Abstract

The window lifter assembly has functional components, which are arranged at a carrier (1) before proper arrangement in a vehicle in a preassembly position. The distance between the functional components is smaller during arrangement of the functional components in their functional position in a motor vehicle for a part of the possible function component-pairs.

Description

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

A Such window regulator assembly comprises a carrier; one flexible traction means for transmitting one of a drive the window generated drive torque to one by means of the window regulator window pane to be adjusted; and arranged on the carrier Functional components of the window lift, each on the flexible Attack pulling means. For example, among these functional components be a so-called rope drum, by the flexible traction means is entwined and operated by the power window drive (is rotated) to a drive side generated drive torque in to initiate the flexible traction device. Furthermore, it can be at least one of the functional components around a deflecting element of the window regulator act, which serves to redirect the flexible traction means so that - according to the order the functional components on a motor vehicle - at least one Section of the traction device along a direction extending along to be moved to be adjusted window pane. After all can at least one driver among the functional components be, on the one hand connected to the flexible traction means and on the other hand connected to the window pane to be adjusted is so that over that driver one (through the window regulator drive triggered) adjusting movement of the flexible traction means in a corresponding movement of the window pane to be adjusted is implemented.

These Functional components are as intended Arrangement in a motor vehicle in each case a functional position positioned on the motor vehicle and thereby take defined layers one another, so that the flexible traction means along a predetermined Track is guided, which is an adjustment of the adjusting Window pane along a specific, predetermined adjustment path allows.

So is in a motor vehicle to be adjusted window pane to release and close a window opening of the motor vehicle regularly along an adjustment path moving, which deals with a substantial component along the vertical vehicle axle (which from the vehicle floor in the direction of the vehicle roof points), but beyond also additional components along other spatial directions may have, for example, one of the shape of the Vehicle body adapted curved adjustment results. In such a case, the flexible traction device according to regulations Installation in a motor vehicle to lead such that at least a portion of the flexible traction means with a substantial Component extends along the vertical vehicle axis, so that by connection of the window to be adjusted to those Zugmittelabschnitt (For example, via a so-called driver) a longitudinal movement of the flexible traction means in an adjusting movement of the window to be adjusted along its adjustment path can be implemented.

Farther the flexible traction device must be guided so that another Section of the traction means, for example via a cable drum, is in operative connection with the window regulator, so that an am Power window drive generated drive torque in the flexible traction device is initiated and this performs a motion at the guided along the adjustment of the window to be adjusted Zugmittelabschnitt moves along that adjustment and here (via a driver) the window to be adjusted - ever according to drive direction - to release or close a Window opening takes along.

It is known to pre-assemble a window lifter or at least part of the functional components of a window lifter prior to installation in a motor vehicle on a support plate, so that a so-called window lift module is formed, which is integrated into a motor vehicle by the carrier plate installed as a module carrier in the motor vehicle is, for example, by arranging the support plate on a motor vehicle door, comparisons DE 196 22 310 A1 , This makes it possible to pre-assemble the window regulator at a separate from the place of manufacture of the motor vehicle manufacturing plant, then to transport to the place of manufacture of the motor vehicle and install there in the motor vehicle.

Of the The invention is based on the problem, a window regulator assembly of the aforementioned type to be further improved.

This Problem is inventively by the creation a window regulator assembly having the features of claim 1 solved.

After that are the functional components of the window regulator assembly before their Proper arrangement on a motor vehicle in each case in a pre-assembly position on the associated carrier arranged that the distances between the functional components at least for a part of the viewable (possible) Function component pairs are smaller than in the intended arrangement the functional components in their functional positions on the motor vehicle.

Under the viewable (possible) functional component pairs Here are any combinations of each two of the carrier arranged functional components viewed independently of whether the two functional components interact in pairs. Of importance alone is that it is generic Functional components is, each on the flexible traction device attack the window regulator.

are under the functional components provided on the carrier, for example a cable drum, several deflection and a driver, so become the possible function component pairs through all possible combinations of two functional components formed from said plurality of functional components.

To counting the possible functional component pairs but not those that functionally form a structural unit and thereby have a fixed distance from each other, such. B. a driver and the associated cable nipple, over the driver is set on the flexible traction means.

The solution according to the invention has the advantage that the window regulator assembly preassembled on the support is in pre-assembled state has a much smaller footprint as in the state in which the functional components are intended in their respective functional position are arranged. This will the transport of the window regulator assembly considerably simplified.

By doing the individual functional components already in the preassembled state each attack on the associated flexible traction means of the window and be in operative connection with this, when installing the window regulator assembly in a motor vehicle, only the positioning of the individual Function components made in their respective functional position become; The flexible traction device is thereby more or less automatically along his intended course on the motor vehicle positioned.

The According to the invention designed window regulator assembly is particularly advantageous in those cases where the at least one driver of the window according to its intended Installation in a motor vehicle is guided freely, so its Movement determined by the connection with the flexible traction device is and no additional guideway, about in the form of a guide rail or one piece formed on a support plate guide slot, is provided, in which the driver along its guideway displaceable (positively locking) engages.

A particularly compact arrangement of the window regulator assembly in the preassembled State can be achieved when the vast majority Part of the possible functional component pairs (or even all possible functional component pairs) in the carrier Pre-assembled state have a smaller distance from each other as after proper taking of their respective Functional position on the motor vehicle.

Under The functional components can, for example, at least one cable drum be, which is wrapped by the flexible traction means and the of To drive a drive of the window lift is to the flexible To operate traction means, so that this from the drive generated adjusting torque transmits to the window pane to be adjusted.

