Abstract
An inflatable air bag for restraining an occupant of a vehicle has a deflated, folded condition and an inflated, unfolded condition. When in the folded condition, the air bag has a plurality of folded portions disposed in a stack adjacent to an inflator assembly. A first folded portion is disposed in an outer portion of the stack furthest from the inflator assembly and closest to the occupant. As the air bag inflates, the first folded portion pivots and moves sideways as it moves outwardly from the stack to contact the vehicle occupant. The first folded portion directs the vehicle occupant off to one side of the inflating air bag, and the remainder of the air bag inflates off to the side of the vehicle occupant. As a result, the vehicle occupant does not receive the full force of the inflating air bag.
