Description

The invention relates to a window regulator assembly according to the preamble of claim 1 and to a guide rail according to the preamble of claim 12.

Such an assembly comprises a window lifter carrier for receiving functional components of a window lifter, with fastening areas, by means of which the window lifter carrier is to be fastened to a door structure (eg on a door component of a motor vehicle door provided with a large-area cutout), the window lifter carrier optionally being designed and may be provided to be determined on the provided with the large-area cutout door component, that the window carrier only partially covers the large area and thus leaves parts of the cutout, which are covered by other elements of the vehicle door.

The window regulator carrier serves to form a so-called window regulator module by arranging (fixed or integrally formed) components of a window lifter on the window regulator carrier which serve for adjusting a window pane of a motor vehicle door, in particular for raising and lowering the window pane. The functional components of a window lifter to be pre-assembled or preassembled on the window lifter carrier may be, for example, a window lifter drive, such as a drive motor, a gearbox to be driven therefrom, and optionally an electronic module; at least one guide rail of the window regulator as well as a flexible traction means and hereby operatively connected functional components, such as a cable drum and deflecting act.

With regard to the window carrier, it may be provided in particular (but not necessarily) that it is dimensioned so as to be integrated into a motor vehicle door when it is installed as intended in the motor vehicle door to be integrated as a door element in the motor vehicle door partially, but not completely covered (by far). (The other areas of the large-area cutout in the motor vehicle door are then covered by other door elements, such as a subframe, which can serve to accommodate additional functional components (in addition to those preassembled on the window carrier).)

It is in the window lifter support in this embodiment, therefore, not a classic door module of the type, which together with a variety hereon pre-assembled different functional components, such as a door lock, a speaker, a window, an airbag module, etc., so in a motor vehicle door is installed that it covers a large area of the vehicle door completely or at least largely (moisture-proof). Rather, the window lifter support in the present case may have such reduced dimensions that it covers a large area of the associated motor vehicle door only to a smaller extent. Such a window lifter carrier together with components of a window lifter pre-assembled thereon is also referred to as a so-called "minimodule".

The door component, to which the window carrier (is attached together with this preassembled functional components of the window lifter) so that it covers a part of a large-scale cutout of that door component, may be formed in one or more pieces. In particular, this may be a so-called door skin, which lies between the so-called wet room of the vehicle door and the drying room and thus creates an easily accessible transition between wet and dry room with its large-area cutout during assembly of the vehicle door.

In this case, the wet space of the vehicle door is that region which lies between the outer door skin, which forms the outer design surface of the vehicle door, and the inner door skin, while the dry space adjoins the interior of the vehicle against the inner door skin. After completion of the assembly of a motor vehicle door, the large-area cutout (for example in the door inner skin) is covered by further door elements in such a way that the drying space is sealed off from the wet room and, in particular, moisture can not pass from the wet room into the drying room.

The invention is based on the problem of further improving a window regulator assembly of the type mentioned at the beginning as well as a guide rail of such a window regulator assembly.

The stated object is achieved both with the window regulator assembly of claim 1 and with the guide rail of claim 12.

According to the invention, a window lifter assembly is provided, with a window lifter carrier for receiving functional components of a window pane provided for adjusting a window pane and mounting areas of the window lifter carrier, via which the window lifter carrier is to be fixed in particular in the area of a door (body) component of a motor vehicle door provided with a large-area cutout. Further two guide rails of the window lifter which are connected to one another are provided, of which a guide rail extends at least partially between the window pane to be adjusted and a door outer skin when the window cover carrier is installed as intended in the motor vehicle door and the other guide rail at least partially between the window pane and a door inner skin extends.

The window regulator carrier thus has two guide rails, one of which (first) guide rail represents an outer guide rail and the other (second) guide rail represents an inner guide rail.

