Description

The The invention relates to an adjusting device for adjusting the position an adjustment part of a motor vehicle according to the preamble of Claim 1.

A Such adjusting device comprises a flexible traction means, in particular in the form of a rope, as intended to arrange in a motor vehicle is that an adjustment of the flexible traction device along an adjustment extends along the to be adjusted motor vehicle part (adjustment) between two end positions of the adjustment can be moved. This is the Adjustment part via suitable connecting means with the adjustment connected to the flexible traction means, so that the adjustment part together with the adjustment of the flexible traction means along the adjustment is moved when a force acting on the flexible traction drive, for example in the form of a drive motor and an associated, from the flexible traction device looped cable drum on the flexible Traction means acts so that this along its extension direction emotional.

at the adjustment can be, for example, a window or (serving as a sunscreen) roller blind of a motor vehicle door act, the or via a driver with the Verstellabschnitt the flexible traction means is connected. The adjustment section of flexible traction device extends along the adjustment path, along the window pane or the roller blind for opening or Closing an associated window opening of a Motor vehicle is movable. Depending on the direction of rotation of the drive and so depending on the direction of movement of the driven flexible Traction then takes place a release or closing the window opening with the window pane and / or the roller blind.

at Such an arrangement occurs in many years of operation to effects of a so-called rope elongation, that is, the flexible traction means is no longer sufficiently tight in the motor vehicle guided. The term rope elongation is not to understand that mandatory the flexible traction means itself (for Example, by stretching) increases in length and thereby forms a so-called rope loose. Rather, such an effect also on the wear of other components of a motor vehicle be due to the leadership serve the flexible traction device.

In order to ensure a reliable functioning of the adjusting device even with long-term operation, it is necessary to compensate for such effects and ensure that the flexible traction means is always sufficiently tightened to transmit applied by the adjusting drive forces on the associated adjustment part; this is referred to as rope length compensation. For this purpose, it is known to provide an elastic element, for example in the form of a compression spring, which acts on the flexible traction means in such a way that it has the tendency to tighten it. As a result, the flexible traction means is always kept under a defined voltage, which results in particular from the spring constant of the elastic element, which acts under bias directly or indirectly on the flexible traction means, cf. DE 197 00 746 A1 ,

These Type of compensation so-called elongations of the flexible However traction means can reach limits when the elastic Element to compensate for the elongations already far enough its original, pre-stressed position was deflected, that it is no longer with enough great bias on it the flexible traction device can act.

Of the The invention is therefore based on the problem, an adjustment of the type mentioned above with regard to the tightening of the flexible traction device continue to improve.

This Problem is inventively by the creation an adjusting device with the features of claim 1 solved.

After that is an area of the flexible traction device, at which the compensation engages by elongation elastic element attacks, in at least one loop placed at least two across her Extension direction arranged side by side (abutting one another or spaced) loop portions, and the elastic element acts on the in at least one loop set range of flexible traction means that the length the at least two loop sections under the action of the bias of the elastic element tends to increase. Here is the length the individual loop sections each clearly smaller than that Distance between the two end positions of the adjustment path, along which the adjusting part is movable; that is, the individual loop sections each extend only over a small part of the Total length of the flexible traction device between the two End positions of the adjustment path.

The solution according to the invention is based on a kind of "pulley principle" in that the prestressing of the elastic element is used to act on a plurality of (at least two) loop sections of a region of the flexible traction element placed in at least one loop. This can be achieved by comparatively smaller deflections of the elastic element Accordingly, the Ri siko significantly reduced that the elastic element could be so far deflected from its original position as a result of long-term operation of the adjustment that it no longer acts with sufficient restoring force on the flexible traction means to tighten this effectively.

The elastic element preferably acts on a curved Loop area in which one loop section into another Loop section goes over.

