ASSEMBLY OF AN ADJUSTING DEVICE OF A MOTOR VEHICLE

Description

[0001] The invention relates to an assembly of an adjustment device of a motor vehicle, comprising a rail-guided adjustment part, in particular for a functionalized window pane or with a functionalized window pane of a (road-bound) motor vehicle. Such an assembly is known, for example, from DE 20 2015 102 718 U1. It further relates to a window lifter of a motor vehicle comprising such an assembly.

[0002] Such an assembly is understood to mean, in particular, a door module with a carrier plate or such a carrier plate on which components or parts of a window lifter, in particular an electromotive one, preferably a cable window lifter, are arranged or mounted or can be mounted.

[0003] A functionalized window pane is understood here and below to mean, in particular, electrically switchable or controllable (motor vehicle) glazing, i.e., a window pane with an electrically switchable or controllable functional layer, in particular an electrotransparent, an antenna-functional, a heatable, or a luminous layer. In other words, a particularly optical and / or thermal functional layer is provided on the window pane, 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 tintable glazing in the manner of electroactive or electrochromic glass (smart glass).

[0004] To control such functionalized window panes, they must be coupled to an energy source and / or a control device (controller) as electronics to transmit the control signals. Particularly in the case of movable or adjustable window panes of a motor vehicle, such as a side window or a sunroof, the signal transmission connection between the window pane and the electronics is associated with considerable design and assembly complexity.

[0005] In addition, routing lines or a cable with such lines for power and / or signal supply to the window pane often requires complex tools and requires a large amount of installation space. For example, a lever arrangement known from WO 2012 / 069107 A1 as a guide device for a line between connection points on the window pane and on a vehicle element is undesirably complex.

[0006] 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 routing, is also undesirably complex. In addition, unwanted noise emissions occur, for example, when the vehicle door is closed (door slam).

[0007] In a window lifter assembly known from WO 2014 / 122146 A1, a guide device consists of a flexible cable receptacle that guides the cable from a cable feed on a module carrier to the window pane, and a dimensionally stable cable receptacle guide that defines the path of the window pane. The cable receptacle guide is pivotably mounted on the module carrier by means of a pivot bearing and is preloaded in a first direction of rotation by a spring element. When the window pane is lowered, the dimensionally stable cable receptacle guide pivots in a second direction of rotation against the preload of the spring element, while when the window pane is raised, the dimensionally stable cable receptacle guide pivots in the first direction of rotation, assisted by the spring element.

[0008] A structurally simplified cable guide of a window lifter assembly using a dimensionally stable cable receiving guide with 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 area between the module carrier and the vehicle body is known, for example, from DE 20 2015 102 718 U1.

[0009] When using a corrugated tube guided between a guide rail of a window regulator and a guide element, with an (electrical) cable accommodated therein at least in certain areas or sections, there is often the disadvantage or problem that the corrugated tube with the cable accommodated therein for supplying power to the window pane changes shape in a certain position, particularly in an upper or topmost position of the window pane, for example due to temperature. This, in turn, can lead to the corrugated tube with the cable accommodated therein bulging in an undefined manner in other positions of the window pane, and thus being unguided in an undefined area.

[0010] The invention is based on the object of providing a particularly suitable assembly for an adjustment device of a motor vehicle, in particular with a functionalized window pane or for a functionalized window pane. Furthermore, a particularly suitable window lifter is to be provided.

[0011] With regard to the assembly, the problem is solved according to the invention with the features of claim 1, and with regard to the window lifter with the features of claim 10. Advantageous embodiments and further developments are the subject of the dependent claims. The advantages and embodiments cited with regard to the assembly are also transferable to the window lifter, and vice versa.

[0012] The assembly is a component of an adjustment device of a motor vehicle or such an adjustment device itself. The assembly has a support on which at least one guide rail is arranged. The assembly further has an adjustment part that is slidably guided on the guide rail and a flexible guide tube for guiding an electrical cable that is or can be connected to the adjustment part. A first tube end of the guide tube is connected to the support and the second tube end of the guide tube is connected to the adjustment part. During a displacement of the adjustment part along the guide rail, the second tube end moves along in such a way that when the two tube ends approach each other, the guide tube is forcibly displaced in an arc. The guide tube is guided in a guide region that runs in the longitudinal direction of the rail between the guide rail and the support.A spring-loaded or flexible securing element is provided at a securing position along the guide rail and adjacent to and / or spaced from the guide area to secure the guide tube against escaping from the guide area. The assembly can be a seat adjustment or an adjustable sunroof of a motor vehicle.

[0013] In particular, the assembly is a window lift assembly with a carrier plate (module carrier, unit module) as the carrier, for example, of a door module. The assembly has at least one guide rail, on which a driver is guided as an adjustment part. The guide rail, in particular of a single-strand window lift, or two parallel guide rails, in particular of a double-strand window lift, are arranged (mounted) on or at the carrier plate.

[0014] In a cable window lifter, a drive (cable drive), in particular an electric motor drive, is coupled to a cable drum on which at least one traction cable connected to the or each driver is wound as a loop, so that during (window lifter) operation, one end of the cable is unwound from the cable drum and, in particular at the same time, the other end of the cable is unwound.

[0015] In the context of the invention, an adjustment part is generally understood to mean a moving or movable element, in particular a connecting element between vehicle or assembly components. In particular, a driver is understood to mean a connecting element between a window pane and a window lifter of a motor vehicle, which driver adjustably guides the window pane along an adjustment path in order to move the window pane, in the assembled state, along the adjustment path between a closed position and an open position (opening point). The driver thus also has a rail slider or a rail slider function. The window pane is a functionalized, in particular electrically switchable or controllable, window pane. This expediently has an electrical contact point as a connection area. The driver can also comprise a pane adapter connected to the window pane.

[0016] The window lift assembly comprises a flexible, in particular elastic, flexurally elastic, flexurally soft, and / or elastically deformable component as a guide tube for guiding an (electrical) cable or line connected or connectable to the functionalized window pane. A cable is understood here to mean a number of lines, in particular enclosed by a cable or insulating sheath, for conducting current and / or controlling the window pane. The cable or line or lines are suitably coupled to or on the driver as the adjustment part, which is coupled, connected, and / or electrically contacted to the connection area of ​​the window pane.

[0017] The flexible (elastic) component can be designed in the manner of a drag chain or as a hollow tube, whereby a round, for example circular or oval, or an angular, for example rectangular or triangular, profile cross-section of the hollow tube is possible. Preferably, the flexible (elastic) component is a cable receptacle in the form of a corrugated tube, made in particular of plastic. The cable or the or each line is suitably accommodated at least over part of its length, i.e., in sections, inside the component referred to below as the guide tube. The guide tube preferably completely encloses the corresponding cable or line section of the cable used to power and / or control the functionalized window pane—or an electric adjustment drive in the case of an electrically adjustable seat or sunroof.The cross-sectional area of ​​the guide tube or the corrugated tube is preferably round, in particular circular.

[0018] A first tube end of the guide tube, also referred to below as the carrier-side tube end, is held, arranged and / or fastened, preferably stationary, to the carrier plate. The second tube end of the guide tube, also referred to below as the driver-side tube end, is connected to the driver, the adapter or the window pane, and is therefore also held, arranged and / or fastened there. The driver-side (second) tube end is moved along the guide rail during a (vertical) displacement of the driver, typically in the Z direction of the vehicle, such that when the two tube ends approach each other, the guide tube is forcibly displaced in an arc.

[0019] The guide tube is guided in a guide area extending in the longitudinal direction of the rail between the guide rail and the support plate. The guide area is preferably a longitudinal groove or slot, particularly one open in the longitudinal direction of the rail, in which the guide tube rests over part of its circumferential or lateral surface. When the driver is adjusted in the longitudinal direction of the rail along the guide rail, a tube section adjoining the driver-side (second) tube end of the guide tube passes a tube section adjoining the support-side (first) tube end at a distance oriented transversely to the longitudinal direction of the rail.

[0020] At a securing position along the guide rail and adjacent to the guide area, a spring-loaded or flexurally elastic securing element is provided to secure the guide tube against exiting the guide area. The securing position of the securing element is suitably spaced in the longitudinal direction of the guide rail from the first, carrier-side tube end of the guide tube (relative to the typical vehicle coordinates in the Z direction) and is expediently arranged in an area along the guide rail close to the open position of the window pane.

