A method for producing a plastic substrate for an interior paneling part of a motor vehicle and the resulting plastic substrate. The plastic substrate has a flap for the passage of an airbag. The hinge areas of the lid are reinforced by a mesh fabric part. Preferably the fabric part has a wide mesh. During production, the fabric part is first inserted in the injection mold in the position of the future flap. During the subsequent injection molding, the plastic mass presses the fabric part on the one side against the interior mold wall, but also penetrates it through the wide mesh structure. After casting, tear lines, which define the opening contour of the flap, are produced, preferably by laser beam machining. Further, fabric sections situated outside the hinge areas may be severed and the plastic areas situated behind them weakened.
A method of producing a plastic substrate for an interior paneling part of a motor vehicle, wherein a plastic substrate with an integral flap for the passage of an airbag is produced by injection molding, the flap being swivellable in the opening direction by way of a hinge provided on the plastic substrate, and the hinge being reinforced by a fabric part, wherein the fabric part has a mesh structure, said method comprising the steps of:
