description

The invention relates to a window regulator with the features according to the preamble of claim 1. Such window regulators are used in particular in the automotive field.

A window regulator of the previously known type is described in the German patent application DE 101 12 513 A1. This previously known window regulator is an arm window regulator that is optimized for curved window panes.

The invention is based on the object of specifying a window lifter in which a window pane can be installed particularly quickly and easily. This object is achieved by the characterizing features of claim 1. Advantageous embodiments of the window lifter according to the invention are specified in the subclaims.

A major advantage of the window lifter according to the invention can be seen in the fact that it has releasable and / or breakable fastening means which hold the window lifter or slides and thus the respectively associated lifting arm of the window lifter in a predetermined position. These fasteners can already be attached, for example, during the production of the window regulator. A predetermined position of the window lifter is fixed by the fastening means, so that a window pane can then be mounted very easily; the fasteners fix the delivery position of the window lifter for the subsequent assembly. In contrast to the conventional window lifters without the fastening means according to the invention, the window lifter according to the invention does not have the problem that the window lifter as a whole is "unstable". Because of the fastening means, the window lifter (s) cannot move in their respective lifting rails, that a displacement of the mechanical arrangement formed from the lifting arm and lifting rail is prevented.

An essential advantage of the window lifter according to the invention can be seen in the fact that the fastening means can be detached or broken open. As soon as the window pane is installed, the fasteners are superfluous because they would interfere with the lifting and lowering of the window pane by the window regulator or would completely prevent it. However, since the fastening means can be detached or broken open according to the invention, they can simply be removed after the window pane has been fitted, so that the fastening means cannot adversely affect the normal operation of the window lifter.

It is considered advantageous if the fastening means are designed such that they can be released or broken open by the force required to actuate the window lifter. In particular, it is advantageous if the fastening means can be released or broken open by the motor force of a drive motor of the window lifter if the window lifter is a motor-driven window lifter.

It is considered advantageous if the fastening means are arranged in such a way that they release the slider when the window pane is fastened to the lifting rail - in particular when the window pane is pushed into the lifting rail. In one In such a case, a separate subsequent removal of the fastening means is unnecessary.

According to an advantageous embodiment of the window lifter according to the invention, it is provided that the fastening means have a clamping plate which can be rotated about an axis of rotation or stretchable about an expansion axis and has two plate ends separated by the rotation axis or expansion axis, one end of the plate being arranged in such a way that it is in a first position Blocked slider and in a second position releases the slider and the other plate end is arranged such that it is deflected when the window pane is attached to the lifting rail - in particular when the window pane is inserted into the lifting rail - which then causes one plate end to be deflected from its first Position is brought into its second position.

The one and / or the other plate end can advantageously be held by a spring force such that the spring force must be overcome in order to deflect the other plate end, i. H. that in order to transfer the one end of the plate from the first position (locking position) to the second position (releasing position), the spring force must be overcome.

The other plate end is advantageously connected to a holding part of the lifting rail holding the side window in such a way that it is deflected when the window pane is pushed into the holding part. Advantageously, a rubber holder comprising the window pane is present in the holding part, which is designed in such a way that it applies the spring force which holds the holding part in the locking position (locking position of the holding part = the one plate end is in the first position).

Instead, the clamping plate can advantageously have a hole, in particular a bore, through which a fastening screw provided for fastening the window pane is passed, the hole or the hole being arranged such that when the fastening screw is tightened, the one plate end of the clamping plate is inserted into its second Position is brought.

Otherwise, it is considered advantageous if the one plate end of the clamping plate has clamping jaws which engage around the slider in the first position of the clamping plate. Instead of clamping jaws, the one plate end of the clamping plate can advantageously have a web with a latching lug which engages in a recess in the slider to fix the slider.

To fasten the locking lug of the clamping plate, the slider can advantageously have a plurality of adjacent recesses; if there are several adjacent recesses, the slider can be fastened in different positions, so that a total of a plurality of different positions of the window regulator is made possible. The lifting arms of the window lifter can thus be brought into different mounting positions with regard to different vehicle models and with regard to different doors and window panes and fixed there.