The two guide rails are regularly spaced apart along a vehicle longitudinal axis. It is advantageous that the front in the vehicle longitudinal direction, z. B. A-column side guide rail is designed as an external rail to additional space in the door area z. B. for a speaker, a map pocket or bottle holder to create. The rear, z. B. B-pillar side guide rail can be advantageously designed as an inner rail, in order to place in the outer rear portion of the vehicle door space for wet room side functional components, such. B. an impact beam or a door lock to create. It can thus be optimally utilized the available space within the vehicle door and the guide rails of the window regulator assembly are easily adaptable to the individual room conditions within a motor vehicle door.

The two guide rails are connected to one another here on the window regulator carrier, preferably (only) in a lower region, viewed with respect to a vertical vehicle axle. The two guide rails are thus respectively at the area which extends in the direction of a window opening of the door structure and not connected to one another at an upper end of the respective guide rail, but only in a lower region or at their lower ends. The (immediate) connection of the two guide rails thus takes place regularly in a region of the guide rails on which the window pane to be adjusted can not be guided, so that a connection section or a (separate) connection part between the two guide rails is not in the (imaginary) of the guide rails predetermined adjustment of the window is located.

Of course, it is possible, however, to design a connecting section or a connecting part between the two guide rails lying at least partially on different sides of the window pane such that the window pane can be guided past the connecting section or connecting part at least in sections during an adjusting movement. Here, the connecting portion or the connecting part, for example, have a recess or passage opening into which a portion of the window pane in a (fully) lowered position can be inserted. Alternatively or additionally, the window pane itself may have a trimming such that the connecting section or the connecting part lies at least in a (fully) lowered position of the window pane in a recess of the window pane formed by the trimming. In the last-mentioned case, at least the sections of the window pane adjoining the trim which extend further downwards along a vertical vehicle axis can thus be arranged at least in a lowered position of the window pane next to the connecting section or the connecting part.

The window lifter carrier may be designed and provided to be fixed in the region of the door (body) component in such a way that the window lifter carrier at least partially covers the large-area cutout.

In a preferred embodiment, the window carrier with the two guide rails is designed as a preassembled unit which is to be fixed to the door component. The window regulator carrier with the two guide rails can thus be part of a double-stranded, fully assembled and functional window regulator module in which the guide rails are connected to one another via a (lower) connecting portion, preferably rigidly, while in a (upper) area spaced therefrom along a vertical vehicle axis There is no connection between the two guide rails, the guide rails thus present unconnected in this (upper) area on the preassembled window lifter carrier. In this way, the prefabricated window regulator module can be used, for example, in a door shaft defined by an outer door skin and door skin over a large area of the inner door skin, so that after insertion the two interconnected guide rails extend at least in sections on different sides of the window pane.

Furthermore, a (pre-assembled) module can be formed from the outer door skin and the window carrier by the window carrier and the outer door skin are combined to form an assembly, optionally with other stiffening elements of the vehicle door. Preferably, a removability is provided for repair purposes, so that the outer door skin and Window lifter without major difficulties can be separated again.

Finally, it is also possible to form a module with a windowpane preassembled on the window regulator and sealing elements.

It should already be noted at this point that a guide rail of a window carrier is basically understood to mean a rail which predetermines a guideway for the window pane to be adjusted. On such a guide rail can thus z. B. a slidably guided along the guide rail and connected to the window pane driver and / or the guide rail forms a guide portion, for. B. in the form of a guide channel or a Scheibenumgriffs, for a side edge of the window pane, in or on which an edge portion of the window pane is guided longitudinally displaceable.

In one embodiment, the two guide rails are each formed substantially longitudinally extended and each extend at least with a portion away from a common base of the window carrier (when installed as intended in the direction of a window opening of the door structure). An elongate section of a guide rail which extends away from this common base thus serves, for example, in particular for the sliding guidance of a driver and / or the guidance of a disk edge section. The common base of the two guide rails also provides the (rigid) connection between the two guide rails.

In one possible embodiment, the two guide rails are formed integrally with the common base.

