<p>An occupant sensing and crash behavior system for a motor vehicle determines the presence and location of an occupant (16, 20, 22) to then control the deployment of supplemental restraint systems such as air bags or inflatable seat/shoulder belts. Crash anticipation and crash severity sensors (46, 48) provide additional inputs to the system to determine the behavior of the crash and the occupants therein. An infrared sensor (34) emits a plurality of beams to determine the location and position of the occupant and does a proximity sensor located on the air bag door or the occupant seat. Occupant weight (18) plus the presence and orientation of a child seat are considered. Seat belt control (26) is provided to control the length of the seat belt during an impact or crash.</p> |
