| 摘要 |
The invention relates to a covering for an airbag having at least one airbag that is articulated on the stationary covering region surrounding the airbag cover by a textile hinge, wherein the airbag cover and the covering region B surrounding the airbag cover are formed from a sheet material made of plastic, the rear face of which supports a textile surface element having sacrificial threads (2) that extend substantially at right angles to the hinge axis (3) and tear in the region (A) of the hinge when the airbag is activated, and wherein the textile surface element also has stop threads that, when the airbag is activated, allow the airbag cover to pivot about the hinge axis (3) without tearing in the region of the hinge in order to hold the airbag cover securely alter activation of the airbag, wherein the non-tearing stop threads are arranged such that said threads are compressed in the fonts of corrugations and/or loops only in region (A) of the hinge and therefore have a greater length there than in the regions (B) outside the hinge and the region compressed in the form of corrugations and/or loops is located in the plane of the textile surface element. |

1. A cover assembly for an airbag, the assembly comprising at least one airbag cover panel pivotally connected by a textile hinge to a fixed support region surrounding the airbag cover panel, wherein
the airbag cover panel and the support region surrounding the airbag cover are composed of a flat plastic panel whose rear face supports a flat textile element that includes sacrificial filaments that extend essentially perpendicular to a hinge axis and tear at the hinge when the airbag is activated, the flat textile element furthermore includes stop filaments that allow the airbag cover panel to rotate around the hinge axis without tearing in the region of the hinge when the airbag is activated, thereby securing the airbag cover panel in place after the airbag has been activated, the non-tearing stop filaments are compressed in corrugations and/or loops only in the region of the hinge and are thus of a longer length than in the regions outside the hinge, and the corrugations and/or loops are located in a plane of the flat textile element. |