Farther may be at least one deflecting element among the functional components be, which leads to such a deflection of the flexible traction means serves that a portion of the flexible traction device along the adjustment of the window pane to be adjusted extends.

at A so-called single-stranded window regulators are regular provided two deflecting elements, each along the adjustment the window pane to be adjusted are spaced from each other, so that between these two deflecting a Zugmittelabschnitt can extend along the said adjustment.

at In contrast, a so-called two-strand window regulator is customary four deflecting elements are provided which form two deflecting element pairs, the two deflection elements each along the adjustment the window to be adjusted are spaced from each other.

The distance between two mutually associated deflection along the adjustment of the window to be adjusted is determined by the so-called (maximum) disc lift, so the extent or the maximum distance by which the window to be adjusted can be moved along its adjustment. Therefore, the distance of mutually associated deflection along the adjustment in a motor vehicle is chosen to be as large as possible, so that a window opening when lowering the window can be completely released, which indeed requires a (maximum) Scheibenhub, the distance from the upper end of a window opening up to the lower end corresponds. In the state preassembled on the carrier, according to the invention, the distance between two mutually paired deflecting elements can now be chosen to be significantly smaller (as the distance determining the slice stroke after their intended installation in a motor vehicle), so that the space requirement of the arrangement is reduced accordingly in the preassembled state.

Farther can be found among the functional components that use the flexible traction device are in operative connection, be at least one driver, on the one hand, z. B. in a known manner via a so-called cable nipple, connected to the flexible traction means and on the other hand the window pane to be adjusted is connected.

alternative for arranging a driver on the support of the window regulator assembly can z. B. also only at least one provided on the flexible traction means Cable nipple as a functional component of the window lifter on the carrier be pre-assembled, at which then only at or after installation of the Window lifter is fixed in a motor vehicle a driver.

Regarding the functional components in the form of a driver or a cable nipple It should be noted that during operation of the window lifter Distance from the other functional components, such. B. the deflecting elements, is not constant, since the cable nipple and driver in the operation of the Windows are moved together with the flexible traction means. The comparison of the distance of a driver or cable nipple of relates to other functional components of the window lift assembly Therefore, always on a specific position of the driver or Cable nipples on the flexible traction device, approximately to a middle position between two spaced apart along the direction of adjustment Deflection elements installed in a motor vehicle state of Driver.

expedient is among the functional component pairs for whose functional components the Distance in the respective pre-assembly position on the carrier is smaller than with arrangement of the functional components in theirs Functional position on a motor vehicle, at least one functional component pair, its functional components for initiating one of the drive serve the drive torque generated in the flexible traction means of the window lifter and / or serve to deflect the flexible traction means, so that a Zugmittelabschnitt substantially along the adjustment extending to be adjusted window pane, wherein the functional components the at least one functional component pair z. B. selected are made of (i) at least one cable drum, that of the flexible traction means is wrapped and powered by a drive of the window regulator is to operate the flexible traction means, and (ii) off at least one deflecting element, which leads to such a deflection the flexible traction means is used, that at least one traction means section essentially along the direction of adjustment to be adjusted Window pane extends.

At least in particular for a part of the functional component pairs the distance between the functional components along the adjustment direction the window to be adjusted when arranging the functional components smaller in each case in a pre-assembly position on the carrier be as in the arrangement of the functional components in their functional position on a motor vehicle.

Farther at least for a part of the functional component pairs the distance between the functional components when arranging the respective functional component in a pre-assembly position on the Carrier at least 20%, if necessary at least 30%, at least 50% or even at least 70% smaller than when arranging the functional components in its functional position on a motor vehicle.

Farther can drive on the carrier of the window regulator assembly of the Can be arranged, for example, which serves a window lifter To drive the cable drum looped by the flexible traction means, d. H. to turn. The drive and the cable drum can do this on the one hand on opposite (opposite) Be arranged surfaces of the carrier or else in front of the same surface of the carrier.

Around the functional components arranged on the carrier for installation the window lifter in a motor vehicle in their respective functional position to be able to transfer at the motor vehicle, can z. B. be provided that at least a part of the functional components releasably connected to the carrier, about over a positive connection, z. B. in the form of a latching connection. Furthermore, a one-piece connection between the carrier and a part of the functional components, so that the functional components of the carrier are defined as breakable are, for example, by the provision of predetermined breaking points between the Functional components and the carrier. In this case, you can the carrier and the at least one piece integral functional component together in a casting tool (Injection molding tool) are produced, wherein by use the so-called multi-component technology if necessary different Materials (eg different plastics) for the Carrier on the one hand and the at least one functional component on the other hand can be provided.

When the window regulator is installed as intended in a motor vehicle, however, not all functional components provided on the support have to be transferred from their pre-assembly position into a different functional position. It is also possible that at least one of the functional components Vor assembly position and the functional position coincide; ie, this functional component remains after installation of the window regulator in a motor vehicle in its original position on the carrier. This can be z. B. at a functional component in the form of a cable drum - and also for the associated drive the window lifter - be useful.

Farther can at least a part of the functional components, so at least one of the functional components, -. B. over movably mounted on the carrier link - such be connected to the carrier that the (respective) functional component on the carrier from its pre-assembly position to a second, different positions are transferable after the intended installation of the carrier in a motor vehicle, the functional position of the functional component equivalent.

One for connecting the respective functional component with the carrier provided link can be z. B. shift and / or be pivotally mounted on the carrier and a connecting rod or form a connection lever.

Further can also be a deformable link designed be provided so that the associated functional component by Deformation of that link from its pre-assembly position transferred to the carrier in a second, different position thereof can be.

According to one Variant of the invention is the carrier of the window regulator assembly trained and provided for this purpose, together with arranged thereon functional components on a motor vehicle to be arranged and according to regulations Arrangement of the individual functional components in their functional positions on Motor vehicle to remain there. D. h., The carrier of Window regulator assembly forms according to their intended Installation in a motor vehicle a permanent part of that Motor vehicle. In this case, the carrier can also after the installation in a motor vehicle nor for receiving a part of originally pre-assembled functional components serve, such. B. a cable drum.

