Problems solved by technology

With this leather, however, more complex switching elements cannot be realized, in particular, since the requirements of the contact area in terms of protection against possible penetration of sweat and grease cannot be met, and the risk of short circuits in turn cannot be sufficiently avoided, it is therefore not possible to produce switching elements produced by interconnection.

Embodiment Construction

[0038] Figure 1A A connection 1 between two composite parts 2 of a leather composite according to a first exemplary embodiment of the invention is shown. The composite part 2 is, for example, a leather die-cut, in which case the composite part 2 has a leather layer 3 and a leather finish 4 applied to a sanded base of the leather layer 3 . If the leather layer 3 is made of animal hide, it can be adjusted to an elongation value of 10%±5%, preferably an elongation value of 7% to 12%. This is achieved by various tanning processes known to those skilled in the art. Alternatively, the leather layer 3 can be made of artificial leather known to those skilled in the art. The primer (i.e. the first finish layer or the first varnish layer of the leather facing 4) can be made from polyurethane and / or acrylate based binders and fillers known to those skilled in the art, or from silicate and polymer and / or carbon based organic fillers. The primer can be adjusted to an elongation value o...

Abstract

The invention relates to a leather composite, comprising at least two composite parts (2), which are characterized by a layer structure that comprises: a leather layer (3) produced from a hide or a layer of artificial leather; a leather dressing (4) applied to a leather surface of the leather layer (3) or to a sanding base; and at least one electronic layer (7), which is inserted into the leather dressing (4) or applied to the leather dressing (4). At least two composite parts (2) are mechanically sewn to one another, with mutually facing surfaces (9, 10) of the leather dressing (4) and / or of the electronic layers (7), along at least one seam (8) of a connection (1, 20, 30), the electronic layers (7) of the composite parts (2) additionally forming at least one common electrical contact in at least one contact region (13) of the connection (1, 20, 30), which contact region (13) has a greater distance (A) from a visible surface (5) of the leather composite than the seam (8) does.

Description

technical field [0001] The invention relates to a leather composite comprising at least two composite parts characterized by a layer structure having a leather layer consisting of an animal hide or artificial leather layer, a leather surface applied to the leather layer or buffed A leather finish on a substrate and at least one electronic device layer incorporated into and / or applied to the leather finish and the invention relates to a method for producing such a leather composite. Background technique [0002] For leather applications in general and especially in the automotive sector, e.g. for covering seats or steering wheels, there is an increasing demand for leather materials consisting of leather compounds comprising as much as possible Small composite parts. Such composite parts are preferably obtained from leather scraps. Leather composites made of such composite parts are especially cheaper and more flexible in terms of their design and composition, for example in...
