Abstract

An illuminating device for a vehicle includes a carrier module, a flat light guide attached to the carrier module with a plurality of emitting points, and multiple light sources for illuminating the light guide. The flat light guide is concealed with a translucent haptic layer, which is attached to a visible side of the light guide, which, in turn, is covered by a decorative layer. The illuminating device comprises a rope-like light guide, which has an inherent light source and is connected to the decorative layer via a retaining device. This therefore results in a flat arrangement, which can be easily integrated into the interior parts and simultaneously enables illumination over a large surface area. In doing so, additional light effects can be integrated by means of the rope-like light guide. The illuminating device is not visible while switched off, as the illuminating device is covered by the decorative layer.

First claim

What is claimed is:

1. An illuminating device for a vehicle comprising:
a carrier module;
a flat light guide having a plurality of emitting points, the flat light guide being attached to the carrier module;
multiple light sources for illuminating the flat light guide;
a translucent haptic layer is attached to a visible side of the flat light guide;
a decorative layer connected to the haptic layer; and
a rope-like light guide having a light source,
wherein a retaining device for the rope-like light guide is provided on the decorative layer.

2. The illuminating device according to claim 1 , wherein the rope-like light guide is an optical fiber inserted into a sheath, wherein the sheath is attached to the retaining device.

3. The illuminating device according to claim 2 , wherein the retaining device is formed from two seam edges of the decorative layer and the sheath is sewn to the seam edges.

4. The illuminating device according to claim 3 , wherein the seam edges have a width of approximately 3 mm.

5. The illuminating device according to claim 2 , wherein the sheath is a textile that contains plastic and is placed around the optical fiber to form a lug protruding from the optical fiber, is the lug being used by the retaining device for attachment.

6. The illuminating device according to claim 1 , wherein the translucent haptic layer is composed of several sections, a separating line of which runs along the rope-like light guide.

7. The illuminating device according to claim 1 , wherein the translucent haptic layer is a spacer fabric with transparent threads, wherein the thickness of the threads is between 1.5 and 5 mm.

8. The illuminating device according to claim 1 , wherein the decorative layer is leather having a thickness between 0.6 and 1 mm.

9. The illuminating device according to claim 1 , wherein the decorative layer defines a perforation, wherein the perforation starts at a distance from the retaining device of at least 5 mm.

10. The illuminating device according to claim 9 , wherein the perforation of the decorative layer has individual openings having a surface area of at least 0.2 mm 2 .

11. The illuminating device according to claim 10 , wherein the size of the openings is varied and decreases from a center of the illuminating device to edges of the illuminating device.

12. The illuminating device according to any of claim 9 , wherein the perforation is arranged such that an embellishment defines a sign.

13. The illuminating device according to claim 1 , wherein the emitting points are created in a surface of the flat light guide and a reflective layer is attached to the flat light guide on a side opposite the emitting points.

14. The illuminating device according to claim 1 , wherein the multiple light sources beam into a narrow side of the flat light guide.

15. The illuminating device according to claim 1 , wherein the carrier module is formed in a shape of a box and the multiple light sources are attached to the carrier module by means of press fitting.

16. The illuminating device claim 1 , wherein a light transmission element is arranged between the rope-like light guide and the light of the rope-like light guide.

17. The illuminating device according to claim 1 , wherein the flat light guide has at least one throughput through which the rope-like light guide is routed.

18. The illuminating device according to claim 1 , wherein multiple light sources are arranged on the rope-like light guide.

19. The illuminating device according to claim 18 , wherein the multiple light sources are arranged in a row.

20. The illuminating device according to claim 1 , wherein the carrier module has at least one recess through which the rope-like light guide is at least partially routed.

21. An interior part for a vehicle having a slot on a side panel, which opens a mounting space of the interior part, into which the illuminating device of claim 1 is inserted and attached.
