Description

The invention relates to a driver for a motor vehicle window lifter according to the Preamble of claim 1.

Such a driver comprises a connection area for connecting the Driver with the lifting mechanism of a window lifter, especially for Connect the driver with a traction device in the case of a cable window lifter or with a lever arm in the case of an arm window lifter; a recording area for recording of the window pane to be adjusted, so that this is done by means of the provided Lifting mechanism can be raised and lowered; as well as a Adjustment device for adjusting the position of the window pane on the driver.

Due to the adjustability of the position of the window pane on the driver achieve that the window pane after installing the appropriate Window lifters in a vehicle door can be positioned so that they are in their upper End position (corresponding to the maximum lift of the window lifter) with its upper edge defined in the associated window seal of the vehicle, i.e. at closed window on the one hand an adequate sealing of the Vehicle interior opposite the exterior along the top of the Window pane is guaranteed and on the other hand trouble-free retraction and extension the window into the upper window seal is possible.

DE 198 19 953 A1 describes an adjustable driver for connecting a Window to a window of a motor vehicle door known, with which the Position of the upper edge of the window pane - in relation to that installed in a vehicle State of the window regulator - along the horizontal vehicle transverse axis, that is can be adjusted horizontally and perpendicular to the longitudinal direction of the vehicle, namely by Swiveling the window pane by means of an adjustment device provided for this purpose of the driver.

DE 199 56 756 A1 describes an adjustable driver for a window lifter frameless vehicle door known, the one with the lifting mechanism of the Window lifter to be connected first body and one to be adjusted with Has window pane second body (coupling body), the location of the Coupling body is adjustable with respect to the first body in the vehicle longitudinal direction.

The invention is based on the problem of a driver for one Motor vehicle window lifter of the type mentioned further improve.

This problem is solved according to the invention by creating a driver with the Features of claim 1 solved.

Thereafter, the adjusting device as an adjusting gear for adjusting the position of the Window pane on the one hand on a spindle or screw gear, with which the location the window pane is adjustable along a first spatial direction, and one Eccentric, with which the position of the window pane along a second spatial direction is adjustable.

This enables simple adjustment of the position of the window pane along two different, in particular essentially perpendicular to each other standing spatial directions, both adjustment processes by rotary movements of one corresponding setting element (a spindle or screw on the one hand and one Eccentric, on the other hand) about one and the same axis or about mutually parallel Axes can be executed. Because the spindle or screw gear produces an adjustment movement along the axis of rotation and the eccentric an adjustment movement perpendicular to the axis of rotation. This has the advantage that the two setting means, i.e. the Spindle or the screw on the one hand and the one provided with the eccentric Adjustment element on the other hand, when installing the window regulator on a Motor vehicle door can be operated from the same end face of the vehicle door.

The solution according to the invention is also suitable for adjusting the positions of the Window pane in one of two drivers of a double-strand cable window lifter, the other driver of the window lifter so articulated and displaceable is mounted so that it follows the adjustment movement passively.

Related to the state of the window regulator installed in a motor vehicle by means of the spindle or screw gear an adjustment of the position of the Window pane along the vehicle's longitudinal axis and with the eccentric of a setting the position of the window pane along the horizontal vehicle transverse axis (i.e. perpendicular to both the vehicle's longitudinal axis and the vertical vehicle axis) an adjustment of the inclination of the window pane, i.e. by pivoting the Window pane around a swivel axis running parallel to the longitudinal axis of the vehicle.

According to one variant of the invention, the setting device is designed for one independent adjustment of the position of the window pane along the two Spatial directions so that when adjusting the position of the window pane along the one spatial direction the position of the window pane along the other spatial direction remains constant. For this purpose, the spindle or screw gear are on the one hand and the eccentric, on the other hand, can be operated independently of one another.

According to another variant of the invention, the two adjustment gears are coupled with each other so that an adjustment of the position of the window pane along the one spatial direction also to a change in the position of the window pane leads along the other direction. The two adjustment gears are included preferably summarized in such a way that the position of the window pane initially is adjustable along a first spatial direction, in particular along the Vehicle longitudinal axis, and then its position along the second spatial direction, in particular the horizontal vehicle transverse axis, is set, the position of the Window pane along the first spatial direction is only negligible will be changed.

This can be achieved in that the eccentric has an external thread that cooperates with a nut to form a spindle or screw gear. Then by rotating the eccentric in the nut in the manner of a spindle or Screw gear first the position of the window pane along the Longitudinal vehicle axis set. Finally, a maximum of half a turn of the Eccentric required to adjust its position by adjusting the inclination of the window pane adjust along the horizontal vehicle transverse axis, with only one slight, negligible change in the position of the window pane along the Longitudinal vehicle axis comes. This is given by the slope of the Eccentric screw thread. By using an external thread with a the final change in the position of the Minimize window pane in vehicle longitudinal direction; at the same time means one small pitch of the screw thread that a correspondingly larger number of Rotations of the eccentric is required to adjust the position of the Cover a defined distance along the vehicle's longitudinal axis can.