To In another variant of the invention, the carrier is added or after the intended installation of the individual, this preassembled functional components in the motor vehicle from the motor vehicle away; In this case, therefore, it does not form a (permanent) component of the motor vehicle.

Of the Carrier can, for example, by a support plate formed when installing the window regulator assembly in a motor vehicle in the inner skin of a motor vehicle door is integrated. Furthermore, the carrier may be in the form of an elongate element be formed in the installed state, a reinforcing strut of the motor vehicle, in particular a motor vehicle door, forms ("side impact beam").

Further the carrier may pass through a bearing cap, such as a cable drum or the power window drive, or through the window to be adjusted or by a large-scale driver (lifting rail) be formed for the windowpane.

For a space-saving design as possible on the carrier arranged window regulator assembly is the flexible traction means (in at least one loop) as close as possible to the carrier guided along, wherein the flexible traction means in addition to a component of the window regulator assembly can be wound, the after the intended arrangement of the window regulator in a motor vehicle no more than winding element for the flexible traction means is used, such. B. on a driver of Window lifter.

1a shows an assembly for a motor vehicle window lifter (hereinafter referred to as window regulator assembly), which is a carrier 1 and a plurality of functional components pre-assembled thereon.

The carrier may for example consist of plastic or metal; However, it is necessary that it has sufficient stability to hold this preassembled functional components of a window regulator. In the present embodiment, the carrier 1 advantageously made of plastic and defines a bearing cap for receiving a (having an electric motor) drive 2 the window lifter and also serves as an integral part of the carrier 1 molded cable drum housing 10 forms, in which a rope drum 3 is stored as a functional component of the window regulator. Instead of a power-operated (electromotive) drive can on the carrier 1 also a manually operable drive, for. B. in the form of a crank drive, be provided for the window.

The rope drum 3 is in such a way in the cable drum housing 10 on the carrier 1 stored that by the assigned drive 2 moved, so can be rotated about its axis of rotation. The drive 2 and the rope drum 3 are in the embodiment on mutually opposite (opposite) sides of the carrier 1 arranged.

Next to the rope drum 3 are two deflecting elements as further functional components 4 . 5 as well as a driver 6 to the carrier 1 preassembled. The two deflection elements 4 . 5 serve according to the intended installation of the window regulator in a motor vehicle, as in 1d shown, for deflecting a flexible traction means Z of the window, so that this extends with a traction means ZA along the adjustment of a window pane to be adjusted by means of the window lifter. To connect a window pane to be adjusted by means of the window lifter with the flexible traction means Z, the functional component is in the form of a driver 6 , on the one hand (in a known manner via a cable nipple of the flexible traction means Z, in a nipple recording 65 of the driver 6 engages) on the flexible traction means Z is fixed and on the other hand, the window to be adjusted is connected.

The movement of the flexible traction device Z required for an adjustment movement of the window pane, in particular a corresponding longitudinal movement of the traction mechanism section ZA (see FIG 1d ) along its direction of extension, is triggered by a rotational movement of the flexible element Z wrapped by the functional element in the form of a cable drum 3 , which with the drive 2 communicates.

Like a comparison of 1a With 1d shows, in the arrangement of the individual components of the window regulator 1a is shown after their intended installation in a motor vehicle, which has on the carrier 1 preassembled window regulator assembly a significantly smaller space requirements than the individual components of the window according to their intended installation in a motor vehicle according to 1d ,

1d shows a conventional arrangement of components of a so-called single-strand motor vehicle window lifter after its intended installation in a motor vehicle, with a drive 2 and one of these driven, wrapped by a flexible traction means Z cable drum 3 that as well as the drive 2 on a carrier 1 is arranged, and with two deflecting elements 4 . 5 for such deflection of the flexible traction means Z (in each case a guide 40 respectively. 50 of the respective deflecting element 4 . 5 ), that the flexible traction means Z with a traction means ZA along the direction of adjustment by means of the window lifter to adjustable window pane extends. The course of the Zugmittelabschnittes ZA must by no means coincide exactly with the path along which the window to be adjusted is moved during operation of the window regulator. Rather, taking advantage of the flexibility of the traction means Z web shapes can be realized for the movement of the window to be adjusted, which have deviating from the extension direction of the flexible traction means Z components, so that about a (multiple) curved path of the disc movement can be realized.

To connect the window pane to be adjusted to the traction means section ZA guided along its adjustment direction, a catch is used 6 , on the one hand - for example, in a known manner via a so-called cable nipple on the flexible traction means Z and an associated nipple chamber on the driver 6 - Is set on the traction means ZA and on the other hand, the window to be adjusted is connected.

In operation of the in 1d shown window lifter, the cable drum rotates 3 Depending on the operating direction of the (electromotive) drive 2 - along one or the other direction of rotation, which causes the cable drum 3 looping flexible traction means Z is actuated such that the traction means ZA moves along its direction of extension upwards or downwards. In each case, the driver defined at Zugmittelabschnitt ZA 6 and a window pane attached thereto, so that a window opening of a motor vehicle associated with the window pane can be closed or released by raising or lowering the window pane.

The space requirement of in 1d shown window lifter is substantially co-determined by the so-called (maximum) disk stroke by which the window pane to be adjusted along their adjustment must be movable so that the window by its adjustment of a state in which an associated window opening is completely closed, in a state , in which the window opening is completely released, can be transferred. For this disk stroke, in turn, the distance between the two deflecting elements 4 . 5 along the extension direction of the traction means ZA, ie along the adjustment of the window to be adjusted, of importance. Of course, such a space requirement of a window lifter leads to a corresponding space requirement in transport facilities, by means of which an already pre-assembled window regulator must be transferred from its production facility to a mounting location at which the window lifter is installed in a motor vehicle.

