Description

[0001] Guide device for a flush window of a motor vehicle door

[0002] The invention relates to a guide device for a flush pane of a motor vehicle door, comprising at least one guide rail configured to guide the pane along a predetermined guide direction and at least one sealing device that can be arranged adjacent to the pane in a sealing manner. The invention further relates to a device for flush guiding a pane of a motor vehicle door.

[0003] Flush integration of the windows with the vehicle body can be used to achieve aerodynamic, aesthetic, and functional advantages. This glazing technique can also be referred to as flush glazing. Here, the panes or glass surfaces are integrated into the vehicle body without any protruding edges or frames.

[0004] Since there are no protruding frames, the sealing must be particularly effective to prevent the ingress of water, noise, and dirt. Furthermore, the materials and seals used should be weather-resistant to ensure long-term reliability. Additionally, when integrating glass flush with the frame, it must be ensured that the vehicle's structural integrity and safety are not compromised.

[0005] Against this background, an object of the invention is to improve the flush integration of vehicle door windows with the vehicle body. In particular, the guidance of such a window is to be improved in order to achieve a more visually appealing vehicle design while simultaneously maintaining a sealing function.

[0006] This problem is solved by a guide device for a flush pane of a motor vehicle door with the features of claim 1 and a device for flush guiding a pane of a motor vehicle door with the features of claim 7. The dependent claims relate to advantageous embodiments of the invention.

[0007] According to a first aspect, a guide device for a flush pane of a motor vehicle door is specified, comprising at least one guide rail which is configured to guide the pane along a predetermined guide direction and at least one sealing device which can be arranged adjacent to the pane in a sealing manner, wherein the at least one sealing device is arranged on the guide rail in such a way that a sealing line of the at least one sealing device differs from the guide direction, in particular in a longitudinal direction of the vehicle in the vertical direction.

[0008] Because the sealing line can differ from the guide direction or travel direction of the disc, precise guidance of the disc by means of the guide direction in a longitudinal and / or transverse direction (x- / y-direction) of the vehicle can be enabled, and at the same time the sealing effect of the sealing device can be improved, because the independent arrangement of the guide direction and the sealing line can allow the disc to move freely, especially in the longitudinal direction of the vehicle.

[0009] The guide device is designed to be arranged or attached to the body of the motor vehicle, in particular to at least one vertical pillar. The guide rail defines the guide direction of the disc, allowing the disc to be moved along this direction, primarily in the vertical or z-direction. For this purpose, the guide rail can include a guide receptacle for the disc, or a sliding element for the disc, which defines the guide direction of the disc. This guide direction can also be referred to as the pull-off direction.

[0010] The guide rail or guide receptacle can be designed as a profile, with the guide receptacle being designed as a cylindrical longitudinal recess extending over the entire length of the guide device. The guide direction is defined by the guide rail or guide receptacle in such a way as to avoid or even prevent deviations in movement of the disc, particularly in the x-direction and / or y-direction of the vehicle.

[0011] The sealing line is, in particular, a boundary line or area where the at least one sealing device and the disc meet and ensure a seal to prevent the ingress or escape of liquids, gases, or other substances. The sealing line is thus determined or defined by the design or arrangement of the at least one sealing device on the guide rail and relative to the disc. Because the sealing line and the guide direction or guide receptacle are fixed separately or at a distance from each other on or by means of the guide rail, the disc can be moved along the guide direction or opened and / or closed independently of the sealing device. This can, for example, improve the compression of the sealing device and / or the uniformity of the contact pressure to increase service life.

[0012] According to a further aspect, a device for flush-guided automotive door panes is described, comprising a pane and a guide frame that defines an opening for flush-mounting the pane. The guide frame is formed by a substantially horizontal or substantially horizontally arrangable frame element and two substantially vertical or substantially vertically arrangable frame elements, wherein at least one of the frame elements is or comprises a guide device as described herein. The independent arrangement of the sealing line or the at least one sealing device and the guide direction, which is defined by the guide rail, made possible by the guide device described herein, allows sealing elements or sealing devices to be connected at their free end regions in order to achieve an improved sealing effect.Furthermore, it may be possible to provide a vehicle door that has the visual appearance of a frameless door or a window or pane flush with a vehicle pillar, for example the B-pillar, whereby the manufacture of such a vehicle door may be more cost-effective and / or simpler.

[0013] The invention is based on the idea of ​​separating the vertical joint directions or sealing lines from the removal direction of a window lifter, in order to allow the glass edges to clear relative to the sealing device when the glass is removed, thus reducing stress and wear on the sealing system. For this purpose, a guide device is proposed, comprising, firstly, a guide rail that defines the guidance of the glass along a predetermined guide direction, and, secondly, at least one sealing device that defines a sealing line, wherein the guide direction and the sealing line are distinct. The guide direction and the sealing line can form an angle, and it can be provided that different angles can be defined when multiple sealing devices are used.The guide and sealing line can be straight or curved and have the same or different lengths. By differentiating the guide and sealing elements, the mounting and guidance of the pane along the longitudinal (x-direction) and / or transverse (y-direction) axis of the vehicle can be improved, as the window or pane can be guided independently of the seal. Furthermore, because the guide rail of the guide element defines the direction of movement or guidance of the pane, the guide element or guide rail can be used as a central reference point for joint-forming components, enabling short tolerance chains for the respective joint.

[0014] In one embodiment, the sealing line and the guide direction and / or the sealing device and the guide rail or guide receptacle enclose an angle, whereby it may be provided that different angles can be specified when several sealing devices are provided. Such an angle can lie in a substantially vertical plane, in particular in a longitudinal and / or transverse direction of the vehicle. This allows for a deviation of the sealing line and the guide direction and / or the sealing device and the guide rail or guide receptacle in the longitudinal and / or transverse direction of the vehicle, particularly in the vertical direction.

