The invention is directed to a method for introducing a predetermined break line in a multilayer airbag covering with a carrier layer, a supporting layer and a decorative layer by a laser. In order to prevent an undesirable burning of the supporting layer over a large area as a result of the occurring combustion gases, it is suggested that the carrier material is ablated by a width that is greater than the diameter of the impinging beam to facilitate the escape of the combustion gases.

Method for generating a predetermined break line in a multilayer airbag cover using a laser

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.

A method for introducing a line of weakening with a low opening resistance in an airbag cover, comprising a substrate layer, a foamed material layer and a decorative layer in which a row of pocket holes s generated by laser radiation, wherein, alternately, first groups of pocket holes with a length a and with a quantity x of shallow pocket holes are generated only in the substrate material and second groups of pocket holes with a length b and with a quantity y of deep pocket holes are generated through the substrate material and through the foamed material layer into the decorative layer, and the foamed material layer is retained in the area of the first groups of pocket holes as a supporting layer.

A device for welding a plurality of thermoplastic plastic parts (parts to be joined) forming a hollow body with an opening by a laser, comprising a vacuum holder having a vacuum chamber which communicates with a vacuum pump, is open on one side and, together with the hollow body, forms a closed chamber that can be evacuated. When a vacuum is applied, the vacuum holder holds the hollow body stationary, holds the joined parts together and enables testing of the tightness of the weld.

An arrangement for machining workpieces by a laser, particularly for cutting, perforating, notching, engraving, drilling and inscribing workpieces with three-dimensional structures of different sizes. The laser beam is directed to the workpiece, which is fixed on a holding device, by means of a robot-guided articulated mirror arm and a laser scanner. The laser beam is guided by a coordinated time-controlled and position-controlled deflection of the articulated mirror arm and of the mirror elements of the laser scanner.
