Abstract

The invention relates to a sealing arrangement for a vehicle window. The sealing arrangement comprises a retaining rail having a latching channel that is formed by a guide rail and a spring leg having a latch hook, the retaining rail being affixed to a window pane. The sealing arrangement further comprises a cover having a guide channel that is formed by a positioning stop and by a latching rail having a locking element. The guide rail is arranged in the guide channel and the latching rail is arranged in the latching channel, wherein the latch hook is engaged with the locking element in that a convex curved latching guide surface of the latch hook is guided along a latching sliding edge of the latching element, and a spring element is tensioned in the guide channel between the guide rail and a contact surface on the underside of the cover.

First claim

1 .- 16 . (canceled)

17 . A sealing arrangement for a motor vehicle window pane, comprising:
a holding rail having a latching channel that is formed by a guide rail and a spring leg with a latch hook, wherein the holding rail is affixed on a window pane; and a cover having a guide channel that is formed by a positioning stop and a latching rail having a locking element,
wherein the guide rail is arranged in the guide channel, and the latching rail is arranged in the latching channel,
wherein the latch hook is arranged on the locking element, such that a convexly curved engagement guide surface of the latch hook is guided along an engagement sliding edge of the locking element,
wherein a spring element is tensioned in the guide channel between a contact surface on the underside of the cover and the guide rail, and
wherein the convexly curved engagement guide surface has a local radius of curvature r EF of 1.5*b to 5.0*b, where b is a maximum deflection of the latch hook.

18 . The sealing arrangement according to claim 17 , wherein the convexly curved engagement guide surface is arranged in a distal region of the latch hook facing the locking element.

19 . The sealing arrangement according to claim 17 , wherein the convexly curved engagement guide surface has a local radius of curvature r EF of 2.0*b to 4.0*b.

20 . The sealing arrangement according to claim 17 , wherein the local radius of curvature of the convexly curved engagement guide surface is constant.

21 . The sealing arrangement according to claim 17 , wherein the engagement sliding edge has a radius of curvature r EG of 0.05*b to 0.5*b.

22 . The sealing arrangement according to claim 17 , wherein the engagement sliding edge has a radius of curvature r EG of 0.2*b to 0.4*b.

23 . The sealing arrangement according to claim 17 , wherein the spring leg is deflectable.

24 . The sealing arrangement according to claim 17 , wherein the spring leg is deflectably connected to the holding rail and the latching rail is rigid.

25 . The sealing arrangement according to claim 17 , wherein the locking element includes an unlatching guide surface with a first section with the contour of an inclined plane and a second section with a convexly curved contour.

26 . The sealing arrangement according to claim 25 , wherein a latching angle γ between the first section and a release direction is less than arctan(1/μ 0 ), where μ 0 is the coefficient of friction between the latch hook and the locking element.

27 . The sealing arrangement according to claim 26 , wherein the latching angle γ is from 62° to 85°.

28 . The sealing arrangement according to claim 25 , wherein the second section has a local radius of curvature r AF of 0.5*b to 5.0*b.

29 . The sealing arrangement according to claim 25 , wherein the second section has a local radius of curvature r AF of 1.0*b to 3.0*b.

30 . The sealing arrangement according to claim 25 , wherein the second section has a constant radius of curvature r AF of 0.5*b to 5.0*b.

31 . The sealing arrangement according to claim 25 , wherein the second section has a constant radius of curvature r AF of 1.0*b to 3.0*b.

32 . The sealing arrangement according to claim 25 , wherein the length of the first section is from 20% to 80% of the length of the unlatching guide surface.

33 . The sealing arrangement according to claim 25 , wherein the length of the first section is from 40% to 60% of the length of the unlatching guide surface.

34 . The sealing arrangement according to claim 17 , wherein the spring element is implemented, in cross-section, as a single lip and, together with the guide rail, seals and supports the contact surface on the underside of the cover between the positioning stop and the latching rail.

35 . A method-for producing a sealing arrangement, comprising:
bonding a holding rail to a pane via an adhesive bond; arranging a guide rail within a guide channel of a cover; pressing the cover having a latching rail into a latching channel beyond a latch hook under tensioning of a spring element between the guide rail and a contact surface on an underside of the cover, such that an engagement sliding edge of a locking element of the latching rail is guided along a convexly curved engagement guide surface of the latch hook; and relaxing the spring element so that that latching latch hook is engaged on the locking element of the latching rail.

36 . A method for releasing a sealing arrangement produced according to claim 35 , comprising guiding an unlatching a sliding edge of a latch hook along an inclined plane of a first section of an unlatching guide surface of the locking element, wherein the unlatching sliding edge is guided along a convexly curved contour of a second section of the unlatching guide surface.

37 . A method of using of a sealing arrangement according to claim 17 , comprising affixing the holding rail on a windshield or rear window.

38 . A method of using of a sealing arrangement according to claim 17 , comprising affixing the holding rail on a windshield, wherein the cover is configured as a water box.