According to one embodiment of the invention, this is at least one Setting device for the position of the window pane on the driver Adjusting gear designed self-locking to a previously set position Fix window pane.

According to another embodiment, additional means for locking the Window pane provided after completing an adjustment movement, for example one Lock nut or positive locking areas. The adjustment gear can be by means of a Spring to be resiliently biased towards the locked state so that it before performing an adjustment movement, first against the bias from the locked state must be brought into an unlocked state.

The position of the window pane is preferably set in such a way that the spindle or screw gear and the eccentric on a swivel and adjusting part mounted longitudinally displaceably on a base body of the driver act on which the window pane is attached. The attachment can in particular by means of a clamping screw, the mutually assigned openings in the Adjustment part, in the window pane and in a jaw of the driver reaches through, so that the window pane between the adjustment part and the other Jaw is clamped. This is the setting of the position Window pane by means of the spindle or screw gear and by means of the Eccentric regardless of the attachment of the window on the driver. The means that the window pane must be fastened to adjust its position on the Carriers are not loosened. The reverse is true after disconnecting the connection a previously set window position does not exist between the window window and the driver lost, but is used for a later reinstallation of the window pane in the Carrier preserved.

In addition, the driver can also adjust the position of the window pane along a third spatial direction, namely that which is vertical when installed Allow vehicle axle, e.g. by the the area for the window pane carrying base body of the driver slidably on a connecting area of the Driver is arranged to connect the driver with the Window lifter lifting mechanism.

Further features and advantages of the invention will become apparent in the following Description of exemplary embodiments will be apparent from the figures.

In Figures 1, 2a and 2b is a driver for a motor vehicle window regulator shown, the a receiving area 1 for a window pane to be adjusted as well a connecting section 2 with a nipple chamber 20 for producing a Has connection with the drive cable of a motor vehicle window lifter.

The receiving area 1 is formed by a base body 10 of the driver and an associated clamping jaw 11, which counteracts such by means of a clamping screw 12 the base body 10 can be clamped so that one of a disc holder 7 in Area of their lower edge encompassed window pane between the base body 10 and the clamping jaw 11 can be clamped, the clamping screw 12 passes through a pane opening provided for this purpose and the clamping jaw 11 together with the disk holder 7 from one of the base body 10 protruding elastic hook 14 is encompassed. Such carriers are general known, so that the details of the disc attachment are not explained here.

Two bearing sections 16, 18 stand laterally from the base body 10 of the driver each have an opening 17 and 19 for receiving the shaft 31 a Have adjusting screw 3. The two bearing sections 16, 18 are along the Longitudinal axis L of the shaft 31 of the adjusting screw 3 spaced apart and thus enable the setting of the connecting section 2 with the nipple chamber 20 along that direction. For this purpose, the connecting section 2 is between the two Bearing sections 16, 18 arranged on the shaft 31 of the adjusting screw 3, namely by means of a section 21 provided with an internal thread.

To operate the adjusting screw 3 is provided with an external toothing Actuating section 30, in the form of a screw head designed as a gear provided, which also with a gear with an external toothing 40th trained drive element 4 is engaged. The drive element 4 is a Pin 45 rotatable in another protruding from the base body 10 Bearing section 15 of the driver mounted and has an inner polygon 42, the an actuation of the drive element 4 allows with a suitable tool. The The axis of rotation D of the drive element 4 runs parallel to the longitudinal axis L of the Adjustment screw 3.

If the drive element 4 is actuated by actuating its inner polygon 42 with a Tool rotated, this rotary movement is via the external toothing 40 of the Transfer drive element 4 to the actuating head 30 of the adjusting screw 3, see above that a corresponding rotary movement of the adjusting screw 3 is triggered. The Shank 31 of the adjusting screw 3 has a thread on the type on which longitudinally displaceable and rotationally fixed, the section 21 of the nut Connection section 2 of the driver is mounted. A rotary movement of the Adjustment screw 3 thus causes a movement of the nipple chamber 20 of the Connecting section 2 in one direction or the other along the longitudinal axis L. the adjusting screw 3, depending on the direction of rotation of the adjusting screw 3.

The maximum possible adjustment of the nipple chamber 20 is due to the distance of the two bearing sections 16, 18 of the base body 10 along the longitudinal axis L of the Set screw 3 limited. To fix a certain position of the nipple chamber 20 between the two bearing sections 16, 18 is a lock nut 35, which on the the actuating head 30 facing away from the end 32 of the threaded shaft 31 Adjusting screw 3 is screwable. The lock nut 35 can optionally on one Outside polygon 36 or an inner polygon 37 with a suitable tool be operable.

On the basis of Figures 1, 2a and 2b, it is particularly clear that both the Drive element 4 and the lock nut 35 each in the manner with associated tool intended for their actuation can be brought into engagement that this tool against the direction r along which the threaded shaft 31 of the Actuating head 30 of the adjusting screw 3 protrudes to the corresponding Engagement area 42 or 36 or 37 is guided.

