CARRIER FOR A VEHICLE WINDOW REGULATOR

Description

[0001] The proposed solution concerns a driver for a vehicle window regulator that can be connected to a window pane to be adjusted.

[0002] Drivers for vehicle window regulators are widely known in many different designs, for example from DE 202 02 551 U1, US 2017 / 241181 A1, EP 0 208 237 A1 or DE 10 2010 013 945 A1. Such drivers are usually guided on guide rails and connected to the window pane in the area of ​​a lower edge. A flexible traction mechanism, for example in the form of a cable, then usually engages the driver in order to transmit an adjusting force for adjusting the window pane to the driver via the flexible traction mechanism. The driver can then be moved along the guide rail to raise or lower the window pane.

[0003] CN206233747U discloses a driver according to the preamble of claim 1.

[0004] For drivers known from practice, especially for drivers for vehicle window regulators, there is often a need for improvement with regard to different installation and / or installation space situations. For example, there is a regular need for design improvements for a driver to improve the installation of the window pane to the driver, the connection of the window pane to the driver, the connection of a flexible traction device to the driver, and / or the durability of the driver and a window regulator assembly formed thereby.

[0005] Against this background, an improved driver according to claim 1 is proposed.

[0006] A proposed driver comprises a driver body and a pane connection area provided on the driver body, via which the driver can be secured to the window pane to be adjusted. This pane connection area defines a connection gap into which the window pane to be connected is to be inserted with a lower edge, so that the lower edge, when properly connected, lies opposite a base of the pane connection area. With a view to improved assembly of the window pane to the driver and improved connection of the window pane to the driver, it is further proposed that the pane connection area additionally comprise the following: two connecting brackets provided on the driver body, on each of which a locking lug is provided for the positive engagement in a connection opening provided on the window pane and which are each opposite at least one positioning section protruding from the base, wherein, for the assembly of the window pane to the driver along an assembly direction, the connecting brackets on the driver body are elastically displaceable and the positioning sections opposite the connecting brackets each form a guide surface which runs inclined to the assembly direction of the window pane and via which the lower edge of the window pane introduced into the connection gap is guided in the direction of the base.

[0007] A proposed disc connection area thus has two connecting brackets, each with an opposite positioning section forming an inclined guide surface.

[0008] If necessary, the pane connection area may additionally have at least one support section made of an elastic material projecting from the base for supporting the lower edge of the window pane.

[0009] Using the provided positioning section, the lower edge of the window pane, which has already been inserted into the connecting gap of the pane connection area, can be guided in a targeted manner toward the base and thus into a locking position, in which the locking lug of the connecting bracket snaps into the provided connection opening of the window pane. The positioning section can be used, for example, to stabilize the window pane, which has already been inserted into the connecting gap, perpendicular to the installation direction. For example, when the vehicle window regulator is already pre-assembled with the driver, the window pane is typically guided from above to the driver, which is held in an installation position.The lower edge inserted into the connecting gap initially displaces the elastically displaceable connecting bracket transversely to the installation direction until the window pane has been brought close enough to the base of the pane connecting area that the locking lug of the respective connecting bracket can snap into the connecting opening of the window pane. In this context, it has been shown that under certain circumstances, the lower edge of the window pane inserted into the connecting gap can cause a connecting bracket to be displaced an undesirable distance, in particular to be pivoted, and thus the locking lug does not engage with a connecting opening of the window pane. The additional positioning section, which is opposite the connecting bracket, can then be used within the connecting gap to further stabilize the already inserted lower edge of the pane and an edge of the window pane forming the lower edge of the pane.

