Air bag cushion retention method.

摘要

A vehicle occupant air bag module safety apparatus includes an inflatable air bag cushion (48), an inflator (50) for inflating the air bag cushion, and a module housing (52) or mounting plate for supporting the air bag cushion (48) and the inflator (50) on a steering wheel. For securing the air bag (48) to the inflator (50) and the module housing (52) or mounting plate an annular portion of the air bag adjacent its gas inlet opening (49) is clamped by studs (78) and nuts (80) directly between the module housing (52) located exteriorly of the air bag (48) and an inflator flange (60) located interiorly of the air bag (48). An annular portion (76) of the air bag (48) immediately surrounding its inlet opening (49) is clamped between an annular curved portion (74) of the module housing (52) and a complementarily curved region of the inflator (50) connecting the inflator flange (60) to a lower wall portion (68) of the inflator (50). <IMAGE>
