  • Publication number: 20210221318
    Abstract: The invention relates to a cover material for covering an airbag unit, comprising a textile carrier material (1) composed of threads and comprising a coating (2) based on thermoplastic materials applied to the textile carrier material (1) on the visible side, wherein the textile carrier material (1) has, in a longitudinal direction (L) and/or in the transverse direction (Q) orthogonal with respect thereto, linear regions (100) of lower strength than in the remaining regions (101), which linear regions form weakening lines (30) for the cover material (3), and along the weakening lines (30) the cover material has an ultimate tensile strength of 150 to 700 N and a tear propagation resistance of 3 to 45 N.

  • Patent number: 10132032
    Abstract: An imitation leather including a three-dimensional textile supporting material and a PVC-based covering that is applied to one side of the supporting material and includes three successively applied layers. The first layer of which is applied directly to the supporting material without an adhesion-promoting glue layer, the second layer of which is embodied as an intermediate layer and applied directly to the first layer and the third layer of which serves as a top layer and is applied directly to the second layer. This invention also discloses a method for producing such an imitation leather and an interior component of a motor vehicle having a visible surface that is composed of such an imitation leather.