[0010] With at least one optional support section protruding from the base, it is also possible, after the window pane has been properly mounted on the driver, to ensure that the window pane is elastically supported on the driver at its lower edge. The at least one support section made of an elastic material protruding from the base ensures that the lower edge of the window pane is only supported locally on the base when the window pane has been properly connected to the driver. A window lifter assembly with a driver and window pane can thus be provided, in which the window pane rests with its lower edge only on one or more support sections made of an elastic material protruding from the base.Away from the one or more support sections, the window pane does not rest with its lower edge on the base, so that the lower edge away from one or more support sections is spaced from the base and a narrow gap is present. An elastically deformable support section thus provides a spring travel by which the window pane can be displaced relative to the driver during operation of the window lifter, for example when the window pane is adjusted to an (upper) end position. For example, at least a slight relative movement between the window pane and the driver is permitted via the at least one protruding support section made of elastic material when the window pane moves into a window seal to completely close a window opening.

[0011] In one design variant, the support section at the base of the driver protrudes toward the bottom edge of the pane, which also prevents a switching noise when the window pane is adjusted in the opposite direction. Furthermore, the elastic support section always provides defined support for the pane on the driver, ensuring that the bottom edge of the pane rests firmly on the driver, even during slight tilting movements of the window pane when the pane is lifted.

[0012] According to the invention, the connecting brackets of the pane connecting region can each be elastically pivoted about a pivot axis, wherein the base of the pane connecting region, on which the positioning section is provided, is spaced from this pivot axis. Thus, a spatial offset is provided on the driver between a pivot axis of the connecting brackets provided on the driver and the base, opposite which the lower edge of the pane lies when the window pane is properly secured to the driver. Such a spacing between the pivot axis of the connecting brackets and the base, on which, for example, the support sections for supporting the lower edge of the window pane are provided, can, for example, allow a larger opening angle due to the elastic displacement of the connecting bracket when the window pane is mounted on the driver.

[0013] According to the invention, a respective positioning section of the pane connecting region for mounting the window pane on the driver is also elastically displaceable, in particular relative to the connecting bracket. The positioning section serving to stabilize the lower edge of the pane already inserted into the connecting gap can thus also have a certain elastic displaceability in order to assist in reaching the locking position of the window pane on the driver, in which the locking lug of the connecting bracket then snaps into the connecting opening on the window pane. In this case, the positioning section opposite the connecting bracket can, for example, be pivoted in exactly the opposite direction to the connecting bracket during installation of the window pane, specifically under the effect of the window pane being inserted into the connecting gap with its lower edge along the installation direction.The window pane can thus initially act with its lower edge on the connecting bracket in order to pivot it in a first pivoting direction (e.g., towards an outside). Then, upon further insertion of the window pane into the connecting gap of the driver, the lower edge also elastically displaces the positioning section by being guided along the inclined guide surface of the positioning section. The elastic displacement of the positioning section then occurs opposite to the pivoting direction of the connecting bracket (e.g., towards an inside). The positioning section can thus, in particular - optionally together with the base - be elastically displaceable relative to the connecting bracket.

[0014] According to the invention, a connecting bracket of the pane connecting region is elastically pivotable on the driver body about a first pivot axis, and the positioning section of the pane connecting region is elastically pivotable about a second pivot axis spaced from the first pivot axis. Thus, the first and second pivot axes of the connecting bracket, on the one hand, and of the positioning section, on the other hand, which may run parallel to one another, are deliberately spatially offset from one another along the installation direction of the window pane.In this way, in particular, a successive elastic pivoting of the connecting bracket and the positioning section can be realized depending on the degree of insertion of the lower edge of the disc into the connecting gap of the driver, without having to stiffen the disc connecting area due to the loads acting in different directions for the pivoting of the connecting bracket and the positioning section.

[0015] According to the invention, the two connecting brackets of the pane connection area are each U-shaped, with a recess in the respective connecting bracket being defined by two legs and a head section of a U-shaped connecting bracket connecting the legs. For example, the locking lug of the respective connecting bracket is formed on the head section, so that an elastic displacement of the head section provided with the locking lug is possible via the two legs.

[0016] In a further development, the additional positioning section with its guide surface inclined to the mounting direction is located directly opposite the recess formed in the connecting bracket (transverse to the mounting direction).