Otherwise, it is considered advantageous if the recess forms a saw-shaped structure in the slider, into which the latching lug of the clamping plate engages. Even with a saw-shaped structure, different positions of the locking lug in the slider are possible, so that the window lifter can be fixed in different positions of the lifting arm or the lifting arms.

Furthermore, it is considered advantageous if the fastening means have at least one fastening pin which locks the slider and the lifting rail together.

To lock the slider, the slider can have at least one through hole through which the fastening pin can be pushed to fix the slider and which holds the fastening pin in a force-locking manner.

To fix the fastening pin to the lifting rail, the latter can advantageously have at least one recess into which the fastening pin can be pushed in order to fix the slide.

It is advantageous if the lifting rail has an elongated hole with locking teeth arranged at regular intervals, which fix the fastening pin.

The slider can advantageously have two or four through holes, so that two or four fastening pins can be used for fixing. When using two fastening pins, it is considered advantageous if the two through holes in the slider are diagonally opposite. In the case of four through holes, it is considered advantageous if these are arranged in such a way that they form the corner points of a fictitious square.

According to a further advantageous embodiment of the window lifter according to the invention it is provided that the fastening pin forms a fastening dowel which is inserted through a hole, in particular through a hole, in the lifting rail into a hole in the slider for fixing the slider. A major advantage of such a fixing plug is the fact that it can be installed very easily.

Otherwise, it is considered to be advantageous if the fastening dowel has a locking projection which, when the fastening dowel is inserted, fastens it to the lifting rail. A major advantage of the locking approach is that when sheared - i.e. when the fastening plug is broken open - no part of the fastening plug is loose and can fall down. Loose parts are particularly disadvantageous in the motor vehicle sector, since they can lead to noise, in particular to rattling noises, when driving.

In order to enable the fastening dowel to be fastened in the glider, it is considered advantageous if the hole in the glider is a blind hole and / or at the same time acts as a stop for the fastening dowel. The hole advantageously brings about a non-positive fastening of the fastening dowel in the glider.

Otherwise, it is considered to be advantageous if the fastening dowel has a curved, elastically deformable dowel head which strikes the lifting rail when the fastening dowel is pushed in with elastic deformation. In the case of an elastically deformable dowel head, it can be achieved that when the fastening dowel is sheared off, the dowel head is spatially separated from the dowel bolt remaining in the slider due to the spring force caused by the elastic deformation of the dowel head, so that the dowel head and dowel bolt unite after shearing Distance from each other. This distance reliably prevents the dowel head and the dowel bolts from touching during the subsequent operation of the window lifter and causing squeaking noises. The fastening dowel can be fastened particularly reliably in the glider if the dowel bolt of the fastening dowel has scraper ribs which bring about a non-positive fastening of the fastening dowel in the glider.

According to another advantageous embodiment of the window lifter according to the invention it is provided that the fastening means are formed by an adhesive plug which extends through a hole in the lifting rail into a hole in the slider. In other words, in this embodiment of the invention, the lifting rail and slider are glued together. The advantage of such an adhesive connection can be seen in the fact that it can be produced in a particularly simple manner.

In addition, the fastening means can advantageously have a clip which is connected to the slider by means of a connecting piece and is clamped in the lifting rail. The clip and the slider are advantageously formed in one piece.

In addition, it is considered advantageous if the lifting rail has an elongated hole with locking elements, on which the clip can be clamped. In the case of an elongated hole, different “clip positions” are possible, so that the glider can be fixed in different positions.

In addition, the lifting rail can advantageously be inclined such that after the clip has been torn off, the connecting piece of the clip is pressed away from the slider. This pushing away forces a distance between the two clip parts, which prevents squeaking noises when the window regulator is later operated.

In addition, it is advantageous if the clip has a spring element, which pulls the clip away from the slider or pushes it away after the clip has been torn off. Such a spring element particularly reliably prevents squeaking noises during later operation of the window lifter.

