Abstract

A trim element, including: a flexible layer; a carrier, the flexible layer being secured to the carrier, the flexible layer comprising an outer show surface layer, a translucent layer and a light source, the light source being secured to a side of the translucent layer that is opposite to a side of the translucent layer secured to the outer show surface layer, the outer show surface layer being translucent; and a masking layer located between the outer show surface layer and the translucent layer, the masking layer having gaps where no masking layer is located between the outer show surface layer and the translucent layer.

First claim

What is claimed is:

1. A trim element, comprising: a flexible layer;
a carrier, the flexible layer being secured to the carrier, the flexible layer comprising an outer show surface layer, a translucent layer and a light source, the light source being secured to a side of the translucent layer that is opposite to a side of the translucent layer secured to the outer show surface layer, the outer show surface layer being translucent;
a masking layer located between the outer show surface layer and the translucent layer, the masking layer having gaps where no masking layer is located between the outer show surface layer and the translucent layer; and
switches, the switches being located between the masking layer and the translucent layer and wherein the switches are located behind or on top of the masking layer and are not located in the gaps.

2. The trim element as in claim 1 , further comprising printed electronics for heating the outer show surface layer, the printed electronics being located between the masking layer and the translucent layer.

3. The trim element as in claim 2 , wherein the printed electronics for heating the outer show surface layer are located behind or on top of the masking layer and are not located in the gaps.

4. The trim element as in claim 2 , wherein at least some of the switches control the printed electronics for heating the outer show surface layer.

5. The trim element as in claim 1 , wherein the switches are capacitive sensor elements.

6. The trim element as in claim 1 , wherein the light source is a plurality of light emitting diodes (LEDs).

7. The trim element as in claim 1 , wherein the translucent layer is a translucent foam.

8. The trim element as in claim 1 , wherein the outer show surface layer is a skin formed from a thermoplastic polyolefin (TPO).

9. The trim element as in claim 1 , wherein the light source is a plurality of light emitting diodes (LEDs), the translucent layer is a translucent foam, and the outer show surface layer is a skin formed from a thermoplastic polyolefin (TPO).

10. The trim element as in claim 4 , wherein the light source is a plurality of light emitting diodes (LEDs), the translucent layer is a translucent foam, and the outer show surface layer is a skin formed from a thermoplastic polyolefin (TPO).

11. The trim element as in claim 1 , further comprising microswitches or snap dome switches secured adjacent to the light source.

12. The trim element as in claim 1 , wherein traces for the light source and contact pads are printed on the carrier or applied via transfer layer.

13. The trim element as in claim 1 , wherein the outer show surface layer is a translucent skin formed from one of the following: a thermoplastic polyolefin (TPO), foil, artificial leather, leather or textile.

14. A method of forming a trim element, comprising:
securing a flexible layer to a carrier, the flexible layer comprising an outer show surface layer, a translucent layer and a light source, the light source being secured to a side of the translucent layer that is opposite to a side of the translucent layer secured to the outer show surface layer, the outer show surface layer being translucent; and a masking layer being located between the outer show surface layer and the translucent layer, the masking layer having gaps where no masking layer is located between the outer show surface layer and the translucent layer; and switches, the switches being located between the masking layer and the translucent layer and wherein the switches are located behind or on top of the masking layer and are not located in the gaps.

15. The method as in claim 14 , further comprising printed electronics for heating the outer show surface layer, the printed electronics being located between the masking layer and the translucent layer.

16. The method as in claim 15 , wherein the printed electronics for heating the outer show surface layer are located behind or on top of the masking layer and are not located in the gaps.

17. The method as in claim 15 , wherein at least some of the switches control the printed electronics for heating the outer show surface layer.

18. The method as in claim 14 , wherein the outer show surface layer is a translucent skin formed from one of the following: a thermoplastic polyolefin (TPO), foil, artificial leather, leather or textile.

19. The method as in claim 14 , wherein the switches are capacitive sensor elements.

20. A trim element, comprising: a flexible layer;
a carrier, the flexible layer being secured to the carrier, the flexible layer comprising an outer show surface layer, a translucent layer and a light source, the light source being secured to a side of the translucent layer that is opposite to a side of the translucent layer secured to the outer show surface layer, the outer show surface layer being translucent;
a masking layer located between the outer show surface layer and the translucent layer, the masking layer having gaps where no masking layer is located between the outer show surface layer and the translucent layer; and
wherein the outer show surface layer has a plurality of hidden icons that are only visible from an exterior show surface of the outer show surface layer when they are illuminated by the light source.