[0021] According to an advantageous development, the securing element has a resilient bending section. The securing element is suitably designed ramp-like with an ascending and a descending sliding ramp. At least one of the sliding ramps is expediently attached to the end of the support or support plate. The securing element is preferably integrally formed on the support or support plate or formed therefrom. In particular, the securing element is designed and arranged such that the driver or the adjusting part, when adjusted in the longitudinal direction of the rail, resiliently deforms the securing element or its resilient bending section at the securing position.In other words, the securing element, which is raised relative to the plane of the carrier plate (of the carrier), and in particular extends from the XY plane in the Y direction relative to the typical vehicle coordinates in the case of the window lifter assembly, deviates into the plate plane of the carrier plate (of the carrier) when it is passed over by the driver (adjustment part) during its adjustment movement.

[0022] In an advantageous embodiment, a holding contour is provided on the support plate or on the support, spaced from the guide rail, in which holding contour a pipe section of the guide tube adjoining the first pipe end is guided. The holding contour is expediently formed from a number of pipe overlaps fastened to the support plate (on the support) or formed therefrom. During a displacement of the driver (adjustment part) along the guide rail into a (second) end position, for example in the open position of the window pane, the guide tube or the pipe section of the guide tube close to the support-side pipe end exits or enters the holding contour when the driver (the adjustment part) is moved along the guide rail into a further (first) end position, for example in the closed position of the window pane.Particularly advantageously, the retaining contour is arranged in an area along the guide rail close to the closed position of the window pane.

[0023] In a particularly suitable application or use, the assembly is provided in a window lifter of a motor vehicle, which window lifter is intended, suitable, and / or configured for a non-functionalized window pane and / or also for a functionalized window pane, for example, a vehicle door. However, the assembly can also be a component, for example, of a sunroof or a seat adjustment mechanism of a motor vehicle.

[0024] An embodiment of the invention is explained in more detail below with reference to a drawing. In the drawings: Fig. 1 shows a detail of an assembly of a (cable) window lifter with a guide tube arranged along a guide rail for an electrical cable for controlling and / or supplying power to a functionalized window pane, which is held or can be fastened (mounted) to a driver guided along the guide rails, Fig. 2 shows a detail in a perspective view of the assembly according to Fig. 1 with opposite the driver position in Fig. 1 in an open position displaced driver-side pipe end, Fig. 3 a perspective sectional view along the line III-III in Fig. 2 , and Fig. 4 and 5 show partial perspective views of the assembly according to Fig. 1 without or with guide tube in the area of ​​a securing element for this purpose.

[0025] Corresponding parts and sizes are always marked with the same reference symbols in all figures.

[0026] Fig. 1shows an assembly 1 as a component of an adjustment device of a motor vehicle, with a carrier plate (carrier) 2, for example of a door module. Specifically, Fig. 1 a window lift assembly, hereinafter also referred to as window lifter, which is used in the Figures 2 to 5 is shown partially (in sections).

[0027] The following provides information regarding the spatial directions, particularly in a motor vehicle coordinate system (vehicle coordinate system), for an exemplary installation situation of a window regulator in a side door of a motor vehicle. The abscissa axis (X-axis, X-direction) is oriented along the vehicle's longitudinal direction (direction of travel), the ordinate axis (Y-axis, Y-direction) along the vehicle's transverse direction, and the applicate axis (Z-axis, Z-direction) along the vehicle height.

[0028] The assembly 1 has at least one guide rail 3, on which a driver 4 as an adjustment part with a rail slider function or a rail slider with a driver function is guided for sliding movement in the longitudinal rail direction L. The guide rail 3 is arranged (mounted) on the carrier plate 2. A holding contour or structure 5 is provided or arranged on the carrier plate 2. The holding contour 5, which is located at a distance from the guide rail 3, is formed in the exemplary embodiment by overlapping elements 5a to 5c formed from the carrier plate 2 and spaced from one another in the Z direction.

[0029] An electric motor drive (cable drive) 6 is coupled, in a manner not shown in detail, to a cable drum on which a traction cable is wound as a loop, which is connected to the driver 4 and guided via deflection elements on the rail or support side, so that when the window lifter is operated, one end of the cable is wound onto the cable drum and the other end is unwound from it. This adjusts a window pane F connected to the driver 4 via a (pane) adapter 4a in order to move it, in the assembled state, along the adjustment path between a closed position (first end position) and an open position (second end position). The window pane F is a functionalized window pane, in particular one that can be electrically switched or controlled. This expediently has an electrical contact point as a connection area, which corresponds to a connection area of ​​the driver 4 or the adapter 4a.