The direction r along which the longitudinal axis L of the adjusting screw 3 extends and along which the nipple chamber 20 is adjustable by means of the adjusting screw 3 essentially the vertical vehicle axis z (see FIG. 4) or points at least a substantial component in the direction of the vertical vehicle axis z on, so that the arrangement shown in Figures 1, 2a and 2b in particular a Setting the nipple chamber 20 of the driver with respect to the base body 10 of the Driver allowed along the vertical vehicle axis. The one to carry out this Adjustment or required to fix a previously performed setting Elements, namely the drive element 4 and the cooperating with it Adjustment screw 3 and the lock nut 35 can each by a from above to the driver guided tool can be operated, which for this purpose with the Inner polygon 42 of the drive element 4 or the outer or inner polygon 36 or 37 of the lock nut 35 is engaged.

Based on an overview of Figures 1, 2a and 2b with Figures 3a and 3b clearly that the driver has another setting option, namely the Possibility of pivoting those picked up by the driver Window pane together with that encompassing the lower edge of the window pane Disc holder 7 by means of an adjustment part 6 provided for this purpose.

The adjustment part 6 is pivotably articulated on the base body 10 of the driver, wherein the pivot axis is formed by a pin 600, the one hand openings 100 in the base body 10 and on the other hand an opening 60 of the adjusting part 6 be upheld. The adjustment part 6 extends between the base body 10 and the Disc holder 7 of the driver, so that when the Adjustment part 6 about its swivel axis 600 together with the disc holder 7 the adjustment part 6 with respect to the base body 10 is pivoted and the position the window pane (more precisely the position of the extension plane of the Window pane) changes with respect to the base body 10 of the driver.

To actuate the adjustment part 6, which is flat between the base body 10 and the disc holder 7 of the driver extends is an elongated Adjustment element 5 is provided, one in the axial direction one behind the other Outer polygon 58 forming section, a section forming an eccentric 50 and has a section forming an external thread 55. The the external thread 55 forming section is in a corresponding internal thread 65 of the adjusting part 6 insertable and the eccentric 50 acts with the long sides 13L in the base body 10 provided slot 13 together. This happens in the way that Actuation of the outer polygon 58 with an associated tool Adjustment element 5 with its section provided with an external thread 55 in the assigned threaded bore 65 of the adjusting part 6 screwed in or out of this can be turned out, the eccentric 50 with its outer eccentric surface acts on the long sides 13L of the elongated hole 13 in the base body 10 and thereby each according to the angular position of the adjusting element 5 and thus also of the eccentric 50 Defined deflection of the adjustment part 6 with respect to the base body 10 around the Swivel axis 600 defined. Here, the directly on the flat adjustment part 6 adjacent disc holder 7 taken, so that a setting the position of the window pane accommodated in the pane receptacle 7, and by pivoting about an axis 600, which in the installed state of the Window lifter runs along the vehicle's longitudinal axis x. Based on the geometry of the driver, the direction of the pivot axis 600 as parallel to Lower pane edge of a window pane picked up by the driver be defined on an ongoing basis. A pivoting movement of the disc holder 7 and thus the window pane picked up by the driver about this pivot axis 600 corresponds to a displacement of the upper edge of the at small swivel angles Window pane perpendicular to the plane of the pane, i.e. perpendicular to the vehicle's longitudinal axis and perpendicular to the vertical vehicle axis.

The longitudinal extent of the elongated hole 13 is chosen such that the two End faces 13s of the elongated hole 13 are spaced apart from one another to such an extent that the Eccentric 50 in no rotational position with its outer eccentric surface with one of these End faces 13s in operative connection. This prevents the eccentric 50 a relative movement between the base body 10 and the adjustment part 6 perpendicular to the pivot axis 600 in the direction r (see FIG. 1), along which the position of the base body 10 with respect to the nipple chamber 2 is adjustable.

A special feature of the driver shown in Figures 1 to 3b is in that the displacement of the upper edge of the window pane by means of the Adjustment element 5 and the adjusting part 6 generated pivoting movement of one Tool can be triggered, which along the pivot axis 600 (and thus based on the state of the driver installed in a motor vehicle along the Longitudinal vehicle axis x) with the outer polygon 58 of the adjusting element 5 in engagement can be brought to twist it about its longitudinal axis. This enables in particular an adjustment of the position of the upper edge of the pane perpendicular to Extension plane of the window from the front of a vehicle door, such as will be described below with reference to Figure 4.

Is the setting of the position of the window by means of the setting element 5 and Adjustment part 6 completed, the current position of the setting element 5 and thus in particular the eccentric 50 fixed by means of a lock nut 59 which on the outside polygonal end of the adjusting element 5 can be screwed.

It can also be seen from FIGS. 3a and 3b that the clamping screw 12, by means of which the window pane can be clamped in the receiving area 1 of the driver, aligned disc openings 10a, 6a, 7a and 11a in the base body 1, passes through the adjusting part 6, the disk holder 7 and the clamping jaw 11, a corresponding opening also being provided in the window pane itself is.

