Abstract
A clamping device for clamping an automotive air bag to an automotive air bag inflator. The clamping device includes an annular retainer ring and module housing. Axial descending members, in the form of tabs, pins, or circular posts are attached to the bottom of the annular retainer and pass through holes in the air bag and module housing. The axial descending members provide additional places wherein the shear stress of the air bag fabric can resist the forces applied to the air bag during deployment. Undersized fastener openings in the module housing in conjunction with annular retainer tabs bent to grasp the module housing clamp the air bag during assembly of the air bag module without installation, thus securing the inflator.
