Description

Window regulator assembly with a single elastic LeitungsfUhrungseiement

description

The present invention relates to a window regulator assembly for a vehicle according to the preamble of claim 1.

Such a window regulator assembly has inter alia a window pane that is adjustable relative to a stationary vehicle element along a predetermined adjustment path. Furthermore, at least one line is provided, which is coupled to the adjustable window pane and extends to the vehicle element, so that the course of the line must change during an adjustment of the window pane. The line can be provided here for the connection of the window to a power source and / or a circuit and / or control electronics. For example, the window pane can have a switchable glazing for changing the optical properties of the window pane and / or a heating element. In the former case, it may be provided, for example, to be able to change the transmittance of the window pane, so that the window pane can be darkened and / or switched transparent at the push of a button so that, in particular, switching signals are to be transmitted to the window pane via the line. In the latter case, the line is used to power the heating element provided within the window pane.

Since such a line with both the adjustable window pane and with the stationary vehicle element, such. B. a door component, door module carrier or Door panel is connected and can not be laid loose to avoid rattling noises, z. For example, from DE 10 2009 037 647 A1 discloses a cable guide element for a motor vehicle door, via which a line between a first connection point on the window or a window pane connected to the component and a second connection point is guided on a stationary vehicle element to this over the course to specify the line during an adjustment of the window. In this way it is avoided that the line damaged, for example, within a motor vehicle door by the adjustment of the window and during acceleration - for example, by slamming the vehicle door or while driving the motor vehicle - unwanted noise due to the striking of the line to a component of the window regulator assembly are generated.

In DE 10 2009 037 674 A1 a longitudinally extended and flexible cable guide element is proposed, on which the line is guided at least in sections along. In one embodiment, the single, flexible cable guide element is formed by a flat spring steel strip on which the line is fixed or which is surrounded by a plastic jacket, in which the line is embedded. The cable guide element is here preferably slidably guided over an additional guide means in the form of a sliding block along its own guideway to selectively influence the course of the Leitungsführungseiements at an adjustment of the window and each pretending a certain relative position and orientation of the Leitungsführungseiements relative to the window pane and the vehicle element , By providing a slidably guided sliding block for the cable guide element, a bending radius which remains as constant as possible during the adjustment should be achieved between the sections of the cable guide element which is deflected or bent at least once. In addition, the sliding block secures the cable guide element at an additional location within the vehicle door, preferably on the vehicle element, since even with a flat and laid under tension between the two connection points spring steel strip as a cable guide element can not be completely ruled out that the cable guide element, for example, at a door supplement noisy strikes inside the vehicle door. However, the provision of an additional slidably guided sliding block on a cable guide element increases the costs and the assembly costs for a window regulator module equipped therewith. It is therefore an object of the present invention to further improve a generic window regulator assembly and to further reduce the assembly effort in an equipment of the window regulator assembly with a cable guide element.

This object is achieved with the window regulator assembly of claim 1.

The window regulator assembly according to the invention provides a single, elongated cable guide element which

is curved transversely to its longitudinal extent, so that the cable guide element has a curvature in cross-section, and

- Is also designed so elastic that the deflected between the window and the fixed vehicle element line guide element is endeavored because of its elasticity, not only to run straight, but also to maintain its curvature.

Consequently, in an unassembled state, a cable guide element according to the invention would run along a straight line without external loads and would have a continuous curvature transverse to this straight line. The cable guide element is preferably formed like a belt. A comparable geometry is known, for example, in the case of measuring tapes made of a spring steel or so-called "cracking frogs." As a result of the curvature transverse to the longitudinal extent, the elastic guide element has a stable and a metastable state in the transverse direction that its (stable) curvature is reversed and an opposite curvature sets in. However, with this opposite curvature, the line guide element then assumes a metastable state, so that the line guide element returns to the stable state even with slight, opposite external loading springs back and has the original curvature.

