Abstract
Description
Technical Field
[0001] The invention relates to an adjusting device for a functionalized window pane of a motor vehicle, in particular for a movable or movable side window pane. Background Art
[0002] Such an adjusting device is understood in particular to be a component or a member of a window lifter, in particular an electric motor-type window lifter, preferably a cable-type window lifter, for a functionalized window pane, for example a side window pane in a vehicle door.
[0003] Functionalized glazings are understood to be, in particular, electrically switchable or electrically controllable (motor vehicle) glazings, i.e. glazings with electrically switchable or electrically (actuated) controllable functional layers, in particular glazings with electrically transparent layers, layers with antenna functions, heatable layers or luminous layers. In other words, glazings are provided with, in particular optical and / or thermal functional layers, the function of which can be influenced, varied, switched or controlled by means of electrical control signals. Functionalized glazings are also understood to be tintable glazings in the form of electroactive or electrochromic glazings (smart glazings).
[0004] In order to control such a functionalized window pane, it is necessary to couple the functionalized window pane to an energy source and / or a control device (controller) as an electronic device for transmitting control signals. In particular, in the case of movable or adjustable window panes of motor vehicles, such as side windows, the connection between the window pane and the electronic device in terms of signal transmission technology involves a high level of construction and assembly technology expenditure.
[0005] Furthermore, the routing of the lines for supplying current and / or signals to the functionalized window pane or the cables with such lines is typically accomplished by directly connecting the cables and / or the plug contacts connected to the cables to the window pane-coupled drivers or rail sliders of the single-strand or double-strand window lifter, for example using a rod arrangement. As a result, the routing of the cables or lines is dependent on the positioning of the components of the window lifter and the respective embodiment or design, which is often undesirable with regard to the resulting limited flexibility and the need for coordination with the components of the window lifter. Summary of the invention
[0006] The object of the present invention is to specify a particularly suitable adjusting device for a functionalized window pane of a motor vehicle. In particular, the guidance of lines or cables having such lines for supplying current and / or signals to the functionalized window pane should be as independent of the window lifter or its components as possible, for example in terms of suitable positioning. Furthermore, a particularly suitable and as independent of the window lifter or its components as possible guiding system for guiding such lines or cables to a functionalized window pane, in particular a side window, of a motor vehicle should be specified.
[0007] According to the invention, this object is achieved with respect to the adjustment device by means of the features of claim 1 and with respect to the guide system by means of the features of claim 10. Advantageous embodiments and improvements are the subject matter of the dependent claims. The advantages and embodiments listed with respect to the component can also be transferred to the guide system and vice versa.
[0008] The adjusting device has a window lifter for adjusting a functionalized window pane along an adjustment path and has a guide system for a cable connected or connectable to the functionalized window pane for conducting current and / or controlling the functionalized window pane. The guide system has a flexible component for accommodating the cable and a sliding element coupled to the window pane, which is guided along the adjustment path on a rail-shaped guide element separate from the window lifter. The flexible component is preferably held on the one hand on the sliding element of the guide system and on the other hand in a positionally fixed manner on a body part of the motor vehicle, in particular on a door module or a door frame.
[0009] The window lifter has in a suitable manner at least one guide rail with a drive for the window glass guided thereon in a movable manner, and an adjusting drive, in particular an electric motor, which is connected (coupled) to the drive via a traction cable. The window lifter can be designed as a single-stranded guide rail or as a double-stranded guide rail with two parallel guide rails. The rail-shaped guide element of the guide system for the sliding element is arranged parallel to one or each guide rail and is arranged separately from the window lifter. The rail-shaped guide element of the guide system is therefore an element (component) additional to one or each guide rail of the window lifter, preferably in the form of a guide rail that is also provided or set up as a sliding element.
