Abstract

A heated window with an electrically conducting surface coating that may be electrically connected as a heating element to a voltage source using a first and a second current-collecting rail and that is split into a first part, a heated look-through region, and a second part, an additional heated region. In the heated window at least two current-collecting rails are arranged in the additional heated region so that the direction in which the current flows in the additional heated region is roughly perpendicular to the direction in which the current flows in the heated look-through region.

Claims

1. A heated window comprising:

an electrically conducting surface coating configured to be electrically connected as a heating element to a voltage source using a first and a second current-conducting rail and which is split into a first part and a second part; and

at least two other current-conducting rails arranged in the first part, at least one current-conducting rail being electrically connected to the second current-conducting rail splitting the two parts and being roughly perpendicular to said second current-conducting rail, and at least one other current-conducting rail arranged from a first end to a second end towards the second current-conducting rail splitting the parts without entering in contact with the second current conducting rail.

2. The heated window as claimed in claim 1, wherein the second current-conducting rail and at least one other roughly perpendicular current-conducting rail are electrically connected together to form a common current input to the second part and the first part.

3. The heated window as claimed in claim 1, wherein at least one additional current-conducting rail is arranged roughly perpendicular to the second current-conducting rail without coming into electrical contact therewith.

4. The heated window as claimed in claim 1, wherein the first part is split into plural heated regions.

5. The heated window as claimed in claim 4, wherein the current-conducting rails arranged inside the first part act as a current-conducting rail common to two adjacent heated regions.

6. The heated window as claimed in claim 1, wherein the electrical circuits for the second part and the first part are connected to power sources at a same voltage.

7. Heated window as claimed in claim 1, wherein the first part is, at least in regions, electrically separated from the second part by a separating line.

8. The heated window as claimed in claim 7, wherein the separating line is produced by laser machining.

9. The heated window as claimed in claim 1, wherein the first part is protected against sight from an outside and/or from an inside by a colored layer.

10. The heated window as claimed in claim 1, wherein the heated window is provided with a colored layer in a form of a surround.

11. The heated window as claimed in claim 1, wherein the heated window is made as a laminated window.

12. The heated window as claimed in claim 11, wherein the laminated window includes two rigid panes, and a thermoplastic adhesive layer joining the two rigid panes together.

13. The heated window as claimed in claim 12, wherein the two rigid panes are glass panes.

14. A heated window comprising:

a first current-conducting rail extending only along one side of said window;

a second current-conducting rail extending parallel to said first current-conducting rail and dividing said window into a first part and a second part;

an electrically conducting surface coating configured to be electrically connected as a heating element to a voltage source connected between said first and second current-conducting rails; and

at least two other current-conducting rails arranged in the first part to be roughly perpendicular to the second current-conducting rail.

15. The heated window as claimed in claim 14, wherein the second current-conducting rail and at least one other roughly perpendicular current-conducting rail are electrically connected together to form a common current input to the second part and the first part.

16. The heated window as claimed in claim 14, wherein at least one additional current-conducting rail is arranged roughly perpendicular to the second current-conducting rail without coming into electrical contact therewith.

17. The heated window as claimed in claim 14, wherein the first part is split into plural heated regions.

18. The heated window as claimed in claim 17, wherein the current-conducting rails arranged inside the first part act as a current-conducting rail common to two adjacent heated regions.

19. The heated window as claimed in claim 14, wherein electrical circuits configured to provide current to heat the first part and the second part are connected to a same voltage.

20. The heated window as claimed in claim 14, wherein the first part is, at least in regions, electrically separated from the second part by a separating line.

21. The heated window as claimed in claim 20, wherein the separating line is produced by laser machining.

22. The heated window as claimed in claim 14, wherein the first part is protected against sight from an outside and/or from an inside by a colored layer.

23. The heated window as claimed in claim 14, wherein the heated window is provided with a colored layer in a form of a surround.

24. The heated window as claimed in claim 14, wherein the heated window is made as a laminated window.

25. The heated window as claimed in claim 24, wherein the laminated window includes two rigid panes, and a thermoplastic adhesive layer joining the two rigid panes together.

26. The heated window as claimed in claim 25, wherein the two rigid panes are glass panes.