Figures 1 a and 1b show a possibility in the one shown in Figure 1 Driver the nipple chamber 20 of the adjustable by an adjusting screw 3 Connection section 2 by a connection section 2 'with a not adjustable nipple chamber 20 'to replace. The connecting section 2 'with the adjustable nipple chamber 20 'instead of one designed as a nut Section for receiving the threaded section of the adjusting screw 3 two Lugs 27 ', 29', which actually hold the adjusting screw 3 provided through openings 17, 19 of the bearing sections 16, 18 of the Recording area 1 of the driver can be inserted. This can help those drivers where the position of the window pane can be adjusted the vertical vehicle axis is not required, in a cost-effective manner adjustable connecting section 2 by a non-adjustable connecting section 2 'can be replaced without any at the receiving area 1 of the driver Modifications would be required. Rather, the adjusting screw 3 and saved the drive element 4, by means of which the adjustable nipple chamber 20 ' was movable along its direction of adjustment and one by two locking lugs 27 ', 29' non-adjustable connecting section 2 'replaced with a nipple chamber 20'.

FIG. 4 shows a motor vehicle door consisting of an outer door skin A, one Inner door skin I, one on a large section of the inner door skin I attached door module carrier T, on which different functional components of a Motor vehicle door, such as. B. a window regulator, a door lock, a speaker system and a side airbag module can be preassembled, as well as a door interior paneling V.

The height of the door is adjustable by means of a conventional cable window lifter Window F on which a driver M of the in Figures 1 to 2b shown type with the drive mechanism (drive cable) of the cable window lifter is connected and through a door shaft S in the vicinity of it Undershot U in the area between the outer skin A and the inner skin I is led. There, the window pane F is received by the driver M.

The window lifter shown in FIG. 4 can in particular be a Act so-called double-stranded window lifter, which by means of a drive cable Form of a closed rope loop two along the vehicle's longitudinal axis (vertical to the yz-plane shown in FIG. 4) drives drivers spaced apart from one another, each a section of the window pane in the area of the lower edge of the pane embrace and absorb. In Figure 4 of these two along the Vehicle longitudinal axis, that is arranged one behind the other perpendicular to the image plane Only the front driver M can be seen. In the case of a driver's door, one Motor vehicle, this is the B-pillar-side driver M, that is the driver located adjacent to the B-pillar of the vehicle, during the other driver located further ahead, adjacent to the A-pillar, is hidden.

To simplify the arrangement, a double-strand cable window lifter only one of the two drivers, in this case the one on the B-pillar side that can be seen in FIG Driver M, with an adjustment mechanism of the in Figures 1, 2a and 2b shown type, while the other driver is only passive understand the respective setting of the window pane, in such a way that the lower edge of the pane is defined along the horizontal (Vehicle longitudinal direction) runs.

The door shaft S is delimited on the side of the outer door skin A by a Shaft reinforcement SV and on the side of the inner door skin I through a door parapet B, on which the inner door panel V is attached. The door shaft S thus forms in the upper area of the formed by the outer door skin A and the inner door skin I. Door body an opening through which the window pane F from above led in sections into the area between outer door skin A and inner door skin I. can be.

Is the window pane F by means of the associated, not shown in Figure 4 Window lifter lowered into its lowest pane position, so there is almost that entire window pane in the area between outer door skin A and inner door skin I; only the upper pane edge O then still protrudes through the door shaft S. upwards. In contrast, the window pane F is by means of the window lifter move to its uppermost position, it protrudes almost completely from the door shaft S out; only that part of the window pane F which is accommodated in the driver The area around the lower edge U is still in the area between Outer door skin A and inner door skin I.

In the uppermost pane position, which can be reached using the window regulator can, it must be ensured that the window pane F with its upper edge O completely included in a section of the window seal provided for this purpose is. This is the only way to ensure that the window pane is in its upper pane position moisture and watertight sealing of the vehicle interior to the outside out. In order to meet this requirement, the driver M according to FIGS. 2a and 2b provided that the connecting section 2 over which the driver is connected to the drive mechanism (drive cable) of the window lifter, along the vertical vehicle axis z relative to the receiving area 1 of the driver M. can move, which serves to accommodate the window pane F to be adjusted. How already explained with reference to Figures 1, 2a and 2b, must first for this setting by means of a suitable tool with the adjusting screw 3 in operative connection standing gear element 4 are operated. Then the previously set position of the adjusting screw 3 by actuating this provided lock nut 35.

The adjusting screw 3, the drive element 4 and the lock nut 35 are in Figure 4 in Area of the driver M each shown schematically and with the reference symbol E. (for the adjusting screw), G (for the drive element) and K (for the lock nut) Mistake.

It is clear from FIG. 4 that both the drive element G and the Lock nut K can each be operated by means of a tool W that above along the vertical vehicle axis z through the door shaft S to the corresponding element G or K is guided and engaged with it. The For this purpose, door shaft S must have such a width in the area of the door sill B that the tool W next to the window pane F through the shaft S in the area between outer door skin A and inner door skin I can be performed.

