ABSTRACT:
A vehicle occupant protective air bag system that first deploys an air bag at a vehicle collision regardless of the presence or absence of an occupant near an air bag device, and subsequently decreases or stops gas flow into the air bag when there is a vehicle occupant near the air bag device. The air bag device has a gas pressure sensor to detect gas pressure inside an air bag. When detection signals from the sensor and an acceleration sensor are transmitted to the control unit indicating a vehicle collision, a controller of the control unit actuates a first of two inflators. If a detector determines that a vehicle occupant is near the air bag device, a second inflator of the two inflators is not actuated. If the detection detects that there is no occupant near the air bag device, the second inflator of the two inflators is actuated.