Farther are the area of the flexible laid in at least one loop Pulling means and the elastic element acting thereon are preferred arranged in or on a driver over which the to adjusting motor vehicle part with the flexible traction means or more precisely connected to the adjustment of the flexible traction means is. For this purpose, on the one hand, the driver on the flexible traction means fastened, for example, by at least one of the flexible traction means provided nipple in an associated nipple chamber of the driver engages; and on the other hand is the adjustment, so for example a windowpane or a roller blind, with the driver in a suitable Way connected. This can also be a one-piece training be provided of the driver with the respective adjustment part, the means the driver can be a one-piece on the adjustment formed part of that adjustment part.

The elastic element may according to one embodiment the invention within the at least one loop arranged be, in which the area of the flexible traction device is placed on which the elastic element attacks. On the other hand, the elastic Element also placed in at least one loop area of encompass flexible traction means, especially when the elastic Element is designed as a helical spring.

The Influence of the elastic element on the in a loop or can be placed in several loops area of the flexible traction device on the one hand directly, that is, the elastic element engages with an end portion directly on the flexible traction means at. Alternatively, an intermediate member may be provided, the such between the elastic member and the associated area of the flexible traction means is arranged, that the elastic element over that intermediate member acts on the flexible traction means.

Provided the flexible traction means (in a known manner) by means of at least two along the adjustment direction of the motor vehicle part to be adjusted (adjustment part) spaced deflecting elements, for example in the form of Pulleys, is deflected, leaving an adjustment section it flexible traction means on an adjustment along this adjustment extends, wherein the deflecting the outer Define the end positions of the adjustment path (in the adjustment direction), between where the adjustment is movable, so does the elastic element in the context of the present invention for rope length compensation not on the deflectors; d. h., there is no deflection or displacement of the deflecting elements for rope length compensation. In other words, forming the deflection elements encompassing Sections of the flexible traction means not in at least one Looped area of the flexible traction device on which the Elastic element acts.

Especially In this case, the action of the elastic element on the in at least one loop laid area of the flexible traction device no influence on the end positions of the adjustment path; these will not affected by the action of the elastic element and therefore remain constant under its effect, as well as the effective length of the adjustment between the end positions.

Further Details and advantages of the invention will become apparent in the following Description of exemplary embodiments with reference to the figures become clear.

5d an exploded view of the section 5c ,

In 4 schematically a motor vehicle window lifter is shown, which includes a drive A with a drive motor A1 and with a driven by the drive motor and rotating in operation cable drum A2.

The (electric) drive A serves as a drive for a flexible traction means 1 of the motor vehicle window lifter, in particular in the form of a cable which wraps around the cable drum A2 and which is deflected by means of two deflection elements U1, U2, which are spaced apart along an adjustment direction z, for example in the form of deflection rollers, such that an adjustment section 10 of the flexible traction device 1 along that adjustment direction z (which coincides here by way of example with the vertical vehicle axle of a motor vehicle) and forms an adjustment path for an adjusting part to be adjusted by means of the window lifter, for example in the form of a window pane FS. The two deflecting elements U1, U2 define the outer end positions of the adjustment path, between which the adjustment part in the form of a window pane FS is movable. In the present case, it is an upper end position, defined by the upper deflecting element U1, and a lower end position, defined by the lower deflecting element U2.

The window pane FS is with the adjustment 10 the flexible traction means connected via a driver M, in a known manner on the one hand (for example, via an engaging in a nipple chamber of the driver M nipple of the flexible traction means 1 ) on the flexible traction means 1 is determined and on the other hand carries the window pane FS to be adjusted (for example, by this is received by clamping between two driver parts). The driver M engages along the adjustment z movable (positive fit) in a guide rail F of the window lifter, which is just like the adjustment 10 along the adjustment direction z and thus along the adjustment path of the adjusting part to be adjusted (window pane FS) extends.

in the Embodiment is a straightforward for the sake of simplicity Course of the guide rail F shown; this can, however also along a curved path to the associated Adjustment part in the form of a window pane FS along a curved Web in a window opening into - or out a window opening out - to be able to move.

