International ClassB60R 021/26Foreign Application Priority Data1991-07-26 JPAbstractAn air bag device for an assistant driver's seat is formed of a container having an opening for expanding an air bag on the front surface and intake ports for inletting air on the side surfaces; a lid covering the opening; valve plates provided in the container for closing the intake ports an air bag accommodated in the container in the folded state; a gas generator first gas ejecting holes for ejecting gas toward the front surface of the container and second gas ejecting holes for ejecting gas toward the valve plates; and a sealing device attached on the gas generator for sealing the first and second ejecting holes. The sealing device opens only at first gas ejecting hole portions when ejected gas pressure in the gas generator exceeds first predetermined pressure thereby allowing the gas and air flowing through the intake ports to open the air bag. The sealing device opens further at the second gas ejecting hole portions when ejected gas pressure exceeds a second gas pressure higher than the first gas pressure thereby allowing the gas to close the valve plate.Field of SearchWith source of inflation fluid and flow control means thereofWith means to rupture or open fluid source With means to aspirate ambient air With means to diffuse inflation fluid Flow control means JACKETED OR CARTRIDGE GAS GENERATOR For gas-powered tools or means Solid reactant type (i.e., absence of fluid reactants) | |
