Embodiment Construction

[0027] figure 1 Covering material 3 is shown in section for covering an airbag unit (not shown here) in the interior of the motor vehicle, for example in the region of the instrument panel.

[0028] The cover material has on its underside a textile carrier material 1 formed, for example, of polyester threads in the form of a woven fabric, wherein the warp threads run in the longitudinal direction L and the weft threads run in the transverse direction Q; see figure 2 .

[0029] A multi-layer coating 2 is applied to the textile carrier material 1 , wherein the layer directly on the textile carrier material 1 is designated by reference numeral 20 and the layer subsequently applied discretely on the textile carrier material is designated by reference numeral 21 express. These layers are for example compact layers based on PVC or polyurethane, in particular the layer 20 is tailored in its formulation in such a way that it is compatible with the underlying textile carrier materia...

Abstract

The invention relates to a cover material for covering an airbag unit, said cover material comprising a textile backing material (1) made from threads and a coating (2) which is applied to the textilecarrier material (1) on the visible side and is based on thermoplastics, wherein the textile backing material (1) has linear regions (100) in a longitudinal direction (L) and / or in the transverse direction (Q) orthogonal thereto, said regions having a lower strength than in the remaining regions (101) and forming lines of weakness (30) for the cover material (3), and the cover material has a maximum tensile force of 150 to 700 N and a tear propagation resistance of 3 to 45 N along the lines of weakness (30).

Description

technical field [0001] The present invention relates to a covering material for covering an airbag unit, for example in the interior of a motor vehicle as a covering fabric or surface material for instrument panels, door linings, seat structures, etc., in order to hide the airbag unit in a visually Beneath the attractive surface. Background technique [0002] To ensure airbag functionality with such a covering material, it is necessary that the covering material has a visible opening line for deploying the airbag from the start, although this is visually undesirable, or that the covering material is designed to The opening line is weakened in the area to allow deployment of the airbag. To date, this weakening of the material has required additional work steps, such as laser processing or cold knife cutting, resulting in an undesired workload and in addition there is a risk that the weakening line becomes visible, which is undesirable for visual reasons of. [0003] Furthe...