In a power window assembly of in 4 In the long-term operation of the window lifter, so-called rope extensions can occur, which have the consequence that the flexible traction means 1 no longer sufficiently streamlined between the drive A and the two deflection elements U1, U2 runs. These so-called rope extensions do not necessarily have to stretch the flexible traction device 1 be due. Rather, other effects may be responsible for this, such as wear on the deflection elements U1, U2, the driver M or the drive A, which have the consequence that the flexible traction means 1 is no longer sufficiently tight. Such rope extensions hinder the reliable transmission of the adjusting forces or Verstellmomente generated on the drive A on the adjustment FS and could in extreme cases even lead to the flexible traction means 1 from one of the deflection U1, U2 jumps off.

There are therefore measures provided to maintain the tension of the flexible traction device 1 even with years of operation to ensure. Examples of these will be described below with reference to 1a to 3b to be discribed.

1a shows by way of example the driver M of a window lifter in 4 shown in a far lowered state, that is, in a state in which the driver is located at the lower end position of the adjustment path in the region of the lower deflecting element U2. On the driver M is a closed loop loop forming flexible traction means 1 determined by means of two nipples N1, N2, which respectively engage in an associated nipple chamber of the driver M.

As based on 1a recognizable, it is the flexible traction means 1 here first an open rope; From this, however, a closed loop of rope is formed by the fact that the two ends of the rope are each provided with a nipple N1, N2 and are fixed in a respective nipple chamber of the driver M. As a result, the driver M on the flexible traction means, specifically at its adjustment 10 , attached.

The flexible traction device 1 may optionally also consist of several ropes, the ends of which are fixed to form an ultimately closed loop of rope respectively to certain, movable components of the window, such as the driver M and / or the cable drum A2.

On the driver M is in a conventional, not shown here way to be adjusted by the window to be adjusted window pane, for example by the window between two jaws of the driver M is clamped and / or by a provided on the driver M fasteners a disc hole in the The lower edge of the window pane passes through. As a result, the to be adjusted window pane FS, cf. 4 , taken from the driver M when this in the operation of the drive motor A together with the adjustment 10 of the flexible traction device 1 along the adjustment path defined by the guide rail F, in the present example along the vertical vehicle axis z, is moved.

As based on 1A can be seen, is the flexible traction device 1 or more precisely, the outgoing from the lower deflecting element U2 adjustment section 10 of the flexible traction device 1 in a provided on the driver M area 2 put in a loop so that the flexible traction means 1 there two transverse to their respective extension direction E1 and E2 spaced loop portions 21 . 22 having.

The two loop sections 21 . 22 go along a curved portion of the looped Zugmittelbereiches 2 into each other. There grabs the looped area 2 of the flexible traction means arranged on the driver elastic element 3 in the form of a compression spring, which is so under elastic bias that it has a tendency, the curved transition portion of the loop 2 (in the direction of the double arrow of the 1a ) deflect that the length of the two loop sections 21 . 22 tends to increase.

So tilts the flexible traction device 1 After prolonged operation of the window lifter to a relaxation, that is the formation of a rope loose, so does the elastic element 3 counteract this by putting it on the looped area 2 of the flexible traction device 1 acts, that it has the tendency, the two loop sections 21 . 22 to extend. As a result, the flexible traction device 1 tightened to maintain its tension.

A defined deflection of the elastic element 3 along the in 1a indicated by a double arrow direction, along the elastic bias of the elastic element 3 acts, causes equally a deflection of both loop sections 21 . 22 , Will be about the elastic element 3 over a certain period of time to streamline the flexible traction device 1 deflected by an amount dl, this leads to a corresponding extension of the two loop sections 21 . 22 in each case also essentially by the stated amount dl. The to streamline the flexible traction device 1 Delivered contribution results from the sum of the individual contributions of the two loop sections 21 . 22 as 2 · dl. A deflection of the elastic element 3 from its initial state by an amount dl thus leads to about twice the contribution for a voltage of the flexible traction device 1 ,

The position of the deflection U1, U2 and thus the end positions of the adjustment (see. 4 ) is due to the action of the elastic element 3 not affected, so that the effective length of the adjustment section 10 of the flexible traction device 1 , defined as the distance between the two deflecting elements U1, U2 or between the end positions formed thereby, remains constant.