In an alternative embodiment, at least one of the two guide rails is integrally formed with the common base and the other guide rail is attached to this base. Alternatively, it is of course possible that both guide rails are attached to a base. For attachment are basically different fasteners in question, such. As screws or rivets. Likewise, a plug connection can be provided. In the case of different components which are to be connected to one another and thus not formed integrally with one another, these can of course also be made of different materials.

In one embodiment, in each case one guide rail (in an assembled state of the window carrier support) extends away from a base part which extends substantially transversely to a longitudinal extension direction of the respective guide rail. This base part is formed, for example, on the guide rail or formed integrally with the guide rail.

A base part preferably extends in the direction of the other, spaced in the vehicle longitudinal direction guide rail, so that two base parts of two guide rails can be fixed together to form the common base of the two guide rails. By connecting a guide rail associated base part to the other guide rail (or its base part) is thus formed in a variant, the common base of the window regulator support.

According to the above explanations, it can, of course, also be provided that a base formed integrally with both guide rails forms the two base parts to be assigned to a respective guide rail or base halves in this case.

Regardless of the connection of the guide rails with the respective base part or their common base, it is preferred that the two guide rails with the base connecting them appear in a side view (that is seen in the installed state of the door outer skin or the door inner skin) substantially U-shaped ,

As already explained above, it is further provided in one embodiment that the window regulator assembly comprises a window pane to be adjusted by means of the window lifter having a trimming such that, with the window pane lowered, parts of the base of the window frame support are within a recess defined by the trimming the window pane are arranged. The trimming of the window pane on a (sub) edge facing the underside of the vehicle thus permits a layout space-saving arrangement of the base part, since this protrudes at least partially into it in a (fully) lowered position or position of the window pane. The trimming bordering and z. B. attached to a driver portions of the window can thus be at least partially passed past the base, whereby the window can be further lowered and does not hinder the base of this lowering. Such a trimming of the window pane is preferably in side view as a concave recess.

In one embodiment, it is further provided that at least one functional component of the window lifter, in particular a deflecting element for a flexible Traction means and / or parts of a window lift drive is arranged.

Alternatively or additionally, at least one abutting part of the door outer skin and / or a crash sensor can be arranged on the window lifter carrier - and thus for example on a guide rail and / or on the base. About a standing in contact with the outer door skin part of the door outer skin or the door structure can be stiffened stronger, so that in the case of a (side) crash, a part of the forces acting on the outer door skin forces of the outer door skin also initiated directly into the window lifter can be. The window carrier can thus absorb a part of the forces acting. Such a system part can be embodied, for example, as an insulating mat or abutting part in the form of a so-called "pusher" in order to act as a crash absorber on the window carrier. Furthermore, it is also possible to provide a plant part a system and support of the window carrier to a door inner skin and / or an internal door module.

On the arrangement of a crash sensor on the window lifter carrier of a window regulator assembly according to the invention can also be achieved that the crash sensor is located in a best possible position relative to the outer door skin and can be pre-assembled on the window lifter before the window lifter carrier is fixed to the door structure. A crash sensor detects a collision and can be designed, for example, as a capacitive or (ultrasonic) sound sensor. Likewise, the training in the form of a pressure, force, heat or displacement sensor (in the latter case, for example, as strain gauges) is conceivable. By means of a crash sensor is thus detected, for example, caused by a collision deformation of parts of the door structure.

In one development, the crash sensor can also be designed as a pre-crash sensor in order to detect an imminent collision. For this purpose, for example, an ultrasonic sensor can be used which scans an environment lying outside the door structure.

In one embodiment, the window regulator carrier has a receptacle on which electrical and / or electronic functional components of the window lifter are preassembled and which is covered (moisture-proof) when the window lifter carrier is installed as intended.

For closing and sealing the receptacle so that the functional components of the window lifter or the window lifter drive protected therefrom are protected, for example, areas of the outer door skin, areas of the window lifter support, areas of the inner door skin, a door inner lining, a separate cover, another structural element the motor vehicle door, such as a side impact beam, a subframe on which functional components of the motor vehicle door are preassembled, and serve a sealing film. For example, in one embodiment, the window lifter carrier may have at its base, via the two guide rails, a receptacle which accommodates moisture components to be protected and, when properly installed, is sealed tightly.

