Description

[0001] The present invention relates to a motor vehicle door with a window recess and a window recess seal, and to a method for mounting a window recess seal to a motor vehicle door. Furthermore, the invention relates to a method for changing the position of a window pane in a window recess of a motor vehicle door.

[0002] To seal a door pane or window pane that lowers into a window recess of a vehicle door against the inner and outer walls of the vehicle door frame that define the window recess, profile seals made of ethylene propylene diene monomer (EPDM) rubber or a thermoplastic elastomer (TPE) are typically used on both the inside and outside of the window pane. These profile seals are usually fitted from above onto a vertical metal or plastic mounting flange on the inner or outer wall of the vehicle door frame. Clamping is achieved via an extruded metal or plastic carrier that stiffens the profile seals in the clamping area. Clamping lips further enhance adhesion to the mounting flange.

[0003] A disadvantage of a profile seal that is attached to a mounting flange is that a suitable mounting flange must be incorporated into the vehicle door frame. Another disadvantage is that, due to the mounting concept, such a profile seal is usually attached to the vehicle door frame from above and is therefore generally visible, which negatively impacts the aesthetics of the vehicle door. For this reason, trim strips are often used in addition to the profile seals to cover them and thus improve the appearance of the vehicle door. A further disadvantage of top-mounted profile seals is that, with this type of sealing concept, the vehicle door frame must be relatively far from the window pane in the area of ​​the window opening to allow for the profile seal to be mounted.

[0004] From DE 10 2022 111 445 A1, a sealing component for sealing a shaft in the body shell of a motor vehicle is known for lowering a vertically movable window pane. The sealing component comprises a sealing element made of an elastically deformable plastic with at least one sealing lip for sealing against the window pane and a rail made of a harder plastic connected to the sealing element.

[0005] The US 2023 / 0 118 935 A1, the US 2022 / 0 063 383 A1, the CN 2 03 623 347 U, the JP 2003 - 118 386 A and the US 3 029 481 A reveal further state of the art.

[0006] DE 43 18 685 A1 discloses a motor vehicle door with a window shaft seal that has the features of the preamble of claim 1. DE 10 2023 204 835 A1, DE 10 2015 014 819 A1, DE 10 2008 020 148 A1 and DE 196 27 652 A1 disclose further prior art.

[0007] The object of the present invention is to further develop a motor vehicle door having the features of the preamble of claim 1 in such a way as to facilitate its assembly. Furthermore, the invention provides a method for mounting a window channel seal to a motor vehicle door. Another method relates to a method for changing the position of a window pane in a window channel.

[0008] These tasks are solved by the subject matter of the independent claims. The dependent claims concern advantageous further training.

[0009] The vehicle door according to the invention has an outer wall and an inner wall, wherein the outer wall and the inner wall define a window recess. The vehicle door has a window pane, for example, a movable window pane, wherein the window pane can be moved into and out of the window recess, wherein the vehicle door has a window recess seal, wherein the window recess seal comprises a sealing element and a mounting rail for the sealing element, wherein the sealing element comprises a support component and an elastically deformable sealing component permanently connected to the support component, wherein the sealing element with its sealing component abuts the window pane in a sealing manner, and wherein the mounting rail is fixedly connected to the outer wall or to the inner wall.wherein the mounting rail has a retaining structure and the support component has a counter-structure designed complementary to the retaining structure, wherein the retaining structure and the counter-structure are in engagement with each other and designed such that the sealing element is displaceable along a longitudinal direction of the mounting rail relative to the mounting rail and the sealing element is held transversely to the longitudinal direction by a positive-locking interaction of the counter-structure with the retaining structure on the mounting rail.

[0010] This design allows for a different mounting concept for the window channel seal compared to a clip-on profile seal. Specifically, the mounting rail is initially fixed to the inner or outer wall without the sealing element being attached to the mounting rail. The sealing element is then attached to the vehicle door by sliding it into the mounting rail from one end along its length until it reaches the desired final position.

[0011] Unlike typical profile seals, which are attached to a mounting flange from above, the sealing element in the present invention can be inserted from the side for installation. The mounting flange otherwise required is therefore unnecessary. This allows the sealing element to be concealed from view while still being easily replaceable when needed, particularly without having to remove the window pane.

[0012] The solution according to the invention enables an exterior design of the vehicle door in which the window channel seal, in particular the sealing element, is not visible from the outside, without the need for an additional trim strip to cover the window channel seal. This eliminates the need for a trim strip, thereby saving components and assembly steps, and enabling new design concepts for the vehicle door body-in-white.

