Abstract

An interior lining component of an automotive vehicle and method of making same having a support layer and a decorative layer. The decorative layer is joined, either indirectly via an intermediate layer or directly, to the support layer. A series of alternating slits and bridging elements are formed in the support layer along a desired predefined tear seam line. Blind holes of a predefined residual wall thickness and/or microperforation holes extend into the decorative layer along the predefined tear seam line in the region of the bridging elements and in the region of the slits so that the spacing between the holes in the slit regions is narrower than the spacing in the bridging element regions.
