Abstract

A sealing arrangement for vehicle windows is described. The sealing arrangement has at least a holding rail that has a locking channel, which is formed by a guide rail and a resilient leg, and is fastened to a window and a cover that has a guide channel, which is formed by a locking rail and a positioning stop. The guide rail is arranged in the guide channel and the locking rail is latched in the locking channel. A locking hook is latched onto the resilient leg in a projecting region of the locking rail and a resilient element is clamped in the guide channel between a stop face on the underside of the cover and the guide rail.

Claims

1. A sealing arrangement for a motor vehicle pane, comprising at least:

a holding rail having a locking channel that is formed by a guide rail and a resilient leg, wherein the holding rail is fastened to a pane, and

a cover having a guide channel that is formed by a locking rail and a positioning stop, wherein

the guide rail is arranged in the guide channel and the locking rail is latched in the locking channel, wherein a locking hook is arranged on the resilient leg in a projecting region of the locking rail, and

a resilient element is clamped in the guide channel between a stop face on the underside of the cover and the guide rail.

2. The sealing arrangement according to claim 1, wherein the resilient element is connected to the guide rail or to the stop face.

3. The sealing arrangement according to claim 1, wherein the resilient element is implemented as a solid material, as a hollow chamber profile, or as a U-shaped profile.

4. The sealing arrangement according to claim 1, wherein the resilient element contains elastomers, thermoplastic elastomers, and preferably ethylene propylene diene rubber, styrene butadiene rubber, polybutadiene rubber, nitrile rubber, chloroprene rubber, fluorinated rubber, silicone rubber, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, copolymers, and/or mixtures thereof.

5. The sealing arrangement according to claim 1, wherein the guide channel has at least one assembly stop.

6. The sealing arrangement according to claim 1, wherein the resilient leg is deflectable or is deflectably connected to the holding rail.

7. The sealing arrangement according to claim 1, wherein the resilient leg has, in the region provided for the deflection, a thickness of 0.2 mm to 1 mm.

8. The sealing arrangement according to claim 1, wherein an angle between the positioning stop and the perpendicular to the stop face is from 0°

to 45°

.

9. The sealing arrangement according to claim 1, wherein the holding rail and/or the guide rail contains at least one reinforcement insert.

10. The sealing arrangement according to claim 1, wherein, in the region provided for the deflection, the resilient leg contains a metal foil or is preferably made from a metal foil.

11. The sealing arrangement according to claim 1, wherein the locking rail has, in subsections, recesses and/or, in subsections, no projecting regions.

12. The sealing arrangement according to claim 5, wherein the guide channel has three to seven assembly stops.

13. The sealing arrangement according to claim 5, wherein the angle between the positioning stop and the perpendicular to the stop face is from 2°

to 25°

.

14. A method for producing the sealing arrangement according to claim 1, comprising:

a) durably bonding the holding rail to the pane by an adhesive connection,

b) introducing the guide rail of the cover into the guide channel of the holding rail, and creating a defined distance between the rear edge of the cover and the bottom edge of the pane,

c) pressing the cover with the locking rail into the locking channel beyond the locking hook under tensioning of the resilient element between the guide rail and the stop face on the underside of the cover,

d) moving the cover back under relaxation of the resilient element and latching the locking hook into the projecting region of the locking rail.

15. The method according to claim 14, wherein in step (b) the guide rail is guided along on an assembly stop.

16. The method according to claim 14, wherein the cover is connected, in segments, to the holding rail.

17. A method comprising:

providing the sealing arrangement according to claim 1, and using the sealing arrangement in a motor vehicle pane.

18. The method according to claim 17, wherein the motor vehicle pane is chosen from a windshield or a rear window.

19. The method according to claim 17 wherein the cover is a water draining chamber cover.