[0013] Preferably, the support component and / or the mounting rail are each dimensionally stable, for example, each made of a harder material than the sealing component. Particularly preferably, both the support component and the mounting rail are dimensionally stable. This enables or facilitates the insertion of the sealing element into the mounting rail along the longitudinal direction of the mounting rail, or the sliding of the mounting rail and the sealing element relative to each other along the longitudinal direction of the mounting rail. If, on the other hand, the support component were elastically deformable, as is intended for the sealing element, insertion or sliding would be difficult.Moving the sealing element along the longitudinal direction of the mounting rail is not possible or only possible with great difficulty, because its elastic deformability would cause the support component to deform, potentially leading to bulging in the area of ​​the counter-structure upon contact with the mounting rail, such as the retaining structure. This would hinder or significantly impede the movement. This is especially true if the mounting rail is curved, as is often the case or necessary with automotive door windows.

[0014] The dimensional stability of the mounting rail and / or the support component can be achieved, in particular, by making the mounting rail and / or the support component from a harder material than the sealing component. In this context, it is considered particularly advantageous if the sealing element has a soft component and a hard component, with the soft component forming the sealing component and the hard component forming the support component.

[0015] Regarding the dimensional stability of the support component, it is quite conceivable that the support component is still sufficiently bendable or flexible to be inserted into a curved mounting rail, but is less deformable than the sealing component.

[0016] The dimensional stability of the mounting rail can also be such that it is still sufficiently flexible or bendable to, for example, follow a curved course of the inner or outer wall.

[0017] However, for a stable mounting of the sealing element on the mounting rail, it is considered advantageous if the support component and the mounting rail are dimensionally stable to such an extent that the holding structure and the counter-structure can only be engaged and disengaged by inserting the sealing element into the mounting rail. This ensures a particularly secure hold of the sealing element on the mounting rail. The dimensional stability is such that it is not possible for the counter-structure to engage with the holding structure transversely to the longitudinal direction of the mounting rail, thus achieving a particularly secure hold transverse to the longitudinal direction of the mounting rail.Furthermore, when mounting the sealing element to the mounting rail, interlocking is considered disadvantageous compared to sliding it in, both in terms of assembly effort and potential automation of the assembly.

[0018] It is considered particularly advantageous if the support component consists of a first material with a first Shore hardness and the sealing component consists of a second material with a second Shore hardness, the first Shore hardness being greater than the second Shore hardness.

[0019] It is considered advantageous if the first material is a plastic, for example polypropylene (PP).

[0020] Furthermore, it is considered particularly advantageous if the second material is a second plastic, for example a thermoplastic elastomer (TPE) or an ethylene propylene diene monomer (EPDM) rubber.

[0021] In a further advantageous embodiment, the mounting rail is provided for to be made of a third material with a third Shore hardness. It is considered particularly advantageous if the third material is a third plastic, especially a fiber-reinforced plastic, for example glass fiber reinforced polypropylene (PPGF) or polyamide (PA).

[0022] It is considered particularly advantageous if the third Shore hardness is greater than or equal to the second Shore hardness.

[0023] However, it is also conceivable that the mounting rail and / or the support component are made of a metallic material.

[0024] Preferably, the holding structure and the counter-structure interact with some play. This facilitates movement and reduces the force required for movement.

[0025] Preferably, the sealing element is an extruded profile. This makes the manufacturing of the sealing element particularly cost-effective and simple.

[0026] It is considered particularly advantageous if the mounting rail is an injection-molded part.

[0027] In a particularly preferred embodiment, the support component and the sealing component are materially bonded together. It is conceivable that the support component and the sealing component are bonded together using adhesive. However, it is considered particularly advantageous if the support component and the sealing component are bonded together without adhesive. Adhesives have the disadvantage that, due to the fact that the sealing element is heavily exposed to environmental influences, they can exhibit signs of aging, which can adversely affect the service life of the sealing element.

[0028] Regarding the connection between the sealing component and the support component, it is quite conceivable that an intermediate component is formed between the support component and the sealing component, with the sealing component being connected to the support component via the intermediate component.

[0029] It is considered particularly advantageous if the intermediate component consists of a fourth material with a fourth Shore hardness, where the fourth Shore hardness is lower than the first Shore hardness and higher than the second Shore hardness. It has been shown that such a design of the Shore hardnesses of the sealing component, the support component, and the intermediate component results in a particularly long service life for the sealing element. It is assumed that, due to the aforementioned gradation of Shore hardnesses of the sealing component, the intermediate component, and the support component, shear stresses transferred to the sealing component during the movement of the window pane are partially absorbed by the intermediate component and only then transferred to the support component in a reduced form, thus preventing the sealing component from tearing away from the harder and therefore stiffer support component.