[0017] According to the invention, the base, on whose support section, optionally on whose projecting support section made of an elastic material, the lower edge of the window pane is to rest, is formed by a base section of the driver, which projects on the driver body in the direction of the head section of the U-shaped connecting bracket. The formation of the base by a base section can in particular serve to space the base from the pivot axis of the connecting bracket, about which the connecting bracket is elastically displaceable during assembly of the window pane on the driver. Furthermore, an elastic displaceability of the positioning section provided on the base can be integrated via the projecting base section and / or the positioning section is designed to be elastically displaceable precisely on the base projecting like a base.

[0018] It extends at least partially into the recess of the connecting bracket.

[0019] This not only enables a compact design of the driver with connecting bracket and positioning section. Rather, in a possible refinement, the base section extending at least partially into the recess of the connecting bracket also allows a bearing finger or projection for the inserted window pane, additionally provided on the base on the side of the connecting bracket, to be located precisely between the two legs of the connecting bracket. Such a bearing finger or projection, provided on the base section and located between the two legs, can provide (additional) support to the driver transversely to the mounting direction of the window pane when the window pane is properly mounted to the driver.For example, when the window pane is properly installed, a portion of the window pane is located just between the bearing finger or projection and the positioning portion, both of which project from the base formed by the socket portion.

[0020] The positioning section can fundamentally have different geometries and contours. In one embodiment, for example, the positioning section is pin-shaped. Thus, in this embodiment, the extension section can protrude upward from the base in a pin-like manner, based on the intended installed state of the driver.

[0021] In one embodiment, two opposing sides of the connecting gap of the pane connecting region are defined in particular by (on the one hand) the connecting bracket and (on the other hand) a bearing section protruding from the driver body. The at least one connecting bracket and the protruding, for example web-shaped, bearing section thus define the connecting gap into which the lower edge of the window pane is to be inserted in order to connect the window pane to the driver as intended. The positioning section, which is designed with its inclined guide surface, is accordingly additionally provided and only becomes effective once the lower edge of the window pane has already been inserted into the connecting gap in order to ultimately guide the lower edge of the window pane towards the base and thus the locking position for the locking lug to snap into place.

[0022] In principle, more than two connecting brackets can be provided on the driver. Especially for a single-strand window regulator, it is advisable to secure the window pane using two connecting brackets, each equipped with a locking lug, which can then engage in two connecting openings provided on the window pane.

[0023] In a further development based on this, the above-mentioned bearing section is provided precisely between the two connecting brackets. While the connecting brackets then protrude from the driver body on one side of the window pane when the window pane is properly mounted to the driver, the bearing section protrudes on the opposite side of the window pane. Accordingly, a section of the window pane at the lower edge of the window pane is accommodated in a connecting gap defined on the one hand by the two connecting brackets and on the other hand by the bearing section.

[0024] A support section of the pane connection area protruding from the base can be formed, for example, by a soft component. For example, this soft component is injection-molded onto the base. In this case, the base can consist of a hard component. While the optionally injection-molded soft component is thus, for example, elastically compressible, the hard component of the base is comparatively stiff. For example, the base is formed from a thermoplastic material, such as polypropylene or polyamide. The soft component injection-molded thereon, which forms the at least one support section, consists, for example, of a thermoplastic elastomer, such as thermoplastic copolyester.

[0025] In a further development, the support section is formed by a locally protruding thickening of the soft component at the base. The soft component can be provided, in particular, on a base section that extends at least partially into a recess of a U-shaped connecting bracket and / or on a base that has a positioning section.

[0026] In one embodiment of the proposed solution, a proposed driver has at least one fluid guide element for draining fluid from the driver body. The at least one fluid guide element can be part of a fluid guide structure through which fluid is drained from the driver body when the structure is installed as intended as a component of a window lifter.

[0027] With the aid of the fluid guide element, a structure is provided on the driver, in particular formed on the driver body, by means of which structure fluid is discharged from the driver along a flow direction predetermined by the at least one fluid guide element. This includes, for example, the possibility of fluid being directed toward an edge of the driver body via the at least one fluid guide element. Thus, fluid reaching the driver during operation of the window lifter can be selectively discharged via the fluid guide element and, in particular, can be selectively directed away from sections and / or components of the driver and / or the window lifter.For example, the at least one liquid guide element can be used to ensure that liquid originating from the driver, for example water, is guided away from a guide rail that displaceably supports the driver and / or from a traction means fixed to the driver.

