Side-impact airbag module assembly incorporating combination airbag inflator and module housing

摘要

An airbag module housing including an extruded unitary elongated body (16) including: two slotted airbag receiving channels (28, 29); a gas generant chamber (52); four fastener channels (32, 33, 34, 35); gas exhaust ports (26); and cylindrical endplugs (36, 38) held sealingly into ends of the gas generant chamber (52) by endplates (40, 42) and fasteners (48) which engage the fastener channels (32, 33, 34, 35). Each endplate (40, 42) includes an integral mounting bracket (44, 46) and one includes an aperture (43) through which an initiator (58) mounted in the associated endplug (38) is accessible. A folded airbag (14) has a mouth bounded by (i) two tubes (66, 67) which are held in the airbag receiving channels (28, 29) by retainer rods (68, 69) and (ii) cushion ends which are clamped between the endplates (40, 42) and the associated ends (22, 24) of the elongated body (16). A tearable or breakable wrapper (60) holds the airbag in its folded state.