[0030] It is considered advantageous if the fourth material is a fourth plastic, for example a thermoplastic elastomer (TPE) or an ethylene propylene diene monomer (EPDM) rubber.

[0031] In a preferred embodiment, it is provided that the window pane is movable along or substantially along a vertical direction of the vehicle door.

[0032] In an advantageous embodiment, the sealing element, preferably in the area of ​​the support component, has one or more engagement structures, for example in the form of eyelets. These engagement structures can serve as points of engagement for a tool or aid for pulling the sealing element out of the mounting rail along the longitudinal direction of the mounting rail. The tool or aid can, for example, have a hook geometry that can be inserted into the engagement structure.

[0033] Preferably, the vehicle door is designed as a frameless vehicle door, so that the window pane, when extended, protrudes freely upwards from the vehicle door.

[0034] In a further advantageous embodiment, the mounting rail is curved such that its longitudinal direction has a curved profile. Accordingly, it is not essential that the mounting rail be straight.

[0035] In an advantageous further development, it is provided that the sealing component has at least one sealing lip, wherein the sealing component with the at least one sealing lip rests against the window pane.

[0036] It is quite conceivable that the sealing component, especially at least one sealing lip, is flocked, at least in some areas. Flocking can, for example, reduce the sliding friction between the sealing lip in the contact area with the window pane.

[0037] It is considered particularly advantageous if the sealing element, especially the sealing component, has a stop buffer for the sealing lip.

[0038] In an advantageous further development, it is provided that the mounting rail is permanently connected to the outer wall.

[0039] In such an embodiment, it is considered particularly advantageous if the outer wall has an upper edge, wherein the upper edge forms a visible edge of the vehicle door adjacent to the window recess, and wherein the window recess seal is arranged vertically below the upper edge in the window recess, with the upper edge projecting towards the window pane, preferably bent towards the window pane, such that the upper edge at least partially covers the window recess seal in the vertical direction. Such a design is considered particularly advantageous in that a sill trim to cover the window recess seal can be dispensed with, since the window recess seal is already covered by the upper edge of the outer wall and is therefore not visible from the outside.Due to the inventive design of the window shaft seal, the sealing element can still be easily removed if necessary, for example to replace it, without the need for a complex disassembly of the window pane.

[0040] It is considered particularly advantageous if the longitudinal direction runs transversely, especially perpendicularly, to the vertical direction.

[0041] It is considered particularly advantageous if, in the case of a motor vehicle door mounted in the motor vehicle, the longitudinal direction runs in the longitudinal direction of the vehicle or substantially in the longitudinal direction of the vehicle.

[0042] In connection with an embodiment of the motor vehicle door in which the upper edge of the outer surface at least partially covers the window channel seal in the vertical direction, it is considered advantageous if the sealing element has at least one elastically deformable secondary sealing lip, wherein the sealing element with the at least one secondary sealing lip abuts a sealingly against an inner surface of the upper edge facing the window channel seal. This prevents foreign objects or moisture from entering the area of ​​the mounting rail.

[0043] It is considered particularly advantageous if the sealing element, especially the sealing component or the intermediate component, has at least one further secondary sealing lip, wherein this secondary sealing lip interacts sealingly with an outer surface of the mounting rail facing away from the counter-structure. This prevents foreign bodies or moisture from entering the intermediate area between the retaining structure and the counter-structure, which could adversely affect the sliding motion of the sealing element in the mounting rail.

[0044] It is considered particularly advantageous if the retaining structure and the counter-structure form a dovetail guide or a C-guide. Such a design allows for good displacement of the sealing element and the mounting rail relative to each other along the longitudinal direction of the mounting rail, with good and stable positive locking transverse to the longitudinal direction, and especially perpendicular to the longitudinal direction.

[0045] It is considered particularly advantageous if the mounting rail is connected to the exterior or interior wall via several clip elements distributed along its length. This allows the mounting rail to be installed on the exterior or interior wall particularly easily and quickly.

[0046] It is considered particularly advantageous if the clip elements are an integral part of the mounting rail.

[0047] However, it is also conceivable that the clip elements are separate components.

[0048] The clip elements are preferably spreading clips.

