Grain-coordinated airbag tear seam
Abstract:
A vehicle interior panel for use over an airbag includes a decorative covering with a grain-coordinated tear seam. The decorative covering includes a visible surface with a grain pattern formed therein, and individual stress risers of the tear seam a located at valleys of the grain pattern. Holes cut through a skin layer of the decorative covering in this manner have reduced visibility, due in part to light reflection characteristics at the grained surface that tend to form shadowed areas in the grain valleys. A method for forming a grain-coordinated tear seam includes determining the location of peaks and/or valleys of the grain pattern and forming a majority of the stress risers at determined valley locations.