The spring element can be formed by folding in a particularly simple and thus advantageous manner.

In addition, the connecting part of the clip can advantageously be bent against a pretension in order to achieve a spring action which separates the clip parts from one another after the clip has been torn off. To explain the invention:

Figure 29 shows a ninth embodiment of fasteners for the

Window lifters according to Figure 1 and FIGS. 30 and 31 show a tenth exemplary embodiment for fastening means for the window regulator according to FIG. 1.

In the figures, the same reference numerals are used for identical components for the sake of clarity.

FIG. 1 shows a door body 1 with two side door bars 11, 12, between which a cross arm window lifter 2 is arranged. The X-Z coordinates are drawn in to illustrate the vehicle axes.

The cross arm window lifter 2 comprises a drive arm 21 and a guide arm 22 as lifting arms of the window lifter. The drive arm 21 is pivotably mounted at a mounting point 29 on a base plate 3 connected to a supporting part of the door or vehicle body 1. The first drive arm end is provided with a toothed segment arch 24, in which a drive pinion 26 engages as the drive element. The drive pinion 26 is fastened on the motor shaft of a drive motor 25 or alternatively on the shaft of a crank drive for manual actuation. The attachment of the drive arm 21 to the base plate 3 and the attachment of the drive pinion 26 to the drive motor 25 is not shown in this figure.

The second drive arm end is guided in a lifting rail 20 on the lower edge of the window pane 9. By actuating the drive pinion 26, the drive arm 21 pivots around its mounting point 23, its second end moving on a circular path, moving in the lifting rail 20 and raising or lowering the window pane 9.

The guide arm 22 is pivotably articulated on a cross-arm swivel joint 23 in the central region of the drive arm 21. The first end of the guide arm 22 is guided in a guide rail 28 fastened to the base plate 3 or formed therein. The second end of the guide arm is also guided in the lifting rail 20. By pivoting the drive arm 21, the guide arm 22 pivots in the opposite direction and forms a further support point for the window pane 9 with its second arm end.

The window pane 9 is guided in a pane guide (not shown in the drawing) in the door or vehicle body 1 and therefore follows a predetermined one Deduction track.

The guidance of the two lifting arms 21 and 22 in the lifting rail 20 is effected by sliders 40 and 43 which are slidably mounted in the lifting rail 20 and can thus be displaced laterally in the longitudinal direction of the lifting rail 20.

The sliders 40 and 43 are fixed with fastening means 50 in such a way that the lifting arms 21 and 22 are held in a predetermined position. The fastening means ensures that when the window pane 9 is fastened, the two lifting arms 21 and 22 cannot “fold away” or move in any other way. The fastening means 50 are designed in such a way that they can be detached or broken open, so that the Fixation of the two lifting arms 21 and 22 can be easily removed after fastening the window pane 9. The fastening means 50 are preferably designed in such a way that they can be broken or released by the driving force of the drive motor 25 when the window lifter is started for the first time.

Exemplary embodiments for the fastening means 50 are explained in detail in the following figures. Such fasteners can also be used in other types of window regulators, for example in all window regulators as described in the above-mentioned laid-open specification.

FIG. 2 shows a first exemplary embodiment for the fastening means 50. The slider 40 has a recess 100 into which a latching lug 103 of a clamping plate 105 engages. The locking lug 103 is attached to a web 107 of the clamping plate 105. The locking lug 103 and the web 107 thus form a plate end 110 of the clamping plate 105.

Otherwise, a holding part 113 can be seen, which is connected to the lifting rail 20. This holding part 113 serves to receive and fasten a window pane, which is not shown in FIG. 2.

In addition, a rotary or stretching axis 115 is shown in FIG. The clamping plate 105 is rotated or stretched about this rotating or stretching axis 115 when the other plate end 118 of the clamping plate 105 is deflected. The other plate end 118 can be deflected automatically by inserting the side window 9 into the holding part 113. This then requires a corresponding design of the holding part 113 and the clamping plate 105. Instead it is also possible that the other plate end 118 is only deflected when a fastening screw 120 for fastening the window pane 9 is tightened.

