Vehicle occupant restraint module with disk inflator

摘要

A novel vehicle occupant restraining module is described. The retraining module includes an inflatable cushion having an inner surface and an outer surface. The inflatable cushion is capable of receiving inflation fluid from an inflation fluid source. A retaining collar is positioned adjacent a mouth of the cushion and about the inflation fluid source to retain the inflatable cushion in communication with the inflation fluid source. The retaining collar includes a flange that flares elliptically outward from the inflation fluid source. The retaining collar also includes an extension tab for preventing the cushion from contacting the inflation fluid source after inflation.
