[0001] Multi-part driver and assembly process

[0002] Description

[0003] The proposed solution concerns in particular a driver for a vehicle window regulator.

[0004] Vehicle window lifters of a window lift system can generally be designed with either a single-strand or a double-strand design. In a single-strand vehicle window lifter, only one guide rail is provided, along which a driver is slidably guided to adjust a window pane, i.e., to raise and lower it. To increase the rotational rigidity of a single-strand vehicle window lifter, it is already known to provide two guide profiles on the guide rail, for example, by stamping, on which one driver is slidably held. The two guide profiles are then formed, for example, on opposite longitudinal sides of one guide rail.

[0005] To attach the driver to a corresponding guide rail during installation of the vehicle window regulator, the driver typically had to be pushed onto the guide rail from one end. A (rail) end piece could then be subsequently attached to the guide rail. For example, the rail end piece is connected to the guide rail by welding or riveting. To facilitate installation, it has already been proposed in practice to simply attach an end piece to a guide rail for a single-strand vehicle window regulator. For example, the guide rail is made of metal and the end piece is made of a plastic material.

[0006] However, there is still a need to further simplify the installation of vehicle window regulators, especially vehicle window regulators for a single-strand window regulator system.

[0007] The proposed solution provides a remedy here. In particular, a multi-part driver for a vehicle window lifter is proposed, which is intended for slidable mounting on a guide rail in order to adjust a window pane. The driver comprises at least a first driver part, a second driver part, and a connecting part. The first driver part is formed with a first guide section and can be mounted via this to a first section of the guide rail formed with a first guide profile. The second driver part, in turn, is formed with a second guide section, via which the second driver part can be mounted to a second section of the same guide rail formed with a second guide profile.The connecting part is provided for fixing the first and second driver parts in order to connect the first and second driver parts to each other after they have been mounted to the guide profiles of one guide rail.

[0008] In a proposed driver, the first and second driver parts can thus be mounted on the guide profiles of a guide rail assigned to them before they have been connected to the connecting part. Only then are the first and second driver parts fixed in their relative position to one another, so that the driver is displaceably mounted on the two guide profiles of one guide rail via the first and second driver parts, and the first and second driver parts are fixed relative to one another via the connecting part and are preferably rigidly coupled, so that they are moved synchronously along the guide profiles when an adjusting force acts on the driver. The multi-part design of the driver makes it considerably easier to mount the driver on exactly one guide rail.

[0009] In principle, it is not necessary for the first and second driver parts to be separate and completely distinct individual components. For example, the first and second driver parts can be connected to one another at least captively before they are mounted on the guide rail, so that the first and second driver parts are held together even before they are mounted on the guide rail. In this case, however, the driver parts are movable relative to one another and their position and alignment relative to one another are not yet fixed, so that the first and second driver parts can be mounted independently on assigned guide profiles of the guide rail. A rigid connection between the first and second driver parts only occurs when the connecting part is attached.In one embodiment, it is alternatively provided that the first and second driver parts are (completely) separated from each other before installation on the guide rail and can be mounted independently of each other on the guide rail. The first and second driver parts are thus provided as individual parts that are only connected to each other after they have been mounted on the guide rail and via the connecting part, in order to form the driver for the vehicle window lifter together with the connecting part.

[0010] The connecting part can generally be a separate component that is independent of the first and second driver parts before the driver is assembled and is intended to be fixed to the first driver part and the second driver part. In such a design variant, the driver is therefore designed in at least three parts and the connecting part can be attached to both driver parts in order to rigidly couple them together when mounted on the guide rail. In an alternative design variant, the connecting part is formed on one of the driver parts and is thus an integral part of one of the driver parts. When the driver parts are mounted on the guide profiles provided for them, the first and second driver parts are then rigidly coupled to one another via the connecting part.For example, the first and second driver parts are fixed to one another via one or more snap connections via the connecting part formed on one of the driver parts.

