Abstract

An air bag for a vehicle has a peripheral part of an occupant-associated panel and a peripheral part of an inflator-associated panel stitched together. At portions of the peripheral part of each panel where constituent threads of a fabric of that panel and a contour line of the air bag are substantially parallel, the peripheral part of the other panel stitched thereto is curtailed to form a curtailed portion where threads and the contour are not parallel. As result, the thread-contour substantially parallel portions are easily bent by gas flow on inflation of the air bag and an amount of thread fraying occurring on inflation of the bag is reduced by the bending.
