Description

The The invention relates to an adjusting device according to the preamble of claim 1.

A Such adjusting device for adjusting an adjustment a motor vehicle has a drive device, a traction means for transmitting an adjusting force from the drive device the adjusting part and at least one deflecting element for deflecting the Pulling means on. On the deflecting element is a guide section formed, on which the traction means led to deflecting becomes.

such, for example, in the manner of a single-strand cable window lifter constructed adjusting serve z. B. for adjusting a Adjustment part in the form of a window pane in a motor vehicle door. The traction means extends in such a single-stranded Window lift from the drive device to an upper deflector is deflected by the deflecting element and extends along a Guide rail, along which a driver for connection the traction means is slidably guided with the adjusting part, towards a lower deflecting element and from there back to the drive device. During operation of the window lifter exercises the drive device has an adjusting force on the example designed as a steel cable traction means, the over the adjustment transmits the driver to the adjustment and the adjustment thus drives.

The Traction means is on the deflecting element in a guide section guided and is in operation of the adjustment such curious that the traction means can not jump from the deflection. For a simple installation of the adjustment, for example to ensure a motor vehicle door and a delivery of an easy-to-assemble, pre-assembled Adjustment unit to allow for assembly However, it must be ensured that even before attaching the Adjustment device on the motor vehicle door, the traction means is held on the deflecting elements, so that during assembly of the Adjustment not separate measures for attachment the traction means must be undertaken. The adjusting device is then assembled at the manufacturer, as a pre-assembled Unit delivered and mounted as such unit on the vehicle.

Such adjusting devices can be designed as so-called open or closed systems. In an open system, the traction means extends freely and in a non-guided manner between the drive device and the deflecting elements and, in order to ensure a proper power transmission during operation of the adjusting device, must be stretched along its entire path. In a closed, for example, from the DE 39 06 682 A1 On the other hand, known systems, for example, use Bowden systems which guide the traction means at least in sections in a Bowden tube. In these guided through Bowden systems sections, it is then not necessary to keep the traction means by a suitable tension under tension.

Around in an open system ensure that the traction means too before mounting the adjusting device on a motor vehicle door safely guided and held on the deflecting is the adjusting conventionally on a base plate arranged on which the deflecting elements are arranged and the Traction means is tensioned so that a preassembled Verstelleinrichtungseinheit with already tensioned traction means delivered as a unit is and can be mounted on the vehicle door.

at Bowden systems using closed systems is eliminated the need for such a base plate, so that the drive device on the one hand and the guide rail with the deflection on the other hand before mounting on the vehicle door do not have to be rigidly connected. Also at however, such closed systems must be ensured that the traction means by means of so-called Bowdenhalter in the area the deflecting elements is tensioned so that the traction means before assembly and in the operation of the adjusting securely to the deflecting elements is held.

All in all arises from the requirement that the traction means both before Assembly of the adjusting device on a motor vehicle door as well as in the operation of the adjustment in a strained over The deflectors must run to be safely guided and held becoming a constraint on the freedom of design and an increase in complexity and the required Number of parts of such adjustment.

Of the present invention is based on the object, an adjustment which can be constructed in the manner of an open system however, it is ensured that the traction means before assembly is held in the non-tensioned state on the deflecting element.

These The object is achieved by an object having the features of the claim 1 solved.

According to the invention, it is provided that a securing means is arranged on the deflecting element in such a way that in the region of the guide section a guide opening completely surrounding the traction means in the circumferential direction of the traction means is formed, in which the traction means is guided on the guide portion.

The Invention is based on the idea of providing a securing means, directly in the region of the deflection element, in particular in its Guide section is arranged and that in the guide section Guided traction means holds on the deflector and guaranteed. The securing means forms a guide opening from, through which the traction means is guided and the completely surrounds the traction means, so that the traction means is held on the guide section and, independently, whether the traction means in the region of the deflecting clamped or not is curious, can not jump off the deflector.