[0011] In one embodiment, the first driver part, in a guide rail extending along a longitudinal direction, is designed and provided for mounting on the first guide profile transversely to the longitudinal direction. Alternatively or additionally, the second driver part can be designed and provided for mounting on the second guide profile transversely to the longitudinal direction of the guide rail. In such an embodiment, at least one of the first and second driver parts can be mounted laterally on the guide rail and here on the respectively assigned guide profile. Due to the multi-part, optionally at least three-part design of the driver, it is not necessary to slide the driver onto the guide rail from one (upper or lower) end of the guide rail. Via a lateral, ieBy attaching the driver parts transversely to the direction of extension of the guide rail, the installation of the vehicle window lifter can be made more flexible and / or easier, particularly since the guide rail can also be finally formed at its ends and, if necessary, even already mounted before one or more driver parts of the driver are mounted to the associated guide profiles.

[0012] For example, it can be provided that the first driver part is designed and provided for installation on the first guide profile, in which the first driver part is secured to the first guide profile by pivoting the first driver part about a spatial axis parallel to the longitudinal direction. In particular, the first driver part can be designed and provided for installation in which the first driver part is placed on the guide rail transversely to the longitudinal direction and is then secured to the first guide profile by pivoting the first driver part about a spatial axis parallel to the longitudinal direction. In this context, one also speaks of pivoting the driver onto the associated guide profile of the guide rail. The first driver part, by means of which the later finally mounted driver is slidably secured to the respective guide profile, can thus be mounted more easily on its guide profile.Alternatively or additionally, it can be provided that the second driver part is fixed to the second guide profile by pivoting about a spatial axis parallel to the longitudinal direction, if necessary (likewise) after prior attachment transversely to the longitudinal direction to the guide rail - if necessary an attachment along a second mounting direction opposite to a first mounting direction of the first driver part.

[0013] In principle, the first and second driver parts can be provided for mounting on different, first and second longitudinal sides of a guide rail. In such a guide rail, the first guide profile is thus formed on a first longitudinal edge of the first longitudinal side, while the second guide profile is formed on a second longitudinal edge of the opposite second longitudinal side. A guide rail can therefore form a guide profile on the right and left sides, to which one of the driver parts is mounted.

[0014] For the displaceable mounting of the first driver part on the guide rail, the first guide section can be designed and provided for at least partially encompassing a longitudinal edge of the first guide profile. Likewise, the second guide section of the second driver part can be designed and provided for partially encompassing a longitudinal edge of the second guide profile of the guide rail. One of the driver parts or both driver parts therefore have a guide section designed to slide along the guide rail, which is designed and provided for a positive connection with an associated guide track profile on its respective longitudinal edge. In particular, in this context, the driver parts of the driver can be provided for mounting a guide rail, which has two embossed guide profiles on its longitudinal edges for guiding the one - here at least three-part - driver.In particular, a guide profile can have a Z-shaped cross-section.

[0015] In one embodiment, the first and / or second driver part defines a stop, which, in conjunction with a counter-element, is provided for specifying a maximum lowered adjustment position of the window pane. A corresponding stop then protrudes, for example, from a driver body of the respective driver part with respect to an adjustment direction along which the driver is displaceable on the guide rail. If necessary, the respective stop can be made of a material that dampens an adjustment movement before the maximum lowered adjustment position is reached. For example, the stop can be elastically compressible for damping.

[0016] The connecting part, by means of which the first and second driving parts are fixed relative to one another in a proposed driver, can be connectable to the first driving part and / or to the second driving part in a form-fitting and / or force-fitting manner. In particular, in a variant embodiment based on this, it can be provided that the connection of the connecting part to the first or second driving part or to both driving parts can be fixed without additional separate fastening elements, i.e., fastening elements that still have to be mounted on the driving parts and the connecting part. For example, the connecting part can be pluggable onto the first driving part and / or the second driving part and can be fixed via one or more plug-in connections to form-fitting regions of the connecting part on the one hand and to one or more driving parts on the other.

