摘要： An airbag inflator having a reduced area filter and cartridge-loaded generant. The inflator has a tubular housing with a plurality of exit ports in a limited angular extent. A filter having the general shape of a section of a tube is received within the housing within the extent of the exit ports. The filter has lateral edges which are compressed to reduce the thickness of the filter along these edges, increasing the inner diameter of the filter. A hollow cylindrical cartridge may be provided to house a quantity of pyrotechnic gas generant. The cylindrical cartridge is received within the housing, with the filter interposed between the cartridge and the exit ports. The increased inner diameter of the filter permits the use of a larger diameter cartridge compared to a filter which has not had its lateral edges compressed, which in turn permits a shorter inflator to hold the same volume of generant. The housing may be formed by double impact extrusion to have two separate interiors, each having a generant cartridge. This will permit the cartridges to be fired separately, providing adaptive performance for the inflator.

摘要： A gas generator for vehicle occupant restraint systems comprises an elongated housing having gas outlet openings, a sealed, rupturable gas generant cartridge positioned within the housing, and pyrotechnic gas generant contained in the cartridge in the form of a plurality of wafers having openings defining a central passage. An igniter capsule mounted at one end of the housing has an exit opening juxtaposed the sealed gas generant cartridge and the central passage of the gas generant therein. The igniter capsule contains ignitor material, and an initiator and initiator charge. The initiator ignites the ignitor material which expels a fireball of hot combustion products from the capsules exit opening, rupturing the sealed cartridge and igniting the gas generant charge to produce gas for inflating an air bag. A rupturable seal is provided over the exit opening of the ignitor capsule and a nozzle directs hot combustion products to the gas generant cartridge. The initiator charge is auto ignitor material for operating the gas generator if it is exposed to fire. The ignitor capsule comprises overlapping metal parts, and is mounted as a closure of the elongated housing. The gas generant cartridge is placed in the housing surrounded by filtering and cooling screens. One end of the rupturable gas generant cartridge adjacent the ignitor capsule outlet is scored for rupturing inwardly to admit the ignitor fireball. The cartridge contains wraps of filter screen to provide structural rigidity, and additional filter and cooling materials surround the cartridge.

摘要： An air bag system is provided for use in a motor vehicle. The air bag system includes at least one air bag module. A multiple level gas generation source is coupled to the air bag module for generating a selected gas generation level applied to the air bag module. An electronic control unit controls the operation of multiple level gas generation source. At least one temperature sensor is coupled to the electronic control unit for sensing ambient temperature. At least one seat belt sensor is coupled to the electronic control unit for sensing seat belt usage. An acceleration sensor is coupled to the electronic control unit for sensing deceleration during a crash. The electronic control unit is responsive to a combination of sensed inputs from the temperature sensor, the seat belt sensor and the acceleration sensor for determining both an optimum gas generation level and inflation sequence times for controlling the multiple level gas generation source.

摘要： The application provides airbag cushion deployment restraint systems for use in inflatable airbag cushions. The deployment restraint systems of the invention regulate deployment of an airbag cushion to provide full radial expansion of the cushion prior to final expansion of the cushion toward a vehicle occupant. The deployment restraint systems of the invention thus increase the amount of contact surface area available to a vehicle occupant early in deployment and decrease the force with which the cushion is expanded toward a vehicle occupant during a collision event, thus reducing the likelihood of injury to an out-of-position vehicle occupant.