The Invention allows in this way, an adjustment to be provided in the manner of an open system, as a prefabricated unit with tensioned traction means can be delivered and assembled. The securing means allowed in particular, before the actual assembly of the adjusting device on the vehicle on a rigid connection - for example by means of a base plate - between the drive device and other components of the adjusting device, in particular the To dispense with deflecting elements so as to provide a compact, to provide a space-saving deliverable unit in which the traction means is tensioned only at and by the actual assembly. through The securing means ensures that the traction means too is held in non-tensioned state to the deflecting elements. For assembly, the adjusting device is then on the vehicle, for example a motor vehicle door, arranged and mounted, wherein the traction means is tensioned, but no separate steps to Attachment and guidance of the traction means on the deflecting elements must be undertaken. The invention thus enables a simplified assembly, increases the freedom of design such adjustment - especially there none additional components must be provided to the traction means in the region of the deflection to tension keep - and reduce the production costs.

different Embodiments of the invention Securing means are conceivable. For example, in an advantageous Design the securing means as a safety bar be formed, which is arranged on the guide portion is and the guide section at least partially closes to the outside. The safety bar is attached from the outside to the guide section and forms the guide opening in which the Traction guided and held on the guide section becomes. It is conceivable in this case to form the safety bar in such a way that he at least partially along the guide section extends and thus an elongated, the guide section enclosing enclosed guide channel. It is also conceivable in this context that the guide channel includes the entire guide section and the traction means thus on the entire length of the guide portion the deflecting element is guided. For holding the traction device However, at the deflecting element is fundamentally sufficient that the securing bracket in the form of a guide section only selectively overlapping Bridge is formed and a ring-like guide opening forms, in which the traction means out and on the guide section is held.

Of the Circlip can as a single circlip in particular in the direction of rotation of the guide section adjacent traction means centered on the guide portion be arranged. In an advantageous embodiment can but also two or more circlips on the guide section be arranged, with the securing bracket along the Guide section offset from the deflecting arranged are. In particular, it is conceivable that the securing means by exactly Form two securing bracket, which at each end of the Guiding portion of the deflecting element are arranged. The traction means thus initially extends through a first securing bracket, then passes through the guide section and then extends through a second securing bracket. By the input and output of the guide section provided Circlip will ensure that the traction means safe and reliable on the guide section along the entire length of the guide section is held. Ensure the circlips the leadership of the traction means on the guide portion this independent of the tension of the traction device before the installation of the adjusting device on a motor vehicle door and during operation of the adjusting device.

advantageously, the securing means is a positive or cohesive to the Deflecting arranged. The securing means in the form of the securing bracket can in particular be integrally formed on the deflecting element and thus be integrated directly into the deflecting element. Conceivable however, is also the securing means in the form of a separate component form, which is inserted from the outside of the deflecting element or clipped and in this way surrounding the traction means Leadership opening creates.

The guide section of the deflecting element is preferably designed as a guide groove formed in the deflecting element. The guide groove represents a recess formed in the deflection element, which receives the traction means, is adapted in its shape to the traction means and to guide the traction means extends circumferentially around the deflecting element. The deflecting element may, in particular in the region of the guide groove, be adapted in its material to the material of the traction means, for example designed as a steel cable, in order to ensure a low-friction running of the traction means about the deflecting element. It is also conceivable in this context to provide the deflecting element with a guide groove supporting roller, which forms the guide portion of the deflecting element, is rotatably mounted on the deflecting element and rolls upon movement of the traction means along the traction means to friction between the deflecting element and the traction means as far as possible to avoid. In this case, the securing means is stationary and rotationally fixed to a relative to the adjusting rotationally fixed part of the deflecting arranged so that the guide portion forming roller can rotate independently of the securing means.

at Forming the guide section as a guide groove, in which the traction device is guided, is the securing means preferably designed such that it is the guide groove at least partially closes to the outside. The securing means thus forms a section overlap the guide groove, so that in sections a guide channel or at least forms a guiding bridge, through which the traction means extends and in the guide groove is held.

In a preferred embodiment, the deflecting element on a the guide portion facing away from plug-in sections on, by means of which the deflecting element on one end of a guide rail the adjusting device can be plugged. The plug sections are here in their shape of the guide rail in such a way adapted that the mating sections provided in this Receptacles are inserted at the end of the guide rail can to the deflector with the guide rail connect to. In this context, the guide rail For example, be formed as a U-shaped channel, in the end a plug-in portion of the deflection form-fitting manner can be inserted to a mating connection between to produce the deflecting element and the guide rail. In addition to lock the connection one or more locking lugs may be provided on the plug-in sections, which engage in detent openings on the guide rail and in this way the connection between the deflector and Secure the guide rail.

In a particularly preferred embodiment is in at least one of the plug-in sections a the guide means realizing guide opening molded to guide the traction device. The the guide opening carrying plug-in section thus fulfills a dual function and serves for a connection of the deflecting element with the guide rail and on the other to secure the traction means on the deflecting element. It is conceivable in this context, the guide opening by means of a to be arranged on the plug portion, a separate To realize component representing and attachable to the plug portion securing bracket. Advantageously, however, the guide opening molded integrally into the at least one plug-in section.