[0017] For example, sections that can be brought into positive engagement with one another are formed on the first driver part and the connecting part and / or on the second driver part and the connecting part. The connecting part can be connected and fixed to the first and / or second driver part via these sections that can be brought into positive engagement with one another after the first and second driver parts have been mounted on one guide rail. For example, the connecting part can be clamped and locked to the first and / or second driver part. In one embodiment, the connecting part or at least one of the driver parts has at least one support section that is provided for supporting the window pane to be adjusted with the driver, e.g. for support on a lower edge of the window pane or on a pane connector fixed to the window pane to be adjusted.Here, the connecting part consequently forms at least one support section, which is designed and intended for the window pane to rest against it with its lower edge or via the window connector (which is provided as an additional intermediate element between the window pane and the driver) when the vehicle window lifter and the window pane to be adjusted via it are installed in the vehicle as intended. Here, the first and second driver parts therefore support the at least three-part driver on the guide profiles of one guide rail, while the connecting part connecting the two driver parts to each other supports the window pane.

[0018] In one embodiment, the driver has at least one adjustment mechanism for adjusting the driver on the guide rail. For example, the driver can comprise at least one adjustment mechanism via which

[0019] - at least one component of the first or second driver part to be connected to the window pane is pivotable about a spatial axis extending at an angle, in particular perpendicular, to the adjustment axis of the window pane relative to at least one base element of the driver and / or

[0020] - at least one component of the first or second driver part to be connected to the window pane is displaceable along a spatial axis running at an angle to the adjustment axis, in particular in a spatial axis running vertically.

[0021] The base element, relative to which the at least one component is adjustable using the adjustment mechanism, has the first or second guide section, via which the first or second driver part is fixed to the guide rail and slidably guided thereon. The adjustment mechanism therefore allows adjustment of a component of the driver, to which the window pane is attached, on the driver already fixed to the guide rail by pivoting and / or sliding this component. On the component to be connected to the window pane, for example, a pane connector element is provided for positively connecting to the window pane or to a pane connector fixed thereto. Alternatively or additionally, the pivotably and / or slidably mounted component comprises the at least one support section mentioned above for supporting the window pane.The base element and the component that can be pivoted and / or displaced relative thereto can, for example, be part of the first driver part or the second driver part.

[0022] In one embodiment, two separate adjustment mechanisms are provided for the first and second driver parts. A first adjustment mechanism can be provided on the first driver part, via which a component of the first driver part, which is to be connected to the window pane (possibly via an additional pane connector), can be pivoted and / or displaced relative to a first base element of the first driver part. A second adjustment mechanism is provided on the second driver part, wherein a component of the second driver part, which is to be connected to the window pane (also possibly via an additional pane connector), can be pivoted and / or displaced relative to a second base element of the second driver part via the second adjustment mechanism.The first and second adjustment mechanisms thus provide an adjustment option on the driver, allowing at least one component connected to the window pane and possibly supporting it to be subsequently adjusted independently of one another on the driver parts with respect to the base element having the guide section. The connecting part is then, for example, fixed to the first base element and to the second base element, so that the position and / or orientation of the components of the first and second driver parts with respect to the associated base elements can still be varied by the adjustment mechanism using the components of the driver to be connected to the window pane, even after the connecting part has been attached to the first and second driver parts.

[0023] When assembling a window lifter comprising the driver, for example, the inclination of the window pane and / or its alignment along a pane plane spanned perpendicular to the pane plane formed by the window pane can be adjusted via first and / or second adjustment mechanisms on the driver and, if necessary, can also be readjusted later.

[0024] Alternatively or additionally, in one embodiment, the driver can comprise an adjustment mechanism via which at least one carrier of the driver can be adjusted parallel to the adjustment axis of the window pane and relative to at least one base element of the driver, wherein the at least one carrier is provided for connection to a traction means of a window lifter (having the driver) and the at least one base element has the first or second guide section for fixing the first or second driver part to the guide rail.

