Abstract

A vehicle seat is provided having first and second trim panels having an outer appearance surface. An illumination trim portion separates the first and second trim panels. The illumination portion has a pocket formed of translucent material and has first and second lateral flaps disposed on opposite sides of a central tunnel. A first seam secures the illumination portion to the first trim panel and to the first lateral flap. A second seam secures the illumination portion to the second trim panel and to the second lateral flap. A light conducting strip is inserted in the central tunnel of the pocket. A light source is in communication with the light conducting strip. Light from the light source is visible through the translucent material of the central tunnel.

First claim

What is claimed is:

1. A trim component comprising:
a first trim panel and a second trim panel; and
a pocket for a light pipe positioned between the first and second trim panels;
wherein a first lateral edge of the pocket is secured to the first trim panel, and
wherein a second lateral edge of the pocket is secured to the second trim panel.

2. The trim component of claim 1 wherein the pocket is formed of a translucent material.

3. The trim component of claim 2 wherein the pocket comprises an upper material strip and a lower material strip, wherein the upper material strip is attached to the lower material strip along the first and second lateral edges thereby defining first and second lateral flaps.

4. The trim component of claim 3 wherein the pocket is woven to form the first and second lateral flaps and a channel defined between the first and second lateral flaps.

5. The trim component of claim 3 wherein the upper material strip is secured to the lower material strip along the first and second lateral flaps with adhesive.

6. The trim component of claim 1 wherein the first lateral edge of the pocket is sewn to the first trim panel along a first seam; and
wherein the second lateral edge of the pocket is sewn to the second trim panel along a second seam.

7. The trim component of claim 6 further comprising:
a first fold formed in the first trim panel and positioned adjacent the pocket;
a second fold formed in the second trim panel and positioned adjacent the pocket;
a third seam extending through two layers of the first trim panel and the first lateral edge of the pocket; and
a fourth seam extending through two layers of the second trim panel and the second lateral edge of the pocket,
wherein the first and second seams are concealed along an appearance surface of the first and second trim panels.

8. The trim component of claim 2 further comprising a light strip disposed in the pocket, wherein light from the light strip is illuminated through the translucent material.

9. The trim component of claim 2 wherein the pocket is formed of an upper material strip and a lower material strip, wherein at least the upper material strip is at formed of the translucent material.

10. A vehicle seat comprising a trim component according to claim 1 .

11. The vehicle seat of claim 10 further a light strip inserted in the pocket; and
a light source in communication with the light pipe, wherein light from the light source is visible through a material of the pocket.

12. The vehicle seat of claim 11 further comprising wherein the light source comprises a light emitting diode.

13. A method of forming a trim assembly, the method comprising:
forming a pocket with translucent material;
positioning the pocket between a first trim panel and a second trim panel;
attaching the first trim panel to a first lateral edge of the pocket; and
attaching the second trim panel and to a second lateral edge of the pocket.

14. The method of claim 13 further comprising inserting a light conductive strip in the pocket.

15. The method of claim 13 wherein the first lateral edge of the pocket is attached to the first trim panel along a first seam; and
wherein the second lateral edge of the pocket is attached to the second trim panel along a second seam.

16. The method of claim 15 further comprising:
folding the first and second trim panels;
sewing a third seam through two layers of the first trim panel and the first lateral edge of the pocket;
sewing a fourth seam through two layers of the second trim panel and the second lateral edge of the pocket, wherein the first and second seams are concealed along an appearance surface of the trim panels; and
inserting a light conductive strip in the pocket after sewing the first, second, third and fourth seams.

17. The method of claim 13 wherein forming the pocket comprises securing an upper material strip to a lower material strip along the first lateral edge and the second lateral edge, wherein at least the upper material strip is formed of the translucent material.

18. The method of claim 17 further comprising arranging the upper material strip formed of the translucent material adjacent an appearance surface of the first and second trim panels.

19. The method of claim 17 , wherein the upper material strip is attached to the lower material strip along first and second lateral edges thereby defining first and second lateral flaps that extend away from a central tunnel.

20. The method of claim 19 further comprising securing the upper material strip to the lower material strip along the first and second lateral flaps with adhesive.