[0010] The sliding element of the guide system is preferably coupled to the window lifter only via the window glass. In other words, the components of the window lifter, in particular one or each drive element and the traction cable coupled to the drive element and to the cable drive, are at most indirectly coupled to the guide system via the window glass and in this case in particular to the separately guided sliding element. Thus, without the window glass, there is no connection between the guide system and the window lifter or to the components of the window lifter. This provides more freedom and possibilities for positioning the guide system, in particular in the door body or door frame. As a result, the components of the window lifter and the components of the guide system can be determined and / or designed independently of one another.
[0011] In a suitable design, the flexible component acts in the form of a drag chain and is implemented, for example, as a flexible tube (hollow tube). It is particularly advantageous to implement and / or act as a bellows, especially a flexible component made of plastic material. The flexible component preferably wraps the cable at least almost completely. Suitably, the flexible component is guided on and / or under the rail-shaped guide element of the guide system. For this purpose, the rail-shaped guide element of the guide system advantageously has a guide area for the component extending in the longitudinal direction of the track. For this purpose, the rail-shaped guide element is designed in a suitable manner with a (longitudinal) groove or channel extending in its longitudinal direction.
[0012] According to a particularly advantageous development, the sliding element of the guide system is coupled or can be coupled to the functionalized window pane or to a glass adapter connected to the functionalized window pane via a flexible connecting element. In a suitable manner, the flexible connecting element is connected in an articulated manner to the window pane or the glass adapter and / or the sliding element. For this purpose, for example, a hinge-like connection can be established between the sliding element guided in a movable manner on a rail-like guide element and a glass adapter provided in addition as a glass adapter assigned to the window pane.
[0013] A guide system for a cable connected or connectable to a functionalized window pane for current conduction and / or control of the functionalized window pane comprises a flexible component for accommodating the cable and a sliding element coupled to the functionalized window pane, preferably via a flexible connecting element, the sliding element being guided on a rail-shaped guide element and connected to the flexible component. The guide system can be mounted independently of the window lifter or a component of the window lifter and can in particular be freely positioned on a frame (door frame, door frame) of a vehicle door.
[0014] The coupling to the guide system is only established when the functionalized window pane or side pane of the vehicle is installed and coupled to the window lifter. Only after the coupling via the functionalized window pane or side pane does the sliding element of the guide system move synchronously with one or each driver of the window lifter. In this case, the cable guided in the flexible component is guided from the door frame or from the electronics arranged on the door frame to the window pane or side pane without collision or damage over the adjustment path or adjustment stroke.

[0019] Parts and dimensions that correspond to one another are provided with the same reference symbols in all the figures. DETAILED DESCRIPTION
[0020] The description of the spatial directions below is also explained in particular in the coordinate system of the motor vehicle (vehicle coordinate system) with reference to an exemplary installation position of a window lifter in a side door of the motor vehicle. The transverse axis (X axis, X direction) is oriented in the longitudinal direction of the vehicle (driving direction), the longitudinal axis (Y axis, Y direction) is oriented in the transverse direction of the vehicle, and the vertical axis (Z axis, Z direction) is oriented in the height direction of the vehicle.
[0021] Figure 1 and Figure 2 An adjusting device or a component 1 as a component of an adjusting device in a side door of a motor vehicle is shown. Figure 1The door frame or door frame 2 is shown without a door skin (outer sheet) and without a door interior panel. In this embodiment, a double-stranded (hereinafter referred to as a window lifter FH) window lifter assembly for a functionalized window glass (side glass) 3 and a guide system FS for a flexible component 4 are installed in or on the door frame or door frame 2, in which a cable 5 leading to the window glass 3 is accommodated. Figure 3 and Figure 4 The guide system and the window lifter are shown partially or in section.
[0022] The window lifter of the adjusting device 1, which is designated by FH, has a first guide rail 6 and a second guide rail 6 parallel thereto, on which a driver 7 having the function of a rail slider is guided in a movable manner in the longitudinal direction L of the rails along an adjustment path W oriented essentially in the Z direction ( Figure 2 ). The driver 7 with the function of a rail slider can also be called a rail slider with the function of a driver for the window glass 3. The coupling of the driver 7 to the window glass 3 is realized here respectively via a glass adapter 8. The respective guide rails 3 are mounted on the door frame (door skeleton) 2.
