Abstract
An airbag module incorporates an inflatable airbag cushion having an inflatable body and a collar defining an open mouth for receiving inflation gas, with a stiffening collar ring secured to the collar. The airbag module also includes an inflator and a module housing, the inflator having a peripheral bracket extending radially outwardly and the module housing having an opening. The collar of the airbag cushion extends through the opening and the inflator fits within the open mouth of the airbag cushion with the collar ring and collar seated between the module housing and the peripheral bracket. Clamping structure secures the airbag cushion to the airbag module. The clamping structure is an inwardly facing c-shaped ring having a top leg secured to or integral with the module housing and a bottom leg, with the peripheral bracket, the collar ring and the collar clamped between the legs. In another embodiment, the airbag module includes a c-shaped ring clamping the collar ring and the collar to the peripheral bracket. In a further embodiment, the peripheral bracket of the inflator includes a distal end curled over to clamp the collar ring and the collar to the peripheral bracket.
