AIRBAG MODULE AND METHOD OF MAKING SAME

摘要

AIRBAG MODULE AND METHOD OF MAKING SAME An airbag module comprising a pyrotechnic inflator device; an inflatable air cushion operatively associated therewith; a retainer for lockingly engaging the air cushion to the inflator and a mounting plate configured and adapted for securing the inflator, the air cushion and the retainer in operative association. A variety of inflator embodiments may be incorporated into the module assembly but each requires, along at least a portion of the housing thereof, a rounded arcuate surface configured for engagement with the retainer upon the formation of a structural seal between the mounting plate and the retainer. This structural seal is created by magnaforming a portion of the mounting plate into a corresponding open groove upon the retainer. The module is thus fabricated by positioning the inflator upon the mounting plate; lockingly engaging the air cushion and the retainer; lowering the retainer/cushion assembly over the inflator and magnaforming the wall of the mounting plate into the groove on the surface of the retainer.