[0028] In one refinement, for example, it is provided that the at least one fluid guide element extends with one end beyond an edge of the carrier body. Fluid present on the carrier body can then be guided away from the carrier body via the fluid guide element and drain off at the end of the fluid guide element extending beyond the edge.

[0029] The liquid guide element can, for example, comprise a rib, recess and / or groove provided on the driver body, in particular formed on the driver body.

[0030] In one embodiment variant of the proposed solution, a proposed driver has a traction means connection area for connecting a flexible traction means to the driver body, which has two nipple chambers arranged consecutively along a longitudinal direction. According to the proposed solution, an assembly opening is provided between these two nipple chambers, through which an end section of the flexible traction means can be inserted into each of the nipple chambers. After proper assembly, an adjusting force for adjusting the window pane connected to the driver can be transmitted to the driver via the flexible traction means via the end sections inserted into the nipple chambers and held therein in a form-fitting manner. To facilitate assembly, the assembly opening is further provided with a length, relative to the longitudinal direction, that corresponds to at least half the sum of the lengths of the two nipple chambers.In particular, the assembly opening can be provided with a length, based on the longitudinal direction, which corresponds to at least 0.8 times or at least the sum of the lengths of the two nipple chambers. In this way, for example, two end sections of the traction means, each provided with a spring element, can be inserted one after the other into the nipple chambers via the one common assembly opening without compressing the spring elements.

[0031] Accordingly, in one embodiment, the mounting opening of the traction mechanism connection area can, for example, have a length such that two end sections of the traction mechanism, each provided with a spring element, can be inserted one after the other into the nipple chambers arranged successively along the longitudinal direction via the one mounting opening without compressing the spring elements. For example, in the case of a flexible traction mechanism designed as a cable pull, compression springs, each with a cable nipple, provided for cable length compensation, can be inserted manually (by hand) one after the other through the mounting opening provided between the nipple chambers without any effort via the mounting opening of the traction mechanism connection area. An assembly aid for compressing a compression spring in order to be able to insert it as intended into a nipple chamber on the driver, for example a so-called power pack, is therefore not necessary here.

[0032] In one embodiment, the traction mechanism connection area has a traction mechanism guide channel that is open on at least one side and has a longitudinally extending traction mechanism opening for inserting a section of the traction mechanism into the traction mechanism guide channel. When mounting the traction mechanism to the driver, an end section of the traction mechanism is inserted into the nipple chamber via the mounting opening, with a section of the traction mechanism extending away from the end section being inserted into the traction mechanism guide channel adjoining a nipple chamber via the traction mechanism opening.

[0033] In a further development based on this, a lubrication opening is provided between a traction mechanism opening of a traction mechanism guide channel associated with a nipple chamber and the assembly opening, through which lubrication of the nipple chamber is possible from the outside. For example, the assembly opening, the lubrication opening of a nipple chamber, and a traction mechanism opening for the traction mechanism guide channel adjoining a nipple chamber follow one another along the longitudinal direction.

[0034] To facilitate greasing via the greasing opening, in one design variant the width of the greasing opening is greater than the width of the assembly opening, but smaller than the width of the tension member opening of the tension member guide channel. The reduced width of the greasing opening compared to the assembly opening ensures that a tension member end section, which is inserted into the nipple chamber as intended and may be spring-loaded, cannot be removed from the nipple chamber via the greasing opening. At the same time, the greater width of the greasing opening compared to the tension member opening of the tension member guide channel ensures that greasing the nipple chamber, for example with grease stone, is easier.

