    • An inflator device including a pressure vessel forming a gas storage chamber having contents including a supply of stored pressurized gas. The pressure vessel forms a gas exit opening at a first end of the pressure vessel. An initiator assembly includes an initiator cover that extends through a sidewall of the pressure vessel at a first end portion of the pressure vessel, such that at least a portion of the initiator cover extends radially inwardly into the gas storage chamber. An initiator is positioned within the initiator cover, and produces a discharge effective to rupture a rupturable closure element normally covering the gas exit opening to allow flow of at least a portion of the gas storage chamber contents through the gas exit opening. A first radial aperture formed in the initiator cover is positioned at a direct discharge distance with respect to the closure element to focus the initiator discharge at the closure element to rupture the closure element. In one preferred embodiment of the invention, the inflator device also includes a supply of gas-generating pyrotechnic material contained within the gas storage chamber, wherein at least a portion of the supply of gas-generating pyrotechnic material is reactable to produce a product gas. A second aperture is formed in the initiator cover, and is in reaction initiation communication with the supply of gas-generating pyrotechnic material.
    • 一种充气装置,包括形成具有包含储存加压气体供应的内容物的储气室的压力容器。 压力容器在压力容器的第一端形成气体出口。 引发器组件包括引发器盖,其在压力容器的第一端部处延伸穿过压力容器的侧壁,使得起始器盖的至少一部分径向向内延伸到气体存储室中。 起动器定位在起动器盖内,并且产生有效地破裂通常覆盖气体出口的可破裂闭合元件的放电,以允许至少一部分气体储存室内容物流过气体出口。 形成在起动器盖中的第一径向孔相对于封闭元件定位成直接放电距离,以将引发器放电聚焦在闭合元件处以破坏闭合元件。 在本发明的一个优选实施例中,充气机装置还包括包含在气体储存室内的气体产生烟火材料的供应,其中产生气体的烟火材料的供应的至少一部分可反应以产生产物气体。 在引发器盖中形成第二孔,并且与产生气体的烟火材料的供应反应开始连通。
