Abstract

In a mirror comprising a transparent glass plate provided at least partly with a rear-side reflecting coating as well as at least one integrated electrical means, the first glass plate comprises transparent and/or half-reflecting portions, the first glass plate is bonded to a second glass plate with the aid of a transparent adhesive layer in the form of a laminated glass pane, and electrical cal means are mounted in portions on an electrically conducting coating of the second glass plate facing the transparent and/or half-reflecting portions of the first glass plate.

Claims

1. A mirror (1) comprising a first transparent glass plate (4) having a viewing side and an opposite rear side, said first transparent glass plate (4) being at least partly provided on the rear side thereof with a reflecting coating (2) and at least one integrated electrical means (6), the first glass plate (4) including at least one of transparent and half-reflecting portions (8) on said rear side, the first glass plate (4) being bonded to a second glass plate (10) by a transparent adhesive layer (12) in the form of a laminated glass pane, said electrical means (6) being mounted on an electrically conducting coating (14) located on a surface of the second glass plate (10) facing the first glass plate (4) and in positions opposite the at least one of transparent and half-reflecting portions (8) of the first glass plate (4), the electrically conducting coating (14) being divided into a plurality of conductor paths (16) which are separated from each other by isolation paths (18), and the electrical means (6) being at least partially embedded in the transparent adhesive layer (12).

2. The mirror as defined in claim 1 wherein the electrically conducting coating (14) is a pyrolytically applied layer.

3. The mirror as defined in claim 1 wherein the electrically conducting coating (14) is arranged substantially across the overall surface on the side of the second glass plate (10) facing the first glass plate (4).

4. The mirror as defined in claim 1 wherein the electrically conducting coating (14) is configured at least on part of the surface of the second glass plate (10) as a heating surface (20).

5. The mirror as defined in claim 1 wherein a border region between the first and second glass plates (4, 10) is sealed by a circumferential seal (22).

6. The mirror as defined in claim 1 wherein the electrical means (6) includes one of illuminating, switching and displaying means.

7. The mirror as defined in claim 6 wherein the illuminating means is a light-emitting diode (6).

8. The mirror as defined in claim 6 wherein the switching means is a photo cell (24).

9. The mirror as defined in claim 6 wherein the displaying means is one of at least a flat screen and a light-emitting diode field.

10. The mirror defined in claim 1 wherein the two glass plates (4, 10) and the adhesive layer (12) collectively define a thickness of the mirror substantially 8 to 15 mm.

11. The mirror defined in claim 1 wherein the two glass plates (4, 10) and the adhesive layer (12) collectively define a thickness of the mirror substantially 10 to 12 mm.
