Abstract

A method for introducing openings into a decorative material laminated onto a carrier comprises the following steps: providing a fixing device with at least two indicator pins and at least one absorption chamber, providing a carrier with holes for receiving the indicator pins and a decorative material with holes for receiving the indicator pins, pushing the carrier onto the indicator pins and then pushing the decorative material onto the indicator pins. The indicator pins extend through the holes in the carrier and the decorative material and visible parts of the indicator pins protrude above the decorative material, and the decorative material is positioned on the carrier and laminated onto the carrier. Openings are introduced into the decorative material above the openings in the carrier by means of a laser, by detecting the positions of the indicator pins and the heights of the visible parts of the indicator pins.

Abstract

In order to realize the required weakening geometries in a lining material for the hinged cover of an airbag, punctures are produced on the inner side of a lining material by a puncturing needle, wherein the punctures are intermittently produced in the lining material from the inner side, the weakening geometry deviates from a straight line to ensure constant, reliable and defined tearing characteristics of the lining material, wherein for producing the lines of arbitrary weakening geometries by the punctures, the puncturing needle is oriented relative to the desired line direction in one preferred embodiment of the invention, i.e., the cutting edge of the puncturing needle is aligned with the weakening geometry to be produced.

Abstract

The invention relates to a cover for covering an airbag in the interior of a motor vehicle, said cover consisting of a material comprising interspaced perforations which fully penetrate the material in the region of the edge of the airbag flap, said perforations having an essentially linear form and a maximum length of 0.8 mm. The invention also relates to a method for producing a cover for covering an airbag in the interior of a motor vehicle.