[0025] The carrier of the driver is provided, for example, for the connection of a cable nipple of a traction device designed as a cable pull, via which an adjusting force for adjusting the driver along the guide rail can be introduced into the driver. The carrier can thus, for example, have at least one nipple chamber for securing a cable nipple of the cable pull. By means of an adjustment mechanism of the driver, via which a carrier provided for the connection to a traction device of the window lifter can be adjusted, in particular translationally adjusted, along the adjustment axis relative to a base element having one of the guide sections, the position of the window pane can be adjusted, in particular readjusted, relatively easily in at least one of the two possible end positions, for example during assembly of the window lifter.Such an adjustment option on the driver is advantageous, for example, for adapting the window lifter to a vehicle door or to the vehicle and in particular for adjusting the window position to the body of a vehicle.

[0026] An adjustment mechanism for an adjustable support can, for example, comprise a spindle drive for translational adjustment of the support relative to the at least one base element. Thus, for example, when assembling a window lifter having a driver, a fitter can rotate an adjustment spindle of the spindle drive about its longitudinal axis (running parallel to the adjustment axis of the window pane) in order to adjust a spindle nut of the spindle drive, which meshes with the adjustment spindle and is firmly connected to the support, along the longitudinal axis. Alternatively, the fitter can rotate the spindle nut, which is rotatably mounted on the support, in order to adjust the support along the longitudinal axis of a fixed adjustment spindle.

[0027] Part of the proposed solution is also a single-strand vehicle window lifter which, in addition to a guide rail, comprises a variant of a driver according to the proposed solution, which is movably mounted on one of the guide rails.

[0028] Furthermore, the proposed solution relates to a method for mounting a driver for a vehicle window lifter to a guide rail of the vehicle window lifter. The proposed method includes at least the following steps: - Providing an at least two-part driver comprising a first driver part, a second driver part, and a connecting part,

[0029] - Mounting the first driver part to a first section of the guide rail formed with a first guide profile,

[0030] - Mounting the second driver part to a second section of the guide rail formed with a second guide profile and

[0031] - Fixing the first and second driver parts to each other via the connecting part in order to connect the first and second driver parts already mounted on the guide rail (and held on different guide profiles of the guide rail) to each other, in particular to fix them relative to each other and to rigidly couple them to each other.

[0032] A variant of a proposed assembly method can, of course, be intended for the assembly of a variant of a proposed driver. The advantages and features of a variant of a proposed driver explained above and below therefore also apply to variants of a proposed assembly method, and vice versa.

[0033] In particular, in one embodiment of a proposed method, it can be provided, for example, that

[0034] - the guide rail extends along a longitudinal direction,

[0035] - the first driver part (in particular after the first driver part has been attached to the guide rail transversely to the longitudinal direction) is fixed to the first guide profile, which is formed on a first longitudinal side of the guide rail, by pivoting the first driver part about a spatial axis parallel to the longitudinal direction,

[0036] - the second driver part (in particular after the second driver part has been attached to the guide rail transversely to the longitudinal direction) is fixed to the second guide profile, which is formed on an opposite second longitudinal side of the guide rail, by pivoting the second driver part about a spatial axis parallel to the longitudinal direction - and typically opposite to a pivoting direction for the first driver part, and

[0037] - the connecting part, optionally designed as a separate component of a driver consisting of at least three parts, is attached and fixed to the first and second driver parts already mounted on the guide rail. The attached figures illustrate possible embodiments of the proposed solution.

[0038] Here we show:

[0039] Figure 1A shows a section of a guide rail with two embossed

[0040] Guide profiles for a single driver of a single-strand vehicle window lifter, wherein the guide rail is shown in shortened form and two driver parts of the driver, which here has at least three parts, are mounted independently of one another and spatially separated from one another on each of the guide profiles;

[0041] Figure 1 B shows the guide rail with the

[0042] Driver of Figure 1A, wherein the two driver parts are connected to each other and rigidly coupled via a connecting part of the driver that is plugged onto the two driver parts;

[0043] Figure 2 shows an example of a rear vehicle door of a motor vehicle under

[0044] Illustration of a window lift system with a single-strand window lift, in which a variant of the proposed solution according to Figures 1A and 1B can be used;

[0045] Figure 3 shows a flow chart of a possible embodiment of a proposed assembly method;