Figure 4 shows an assembly step in which a tool W from above through the Door shaft S protrudes into the area between outer door skin A and inner door skin I. and with an inner polygon grips the outer polygon of the lock nut K to this to operate, that is, a position of the previously set by means of the adjusting screw E. Fix nipple chamber 20 (see Figures 1 to 2b). Alternatively, you could a tool provided with an external polygon can be used when on the Lock nut K a corresponding inner polygon is provided.

In the same way, a suitable tool W (preferably under Use the same tool W as for the lock nut K) das Actuate drive element G to rotate the drive element G to trigger coupled adjusting screw E, which in turn leads to readjustment of the Position of the nipple chamber 20 (see Figures 1 to 2b) with respect to the base body 10 of the driver leads.

The arrangement shown in Figure 4 has the essential advantage that both the Actuation of the adjusting screw E serving drive element G as well as for Fixing the adjusting screw in a specific position lock nut K in each case from above through the door shaft S, that is along the same direction from a tool W can be grasped and that this is with the window pane F raised can be done so that it can be immediately determined whether the current position of the Nipple chamber to the desired position of the upper pane edge O in the assigned Section of the washer seal leads.

This is made possible by the tool W for actuating the Adjusting screw E is not located on the opposite of lock nut K Actuating section 30 (see Figures 1 to 2b) of the adjusting screw. Because this could not be grasped from above using a tool, since the Lock nut K and the shaft of the adjusting screw E give access to the Block the operating section from above. Instead, the Adjusting screw E via the separate drive element G, which is vertical in one plane to the vertical vehicle axis z or to the longitudinal axis of the adjusting screw E next to the Actuating section of the adjusting screw E is arranged and its axis of rotation runs outside (next to) the longitudinal axis of the adjusting screw E. This can Tool W for gripping the drive element G on the threaded shaft of the Adjustment screw E is passed and extends next to this if it is Grips drive element G for actuating the adjusting screw E.

In Figure 4, the further adjustment element EE with his External polygon AMK shown, which in Figures 3a and 3b as an adjusting element 5th is designated with external polygon 58 and which serves the upper edge O of Window pane F by pivoting along the horizontal vehicle transverse axis y to move so that the upper edge of the window seals when the window is closed on an assigned window seal of the vehicle door or roof frame (in Case of a frameless vehicle door).

It is important here that the outer polygon AMK further Adjusting element EE from one end of the vehicle door along the Longitudinal vehicle axis x can be gripped by means of a tool and then by twisting the tool and thus also the setting element EE the desired one Trigger pivoting movement of the window pane F and the upper pane edge O to be adjusted along the horizontal vehicle transverse axis y. (In the case of Figure 4 The vehicle door shown is a driver's door, so that the illustration in FIG. 4 corresponds to a direction of view from the B-pillar onto the vehicle door.)

As a result, this means that the position of the window pane F in the position shown in FIG Driver M shown along the vertical vehicle axis z and along the horizontal vehicle transverse axis y can be adjusted using tools that through the door shaft S or through a suitable opening in one end face through the vehicle door with the respectively assigned adjusting means E or EE in Intervention. This can be done in a state where the Window pane F by means of the assigned window lifter in its upper Window position has been brought so that the top edge O of the window pane F is in the area of the associated washer seal and setting the position the upper edge O of the window pane F along the vertical vehicle axis z and made along the horizontal vehicle transverse axis y directly in the manner can be that the desired position of the upper edge O of the window pane F in the Washer seal is adjusted. This leads to a considerable simplification of the Adjustment of the driver M of the window lifter, as a multiple lifting and There is no need to lower the driver during assembly.

The drive element 4 with the inner polygon 42 (see Figures 1, 2a and 2b) to be stored on the carrier in this way (by appropriate spatial arrangement of the Bearing section 15 of the driver) that the inner polygon 42 is not by the in Driver window pane is covered but also at recorded window pane is freely accessible for a tool. There is one such arrangement of the bearing section 15 and thus also the inner polygon 42 of the drive element 4 stored therein, in which the in the driver recorded window pane F (see Figure 4) as a guide for the tool can serve, for example in such a way that a along a disc surface or Tool edge moving tool essentially in vertical direction (z-direction) with its engagement area in engagement with the inner polygon 42 of the Drive element 4 device.

It can also be seen from FIGS. 3a and 3b that by screwing in the with the eccentric 50 adjusting element 5 with its external thread 55 in the associated threaded bore 65 of the adjusting part 6 is a displacement of the Adjustment part 6 along the direction of extension of the adjusting element 5, that is along the vehicle longitudinal axis x (based on the installed state of a appropriate window regulator) could be generated. By putting the window pane over the fastening screw 12, the through hole 6a of the adjusting part 6 and one corresponding disk opening is firmly connected to the adjusting part 6, the Window pane when the adjusting part 6 moves in the vehicle longitudinal direction x (compare Figure 4), so that here an additional degree of freedom in the Adjustment options of the window pane would be provided.

