Description

The invention relates to an assembly of an adjusting device of a motor vehicle or for an adjusting device of a motor vehicle, having a rail conductor or (window) driver which is guided on a guide rail and is connected or can be coupled to a functionalized window pane, and having a flexible cable receptacle for an electrical cable for energizing and / or controlling the functionalized window pane.An adjusting device of this type is understood to mean, in particular, a window lifter (window lifter system) or a window lifter assembly having at least one guide rail and having a rail slider or (pane) driver for a window pane, in particular a side door, of a motor vehicle, said rail slider being guided displaceably thereon. Furthermore, the adjusting device or the window lifter assembly, also referred to below as a cable window lifter, is typically assigned an, in particular electromotive, adjusting drive, which is connected or coupled to the rail slider, for example, via a cable system. In the case of a cable window lifter, the adjusting or cable drive is typically coupled to a cable drum on which at least one traction cable connected to the or each rail slider (driver) is wound in the form of a loop.During (window lifter) operation, one cable end of the traction cable is unwound from the cable drum and, in particular simultaneously, the other cable end is unwound, so that the window pane connected to the rail slider (driver) can be moved between a closed position and an open position. The guide rail of the window lifter, in particular of a cable window lifter, can be mounted on a carrier plate of a door module or integrated therein or fastened directly to an inner door part (door blank).A functionalized window pane is understood in particular as an electrically switchable or controllable (motor vehicle) glazing, i.e. a window pane with an electrically switchable or (on) controllable functional layer, in particular an electrotransparent, an antenna functional, a heatable or a lightable layer. In other words, an in particular optical and / or thermal functional layer of the window pane is provided, the functions of which can be influenced, changed, switched or controlled by means of electrical control signals. A functionalized window pane is also understood to mean an ion-curable glazing in the manner of an electroactive or electrochromic glass (smart glass).To actuate such functionalized window panes, they must be coupled to an energy source and / or to a control device (controller) as electronics for the transmission of the control signals. In particular in the case of movable or adjustable window panes of a motor vehicle, for example a side window pane or a sliding roof, the signal transmission connection between the window pane and the electronics is associated with a high level of structural and assembly complexity. In addition, the guidance of electrical lines or of an (electric) cable with such lines for supplying current and / or signals to the window pane is frequently associated with complicated auxiliary means and with a large installation space requirement.A lever arrangement known from WO 2012 / 069107 A1, for example, as a guide device for a line is undesirably expensive between connection points on the window pane and on a vehicle element. A guide device known from DE 10 2009 037 674 A1, which uses a sliding block guided along its own guide rail for cable or line guidance, is also undesirably expensive. A structurally simplified cable guide of a window lifter assembly using a dimensionally stable cable receiving guide having a winding device connected to the module carrier and a guide element which guides a flexible cable receiving means, for example a corrugated tube, during an adjustment of the window pane in a predetermined region between the module carrier and the vehicle body is known, for example, from DE 20 2015 102 718 U1.When using a corrugated pipe guided between a guide rail of a window lifter and a guide element with (electric) cable accommodated therein at least in sections or in sections, there is often the disadvantage or the problem that the corrugated pipe with the cable accommodated therein assumes a change in shape for energizing the window pane in a specific position, in particular in an upper or uppermost position of the window pane, for example due to temperature. This in turn can lead to the corrugated pipe with the cable accommodated therein bulging in an undefined manner in some areas in another position of the window pane and thus being unguided in a non-defined area.In addition, cable guides of this type have only a low flexibility in common with regard to the adaptation to different designs of a body part, in particular a vehicle door, of the motor vehicle, which is why a structurally complicated adaptation of the respective cable guide to the respectively present circumstances is often required.The object of the invention is to specify a particularly suitable assembly of an adjusting device of a motor vehicle, in particular a window lifter assembly, having a cable guide, which can preferably be used flexibly, for a functionalized window pane.This object is achieved according to the invention with the features of claim 1. Advantageous embodiments and developments are the subject matter of the dependent claims (dependent claims).The assembly is part of an adjustment device of a motor vehicle or such an adjustment device itself, in particular a window lifter assembly.The assembly has a flexible guide tube as cable receptacle for guiding a cable, which is connected or can be coupled to a rail slider or to a window pane, in particular a side door of the motor vehicle, for energizing and / or controlling the window pane, and a guide element having a number of holding and / or guide contours for the flexible guide tube. The assembly preferably also has a guide rail for a rail slider or (disk) driver which is held or can be coupled to it in a slidingly