[0046] Figure 4A shows a section of a guide rail with another

[0047] Variant of a proposed driver, wherein the two driver parts of the driver, which are connected to one another via a connector part, each have an adjustment mechanism for pivoting a holding element of the respective driver part relative to a base element of the driver part fixed to the guide rail;

[0048] Figure 4B shows, in a view corresponding to Figure 4A, the guide rail with the driver and the pane connector of a window pane to be adjusted, fixed to the driver; Figure 5A shows a section of a guide rail with a further

[0049] Design variant of a proposed driver, on which an adjustment mechanism is provided in order to be able to subsequently adjust a carrier element of the driver having nipple chambers relative to the base elements of the driver parts fixed to the guide rail along the adjustment axis;

[0050] Figure 5B shows, in a view corresponding to Figure 5A, the guide rail and the driver with the disc connector fixed to the driver.

[0051] Figure 2 shows a rear (left) vehicle door T. This vehicle door T is provided with a window opening for an adjustable window pane F. The window pane F can be lowered into a cavity in the vehicle door T along an adjustment direction V2 and raised again in the opposite direction, along an adjustment direction V1. For adjusting the window pane F, a window lift system with a single-strand vehicle window lifter is provided in a cavity provided between an inner door skin and an outer door skin.

[0052] The single-strand vehicle window lifter is mounted on a flat support component A, for example in the form of a door module support. A guide rail 1, made, for example, of a metallic material, is fixed to the support component A. A driver 2 connected to the window pane F is mounted on the guide rail 1 for displacement along the adjustment directions V1 and V2. A drive unit 3—typically an electric motor—with a cable drum is provided for externally powered adjustment of the driver 2 along the guide rail 1. The drive unit 3 transmits an adjustment force for raising or lowering the window pane F to the driver 2 via a flexible traction mechanism in the form of a cable connected to the driver 2.

[0053] In a single-strand window lifter according to Figure 2, it is particularly important that the guide rail 1 with the driver 2 slidably mounted thereon is comparatively rotationally rigid and thus also torsionally rigid in order to ensure a predetermined adjustment path for the window pane F along the adjustment directions V1 and V2. In this context, it has proven advantageous, for example, if two guide profiles are embossed along the length of the individual guide rail 1, on which the individual driver 2 is each guided in a sliding manner. However, with a single driver 2, the difficulty can arise that the driver 2 must be pushed on from one end of the guide rail 1.

[0054] This is not the case with a variant of a proposed driver 2 according to Figures 1 A and 1 B.

[0055] Thus, in the embodiment shown in Figures 1A and 1B, the driver 2 is designed in at least three parts, with first and second driver parts in the form of driver wings 21 and 22 (as first and second parts) and a connecting part 3 (as third part). Before the driver 2 is assembled, the first and second driver wings 21 and 22 are separate, individual parts that are separated from one another and can be mounted independently of one another on the guide rail 1. Each driver wing 21, 22 has a wrap-around section 211 or 221 provided for sliding along the guide rail 1. A wrap-around section 211 or 221 is provided for at least partially encompassing a longitudinal edge of the respective guide profile on longitudinal sections 11 or 12 of the guide rail 1.

[0056] Each longitudinal section 11 or 12 forms a guide profile, via which the adjustment path for the driver 2 is predetermined and which, in the present case, has a Z-shaped cross-section. The guide profile of one section 11 is formed, for example - based on the plan view in Figure 2 - on a left longitudinal edge of the guide rail 1, while the other section 12 is provided on the right longitudinal edge of the guide rail 1. Transversely to a longitudinal direction L, along which the guide rail 1 extends, the two sections 11 and 12 are connected to one another via a base section 13. The longitudinal sections 11 and 12 and the base section 13 are formed integrally with one another.

[0057] As already explained above, the two driver wings 21 and 22 can be mounted independently of one another on the guide rail 1. Each of the driver wings 21, 22 can be attached to the guide profile of one (left) section 11 or the other (right) section 12 assigned to the respective driver wing 21 or 22, transversely to the longitudinal direction L, along different mounting directions on the guide rail 1 - from the left in the case of the first driver wing 21 and from the right in the case of the other driver wing 22. The driver wings 21, 22 can then be pivoted along mutually opposite pivot directions S1, S2 into their end position shown in Figure 1A. The two driver wings 21 and 22 can therefore be attached laterally to the guide rail 1 and pivoted open - once from the left and once from the right.