As a result, the position of the window pane in the driver could then be determined using the adjustable nipple chamber 20 in the vertical direction (i.e. along the vertical Vehicle axis), by pivoting about the pivot axis 600 provided for this purpose by means of the eccentric 50 along the horizontal vehicle transverse direction and by means of the Thread section 55 of the adjusting element 5 finally along the Adjust vehicle longitudinal axis. This corresponds to an adjustability along three mutually perpendicular spatial directions, namely the vehicle longitudinal axis x, the horizontal vehicle transverse direction y and vertical vehicle axis z, see figure 4), so that a full adjustability of the position of the window pane in Carrier is guaranteed.

It should be noted here that the through openings 7a, 10a of the pane holder 7 and the base body 10 have a considerably larger diameter than that Clamping screw 12. This allows the clamping screw 12 to be relative to the Base body 10 and the disc holder 7 along the longitudinal axis of the Move adjustment element 5. As a result, the position of the Window pane along the longitudinal axis of the adjusting element 5 required Mobility of the adjustment part 6 and the window pane relative to the base body 10 of the driver allows.

This third adjustment option is described below with reference to that in FIGS. 7a to 9d illustrated embodiment of a driver are explained in more detail.

• Für die Veränderungen der Lage der Fensterscheibe in horizontaler Richtung, einerseits entlang der Fahrzeuglängsachse und andererseits quer zur Fahrzeuglängsachse, ist eine Verschwenkbarkeit (bezüglich der hierfür vorgesehenen Schwenkachse 600) sowie eine Verschiebbarkeit (entlang der Längsachse des Einstellelementes 5) des Verstellteiles 6 relativ zu dem Grundkörper 10 des Aufnahmebereiches 1 des Mitnehmers erforderlich. Die Größe der Durchgangsöffnung 10a im Grundkörper 10 des Aufnahmebereiches 1 des Mitnehmers ist dabei - verglichen mit dem Außendurchmesser der Klemmschraube 12 - so gewählt, dass die Klemmschraube 12 die beiden vorgenannten Verstellbewegungen, nämlich ein (geringfügiges) Verschwenken des Verstellteiles 6 relativ zu dem Grundkörper 10 um die Schwenkachse 600 sowie gegebenenfalls ein Verschieben des Verstellteiles 6 relativ zu dem Grundkörper 10 entlang der Längsachse des Einstellelementes 5 nicht behindert.

It is also important that the adjustability along all axes is possible in the case of the driver shown in FIGS. 1 to 3b, without the pane fastening having to be released by means of the clamping screw 12;

• The adjustment along the vertical direction is carried out by relative movement of the entire receiving area 1 of the window pane together with the base body 10 relative to the nipple chamber 20. Since the window pane is only taken up by the receiving area 1, no loosening of the pane attachment is necessary in order to relative to the receiving area 1 to move the nipple chamber 20, via which the driver is attached to the lifting mechanism of the window regulator.
• For the changes in the position of the window pane in the horizontal direction, on the one hand along the longitudinal axis of the vehicle and on the other hand transversely to the longitudinal axis of the vehicle, there is a pivotability (with respect to the pivot axis 600 provided for this purpose) and a displaceability (along the longitudinal axis of the adjusting element 5) of the adjusting part 6 relative to the base body 10 of the receiving area 1 of the driver is required. The size of the through-opening 10a in the base body 10 of the receiving area 1 of the driver is - compared to the outside diameter of the clamping screw 12 - chosen so that the clamping screw 12 does the two aforementioned adjustment movements, namely a (slight) pivoting of the adjustment part 6 relative to the base body 10 around the pivot axis 600 and, if appropriate, a displacement of the adjustment part 6 relative to the base body 10 along the longitudinal axis of the setting element 5 is not impeded.

As a result, the position of the window pane on the driver is adjusted on the one hand and the fastening of the window pane to the driver on the other hand independent assemblies and without one process the other affected. In other words, to change the position of the window pane on the driver, the The pane attachment cannot be loosened and vice versa, loosening the Disk fastening by means of the clamping screw 12 is not the previously selected setting the position of the window pane, which results from the relative position of the recording area 1 and connecting section 2 of the driver and from the relative position of the Adjustment part 6 results in relation to the base body 10 of the driver.

The driver shown in Figures 5a to 5d and 6a and 6b differs of the one described with reference to FIGS. 1 a to 3 b in the training and Storage of the adjusting element 5 'provided with an eccentric 50', with which the Adjustment part 6 with respect to the base body 10 of the receiving area 1 of the driver is pivotable.

The elongated adjusting element 5 'having the eccentric 50' in the form of a a bearing shaft eccentric 50 'is in a bearing section 105 of Base body 10 of the driver mounted and by means of a collar 59 'on the longitudinally extending adjusting element 5 'acting leaf spring 150 so elastic biased that two each formed as a tapering polygon (octagon) Form-locking elements 56 'of the setting element 5' without play in assigned, themselves tapered positive locking areas 106 of the bearing area 105 of the base body 10 are pressed. As a result, the adjusting element is against a rotational movement about its Longitudinal axis secured; so it is locked.

