ABSTRACT:
An air bag inflator (20) comprises a container (22) defining a chamber (42) for storing inflation fluid under pressure. The container (22) has an opening (44) through which the inflation fluid flows from the chamber (42) for inflating an air bag. An initiator (26, 226, 326, 426) includes a housing (84, 240, 328, 428) which contains an actuatable device (164). A closure (86, 242, 344, 464) forms a portion of the housing (84, 240, 328, 428) and is fixed to the container (22) to block the flow of inflation fluid from the chamber (42). The housing (84, 240, 328, 428) is rupturable in response to actuation of the actuatable device (164) and is rupturable in response to the pressure of the inflation fluid in the chamber (42) reaching a predetermined pressure when the actuatable device is unactuated. The housing may rupture in different areas (102, 108, 122, 246, 262, 362, 364, 386, 464, 484) depending on whether the rupture occurs in response to actuation of the actuatable device or in response to the pressure of the inflation fluid reaching the predetermined pressure.
