    • Gas generator for an inflatable impact cushion for protecting an occupant of a motor-vehicle from injury, has a housing, in which is formed a storage chamber for liquid gas. The storage chamber is separated by a partition wall from a combustion chamber also formed in the housing. An ignition device is positioned in a precombustion chamber, and has an ignition charge to generate combustion gases during ignition. In the precombustion chamber there is guided, in a displaceable manner, a piston which, because of the combustion gases of the ignition charge, moves into and through the combustion chamber in a direction of the partition wall, in order to penetrate the partition wall. When the partition wall is penetrated there is a connection between the storage chamber and the combustion chamber by way of a liquid gas channel system so that liquid gas can flow into the combustion chamber. At the same time a connection is created between the precombustion chamber and the (main) combustion chamber by way of ignition channels formed in the piston. The hot combustion gases of the ignition charge ignite the liquid gas flowing in. The rising internal pressure in the combustion chamber causes a displacement of the longitudinally displaceably guided partition wall, which moves together with the piston and thereby continuously injects liquid gas from the storage chamber into the combustion chamber. The combustion gases emerge by way of annular chambers, connected in series, through outlet openings in the housing.

    • Gas generator for an inflatable impact cushion for protecting an occupant of a motor-vehicle from injury, has a housing, in which is formed a storage chamber for liquified gas. The storage chamber is separated by a partition wall from a combustion chamber also formed in the housing. An ignition device is positioned in a precombustion chamber, and has an ignition charge to generate combustion gases during ignition. In the precombustion chamber there is guided, in a displaceable manner, a piston which, because of the combustion gases of the ignition charge, moves into and through the combustion chamber in a direction of the partition wall, in order to penetrate the partition wall.

At the same time a connection is created between the precombustion chamber and the (main) combustion chamber by way of ignition channels formed in the piston. Hot combustion gases of the ignition charge ignite the liquified gas. The rising internal pressure in the combustion chamber causes displacement of the longitudinally displaceably guided partition wall, which moves together with the piston and thereby continuously forces liquid gas from the storage chamber into the combustion chamber. The combustion gases emerge, through outlet openings in the housing.

    • An ignition unit is provided with an internal housing defining a chamber in which an ignition charge and an ignition element igniting the charge are accommodated. The housing defining the chamber consists of a cover and a container which are connected to one another along a circumferential groove. A distributor housing is mounted on to the housing forming the chamber, in which distributor housing gas outlet openings are provided which are closed by a cap-shaped cover of the chamber. The V-shaped circumferential groove represents a predetermined breaking or separation position of the chamber, for which reason the cover is separated from the container when the ignition charge is ignited. The cover moves away from the container into a space until it strikes the upper end of the distributor housing. With its movement relative to the distributor housing, the cover releases the gas outlet openings so that the gases and flames can emerge from the ignition unit.
    • 点火单元设置有限定室的内部壳体,其中容纳着火电荷和点燃电荷的点火元件。 限定腔室的壳体由沿着周向槽彼此连接的盖和容器组成。 分配器壳体安装在形成腔室的壳体上,其中设置有分配器壳体气体出口,其由腔室的盖形盖封闭。 V形周向沟槽表示室的预定的断裂或分离位置,为此,当点燃电荷点燃时,盖与容器分离。 盖子从容器移动到空间中,直到其撞击分配器壳体的上端。 通过其相对于分配器壳体的运动,盖释放气体出口开口,使得气体和火焰可以从点火单元出来。

    • A gas generator is provided with a housing which is open at two opposing end faces and a housing wall in which several gas orifices are arranged. The housing is formed as an extruded hollow profile of aluminum or an aluminum alloy. A combustion chamber is accommodated in the housing, in which combustion chamber gas-generating material which is ignitable by means of an ignition unit is accommodated. The combustion gases arising with the ignition of the gas-generating material are cleaned within the housing by filter elements and discharged by means of the gas orifices. The filter elements are supported by holding sections integral with the extruded hollow profile and are inserted by means of one of the open end faces of the extruded hollow profile. In the installed state the filter elements extend in a straight line between the holding sections associated therewith.
