A cover for an inflatable air bag is provided which has an upper portion adapted to break upon inflation of the air bag and a side portion which extends downwardly from the peripheral edge of the upper portion. An insert is embedded in the cover and includes a flexible net and a flexible reinforcing band assembly. The net includes a side portion embedded in the side portion of the cover and upper portions which are embedded in upper portions of the cover. Coupling portions vertically couple the side portion of the net to the upper portions thereof. The reinforcing band assembly includes a horizontal band which is coupled by for example sewing to the side portion of the net along the entire perimeter of the side portion of the net and vertical bands which are sewn to the horizontal band and to the side edges of the upper portion and/or the coupling portions of the net. The vertical bands of the reinforcing band assembly are bent back at their lower ends so that the lower portions surround the horizontal band and are connected thereto. Since the vertical bands are wrapped around and sewn to the horizontal band, forces which act on the vertical bands when the air bag is inflated are distributed to the horizontal band so that the strength of the cover is great enough to withstand tensile forces which act on the coupling portions of the net. |