The Inventive securing means forms a the traction means in the circumferential direction completely surrounding Guide opening in which the traction means on the Guide section is guided. In made-up Condition, the traction means is thus held on the deflector and can not be solved easily by the deflector. However, it also follows that the traction means for confectioning the adjusting device in the securing means, in particular in the guide opening formed by the securing means must be introduced. For example, it is conceivable if provided as a separate component formed securing means is, the securing means after the traction means around the deflector has been placed, aufzustecken on the deflector and on this Way to secure the traction means on the deflection. If the securing agent is integrally formed on the deflecting element, it is, however required, the traction means for assembly through the guide opening thread and arrange in this way on the deflection. In both cases, the guide hole adapted in shape and size of the traction device, such that the traction means slides through the securing means can be performed.

In a particularly advantageous embodiment is the securing means designed such that the traction means and a arranged on the traction means, for connecting the traction means with the drive device or the Adjustment serving nipple guided by the securing means can be. The guide opening formed by the securing means is thus formed sufficiently large and in their shape adapted to the cable nipple of the traction device such that the cable nipple and the pulling means connected to the cable nipple for arrangement pushed the deflector through the guide opening can be. After threading the traction device then the traction means by the securing means on the deflecting element held and can only be removed from the deflector by the cable nipple of the drive device or the adjustment solved and by the securing means of the deflecting element is pulled.

at a further advantageous embodiment of the invention is the Guide section formed by a spring plate, along whose traction means is guided and which the traction means during operation of the adjustment to a length compensation biases. The spring plate can hereby formed of a steel sheet be that along the deflection and by the through the Securing means completed guide opening extends and a low-friction running of the traction means on the deflection guaranteed. During operation of the adjusting acts the traction means on the spring plate and bends this, wherein the spring plate a restoring force on the traction means exercises and so a length compensation at a Seillose the traction means causes. Essential here is that too when using the spring plate, the traction means by the Securing means trained guide opening is guided, so that the traction means held on the deflecting element is.

The Securing means serves as a backup, which the traction means in the circumferential direction completely surrounds and in this way ensures that the traction means is held on the guide section. The Securing means forms a guide opening for this purpose out, in which the traction device is guided. Is the securing means formed integrally with the deflecting element Circlip realized that for himself the closed guide opening forms, that must Traction means for mounting through the guide opening be threaded, which is time-consuming and time-consuming can be. To the assembly of the traction means to the deflection to facilitate, it is therefore conceivable and advantageous, in a further embodiment the invention designed as a securing bracket securing means with a arranged on the guide rail tab for Forming the guide means surrounding the traction means to interact. The tab passes through the deflecting element and forms the circumference together with the securing bracket closed guide opening.

Of the Circlip thus encompasses the traction means for not completely, but forms only one circumferential section of the guide opening out, leaving the guide opening before mounting the deflection on the guide rail is not closed is and the traction means applied in a simple manner to the deflecting element can be. Only in mounted on the guide rail Condition of the deflector is the guide opening through the tab formed on the guide rail is closed, so that the traction means transversely to the guide section on the Deflection element is held and not more of the deflection can slide.

Of the essential advantage of the invention is that on additional Measures that the traction means before mounting the adjustment on the vehicle to keep tension, can be dispensed with. By the securing means according to the invention is Ensures that the traction device is also in the non-tensioned state at the provided for guiding the traction means deflecting elements is held, and thus it is possible, an adjustment to create in the manner of an open system that is unrestrained Traction means can be delivered for assembly.

1 shows an adjustment 1 , which is designed in the manner of a single-strand cable window lifter for adjusting a window pane forming an adjustment part in a motor vehicle door. The adjusting device 1 has a drive device 2 , a guide rail 3 and a driver 4 for connecting the adjusting device 1 with the windowpane (in 1 not shown). The driver 4 is about a traction device 5 with the drive device 2 , which may be formed as a manual or electric drive device connected, in this case is fixed to the traction means 5 coupled and sliding on the guide rail 3 guided.

The traction device 5 extends from the drive device 2 towards a first, upper deflecting element 6 at an upper end of the guide rail 3 , from the deflection element 6 along the guide rail 3 towards a second, lower deflecting element 7 and the deflecting element 7 back to the drive device 2 , The traction device 5 forms in a conventional manner a closed loop of rope, the ends for adjusting the window on a cable drum of the drive device 2 be wound up and unwound, so that the cable loop displaced at a constant length and an adjusting force of the drive device 2 on the driver 4 and the one with the driver 4 connected window pane is transmitted.

