Abstract

A roof rail assembly ( 10 ) including at least one stanchion portion ( 12 ) having a cover ( 14 ) and at least one lighting device ( 16 ). A light permeable film ( 22 ) provides a predetermined surface appearance and/or design and is translucent to allow light from the lighting device ( 16 ) to pass through under predetermined conditions. When the lighting device ( 16 ) is not illuminating, the light permeable film ( 22 ) provides a predetermined surface appearance. The film ( 22 ) is operatively translucent when the lighting source ( 16 ) is illuminated and additionally provides a predetermined design appearance when backlit. The selective lighting on the stanchions of the roof rails ( 18 ) provides illumination and a higher location of the indicator of unlock for easier location of a vehicle at greater distances.

First claim

What is claimed is:

1 . A roof rail assembly for a vehicle, comprising:
a plurality of mounting portions attached to a vehicle arranged to allow stowing of cargo; at least one roof rail coupled to said plurality of mounting portions; a stanchion portion coupled to each end of said at least one roof rail and having a cover; at least one lighting device; a lens to direct illumination of said at least one lighting device; and a film which provides a predetermined surface appearance on said stanchion portion when the at least one lighting device is not actuated and which allows light to pass through the film under predetermined conditions upon illumination of said at least one lighting device.

2 . The roof rail assembly of claim 1 , wherein said film covers the entire stanchion portion.

3 . The roof rail assembly of claim 1 , wherein said film is captured in said cover and located over an area of said lens.

4 . The roof rail assembly of claim 1 , wherein said film is part of a lighting module assembly, said lighting module assembly rear mounted into an opening in said cover.

5 . The roof rail assembly of claim 1 , wherein said film is formed of a material with a chrome appearance and is translucent for light transmission upon illumination of said at least one lighting device.

6 . The roof rail assembly of claim 5 , wherein said film has a predetermined printed design on the back side of said film suitable to provide a desired surface appearance when backlit by said at least one lighting device.

7 . The roof rail assembly of claim 5 , wherein said film has a predetermined design provided by a two shot molding process to achieve said predetermined surface appearance when backlit by said at least one lighting device.

8 . The roof rail assembly of claim 1 , wherein said film is back injected with a light transmissive plastic material.

9 . The roof rail assembly of claim 1 , wherein said film is back injected with a light transmissive plastic material, said light transmissive plastic material selected from the group consisting of acrylonitrile butadiene styrene (ABS) or a transparent polycarbonate (PC) and poly(methyl methacrylate) (PMMA), to complete the lens.

10 . The roof rail assembly of claim 1 , wherein said cover is a plastic molded cover with an opening to receive said lens.

11 . The roof rail assembly of claim 1 , wherein said stanchion portion further comprises a printed circuit (PC) board, where said PC, lens, and said at least one lighting source form a lighting module assembly housed within said cover.

12 . The roof rail assembly of claim 11 , wherein said lighting module assembly is mounted within an inner opening of said cover adjacent to said film.

13 . The roof rail assembly of claim 11 , wherein said film is part of said lighting module assembly, said lighting module assembly is rear mounted into an opening of said cover.

14 . The roof rail assembly of claim 1 , wherein said at least one lighting device is connected to the back side of said lens.

15 . The roof rail assembly of claim 1 , wherein said at least one lighting device is selected from the group consisting of light emitting diodes, surface mounted light emitting diodes to a printed circuit board, fiber optics, sheet form fiber optics, molded acrylic light piping part, and combinations thereof.

16 . A roof rail assembly for a vehicle roof, comprising:
a plurality of mounting portions attached to a vehicle arranged to allow stowing of cargo; at least one roof rail coupled to said plurality of mounting portions; a stanchion portion coupled to each end of said at least one roof rail and having a cover, at least one lighting module assembly including at least one lighting device, a lens to direct illumination of said at least one lighting device; and a film; wherein the film provides a predetermined surface appearance on said stanchion portion when the at least one lighting device is not actuated and which allows light to pass through the film under predetermined conditions upon illumination of said at least one lighting device.

17 . The roof rail assembly for a vehicle roof of claim 16 , wherein said film covers the entire stanchion portion.

18 . The roof rail assembly of claim 16 , wherein and edge of said film is captured in said cover during molding and said lighting module assembly is rear mounted within an inner opening of said cover such that said lens is in abutting engagement with the back side of said film.

19 . The roof rail assembly of claim 16 , wherein said film is part of said lighting module assembly and said lighting module assembly is rear mounted into an opening formed in said cover.

20 . A roof rail assembly for a vehicle roof, comprising:
a plurality of mounting portions attached to a vehicle arranged to allow stowing of cargo; at least one roof rail coupled to said plurality of mounting portions; a stanchion portion coupled to each end of said at least one roof rail and having a cover and at least one lighting module assembly including at least one lighting device; a lens to direct illumination of said at least one lighting device; and a film back injected with a light transmissive plastic material, where the stanchion portion provides a predetermined surface appearance when the at least one lighting device is not actuated and which allows light to pass through the film under predetermined conditions upon illumination of said at least one lighting device.
