    摘要: 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).

    摘要: An initiator (40) for actuating an inflation fluid source (34) for an inflatable vehicle occupant protection device (36) comprises a plurality of electrically energizable microelectromechanical system (MEMS) devices (120-126). In one embodiment, the MEMS devices (120-126) are associated in a one to one relationship with chambers (75-78) containing ignitable material (130). Each one of the MEMS devices (120-126), when energized, generates combustion products, including heat, for igniting the associated ignitable material (130). At least one terminal pin (44-46) is electrically connected with the plurality of MEMS devices (120-126) for receiving an electric signal for energizing at least one of the MEMS devices.