movable manner.The window pane is in particular a functionalized, preferably electrically switchable or controllable window pane which, on the one hand, is mechanically connected to the rail slider or can be coupled to the latter and, on the other hand, is electrically connected to or can be coupled to the electrical cable directly or via an adapter. In this case, cable is understood to mean a number of lines, surrounded in particular by means of a cable or insulating sheath, for energizing and / or controlling the window pane. The cable or the respective line is suitably mechanically coupled to the rail slider (driver), in order to be connected to a connection region of the window pane and to be electrically contacted, for example, via an adapter (pane or slider adapter).The guide element is preferably provided or can be provided as a separate component. The guide element or a base body of the guide element is suitably designed in the manner of a cassette, for example with box-shaped depressions or recesses or recesses, or has, for example, a strut- or grid-like structure, in particular for weight reduction. The guide element or its base body suitably has at least one, in particular box-shaped, preferably trapezoidal, depression or recess.According to an expedient embodiment, the guide element has a base body on which the holding and / or guide contours for the flexible guide tube are provided. The holding and / or guide contours are expediently formed on the base body or formed from the base body, in particular in the case of a guide element designed as an injection-molded plastic part, in particular in the case of a guide element produced from a metal sheet as a stamped and bent part.The guide element, in particular in the box-shaped configuration, which is particularly preferably provided as a separate mounting component with or without an already mounted guide tube and is provided and configured for fastening to the guide rail or to a door module or directly to an inner door part or door blank of a vehicle door, is also referred to below as a guide cassette.The guide tube is a flexible, in particular elastic, flexurally elastic, flexurally soft and / or elastically deformable component. The guide tube is suitably a cable receptacle, in particular made of plastic, in the form of a hollow tube, preferably a corrugated tube, which receives the electrical cable or an intended longitudinal cable section. The guide tube, in particular in the form of a corrugated tube, can be completely closed on the circumference or else slit, for example along a longitudinal tube section. The guide tube can also be perforated or, for example, can be formed with slits or the like. These variants are advantageous in order to achieve a suitable discharge of water penetrating into the guide tube.In a suitable embodiment, a first tube end of the guide tube is held stationary or stationary, while the opposite, second tube end of the guide tube is connected or couplable to the rail slider or to the adapter (slider or disk adapter) and is movable relative to the stationary first tube end. The first (stationary) pipe end can be held or fastened on the door inner part (door blank) or on the door module or on its carrier plate. Preferably, the first (stationary) tube end of the guide tube is fastened to the guide element or to its main body and is thus stationary with respect to the movable second tube end.The second tube end of the guide tube is moved along along the guide rail during a displacement of the rail slider or of the window pane coupled thereto in such a way that, when the two tube ends approach one another, the guide tube is forcibly displaced in an arcuate manner. The slider-side (second) tube end is moved along the guide rail during an adjustment of the rail slider in such a way that, when the two tube ends approach, the guide tube is forcibly displaced in an arcuate manner.According to a suitable embodiment, the or each holding and / or guide contour is designed as an, in particular roof-like, tube overlap with an inlet and / or outlet opening for the guide tube. Advantageously, the or each holding and / or guide contour is formed on a bent-up portion of the guide element or on its main body. The bent-up portion thereby advantageously forms a guide groove or channel in which the guide tube is additionally guided.A practical embodiment of the guide element provides that a first group of holding and / or guide contours are arranged on a longitudinal side of the guide element or its base body facing away from the guide rail, in particular in a first longitudinal row. In addition, a second group of holding and / or guide contours can advantageously be arranged on a longitudinal side of the guide element or its main body facing the guide rail, in particular in a second longitudinal row.In the arrangement of the guide element on a rail longitudinal side of the guide rail or along a corresponding rail longitudinal section of the guide rail, the first group of holding and / or guide contours faces away from the guide rail, while the second group of holding and / or guide contours faces the guide rail, i.e. is adjacent to the latter directly or at a provided distance.The respective holding and / or guide contour can advantageously be designed as a tab of approximately L-shaped cross section with an abutment limb connected to the base body of the guide element as a holding contour and with a support or guide limb running transversely to the abutment limb as a holding and / or guide contour for the guide tube. On the side opposite the contact limb, the inlet and / or outlet opening for the guide tube is formed, in particular for a tube section of the guide tube. Via these groove-like or slot-like openings which are open in the rail longitudinal direction, the guide tube which is moved with the rail slide during the movement of the rail slide can slide out of the holding and / or guide contours and slide in again during the