[0030] Furthermore, the assembly 1 has a flexible, i.e. an elastic, in particular flexurally elastic, component in the form of a guide tube 7 for receiving and guiding an electrical cable or line connected or connectable to the functionalized window pane F. The term cable is understood here to mean a number of lines, in particular surrounded by a cable or insulating sheath, for conducting current and / or for controlling the window pane F. The cable is suitably coupled to or on the driver 4 or to the adapter 4a, which in turn is coupled to, connected to and / or electrically contacted with the connection area of ​​the window pane F.

[0031] The flexible (elastic) guide tube 7 preferably functions in the manner of a drag chain and is particularly preferably designed as a corrugated tube. The cable or the or each line is suitably accommodated at least over part of its length, i.e., in sections, inside the flexible guide tube 7. The guide tube 7 is suitably made of a plastic. The guide tube 7 preferably completely encloses the corresponding cable or line section, thus accommodating the corresponding cable section. The cross-sectional area of ​​the guide tube 7 is expediently round, in particular circular.

[0032] The guide tube 7 is held or connected to the support plate 2 with a first, support-side tube end 7a. The other (second) tube end 7b of the guide tube 7 is held or connected to the driver 4 (driver side) or to the adapter 4a or to the window pane F. A first or upper tube section 8a of the guide tube 7 adjoining the support-side tube end 7a is held or connected to the latter or to the support element 2 in the region of the support-side holding contour 5. The holding contour 5 extends in the Z direction and is oriented approximately parallel to the guide rail 3. In particular, the holding structure 5 is arranged at a distance from the guide rail 3.

[0033] At the Fig. 1In the position of the driver 4 shown in a position corresponding to the closed position of the window pane, the first or upper tube section 8a of the guide tube 7 extends from the carrier-side (first) tube end 7a to an approximately U-shaped turning section 8b of the guide tube 7. In this case, the second, driver-side tube end 7b of the guide tube 7 adjoins practically directly to the turning section 8b of the guide tube 7.

[0034] At the Fig. 2In the illustrated driver position, in a position of the driver 4 corresponding to the open position of the window pane, the first, support-side tube end 7a of the guide tube 7 is connected practically directly to its turning section 8b, while a second or lower tube section 8c of the guide tube 7 is connected to the driver-side, second tube end 7b. In other words, the turning section 8b of the guide tube 7 is displaced downwards when the driver 4 is adjusted in the longitudinal direction L of the rail from an upper (first) position (of the window pane F) to a lower (second) position (of the window pane F), or upwards when the driver 4 is adjusted in the opposite direction. The respective lengths of the tube sections 8a and 8c of the guide tube 7 change accordingly.

[0035] In Fig. 1It can be seen that the holding structure 5 is arranged along the guide rail 3 in an area close to the closed position of the window pane. The support-side holding structure 5 is formed from a number of tubular overlaps attached to the support plate 2, preferably formed therefrom, as overlap elements 5a to 5c. The support-side holding structure 5 with its tubular overlaps 5a to 5c is positioned in front of the guide rail 3 at a distance in the X direction.

[0036] During a displacement of the driver 4 in the longitudinal direction L of the rail along the guide rail 3 into an open position of the window pane, the guide tube 7 or its (upper, first) tube section 8a exits the holding contour 5 and re-enters it when the driver 4 moves along the guide rail 3 into one of the positions shown in Fig. 1 corresponding closed position of the window pane F.

[0037] The guide tube 7 is also guided along the guide rail 3. For this purpose, the guide rail 3 has a guide area 9 for the guide tube 7, which extends in the longitudinal direction of the rail. This is a longitudinal groove or a longitudinal channel 10, which acts as a guide channel open in the X direction, in which the guide tube 7 lies over part of its circumferential or lateral surface. The longitudinal groove or longitudinal channel 10 is formed between the support plate 2 and an upstand 11 of the guide rail 3, which protrudes from the support plate's plane.

