Abstract
An apparatus (24) for inflating an inflatable vehicle occupant protection device (22) comprises a container (40) which provides a source of inflation fluid. The container (40) has an opening (44) through which the fluid can flow to inflate the protection device (22). A support surface (84) is located adjacent the opening (44). A cavity (120) is located adjacent the support surface. A rupturable closure (100) extends across the opening (44) to block the flow of fluid through the opening. A weld (108) forms a fluid seal between the closure (100) and the support surface (84). A member (140) is located in the cavity (120) and has a first portion (144) engaging a surface defining the cavity to secure the member to the container (40). A second portion (142) of the member (140) engages the closure (100) to hold the closure against the support surface (84) of the container (40). The member (140) has an opening (146) through which fluid can flow when the closure (100) is ruptured. An actuatable igniter (160), upon actuation, ruptures the closure (100).