Such a design of the cable guide element for specifying a course of a line between an adjustable window pane and a stationary or stationary vehicle element now has the advantage that this cable guide element which is at least once deflected or bent from the window to the vehicle element, is biased so that a free swing and therefore a any possible striking of the cable guide element to components of the window regulator assembly is almost impossible, without the need for additional guide means for there Leitungsführungsmittei. About the curvature of the cable guide member transversely to its longitudinal extent is also achieved that this has an increased moment of resistance with respect to a spatial axis by which the cable guide element would be bent in the direction of adjacent components of the window regulator assembly. Due to its curvature, the cable guide element can thus be bent more easily with respect to a first spatial axis about which it is in any case deflected between the window pane and the vehicle element than with respect to a spatial axis perpendicular to the first spatial axis.

Accordingly, the cable guide element is preferably fixed to the window pane or to a component (fixedly connected) on the one hand and to the vehicle element on the other hand, that it is bent or deflected in each adjustment position of the window pane and is always taut against a restoring force due to its elasticity. About this bias of the cable guide element is preferably a bending radius of the line guide element, which has a. Most of an adjustment range of the window pane between its two possible end positions almost constant, d. h., Almost unchanged, without the need for separate Führungsmittei - such. B. a sliding block - would have to be provided on the cable guide element.

In preferred embodiments, the cable guide element may be dimensioned and arranged in its length so that the cable guide element in each adjustment position of the window has two mutually parallel and preferably each substantially parallel to the adjustment of the window glass extending sections. The mutually parallel sections merge into one another over a single bending point, wherein a bending radius defined at the bending point, which is defined between the two sections, remains (almost) constant during the adjustment of the window pane solely due to the elasticity of the curved guide element, and this in addition preferably over the entire adjustment range of the window pane.

In preferred embodiments of a window regulator assembly according to the invention it is provided that the cable guide element is deflected exactly once between the two connection points. The cable guide element is thus bent here exclusively about an axis and accordingly has only one individual bending point, regardless of the adjustment position in which the window is present.

The elongated, preferably ribbon-like cable guide element is usually connected to a first end on the window pane or an associated component, such. B. a slidably guided driver of a vehicle window, set while a second end of the cable guide element is fixed to the stationary vehicle element. Accordingly, by adjusting the window pane along its adjustment path, the first end of the line guide element is displaced relative to its second end, so that the course of the elastic line guide element and thus also the course of the line extending thereon and / or along this line must change.

It can be provided that the two ends of the cable guide element are rotated about the longitudinal axis of the cable guide element to each other, so that the cable guide element is at least slightly twisted between its ends. The cable guide element is thus here specifically targeted with a torsional moment, in which the two ends are held rotated around the longitudinal axis of the cable guide element to each other. As a result, the cable guide element in each adjustment position of the window is specifically claimed to bending and torsion, whereby the specification of a defined course between the two Anblndungsstellen is further improved and is also to be achieved, that in an adjustment of the window only a bending point of the cable guide element along its longitudinal extent wandering and consequently the cable guide element is always bent only about a bending axis or - depending on the respective adjustment position of the window pane - about one of a plurality of mutually parallel bending axes.

In this context, it can be provided that the two ends of the cable guide element are rotated by more than 45 °, in particular by approximately 90 ° to each other.

The rotation of the two ends to each other is independent of a possible arrangement of the ends in spaced-apart and parallel virtual planes. As a result of the curvature of the guide guide according to the invention and its elastic design, the relative position of the two ends of the cable guide element is extremely variable, without the risk that the cable guide element is not sufficiently taut and - in the case of an arrangement inside a vehicle door - causing unwanted rattling noises when the door is slammed or when driving. For example, the two ends can be fixed in such a way (in a plane) that the line guide element essentially extends in a plane parallel to the adjustment path of the window pane (compare, for example, the attached FIGS. 4B and 4C). , Alternatively, the two ends can be arranged offset to one another perpendicular to a plane which runs parallel to the adjustment path of the window pane, so that the line guidance element does not extend exclusively in the plane parallel to the adjustment path (compare, for example, the attached FIGS. 4A and 4D) ). Here, the two ends may for example be arranged so that when fully closed raised window the first fixed to the window or an associated component end is located not only above the second fixed to the vehicle element end and offset in side view right or left this, but also forward or backward offset this (see, for example, the attached Fig. 4D). The two ends, which are optionally then additionally rotated relative to each other about the longitudinal axis of the curved line guide element, are arranged offset to each other in the latter case in at least one adjustment position of the window with respect to three mutually perpendicular spatial axes.

