, and if so the air bag inflator (40) is disabled.</p> |