Finished Pre-assembled windows are for example on a so-called Module carrier arranged (and possibly in the preassembled state already pretested), on which they then in a motor vehicle be installed, for example by the module carrier on the inside of a motor vehicle door is set.

With the formation of a window regulator assembly as a pre-assembly of in 1a As shown, the space requirement of the window regulator assembly can be significantly reduced before it is installed in a motor vehicle.

To the in 1a illustrated compact state of a carrier 1 make preassembled power window assembly, the two deflecting elements 4 . 5 as well as the driver 6 , after proper installation of the window regulator in a motor vehicle in each case substantially from the carrier 1 , the drive provided there 2 and the cable drum mounted thereon 3 are spaced, each releasably on the carrier 1 fastened, in each case by means of a positive (latching) connection, as described below with reference to 1b and 1c will become clear.

As a result, in particular, the two deflecting elements 4 . 5 - In particular along the direction that corresponds to the intended installation in a motor vehicle of the adjustment - at a significantly lower distance from each other and also from the cable drum 3 arranged as in their respective, in 1d shown functional position.

The same applies to the distance of the driver 6 from the other functional components 3 (Cable drum) and 4 . 5 (Deflecting elements), whereby here for the comparison of the distances on the one hand on the basis of the functional position of the individual functional elements ( 1d ) and on the other hand the pre-assembly positions of the individual functional elements ( 1a ) a position of the driver 6 in the middle between the two deflection elements 4 . 5 - Based on the intended arrangement in a motor vehicle according to 1d - is used as a basis. (The position of the driver 6 between the two deflecting elements 4 . 5 - as in 1d shown - of course depends on the current setting of the driver 6 to be connected and from the window to be adjusted window pane. For a defined comparison of the arrangement 1d , which corresponds to the introduced into a motor vehicle state of the window, with the arrangement of 1a , which corresponds to a preassembled state of the window regulator assembly is here from the above-described center position of the driver 6 between the two deflecting elements 4 . 5 along the adjustment direction, ie, the extension direction the Zugmittelabschnittes ZA assumed.)

Furthermore, it is based on 1a clearly that the flexible traction Z placed in at least one loop on the carrier 1 or runs along the immediate vicinity, wherein the flexible traction means Z not only the cable drum 3 wraps around and at the deflecting elements 4 . 5 and the driver 6 is guided, but additionally by means of holding elements 14 additionally also directly on the carrier 1 is guided in order to achieve the most space-saving course of the flexible traction means Z on the carrier and in its immediate vicinity.

As in the in 1a shown pre-assembled state of the wearer 1 together with the drive 2 as well as the other functional components 3 . 4 . 5 . 6 in the form of a rope drum 3 , two deflecting elements 4 . 5 and a driver 6 the window regulator assembly is already equipped with the associated flexible traction means Z, which is the cable drum 3 wraps, which by means of the deflecting elements 4 . 5 is guided and which also with the driver 6 engages, forms the window regulator assembly 1a already an essentially functional window, its deflection 4 . 5 and takers 6 only have to be transferred to their destination position when the power window assembly is installed in a motor vehicle.

1b shows the power window assembly 1a when installed in a motor vehicle, wherein the deflecting elements 4 . 5 as well as the driver 6 and the flexible traction means Z from their attachment points on the carrier 1 be solved to the said functional components 4 . 5 . 6 as well as to be able to transfer the flexible traction means Z into their determination positions on a motor vehicle, as in FIG 1c shown.

Based 1b will further be clear that laying down the deflecting elements 4 . 5 on the carrier 1 in a respective preassembly position positive locking or latching areas 12 in the form of recesses on the carrier 1 are provided, in which the deflection 4 . 5 can engage. In a similar way is the driver 6 a locking pin 11 on the carrier 1 assigned to the driver 6 in its pre-assembly position with a recess 61 for producing a positive locking connection receives.

1d Finally, the power window is displayed on the base of the power window assembly 1a after its intended installation in a motor vehicle, for. B. on the door inner skin I a motor vehicle door. The carrier 1 When installed, it continues to hold the drive 2 as well as in the cable drum housing 10 of the carrier 1 rotatably mounted cable drum 3 and is going through in 1b not shown fastening means, which mounting holes 15 on the carrier 1 reach through, attached to the inner door skin I of a motor vehicle. The two deflection elements 4 . 5 are so in the motor vehicle, here on the inner door skin I, positioned that between the two deflection elements 4 . 5 an elongate traction means section ZA runs along the adjustment direction of the window pane to be adjusted, the length of this traction means section ZA, ie the distance between the two deflecting elements 4 . 5 along that traction means section ZA, the maximum disc lift of the windows to be adjusted by the window pane substantially co-determined.

In the 1a arrangement shown to form a space-saving, preassembled window regulator assembly is particularly advantageous applicable to a window without a guide rail, ie, a window, in which - as in 1d shown - the driver 6 on the flexible traction means Z and a traction means ZA is guided freely, without that it would be additionally guided (positively and along the extension direction of the traction means ZA displaceable) on a guide rail. Such guide rails can be fastened as separate components to a motor vehicle or integrally integrated in a window carrier receiving module carrier, cf. DE 196 22 310 A1 ,

Basically, the basis of the 1a to 1d but implement arrangement described in window regulators, in which the driver 6 is guided longitudinally movable by means of a guide device (guide rail). The guide device then serves in particular to the driver 6 imposing an adjustment, which corresponds to the desired adjustment of the window to be adjusted in the window.

In the 2a and 2 B is an example of a deflection 4 shown, which in the window of the 1a to 1d as - viewed along the adjustment - upper deflector 4 or lower deflecting element 5 can be used.