For compact accommodation of the cable guide element, for example, within a vehicle door, the second end of the cable guide element is fixed to the vehicle element in one embodiment that the cable guide element extends in at least one (lowered) adjustment position of the window pane with a portion between the window pane and the vehicle element. This is understood to mean that the cable guide element is seen from an outer side with a portion behind the window pane and in front of the vehicle element. Accordingly, during an adjustment of the window pane into its lowermost, lowered adjustment position, part of the window pane is guided past the second end fixed to the vehicle element.

In one embodiment, the length of the cable guide element and the determination of its two ends are selected such that in at least one - preferably the lowest or highest - adjustment position of the window two sections of the once deflected between the two ends guide element run each other at an angle of about 90 ° , In particular, in such an embodiment is then provided that at least one of the ends of the cable guide element is rotatably mounted. For example, for this purpose, the first end fixed to the window pane or to a component connected thereto may be rotatably mounted.

Of course, it is also possible that the second, fixed to the vehicle element end is rotatably mounted thereto.

To simplify the installation of the cable guide element, this is preferably fixed with one end via a latching connection on the window pane, an associated component and / or on the vehicle element. For this purpose, preferably at least one locking lug is provided, which engages in a recess or opening in order to lock the respective end of the cable guide element on the window pane or a component connected thereto or on the vehicle element.

In one variant, an end piece is provided for this purpose on the window pane or the vehicle element, which has an elastically mounted latching hook with a latching nose with which the end of the line guide element engages. For this purpose, for example, one end of the cable guide element can be clipped into such an end piece.

Such an end piece can also be formed, for example, by a driver connected to the window pane and displaceably guided along the adjustment path, or fixed thereto, so that the cable guide element can be clipped onto the driver in a simple manner during assembly.

In order for the line guide element of the line leading thereto between its two connection points to specify a desired course during the adjustment of the window pane, this line must be connected to the line guide element. In this context, different possibilities are conceivable. Thus, the at least one electrical line in the material of the cable guide element - at least partially - be embedded. Here, the line guide element is preferably made of a plastic material. A further variant provides that the cable guide element has an electrically conductive layer as an electrical line, in particular such that the electrically conductive layer is also curved transversely to the longitudinal extent. Further it can be provided that the at least one line is laid along at least one section along the cable guide element and connected thereto.

In principle, the three variants shown above can also be combined with one another. In the course of a simple production, however, it is preferred to select only one of the variants presented above in order to provide a connection between the line and the line guide element.

Regardless of course, it is also conceivable to lead several lines via a single line guide element together and parallel to one another between two connection points on the window pane on the one hand and a stationary vehicle element on the other hand.

In a laying of a line along the line guide element is provided in a Au sf u r n gsvari ate to use at least one separate connector for this purpose, which is fixed to the cable guide element. Such a connector may for example in the manner of a staple engage around a portion of the line and be angekackert on the cable guide element. An alternative variant provides that the connecting piece is fixed to a portion of the line or is formed thereon and the connecting piece -. B. via a plug - is plugged into the cable guide element, which for this purpose has at least one insertion opening.

In another variant, it is provided that the line guide element has at least one passage opening, preferably a plurality of passage openings arranged one behind the other along the longitudinal extension direction of the line guide element, through which the line is guided. Thus, the line may be laid in a plurality of loops on the cable guide element along a plurality of consecutively arranged through holes, whereby the line is fixed without additional fastening means on the cable guide element and the line follows the course of the cable guide element.

In a further variant, the cable guide element forms at least one retaining opening into which a section of the cable is clipped in order to connect the cable to the cable guide element. Preferably, the line guide element has a plurality along its longitudinal extent successively arranged holding openings on to connect the line at different points with the cable guide element without tools.

A further variant provides that the at least one line is glued to the cable guide element at at least one connection point.

In all the above-mentioned embodiments, it is preferred that the line guide element is formed like a strip, for example as a plastic strip or spring steel strip.

Basically, it should be noted at this point that the line can be formed by a single elongate electrical conductor or a single cable. Likewise, the line may have insulation with which an electrical conductor is sheathed. Alternatively or additionally, signals and / or current can be guided to the window pane via a metallic line guide element so that the line guide element itself forms a line or a part of a line, at least in sections.

