Abstract

A process for converting sheet stock into a seamless outer shell for a toroidal shaped hybrid inflator for air bag inflation systems. In the process a seamless toroidal shaped shell is fabricated from sheet stock by a sequence of process steps comprising first drawing the sheet into a cup shaped blank, with curved transitions between the bottom wall and the sidewall, and then shaping the open end of the cup to the desired toroidal shape while simultaneously thickening the areas adjacent to the perimeter of the open end of the cup and finally removing the central portion of the bottom of the cup--thereby producing the desired shell.
