Abstract

The laminated glass panoramic roof is a popular although expensive option offered on a growing number of automobiles. Much of its appeal comes from the sleek modern appearance that it gives to the vehicle. The opaque laminated vehicle roof, by removing vision and optical requirements can be produced at a lower cost. The opaque laminated roof, by retaining a glass outer surface, maintains the same exterior appearance, aesthetic and much of the appeal of a conventional laminated glass panoramic roof. The opaque laminated vehicle roof also allows for the use of alternate materials which can further reduce cost and weight while adding additional features such as installation hardware, fasteners, lighting, antennas and solar cells to the roof.

First claim

What is claimed is:

1. An opaque laminated vehicle roof, comprising:
a first glass layer having first and second oppositely disposed major faces with the first major face of said first glass layer serving as an outer surface of the vehicle;
an additional layer, having first and second oppositely disposed major faces; and
a non-transparent adhesive layer having first and second oppositely disposed major faces, said at least one adhesive layer being positioned between and affixing opposite major surfaces of adjacent layers to each other;
wherein the additional layer is substantially made of glass, and
wherein the opacity of the opaque laminate is provided by the non-transparent adhesive layer.

2. The vehicle roof of claim 1 , further comprising a heat reflecting layer, a heat absorbing layer and/or a sound deadening layer.

3. The vehicle roof of claim 1 , further comprising a hard scratch resistant coating on the first major face of the first glass layer and/or an anti-reflective coating on the second major face of the first glass layer.

4. The vehicle roof of claim 1 further comprising at least one component selected from the group consisting of: an antenna, a light source and a solar cell.

5. A vehicle comprising the vehicle roof of claim 1 .

6. The vehicle roof of claim 1 , wherein the non-transparent adhesive layer is a black PBV.

7. An opaque laminated vehicle roof, comprising:
a first glass layer having first and second oppositely disposed major faces with the first major face of said first glass layer serving as an outer surface of the vehicle;
an additional layer, having first and second oppositely disposed major faces; and
an adhesive layer having first and second oppositely disposed major faces, said at least one adhesive layer being positioned between and affixing opposite major surfaces of adjacent layers to each other;
wherein the additional layer is a non-transparent glass layer comprising a paint layer; and
wherein the opacity of the opaque laminate is provided by the paint layer provided on a mayor surface of the glass.

8. The vehicle roof of claim 7 , further comprising a heat reflecting layer, a heat absorbing layer and/or a sound deadening layer.

9. The vehicle roof of claim 7 , further comprising an infrared reflecting layer which is selected from the group consisting of an infrared reflecting coating and an infrared reflecting film.

10. The vehicle roof of claim 7 , further comprising a hard scratch resistant coating on the first major face of the first glass layer and/or an anti-reflective coating on the second major face of the first glass layer.

11. The vehicle roof of claim 7 , wherein the paint layer is a black enamel frit paint layer.

12. . The vehicle roof of claim 7 , further comprising at least one component selected from the group consisting of: an antenna, a light source and a solar cell.

13. An opaque laminated vehicle roof, comprising:
a first glass layer having first and second oppositely disposed major faces with the first major face of said first glass layer serving as an outer surface of the vehicle;
an additional layer, having first and second oppositely disposed major faces; and
at least one adhesive layer having first and second oppositely disposed major faces, said at least one adhesive layer being positioned between and affixing opposite major surfaces of adjacent layers to each other;
wherein the opacity of the opaque laminate is provided by at least one of said layers, and
wherein said additional layer is substantially made using a material selected from the group consisting of: metal, steel, aluminum, steel alloy and carbon composite.

14. The vehicle roof of claim 13 , further comprising a second glass layer, wherein the second glass layer is disposed between the first glass layer and the additional layer, or wherein the additional layer is disposed between first and second glass layers.

15. The vehicle roof of claim 13 , further comprising a heat reflecting layer, a heat absorbing layer and/or a sound deadening layer.

16. The vehicle roof of claim 13 , wherein said additional layer comprises a metal or steel-based layer having an opening on it.

17. The vehicle roof of claim 13 , further comprising an infrared reflecting layer which is selected from the group consisting of an infrared reflecting coating and an infrared reflecting film.

18. The vehicle roof of claim 13 , further comprising a hard scratch resistant coating on the first major face of the first glass layer and/or an anti-reflective coating on the second major face of the first glass layer.

19. The vehicle roof of claim 13 , further comprising at least one component selected from the group consisting of: an antenna, a light source and a solar cell.

20. The vehicle roof of claim 13 , wherein the additional layer is extended beyond the edge of the first glass layer.