[0058] Several sections are formed on driver bodies 210, 220 of the driver parts 21 and 22, via which a positive and non-positive connection with a connecting part 23 of the driver 2 is enabled. Via this connecting part, the driver parts 21 and 22, initially present as individual parts on the guide rail 1, can be connected to one another and rigidly coupled to one another in order to provide the driver 2 on the guide rail 1. For example, each of the driver parts 21, 22 has, in a region lying in the adjustment direction V2, a (lower) edge 210R or 220R and a positive-locking region 213 or 223 with an insertion opening. An edge engagement web 232.1R or 232.2R of the connecting part 23 can be inserted onto a respective edge 210R or 220R. A respective edge wrap-around web 232.1 R or 232.2R engages behind the respective associated edge 210R or 220R of a driver wing 21 or 22 when the connecting part 23 has been plugged onto the two driver wings 21, 22 already mounted on the guide rail 1. Furthermore, positive locking pins 233.1 and 233.2 of the connecting part 23 then engage in the insertion opening of the positive locking areas 213 and 223 of the two driver parts 21 and 22.

[0059] Furthermore, contact surfaces 214 and 224—shown here as circular—are formed on the driver parts 21 and 22 at a distance in the longitudinal direction L from the form-locking regions 213 and 223. These contact surfaces 214 and 224 are provided for the engagement of a respective associated contact section 234.1 or 234.2 of the connecting part 23. A respective connecting pin 214a or 224a formed centrally on a contact surface 214 or 224 can engage in a central connecting opening 234.1a or 234.2a of an associated contact section 234.1, 234.2 for the (additional) fixation of the connecting part 23 to the two driver parts 21 and 22.

[0060] If the connecting part 23 is plugged onto the two driver wings 21 and 22 as intended, as shown in Figure 1B, the connecting part is fixed to the driver wings 21, 22 via the above-mentioned sections 210R, 232.1R; 220R, 232.2R; 213, 233.1; 223, 233.2; 214a, 234.1a; 224a, 234.2a, which interact with one another in a form-fitting and force-fitting manner, and the two driver parts 21 and 22 are rigidly coupled to one another via the connecting part 23. The lateral sections of the one-piece connecting part 23 forming the contact sections 234.1, 234.2 and the positive-locking pins 233.1, 233.2 are connected to one another via a rigid central section 230. The central section 230 thus connects the lateral sections of the connecting part 23 connected to the driver wings 21 and 22.In the intended assembled state of the driver 2, the central section 230 of the connecting part 23 consequently extends over a part of the base section 13 of the guide rail 1.

[0061] In order to support the window pane F to be adjusted with the driver 2 at its lower edge in the adjustment direction V2, window support sections 235.1 and 235.2 are provided on the connecting part 23. Thus, in the assembled state of the driver 2, the connecting part 23 not only connects the two driver wings 21 and 22 and secures them relative to each other. Rather, in the assembled state of the driver 2, the connecting part 23 also serves to support the window pane F and connect it to the driver 2.

[0062] The driver wings 21 and 22, which are slidably guided on the longitudinal guide profiles of sections 11 and 12 of the guide rail 1, also provide the connection to the cable pull 4 of the single-strand vehicle window lifter. For example, Figure 1A shows a nipple chamber 2100 for attaching a cable nipple of the cable pull 4 to one of the driver wings 21. This nipple chamber 2100 is closed by the connecting part 23 fixed to the driver wings 21, 22. The cable pull 4 can thus be coupled to the driver wings 21 and 22—without the connecting part 23 being fixed to the driver wings 21 and 22—for the subsequent transmission of an adjusting force for raising or lowering the window pane 1. Only after the cable pull 4 has been connected to the driving wings 21, 22 is the connecting part 23 fixed to the driving wings 21 and 22.

