Description

Technical Field

[0001] The invention relates to a window assembly having a movable window pane and to a vehicle having at least one such window assembly. Background Art

[0002] Known window glass assemblies with movable window glass for vehicles have many variations. Usually, the movable window glass is respectively arranged in a receiving groove of a vehicle door.

[0003] DE 10 2020 101 800 A1 discloses a passenger vehicle with a UV-C light source. For the purpose of improving the cleaning or disinfection of the vehicle interior of a passenger vehicle, at least one UV-C light source is provided in the roof region of the vehicle interior. The UV-C light source is movably arranged in the roof region and / or fixedly mounted on a movable receiving portion in the roof region.

[0004] It is also known to use special window coatings to clean or disinfect the interior air. By coating the inside of a vehicle window with, for example, a titanium oxide-based compound, a higher degree of cleanliness against biological pathogens such as viruses and bacteria, as well as fine dust and other components, can be achieved. However, titanium oxide coatings are not an option, as they not only break down unwanted substances but also, for example, rubber seals. This is not a problem with stationary windows, such as the front or rear windshield, because these do not move, and the seals can be prevented from breaking down by leaving corresponding window area free. However, this is not feasible with movable windows, because they are not always fully open or fully closed. If, for example, the movable window is only half-open, the rubber seals come into contact with the coated area of ​​the movable window and are attacked. Summary of the Invention

[0005] The object of the present invention is to provide a window assembly with a movable window pane and a vehicle with such a window assembly, which prevents a seal from coming into contact with the region of the movable window pane which is coated with a biocidal inner coating.

[0006] This object is achieved by a window pane assembly having the features of claim 1 and by a vehicle having the features of claim 10. Advantageous embodiments with expedient developments of the invention are specified in the dependent claims.

[0007] In order to provide a window glass assembly with a movable window glass, which prevents a seal from abutting against an area of ​​the movable window glass coated with a bactericidal inner coating, a connecting device is implemented, which connects at least one seal in a sealing manner to an uncoated area of ​​the window glass in the open position and in the closed position and allows the at least one seal to be lifted from the window glass during movement of the window glass and when the window glass is in a position between the open position and the closed position.

[0008] Furthermore, a vehicle having at least one such window pane assembly is proposed, wherein the at least one window pane assembly is arranged in a receiving groove of a vehicle door.

[0009] In the following, a window assembly with a movable window pane is understood to be an assembly in which the movable window pane has a biocidal inner coating. Furthermore, such a window assembly comprises a drive for moving the window pane between an open position and a closed position, and a sealing device having at least one seal for sealing the window pane.

[0010] As a disinfecting inner coating for window panes in vehicles, preferably a titanium dioxide-based compound can be used. Of course, other suitable materials can also be used to achieve a higher degree of cleanliness against biological pathogens such as viruses and bacteria as well as fine dust and other components in the interior.

[0011] By additionally coating the movable window panes in vehicles with a disinfecting compound, the effective disinfection surface for cleaning the interior air can be easily increased. By means of this coupling device, at least one seal of the movable window pane can be lifted off the surface of the window pane when the window pane is partially opened, so that when the seal lies above the window pane's inner coating, there is no longer any contact. If the window pane is fully opened or closed, the at least one seal again rests on the surface of the window pane, which does not have the antibacterial inner coating in the edge region.

[0012] In an advantageous embodiment of the window pane assembly, the coupling device can include a fixed lifting guide oriented parallel to the direction of movement of the window pane and a movably supported tie rod, the lifting guide being oriented parallel to the lifting guide in the unloaded state and being coupled to the lifting guide via a movable coupling element. This allows for a particularly simple and cost-effective implementation of the coupling device.

[0013] In another advantageous embodiment of the window assembly, the tie rod is rotatably supported at one end in the installation position and has a curved free end that is coupled to the at least one seal. The curved free end of the tie rod can preferably be coupled to the at least one seal via a spring element. The spring element causes the at least one seal to press against the surface of the window pane with a constant force in both the closed and open positions of the window pane.