[0015] In one embodiment, the guide device has a guide receptacle designed to receive a sliding element arranged on the disc. In some embodiments, a sliding element is arranged on the disc and is received by the guide receptacle of at least one guide rail. To guide the disc along the guide direction, a sliding element can be arranged or attached, particularly at the edge of the respective disc and / or facing a vehicle interior. Such a sliding element is received or received by the guide receptacle or the guide rail in such a way that guiding or moving the disc along the guide direction, in particular without deviations from the predetermined guide direction in the x-direction and / or y-direction, is enabled.

[0016] Such a sliding element can, for example, have a sliding head spaced apart from the disc and thickened at its end. This sliding head can be inserted into or arranged in a correspondingly shaped, in particular essentially cylindrical, recess in the guide receptacle or guide rail, enabling it to move along the guide direction, essentially in a vertical direction. The sliding element can, for example, comprise at least one thermoplastic and / or have a spindle-shaped cross-section whose shape is suitable for overcoming any interruption in the sliding movement, which is enabled by the guide receptacle, without noise or wear. In one embodiment, the guide rail and the at least one sealing device are designed to be mechanically fastened to one another.In this configuration, the guide rail and / or the sealing device can each have a complementary fastening element, allowing them to interlock and form a mechanical connection. For example, the guide rail can form a receiving profile in which the sealing device can be at least partially arranged; in other embodiments, the sealing device can be arranged to at least partially surround the guide rail. This allows the guide rail and the at least one sealing device to form an integrated unit, namely the guide device, whereby the guide direction defined by the guide rail can deviate from the sealing line defined by the sealing device.In some embodiments, the at least one sealing device can be arranged on the guide rail by means of an adhesive bond to enable improved attachment relative to each other. This allows for increased degrees of freedom with respect to possible orientations of the at least one sealing device or the sealing line.

[0017] In one embodiment, the guide rail and the at least one sealing device comprise materials from different material groups. One material group can, for example, include metallic materials, another elastomers, and yet another thermosetting materials. In some embodiments, the at least one sealing device can comprise or consist of ethylene propylene diene monomer (EPDM) rubber to increase the wear resistance of the sealing device.

[0018] In one embodiment, the guide device is designed to be attached to at least one vertical pillar of the vehicle. A pillar of the vehicle is, in particular, a vertical or nearly vertical structural element of the body that supports the roof of the vehicle and contributes to the overall stability and / or safety of the vehicle. The pillar furthest forward in the transverse direction of the vehicle is the A-pillar, the so-called B-pillar is located between a front and a rear door, and a C-pillar is typically located behind a rear door of the vehicle. Some vehicle types may also have D-pillars. By arranging the guide device on the vehicle pillar, a cover or panel can be installed in the pillar area to improve the flush fit between the window and the cover.

[0019] In one embodiment, a guide device at least partially geometrically references a window of the vehicle. This allows the arrangement or design of a window above a vehicle pillar, which may abut at least one window of the vehicle, to be predetermined by the guide device, thus enabling a flush seal between the window and the window. Due to the independent arrangement of the guide device from the window assembly, and in particular due to the separation of the sealing line and the guide direction made possible by the guide device, the window can be moved freely, which may increase the service life of the at least one sealing element.

[0020] In one embodiment, the guide frame has a circumferentially closed sealing device. This sealing device can comprise at least one or more sealing elements of one or more guide rails, which can each be connected at their free end regions by means of a formed node to form a circumferentially closed sealing device. Because the at least one sealing element can be positioned freely or independently relative to the guide rail and thus can also have a geometry that deviates from the guide direction in its end region, such a circumferentially closed sealing device is made possible. This can also simplify the assembly of the device. In one embodiment, the at least one guide element or...The guide frame is designed to guide the disc in such a way that, in a closed state, the disc experiences maximum sealing pressure, particularly by means of a circumferentially closed sealing device. Separating the sealing line from the guide direction allows the disc to move freely from this sealed position, which in turn can facilitate the use of trapezoidal discs.

[0021] According to another aspect, a motor vehicle is proposed, comprising at least one guide device and / or a device described herein for flush guiding a window of a motor vehicle door, whereby the effects and / or advantages described herein can be utilized.

[0022] Further advantages and application possibilities of the invention will become apparent from the following description in conjunction with the figures.

Furthermore, the guide device 15 has at least one sealing device 35 adjacent to the disk 12, wherein the sealing device 35 is arranged on the guide device 15 or guide rail 25 such that a sealing line D, particularly in a longitudinal direction of the vehicle, differs from the guide direction R or forms an angle α with it, at least partially.

[0028] The guide device 15 or the guide frame 14 is configured to guide the disc 12 such that the disc 12 experiences maximum sealing pressure in a closed state. For this purpose, the guide frame 14 forms a circumferentially closed sealing device 45 by means of the sealing devices 35 of the guide devices 15, wherein the sealing devices 35 can be sealedly connected to each other in their longitudinal end regions by means of at least one formed node.

[0029] The guide device 15 is attached to a vertical column 16 of the motor vehicle 10 and is configured to at least partially accommodate a cover 17 of the motor vehicle 10 for cladding the guide device 15 and / or the vertical column 16. This allows the guide device 15 to at least partially geometrically reference the cover 17.

[0030] Figure 2 shows a schematic cross-sectional view of the guide device 15 for a flush pane 12 of a motor vehicle door from Figure 1. The guide device 15 is attached to the body or a vehicle pillar 16 by means of a fastening element 116.