[0063] In the adjustment direction V2, a stop 212 or 222 protrudes from the driver bodies 210, 220 of the driver wings 21, 21. In interaction with a counter element of the vehicle window lifter, e.g., provided on the guide rail 1 or the support component A, these stops 212 and 222 limit the adjustment path of the window pane F to be lowered. For any damping of the adjustment movement before reaching a maximum lowered adjustment position of the window pane F, the stops 212, 222 can be made of an elastically compressible and thus damping material.

[0064] The flow chart in Figure 3 illustrates once again the procedure already explained above for mounting the at least three-part driver 2 to the guide rail 1 with its sections 11 and 12, on each of which a guide profile with a Z-shaped cross section is embossed.

[0065] Thus, in a first step, one of the driver wings 21, 22 is mounted as the “first driver part” either from the right or left onto the respectively assigned guide profile - in the embodiment of Figures 1A and 1B by pivoting up the respective driver wing 21 or 22 - on the guide rail 1. In a subsequent second step S2, the respective other driver wing 22 or 21 is mounted as the “second driver part” from the other direction and thus either from the left or right onto the respective other guide profile, in the embodiment of Figures 1A and 1B, for example, again by pivoting up on the guide rail 1. Subsequently, the first and second driver wings 21, 22 are connected to one another and rigidly coupled in a step S3.For this purpose, the connecting part 3 is attached to the first and second driver wings 21, 22 - if necessary without tools - perpendicular to the longitudinal direction L and perpendicular to the assembly directions running transversely thereto, along which the driver wings 21 and 22 were attached to the guide rail 1 (in Figures 1A and 1B therefore from the front) and is thereby fixed to both driver wings 21 and 22. The assembled driver 2 is then held and slidably guided on the guide rail 1 on both longitudinal guide profiles of the guide rail 1 without the need to be pushed on from one longitudinal end of the guide rail 1, wherein the connection of the driver 2 to the window pane F can take place at the connecting part 23.

[0066] In deviation from the embodiment variant shown, in another embodiment variant of the proposed solution it can be provided that a connecting part is formed on one of the driver wings 21, 22 and is thus an integral part of one of the driver wings 21, 22. One driver wing 21 or 22 is first mounted on the guide profile provided for it. By mounting the other driver wing 22 or 21 on the other guide profile provided for it, the first and second driver wings 21 and 22 are then rigidly coupled to one another via the connecting part. For example, the connecting part formed on one of the driver wings 21 or 22 forms locking openings or locking lugs for this purpose, which lock into corresponding locking openings or locking lugs on the other driver wing 22 or 21 when the further driver wing 22 or 21 is mounted on the guide rail 1, in particular is pivoted onto it.Figures 4A and 4B show a further embodiment of a proposed multi-part - here three-part - driver 2, which is already mounted on the guide rail 1 and in which the two driver wings 21 and 22 are already connected to one another via a connector part 23. Each driver wing 21, 22 of the embodiment of Figures 4A and 4B has an adjustment mechanism 27.1 or 27.2, via which the window pane F fixed to the driver 2 can be subsequently adjusted with respect to a Y-axis that runs perpendicular to the adjustment axis (Z-axis) along which the driver 2 can be adjusted on the guide rail 1 in the adjustment directions V1 and V2.

[0067] Thus, in the embodiment variant Figures 4A and 4B, each driver wing 21, 22 has a driver body 210 or 220, which in the present case is formed by at least three parts, namely a base element in the form of a base plate 210A or 220A, a holding element adjustably mounted thereon in the form of a holding plate 210B or 220B and a bearing element 210C or 220C, via which the holding plate 210B / 220B is adjustably mounted relative to the associated base plate 210A / 220A. A base plate 210A or 220A comprises the first or second guide section 211, 221 for securing the respective driver part 2122 to the guide rail 1 as well as the form-fitting area 213 or 223 for the connection to the connector part 23. Furthermore, nipple chambers 2100, 2200 for connecting the cable pull 4 to the respective driver wing 21 or 22 are also formed on a base plate 210A, 220A.

