Abstract

A method of illuminating a component, having an outer skin layer, the method including the steps of: forming a seam of the outer skin layer; and locating an elongated light conducting medium in the seam.

First claim

What is claimed is:

1. A method of illuminating a component, comprising an outer surface layer, the method comprising:
forming a deck seam between at least two separate pieces of an outer skin layer, the deck seam having two join seams each joining two distinct portions of the at least two pieces together; and
locating an elongated light conducting medium in the deck seam between the two join seams, wherein tension control on one of the two join seams above the elongated light conducting medium provides a design gap located above the light conducting medium and between the at least two pieces so that the at least two pieces do not contact each other at the design gap and wherein light generated by the light conducting medium shows through the design gap, the design gap having a width between the at least two separate pieces at the one of the two join seams, and wherein the width of the design gap between the at least two separate pieces is smaller than a diameter of the elongated light conducting medium.

2. The method as in claim 1 , wherein the outer skin layer, is formed from the group consisting of vinyl, leather, cloth and thermoplastic polyolefin (TPO) and other man made or natural materials.

3. A component formed by the method of claim 2 , wherein the component is an interior trim piece of a vehicle.

4. The component of claim 3 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.

5. The method as in claim 1 , wherein the elongated light conducting medium is a side emitting fiber optic cable.

6. The method as in claim 1 , wherein the elongated light conducting medium is a side emitting fiber optic cable and a portion of at least one of the at least two separate pieces of the outer skin layer is folded back upon the at least one of the at least two separate pieces of the outer skin layer prior to the application of one of the two join seams, wherein at least one of the two join seams passes through a folded portion of the at least one of the at least two separate pieces of the outer skin layer.

7. The method as in claim 1 , wherein the elongated light is a side emitting fiber optic cable and wherein the outer skin layer, is formed from the group consisting of vinyl, leather, cloth and thermoplastic polyolefin (TPO).

8. A component formed by the method of claim 7 , wherein the component is an interior trim piece of a vehicle.

9. The component of claim 8 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.

10. The method as in claim 1 , wherein the elongated light conducting medium is inserted into the seam after the seam is formed.

11. The method as in claim 10 , wherein the elongated light conducting medium is coextruded with a supporting structure and wherein the outer skin layer, is formed from the group consisting of vinyl, leather, cloth and thermoplastic polyolefin (TPO).

12. A component formed by the method of claim 11 , wherein the component is an interior trim piece of a vehicle.

13. The component of claim 12 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.

14. A component formed by the method of claim 11 , wherein the elongated light conducting medium is electrically coupled to a vehicle function such that a light intensity and color of the elongated light conducting medium can be varied.

15. The component of claim 14 wherein the vehicle function is selected from the group comprising: turn signal indicators, music volume, vehicle speed, engine RPM and/or acceleration and combinations thereof.

16. The method as in claim 1 , wherein the elongated light conducting medium is sewn into the seam at the same time the seam is formed.

17. The method as in claim 16 , wherein the elongated light conducting medium is a side emitting fiber optic cable and wherein the outer skin layer, is formed from the group consisting of vinyl, leather, cloth and thermoplastic polyolefin (TPO).

18. A component formed by the method of claim 17 , wherein the component is an interior trim piece of a vehicle.

19. The component of claim 18 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.

20. The component of claim 19 , wherein the elongated light conducting medium is electrically coupled to a vehicle function such that a light intensity and color of the elongated light conducting medium can be varied and wherein the vehicle function is selected from the group comprising: turn signal indicators, music volume, vehicle speed, engine RPM and/or acceleration and combinations thereof.