[0049] The sealing element is designed to have a locking mechanism, and the mounting rail to have a corresponding locking mechanism. In an end position, the locking mechanism and its corresponding locking mechanism interlock, securing the sealing element in the mounting rail along its longitudinal direction. This provides tactile feedback when the sealing element is inserted into the mounting rail, confirming that it has reached its predetermined end position. Furthermore, this prevents the sealing element from shifting out of its predetermined end position, as this would require applying significant force to release the locking mechanism and its corresponding locking mechanism.

[0050] The method according to the invention is a method for mounting a window channel seal to a motor vehicle door. The method comprises the following steps: - Providing the motor vehicle door, wherein the motor vehicle door has an outer wall and an inner wall, wherein the outer wall and the inner wall define a window shaft, wherein the window shaft is designed such that a window pane can be moved into and out of the window shaft, - Providing a window shaft seal, wherein the window shaft seal comprises a sealing element and a mounting rail for the sealing element, wherein the sealing element comprises a support component and an elastically deformable sealing component permanently connected to the support component, wherein the sealing element is configured to seal against the window pane with its sealing component when the window shaft seal is mounted on the motor vehicle door, wherein the mounting rail comprises a retaining structure and the support component comprises a counter-structure designed complementary to the retaining structure, wherein the retaining structure and the counter-structure are designed such that the retaining structure and the counter-structure can be brought into engagement with each other by inserting the sealing element into the mounting rail along a longitudinal extension direction of the mounting rail.and when the retaining structure and counter-structure are engaged, the sealing element is held transversely to the longitudinal direction of the mounting rail by a positive-locking interaction of the counter-structure with the retaining structure on the mounting rail, wherein the sealing element (40) has a locking structure (49) and the mounting rail (50) has a locking counter-structure (59), wherein in an end position of the sealing element (40) the locking structure (49) and the locking counter-structure (59) lock together to fix the sealing element (40) in position in the mounting rail (50) with respect to the longitudinal direction of the mounting rail (50), - Permanently connecting the mounting rail to the outer wall or to the inner wall, - Inserting the sealing element, preferably from one end of the mounting rail, into the mounting rail along the longitudinal direction of the mounting rail until the sealing element has reached the final position, wherein the insertion step is carried out after the step of permanently connecting the mounting rail to the outer wall or to the inner wall.

[0051] The advantages and advantageous embodiments described in connection with the motor vehicle door according to the invention apply accordingly to the method for mounting the window shaft seal and vice versa.

[0052] It is quite conceivable that the mounting rail also serves to fix one or more molded part corners in a corner area of ​​the window shaft.

[0053] Another method according to the invention serves to change the position of a window pane in a window recess of a motor vehicle door according to the invention. It is provided that the window pane is mounted in an adjustment mechanism arranged in the window recess, wherein the position of the window pane transverse to the direction of travel of the window pane in the window recess can be changed by actuating the adjustment mechanism, wherein the adjustment mechanism has a tool engagement for actuating the adjustment mechanism, wherein the tool engagement is accessible to a tool from a recess opening of the window recess through which the window pane passes, and wherein the sealing element covers the tool engagement in the end position of the sealing element. The method comprises the following process steps: - Moving the sealing element along the longitudinal direction of the mounting rail out of the end position of the sealing element in such a way that the tool engagement is exposed, - Inserting the tool into the tool engagement via the shaft opening, - Actuating the adjustment mechanism using the tool to change the position of the window pane in the window shaft.

[0054] The above statements regarding the motor vehicle door according to the invention and its advantages and advantageous further developments apply accordingly to the method and vice versa.

[0055] The inventive design of the vehicle door and the inventive method for changing the position of the window pane in the window recess allow for easy and quick readjustment of the window pane's position in the window recess and thus in the vehicle door, since the window recess seal does not need to be completely removed, but only the sealing element needs to be moved within the mounting rail. The tool engagement is preferably positioned in the window recess such that it is not necessary to completely push or pull the sealing element out of the mounting rail, but rather the retaining structure can remain partially engaged with the counter-structure.

