Abstract
An air bag inflator (20, 220, 420) comprises first and second coaxial tubes (22, 24, 222, 224, 422, 424) which define respective first and second chambers (62, 64, 262, 264, 462, 464). The tubes (22, 24, 222, 224, 422, 424) have terminal ends (42, 44, 242, 244). A weld securement (46, 246, 446) fixes the terminal ends (42, 44, 242, 244) of the tubes (22, 24, 222, 224, 422, 424) together so the chambers (62, 64, 262, 264, 462, 464) extend in opposite directions from the securement (46, 246, 446). The first chamber (62, 262, 462) contains inflation fluid under pressure. The second tube (64, 264, 464) has passages (82, 282, 482) for directing inflation fluid from the first chamber (62, 262, 462) into an air bag. A rupturable wall (66, 266, 466) blocks fluid communication between the first and second chambers (62, 64, 262, 264, 462, 464). A canister (102, 302, 502) in the second chamber (64, 264, 464) has a section which moves to rupture the wall (66, 266, 466) to enable the inflation fluid to flow from the first chamber (62, 262, 462) into the second chamber (64, 264, 464). An energizable initiator (142, 342, 542) is located in the second chamber (64, 264, 464) to, when energized, move the movable section of the canister to rupture the wall (66, 266, 466).