[0014] In another advantageous embodiment of the window pane assembly, the stationary lifting guide can form a guide rail for the movable coupling element, said guide rail comprising a recess in the direction of the window pane at a first end position and a second end position for the movable coupling element. In this case, when the coupling element falls into one of the recesses, it can generate a tensile force, which causes the bent free end of the tie rod to pivot in the direction of the window pane, and when it is removed from the corresponding recess, it can generate a thrust, which causes the bent free end of the tie rod to pivot away from the window pane.

[0015] In another advantageous embodiment of the window pane assembly, the bent free end of the tie rod can move the at least one seal toward the window pane when the movable coupling element falls into one of the recesses and press the at least one seal sealingly against the corresponding uncoated area of ​​the window pane with a predeterminable force. Furthermore, the bent free end of the tie rod can lift the at least one seal from the window pane when the movable coupling element is removed from the corresponding recess.

[0016] In another advantageous design of the window glass assembly, the connecting element can be connected to the drive device of the window glass so that the connecting element is positioned in a first end position and a first recess of the guide rail when the window glass is in the closed position, and is positioned in a second end position and a second recess of the guide rail when the window glass is in the open position.

[0017] The advantages and preferred embodiments described for the window pane assembly according to the invention also apply to the vehicle according to the invention.

[0018] The features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description of the figures and / or shown individually in the figures may be used not only in the combination indicated in each case but also in other combinations or individually without departing from the scope of the present invention. Therefore, embodiments that are not explicitly shown or explained in the figures but are presented and can be produced by individual feature combinations from the explained embodiments are also to be considered as being included and disclosed by the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiments of the present invention are shown in the accompanying drawings and further described in the following description. In the accompanying drawings, the same reference numerals represent components or elements that perform the same or similar functions.

[0020] Figure 1 An embodiment of a vehicle according to the invention is shown in a schematic partial sectional view in the region of a door with a glazing assembly according to the invention;

[0021] Figure 2 Shown in a schematic cross-sectional view Figure 1 Embodiments of the sealing device of the window glass assembly according to the present invention. DETAILED DESCRIPTION

[0022] like Figure 1 As shown, a partial view of a vehicle according to the invention shows a vehicle door 1 with a window assembly 10 according to the invention. Here, the window assembly 10 is arranged in a receiving groove 7 of the vehicle door 1, which is delimited by the outer panel 3 and the inner panel 5 of the vehicle door 1. As can also be seen from Figure 1 As can be seen in FIG, the window pane assembly 10 shown seals the inner panel 5 of the vehicle door 1 against the window pane 12 at the upper end of the receiving groove 7 .

[0023] As from Figure 1 and Figure 2 As can be further seen, the illustrated embodiment of the window pane assembly 10 according to the invention comprises a movable window pane 12 having a biocidal inner coating 14, a drive device 16 for moving the window pane 12 between an open position and a closed position, and a sealing device 20 comprising at least one seal 24 for sealing the window pane 12. A coupling device 30 seals the at least one seal 24 in the open position and in the closed position with the uncoated areas 12.1, 12.2 of the window pane 12. During movement of the window pane 12 and when the window pane 12 is in a position between the open position and the closed position, the coupling device 30 releases the at least one seal 24 from the window pane 12.

[0024] If you can also Figure 1 As can be seen in the figure, in the illustrated embodiment of the window pane assembly 10, the coupling device 30 comprises a fixed lifting guide 32, which is oriented parallel to the direction of movement of the window pane 12 in the receiving groove 7 of the vehicle door 1, and a movably supported tie rod 36. The tie rod is oriented parallel to the lifting guide in the unloaded state and is coupled to the lifting guide 32 via a movable coupling element 38. The lifting guide 32 is screwed to the vehicle door 1 at an upper mounting location 32.1 and a lower mounting location 32.2. Of course, other suitable fastening techniques can also be used to fasten the lifting guide 32.

