Abstract
An attachment system, an air bag module subassembly and a method of attachment are provided for the fastenerless attachment of an inflatable cushion into a restraint system. A thickened gas inlet opening of the inflatable cushion is secured within a channel portion of a cushion retainer to form a cushion/retainer subassembly wherein the secured inlet opening forms an attachment insert. The attachment insert is inserted into an attachment sleeve portion of the reaction housing to secure the cushion to the housing.
