    摘要： A method for the introduction of at least one locally limited weakening into a decorative composite, in particular for use in an automotive vehicle, by way of a plurality of laser beams, is disclosed. The decorative composite includes at least one decorative substrate, at least one decorative material and at least one upholstered layer arranged between the decorative substrate and the decorative material. The weakening is formed after the joining of the decorative composite as a sequence of first blind holes or perforations, which penetrate the decorative substrate completely, and unweakened webs between these blind holes or perforations. At least one second blind hole, which does not penetrate the decorative substrate, is introduced into at least one web. The first blind holes or perforations are formed in at least two operations, wherein in a first operation, a preliminary weakening which does not penetrate the decorative substrate completely is introduced into the decorative substrate and, in at least one further operation, at least one subsequent weakening of the decorative composition is introduced through the region of the preliminary weakening. Each subsequent weakening has a smaller cross-sectional area perpendicular to the depth of the decorative composite than the preliminary weakening. A trim element for an automotive vehicle, including a decorative composite produced according to the method is also disclosed.

    摘要翻译： 公开了一种用于通过多个激光束将至少一个局部限制的弱化引入装饰复合材料，特别是用于机动车辆中的方法。 装饰性复合材料包括至少一种装饰性基材，至少一种装饰材料和至少一个装饰基材和装饰材料之间的软垫层。 在将装饰复合材料连接成完整穿透装饰基材的第一盲孔或穿孔序列之后形成弱化，以及这些盲孔或穿孔之间的未经脱水的网。 至少一个不穿透装饰基底的第二盲孔被引入至少一个网。 第一盲孔或穿孔在至少两个操作中形成，其中在第一操作中，完全不穿透装饰基材的初步弱化被引入装饰基材中，并且在至少一个另外的操作中至少一个随后的 通过初步弱化的区域引入装饰组合的弱化。 每次随后的弱化具有垂直于装饰复合材料的深度的较小的横截面积，而不是初步弱化。 还公开了一种用于机动车辆的装饰元件，包括根据该方法制造的装饰性复合材料。

    摘要： The present invention relates to an airbag cover and a method for manufacturing an airbag cover comprising a first layer (1) which is substantially intact in the region of a tear seam for airbag deployment and which borders the space in which the air-bag deploys if the need arises, and at least a second layer (2) which faces the folded airbag, the second layer (2) being attached to the rear side of the first layer (1) to reinforce said first layer (1) and only the second layer (2) having a weakened region (3) to predetermine the run of the tear seam during the deployment of the airbag.