As a cover for such a recording is for example a separately applied sealing film, a separate cover part, the outer door skin or an internal module of the door structure in question.

The module located on the inside is preferably a component of the door structure, which (finally) covers and seals the large-area cut-out which is at least partially covered by the window-holder carrier inserted into the door structure. Such an internal module may for example be a further components of the door structure bearing subframe or a door inner lining. On a subframe z. B. usually arranged a speaker.

Alternatively, it can be provided that the receptacle is covered by the outer door skin. Such a receptacle in this case has an opening which faces the outside door skin when the window carrier carrier is installed as intended. If the window carrier is arranged as intended in the door structure, the outer door skin covers the receptacle, in which the at least functional component has already been arranged, sealingly from.

Regardless of whether an open side of the receptacle, over which the functional components are preassembled on the window carrier, the outer door skin facing away from or facing away from this, it is preferred that the receptacle of the window support is designed such that it is when properly installed in a motor vehicle door between a door skin and a door outer skin of the vehicle door is located. In this way, via the receptacle within a so-called wet space of the door structure, a closed, sealed space is formed on the window lifter carrier, in which electrical and / or electronic functional components can be accommodated protected against moisture.

In particular, it may be provided that a drive motor of a window regulator drive and / or control electronics and / or at least one (crash / pre-crash) sensor and / or electrical cables are arranged in the receptacle.

Furthermore, it is preferred if the receptacle is formed on the base in order to optimally utilize the available installation space within the door structure through the window carrier.

In the course of a stiffening of the door structure to be achieved with the window regulator support of a window regulator assembly according to the invention, it is further preferred in one embodiment for the window regulator support to be connected to an outside door skin of a motor vehicle door, in particular for connection to a side impact support for an outside door skin. As already stated above, the window regulator carrier thus exists as an additional stiffening or reinforcement within the door structure, which counteracts a force acting on the outer door skin (and this deforming force). Accordingly, a side impact beam is also a structural element serving to reinforce the structure of the door, which deforms only in the case of large forces, in particular in the event of a crash. The additional installation of the window carrier on such a side impact beam and optionally the connection of the window carrier with such a side impact carrier of the side impact support is supported within the door structure of the window lifter carrier. The door structure can thereby absorb greater forces until at least parts of the door structure can penetrate into the vehicle interior and injure a vehicle occupant.

Furthermore, the window carrier can at the same time serve as a stiffening element for stiffening the door structure, in particular the door outer skin, as far as they can be supported on the window lifter support. In this case, the window regulator carrier, including functional components arranged thereon, and components of the outer door skin can be arranged in particular at a distance, so that the outer door skin can come into contact only after an initial, exclusively elastic deformation with the window regulator carrier or at least one part arranged thereon. A distance of the window carrier to the outer window skin is accordingly chosen so that the outer door skin is only elastically deformable until it comes into contact with the window lifter carrier. This distance depends inter alia on the materials or combinations of materials used for the outer door skin (eg metal and / or plastic), their dimensions and their constructive integration into the motor vehicle door, such that a distance in the tenth of a millimeter range or less Millimeters can lie.

Based on the previously described embodiment with a provided at a base of the window carrier support recording a guide rail is provided according to a further aspect of the present invention according to claim 12, which itself has such a receptacle.

Thus, a guide rail for a window regulator assembly, which provides a guideway for a window to be adjusted, according to the invention provided with a base part and an elongated portion. In this case, the longitudinally extending portion extends away from the base part and on the base part a receptacle is provided, in which at least one electrical and / or electronic functional component of a window lifter is preassembled and which is covered when the guide rail is installed as intended.

The longitudinally extending section is preferably the section of the guide rail which defines the guideway for the window pane to be adjusted.