1b shows a modification of the embodiment 1a , the difference being that here the flexible traction means 1 in its adjustment section 10 is determined only on a nipple N on the driver M. Otherwise, the two embodiments agree, in particular in the embodiment of the area placed in a loop 2 of the flexible traction device 1 , on which a provided on the driver M elastic element 3 attacks.

3a shows the adjustment section 10 a flexible traction device 1 for a motor vehicle window regulator operating in an area 2 is placed in several loops, so that in this area 2 of the flexible traction device 1 a total of five loop sections 21 . 22 . 23 . 24 . 25 (see 3b ) are juxtaposed transversely to their respective extension direction E3 or are spaced from each other. The individual loop sections 21 to 25 each go in a curved transition section of the looped area 2 into each other, these transition sections each bolt-shaped intermediate links 41 respectively. 42 embrace (entwine) along the extension direction E3 of the loop sections 21 to 25 (Which coincides with the adjustment direction z) are spaced apart from each other and so the loop portions 21 to 25 Limit on both sides along its direction of extension E3 and by one of the loop sections 21 to 25 encompassing elastic element 4 be pressed apart in the form of a helical compression spring. In other words, the helical compression spring acts 4 with each of theirs the ends in each case via one of the two intermediate links 41 or 42 on the looped area 2 of the flexible traction device 1 in each case on a curved transition portion of the looped area 2 , the associated intermediate link 41 or 42 embraces. As a result, the elastic element in the form of a helical compression spring 4 under the effect of its bias the tendency is the length of the individual loop sections 21 to 25 along its extension direction E3 to increase, as the transition from 2a to 2 B shows.

This in turn allows a streamlining of the flexible traction device 1 reach, wherein the strength of the largely constant held tension of the flexible traction means 1 in particular depends on which force (restoring or biasing force), the prestressed elastic element 4 in the form of a helical compression spring via the intermediate links 41 . 42 on the loop sections 21 to 25 of the flexible traction device 1 acts. Decisive for this is in particular the spring constant of the elastic element 4 as well as its deflection from the in 2a shown compressed starting position in the direction of the in 2 B shown largely relaxed situation.

Too strong relaxation of the elastic element 4 in the form of a helical compression spring, this can no longer with sufficient force on the flexible traction means 1 acting to the desired voltage of the flexible traction device 1 to maintain. Therefore, it is important that so-called rope extensions or ropeless of the flexible traction device 1 with the least possible relaxation (deflection) of the elastic element 4 from the in 2a shown compressed starting position can be done out. In the present case, this is made possible by each deflection (change in length) of the elastic element 4 from the in 2a shown starting position to a corresponding change in length of a plurality (namely present of five) loop portions 21 to 25 of the looped area 2 of the flexible traction device 1 accompanied. Thus, with comparatively small changes in length of the elastic element 4 comparatively large penalties are achieved.

The in the 2a and 2 B shown arrangement in which an area 2 of the flexible traction device 1 is placed in a plurality of loops, so that more than two loop sections 21 to 25 are formed, which are arranged side by side transversely to their direction of extension E, in particular in such flexible traction means is possible, which can be bent to small radii, for example in plastic ropes. In flexible traction means, which consist of steel, in contrast, an arrangement of the basis of 1a and 1b be shown type, depending on the actual flexibility of the traction device.