[0025] like Figure 1 As further shown, in the illustrated embodiment of the window assembly 10, a tie rod 36 is pivotally supported at one end on the vehicle door at a mounting position 36.1 and has a curved free end 36.2, which is coupled to at least one seal 24. A fixed lifting guide 32 forms a guide rail 35 for a movable coupling element 38. The guide rail has recesses 35.1 and 35.2, respectively, facing the window pane 12, at a first end position 34A and a second end position 34B for the movable coupling element 38. When the coupling element 38 is inserted into one of the recesses 35.1 and 35.2, it moves the curved free end 36.2 of the tie rod 36 toward the window pane 12. When it is removed from the respective recess 35.1 and 35.2, the coupling element 38 moves the curved free end 36.2 of the tie rod 36 away from the window pane 12. The pivoting position of the rotatably supported tie rod 36 and thus also the position of the at least one seal 34 is adjusted by means of the lifting guide 32 and the coupling element 38. Since the tie rod 36 is rotatably supported at the installation position 36.1, a tensile force acts on the tie rod 36 when the movable coupling element 38 falls into one of the recesses 35.1, 35.2. This tensile force causes the bent free end 36.2 of the tie rod 36 to pivot in the direction of the window pane 12, so that the free end 36.2 of the tie rod 36 presses the at least one seal 24 sealingly against the corresponding uncoated areas 12.1, 12.2 of the window pane 12 with a predeterminable force. Figure 1 As can be seen in FIG, a first unpainted area 12.1 of the window pane 12 is formed at the upper edge of the window pane 12. A second unpainted area 12.2 is formed at the lower edge of the window pane 12. When the movable coupling element 38 is moved out of the corresponding recesses 35.1, 35.2, a thrust acts on the tie rod 36, which causes the bent free end 36.2 of the tie rod 36 to swing away from the window pane 12, so that the bent free end 36.2 of the tie rod 36 lifts the at least one seal 24 from the window pane 12.

[0026] If you can also Figure 1As can be seen in the figure, the coupling element 38 is coupled to the drive 16 of the window pane 12 via an operative connection, shown in dashed lines, such that when the window pane 12 is in the closed position, the coupling element 38 is positioned in a first end position 34A and in a first recess 35.1 of the guide rail 35. When the window pane 12 is in the open position, the coupling element 38 is positioned in a second end position 34B and in a second recess 35.2 of the guide rail 35. When the window pane 12 is between the closed and open positions, the drive 16 moves the window pane 12 vertically downward in the negative z-direction, wherein the coupling element 38, starting from the first end position 34A, moves in the negative z-direction from the first recess 35.1 toward the second recess 35.2. When the window pane 12 is between the open and closed positions, the drive 16 moves the panel 12 vertically upward in the positive z-direction, wherein the coupling element 38, starting from the second end position 34B, moves in the positive z-direction from the second recess 35.2 toward the first recess 35.1. In the illustrated embodiment, the coupling element 38 comprises a coupling rod 38.1, with a plurality of guide rollers 38.2 and 38.3 disposed at each end. A first guide roller 38.2 is coupled to the lifting guide 32 at the first end of the coupling rod 38.1 and rolls thereon. A second guide roller 38.3, at the second end of the coupling rod 38.1, is coupled to the tie rod 36 and rolls thereon. In the illustrated embodiment, two first guide rollers 38.2 are disposed on either side of the lifting guide 32, and two second guide rollers 38.3 are disposed on either side of the tie rod 36. Furthermore, the coupling rod 38.1 is coupled to the drive 16.

[0027] If you can also Figure 2 As can be seen in the figure, in the illustrated embodiment, the free end 36.2 of the tie rod 36 is coupled to the at least one seal 24 via the spring element 26. In this case, the at least one seal 24 (embodied as a sealing rubber 24A in the illustrated embodiment), the spring element 26, and the free end 36.2 of the tie rod 36 are at least partially received in the seal receiver 22, which in the illustrated embodiment is embodied as a sleeve. The wall of the seal receiver 22 guides the seal 24 and the free end 36.2 of the tie rod 36 when moving toward and away from the window pane 12.