To activate the eccentric 50 ', the corresponding setting element 5' must be on it provided for this purpose, also designed as a polygonal actuating head 58 ' gripped with a suitable tool and against the action of the leaf spring 150 are displaced such that the positive locking elements 56 'of the longitudinally extended Adjustment element 5 'out of engagement with the associated positive locking areas 106 of the Storage area 105 of the base body 10. Then the setting element 5 ' by means of the tool gripping the actuating head 58 'about its longitudinal axis turn, the eccentric 50 'triggers a pivoting movement of the adjusting part 6. The Eccentric area 50 'of the elongated adjusting element 5' is for this purpose via a Tolerance compensation serving guide clip 67 in a U-shaped receptacle 66 of Adjustment part 6 arranged.

After turning the adjusting element 5 'to the point at which the Eccentric 50 'the desired inclination of the adjusting part 6 and thus the window pane has been set, the setting element is automatically locked again 5 'under the action of the leaf spring 150 as soon as there is no more pressure on the adjusting element 50 'is exercised against the action of the leaf spring 150. The positive locking elements 56 'of the setting element 5' then automatically return to the assigned one Form-locking areas 106 of the base body 10.

Due to the design of the form-locking elements 56 'each made possible as a polygon this embodiment only a step setting of the inclination of the adjusting part 6 and thus the window pane, the fineness by the number of edges of the two polygon 56 'is given.

To adjust the position of the window pane along the vehicle's longitudinal axis, corresponding to a displacement of the adjustment part connected to the window pane 6 along the direction of extension of the adjusting element 5 'is a screw gear 8, the one with an externally threaded adjusting screw 80 and a non-rotatable in a housing area provided with through openings 62 for the screw 80 61 of the adjusting part 6 has mounted nut 81. By rotating the Adjusting screw 80, which for this purpose has an actuating section 88 at an axial end can be gripped by means of a tool provided for this purpose Longitudinal movement of the adjustment part 6 along the longitudinal axis of the adjusting screw 80 can be generated relative to the base body 10 of the driver. The adjusting screw 80, the through openings 100 of the base body 10, each associated with their ends reaches through, serves at the same time as an axis of rotation for the means of the eccentric 5 ' generated pivoting movement of the adjustment part 6, see Figure 6c.

The adjustment movement described is between appropriate spaces FR between enables the base body 1 and the adjustment part 6 along the adjustment direction, compare Figure 5b.

It is also clear from FIGS. 5a to 6c that the eccentric 50 ' having longitudinal extension element 5 'and the adjusting screw 80 in parallel extend to each other and each have an actuating section 58 'at one end, 88 for actuation by a tool. The respective operating section 58 ', 88 is in the installed state of the driver as part of a window regulator an end face of a vehicle door, in particular the B pillar end face in the case a driver or passenger door, so that the actuation of the elongated Adjusting element 5 'and the adjusting screw 80 by means of a tool each have an opening in the corresponding end face of the vehicle door can, see also Figure 4. The through holes in the corresponding end face the vehicle door are to be arranged so that they have access to the setting element 5 'and the adjusting screw 80 at maximum disc stroke, d. H. at by means of allow the corresponding window lifter to lift the maximum of the window pane. This enables the advantages described with reference to FIG Formation of the mechanism for adjusting the position of the window on Make optimal use of drivers along the vertical vehicle axis.

In total, there are three in the driver shown with reference to Figures 5a to 6c separate, independently operable and independently acting Assemblies for adjusting the position of the window pane along the three Space axes provided, namely an adjustment of the base body 10 of the Driver relative to the nipple chamber 20 for an adjustment of the position of the Window pane on the driver along the vertical vehicle axis Screw gear 8 for adjusting the position of the window on the driver along the vehicle's longitudinal axis as well as an elongated adjusting element 5 ' Eccentric 50 'for pivoting the window pane about the longitudinal axis of the vehicle, corresponding to a movement of the upper edge of the window pane along the horizontal vehicle transverse axis. The screw gear and the eccentric gear each act on an adjustment part 6 which is firmly connected to the window pane.

Finally, it is important that - as already with reference to Figures 1 to 3b executed - the clamping screw 12 ', by means of which the window pane between the Adjustment part 6 and the holding plate 11 is clamped, completely independently of the individual adjustment devices for adjusting the position of the window pane acts. That is, the setting of the position of the window pane is 12 'when the clamping screw is tightened possible and loosening the clamping screw 12 'does not change the previously set Position of the adjustment part 6 on the driver. This means that a window pane can be closed Removed for repair purposes and replaced by another window pane, the latter then the one previously set using the other window pane Disc position takes over.

