    • An inflator (10) includes a housing (12) containing a body (60) of ignitable gas generating material, a body (48) of pyrotechnic material, and an electrically conductive structure (40,44,46) for igniting the body (48) of pyrotechnic material. A closure cap (28) closes the housing (12), and has a passage (190) extending along an axis (18). A tubular structure (220) directs combustion products from the body (48) of pyrotechnic material toward the body (60) of gas generating material, and has an installed position extending axially in the passage (190). The tubular structure (220) and the closure cap (28) have interlocking structures (198,232) for interlocking the tubular structure (220) with the closure cap (28) upon movement of the tubular structure (220) to its installed position in the passage (190).

    • An inflator (14) for inflating an air bag (12) includes a housing (50) containing ignitable gas generating material (60), and an initiator (240) for igniting the gas generating material (60). The inflator (14) further includes a closure cap (56) for closing an end portion (352) of the housing (50), and a retainer (242) for supporting the initiator (240) on the closure cap (56). The closure cap (56) and the retainer (242) have metal surface portions (220,286,290) which extend circumferentially around an axis (40,172) and which are pressed radially against each other to form a seal (332) for blocking gas from exiting the housing (50) between the retainer (242) and the closure cap (56). The metal surface portions (286,290) of the retainer (242) include a cylindrical surface (286) and a frusto-conical surface (290). The frusto-conical surface (290) extends radially inward from the cylindrical surface (286) and is inclined at an angle (A1) from a plane (292) perpendicular to the axis (40). The angle (A1) is within the range of approximately 20.degree. to approximately 40.degree..
    • 用于使气囊(12)充气的充气机(14)包括容纳可燃气体发生材料(60)的壳体(50)和用于点燃气体发生材料(60)的引燃器(240)。 充气机(14)还包括用于封闭壳体(50)的端部(352)的闭合盖(56)和用于将起动器(240)支撑在封闭盖(56)上的保持器(242)。 闭合帽(56)和保持器(242)具有围绕轴线(40,172)周向延伸的金属表面部分(220,286,290),并且被径向压靠在彼此上以形成密封件(332),用于阻止气体离开壳体 (242)和封闭盖(56)之间的空间(50)。 保持器(242)的金属表面部分(286,290)包括圆柱形表面(286)和截头圆锥形表面(290)。 截头圆锥形表面(290)从圆柱形表面(286)径向向内延伸,并且与垂直于轴线(40)的平面(292)以一角度(A1)倾斜。 角度(A1)在大约20°至大约40°的范围内。