According to the preceding embodiments, the base part and the elongated section are preferably formed integrally with each other or molded together.

In one embodiment, it is provided that a guide rail according to the invention is designed as a so-called kit solution. In this context, the guide rail is designed and provided both for use as a functional component in a double-stranded window lifter and in a single-stranded window lifter.

In this case, a double-stranded window lifter is usually understood to mean a window lifter in which the window pane is to be adjusted by way of two entrainment sliders guided in each case along a guide rail. In the case of a single-stranded window regulator, the adjustment of the window pane takes place only via a single driver, which acts on the window pane and is moved along a guide rail.

About the formation of the guide rail with a recording in the z. As the power window drive or at least parts thereof (moisture-proof) can be accommodated, it can thus be provided to use this guide rail (with it preassemblable power window drive) in a double-stranded window, for example, by connecting the base part of this guide rail with another guide rail becomes. This can then also be designed and provided accordingly that the two guide rails extend in sections on different sides of the window pane. Furthermore, the same guide rail or an identically designed guide rail can also be used individually within a single-stranded window lifter. Thus, at least one electrical and / or electronic functional component, in particular a window lifter drive, can be preassembled on the receptacle of the guide rail in any case, so that the guide rail can easily function as a self-standing, preassembled unit of a single-stranded window lifter (eg in a door shaft) Door structure can be set.

Thus, a guide rail according to the invention can be designed and provided both as part of a double-stranded window regulator for a motor vehicle front door and for a single-strand window regulator for a motor vehicle rear door. As a result, the guide rail for different types of window regulators can be used and it can also be used for different motor vehicle doors the same parts.

Other possible embodiments are also given by the dependent claims.

Further advantages and features of the present invention will become apparent in the following description of exemplary embodiments with reference to the figures.

Show it:

1A - 1D in different views, two embodiments of a window regulator assembly according to the invention, in which two guide rails extend on different sides of a window pane to be adjusted;

2 schematically different arrangements for two guide rails of a possible embodiment according to the invention a window regulator assembly;

3 a partial view of two power window assemblies for a motor vehicle front door and a motor vehicle rear door, in which an analogous to the embodiment of 1A - 1D trained single guide rail is inserted with a recording bearing base in both windows.

In the 1A - 1D is a window regulator 9 together with a window pane to be adjusted 18 * shown, which has an outer and an inner guide rail, ie, a first guide rail 35 * , which as an outer guide rail after proper installation of the Fenderheberträgers 9 in a motor vehicle door between the windowpane 18 * and a door outer skin, and a second inner guide rail 36 * , which when properly installed the window support 9 in a motor vehicle door between the windowpane 18 * and a door skin lies. The adjustment of the windowpane 18 * via two associated with the window pane each driver 55 . 56 , each along a guide rail 35 * . 36 * slidably guided. The illustrated window carrier 9 is thus part of a double-stranded window regulator.

For applying an adjusting force on the two drivers 55 . 56 is a traction device 50 provided in the form of a cable or Bowden cable, the over deflecting elements 51 . 52 and optionally 57 (see 1C and 1D ) deflected in the form of pulleys and a cable drum 43 is driven. The rotatably mounted cable drum 43 in turn is powered by a window lift 4 powered by a drive motor 40 , an associated (electronic) control unit 41 (Control electronics) and one of the drive motor 40 gearbox to be driven 42 includes. At the transmission 42 is in a known manner, the rotatable cable drum 42 arranged around which the flexible traction means 50 is looped, so that by rotation of the pulley, the driver 55 . 56 along the two guide rails 35 * and 36 * for adjusting the window pane 18 * be relocated.

The two guide rails 35 * and 36 * thus define a guideway for the window to be adjusted 18 * that in the 1A . 1B and 1D each also in a maximum lowered position 18 '' is shown.