Furthermore, the second attachment point may be defined on the vehicle element, for example, by a passage opening, through which the line is guided from one side of the vehicle element to another side of the vehicle element. Alternatively, a second attachment point may be defined by an electronic component attached to the vehicle element to which the line is connected.

The stationary vehicle element is also preferably a carrier element, for. Example in the form of a door module carrier, are arranged on the functional components of a vehicle window regulator for adjusting the window pane. Further advantages and features of the present invention will become apparent in the following description of exemplary embodiments with reference to the figures.

FIG. 1 shows a side view of a (rear) motor vehicle door KT in which a carrier element in the form of a door module carrier T can be seen through a cutout in an outer door panel. This door module carrier T is part of an exemplary embodiment of a window regulator assembly according to the invention and here carries functional components of a motor vehicle window regulator by means of which a window pane F is adjustable along a predetermined adjustment path, ie can be lowered and lifted. The door module carrier T, which is embodied in a planar manner and extends essentially in an xz-plane, can moreover be provided for separating a wet space defined between an outer door panel and the door module carrier T from a drying space facing the vehicle interior.

On the door module carrier T, a guide rail 1 is provided, on which in known manner, a driver 2 slidably guided and along the guide rail 1 via a drive device not shown here is adjustable. The driver 2 is connected to the window pane F, here on a lug-like manner on the lower edge of the window pane F projecting connecting section A, so that via a displacement of the driver 2 along the guide rail 1, an adjustment of the window F occurs.

The window pane F in the present case has a switchable glazing. so that the window F appears cloudy or darkened, for example, in a first circuit state and makes it difficult to see inside the vehicle and / or largely impermeable to sunlight, but can assume a second circuit state by applying an electrical voltage and can be explained. For example, the window pane F may have a so-called PDLC (Polymer Dispersed Liquid Crystal) glazing or so-called SPD (Suspended Article Devices) glazing. Alternatively or additionally, the window pane F heating elements, for. B. in the form of heating wires have.

Both for the switchable glazing and for any heating elements, it is necessary to introduce a line to the adjustable window pane F, to the window pane F to a voltage source and / or a control and / or To connect control electronics, which is arranged on the door module carrier T. Such a line is thus coupled to the window pane F and extends to a second connection point on the fixed door module carrier T. At this second connection point, the line can be connected, for example, to an electronic control unit arranged on the door module carrier or through a passage opening of the door module carrier T from one the door outer skin facing outside of the door module carrier T to a vehicle interior facing the inside of the door module carrier T extend. All that is decisive is that the line is in communication with a vehicle element resting on the window pane F, here the door module carrier T.

Due to the required connection of the line to the adjustable window pane F on the one hand and to a stationary component there is basically the difficulty to guide the line defined and to ensure that even with an adjustment of the window F the line is not damaged and does not produce unwanted rattling noises become when the vehicle is moving or the vehicle door KT is relocated.

In order to ensure in the present case a defined guidance of such a line in all adjustment positions of the window pane F, a single strip-like design guide element 3 is provided, which predetermines the course of a line arranged here or herein during an adjustment of the window pane. In the present case, the cable guide element 3 is optimized with respect to its geometry and material properties that any additional rattle between its two ends 31, 32 any rattling noises are reliably avoided and the cable guide element 3 is not bent as desired due to the adjustment of the window pane F, but always a predetermined course having. For this purpose, the line guide element 3 is formed for example as a plastic band or spring steel strip and arched transversely to its longitudinal extent, so that the line guide element 3 has a curvature in cross section. This is again clarified, for example, in the perspective view of FIG.

In addition, the cable guide element 3 is formed elastically in such a way that the cable guide element 3 is endeavored, due to its elasticity, to maintain its curvature and to extend in a straight line. Accordingly, the curved cable guide element 3 in a proper arrangement and connection of its two ends 31, 32 on the one hand with the window pane F and on the other hand with the door module carrier T against an inherent restoring force once bent or deflected and here by about 180 °.

Due to the curvature of the cable guide element 3 - comparable to a spring steel strip in a tape measure or in a so-called "crackle frog" - the cable guide element 3 has a larger moment of resistance with respect to a first transverse to its longitudinal axis bending axis than with respect to a second bending axis to the bending of the cable guide element 3 takes place between its two ends 31 and 32 in its course between the door module carrier T and the window pane F.

