An airbag cover assembly for the passenger side of an automobile. The assembly includes an exterior skin, a pair of underlying sub-assemblies, each including a U-shaped galvanized steel strip, a short nylon scrim and a long glass mat sandwiched therebetween and extending therefrom such that a narrow space exists between adjacent edges of the glass mats. A weakening notch is formed across the inside surface of the exterior skin along the center line of the narrow space. A low density polyurethane foam is injected into a foaming tool cavity bearing the skin and pair of sub-assemblies. When cured, the foam covers the nylon scrims and glass mats and becomes immersed throughout the interstices of each, serving as the body of the final assembly. The glass mats prevent fragmentation of the low density foam upon deployment of the airbag.