The two guide rails 35 * and 36 * each have an elongated section 35.1 * . 36.1 * up, extending from one common, the two guide rails 35 * and 36 * connecting base 90 extends away. The long stretched section 35.1 * and 36.1 * thus each forms a free end of the guide rails 35 * . 36 * from, which is in the intended installation of the window carrier 9 into a door structure in the direction of a window opening of the door structure. In this way, the two guide rails 35 * . 36 * with the respective free end of the associated elongated section 35.1 * or 36.1 * at least slightly relative to the common base 90 displaceable, so that the window pane to be adjusted 18 * arranged between them and with both drivers 55 . 56 can be connected. At the base 90 and thus in a (relative to a vertical vehicle axle) lower area are thus the two guide rails 35 * . 36 * rigid connected to each other while not connected to each other in an upper area spaced therefrom along the vertical vehicle axis. In this way, the window carrier is 9 with its at least partially on different sides of the windowpane 18 * extending guide rails 35 * and 36 * (optionally together with the window pane 18 * , the window lift drive 4 and the traction means 50 ) preassembled, so that hereby formed module of a double-stranded window lifter is functional and pre-testable and can be used in particular in a door shaft of a door structure.

About the deflecting elements 51 . 52 and 57 is the traction device 50 deflected so that ever a Zugmittelabschnitt 50a . 50b along each of the two guide rails 35 * . 36 * extends. On the window carrier 9 Furthermore, a cable furrow is provided to the flexible traction means 50 between the outer guide rail 35 * and the inside guide rail 36 * and the associated deflection elements 51 . 52 to be able to lead. Alternatively or additionally, the flexible traction means 50 at least partially guided in a Bowden sheath.

At the common base 90 the window carrier is in the embodiments of the 1C - 1D also an (additional, fifth) deflecting element 57 arranged. This preferably rotatably mounted deflection 57 serves to deflect the traction device 50 at the base 90 . 50 that the traction means 50 with two mutually substantially parallel sections on the one guide rail 35 * extends along before it over the additional deflecting element 57 to the other guide rail 36 * is redirected. The two substantially parallel to each other aligned portions of the traction device 50 in this case run along the elongated (guide) section 35.1 * the outer guide rail 35 * along. The traction device 50 is thus on the one guide rail 35 * a total of three times diverted; at a lower and at an upper end of the guide rail 35 * as well as in the area of its base part 95 ,

Every guide rail 35 * . 36 * forms in the embodiments of the 1A - 1D Furthermore, an integrally formed therewith base part 95 respectively. 96 out. A base part 95 . 96 in this case runs essentially transversely to the longitudinal direction of the associated guide rail 35 * . 36 * or their longitudinal section 35.1 * . 36.1 * so that the guide rail 35 * or 36 * in a side view substantially as L-shaped represents. By the two basic parts 95 and 96 for the formation of the window carrier 9 and its basis 90 facing each other are connected, accordingly, the window regulator carrier 9 with the two guide rails 35 * and 36 * in the side view U-shaped.

Alternatively to a connection of the two basic parts 95 . 96 for the training of the common base 90 the window carrier 9 Of course, it can also be provided, the two guide rails 35 * . 36 * together with the common base 90 to train in one piece or to shape it.

Furthermore, the window pane 18 * on her in intended installation of the vehicle underside facing the lower edge of the disc trim 18a * on to when lowering the windowpane 18 * in a lowered position 18 '' a collision with the window carrier 9 and in particular the window regulator drive provided there 4 to avoid. The trimming 18a * turns in a side view on the windowpane 18 * as a concave recess, so that in the lowered position 18 '' the windowpane 18 * Parts of the base 90 defined recording 900 are disposed within the recess or protrude into this recess.

The recording 900 is also with a peripheral boundary wall 920 provided that the functional components arranged therein - here the window lift drive 4 - enclosed on the periphery. The boundary wall 920 is thus substantially perpendicular from a bearing surface of the receptacle 900 from where the window lift drive 4 within the recording 900 is fixed. This storage area is on the side facing away from the door outer skin of the window carrier 9 accessible via an opening. By closing the opening, the receptacle is covered liquid-tight here. The cover can be provided for example by a film or by an additional, not shown here inside module of the door structure. Such an internal module may be, for example, an assembly carrier or a part of a door inner lining.