The arrangement of the two ends 31 and 32 of the cable guide element 3 is further chosen so that over the entire adjustment of the window pane F between a fully raised and a maximum lowered adjustment a bending radius between the over a bending point merging into each other sections of the cable guide element 3 remains almost constant , Thus, the two ends 31 and 32 relative to the transverse to the adjustment of the window pane F and parallel to the flat door module carrier T extending spatial direction x only slightly offset from each other, so that the two interconnected via the bending sections of the cable guide element 3 to this spatial axis z and parallel to each other. The first end 31 of the cable guide element 3 connected to the window pane F is displaced exclusively along the spatial axis z. During an adjustment of the window pane F, in this case the first end 31 is displaced relative to the second end 32, but the bending point of the cable guide element 3 only seems to travel along the spatial axis z and thus parallel to the adjustment direction of the window pane F, since due to the geometry of the line guide element 3 and its tensioned state a (further) bending or even buckling in the direction of the door outer panel or the door module carrier T is prevented.

2A and 2B, a second embodiment of a window regulator assembly according to the invention is shown, wherein, in contrast to the embodiment of FIG. 1, the arrangement of the cable guide element 3 is slightly changed. Again, the line guide element 3 is fixed with its first end 31 to the connecting portion A and thus directly to the window pane F and with its second end 32 on the door module carrier T. Via a bending point 33, two mutually parallel sections of the simply deflected or curved line guide element 3 continue to merge, so that a first section of the line guide element 3 runs parallel to a second section of the line guide element 3 from the first end 31 to the bending point 33 extending from the bending elite 33 to the second end 32.

The band-like cable guide element 3, which is curved transversely to its longitudinal extension, on or in which a line is provided for transmitting current and / or circuit signals is here laid in such a way that its curvature in the first section (from the first end 31 to the bending point 33) in the direction of the door module carrier T. Further, the second end 32 is fixed here on the door module carrier T at a position offset from the guide rail 1, so that the window pane F is partially guided past the second end 32 during lowering and the second section of the cable guide element between the bending point 33 and the second end 32 extends, at least partially behind the window F on the door module carrier T along.

With the figures 3A and 3B, a further variant of a window regulator assembly according to the invention is illustrated, in which compared to the embodiment of Figures 2A and 2B, the first end 31 of the cable guide member 3 is rotatably mounted on the connecting portion A of the window pane F. Thus, here a rotary bearing DL1 is provided for the first end 31, so that the cable guide element 3 is pivotable at its first end 31 about an axis perpendicular to the planar door module carrier T spatial axis y. As a result of this pivotability on the pivot bearing DL1 changes in this embodiment, in contrast to the previous embodiments, a bending radius between the two sections of the cable guide element, the immovable on the door module carrier T as in the embodiments of the preceding Figures 1 and 2A - 2B, here at a fixed bearing FL2, is fixed.

When the window pane F is lowered from the completely raised adjustment position according to FIG. 3A, the first end 31 of the line guide element 3 is displaced relative to the fixed second end 32. Here, the section of the line guide element 3 extending from the first end 31 to the bending point 33 is pivoted, while the section of the line guide element 3 extending from the bending point 33 to the second end 32 is due to the arched design and the elasticity of the cable guide element 3 thereby only parallel to the adjustment of the window pane F (and parallel to the guide rail 1) is elongated. In a maximum lowered, lowermost adjustment position of the window pane F according to FIG. 3B, the first section of the line guide element 3 then extends from the rotatably mounted end 31 at an angle of approximately 90 ° to the second section of the line guide element 3, which is substantially parallel to the Adjusting path of the window pane F (along the direction of space z) extends from the lying behind the window pane F end 32 in the direction of the bending point 33.

FIGS. 4A-4D and 4E-4G illustrate different variants for the arrangement of a line guide element 3 corresponding to the preceding FIGS. 1, 2A-2B and 3A-3B, which is shown in detail in FIG. 5 in an unloaded and unassembled state. In this case, Figures 4A - 4D show a total of eight different variants, as the ends 31, 32 with respect to the three mutually perpendicular spatial axes x, y, z to each other on the window pane F or the driver 1 on the one hand and on the door module carrier T on the other. FIGS. 4E-4G in turn show examples of different variants for mounting the respective ends 31, 32.