The deflecting element 4 has a guide 40 for the deflected flexible traction means Z, which with a resilient guide plate 42 is designed, which is limited deformable under the action of the streamlined after proper installation of the window regulator in a motor vehicle flexible traction means Z and so can adapt to the path of the flexible traction means Z. As based on the 1d such as 2a and 2 B becomes clear, goes the flexible traction Z after proper installation of the window in a motor driving witness at the two ends of the guide 40 respectively. 50 of the respective driver 4 . 5 in different directions from this, so that at the respective driver 4 . 5 the desired deflection of the flexible traction means is achieved and in particular one between the two deflecting elements 4 . 5 extending Zugmittelabschnitt ZA extends along the adjustment of the window to be adjusted.

For fixing the deflecting element 4 on the motor vehicle, z. B. a component of the door inner skin of a motor vehicle door, a serves on the deflection 4 arranged fastening bolts 45 (with external thread) which is assigned a fastener B in the form of a nut.

As in 2c shown, is suitable for fixing a deflecting element 4 on a component of the door inner skin I of a motor vehicle door, a keyhole attachment L with an insertion region E for insertion of the fastening bolt 45 and a fastening area O connected thereto for the final fixing of the deflecting element 4 in its functional position in the motor vehicle. The distance between the insertion region E and the attachment region O of the keyhole L (which are connected to one another via a connecting web forming a part of the keyhole L) is selected such that during the transfer of the deflection element 4 from the insertion area E in the attachment area O of the keyhole H L the flexible traction means Z is tightened, as described below with reference to 6a and 6b will be explained in more detail.

Based on 2a to 2c is still recognizable that the deflection 4 a stop area 44 is provided, which serves as anti-rotation, namely for non-rotatably receiving the mounting bolt 45 the deflecting element 4 in the attachment area O of the keyhole attachment L.

Based on 3a and 3b It is shown that the functional component fixed to the traction means section ZA of the flexible traction device Z does not necessarily have to be a driver, but that in the preassembled state of the window regulator assembly initially only a cable nipple is required 7 may be provided on the traction means ZA, thereby in a pre-assembly on the carrier 1 it can be stated that he is in a (on an extension 13 of the carrier 1 provided) latching opening 13a intervenes.

Only at a later date, for. B. at or after the installation of the window regulator in a motor vehicle, then the traction means ZA is with a driver 6 provided, in the nipple chamber 65 the rope nipple 7 engages the driver 6 defined with the flexible traction means Z or more precisely to connect the traction means ZA. Based 3c is also apparent that the driver 6 a recording area 60 for a window pane to be adjusted, more precisely its lower edge.

Based on 4a to 4c is shown how the additional space requirement of the flexible traction device Z - based on the carrier and the functional components pre-assembled thereon anyway required space - is further reduced by a winding section ZW of the flexible traction means Z on a winding area 62 of the driver 6 is wound up. In 4b In this case, for the sake of clarity, the section ZW of the flexible traction means Z to be wound is also shown once without the associated carrier.

In particular based 4a It is clear that by the wrapping of the driver 6 (and not just the rope drum 3 , which is in any case necessary for the function of the window lifter) with the flexible traction means Z of the space requirement is further reduced, since the flexible traction means Z is guided here closer to the carrier than in the case of the arrangement 1a for which the course of the flexible traction means Z in 4a indicated in dashed line.

alternative or in addition to the use of a driver or a driver area as an additional winding area, on the the flexible traction means Z in the preassembled state to further Reduction of space requirements can be wound up, this can also used an (additional, separate) cable drum be arranged in a suitable manner (rotatable) on the carrier is, in particular by coaxial storage with respect to Cable drum, wherein by turning the cable drum a desired Part of the flexible traction means initially aufaufelbar is and later after transfer of the individual Functional components in their functional positions on a motor vehicle is again developable. The cable drum can then either on the carrier remain or it is removed as a functionless component thereof, z. To be used again.

Farther It is also possible with the drive of the window regulator to use it in connection with the drum itself in the preassembled state of the window regulator assembly such parts to wind the flexible traction device, during or after transfer the window regulator assembly in its operative position on a motor vehicle thereof be done again, so that they then between each Extend functional components of the window regulator assembly.

In the 5a and 5b is a schematic of a modification of the window regulator assembly 1a shown, where 5a the window regulator assembly shows in total and 5b in particular the support of the window regulator assembly.

The in the 5a and 5b shown power window assembly differs from the in 1a represented primarily by the fact that the window regulator assembly from the 5a and 5b forms a so-called two-stranded window; that is to say, a window regulator which, after being installed as intended in a motor vehicle, as in 5c shown, two Zugmittelabschnitte ZA has, each extending along the direction of adjustment of a window to be adjusted and each with a driver 6 are provided for connecting a window.

For deflection of the flexible traction means Z such that two - transversely to the adjustment from each other spaced - Zugmittelabschnitte ZA each extend along the adjustment direction, a total of four deflection elements 4 . 5 provided in pairs one of the Zugmittelabschnitte ZA are assigned, wherein the deflection elements 4 . 5 each pair along the adjustment of the window to be adjusted or the extension direction of the associated Zugmittelabschnittes ZA are arranged spaced from each other.

For pre-assembly of the four deflection elements 4 . 5 on the carrier 1 There are four recesses 12 provided, in each of the deflecting elements 4 . 5 is latched.