FIG. 3 shows the exemplary embodiment for the fastening means according to FIG. 2 in a three-dimensional representation. In this case, the other plate end 118 of the clamping plate 105 has already been deflected, so that the detent 103 is notched out of the recess 100 in the slider 14. In Figure 3, the slider 40 is thus released and is no longer held by the latch 103 and thus by the clamping plate 105.

The deflection of the other plate end 118, which due to the axis of rotation 115 leads to a notching of the locking lug 103, can be effected, depending on the design of the clamping plate 105, by inserting the side window 9 into the holding part 113 or only by tightening the fastening screw 120.

For example, the holding part 113 can have a rubber holder which surrounds the window pane and is designed such that it applies a spring force which holds the holding part in the locking position as long as no side window has been inserted yet.

FIGS. 4 and 5 show a second exemplary embodiment of the fastening means 50 for the window lifter according to FIG. 1. In the second exemplary embodiment, the slider 40 has locking teeth 150, which are shown again in more detail in cross section in FIG. The web 107 with its latching lug 103 can snap into different positions or positions of the slider 40, so that the slider can be fixed in different positions in the lifting rail 20. In Figure 5, the latch 103 of the clamping plate 105 is also drawn in again for clarification.

FIG. 6 shows a third exemplary embodiment of the fastening means 50 for the window regulator according to FIG. 1. In FIG. 6, a clamping plate 105 is shown, on the one plate end of which there are clamping jaws 160 instead of a web or a detent. These clamping jaws 160 encompass the slider 40 in such a way that it is fixed in its relative position in the lifting rail 20. Otherwise, the third exemplary embodiment according to FIG. 6 corresponds to the two exemplary embodiments according to FIGS. 2 to 5. FIGS. 7 to 11 show a fourth exemplary embodiment of the fastening means for the window lifter according to FIG. 1. Thus, the lifting rail 20 into which the slider 40 is inserted can be seen in FIG. 7. The slider 40 has a bore 200 into which a pin 205 can be inserted and pushed. In FIG. 7, reference numeral 205 shows the pin in a position plugged onto the slider 40. Since the pin 205 can be pushed through the bore 200, it can be pushed into the position identified by the reference number 210 in FIG. In this position 210, a part 213 of the pin 210 protrudes from the slider 40 such that this protruding part 213 of the pin 210 locks in the lifting rail 20. For this purpose, the lifting rail 20 has recesses 215, into which the fastening pin 210 projects with its protruding part 213.

Figure 7 shows the fourth embodiment in a side view. The fourth exemplary embodiment is shown in plan view in FIG. One recognizes the lifting rail 20 and the slider 40, which locks in the recess 215 of the lifting rail with the aid of the fastening pin 210.

It can also be seen in FIG. 8 that the lifting rail 20 has further recesses which are arranged at regular intervals and form locking teeth lying next to one another. The locking teeth are identified in FIG. 8 by the reference symbol 218.

FIG. 9 shows the fastening of the fastening pin (fastening pins) 210 according to FIGS. 7 and 8 again in detail. The fastening pin 210 and the locking teeth 218, which engage in the fastening pin 210, can be seen. In order to enable this engagement of the locking teeth 218 in the fastening pin 210, the fastening pin 210 is made of a relatively soft material, for example plastic. The locking teeth 218 thus cut into the fastening pin 210 and thus part of the fastening pin 205. This cut-out part of the fastening pin 210 bears the reference number 220 in FIG. 9.

FIG. 10 shows an exemplary embodiment for a slider 40 which has two through holes 200 for fastening and passing through two fastening pins 205. FIG. 11 shows a further exemplary embodiment for a slider 40 which has four through holes 200 for fastening or passing four fastening pins 205 through.

It can be seen in FIG. 11 that four fastening pins 205 are arranged in such a way that they form end points of a fictitious square. In the case of an attachment with only two attachment pins 205, these are arranged at diagonally opposite ends of the slider 40.