movement of the rail slide in the opposite direction.According to a suitable development, the guide element or its base body has a, in particular spring- or flexurally elastic, securing element for securing the guide tube in a guide region spaced apart from the holding and / or guide contour in the rail longitudinal direction.Particularly expediently, the guide element is fastened to the guide rail. For this purpose, the guide element or its base body has a number of fastening contours or fastening lugs. These fastening contours can be suitably designed in such a way that the guide element can also be fastened to an inner door part of a vehicle door or to a carrier, in particular to a module carrier of a door module produced from a (glass fiber-reinforced) plastic. This is advantageous in particular in an embodiment with a guide rail integrated into the door module.A window lifter assembly according to the invention has a carrier, in particular in the form of a door module or a door blank (door inner part), on which at least one guide rail is arranged, on which a rail slider or (pane) driver for a functionalized guide rail is displaceably guided, on which a cable is guided at least in sections via a flexible guide tube, in particular via a flexible guide tube, for energizing and / or for control purposes, said cable being displaceably guided in holding and / or guide contours of a guide element which is fastened or can be fastened to the guide rail or to the carrier, in particular separately provided.The window lifter assembly can also be used without the separately provided guide element in a window lifter which is provided and configured or suitable for a functionalized and / or for a nonfunctionalized window pane of a motor vehicle. This enables the use of identical parts, in particular the guide rail and / or the rail rail, in window lifters for functionalized and non-functionalized vehicle window panes.Exemplary embodiments of the invention are explained in more detail below with reference to a drawing. Shown therein are: FIG. 1 shows a perspective illustration of an assembly of a (cable) window pane with a guide element arranged on a guide rail with a guide tube for an electric cable for energizing a functionalized window pane, which can be mounted on a rail slider guided along the guide rails, FIG. 2 shows a perspective illustration of an embodiment of the guide element with a base body and holding and / or guide lugs for the guide tube which are integrally formed thereon in two parallel longitudinal rows, FIGS. 3 aand 3 b show a perspective illustration of the displacement of the guide tube in the guide element when the rail slider is adjusted along the guide rail from an upper position into a lower position, FIG. 4 shows a detail of a perspective illustration of the guide element arranged parallel to the guide rail with a guide tube connected to the rail slider via an adapter, FIG. 5 is a view according to FIG. 4 showing the guide tube guided past a stationary tube end via the holding and / or guide lugs at a distance oriented transversely to the rail or guide longitudinal direction, FIG. 6 shows a perspective illustration of the assembly comprising the guide rail and the guide element coupled to the window pane in an assembly position on an inner door part (door blank) of a vehicle door, and FIG. 7 shows, in a representation according to FIG. 6, the assembly in an assembly position on a door module.Corresponding parts are provided with the same reference numerals in all figures.Details regarding the spatial directions are also given below, in particular in a coordinate system of the motor vehicle (vehicle coordinate system) regarding an exemplary installation situation of a window lifter in a side door of the motor vehicle. The axis of abscissa (X axis, X direction) is oriented along the vehicle longitudinal direction (driving direction) and the axis of ordinate (Y axis, Y direction) is oriented along the vehicle transverse direction and the axis of application (Z axis, Z direction) is oriented along the vehicle height.FIG. 1 shows an assembly 1 as a component of a window lifter of a motor vehicle, with a guide element 2, also referred to below as a guide device, in the mounting position on a guide rail 3. The rail slider 4 is preferably a plastic injection molded part with two clamping legs, between which the window pane 5 is fixed in a clamping manner by a lower pane region, in particular by means of a snap connection.The assembly 1 has a flexible guide tube 6 as cable receptacle in the form of a corrugated tube. An electric cable 7 is guided in the latter, with which the window pane 5 is energized. In the exemplary embodiment, the electrical cable 7 has a connector plug 8, which can be plug-contacted at a corresponding contact point of the window pane 5. The guide tube 6 is fastened by a first tube end 6 ato the guide element 2 and is thus stationary or stationary with respect to the movable second tube end 6 bcoupled to the rail slider 4. Between the tube ends 6 a, 6 b, an arcuate, in particular circular arc-shaped, turning or curved section 6 cof the guide tube 6 is formed. As a result, the movable second pipe end 6 bcan be guided past the stationary first pipe end 6 ain an adjustment movement of the rail rail rail 4 at a defined distance transversely to the rail longitudinal direction.The guide element or the guide device 2 has a base body 9 and a number of holding and / or guide contours 10, which are preferably designed as lugs (holding and / or guide lugs) 9. In the exemplary embodiment, three guide tabs 10 are provided on the base body 9 and are arranged spaced apart from one another in the longitudinal direction L or in a longitudinal row. The guide lugs 10 extend over the guide tube 6 on the circumference and in the process are roof-like in such a way that the guide tube 6 can slide out of the holding and / or guide contours 10 as a result of an adjustment movement of the coupled