[0068] A retaining plate 210B, 220B of a driver wing 21 or 22 in the present case each has a pane connector element for fixing the window pane F to the respective driver wing 21 or 22 in the form of a connecting pin 219 or 229. Furthermore, support sections 215.1 / 215.2 or 225.1 / 225.2 are formed on each retaining plate 210B, 220B. Either the lower edge of the window pane F or - as shown in Figure 4B - a lower edge of a pane connecting end 5 fixed to the window pane F can be supported on these support sections 215.1 / 215.2 or 225.1 / 225.2. The connecting pins 219 and 229 can engage in openings on the window pane F or - as shown in Figure 4B - in insertion openings 511 and 512 of the pane connecting end 5.The insertion openings 511 and 512 are formed on a driver connection area 51 of the pane connector 5, while the pane connector 5 is fixed to the window pane F via a pane connection area 50. The holding plates 210B and 220B provided for connecting and supporting the window pane S are each pivotably mounted on an associated base plate 210A, 210B. For this purpose, each holding plate 210B, 220B is articulated to the associated bolt-shaped bearing element 210C or 220C, which is formed on a pivot bearing section 216 or 226 of the associated base plate 210A or 220A. At an upper end of the driver 2, i.e. in the z-direction, each holding plate 21 OB, 220B of the driver 2 is thus pivotably mounted on the associated base plate 21 OA or 220A about a rotation axis D1 or D2 running parallel to the Y-axis.

[0069] At a lower end located in the -z direction, each holding plate 210B, 220B is adjustable in its orientation relative to the associated base plate 210A or 220A via an adjusting element in the form of a threaded bolt 217 or 227. Thus, each threaded bolt 217, 227 is supported by a bolt head on a rear side of the base plate 210A or 220A and extends through the respective base plate 210A or 220A to engage a threaded opening 227 or 228 on the holding plate 210B or 220B, so that by rotating the respective threaded bolt 217 or 227, the lower end of the respective holding plate 210B, 220B can be adjusted in its distance relative to the base plate 210A, 220A. This allows an angle to be set on each driver wing 21, 22, which angle is spanned between the respective base plate 210A, 220A and the holding plate 210B, 220B pivotably mounted thereon.In a possible further development, a longitudinal displaceability of a holding plate 210B or 220B relative to the respective base plate 210A, 220A along the rotation axis D1, D2 (in the y-direction and in the -y-direction) on the bolt-shaped bearing element 210C or 220C can also be provided.

[0070] In the further embodiment of Figures 5A and 5B, an adjustment mechanism 27 is provided on a three-part driver 2 - optionally also in addition to one or both adjustment mechanisms 27.1, 27.2 of the embodiment of Figures 4A, 4B - by means of which adjustment mechanism 27 a carrier 24 of the driver 2 can be adjusted in its position relative to the driver bodies 210, 220 of the two driver wings 21, 22 along the adjustment axis (Z-axis) of the driver 2 when the window pane F is already mounted on the driver 2. The carrier 24 has one or more nipple chambers 240 for the connection to the cable pull 4. By adjusting the carrier 4 with respect to the driver wings 21, 22, the position of at least one nipple chamber 240 of the driver 2 can be adjusted along the adjustment axis Z after the window pane F has already been connected to the driver 2.In the embodiment shown in Figures 5A and 5B, the carrier 24 with the at least one nipple chamber 240 is located, for example, in the space between the two driver wings 21, 22 and is mounted for longitudinal displacement on one of the driver wings - in this case, the driver wing 22 shown on the right. Part of the adjustment mechanism 27 for the longitudinal adjustability of the carrier 24 is an adjusting spindle 271 provided on one of the driver wings 22. A spindle nut rotatably mounted on the carrier 24 meshes with an external thread of this adjusting spindle 271. If this spindle nut is rotated by a fitter, the carrier 24 is displaced upwards or downwards along the adjustment axis Z in the adjustment direction V1 or V2.Alternatively, the adjusting spindle 271 can be rotatable via an adjuster 272 of the adjusting mechanism 27 in order to effect a longitudinal adjustment of the carrier 24 via the spindle nut which meshes with the adjusting spindle 271 but is then fixed to the carrier 24.