In the 3a and 3b is a modification of the embodiment of the 2a and 2 B shown here, where the elastic element 4 Serving coil spring - in contrast to the arrangement of the 2a and 2 B - The loop sections 21 to 25 does not surround, but rather within one of the loop sections 21 to 25 limited space is arranged. For the rest, this is true in the 3a and 3b embodiment shown with the basis of the 1a and 1b explained.

5a shows a view of a motor vehicle door T without door inner lining, which includes a door body K and above the door body K extending, defining a window opening O window frame R. In the present case, the window opening O is not only closable by means of a window pane which can be adjusted by a window lifter, but also a roller blind hanger B is provided with which the window opening O can be covered by solar radiation to protect the vehicle interior.

The Rollobehang B is in the retracted state in which it does not cover the window opening O, on a winding shaft 7 wound, which is arranged in a provided on the upper door sill of the door body K roller blind cassette. At the edge of the Rollobehangs B, which is increasingly removed when unwinding of the Rollobehangs B from the winding shaft W to cover the window opening O of the winding shaft W, a Rollozugstab S (so-called "bow") is fixed by the Rollobehang B in the usual Way against the action of the winding shaft W associated torsion spring from the winding shaft W deducted (unwound) can be to cover the window opening O.

To remove the blinds B from the winding shaft 7 the roller blind arrangement is associated with a thrust element E, which consists of a in 5b shown retracted state out of a guide rail in the form of a guide tube F of the roller blind arrangement in the in 5a dashed lines indicated extended position is movable, it takes the Rollozugstab S and thereby the Rollobehang B of the winding shaft 7 unwinds, so that the Rollobehang B covers the associated window opening O.

The pressure-resistant pusher E is according to 5b connected to a guided in the guide tube F driver M of the roller blind arrangement. This driver M is according to the 5b and 5c by means of a drive A and by means of a through the An drove A movable and deflected by a deflecting element U2 spaced from the drive A flexible traction means 1 along the extension direction z of the guide tube F movable, which defines the adjustment of the Rollobehangs B.

Any movement of the driver M along the guide rail F in the form of a guide tube, triggered by the electric motor adjustment A and transmitted by the connected to the driver M via a nipple N flexible traction means 1 , calls a corresponding movement of the pusher E along the adjustment direction z, wherein the Rollozugstange S, as shown in the 5a and 5b explained, is taken.

Based on 5c and 5d can be seen that in a section of the driver M an area 2 of the flexible traction device 1 is placed in a plurality of loops, so that a total of six along each of the adjustment z extended and transverse to this direction z adjacent or spaced apart loop sections 21 . 22 . 23 . 24 . 25 . 26 be formed.

The loop sections 21 to 26 are bounded on both sides along the extension direction z by upper and lower curved transition sections spaced apart from one another along the direction of extent z, at which in each case individual loop sections extending parallel to one another 21 to 26 merge.

In the one of the loop sections 21 to 26 and the associated transition sections of the looped area 2 of the flexible traction device 1 bounded area is an elastic element 5 arranged in the form of a compression spring, each with its two ends to an intermediate member 51 respectively. 52 acting from the upper and lower transition sections of the looped area 2 of the flexible traction device 1 is encompassed. As a result, the elastic element acts 5 in the form of a helical compression spring on the intermediate links 51 . 52 and the transition sections which wrap around the loop sections 21 to 26 of the looped area 2 a, that their length under the action of the bias of the elastic element 5 tends to increase. It arises, as well as in the previous on the basis of 1a to 3b illustrated embodiments, an equilibrium length of the elastic element 5 as well as the loop sections 21 to 26 along the direction of extension z, which depends on the spring constant of the elastic element 5 depends and for a constant tension in the flexible traction means 1 provides.

Thereby, that the elastic element 5 here about the intermediate links 51 . 52 and the curved transition sections to a total of 6 mutually parallel loop portions 21 to 26 acts, can with comparatively small changes in length of the elastic element 5 a comparatively strong tightening of the flexible traction device 1 be brought about.