Other positive locking or holding areas 11 . 14 on the carrier 1 in the form of locking elements or latching hooks serve for the positive fixing of the driver 6 on the carrier 1 or for holding the flexible traction means Z on the carrier 1 ,

In the 6a and 6b is shown using the example of a single-strand window, as by using a keyhole L each time to determine the deflection 4 . 5 on the motor vehicle, for example on a component of the inner door skin I, a tightening of the flexible traction means Z can be achieved, namely, in particular with reference to 6b recognizable by transfer of the respective deflection element 4 . 5 from the insertion opening E of the respective keyhole attachment L into the functional position of the respective deflection element 4 . 5 defining fastening opening O. The latter has a greater distance from the looped by the flexible traction means Z cable drum 3 on, so that in 6b indicated by a dashed arrow transfer of the respective deflecting element 4 . 5 is connected in its functional position with a tightening of the flexible traction means Z. The after transfer of all functional components of the window regulator in their respective functional position on the deflecting elements 4 . 5 acting resultant force FR, which acts with a component along the extension direction of the Zugmittelabschnittes ZA, can in addition to the locking of the respective deflecting element 4 . 5 be used in its operative position by the edge of the respective attachment opening O is provided with a bulge W, in which engages the deflecting element under the action of said resultant force FR. This possibly even makes it possible to dispense with additional fastening means for fixing the deflection elements 4 . 5 on the motor vehicle.

7 shows a possible embodiment of a deflecting element 4 . 5 for a window regulator assembly of the type described above, namely a deflection element with a rotatable deflection roller 46 - contrary to that on the basis of 2a and 2 B described deflecting element with a fixed guide for the flexible traction means.

The pulley 46 is between a shot 47 and a lid 48 rotatably mounted, which is characterized by locking elements 47a . 48a in the form of latching openings and latching projections can latch into each other, wherein the deflection roller 46 is recorded rotatably between them. As the axis of rotation of the pulley 46 serves a fastening bolt 45 , along with a further fastening element B in the form of a fastening nut at the same time also a determination of the entire deflecting element 4 can be done on a motor vehicle.

The recording 47 and the lid 48 at the same time form a safety rope, with the jumping off of the flexible traction means Z of the pulley 46 is preventable. Furthermore, s.der recording 47 an anti-twist device 47b recognizable.

As a guide roller can also be used a roller (coaxial with each other) at least one Auffädelrille and formed by at least one groove Umlenkrillenbereich, wherein the Auffädelrille serves for threading the flexible traction means on the pulley and the flexible traction means of the Auffädelrille the running groove (s) can be transferred, wherein in addition a tightening of the flexible traction means can take place, for example because the deflection roller in the Umlenkrillenbereich has a larger diameter than at the Auffädelrille. Furthermore, the Auffädelrille and the associated lid of the deflection roller can be configured so that the flexible traction means can only pass at a defined location of the Auffädelrille on the track groove (s); This can be done advantageously (automatically) by acting on the deflection roller, which has a rotational movement of the deflection roller result, for example by an actuation of the Window lift drive, which leads via a movement of the flexible traction means to a rotation of the deflection roller.

In 8a is another embodiment of a window regulator assembly based on a two-strand window regulator (with two drivers 6 ), Whose support 100 here is elongated trained.

On the carrier 100 are directly the two upper deflecting elements 4 arranged the two-strand window. The two other deflection elements 5 and one from the window lift drive 2 and a cable drum driven therefrom 3 existing drive unit are with the carrier 100 each connected via a shell portions H of a Bowden cover, each receiving a portion of the flexible traction means Z - to form a Bowden cable - record. The shell sections H of the Bowden cover are on the carrier 100 each area in an associated channel 101 . 102 . 103 (see 8b as well as the detailed representation according to 8c ), so that the hull sections H defined on the carrier 100 are fixed. For this purpose, the channels 101 . 102 . 103 be designed so that the hull sections H can each engage in some areas herein.

To transfer the drive 2 , the other functional components 3 . 4 . 5 . 6 and the flexible traction means Z of the window regulator assembly 8a in the in 8b recognizable functional positions, the shell sections H of the window lifter from the channels 101 . 102 . 103 of the carrier 100 taken out, so that then the drive 2 , the other functional components 3 . 4 . 5 . 6 as well as the flexible traction means Z together with the hull sections H by utilizing the flexibility of the traction means Z and the elasticity of the Bowden sheath in the respective intended functional position can be transferred to a motor vehicle.

A streamlining of the flexible traction means Z during assembly can in turn be done by a in the detailed representation according to 8c recognizable fastening bolt 45 a respective deflecting element 4 is determined by means of a Schlüssellocheinhängung on the motor vehicle.

The carrier 100 can be provided in the present case as a pure subcarrier, which is removed after completion of the assembly of the window in a motor vehicle again and this example of the two directly on the carrier 100 arranged deflecting elements 4 pull off.

In 8b is also a possible training of the wearer 100 indicated, according to the this an extension 105 with a snap-in receptacle 105a for the drive unit 2 . 3 is provided.

9a shows a window regulator assembly with a longitudinal carrier 1 which according to 9b as a so-called side impact beams in a motor vehicle door K is integrable, extending there between two opposite portions of the door structure and hereby the crash safety of the motor vehicle door K is used.

On the carrier 1 are an electric motor drive 2 and a cable drum driven therefrom 3 as a functional component of the window regulator (in front of the same side of the carrier 1 ) arranged in a position which also corresponds to their functional position after installation of the window regulator in a motor vehicle, as shown by 9b recognizable.

In addition, a further functional component 5 the window lifter in the form of a lower deflecting element already in its functional position on the carrier 1 arranged, in the embodiment even integrally formed on this. A functional component 4 in the form of an upper deflecting the window lifter is in contrast to the carrier 100 fixed in a pre-assembly position, e.g. B. positively locked.

The latter is according to the dashed arrow in 9b after installation of the carrier 1 as a side impact beam in a motor vehicle door K from its pre-assembly position on the carrier 1 transferred to its functional position on the inner door skin I of the motor vehicle door, so that then between the two deflection elements 4 . 5 a traction means section of the flexible traction means Z is defined which extends along the adjustment direction of a window pane to be adjusted, that is to say substantially along the vertical vehicle axis z (perpendicular to the vehicle longitudinal axis x). Of course, this can be done on the flexible traction means Z of the window regulator assembly 9a be already determined at a suitable point a driver or a cable nipple for such a driver.

