Abstract
An air bag system includes an inflator, an inflatable cushion having an outer face and inflatable upon release of inflation fluid from the inflator, and a restraining tether system. The restraining tether system includes a first tether attached to the outer face of the inflatable cushion, and a second tether attached to the first tether. The first tether is operable to restrain expansion of the inflatable cushion at a first location and a second location spaced from the first location. At least one of the first and second tethers includes a width-reduced portion having a plurality of fabric layers, thereby increasing strength within the restraining tether system.