In FIG. 4A, two variants 1a and 1b are initially compared with each other, in which the two ends 31 and 32 are arranged relative to one another such that the line guide element 3 is bent exclusively around an axis parallel to the spatial direction x and accordingly the two ends 31 and 32 only relative to the spatial axis y are mounted offset to each other (depending on the current adjustment position of the window F, the two ends 31, 32 are also offset with respect to the (vertical) space axis z to each other).

The variant la shows an orientation of the cable guide element 3, in which the curvature of the cable guide element 3 in the extending away from the second end 32 portion in the direction of the door module carrier T has, so the curved side facing the door module carrier T. In the variant Ib, in contrast, the cable guide element 3 is oriented so that in this section, the curvature points away from the door module carrier T and consequently the curved side of the cable guide element in this section is remote from the door module carrier T. In FIG. 4B, two variants IIa and IIb show the course of a cable guide element 3 bent over by 180 °, whose single bending axis is parallel to the spatial direction y and thus perpendicular to the bending axis of variants 1a and 1b of FIG. 4A. The two ends 31, 32 thus lie in each case in a common XZ1 or XZ2 plane, which is preferably parallel to an adjustment plane of the window pane F.

In the case of the two variants IIIa and IIIb shown in FIG. 4C, the two ends 31, 32 of the line guide element 3 continue to lie in the same virtual XZ1 or XZ2 plane. In addition, here again the line guide element 3 is bent or deflected, as in the variants IIa, IIb of FIG. 4B, around a bending axis parallel to the main direction y. In addition, however, the two ends 31 and 32 are rotated by 90 ° relative to one another about the longitudinal axis of the cable guide element 3, so that the cable guide element 3 is subjected to a torsional moment when it is intended to be fixed to the window pane F or to the driver 1 and the door module carrier P. is.

In a refinement based thereon according to the variants IVa and IVb illustrated in FIG. 4D, the two ends are again rotated by 90 ° relative to one another about the longitudinal axis of the cable guide element 3 and thus the cable guide element 3 is twisted. In addition, the two ends 31, 32 are mounted offset in relation to one another both in the spatial direction y and in the (horizontal) spatial direction x, so that an intended bending axis of the simply bent cable guide element is essentially at an angle of 45 ° to the (horizontal) spatial direction x and at an angle of 90 ° to the (vertical) spatial direction z.

With the figures 4E, 4F and 4G different variants for fixing the ends 31, 32 are exemplified.

Thus, according to FIG. 4E, both ends 31, 32 can be fixed to the respectively associated component of the window regulator assembly and fixed in each case via a fixed bearing FL1 or FL2. According to FIGS. 4F and 4G, however, provision can also be made for only one end 31 or 32 to be fixed via a fixed bearing FL1 or FL2, while the other end 32 or 31 is rotatably mounted via a rotary bearing DL2 or DL1. FIGS. 6A to 6D illustrate different cross-sectional shapes for a cable guide element 3.

In the variants of FIGS. 6A, 6B and 6C, in each case at least one line in the form of a round conductor 301 or in the form of a flat conductor 303a, 303b is embedded in the material of the line guide element 3, so that the curved line guide element 3 forms a preferably insulating sheath 300 provides the respective lines 301, 303a, 303b. In the embodiment variant of FIG. 6A, the cable guide element 3 with its arcuate cross-section in the cross section has a plurality of round conductors 301 embedded in the casing 300, via which current and / or circuit signals can be transmitted to the window pane F. In the embodiment variant of FIG. 6B, in addition to a plurality of round conductors 301, a curved strip-shaped or wall-like reinforcing element 302 is embedded in the casing 300. In this case, the casing 300 can be made of a plastic material, for example, and the reinforcing element 302 in particular for introducing the desired elasticity and rigidity from a spring steel.

In the embodiment of FIG. 6C, two curved flat conductors 303 a and 303 b, which are stacked one above the other and are insulated from one another by the insulating sheath 300, are embedded in the line guide element 3.

