    • An inflator for an airbag has a cylindrical housing forming a pressure vessel for storing inert gas within a first end portion; a second end portion forming a separate combustion chamber, and an intermediate diffusion portion interposed between the first and second end portions for exhausting gases from the inflator into an airbag. The inflator has a first gas generator subassembly disposed within the first end portion and in communication with the stored inert gas. A second gas generator subassembly has a combustion chamber which is disposed within the second end portion and isolated from the inert gas by one or more rupturable sealing disks. The actuation of the inflator can be accomplished such that one or both of the gas generators can be ignited. The ignition can be simultaneously or sequential permitting either very rapid full filling of the airbag or slower prolonged filling.
    • 一种用于气囊的充气机具有形成用于在第一端部内存储惰性气体的压力容器的圆柱形壳体; 形成分离的燃烧室的第二端部和介于第一和第二端部之间的用于将气体从充气器排出到气囊中的中间扩散部分。 充气机具有设置在第一端部内并与所储存的惰性气体连通的第一气体发生器子组件。 第二气体发生器子组件具有燃烧室,该燃烧室设置在第二端部内,并通过一个或多个可破裂的密封盘与惰性气体隔离。 可以实现充气机的致动,使得可以点燃一个或两个气体发生器。 点火可以同时或顺序地允许非常快速的充满气囊或较慢的长时间填充。

    • An airbag inflator (200, 300) for inflating an airbag has a tubular inflator housing (11) having a first end (A) and a second end (B). A gas release mechanism (80) has an exhaust port end or housing (85) at the first end (A) for releasing gas directly from the tubular inflator housing (11) to ambient air, bypassing the airbag. A heater assembly (2) containing a gas generant is located and attached at the second end (B). An igniter (3) ignites the heater assembly (2). A primary gas vent port (70) vents gas from the tubular inflator housing (11) into an airbag during normal deployment of the airbag. The gas release mechanism (80) has a passageway or opening (84) for exhausting gas from the tubular inflator housing (11) to an exhaust port (85). A seal (82, 83) seals the passageway or opening (84) of the gas release mechanism (80). An igniter 3 for opens the seal (82, 83) thereby terminating or slowing deployment and normal inflation of the airbag through the primary vent port (70).
    • 一种用于使气囊充气的气囊充气机(200,300)具有带有第一端(A)和第二端(B)的管状充气机壳体(11)。 气体释放机构(80)在第一端(A)处具有排气端口或壳体(85),用于将气体从管状充气器壳体(11)直接释放到绕过气囊的环境空气中。 包含气体发生剂的加热器组件(2)位于并附接在第二端(B)处。 点火器(3)点燃加热器组件(2)。 在气囊的正常展开期间,主气体排放口(70)将气体从管状充气器壳体(11)排出到气囊中。 气体释放机构(80)具有用于将气体从管状充气器壳体(11)排出到排气口(85)的通道或开口(84)。 密封件(82,83)密封气体释放机构(80)的通道或开口(84)。 用于打开密封件(82,83)的点火器3,从而终止或减缓安全气囊通过主排气口(70)的展开和正常膨胀。