[0035] According to the above explanations, a disk connection region can easily be combined with a fluid guide element and / or with a traction mechanism connection region. For example, a traction mechanism connection region can be provided on a driver body of a driver, on which a disk connection region is provided laterally and above the traction mechanism connection region. The disk connection region has two elastically displaceable connecting brackets arranged above and laterally to the disk connection region, each with a locking lug and a positioning section opposite a connecting bracket, as well as at least one base having an elastic support section. At least one fluid guide element can additionally be formed on the driver body in order to guide fluid from the traction mechanism connection region outwards in a targeted manner to an edge of the driver body and to allow it to drain away.The fluid guide element can extend, with respect to the mounting direction of the window pane and / or an adjustment axis of the window pane after proper mounting of the window lifter, just below a connecting bracket on the driver body.

[0036] The attached figures illustrate possible embodiments of the proposed solution.

[0037] Here we show: Figures 1A-1B each in perspective view and looking at different sides a variant of a proposed driver; Figure 2 in side view and in detail the driver with a window pane connected to the driver; Figure 3 in rear view a first phase of assembly of the window pane to the driver; Figures 4A-4D the assembly of the window pane to the driver in the Figure 3consistent view in further phases; Figure 5 in enlarged scale the driver of the Figures 1A and 1B with a view of a traction mechanism connection area of ​​the driver; Figures 6A-6C various views of the driver of the Figures 1A and 1B illustrating a fluid guide structure provided on the follower; Figure 7 schematically shows a window regulator assembly in which a proposed follower is used.

[0038] The Figure 7illustrates an example of a window lifter for a motor vehicle. This window lifter comprises a window lifter assembly FH with a displaceably guided driver 1, to which a window pane F is connected. The driver 1 is coupled to a flexible traction means in the form of a cable 2, which is adjustable via a plurality of deflection elements U1, U2, for example in the form of rotatably mounted cable pulleys, by means of a drive A. The drive A, which, like the deflection elements U1 and U2, is arranged on a support component T, drives a cable drum 3 via a motor MA. By winding and unwinding the cable 2 onto and from the cable drum 3, the driver 1 can be adjusted longitudinally. The window pane F, which is guided laterally in pane guides G1 and G2, is then raised or lowered, depending on the direction of rotation of the cable drum 3. In the Figure 7In the single-strand window lifter shown, the driver 1 can be guided displaceably along a guide rail which is formed by the support component T or is fixed to the support component T.

[0039] A variant of the driver 1 according to the proposed solution is shown in the Figures 1 to 6C shown.

[0040] The driver 1 has a driver body 10, on which, in particular, rail grips 10.1, 10.2 are formed for displaceably mounting the driver 1 on a guide rail. These rail grips 10.1 and 10.2 are provided in a central region of the driver body 10 on an inner side 1B of the driver 1.

[0041] At an upper end of the driver 1, relative to the intended installed state, the driver body 10 forms a disc connection area 11 with two elastically displaceable connecting brackets 11A and 11B. The connecting brackets 11A and 11B projecting upwards on the driver body 10 are, for example, in accordance with the Figures 1A and 1B each U-shaped. Each connecting bracket 11A, 11B is elastically displaceable on the driver body 10 via two legs of this U-shape, so that a head section 11KA or 11KB connecting the two legs can be pivoted when the window pane F is mounted on the driver 1. A locking lug 110A or 110B is formed on each of these head sections 11KA, 11KB, which, when the window pane F is properly attached to the driver 1, snaps into a connecting opening in the window pane F in order to secure the window pane F and the driver 1 to one another.

[0042] A bearing section in the form of a bearing web 11C extends between the two connecting brackets 11A and 11B. Together with the connecting brackets 11A and 11B, the central bearing web 11C defines a connecting gap S at the pane connecting area 11, into which the window pane F is inserted with a lower edge K (compare Figure 2 ) is to be inserted in order to fix the window pane F to the driver 1. When the window pane F is connected as intended, the two connecting brackets 11A and 11B are located on one side of the window pane F, while the bearing web 11C is located on an opposite side of the window pane F. When installed as intended, for example, an outer side 1A of the driver 1 with the connecting brackets 11A and 11B faces an outside of a motor vehicle, while the inner side 1B with the bearing web 11C faces an interior of the motor vehicle.

