Description

The present invention relates to a guide element for a motor vehicle side window, a motor vehicle side window with the guide element, a side door for a motor vehicle with the motor vehicle side window and a motor vehicle with the side door.

the EP 3 647 093 A1 relates to glazing intended to be installed in a door frame of a motor vehicle, the glazing comprising at least one movable pane carrying at least one guide shoe on its side facing the passenger compartment. The guide shoe is mounted in a guide rail on the vehicle door and can be displaced relative thereto, so that the glass pane can be moved between a closed position and at least one open position. In this case, the at least one guide shoe is removably mounted on a guide shoe carrier which is fixedly attached to the movable glass pane.

Also known is a guide element which is designed as a two-component component (2K component) and is bonded to a motor vehicle side window.

The conventional guide element designed as a 2K component has a carrier with a carrier material as the first component and a sliding element with a sliding material as the second component, which has a lower coefficient of friction than the first component and therefore better sliding properties.

The different coefficients of expansion of the two materials of the guide element pose a particular challenge and therefore require a corresponding structural design.

Depending on the geometry of a guide rail on the vehicle door, the sliding element can be divided into individual sliding segments. The sliding element, which is designed in the form of such comparatively short sliding segments, has the advantage that the sliding element experiences fewer temperature-related deformations compared to a sliding element designed continuously or in one piece, especially under extreme temperature fluctuations.

A disadvantage of a sliding element composed of a plurality of individual segments, however, is, among other things, increased assembly and production costs compared to a sliding element designed in one piece.

Against the background of this prior art, the object of the present invention is to specify a device which is suitable for overcoming at least the above-mentioned disadvantages of the prior art.

In particular, a guide element designed as a 2K component is to be provided, which has a sliding element designed in one piece.

The problem is solved by the features of the independent claim. The dependent claims relate to preferred developments of the invention.

According to this, the object is achieved by a guide element for a motor vehicle side window, which has a carrier element and a sliding element.

The carrier element is provided for fixing the guide element to the motor vehicle side window and has or consists of a first material.

The sliding element is connected to the carrier element and can be connected to a guide rail on the vehicle door. The sliding element is designed in one piece and has or consists of a second material which has a lower coefficient of friction compared to the first material.

In the present case, the coefficient of friction can relate to the suitability of a material to slide with as little sliding friction as possible on another material, in particular rubber of a seal.

The sliding element has a T-profile, which is arranged in a longitudinal recess of the carrier element designed as a through hole for the positive connection of the sliding element to the carrier element, with a length of the recess of the carrier element being greater than a length of the T-profile of the sliding element.

Because the carrier element and the sliding element have or consist of different materials, a guide element designed as a 2K component is provided. These two materials are connected to one another by the positive connection of the carrier and sliding element via the T-profile of the sliding element arranged in the recess of the carrier element.

In order to take into account the possibly different expansion coefficients of the two materials of the guide element, the Aus recess of the carrier element has a greater length than a length of the T-profile of the sliding element.

As a result, a relative movement between the sliding element and the carrier element is possible and unwanted deformation of the components can be avoided despite the one-piece or integral design of the sliding element.

Contamination and damage to a seal on the vehicle door, within which the sliding element can be arranged, can thus be prevented or minimized and assembly of the guide element can be simplified. This can contribute to an optimized and compact design and appearance of the motor vehicle.

The carrier element can have a groove arranged, in particular circumferentially, along the recess. If the carrier element is attached to the motor vehicle side window by gluing, this groove can serve as a so-called overflow groove for an adhesive mass displaced during bonding, so that it does not reach a region of the motor vehicle side window that is visible to an observer.

The sliding element can be L-shaped and/or U-shaped in an end area of the support element and can encompass the support element in the end area, with the end area being attached to an upper and/or lower edge of the motor vehicle side window is adjacent.

“Up” and “down” in the present case refer to a vehicle height direction running essentially parallel to the vertical.

In other words, the sliding element can be L-shaped and/or U-shaped in cross section in a region which is arranged in a mounted state of the guide element in the vehicle door-side guide. The L-shaped or U-shaped area then forms a so-called casing for an upper or a lower end area of the carrier element.

Furthermore, a motor vehicle side window or side window glazing for a motor vehicle is provided with a guide element as described above, which is arranged in a lateral edge area of the motor vehicle side window.

What has been described above with reference to the guide element also applies analogously to the motor vehicle side window and vice versa. “Lateral edge area” in the present case refers to an outer area of the motor vehicle side window that is at the front and/or rear in the longitudinal direction of the motor vehicle.

The carrier element can be glued or adhered to the side edge region of the motor vehicle side window in order to fix or attach it to the motor vehicle side window.

The recess of the carrier element, in which the T-profile of the sliding element is arranged, can be arranged in the lateral edge area of the motor vehicle side window and the sliding element can be moved over the lateral edge area of the motor vehicle side window in the direction of the guide rail on the vehicle door, i.e. in the longitudinal direction of the vehicle forwards and/or backwards , protrude beyond the motor vehicle side window.

