Air cushion restraint device having reinforced inflation attachment

An air cushion occupant restraint system for a motor vehicle of the type having an inflator for generating an inflation gas, comprising:

• an air bag defining an internal volume which is filled with said inflation gas in the event of vehicle impact, said air bag including an inflation gas opening for enabling said inflator to discharge a retainer ring made from a polymeric plastic material affixed to said air bag generally circumscribing said inflation gas opening and having a plurality of posts arranged around said retainer ring, and
• mounting means for securing said air bag to said vehicle including first and second support members which cooperate to clamp against opposing sides of said air bag and said retainer ring around said inflation gas opening, and wherein at least one of said support members includes a plurality of apertures which receive said retainer ring posts.
