Plastic skin having conductors

1. A plastic skin as a surface cover for a part for the interior of a vehicle, the plastic skin comprising:

an electric conducting path embedded in said plastic skin;

said plastic skin being composed of a plastic material; and,

said electric conducting path being a mixture of said plastic material of said plastic skin and a conducting material wherein:

said plastic material is polyvinylchloride (PVC);

said conducting path is a mixture of said polyvinylchloride (PVC) and graphite or a mixture of polyvinylchloride (PVC) and carbon black;

said plastic skin has a layer thickness: and,

said conducting path is arranged as an intermediate layer within said layer thickness of said plastic skin.

2. The plastic skin of claim 1 , wherein said mixture of said conducting path contains carbon fibers or metal powder as said conducting material.

3. The plastic skin of claim 1 , wherein:

said plastic skin has a back side; and,

said conducting path is arranged on said back side of said plastic skin.

4. A method of making a plastic skin as a surface cover for a part for the interior of a vehicle wherein the plastic skin includes an electric conducting path embedded therein; the plastic skin is composed of a plastic material; and, the electric conducting path is a mixture of said plastic material of said plastic skin and a conducting material, the method comprising the step of:

working said conducting material into said plastic material in a rolling-kneading process.

5. A method of making a plastic skin as a surface cover for a part for the interior of a vehicle wherein the plastic skin includes an electric conducting path embedded therein; the plastic skin is composed of a plastic material; and, the electric conducting path is a mixture of said plastic material of said plastic skin and a conducting material, the method comprising the steps of:

constructing said plastic skin as a mold skin via a repeated melting of plastic materials on a surface area of a heated mold;

then removing said mold skin from said mold; and,

wherein said repeated melting includes the steps of:

first applying at least one layer of said plastic material of said plastic skin onto said mold;

melting said plastic material on said mold;

thereafter applying a mixture of said plastic material of said plastic skin and said conducting material; and,

melting said mixture of said plastic material and said conducting material.

6. The method of claim 5 , wherein said repeated melting comprises the steps of:

first applying a layer of said plastic material in the form of a powder to the mold and melting said plastic material; and,

then applying the mixture of said plastic material of said plastic skin and said conducting material in the form of a powder mixture and melting said mixture.

7. The method of claim 6 , wherein the powder mixture is applied to the surface of the already applied plastic material of said plastic skin with the aid of a spray method or a rotation sinter method.

8. The method of claim 5 , wherein repeated melting comprises the steps of:

first applying a layer of said plastic material of said plastic skin in the form of a powder to the mold and melting the same; and,

thereafter applying said mixture of said plastic material of said plastic skin and a conducting material in the form of a mixture disposed in a solution and melting the same.

9. A method of making a plastic skin as a surface cover for a part for the interior of a vehicle wherein the plastic skin includes an electric conducting path embedded therein; the plastic skin is composed of a plastic material; and, the electric conducting path is a mixture of said plastic material of said plastic skin and a conducting material, the method comprising the steps of:

first producing said plastic skin as a rolled foil; and,

then applying a mixture of said plastic material of said plastic skin and said conducting material and bonding said mixture to said plastic skin in the form of a rolled foil.

10. The method of claim 9 , wherein said mixture is pressed onto said rolled foil.

11. The method of claim 9 , wherein said mixture contains a solvent which softens or partially dissolves the previous applied layer of plastic skin.

12. A method of making a plastic skin as a surface cover for a part for the interior of a vehicle wherein the plastic skin includes an electric conducting path embedded therein; the plastic skin is composed of a plastic material; and, the electric conducting path is a mixture of said plastic material of said plastic skin and a conducting material, the method comprising the steps of:

first producing said conducting path by alternately applying a layer of plastic material, then a layer of said mixture and then again a layer of said plastic material and bonding said layer to a multi-layer conductor foil;

then cutting said conductor foil into strip-shaped conducting paths; and,

thereafter bonding said conducting paths to said plastic skin.

13. The method of claim 12 , wherein a plurality of plastic material layers and said mixture layer are bonded to a multi-layer conductor foil.

14. The method of claim 12 , wherein the bonding between said conducting path and said plastic skin takes place via plastification of the bonding boundaries.

15. The plastic skin of claim 1 , wherein said plastic skin is a heatable covering material for vehicle seats.
