For the assembly of the airbag module, the gas generator (14) is first arranged either at the housing (10) or at the holder element (12) and then the holder element is locked at the housing. The gas generator (14) is then already located in its final position in the airbag module.

    Abstract: An airbag device can stabilize an impact absorbing action when an airbag deploys. In the airbag, a front surface portion is coupled with a rear surface portion by straps so that a deployed-shape of the airbag is restricted when the airbag expands. Each of the straps has a tearable portion having a sufficient length. When the internal pressure of the airbag exceeds a predetermined pressure, the tearable portions are torn so as to increase the lengths of the straps, whereby the restriction of the airbag is eased. The internal pressure of the airbag is sufficiently increased before an occupant plunges to the airbag to smoothly absorb an impact simultaneously with the plunge of the occupant, and thereafter, the impact is smoothly absorbed as well.

  • Patent number: 6298789
    Abstract: A gas generator for air bags having a container holding a combustible gas mixture and fitted with a closure which opens into a combustion chamber fitted with a gas outlet in which the gas mixture is ignited by an ignition device. To provide a fast-reacting ignition device and generate a controllable flow of pressurized gas at a relatively low temperature, the container is mainly filled with a pressurized inert gas and contains 0.1 to 2.0% vol. of a hydrocarbon and 0.5 to 10% vol. of a gaseous oxidizing agent. On being actuated, the ignition device opens the container closure, ignites the gas mixture flowing into the combustion chamber and maintains combustion by the continuous supply of energy.