FIGS. 11a and 11b show a third exemplary embodiment for a slider 40; this slider 40 has only a single through hole 200 for fastening or passing through a single fastening pin 205. For the sake of clarity, only the fastening pin 205 and the lifting rail 20 are shown in FIG. 11b; the slider 40 is not shown.

FIGS. 12 to 19 show a fifth exemplary embodiment of the fastening means for the window regulator according to FIG. 1. These fastening means contain a fastening dowel which can be used to fasten the slide in a lifting rail. Figures 12 to 19 will now be described jointly below.

FIG. 13 shows a fixing plug 250 which is inserted through a bore 253 in the lifting rail 20 into a hole 255 in the slider 40. The hole 255 in the slider 40 has a stop 260, which can be seen particularly well in FIG. 16 and FIG. 17. Hole 255 is a blind hole.

The fastening dowel 250 has a dowel head 263, to which a locking projection 265 is assigned. The locking projection 265 is located spatially between the dowel head 263 and the end of the dowel bolt 270 of the fastening dowel 250 facing away from the dowel head 263. In order to fasten the fastening dowel 250, this has scraper ribs 273 in the region of the dowel bolt 270, which have a non-positive connection between the dowel bolt 270 and the hole Cause 255 in slider 40.

FIGS. 14 and 15 show the insertion of the fastening dowel 250 in a first phase. It can be seen that the dowel pin 250 has not yet reached the stop 260 in the hole 255 in the slider 40. FIG. 15 is a detailed illustration of FIG. 14. In the representation according to FIGS. 16 and 17 - FIG. 17 again shows a detailed representation - the dowel bolt 270 has reached the stop 260 of the hole 255. The elastically designed and deformable dowel head 263 is now pushed through and lies flat against the lifting rail 20. The cavity 280 between the dowel head 263 and the lifting rail 20, which can still be seen in FIGS. 14 and 15, has now disappeared, so that the fastening dowel 250 is under a pretension which wants to pull the dowel head 263 out of the bore 253.

FIGS. 16 and 17 also show that the locking projection 265 has now reached the space between the lifting rail 20 and the slider 40.

FIGS. 18 and 19 show what happens when the window regulator is started up for the first time. Due to the driving forces exerted on the slider 40, the fastening dowel 250 shears off at the predetermined breaking point 283 provided for this purpose, so that the fastening dowel is separated into two parts, namely into the dowel head 263 and the dowel bolt 270. The dowel pin 270 remains clamped in the hole 255 of the slider 250 due to the scraper ribs 273. The locking lug 265 prevents the dowel head 263 from falling off the lifting rail 20. The dowel head 263 thus remains clamped on the lifting rail 20 due to the locking projection 265.

As can also be seen in FIG. 19, the dowel head 263 and the dowel bolt 270 are at a distance from one another after shearing off. This distance is based on the fact that, due to the spring force of the dowel head 263, the dowel head 263 is pulled away from the slider 40 after shearing off. This spring force is based on the elastic deformation of the dowel head 263 during the insertion and pressing of the dowel head 263 in the hole 255. The springing back of the dowel head 263 in turn leads to a cavity 285 between the dowel head 263 and the lifting rail 20.

FIG. 20 shows a sixth exemplary embodiment for fastening means; these fasteners are based on an adhesive plug. 20 shows the slider 40 in the lifting rail 20, the slider 40 being fixed in its position relative to the lifting rail 20 by an adhesive plug 300. At a first When the window lifter is put into operation, this adhesive plug is sheared off, so that the connection between the lifting rail 20 and the slider 40 is broken.

FIGS. 21 to 23 show a seventh exemplary embodiment for fastening means for the window regulator according to FIG. 1; these fasteners contain a clip.

FIG. 21 shows the lifting rail 20, the slider 40 and a clip 350 in a top view. FIG. 22 shows the clip 350 in plan view in detail, and FIG. 23 shows the clip 350 in side view in cross section.