At the base 90 is also on the intended installation of the window support 9 a door outer skin side facing a (pre-) crash sensor 7 arranged. Accordingly, the window carrier 9 not only be completely pre-assembled with the functional components of the window regulator mechanism, but also with a sensor system independent thereof, before the window carrier 9 is arranged on a door structure formed by a door skin and a door outer skin. Accordingly, parts of the sensors can also be protected against moisture in the receptacle 900 be accommodated, so that these when properly installed the window support 9 are housed within a wet room of the door structure in a sealed, dry room.

As in particular on the basis of 1B and 1D is illustrated, the window carrier serves 9 in one embodiment, as an additional stiffening of the door structure. So is in the 1D on the one inside guide rail 36 * an abutment part P (a so-called "pusher") is provided, which is preferably in the case of the intended installation of the window carrier 9 on the door skin or an internal module of the door structure is applied. In this case, the abutment part P may, for example, have a flexible or elastic region, so that when the outer skin of the door is deformed, eg. B. as a result of a crash, a part of the kinetic energy also directly from the window lifter carrier 9 is recorded.

In the variant of 1D is the window carrier 9 with his base 90 (optionally via an additional joint part P) on a side impact beam 17 ' the door structure or is even connected to this. The two guide rails 35 * and 36 * rigidly interconnecting base 90 the window carrier 9 thus supports the side impact beam 17 * towards the outer door skin (in addition), leaving the base 90 acts as a crash absorber. The base 90 thus serves over the recording formed thereon 900 (with power window drive housed therein 4 and / or sensor electronics) not only a dry space formation within the wet space of the door structure, but at the same time also provides a support or stiffening area to the outer door skin, which counteracts a (further) deformation of the outer door skin.

Further, at the base 90 also be provided at least one attachment point over which the window lifter carrier 9 is intended to be determined as intended on a door outer skin or on a door inner skin.

As already explained in the introduction, the window carrier is 9 as a preassembled unit, preferably inserted into a door shaft defined by a door inner skin and an outer door skin over a large area cutout in the inner door skin. The window carrier used in the door shaft 9 is thus completely within a wet space of the door structure and covers the formed in the door skin cutout at least partially. The tight coverage of the cutout to the vehicle interior is then carried out, for example, via a separate module located inside the window carrier, which rests, at least in sections, on a rim of the door inner skin that borders the cutout.

It should be expressly pointed out at this point that an at least partial covering of the large-area cutout by the window lifter carrier 9 In the present case, it is understood that the window lifter carrier positioned on the door structure 9 Parts of the door component (eg the outer door skin) opposite the cut-out are concealed when the door component (eg the inner door skin) facing the large-area cut-out is viewed in the direction of the other door component (outer door skin). The large area cutout at least partially covering window lifter 9 can thus be arranged completely or at least partially between the two door components.

The 2 further illustrates different embodiments of a window regulator assembly according to the invention, in which two guide rails 35 * and 36 * . 35 * and 37 or 36 * and 37 at least in sections on two different sides of the window to be adjusted 18 * extend.

The two in the 2 upper embodiments illustrate in a plan view again schematically a training according to the preceding 1A - 1D in which a double-stranded window regulator by two guide rails each leading a driver 35 * and 36 * is formed. The two upper variants of the 2 thus illustrate that the two guide rails 35 * and 36 * Depending on the application and available space each can be designed either as an internal or external guide rail.

In contrast, the two variants below illustrate the formation of a single-strand window, in each case a guide rail 35 * or 36 * to guide one with the windowpane 18 * connected driver is designed and provided. An additional guide rail 37 In contrast, it is designed and provided, by a Scheibenumgriff a side edge of the window 18 * longitudinally displaceable (and sliding) to lead.

