Air bag system for automobile
First Claim
1. An air bag system for an automobile comprising:
- collision detecting means for detecting a collision of the automobile,gas generating means for generating a gas under pressure, based on an output of said collision detecting means,shock absorbing bag means mounted on a front body member located in front of a seat for receiving the gas from the gas generator to take a predetermined inflated configuration,seating condition detecting means for detecting whether or not a passenger seated on the seat has put a seat belt on, andcontrol means for controlling a time period between a collision and complete inflation of the shock absorbing bag means in accordance with the seating condition of the passenger so that the shock absorbing bag means, when inflated, is brought into an optimal contact with the passenger, the control means advancing timing of the inflation of said shock absorbing bag means when said seating condition detecting means detects that the passenger has not put a seat belt on.

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.
