Air bag system for a motor vehicle

(57) Abstract: air bag system is provided for use in motor vehicles. The airbag system comprises at least one air bag module. Multilevel gas source is connected to an air bag module for generating a gassing level selected is applied to the air bag module. The electronic control unit controls the operation of the multi-level gas generation source. At least one temperature sensor is connected to an electronic control unit for sensing ambient temperature. At least one seat belt sensor is coupled to an electronic control unit for sensing seat belt use. Acceleration sensors are connected to an electronic control unit for sensing deceleration in a collision. The electronic control unit, in response to the optimum gas generation level and temperature sensor for determining both the inflation continuous time, sensed input from the seat belt sensor and the acceleration sensor combinations for controlling the multi-level gas generation source to.
