Abstract: An inflator (10) comprises a container (30) in which inflation fluid is stored under pressure. The container (30) has an opening (40) through which inflation fluid flows from the container. A rupturable closure member (60) is fixed to the container (30) and blocks flow of inflation fluid through the opening (40). The inflator includes an initiator (70) for, when actuated, rupturing the closure member (60) to enable inflation fluid to flow from the container through the opening (40). The inflator (10) also includes a retainer (90) for retaining the initiator (70) on the container (30). The retainer (90) comprises first and second parts (92, 94) that are movable relative to each other when the retainer is not connected with the container (30). The first and second retainer parts (92, 94) when connected with the container (30) cooperate to clamp the initiator (70) in position on the container. The first and second retainer parts (92, 94) define a fluid outlet (108, 140) through which inflation fluid flows from the opening (40) to exit the inflator (10).

Abstract: An inflator (10) comprises a container (30) in which inflation fluid is stored under pressure. The container (30) has an opening (40) through which inflation fluid flows in a given direction from the container. A rupturable closure member (60) is fixed to the container (30) and blocks flow of inflation fluid through the opening (40). The inflator includes an initiator (70) for, when actuated, rupturing the closure member (60) to enable inflation fluid to flow from the container through the opening (40). The inflator (10) also includes a retainer (90) for retaining the initiator (70) on the container (30). The retainer (90) comprises at least one part (94) having a passage (140) for directing gas that flows from the container (30) in the given direction. The inflator (10) also includes a support (150) for the rupturable closure member (60). The support (150) transmits force from the closure member (60) to said retainer (90).

Abstract: An inflator (22) for providing inflation fluid ( ) to inflate an inflatable vehicle occupant protection device (14) includes a container (30) storing the inflation fluid under pressure. The container (30) has an outlet passage (80) through which the inflation fluid flows from the container. A rupturable closure member (92) fixed to the container (30) blocks flow of inflation fluid through the passage (80). A support (100) for the rupturable closure member (92) defines a chamber (110) adjacent the rupturable closure member (92). The rupturable closure member (92) has a first portion (122) deformed into the chamber (110) by the pressure of the inflation fluid and a second ring-shaped portion (124) encircling the first portion (122). An initiator (98) ruptures the closure member (92) when actuated by shearing the first portion (122) from the second portion (124).