10 shows a development of the window regulator assembly 9a for a double-stranded window regulator, wherein the elongate support 1 two form-fitting or receiving areas 12 in the form of latching recesses for positively receiving one functional component each 4 are provided in the form of an (upper) deflecting the window regulator and two other functional components 5 in the form of (lower) deflecting elements of the window lifter in each case via a connecting member 18 , here in the form of a pivotally mounted connecting lever, with the carrier 1 are connected.

With the help of first arrows P1 is in 10 indicated how the functional components 4 in Shape of (upper) deflecting elements from their pre-assembly positions on the recesses 12 of the carrier 1 be transferred to their respective functional position on a motor vehicle, said functional components 4 in the form of deflecting elements alternatively also in one piece and (via a predetermined breaking point) detachable on the carrier 1 could be formed.

Based on second arrows P2 is shown as the other functional components 5 in the form of (lower) deflecting elements by pivoting the connecting links 18 in the form of connecting levers from their pre-assembly position on the carrier 1 can be converted into their respective functional position on a motor vehicle. In this case, by targeted adjustment of the angle to which the respective link 18 is pivoted, the flexible traction means Z of the window can be tightened targeted. These are for one of the links 18 in the form of a connecting lever in 10 exemplified two different angular positions, including one dashed.

Farther It may also be the support of the window regulator assembly to a shaft reinforcement, in particular a so-called Inner shaft reinforcement, a motor vehicle door act. This can z. B. at least one upper deflecting already be preassembled in its functional position while others Function components of this first in one of their later functional position different pre-assembly position to be ordered.

11 shows a further embodiment of an elongate carrier 1 preassembled window regulator assembly for a double-stranded window, here four functional components of the window regulator assembly in the form of a respective deflection element 4 . 5 each in a recording or rest area 12 in the form of a latching recess of the carrier 1 are positively positioned and can be transferred from their respective pre-assembly in their functional position on the motor vehicle during the intended installation of the window regulator in a motor vehicle out. Of course, it may be a part of the deflection 4 . 5 also already in its final position (functional position) on the carrier 1 be arranged so that when installing the assembly in a motor vehicle no new positioning of the corresponding deflecting element 4 or 5 must be done. At least part of the deflecting elements 4 . 5 However, is to be repositioned when installing the window in a motor vehicle, so that two Zugmittelabschnitte the flexible traction means Z are formed, each extending along the adjustment of the window to be adjusted.

The flexible traction means Z is here in sections, namely in the areas not forming one along the adjustment direction extended Zugmittelabschnittes serve, in hull sections H led a Bowden cover.

To streamline the flexible traction device Z after installation of the window regulator in a motor vehicle, it can be provided, for example, that by moving (in particular pivoting) the drive assembly 2 . 3 and thus in particular the cable drum 3 a tension of the flexible traction means Z is effected. In a (longitudinally extended) carrier on which the drive of the window lifter and at least one deflecting element are already arranged in their functional position, it can be provided that the carrier is pivotable with respect to that deflecting element, in particular with respect to the axis of rotation of a deflecting element having a deflecting roller to stretch flexible traction devices.

In the 12a and 12b a power window assembly is shown in which a drive 2 comprising a drive motor 20 , a gearbox 22 as well as an (electronic) control 24 , and a cable drum 3 on opposite sides of a carrier 1 are arranged.

From the carrier 1 There are three links in total 8a . 8b . 8c in the form of pivotable on the support 1 mounted connection lever off, at the from the carrier 1 spaced end portions each have a deflecting element 4 . 5 the window is arranged. For a space-saving design of the window regulator assembly, said links extend 8a . 8b . 8c in the preassembled state of the window regulator assembly close together and one above the other, so that in particular the deflection 4 . 5 lie close together.

Furthermore belong to the in the 12a and 12b shown window regulator assembly two drivers 6 , which are each fixed to a portion of the flexible traction means Z, after normal installation of the window regulator in a motor vehicle, compare 12c and 12d , forms a traction means section extending along the adjustment direction of the window pane to be adjusted.

As by comparing the 12a and 12b , which show the window regulator assembly in the preassembled state, with the 12c and 12d , which show the window after installation in a motor vehicle, it becomes clear, the transfer of the functional elements takes place 4 . 5 in the form of deflecting elements from their pre-assembly position into their functional position by moving the connecting links 8a . 8b . 8c , specifically by panning. As a result, the deflecting elements 4 . 5 each in moves a position in which the totality of the deflecting elements 4 . 5 together with the rope drum 3 a total of two Zugmittelabschnitte ZA of the flexible traction means Z defined, each extending along the direction of adjustment of a window to be adjusted and to each of which a driver 6 is fixed.

In the present case, the cable drum takes over 3 at the same time the function of a deflecting element, so that for a double-stranded window only three functional components 4 . 5 be provided in the form of additional (classic) deflecting elements.

The connecting links 8a . 8b . 8c serve in the present case for the positioning of the deflecting elements 4 . 5 in their respective functional position on a motor vehicle and not as guide rails for guiding the driver 6 Although such a dual function is not excluded in principle.

By targeted adjustment of the angle of the connecting links 8a . 8b . 8c when pivoting a desired tightening of the flexible traction means Z can be achieved at the same time. Optionally, one of the links 8a . 8b . 8c To design particularly rigid, so that specifically on the angular positioning of this link a streamlining of the flexible traction means Z takes place.

On the outer circumference of the carrier 1 can be arranged a seal D, so that this support after installation of the window regulator assembly in a motor vehicle at the same time can take over a function in the context of (moisture-proof) separation of the so-called dry space from the wet room of a motor vehicle door.

In 13a and the associated detail according to 13b an embodiment of a window regulator assembly is shown in which functional components 3 . 4 . 5 the window lift on a support 600 are pre-assembled, which forms a driver in the form of a lifting rail for a window pane F to be adjusted. An appropriate recording 60 for the window pane F to be adjusted is in 13b indicated.