In the figures 7a, 7b and 8a, 8b, a driver is shown, in which the difference a single to the driver described with reference to Figures 5a to 6c Adjustment element 9 both for pivoting the adjustment part 6 with respect to the Base body 10 of the driver as well as for a longitudinal displacement of the adjustment part 6 is provided and designed with respect to the base body 10. In the present The two functions are therefore the embodiment of the setting element 9 taken over in the driver shown with reference to Figures 5a to 6c on the one hand by the adjusting element 5 and 5 provided with an eccentric 15 on the other hand were realized by the adjusting screw 8. This summary of the two adjustment options mentioned was already described in the description of the driver shown in Figures 1 to 3b.

The eccentric 90 formed on a shaft 96 of the adjusting element 9 is present (see also Figure 9a) provided with an external thread with which it fits into a Threaded bore 69 of a projection 68 of the adjusting part 6 can be screwed in. On the other hand, the eccentric is mounted in a bearing section 105 of the base body 10 and fixable there in a defined position by means of a lock nut 99, which on a Threaded portion 95 of the eccentric shaft 91 can be screwed on.

At its end facing away from the bearing section 105 for the adjusting element 9 the base body 10 bearing holes 100, in which a pin 600 to form a Pivot axis is inserted, on which the adjusting part 6 by means of a Through opening 64 provided projection 63 pivotable and at the same time in Longitudinal direction of the pin 600 is slidably mounted, the slidability of the Adjustment part 6 with respect to the base body 10 through corresponding free spaces FR is made possible.

To adjust the position of the adjustment part 6 with respect to the base body 10 (and thus the window pane in the pane holder 1), the adjusting element 9 with a suitable tool on its actuating section 98 which is designed as a polygon gripped, this access along the direction of extension of the adjusting element 9 (corresponding to the longitudinal axis of the vehicle when the window lifter is installed done) and then rotated. By the interaction of the external thread of the Eccentric 90 comes with the internal thread of the threaded bore 69 of the adjusting part 6 this leads to a relative movement of the adjustment part 6 with respect to the base body 10 of the driver in the direction of extension of the adjusting element 9, i.e. along the Longitudinal vehicle axis x. Because of the eccentricity of the with the external thread provided eccentric section 90 of the adjusting element 9 changes here continuously the inclination of the adjusting part 6 with respect to the base body 10. This However, the inclination is initially irrelevant until the correct position of the adjustment part 6 with respect to the base body 10 in the direction of extension of the adjusting element, i.e. in Longitudinal vehicle direction has been set.

Subsequently, the setting element 9 is again slightly rotated further until the eccentric 90 is in a pivoted position which the corresponds to the desired inclination of the adjustment part 6 with respect to the base body 10. This subsequent adjustment of the inclination of the adjustment part 6 after its adjustment in the longitudinal direction leads to another, slight change in the position of the adjustment part 6 with respect to the base body 10 in the longitudinal direction (Direction of extension of the adjusting part 9); however, this correction is so slight that it can be easily accepted. Because after hiring the Position of the adjustment part 6 with respect to the base body 10 of the driver 1 in The eccentric 90 (and thus the adjusting element 9 as a whole) must still be in the longitudinal direction a maximum of half a turn until the desired inclination of the Adjustment part 6 is set with respect to the base body 10. With one accordingly The slight slope of the external thread of the eccentric 90 is the associated one Change in the position of the adjustment part 6 in the longitudinal direction is irrelevant. The end position the adjusting part 6 with respect to the base body 10 of the driver is then by means of a lock nut 99 secured to a corresponding threaded portion 95 of the Adjusting element 9 is screwed.

In the present case, the adjusting element 9 and the adjusting part 6 form a unit a single actuating section 98 actuatable adjustment gear for both Adjustment of the inclination of the window pane in the driver as well as for its adjustment in the longitudinal direction of the vehicle. The position of the window pane is set in Longitudinal direction of the vehicle before setting the window inclination. Regardless of this the setting of the position of the window pane in the driver along the vertical Vehicle axis, which is caused by an adjustment of the position of the nipple chamber 2 of the base body 1 of the driver.

The driver shown in Figures 7a to 8b has with respect to the setting of the Location of the window pane has the advantage that a through opening in one end a vehicle door is sufficient to adjust the Position of the window in the driver both along the vehicle's longitudinal axis and also along the horizontal transverse vehicle axis running perpendicular to this make.

FIGS. 9a to 9d show an assembly concept for assembling the base body 10 shown with the adjusting part 6 and the adjusting element 9. It will be with the Eccentric 90 provided adjustment element 9 (see Figure 9a) first with the Eccentric 90 in the threaded bore of the corresponding projection 68 of the Adjustment part 6 screwed in, see Figure 9b. Then, according to FIGS. 9c and 9d the adjustment part 6 is connected to the base body 10 of the driver, the Adjustment element 9 is inserted into the bearing area 105 of the base body 10. it then the pivot axis between the base body 10 and Adjusting part 6-forming pin 600 (see Figures 8a and 8b) in the for this provided openings 64, 100 of the adjustment part 6 on the one hand and the base body 10 on the other hand are inserted.
