ABSTRACT:
An apparatus for controlling actuation of a vehicle occupant restraint system includes a displacement sensor mounted to the vehicle dashboard for sensing the distance between the air bag storage location and the occupant in a seat. An infrared sensor is mounted in the headliner above the occupant. The infrared sensor has a plurality of viewing fields for sensing the location of the occupant relative to the air bag storage location and provides an output indicative of the occupant's location relative to the air bag storage location. A controller determines the distance between the occupant and the air bag storage location from the output of the infrared sensor. The controller is also connected to the displacement sensor. The controller provides an electric enable signal when at least one of the sensors indicates that the occupant is at least a predetermined distance from the air bag storage location.
