摘要： A method is described for producing a line-shaped weakening in a flat material by one-sided local removal of the flat material by controllable pulsed laser radiation. The occurring line-shaped weakening is not visible on the surface of the flat material that is not machined and has a reproducible constant breaking resistance.

摘要： An airbag cover in a dashboard, a steering wheel hub cover, or door panel with at least one predetermined breaking line whose shape is substantially determined by a line-shaped weakened portion. The line-shaped weakened portion is a perforation line extending until approximately below the surface visible to the vehicle passengers. This perforation line is advantageously a curve alternating around the predetermined breaking line and is at least similar in shape to the structure of the visible surface.

摘要： 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.

摘要： A method for producing an interior trim part in a vehicle having a decorative layer of leather, wherein the fiber structure of the leather is fixed by undercooling or by a fixing agent at least along a desired weakened line before the weakened line is produced by a laser and for the duration of the laser treatment. The leather comprises a dermis having an underside and a top skin having a decorative side. The weakened line is preferably formed by a series of perforations.

摘要： The present invention relates to the production of a series of holes in a layer of material, in particular to the production of a target rupture line in a first layer of an airbag cover. The radiation of a plasma that forms during the production of each hole is detected from the surface that is being machined. From the signal pattern derived, the time of the beginning of the signal and the time of the appearance of a falling edge that meets a predetermined edge criterion are detected and stored. The point in time at which the falling edge appears is a switching criterion for switching off the laser. The difference between the two points in time stored for each hole constitutes a quality criterion for the respective hole.