[0056] The following figures explain the invention in more detail with reference to exemplary embodiments, without being limited to these. They show: Fig. 1. A motor vehicle in a side view, Fig. 2 a motor vehicle door of the motor vehicle according to Fig. 1 in a first perspective view of an outside of the motor vehicle door, Fig. 3 the motor vehicle door according to Fig. 2 in a second perspective view of the inside of the vehicle door, Fig. 4 A view of the motor vehicle door without the window pane and with the sealing element removed, Fig. 5 the motor vehicle door in a sectional view according to line VV in Fig. 2, Fig. 6 the motor vehicle door according to Fig. 2 in a view from an oblique angle above with the sealing element removed, Fig. 7 a window shaft seal according to a further embodiment in a cutaway view in a perspective view, Fig. 8 the sealing element of the window shaft seal according to Fig. 7 in a cutaway view in a perspective view, Fig. 9 a partial area of ​​a window shaft seal according to an embodiment of the invention in a perspective view, Fig. 10 a first flowchart, Fig. 11 a second flowchart.

[0057] In the figures, a vehicle vertical direction is marked with the reference sign Z, a vehicle longitudinal direction is marked with the reference sign X, and a vehicle transverse direction is marked with the reference sign Y.

[0058] The Fig. Figure 1 shows a motor vehicle 1 in a side view. The motor vehicle 1 has a motor vehicle door 10. The motor vehicle door 10 as such is shown in the Fig. 2 and Fig. Figure 3 shows the vehicle door 10 being a left side door of the vehicle 1. The vehicle door 10 has a vehicle door body made of a metallic material, for example, sheet metal, comprising an outer wall 11 and an inner wall 12. The outer wall 11 and the inner wall 12 define a window opening 17, which is located in the Fig. 5 is indicated. The vehicle door 10 has a movable window pane 20, wherein the window pane 20 can be moved essentially along the vertical direction Z into and out of the window recess 17. The window recess 17 has a recess opening 18, wherein the window pane 20, at least in the raised position, passes through the recess opening 18. The vehicle door 10 is frameless, so that the window pane 20, in the extended position, protrudes freely upwards from the vehicle door 10.

[0059] For the purpose of sealing the window recess 17 against the ingress of foreign objects and / or water, the vehicle door 10 has a multi-part window recess seal 30. The window recess seal 30 has a sealing element 40 and a dimensionally stable mounting rail 50 for the sealing element 40. The mounting rail 50 is permanently connected to the outer wall 11 of the vehicle door 10 by means of clip elements 70, as shown in particular by the Fig. 4 and Fig. 5 can be seen.

[0060] The sealing element 40 can be mechanically coupled to the mounting rail 50 in order to connect the sealing element 40 to the vehicle door 10 via the mounting rail 50. To couple the sealing element 40 to the mounting rail 50, the sealing element 40 has a dimensionally stable support component 41. The coupling of the support component 41 to the mounting rail 50 is effected by a retaining structure 55 formed on the mounting rail 50 and a counter-structure 45, which is complementary to the retaining structure 55 and is part of the support component 41. As particularly evident from the Fig. As can be seen from Figure 5, the retaining structure 55 and the counter-structure 45 are engaged with each other and designed such that the sealing element 40 is displaceable relative to the mounting rail 50 along a longitudinal direction of the mounting rail 50, which runs essentially parallel to the longitudinal direction X, and the sealing element 40 is held transversely to the longitudinal direction, namely both in the vertical direction Z and in the transverse direction Y, by a positive-locking interaction of the counter-structure 45 with the retaining structure 55 on the mounting rail 50. In the case described in the Fig. In the embodiment shown in Figure 5, the retaining structure 55 and the counter-structure 45 are designed in the form of a dovetail guide.

[0061] For sealing purposes, the sealing element 40 has an elastically deformable sealing component 42 that is permanently connected to the support component 41. The sealing element 40 rests against the window pane 20 with its sealing component 42, namely a sealing lip 44 of the sealing component 42, forming a seal. The sealing lip 44 is provided with a flocking 60 in the area of ​​the contact surface with the window pane 20.

[0062] The sealing element 40 has a stop buffer 46 for the sealing lip 44.

[0063] An intermediate component 43 is formed between the support component 41 and the sealing component 42, wherein the sealing component 42 is connected to the support component 41 via the intermediate component 43.

[0064] The carrier component 41, the sealing component 42, and the intermediate component 43 each consist of a plastic, the plastics of the different components 41, 42, and 43 having different Shore hardnesses. The Shore hardness of the plastic of the carrier component 41 is greater than the Shore hardness of the plastic of the intermediate component 43, and the Shore hardness of the plastic of the intermediate component 43 is in turn greater than the Shore hardness of the plastic of the sealing component 42.

[0065] The mounting rail 50 is also made of a plastic, the Shore hardness of the plastic of the mounting rail 50 being greater than the Shore hardness of the plastic of the support component 41.