The carrier 600 in the form of a driver or a lifting rail is attached in the usual way at the bottom of the window pane F to be adjusted, for example via a clamping and / or screw and / or adhesive connection and has two transverse to the adjustment of the window to be adjusted, ie along the lower edge of the window pane F, spaced nipple chambers 65 on, over which the carrier 600 is connected to a respective Zugmittelabschnitt ZA a flexible traction means Z of the window regulator. After conversion of the carrier to be described in more detail below 600 preassembled functional components in their functional position on a motor vehicle extend the (via a respective cable nipple) with the nipple chambers 65 connected Zugmittelabschnitte ZA each along the direction of adjustment of the window to be adjusted. The inclination of the nipple chambers 65 serves to facilitate the assembly.

As indicated by the dashed arrows in 13a indicated, to be installed on the window regulator assembly according to 13a based window lifter in a motor vehicle, the total of four in pairs on the carrier 600 arranged functional components 4 . 5 in the form of a respective deflection element from the carrier 600 removed and transferred into their respective functional position on the motor vehicle, in particular on the inner skin of a motor vehicle door, so that between two mutually paired deflection elements 4 . 5 in each case a traction means section ZA runs along the desired adjustment direction of the window pane F.

Furthermore, the one electric motor drive 2 and a functional component in the form of a cable drum 3 comprehensive drive module 2 . 3 , which also in a pre-assembly position on the carrier 600 is pre-assembled, from the carrier 600 removed and transferred to a proper functional position on the motor vehicle.

By using a driver in the form of a lifting rail for receiving and forming a preassembled window regulator assembly, a functional component, which is itself in operative connection with the flexible traction means Z of the window lifter, namely serving as a driver lift rail, at the same time as a carrier for more with the flexible traction means in combination standing functional components, namely the cable drum 3 and the deflecting elements 4 . 5 , used.

In the driver on the other functional components of the window regulator assembly, such. B. deflecting elements and / or a cable drum are preassembled, it does not have to be a large-area driver in the form of a lifting rail, but this also come smaller, attacking only on a Zugmittelabschnitt driver in the 1a ff. shown in consideration. Furthermore, it can be provided that the pre-assembled on the driver functional components are removed from this before the driver is connected to a motor vehicle with the associated adjustable window pane.

14a shows a modification of the window regulator assembly 1a , according to the one on carrier 1 not just the cable drum housing 10 , but also two deflecting elements 4 . 5 and a driver 6 as with a flexible traction means operatively connected functional components of the window lifter are integrally formed. On the representation of the flexible traction device was in 14a waived.

The functional components to be brought in contact with the flexible traction means 4 . 5 . 6 In the form of deflecting elements and a driver can thereby via predetermined breaking points SB with the carrier 1 be connected, so that to a transfer of said functional components from their respective pre-assembly position on the carrier 1 in their intended functional position on a motor vehicle a simple cancel those functional components 4 . 5 . 6 is possible.

Unless the carrier 1 on the one hand and the said functional components 4 . 5 . 6 On the other hand advantageously from different materials, for example, different plastics, should be able to produce the one-piece assembly of the 14a different materials, especially different plastics, for the wearer 1 on the one hand and the functional components 4 . 5 . 6 on the other hand. For this purpose, when casting, in particular injection molding, the assembly, the so-called multi-component technique can be used according to the different plastics used in a casting tool to shape at different points of the casting tool elements of different plastic can. In this case, depending on the type of plastics used, break points SB optionally automatically form at the transition regions of different materials.

Based 14b becomes clear that the one-piece assembly made 14a can be completed with other parts, such as elastic guide plates 42 . 52 for insertion into the respective leadership 40 . 50 a deflecting element, and associated covers 43 as rope safety. Furthermore, fasteners in the form of bolts 45 . 55 and associated fastening nuts B shown, via which the deflecting elements 4 . 5 are to be fastened in their respective functional position on the motor vehicle.

15a shows a further embodiment of a window regulator assembly, wherein a plurality of functional components together with the carrier 1 are combined to form a one-piece structural unit. The carrier 1 is formed in the embodiment by a collar of a cable drum housing 10 , starting from which along two (opposite) directions each functional components 4 . 5 . 6 , The window are arranged in one piece behind the other.

Immediately on the (as well as the cable drum housing 10 preferably made of plastic) carrier 1 are two deflecting elements 5 molded, each from the carrier 1 protrude and are connected via a predetermined breaking point SB in one piece with these. To each of the two deflection elements 5 close to the outside, so along a direction away from the carrier 1 , each in one piece a driver 6 and in turn another outward deflection element 4 at, wherein between adjacent, integrally molded together functional components 5 . 6 respectively. 4 . 6 in each case a predetermined breaking point SB is formed.

The functional components 4 . 5 . 6 are on both sides of the carrier 1 each arranged in the order, more precisely molded together, in which they are transferred during installation of the window regulator in a motor vehicle successively in their functional positions, wherein the first to be brought in their functional position functional component 4 outermost (ie spaced from the carrier 1 ) and the last to be brought in their functional position functional component 5 furthest inside (ie immediately adjacent to the carrier 1 and formed directly on this) is provided.

Based 15a is further evident that the drivers 6 one nipple chamber each 65 for receiving a cable nipple of a flexible traction means and a fastening bolt 66 for introduction into a disk hole of the window to be adjusted and thus to connect the said window pane.

The collar 1 of the cable drum housing 10 , which serves as a carrier forms in the finished assembled state of the window lifter part of a bearing cap of the window lifter drive and this purpose - for example, by laser or friction welding or clips - to connect with other housing components. In the cable drum housing 10 is a function of the flexible traction Z Z wrapped functional component 3 recognizable in the form of a cable drum housing.
