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 ).
