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

An inflator ( ) for inflating an inflatable vehicle occupant protection device ( ) comprises a storage container ( ), a primary inflation fluid under pressure in a gaseous state in the container, and a secondary inflation fluid under pressure in the container. The container ( ) is openable to enable the primary inflation fluid to flow out of the container into the inflatable device to inflate the inflatable device ( ). At least a portion of the secondary inflation fluid is in a non-gaseous state in the container ( ) during flow of the primary inflation fluid into the inflatable device. The portion of the secondary inflation fluid in the non-gaseous state thereafter changing to the gaseous state and flowing into the inflatable device to maintain the inflatable device in the inflated condition.

Long duration air bag inflator

An apparatus ( ) for helping to protect an occupant of a vehicle ( ) comprises an inflatable protection device ( ). The apparatus ( ) also comprises an actuatable inflator ( ) remote from the protection device ( ) for providing inflation fluid under pressure for inflating the protection device. The apparatus ( ) further comprises a conduit ( ) connected in fluid communication between the inflator ( ) and at least a portion of the protection device ( ) for directing inflation fluid from the inflator to the protection device. The conduit ( ) includes at least one quick disconnect coupling ( ) through which inflation fluid flows from the inflator ( ) upon actuation of the inflator.

An apparatus ( ) includes a frame structure ( ) defining a deployment opening ( ), an inflatable vehicle occupant protection device ( ) aligned with the deployment opening ( ), and a deployment structure ( ) extending across the deployment opening ( ). The deployment structure ( ) has first and second locking portions ( ) in releasably interlocked engagement with the frame structure ( ) at locations spaced apart across the deployment opening ( ). The deployment structure ( ) is configured to undergo non-rupturing deflection under the influence of inflation fluid pressure forces applied by the protection device ( ). Such non-rupturing deflection of the deployment structure ( ) moves the first locking portion ( ) partially out of interlocked engagement with the frame structure ( ), and moves the second locking portion ( ) fully out of interlocked engagement with the frame structure ( ).

Vehicle occupant protection apparatus

An apparatus ( ) for helping to protect an occupant of a vehicle ( ) that has a side structure ( ) includes an inflatable vehicle occupant protection device ( ). The inflatable vehicle occupant protection device ( ) is inflatable into a position between the side structure of the vehicle and a vehicle occupant. The apparatus ( ) includes an inflator ( ) for inflating the inflatable vehicle occupant protection device ( ) and for maintaining the inflatable vehicle occupant protection device in an inflated condition for at least five seconds. The inflator ( ) contains a stored inflation fluid under pressure. The inflation fluid consists essentially of helium.

An apparatus ( ) for inflating an inflatable vehicle occupant protection device ( ) comprises a container ( ) defining a chamber ( ). The container ( ) has an opening ( ) through which fluid can flow from the chamber ( ). A quantity of inflation fluid ( ) is in the chamber ( ). A burst disk ( ) closes the opening. The burst disk ( ) has first and second opposite major side surfaces ( ). The burst disk ( ) has a first score line ( ) on the first major side surface ( ) and a second score line ( ) on the second major side surface ( ). The burst disk ( ) is rupturable at the first and second score lines ( ) to permit inflation fluid ( ) to flow out of the chamber ( ) through the opening ( ) in the container ( ).
