Abstract

Abstract An air bag system for an automobile comprises a collision detector for detecting a collision of the automobile, an inflater for generating gas under pressure, based on an output from the collision detector, and air bag device, mounted on a front body member located in front of a seat, for receiving the gas from the gas generator, the gas causing the air bag device to take a predetermined inflated configuration. A seating condition sensor detects a seating condition of a passenger seated on the seat, taking into consideration seat position, reclining angle, passenger size, and posture. A control unit controls operation of the air bag device, in accordance with the seating condition of the passenger, so that the air bag inflated is brought into an optimal contact with the passenger.