[0023] The window lifter FH of the regulating device 1 also has an electric motor drive (regulating drive or cable drive) 9. The drive has an electric motor (not specifically designated), which is coupled to a transmission, in particular a worm gear, and to a cable drum in a manner not specifically shown. Figure 4 ) is wound around the cable drum as a loop, so that when the window lifter is in operation, one cable end is unwound from the cable drum and the other cable end is wound onto the cable drum. In this way, the window glass 3 connected to the driver 7 is adjusted so that the window glass moves along the adjustment path W between the closed position and the open position in the assembled state.
[0024] Figure 1 and Figure 2 , the driver 7 for the functionalized window pane 3 is shown in the upper and lower positions and in the intermediate positions on the respective guide rail 6 along the adjustment path W. The window lifter FH, which is designed as a so-called cable window lifter and is double-stranded in the present embodiment, has as essential components the guide rail 6 and the driver 7 guided thereon in a movable manner, as well as an adjustment drive 9 and a traction cable 11. In the present example, the traction cable is designed as a Bowden traction element.
[0025] The functionalized window pane 3 is electrically switchable or controllable. For this purpose, the functionalized window pane has an electrical contact point as a connection area 13 directly or via a glass adapter 12. A plug contact (contact plug, contact element) 14 makes electrical contact at the connection area. The plug contact 14 is connected to the cable 5. The flexible (elastic) component 4 acts in the manner of a drag chain and is preferably embodied as a bellows.
[0026] The cable 5 is accommodated in the interior of the flexible component 4 at least over part of its length, that is to say in sections. Here, the cable refers to several lines for current conduction and / or control of the functionalized window pane 3, which are surrounded, in particular, by means of a cable sheath or an insulating sheath. The flexible component 4 can be made of plastic. The flexible, that is to say elastic, in particular flexurally elastic component 4 can preferably completely wrap the corresponding cable section or line section. The cross section of the component 4 is preferably round, for example a perfect circle, but can also be polygonal, for example a rectangle.
[0027] The corrugated tube 4 is a flexible component in which the cable 5 is guided and by which the cable 5 is protected, and is held on the door frame 2 at its tube end 15 away from the plug contact 14. There, the cable 5 is connected, contacted and / or coupled to the energy source and / or the control device (controller, electronic device) in a manner and method not shown in detail. Preferably, a retaining clamp 16 is additionally provided on the frame side or frame side for section-wise or regional-wise clamping of the corrugated tube 4 and the cable 5 guided therein ( Figure 2 ).
[0028] Especially in combination Figure 3 and Figure 4 It can be seen more clearly that the guide system FS has a guide rail arranged separately from the window lifter FH as a guide element 17 and a sliding element 18 guided on the guide element in a movable manner. A flexible component designed as a bellows 4, which again accommodates or guides the cable 5 in a protective manner, is held on the sliding element at the end. The sliding element 18 is coupled to the functionalized window pane 3 in the area of the glass adapter 12 or the contact point 13 there. Therefore, when the window lifter FH is in operation, the sliding element 18 is guided along the adjustment path W on the rail-shaped guide element 17 separated from the window lifter FH.
[0029] The coupling of the sliding element 18 is realized only via the functionalized window pane 3, and the flexible component 4 is held on the sliding element 18 of the guide system FS on the one hand, and on the other hand, is held in a fixed position on the door module or door frame 2. Here, the rail-shaped guide element 17 of the guide system FS for the sliding element 18 is arranged parallel to the guide rail 6 of the window lifter FH and is held on the door frame 2. The guide system FS has the rail-shaped guide element 17 as the main component and the sliding element 18 guided on the guide element in a movable manner, and the flexible component 4 for the cable 5 connected to the sliding element and implemented as a bellows.
