| Abstract: | In order to prevent injury of the occupant of the passenger seat when a side airbag deploys, we have developed an occupant position detection system. It detects the occupant's head entering the side airbag deployment zone. If so, the side airbag operation is inhibited and an indicator light on the side airbag alerts the occupant to the improper sitting position. It detects accurately the occupant's size and the head entering the side airbag deployment zone, using an occupant identification algorithm and electrostatic capacity sensors under the seat trim cover which determine the dielectric around the seat surface. |
