Abstract
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).
