Abstract

A motor vehicle window pane with antenna mount is described. The motor vehicle window pane with antenna mount has an opening in a composite pane made of an outer pane, an intermediate layer, and an inner pane. An adhesive is disposed on the outer pane on a top in a region around the opening. A mounting plate is fixed on the adhesive. An antenna housing is disposed on the mounting plate and has a rod-shaped antenna mount within the opening and below a recess.

Claims

1. A vehicle window pane with antenna mount, comprising:

an opening in a composite pane, the composite pane being made of an outer pane, an intermediate layer, and an inner pane, wherein the inner pane has a recess adjacent the opening,

an adhesive disposed on the outer pane on a top of a region around the opening, wherein the adhesive is more expansive than the opening of the inner pane, and a mounting plate disposed and fixed on the adhesive,

an antenna housing on the mounting plate, wherein the antenna housing comprises a rod-shaped antenna mount within the opening as well as within and/or below the recess and is reversibly detachably fixed on the mounting plate, and

a nut or a clip on the rod-shaped antenna mount, which fixes the antenna housing on the mounting plate.

2. The vehicle window pane according to claim 1, wherein a sealing ring and a supporting ring are disposed in the opening within the recess.

3. The vehicle window pane according to claim 1, wherein the adhesive is surrounded by an outer sealing ring.

4. The vehicle window pane according to claim 1, wherein the opening has a diameter of 0.2 cm to 5 cm.

5. The vehicle window pane according to claim 1, wherein the composite pane contains glass, polymers, or mixtures thereof.

6. The vehicle window pane according to claim 1, wherein the adhesive contains adhesives, moisture-reactive hot-melt adhesives or heat-curing adhesive.

7. The vehicle window pane according to claim 2, wherein the mounting plate, the supporting ring, or the mounting plate and the supporting ring contain metal, polymers or metal and polymers.

8. The vehicle window pane according to claim 1, wherein the rod-shaped antenna mount, clip, and/or nut contain metal, polymers, or metal and polymers.

9. A method comprising:

using the vehicle window pane according to claim 1 as a roof panel of a motor vehicle.

10. The vehicle window pane according to claim 4, wherein the opening has a diameter of 1 cm to 2 cm.

11. The vehicle window pane according to claim 5, wherein the glass is flat glass, float glass, quartz glass, borosilicate glass or soda-lime glass.

12. The vehicle window pane according to claim 5, wherein the polymer is polyethylene, polypropylene, polycarbonate or polymethyl methacrylate.

13. The vehicle window pane according to claim 6, wherein the adhesive is polyurethane prepolymers, polyesters, polyolefins, polyurethanes, silicones, polyacrylates, polyvinyl acetates, polyepoxides, and/or polyamides, as well as mixtures and/or copolymers thereof.

14. The vehicle window pane according to claim 13, wherein the adhesive is polyurethane.

15. The vehicle window pane according to claim 7, wherein the metal is iron, manganese, chromium, nickel, cobalt, aluminum, vanadium, tungsten, titanium or alloys thereof.

16. The vehicle window pane according to claim 7, wherein the polymer is polyethylene, polypropylene, polystyrene, polyurethanes, polycarbonates, polymethyl methacrylates, polyacrylates, polyesters, polyamides, polyethylene terephthalate, polybutylene terephthalate, and/or mixtures or copolymers thereof.

17. The vehicle window pane according to claim 8 wherein the metal is iron, manganese, chromium, nickel, cobalt, aluminum, vanadium, tungsten, titanium, or alloys thereof.

18. The vehicle window pane according to claim 8 wherein the polymer is polyethylene, polypropylene, polystyrene, polyurethanes, polycarbonates, polymethyl methacrylates, polyacrylates, polyesters, polyamides, polyethylene terephthalate, polybutylene terephthalate, and/or mixtures or copolymers thereof.

19. A method for producing a vehicle window pane with antenna mount comprising:

drilling and/or cutting an opening in a composite pane made of an outer pane, an intermediate layer, and an inner pane, wherein the inner pane is provided with a recess,

applying an adhesive above the opening on the outer pane, wherein the adhesive is more expansive than the opening of the inner pane,

applying a mounting plate on the adhesive,

installing an antenna housing with an antenna mount on the mounting plate, wherein the antenna mount is guided through the opening, and

fixing the antenna housing on the mounting plate via the antenna mount with a nut or a clip below or in the recess.

20. The method according to claim 19, wherein an intermediate space between the mounting plate, the adhesive, and the outer pane of the composite pane is sealed with a sealing ring.

21. A method for producing a vehicle window pane with antenna mount, comprising:

drilling and/or cutting an opening in a composite pane made of an outer pane, an intermediate layer, and an inner pane, wherein the inner pane is provided with a recess,

applying an adhesive on a mounting plate, wherein the adhesive is more expansive than the opening of the inner pane,

applying the mounting plate above the opening on the outer pane,

placing the adhesive between the mounting plate and the outer pane,

installing an antenna housing with an antenna mount on the mounting plate, wherein the antenna mount is guided through the opening, and

fixing the antenna housing on the mounting plate via the antenna mount with a nut or a clip below or in the recess.

22. The method according to claim 21, wherein an intermediate space between the mounting plate, the adhesive, and the outer pane of the composite pane is sealed with a sealing ring.
