ABSTRACT:
A method of folding an air bag for a supplemental inflatable restraint system in a vehicle in which the air bag is folded along diverging diagonal lines to form a pointed tail at a location distal from a front edge of the air bag. The air bag is then folded along substantially parallel lateral fold lines to produce a final desired width for the folded air bag. Subsequently, the air bag is formed into a roll starting from the pointed tail and rolling toward the front edge. The rolled air bag is then packed within a module attached adjacent to the front edge of the air bag. During deployment of the air bag, the rolled tail portion of the air bag is initially trapped within the module such that the pressure initially builds within the forward portion of the air bag with improved control over the forces exerted by the air bag.
