Method for introducing a line of weakening with low tearing resistance into an airbag cover and airbag cover produced by this method

An airbag cover with a line of weakening having a low opening resistance, comprising:

• a substrate layer;
• a foamed material layer and a decorative layer;
• and
• a line-shaped arrangement of pocket holes which extends in the airbag cover and forms the line of weakening;
• said arrangement of the pocket holes comprises alternately arranged first groups of pocket holes with a length (a) and a quantity (x) of shallow pocket holes and second groups of pocket holes of a length (b) and a quantity (y) of deep pocket holes, and the shallow pocket holes only project into the substrate layer and the deep pocket holes project through the substrate layer and foamed material layer into the decorative layer, so that the foamed material layer remains in the area of the first groups of pocket holes as a supporting layer.