rail rail 4 along the guide rail 3 in a transverse direction to the rail longitudinal direction L oriented in the X direction and can slide into the latter without errors in the opposite direction. For this purpose, the guide lugs 10, which are preferably L-shaped in cross section, form longitudinal slot or longitudinal groove-like inlet and / or outlet openings for the guide tube 6, which openings are designated by 11 in FIGS. 2, 4 and 5.In FIG. 2, the guide element or the guide device 2 is shown as a separate component without a guide tube. In this embodiment, the guide element 2 again has a base body 9, on which two parallel longitudinal rows of guide lugs 10 spaced apart from one another in the longitudinal direction L are formed as a holding and guide contour, forming the respective openings 11. In the region of the guide lugs 10 of one of the parallel longitudinal rows, the guide element 2 has a bent-up portion, forming a guide groove or channel 12 for the guide tube 6.The guide element 2, preferably designed as a stamped and bent part, or its base body 9, has a number of recesses 13. For this purpose, in the exemplary embodiment, an approximately drop-shaped and two approximately trapezoidal passage openings are provided as recesses 13. The base body 9 thus has a web-like, grid-like or cassette-like structure.The guide element 2 has a fixing contour 14, on or in which the first tube end 6 aof the guide tube 6 is fixed. The fixing contour 14 is provided in the longitudinal direction L outside the guide lugs 10 forming the guide region for the guide tube 6. In other words, the fixing contour 14 provided on the base body 9 is arranged in a region swept over or crossed through by the guide tube 6 or by its second tube end 6 bin the course of an adjusting movement, in which no guide lugs 10 are provided.On the base body 9 of the guide element 2, a spring-like securing element 15, for example, is provided for securing the guide tube 6. The securing element 15 is arranged in the tab- or contour-free guide region of the guide element 2 spaced apart from the holding and / or guide contour 10 in the longitudinal direction of the rail. The guide element 2 or its base body 9 has a number of fastening contours or fastening lugs 16, for example in order to fasten the guide element 2 to the guide rail 3.FIGS. 3 aand 3 b, as well as 4 and 5, show the assembly 1 with the guide rail 3 and with the guide element 2 arranged thereon in different representations and different adjustment positions of the rail slider 4 and the guide tube 6 moved therewith.As can be seen, in the course of a displacement of the rail rail 4 in the rail longitudinal direction L along the guide rail 3 between an upper closed position in the Z direction and a lower open position of the window pane 5, the second (movable) tube end 6 bof the guide tube 6 on the slider side is guided in such a way that, when the two tube ends 6 aand 6 bare approached, the guide tube 6 is forcibly displaced in an arc shape, forming the turning section 6 c.In the embodiment and arrangement of the guide element 2 according to FIG. 1, the guide tube 6 is accommodated in the guide element 2 in the illustrated position of the rail rail 4 at a lower position, which corresponds to an open position of the window pane 5. In the embodiment and arrangement of the guide element 2 according to FIGS. 3 aand 3 b, the guide tube 6 is accommodated in the guide element 2 when the rail slider 4 is positioned in the position illustrated in FIG. 3 ain an upper position, which corresponds to a closed position of the window pane 5.With a view in particular to FIG. 4, in the embodiment of the guide element 2 with two parallel longitudinal rows of holding and / or guide contours 10, a first group of guide lugs is arranged in a first longitudinal row on the longitudinal side of the guide element 2 facing away from the guide rail 3. A second group of guide lugs 10 is arranged on the longitudinal side of the guide element 2 or its base body 9 facing the guide rail 3 in a second longitudinal row. If only one group of guide lugs 10 is provided, as can be seen in the embodiment according to FIG. 1, this group preferably corresponds to the first group of holding and / or guide contours 10 which are arranged facing away from the guide rail 3.The holding and / or guide contours 10 preferably embodied as approximately L-shaped brackets have an abutment leg 10 awhich is connected to, in particular formed on or formed from, the base body 9 of the guide element 2 and a support and / or guide leg 10 bwhich runs transversely thereto. The contact leg 10a forms a holding contour for the guide tube 6 in order to avoid deflection in the X direction out of a guide track defined by the holding and / or guide contours 10. The support leg 10 bis effective as a guide contour against the guide tube 6 moving out of the guide track defined by the holding and / or guide contours 10 in the Y direction. On the side opposite the contact limb 10 a, the respective inlet and / or outlet opening 11 for the guide tube 6 or for a corresponding tube section is formed, so that the latter can pass or be displaced from the holding and / or guide contours 10 into the region outside the holding and / or guide contours 10.FIGS. 6 and 7 show the assembly 1 in an assembled state for or on a carrier 18 of a vehicle door (side door). In the embodiment according to FIG. 6, the carrier 18 is an inner door part (door blank). The guide rail 3 and the guide element 2, in particular with the guide tube 6 already mounted and the electrical cable 7 already accommodated therein in a suitable manner, can be fastened to said guide rail jointly or separately, for example by screw fastening.In the embodiment according to FIG. 7, the carrier 18 is a carrier plate of a door module, to which the guide rail 3 and the guide element 2 can again be fastened, for example screw-fastened, together or separately with the guide tube 6 already mounted.
