Improved tear seams for airbag covers

摘要

A covering for use with and instrument panel includes a non-visible tear seam for forming an airbag deployment opening. The tear seam may be formed by cold-knife scoring a stress-riser into the inner surface of the covering at an angle of 85 degrees or less with respect to the inner surface. The angled tear seam may reduce read-through on the show surface of the instrument panel by providing supporting material directly beneath the stress-riser after the scoring.