In FIG. 21 it can be seen that the clip 350 is connected to the slider 40 via a connecting piece 353. The clip 350 is inserted into a hole 356 in the lifting rail 20 and clamped there. The lifting rail 20 also has a further hole 360, into which the clip 350 could also be inserted. The lifting rail 20 according to FIG. 21 thus has two holes 356 and 360, so that when the window lifter is installed according to FIG. 21 it can be determined in which position the slider 40 is to be fixed in the lifting rail 20.

FIG. 22 shows that the clip 350 has a predetermined breaking point 363 in the connection area between its connecting piece 353 and the slider 40.

Is on the slider 40 - for example, when the

Window regulator - exerted a force, the connector 353 tears at the

Predetermined breaking point 363 from the slider 40, so that subsequently the slider 40 in the

Lifting rail 20 is freely movable.

In Figure 23, the clip 350 is shown in cross section; one recognizes a locking element

366, which fixes the clip 350 in the lifting rail 20.

FIG. 24 shows a variant for such a clip attachment. It can be seen that an elongated hole 370 is formed in the lifting rail 20 and has latching elements 373 - for example latching teeth. The clip 350 can thus be clamped anywhere in the elongated hole 370, since there are a large number of latching elements 373. Thus, in the case of a window lifter with fastening means according to FIG. 24, the slider 40 can be fixed in any position, so that the window lifter can be easily installed, for example, in different motor vehicle models. FIGS. 25, 26, 27 and 28 show an eighth exemplary embodiment for the fastening means for the window regulator according to FIG. 1. Specifically, these figures show a further embodiment of a clip 350. The connector 353 has at its end connected to the slider 40 a locking element 80 with which the connector 353 can be clamped in a hole 383 in the slider 40. The clip 350 is clamped to the lifting rail 20 in the region of a recess 386. For this purpose, the clip 350 has slots 390, the slot width of which essentially corresponds to the thickness of the sheet of the lifting rail 20. A central region 395 of the clip 350 then engages in the recess 386 of the lifting rail 20.

FIG. 28 shows the locking element 380 and the connecting piece 353 again in detail. This shows the predetermined breaking point 363 at which the connecting piece 353 tears off the slider 40.

The assembled clip 350 is shown in FIG. It can be seen that the connecting piece 353 is bent against a bias. This prestress is represented in FIG. 27 by arrow 400. Because of this pretension, the connecting piece 353 will move away from the slider 40 after tearing off at the predetermined breaking point 363 and fold back into its original target position, which is predetermined by the shape of the clip 350. Due to the pretensioning of the connecting piece 353, the clip 350 is reliably separated from the slider 40 after the connecting piece has been torn off.

A ninth exemplary embodiment for fastening means is shown in FIG. A clip connection is shown in which the lifting rail 20 and the slider 40 have an inclination angle α to one another. The angle of inclination is spanned between the fastening plane 450 of the lifting rail 20 receiving the clip and the fastening plane 455 of the slider 40. Because of the angle of inclination α, after the clip 350 has been torn off the slider 40, the connecting piece 353 of the clip 350 protrudes from the slider 40 and is therefore at a distance from it.

A distance between the connecting piece 353 of the clip 350 and the slider 40 is further increased if the clip 350 has a spring element 460 which is placed under spring tension when the slider 40 is fixed and thus after tearing off the clip leads to the connector 353 being pulled away from the slider 40.

The spring element 460 can be formed, for example, by a fold 463 in the connecting piece 353.

FIGS. 30 and 31 show - as a tenth exemplary embodiment of the invention - an exemplary embodiment for a clip 350 which is particularly suitable for mounting on the slide rail 20. The clip 350 has a latching nose 480 which is deflected when the clip 350 is inserted into a hole 483 in the lifting rail 20. The clip 350 also has a collar 490 which is attached to the top of the clip 350 and causes a stop when the clip 350 is inserted into the hole 483. A gap 496 is present between the collar 490 and the end region 493 of the latching nose 480, into which the lifting rail 20 or the sheet metal of the lifting rail 20 engages or clamps.

The combination of collar 490 and locking lug 480 or gap 496 thus results in the clip 350 being securely clamped to the fastening rail 20.