[0038] The driver-side (second) tube end 7b of the guide tube 7 is moved along the guide rail 3 during a (vertical) displacement of the driver 4 in the Z-direction of the vehicle in such a way that when the two tube ends 7a, 7b approach each other, the guide tube 7 is forced to move in an arcuate manner. The corresponding course of the guide tube 7 from an upper position of the driver 4 corresponding to the closed position of the window pane to a lower position corresponding to the open position of the window pane F is shown in the Figures 1 or 2. The guide tube 7 is initially guided in the holding contour 5 approximately parallel to the guide rail 3 and then increasingly in the guide area 9 running in the longitudinal direction L of the rail between the guide rail 3 and the support plate 2.

[0039] As in Fig. 2As can be seen, the guide tube 7 now lies with the tube section 8c adjoining the driver-side (second) tube end 7b in the guide area 9, i.e. is guided therein. When the driver 4 is adjusted in the longitudinal rail direction L along the guide rail 3, the tube section 8c adjoining the driver-side (second) tube end 7b of the guide tube 7 passes the tube section 8a adjoining the carrier-side (first) tube end 7a at a distance oriented transversely to the longitudinal rail direction L.

[0040] As can be seen from the Figures 3 to 5As can be seen comparatively clearly, a spring-loaded or flexurally elastic securing element 12 is provided at a securing position P along the guide rail 3 and adjacent to the guide region 9 to secure the guide tube 7 against escaping from the guide region 9. The securing element 12 is positioned in front of the guide rail 3 in the X direction at a distance that is preferably at least slightly smaller than the tube diameter of the guide tube 7.

[0041] As in Fig. 5comparatively clearly visible, the distance or the clear width between the securing element 12 and the rail edge of the guide rail 3 facing it is less than or equal to half the diameter of the guide tube 7. The securing position P of the securing element 12 is spaced in the rail longitudinal direction L of the guide rail 3 from the first, carrier-side tube end 7a of the guide tube 7 in the Z direction and is arranged in an area along the guide rail 3 close to the open position of the window pane, as can be seen from Fig. 1 is comparatively clearly visible.

[0042] As from Fig. 5As can be seen, the securing element 12 is a resilient bent section 13 or the securing element 12 has such a bent section 13, which is preferably formed from the carrier plate 2, for example as a stamped and bent part. The securing element 12 is designed in the manner of a gable roof, preferably ramp-like, with sliding ramps 13a and 13b rising and falling in the longitudinal direction L of the rail. One of the sliding ramps - here the sliding ramp 13b - is formed onto the end of the carrier plate 2.

[0043] The securing element 12 is designed and arranged such that the driver 4, when adjusted in the longitudinal direction L of the rail, resiliently deforms the securing element 12 or its resilient bent section 13 at the securing position P. The securing element 12, which protrudes or projects beyond the XY plane of the carrier plate 2, thereby retreats into the XY plate plane of the carrier plate 2 when the driver 4 moves over it during its adjustment movement. The resilient bent section 13 or its sliding ramps 13a, 13b are stretched, i.e. the angle between the sliding ramps 13a and 13b is increased and the bent section 13 is flattened. This reliably prevents the guide tube 7 or a tube section thereof from escaping from the guide area 9.

[0044] In summary, the invention relates to an assembly 1 of an adjustment device of a motor vehicle, comprising a carrier plate as a carrier 2, on which or on which at least one guide rail 3 is arranged, a driver slidably guided thereon as an adjustment part 4, in particular for a functionalized window pane F, and a flexible guide tube 7 for guiding a cable, in particular for supplying power to and / or controlling the functionalized window pane F, wherein the guide tube 7 is guided in a guide region 9 running in the longitudinal direction L of the rail between the guide rail 3 and the carrier plate as a carrier 2, and wherein a spring-loaded or flexurally elastic securing element 12 is provided at a securing position P along the guide rail 3 and adjacent to the guide region 9 to secure the guide tube 7 against escaping from the guide region 9.

[0045] The claimed invention is not limited to the exemplary embodiment described above. Rather, other variants of the invention can also be derived therefrom by a person skilled in the art within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all individual features described in connection 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.

[0046] In addition, the solution described can be used not only in the specific application case described, but also in a similar design in other automotive applications, such as an adjustable sunroof in the vehicle, door and tailgate systems, vehicle locks, adjustable seat and interior systems as well as electric drives, controls, sensors and their application in the vehicle.