The variants of FIGS. 6A to 6C thus illustrate the different possible variants for embedding an electrically conductive conductor within an (insulating) sheath 300 of the cable guide element 3. In particular, in these embodiments, it is preferred that the cable guide element 3 by extrusion with the internal electrical Ladders 301, 303a, 303b is made.

In the variant embodiment of FIG. 6D, two flat conductors 303a 'and 303b' are provided on an outer side of the cable guide element 3 and on an inner side of the cable guide element 3 and extend over the entire width and length of the cable guide element 3. The two electrically conductive flat conductors are separated 303a ', 303b' through an insulator layer 300 'of the cable guide element 3 lying between them. The sheath 300 and / or the insulator layer 300 'are preferably made of a plastic material, more preferably of a fiber reinforced plastic material. The round and flat conductors 301, 303a, 303a ', 303b and 303b' may be made of copper, for example.

FIG. 7 illustrates, in a cross-sectional view, a further embodiment variant for a cable guide element 3 *, in which two round conductors 301 are not embedded in the material of the cable guide element 3 *. In contrast, the round conductors 301 are fixed in a lateral connection piece 304a * or 304b *, for example, can be formed on the respective round conductor 301. The two lateral connection pieces 304a * and 304b * are mounted on a curved middle part 300 * of the line guide element 3 and here preferably attached to one longitudinal side, so that a lateral connection piece 304a *, 304b * engages around a longitudinal edge of the middle part 300 * of the line guide element 3 *.

In the embodiment variants of FIGS. 8A and 8B, a middle part 300 * has centrally, that is to say with the same distance from the longitudinal edges of the middle part 300 * a plurality of through openings O arranged one behind the other along the longitudinal extent of the line guide element 3 *. At each of these through holes O, a central connector 304 * (FIG. 8A) or 305 * (FIG. 8B) is fixed, in which two round conductors 301 are fixed with at least one portion. Here, too, the connecting pieces 304 *, 305 * can be integrally formed on the respective round conductors 301, so that the connecting piece 304 * or 305 * can then subsequently be mounted on the line guide element 3 * with the round conductor sections embedded therein.

The central connector 304 * of Fig. 8A has for this purpose a single connector 3040 *, via which the central connector 304 * inserted into a through hole O and can be latched thereto. The connecting piece 304 * is designed so that in the mounted state, both round conductors 301 run alongside one another and parallel to one another on one side of the line guide element 3 *.

In the embodiment variant of FIG. 8B, the connecting piece 305 * has two attachment parts 3051 * and 3052 *, which are arranged on different sides of the line guidance element 3 *. The two attachment parts 3051 * and 3052 * are connected to each other via a connecting web 3050 *, which is a Passage opening O in the line guide element 3 * passes through. This connecting web 3050 ^* is, for example, integrally formed on one of the attachment parts 3051 *, 3052 *, so that the one attachment part, for example the attachment part 305, can be mounted on the routing element 3 * from one side, by the connecting web 3050 * the passage opening O be upheld. Subsequently, then the other attachment 3052 * is attached from the other side of the line guide element 3 * forth on this connecting web 3050 *, so that the thus formed central connector 305 ^* via its connecting web 3050 * on the cable guide element 3 * is positively fixed.

In FIGS. 8C and 8D, different shapes for a (plug-in) opening 01 or 02 for a connecting piece 304 * or 305 * are respectively illustrated in plan view. The openings 01, 02 are in each case at a distance d along the longitudinal extension line guide element 3 * arranged one behind the other, so that a determination of the circular conductor 301 on the cable guide element 3 * over multiple connectors 304 * or 305 * is easily possible. By way of example, the opening 01 of FIG. 8C has a rectangular shape and the opening 02 of FIG. 8B has a circular shape. FIGS. 9A and 9B show a plan view and a sectional view of a further embodiment variant of a ribbon-shaped cable guide element 3 **, in which a middle part 300 ^** - in analogy to the embodiment of FIG. 8D - several along the longitudinal extension direction of the cable guide element 3 * * has successively arranged openings 01. In the present case, however, no separate connection piece on the line guide element 3 ** is fixed for connection to a line via these passage openings 01. Instead, a line 4 is laid with at least one internal flat or round electrical conductor via these through holes 01 in loops on the cable guide element 3 along. In this case, the line 4 is guided alternately from one side of the line guide element 3 ** to the other side of the line guide element 3 **.