[0030] The rail-shaped guide element 17 of the guide system FS has a guide region 19 in the form of a longitudinal groove or channel extending in the longitudinal direction L of the rail ( Figure 4 ). When the sliding element 18 moves from Figures 1 to 4 The upper positioning shown in the figure travels to Figure 1 and Figure 2 In the middle or lower position shown in FIG. 1 , the bellows 4 is guided in this longitudinal groove or channel.
[0031] As from Figure 3 and Figure 4 It can be seen relatively clearly that the sliding element 18 of the guide system FS is coupled to the functionalized window pane 3 or to the glass adapter 12 connected to the functionalized window pane via a flexible connecting element 20. The flexible connecting element 20 is designed in the form of a strip or a strip. The connecting element 20 is connected in an articulated manner to the functionalized window pane 3 or the glass adapter 12. For this purpose, an articulated connection is established between the sliding element 18 guided on the rail-shaped guide element in a movable manner and the glass adapter 12.
[0032] In the present embodiment, the hinged connection between the strip-shaped or band-shaped connecting element 20 and the glass adapter 12 is implemented as a hinge pin 21 on the connecting element 20 and a corresponding hinge ring in the form of a hinge band 22 on the glass adapter 12. The articulation axis or rotation axis of the hinge-shaped connecting elements 21, 22 is oriented in the X direction. In addition, the strip-shaped or band-shaped connecting element 20 is bendable or twistable, so that, for example, tolerances are compensated and, in particular, the necessary or sufficiently flexible connection of the sliding element 18 to the functionalized window glass / side glass 3 is provided independently of the window lifter FH or its components. Therefore, the sliding element 18 of the guide system FS only runs synchronously with one or each driver 7 of the window lifter FH after coupling via the window glass or side glass 3. In this case, the cable 5 guided in the flexible component 4 is guided from the door frame 2 to the window glass or side glass 3 on the adjustment path (adjustment stroke) W without collision and damage.
[0033] When one or each entrainment member 7 is adjusted along the guide rail 6 of the window lifter FH in the longitudinal rail direction L, the component section of the bellows 4 that is movable in the rail-shaped guide element 17 is adjusted relative to the component section of the bellows 4 that is fixed to the frame or to the frame. In this case, when the entrainment member 7 is adjusted along the guide rail 6 of the window lifter FH, the movable component section passes the component section of the bellows 4 that is fixed to the carrier at a distance oriented transversely to the longitudinal rail direction L (i.e. oriented in the X direction) both in the direction of the closed position of the functionalized window pane 3 and in the direction of the open position. In other words, with reference to a typical (common) vehicle coordinate system, the movable component section running in the Z direction passes the component section of the bellows 4 that is fixed to the carrier at a distance oriented in the X direction from the guide element 17 of the guide system FS, which is itself spaced apart from the window lifter FH and in particular from the guide rail 6 of the window lifter.
[0034] The flexible or elastic component in the form of a bellows 4 is preferably guided both in the X direction and in the Y direction by means of a supporting or retaining contour 16. The flexible component 4 and the cable 5 guided therein are stable in the XZ plane of the door frame 2 and preferably cannot deviate in the Y direction.
[0035] In summary, the invention relates to an adjusting device 1 for a motor vehicle, which has a window lifter FH for adjusting a functionalized window glass 3 and a guide system FS for a cable 5 for conducting current and / or controlling the functionalized window glass 3, wherein the guide system FS has a flexible component 4 for accommodating the cable 5 and has a sliding element 18 coupled to the window glass 3, which is guided on a rail-shaped guide element 17 that is separate from the window lifter FH.
[0036] The claimed invention is not restricted to the exemplary embodiments described above. On the contrary, a person skilled in the art can also derive further variants of the invention within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all individual features described in conjunction with the various exemplary embodiments can also be combined in other ways within the scope of the disclosed claims without departing from the subject matter of the claimed invention.