[0043] In the intended assembled state, the lower edge K of the window pane F rests against a base 113A, 113B of the pane connecting area 11, which base defines a lower end of the connecting gap S. A base 113A, 113B is provided in the area of ​​one of the connecting brackets 11A, 11B and is formed on a base section 114A or 114B, which extends into a recess OA or OB formed between the legs of a connecting bracket 11A or 11B. A base 113A or 113B is spaced upwards above the base section 114A or 114B relative to a pivot axis D1 of a connecting bracket 11A or 11B, about which base a connecting bracket 11A or 11B can pivot (outwards) along a pivot direction R1 when the window pane F is mounted on the driver 1, cf. Figures 4A to 4C .

[0044] On each base 113A or 113B associated with a connecting bracket 11A or 11B, a bearing finger 111A or 111B associated with the outer side 1A is formed as part of the disc connecting region 11. Furthermore, a positioning section in the form of a pin-like catch hook 112A or 112B protruding from the base 113A or 113B is provided opposite each connecting bracket 11A or 11B. Each of these catch hooks 112A, 112B contributes to the stabilization of the window pane F inserted into the connecting gap S during assembly and guides the (pane) lower edge K via a guide surface 1120A or 1120B in the direction of the base 113A or 113B and thus into a designated locking position in which the locking lugs 110A and 110B of the connecting brackets 11A and 11B can snap into the corresponding connecting openings of the window pane F.A guide surface 1120A, 1120B of a catch hook 112 A or 112 B is in each case inclined to a mounting direction M, along which the window pane F is to be inserted (from above) into the connecting gap S.

[0045] As shown by the Figures 3 and 4A to 4D For various phases of the assembly of the window pane F to the driver 1, the window pane F inserted into the connecting gap S initially displaces the connecting brackets 11A and 11B with its lower edge K, running onto the locking lugs 110A and 110B. The connecting brackets 11A and 11B are thereby initially displaced outwards together with the respective base 113A, 113B relative to the rest of the driver body 10, which is already held on a guide rail via the rail grips 10.1, 10.2 ( Figure 4A ). The connecting brackets 11A and 11B then pivot elastically outwards around their pivot axis D1 along the pivot direction R1 ( Figure 4B). To ensure that the window pane F does not pivot the connecting brackets 11A and 11B further outwards when approaching further in the direction of the bases 113A and 113B, and thus possibly fails to engage with the connecting brackets 11A and 11B, the lower edge K of the window pane F, when further displaced along the mounting direction M, runs onto the guide surfaces 1120A and 1120B of the catch hooks 112A and 112B, which are opposite the connecting brackets 11A and 11B ( Figure 4C ). The lower edge K of the disc F is guided downwards in a defined manner towards the bases 113A and 113B into the designated locking position via the inclined guide surfaces 1120A and 1120B ( Figure 4D ).

[0046] As can be seen in particular from the Figures 2 and 4C to 4DAs illustrated, in the present case, an elastic displaceability of the catch hooks 112A and 112B relative to the connecting brackets 11A, 11B is permitted. Thus, each catch hook 112A, 112B can pivot inwards opposite to the connecting brackets 11A and 11B and relative to the connecting brackets 11A and 11B along a pivot direction R2 under the action of the lower edge K introduced further (downward) into the connecting gap S along the assembly direction M. A pivot axis D2 of the catch hooks 112A and 112B is spaced apart from the pivot axis D1 of the connecting brackets 11A and 11B by a distance a via the base sections 114A and 114B.

[0047] If the lower edge K slides along the inclined guide surfaces 1120A and 1120B of the catch hooks 112A and 112B into the lowest region of the connecting gap S between the bearing fingers 111A, 111B and the catch hooks 112A and 112B, the catch hooks 112A and 112B pivot back. As soon as the window pane F has been inserted sufficiently far into the connecting gap S so that the locking lugs 110A and 110B can snap into the connecting openings of the window pane F, the connecting brackets 11A, 11B also pivot back toward the catch hooks 112, 112B.