[0066] The plastic used for the mounting rail 50 is preferably a fiber-reinforced plastic.

[0067] As in particular the Fig. As can be seen from Figure 5, the outer wall 11 has an upper edge 13. The upper edge 13 forms an externally visible edge of the vehicle door 10 adjacent to the window recess 17. The window recess seal 30 is arranged in the window recess 17 below the upper edge 13 in the vertical direction Z. The upper edge 13 is bent towards the window pane 20, so that the upper edge 13 protrudes towards the window pane 20. The upper edge 13 is designed such that it at least partially covers the window recess seal 30 in the vertical direction Z, as can be seen in particular from the Fig. 5 can be seen.

[0068] In order to achieve a good seal in the area of ​​the upper edge 13, the sealing element 40 has an elastically deformable secondary sealing lip 47, wherein the sealing element 40 with the secondary sealing lip 47 abuts a sealing inner surface 14 of the upper edge 13 facing the window shaft seal 30.

[0069] Furthermore, the intermediate component 43 has a further secondary sealing lip 48, wherein the further secondary sealing lip 48 is in a sealing position on an outer side of the mounting rail 50 facing the upper edge 13.

[0070] The window pane 20 is mounted in an adjustment mechanism 80 located in the window shaft 17. By actuating the adjustment mechanism 80, the position of the window pane 20 can be changed transversely to its direction of travel within the window shaft 17. It is conceivable that the position of the window pane 20 can be changed, for example, in the transverse direction Y and / or in the longitudinal direction X via the adjustment mechanism 80. The adjustment mechanism 80 has a tool engagement 81 for actuating the mechanism. The tool engagement 81 is generally accessible to a tool from the upper shaft opening 18 of the window shaft 17. However, when the sealing element 40 is in its end position, the tool engagement 81 is concealed by the sealing element 40, as can be seen in particular from the Fig. 5 can be seen.

[0071] A change in the position of the window pane 20 in the window shaft 17 can be achieved with the one in the Fig. The procedures shown schematically and described below will be carried out in 11 cases.

[0072] A first process step S1' provides for: moving the sealing element 40 along the longitudinal extension direction of the mounting rail 50 out of the end position of the sealing element 40 such that the tool engagement 81 is exposed.

[0073] A second process step S2' provides for: Inserting the tool into the tool engagement 81 via the shaft opening 18.

[0074] A third process step S3' provides for: Actuating the adjustment mechanism 80 using the tool to change the position of the window pane 20 in the window shaft 17.

[0075] The window shaft seal 30 can be mounted on the vehicle door 10 using the method described in the Fig. 10 is shown schematically and described below.

[0076] A first procedural step S1 provides for: Providing the vehicle door 10.

[0077] A second process step S2 provides for: Providing the window shaft seal 30.

[0078] A third process step S3 provides for: permanently connecting the mounting rail 50 to the outer wall 11.

[0079] A fourth process step S4 involves inserting the sealing element 40 from one end of the mounting rail 50 into the mounting rail 50 along its longitudinal direction. This insertion step follows the process step of permanently connecting the mounting rail 50 to the outer wall 11. The insertion of the sealing element 40 into the mounting rail 50 along its longitudinal direction is shown schematically in the Fig. 4 is shown. In this case, the insertion takes place along the longitudinal direction X.

[0080] The Fig. 7 and Fig. Figure 8 shows a further embodiment of the window shaft seal 30. This further embodiment of the window shaft seal 30 differs from the one shown in the Fig. 4 and Fig. The embodiment shown in section 5 differs essentially in the design of the holding structure 55 and the counter-structure 45. Whereas in the embodiment according to the Fig. 5 the holding structure 55 the counter structure 45 on the outside, is in the embodiment according to the Fig. 7 and Fig. 8 provided that the counter-structure 45 surrounds or encompasses the holding structure 55 on the outside.

[0081] The Fig. Figure 9 shows an embodiment according to the invention, wherein this embodiment differs from the embodiment according to the Fig. 7 and Fig. 8 differs essentially in that the sealing element 40 has a locking structure 49 and the mounting rail 50 has a locking counter-structure 59, wherein in the end position of the sealing element 40, which is in the Fig. As shown in Figure 9, the locking structure 49 and the counter-locking structure 59 are interlocked to fix the sealing element 40 in the mounting rail 50 with respect to the longitudinal direction of the mounting rail 50. This prevents, in particular, unintentional displacement of the mounting rail 50 and the sealing element 40 relative to each other in the longitudinal direction of the mounting rail 50 from the end position.