The motor vehicle side window can be designed as flash glazing. Flash glazing can be understood to mean a pane of glass whose color is created by lamination during manufacture. This allows glazing to be provided which allows light to pass through but is opaque to some extent.

Furthermore, a side door for a motor vehicle is provided, the side door having the motor vehicle side window described above and a guide rail in which the sliding element of the guide element is movably mounted. What has been described above with reference to the guide element and the motor vehicle side window also applies analogously to the side door and vice versa. The guide rail can run essentially parallel to the vehicle height direction and guide the motor vehicle side window in a vehicle width direction, which is perpendicular both to the vehicle longitudinal direction and to the vehicle height direction.

The guide rail can have a seal which is arranged and designed in such a way that it seals the vehicle interior against liquids penetrating from the outside.

Furthermore, a motor vehicle is provided with the side door described above. What has been described above with reference to the guide element, the motor vehicle side window and the side door also applies analogously to the motor vehicle and vice versa. The motor vehicle can be a passenger car.

The following is an embodiment related to 1 and 2 described.

• 1 shows a perspective view of an upper part of a guide element for a motor vehicle side window, and
• 2 Figure 12 shows a perspective view of the upper part of the guide element 1 , which is mounted on the motor vehicle side window.

In 1 a guide element 1 for a motor vehicle side window 2 designed as flash glazing is shown on its own and in 2 is the motor vehicle side window 2 with the in 1 illustrated guide element 1, which is mounted or attached to the motor vehicle side window 2, shown.

The guide element 1 has a carrier element 3 for fixing the guide element 1 to the motor vehicle side window 2 and a one-piece sliding element 4 connected to the carrier element 3 .

The carrier element 3 is fastened to the motor vehicle side window 2 in a lateral edge area of the motor vehicle side window 2 by means of an adhesive connection. That is to say, the sliding element 4 is fastened to the motor vehicle side window 2 via the carrier element 3 .

The connection of the sliding element 4 to the carrier element 3 is a positive connection. For this purpose, the sliding element 4 has a number of T-profiles 5 and the carrier element 3 has a number of elongated recesses 6 designed as through-holes.

In 1 a recess 6 with a T-profile 5 is shown as an example, which will be described in detail below, with this following description also applying analogously to the other recesses and T-profiles that are not shown.

Within the recess 6 of the carrier element 3, the T-profile 5 of the sliding element 4 is arranged.

The recess 6 of the carrier element 3, in which the T-profile 5 of the sliding element 4 is arranged, is arranged in the lateral edge region of the motor vehicle side window 2. The sliding element 4 protrudes beyond the lateral edge region of the motor vehicle side window 2 in the direction of a guide rail (not shown) on the vehicle door side beyond the motor vehicle side window 2 .

In a state (not shown) in which the motor vehicle side window 2 with the guide element 1 attached to it is fastened to a motor vehicle door, in particular a motor vehicle side door, the sliding element 4 is arranged within the guide rail of a frame of the motor vehicle door.

When opening and closing a motor vehicle side window defined by the frame, the motor vehicle side window 2 moves relative to the vehicle door-side guide rail, the sliding element 4 being in contact with a seal arranged in the guide rail and sliding along and relative to the guide rail.

The seal seals the vehicle interior from an external vehicle environment, so that no moisture and/or no dirt can penetrate into the vehicle interior from the outside.

In order to produce as little wear as possible due to the sliding movement, the carrier element 3 has a different material than the sliding element 4 .

More precisely, the carrier element 3 comprises or consists of a first material and the sliding element 4 comprises or consists of a second material, the second material having a lower coefficient of friction compared to the first material.

Due to the different materials of carrier element 3 and sliding element 4, these two elements 3, 4 each have a different coefficient of expansion.

The expansion coefficient or thermal expansion coefficient is a parameter that describes the behavior of a material with regard to changes in its dimensions with temperature changes.

In order to avoid deformation of the carrier element 3 and/or the sliding element 4 due to the different expansion coefficients when the temperature changes during operation of the motor vehicle, a length L1 of the recess 6 of the carrier element 3 is greater than a length L2 of the T-profile 5 of the sliding element 4, so that the sliding element 4 can move relative to the carrier element 3.

In the present case, the carrier element 3 also has a groove 7 arranged along the recess 6 . In the present case, the groove 7 is configured so that it encloses the plurality of recesses 6 of the carrier element 3 .

When the carrier element 3 is bonded to the motor vehicle side window 2, part of an adhesive compound required for bonding is pushed outwards by the pressure generated. This displaced part of the adhesive can be accommodated in the groove 7 and thus can be prevented that the adhesive in one for one Observer of the motor vehicle visible area of the motor vehicle side window 2 passes.

The sliding element 4 also has in the 1 and 2 shown end area of the guide element 1, ie the area of the support element 3 which adjoins an upper or lower edge 8 of the motor vehicle side window 2, has a U-shaped cross section and encompasses the support element 3 in this end area. An L-shaped cross section would also be conceivable.