[0048] The catch hooks 112A and 112B on the base 113A and 113B, which is partially located in the recess OA and OB of the connecting brackets 11A and 11B due to the base sections 114A and 114B, ensure stabilization of the window pane F transversely to the installation direction M during installation. The guide surfaces 1120A and 1120B guide the lower edge K of the window pane F to be installed, once it has already been inserted into the connecting gap S of the pane connecting area 11, into the intended locking position with elastic displacement of the catch hooks 112A and 112B, in which the locking lugs 110A and 110B of each connecting bracket 11A and 11B can snap into the connecting openings of the window pane F. This ensures defined guidance of the window pane F within the connecting gap S up to the locking position. This makes the assembly of the window pane F to the driver 1 easier and less prone to errors.

[0049] For a defined support of the window pane F, which is mounted as intended on the driver 1, support sections in the form of thickened portions 14A and 14B are provided on each base 113A, 113B. Each of these thickened portions 14A and 14B is formed from an elastic soft component injection-molded onto the base 113A or 113B, in such a way that the thickened portion 14A, 14B protrudes at least slightly from the elastic soft component on the base 113A or 113B. The window pane F, which rests locally with its lower edge K on the thickened portions 14A and 14B, is thus connected to the rest of the respective base 113A, 113B via a gap g corresponding to the Figure 2 spaced.

[0050] Compressing the thickened portions 14A and 14B enables a relative displacement of the window pane F to the driver 1 at the pane connection area 11. The thickened portions 14A and 14B provided off-center on the driver 1 can thus ensure a defined support of the window pane F on the driver 1 and, for example, allow an at least slight displacement of the window pane F relative to the driver 1 when the window pane F is retracted into an upper end position. Furthermore, the support on the thickened portions 14A and 14B can achieve rattling relief and consequently avoid switching noise. In particular, the window pane F is supported in a defined manner on the thickened portions 14A and 14B, thus enabling improved pane support of the lower edge K of the window pane F on the driver 1.

[0051] Furthermore, a fluid guide structure 13 is formed on the driver body 10 of the driver 1, via which any fluid, such as penetrating water, can be drained away from the driver body 10 in a defined manner. In particular, the fluid guide structure 13 is designed such that water is directed obliquely toward an edge 10RA, 10RB of the driver body 10 and beyond, specifically such that the water is directed away, in particular, from the traction means 2 and, in particular, from a traction means connection area 12 of the driver 1, where the cable 2 is coupled to the driver 1. The fluid guide structure 13 of the driver 1 is further designed such that any fluid is also directed away from the rail surrounds 10.1 and 10.2 and thus, in the properly assembled state of the window lifter assembly FH, from a guide rail on which the driver 1 is slidably held.

[0052] In the Figures 1A to 6C In the illustrated driver 1, the liquid guide structure 13 comprises several liquid guide elements in the form of drainage channels 130A and 130B; see in particular Figures 6A to 6C . These drainage channels 130A and 130B are provided off-center below a connecting bracket 11A and 11B, respectively. Two drainage channels 130A, 130B run laterally downwards, at least in sections, at an angle to the installation direction M of the window pane F. Each drainage channel 130A, 130B runs on the inner side 1B of the driver 1, thus inclined downwards with respect to the installation direction M of the window pane - as well as an adjustment direction of the driver 1 in the intended installed state - so that, under the effect of gravity, any liquid present on the driver body 10 can flow off laterally via the drainage channels 130A, 130B.

[0053] Each drainage channel 130A, 130B extends beyond a (right or left) edge 10RA, 10RB of the driver body 10, so that the fluid can flow away from the driver body 10 at a projecting end of each drainage channel 130A, 130B. A projecting end of each drainage channel 130A, 130B has an L-shaped cross-section and is open toward the outer side 1A of the driver 1. In this way, fluid drained via the drainage channels 130A, 130B is additionally directed outward and thus, in the properly assembled state of the window lifter assembly FH, away from the other components of the window lifter assembly FH.