In the two lower embodiments of the 2 the guide rail forming the disk grip extends 37 at least with a section along which the windowpane 18 * is guided (a leg of the cross-sectionally substantially U-shaped profile), on another side of the window pane 18 * as the window leading the driver 35 * or 36 * ,

In all four embodiments of the shown 2 is a pair of guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 in a (lower) area (rigidly) connected to each other and unconnected in an (upper) area which, when installed as intended in the direction of a window opening of the door structure is spaced from the connected (lower) area. The two guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 Thus, in particular at a lower end rigidly connected to each other, in particular integrally formed with each other, and unconnected at an upper end. In this way, the two along a vehicle longitudinal axis spaced guide rails in the upper area still at least slightly aligned with each other and in particular easily on different door components -. B. a door skin on the one hand and a door outer skin on the other - are set. The one pair of guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 having window lifter support is preferably designed as a pre-assembled module of a double-stranded or single-stranded window, on which already the window pane 18 * adjusting functional components (in particular the window regulator drive 4 , the traction means 50 and the deflecting elements 51 . 52 . 57 ) can be arranged before the window carrier is arranged on the door structure.

The 3 further illustrates a single guide rail 36 with a base part 30 , which is designed and provided both as part of a double-stranded window regulator (for a motor vehicle front door) and for a single-stranded window regulator (for a motor vehicle rear door). The base part 30 is on the guide rail 36 preferably integrally formed or integrally formed therewith or the guide rail 36 is at the base part 30 formed.

In the case of use for a double-stranded window regulator (in the 3 shown on the left) forms the guide rail 36 together with another (optionally according to the embodiments of 1A - 1D associated with it) guide rail 35 a window regulator 3 for a window pane to be adjusted 18 * , About the (guide) section extending substantially rod-shaped away from the base part 36.1 is here again the adjustment of a window pane 18 * entrained driver along which the driver for closing the window 18 * emotional.

The two guide rails 36 and 35 can according to the 3 again be designed as each inside or outside guide rail. This is not mandatory here.

An essential aspect in the embodiment of the 3 is rather the training of the guide rail 36 with a recording 300 , in analogy to the recording 900 the embodiments of the 1A - 1D at least one electrical and / or electronic functional component (estimated from moisture) can be accommodated. So houses the recording 300 Also in this embodiment, preferably a window lift drive 4 ,

Accordingly, a power window drive in the recording 300 the guide rail 36 be pre-assembled, leaving the guide rail 36 a preassembled module of a window regulator 3 forms. This module can then either with another guide rail 35 to which a driver is also slidably guided, combined into a double-stranded window regulator or as part of a single-stranded window carrier for adjusting a window pane 19 * be used (compare right representation of 3 ). Both for the adjustment of a front and for the adjustment of a rear window pane 18 * . 19 * is thus an identical guide rail 36 usable, in addition also in particular a window regulator drive 4 in a designated recording 300 can be stored.

In the illustrated guide rails 35 * . 36 * and 37 can also be provided that this an internal, supporting core, z. B. of a metallic material, which is surrounded by an additional material. For example, such a metallic core may be encapsulated or overmolded by a plastic material. The surrounding material may further include the associated base part 30 . 95 or 96 the respective guide rail 36 . 35 * . 36 * or a common basis 90 for a pair of guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 form.

Alternatively, it is also conceivable that the respective guide rail 35 * . 36 . 36 * supporting base part 95 . 30 . 96 a metallic core or at least partially made of a metallic material and in particular the respective guide rail 35 * . 36 or 36 * molded on this base part of plastic material, in particular molded or is formed on the metallic material to form the guide rail, in particular to this injected.

Likewise, it is alternatively provided in a variant that a common basis 90 for both guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 at least partially made of a metallic material, in particular having a metallic core, and at least portions of both guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 (And not just a guide rail) are applied to the metallic material by an injection molding process, so that the base 90 and the two guide rails 35 * / 36 * . 35 * / 37 or 36 * / 37 integral with the base 90 are formed.