By way of example, the sectional view of FIG. 9B shows how the line 4 is guided in a section from a lower side US of the ribbon-like line guide element 3 ** through a first through-opening 01 to an opposite upper side OS and then over a second in the longitudinal direction of the line guide element 3 ** behind through hole 01 of the Top OS is led to the bottom US. By such a threading of the line 4 at the through holes 01 and the longitudinal axis of the cable guide element 3 along the line 4 can be set without additional fasteners and without tools on the cable guide element 3 **.

A further variant for the tool-free fixing of a line 4 to a line guide element 3 ** is shown in FIGS. 10A and 10B. In this case, the line guide element 3 ** forms on a (top) side a plurality of angled holding sections 306 ** arranged one behind the other along its longitudinal extent. These holding portions 306 ** are each web-like and here obliquely on the cable guide element 3 ** out. The holding sections 306 ** respectively define a holding opening 3060 ** in accordance with the sectional representation of FIG. 10B, into which a section of the line 4 can be simply clipped. In this way, the line 4 can be held in a form-fitting manner on the line guide element 3 "via the holding sections 306 **.

A further variant is illustrated with FIGS. 11A and 11B in order to lay a line 4 along a line guide element 3 ** and to connect it to it. It is provided here, the line 4 at a plurality of connection points V along the longitudinal extent of the line guide element 3 ** stick.

FIGS. 12A-12B and 13A-13B illustrate possible further developments in order to fix an end 31 or 31 ** of a cable guide element 3 or 3 ** on the window pane F or the door module carrier T via a latching connection. By way of example, in each case the end 31 or 31 ** of a cable guide element 3 or 3 ** to be displaced with the window pane F is shown.

In the embodiment of FIGS. 12A and 12B, a line guide element of FIGS. 9A-9B, 10A-10B or 11A-1 1B is latched at its end 31 * to the driver 2 or an end piece 5 to be mounted separately on the window pane F. For this purpose, the end 31 ** of the line guide element 3 ** has a conically tapered end region 31 1 ** in order to be able to more easily introduce the end 31 ** into an insertion opening 50 of the driver 2 or of the end piece 5. In an accessible via the insertion opening 50 interior of the driver 2 and the end piece 5, an elastically mounted latching Marks is provided with a latching nose 51. This latching hook snaps with its locking lug 51 into a recess 310 ** provided at the end 31 ** and formed behind the chronically running end region 311 **, when the End portion 311 ** sufficiently far into the driver 2 and the tail 5 was introduced. In this way, a simple tool-free fixing of the end 31 ** of the cable guide element 3 ** can be achieved, so that the cable guide element 3 ** can be easily moved and fixed manually during assembly of the window regulator assembly.

In the embodiment of FIGS. 13A and 3B, an end piece 6 is latched to the end 31 of the line guide element 3 and the end 31 is fixed to the window pane F or the driver 2 via this end piece 6. In this case, the end piece 6 has a substantially rectangular base 60, of which a connecting pin 61 and, on the other hand, a latching hook 62 protrude on one side. The connecting pin 61 is cylindrical in this case and has a radially projecting short radial web 310 on it. Through this radial web 62, the end piece 6 can engage according to a key-hole principle in only one orientation to the end 31 of the cable guide element 3 in an associated mounting hole 312 at the end 31.

On the elastically mounted on the base 60 latching hooks 62 a latching lug 620 is formed, which can snap in the fixed via the radial web 610 and mounting hole 312 alignment of the end piece 6 to the end 31 in a further attachment opening 313 at the end 31 of the cable guide element 3. Again, therefore, the connector 6 is tool-free connectable via a latching connection with the end 31 of the cable guide element 3. In this way, the cable guide element 3 can be quickly and easily connected to the end piece 6, which in turn is fixed to the driver 2 or window pane F before or after the connection with the cable guide element 3.

Instead of a latching connection, for example, it may also be provided to provide one end 31, 31 **, 32 of a line guide element 3, 3 *, 3 * ^* with only one through opening and through this through opening and one further opening on the respective component on which the End 31, 31 **, 32 set is to guide a fastener - such as a locking bolt - to fix the end 31, 31 2 *, 32 on the respective component (window pane F, driver 2 or door support module T).