[0054] To assist the drainage of liquid via the liquid guide structure 13 having the drainage channels 130A, 130B, the driver 1 can, in the properly assembled state of the window lifter assembly FH, for example, be slightly inclined in the direction of the vehicle interior and in the direction of a vehicle rear in an upper end position which corresponds to a closed position of the window pane.

[0055] For the targeted removal of liquid from the driver body 10, the liquid guide structure 13 can, alternatively or in addition to the drainage channels 130A, 130B, also have liquid guide elements which are formed by ribs and / or depressions on the driver body 10.

[0056] As can be seen particularly in the partially enlarged representation of the Figure 5As can be seen, the driver 1 has a traction means connection area 12 for coupling the driver 1 to the cable pull 2. The traction means connection area 12 arranged centrally on the driver body 10 has two nipple chambers 12.1 and 12.2 which follow one another along a longitudinal direction E1 and into each of which a cable pull end section 20 of the cable pull 1 can be positively inserted in order to transmit an adjusting force for raising or lowering the window pane F to the driver 1.

[0057] For the insertion of a cable pull end section 20 of the cable pull 2, a single assembly opening 120 is provided on the traction means connection area 12, located between the two nipple chambers 12.1 and 12.2. Via the one assembly opening 120, both a cable pull end section 20 along the longitudinal direction E1 into the one (upper) nipple chamber 12.1 and - subsequently - another cable pull end section (in the Figure 5not shown) in an opposite longitudinal or insertion direction E2 into the other (lower) nipple chamber 12.2. A cable pull end section 20 comprises, in a manner known per se, a cable nipple 200 and a spring element supported thereon in the form of a compression spring 201 for cable length compensation.

[0058] When mounting the cable pull 2 ​​via the cable pull end sections 20 to the driver 1, the fundamental difficulty is that the compression spring 201 must regularly be compressed with considerable force to enable insertion into the respective associated nipple chamber 12.1 or 12.2. In contrast, with the driver 1 shown, two cable pull end sections 20 can be inserted one after the other by hand via the mounting opening 120 without any force and, in particular, without compressing the compression springs 201.

[0059] Thus, in the illustrated embodiment, the mounting opening 120 has a length l along the longitudinal direction E1 that corresponds at least to the sum of the lengths b1 and b2 of the adjacent nipple chambers 12.1 and 12.2. Accordingly, a cable nipple 200 with the uncompressed compression spring 201 can be inserted into the mounting opening 120 and then pushed or pulled into the associated nipple chamber 12.1 12.2 along the longitudinal or insertion direction E1 or E2. The space subsequently available via the mounting opening 120 is then sufficient to insert the other cable nipple 200 with its compression spring 201 with the uncompressed compression spring 201 and to push or pull it into the opposite nipple chamber 12.2 or 12.1.

[0060] To facilitate the greasing of a nipple chamber 12.112.2, the traction mechanism connection area 12 has a greasing opening 121.1 or 121.2 on each nipple chamber 12.1, 12.2. This greasing opening 121.1, 121.2 adjoins the central mounting opening 120 (top or bottom) and is provided between the mounting opening 120 and a traction mechanism opening 122.1 or 122.2 of a cable guide channel 12.3, 12.4, through which the cable pull 2, which is connected to the driver 1 as intended, extends away from the respective nipple chamber 12.1 or 12.2. Each lubrication opening 121.1 or 121.2 has a width that is smaller than the width of the central mounting opening 120 in order to hold the cable nipple 200 inserted with the compression spring 201 in the nipple chamber 12.1 or 12.2. At the same time, however, the width of the lubrication opening 121.1 or 121.2 is several times larger than the width of the traction mechanism opening 122.1, 122.2, through which the cable 2 is inserted into the respective cable guide channel 12.3 or 12.4 during assembly. The dimensions of the lubrication opening 121.1 or 121.2 are selected such that the respective nipple chamber 12.1 or 12.2 can be greased from the outside, for example, with a grease block.
