An air bag inflator (20, 200) comprises first and second tubes (24, 26, 204, 206) defining respective first and second chambers (44, 46, 244, 246) for storing inflation fluid under pressure. A manifold (22, 202) has a manifold passage (42, 222). Each of the first and second tubes (24, 26, 204, 206)

An air bag inflator (20, 200) comprises first and second tubes (24, 26, 204, 206) defining respective first and second chambers (44, 46, 244, 246) for storing inflation fluid under pressure. A manifold (22, 202) has a manifold passage (42, 222). Each of the first and second tubes (24, 26, 204, 206) is secured to the manifold (22, 202) with the first and second chambers (24, 26, 204, 206) in fluid communication with the manifold passage (42, 222). A diffuser housing (28, 208) is fixed to the manifold (22, 202) and defines a third chamber (104, 242) for fluid communication with the manifold passage (42, 222). Passages (106, 244) in the diffuser housing (28, 208) provide fluid communication between the third chamber (104, 242) and an air bag. A rupturable wall (142, 248) is fixed to the diffuser housing (28, 208) to block fluid communication of the third chamber (104, 242) with the manifold passage (42, 222). An actuatable initiator (122, 246) is in the third chamber (104, 242) for, upon actuation, rupturing the wall (142, 248) to enable fluid communication of the third chamber with the manifold passage (42, 222).

An air bag inflator comprising: first and second tubes defining respective first and second chambers for storing inflation fluid under pressure; a manifold defining a manifold passage; means for securing an end of each of said first and second tubes to said manifold with said chambers extending at an acute angle relative to one another, each of said first and second chambers being in fluid communication with said manifold passage; a housing fixed to said manifold defining a third chamber for fluid communication with said manifold passage; a rupturable wall fixed to said housing and blocking fluid communication of said third chamber with said manifold passage; diffuser passages in said housing for providing fluid communication between said third chamber and an air bag; and an actuatable initiator in said third chamber for rupturing said wall, upon actuation, to enable fluid communication between said third chamber and said manifold passage.