During operation of the adjusting device mounted as a window regulator on a vehicle door 1 moves the drive device 2 the traction means and exerts in this way an adjusting force on the over the driver 4 with the traction means 5 connected adjusting part in the form of the window pane. By the movement of the traction device 5 becomes the driver 4 along the guide rail 3 moved and the adjustment thus along the guide rail 3 emotional.

In 1 is the adjusting device 1 shown in a pre-assembled state before mounting on a motor vehicle door, in which the individual parts of the adjusting device are indeed composed, the drive device 2 but not rigid with the guide rail 3 is connected, so that differs from the drive device 2 around the deflecting elements 6 . 7 extending cable loop of the traction device 5 not curious. Here is the fundamental problem that the traction means 5 also in this prefabricated, non-tensioned state on the deflecting elements 6 . 7 must be kept to the adjusting device 1 Deliver in the prefabricated state and can be easily mounted on the vehicle door.

To ensure that the traction means 5 not in unstressed condition of the deflecting elements 6 . 7 can slide, securing means are provided according to the invention, which on the deflecting elements 6 . 7 are arranged and form a guide opening which completely surrounds the traction means in the circumferential direction and in which the traction means is guided on the guide means.

An embodiment of a deflecting element 6 . 7 with such a securing agent is in 2a to 2c and 3a and 3b shown. The deflecting elements 6 . 7 wise, as in 2a . 2 B and 3a is shown, a guide portion in the form of a guide groove 61 on, in which the traction means 5 in assembled condition of the adjustment 1 is guided in a smooth manner. The guide groove 61 is in the form of a recess in the deflecting element 6 . 7 molded and can in his material the material of the trained example as a steel cable traction device 5 be adapted to the most advantageous, low-friction sliding behavior of the traction device 5 on the deflecting element 6 . 7 to obtain. The guide groove 61 is in the guide direction along which the traction means around the deflecting element 6 . 7 is guided, semi-circular out forms and directs in this way, as in 1 shown, the traction means in order to a between the drive device 2 and the deflecting elements 6 . 7 To get extending cable loop, the operation of the adjustment 1 such along the guide rail 3 is moved that with the traction means 5 connected drivers 4 along the guide rail 3 sliding moves.

The deflecting elements 6 . 7 are each at one end of the guide rail 3 plugged in as in 1 shown. As from the detailed views in 2a to 2c and 3a and 3b it can be seen, has each deflecting element 6 . 7 staking portions 62 - 64 on top of the guide rail 3 facing side of the deflecting element 6 . 7 are arranged and so on the associated end of the guide rail 3 can be plugged that the deflecting element 6 . 7 at the end of the guide rail 3 is held. The guide rail 3 , which may for example be formed from a steel sheet is, as in particular from the cross-sectional view according to 2c is apparent, in the manner of a U-shaped channel 34 shaped and has lateral wall areas 31 . 33 and a middle wall area 32 on. in the inserted state is the middle plug section 63 of the deflecting element 6 . 7 in one through the channel 34 formed receptacle, leaving the wall of the guide rail 3 , as in 2c is shown, between the plug sections 62 - 64 comes to rest and is positively recorded between them. At the middle plug-in section 63 is a catch 631 formed in the inserted state, such as in particular 2 B it can be seen in a latching opening 321 in the middle wall area 32 the guide rail 3 engaged and the deflecting element 6 . 7 on the guide rail 3 locked.

The deflecting element 6 . 7 , which is preferably made of plastic for this purpose, has integrally in the two outer plug portions 62 . 64 molded guide openings 67 . 68 on, the securing bracket forming by the securing means 65 . 66 are surrounded. The circlips 65 . 66 are an integral part of the plug-in sections 62 . 64 and are integrally connected with these.

Alternatively, it is also conceivable, the safety bar 62 . 64 form as separate components that help secure the traction device 5 to the deflecting elements 6 . 7 infected and, for example by means of a clip connection with the deflecting elements 6 . 7 get connected. In this case, for example, conceivable, the circlips 65 . 66 form as metal parts to an increased pull-out of the traction device 5 from the deflection elements 6 . 7 to provide.

As especially from the perspective view obliquely from below according to 3b it can be seen have the guide openings 67 . 68 a contour which is almost trapezoidal in cross-section, whose short, inwardly facing side 671 . 681 is formed curved. This curved side 671 . 681 the guide opening 67 . 68 is in its curvature of the guide portion of the deflecting element 6 . 7 performing guide groove 61 customized. Advantageously, the curvature of the curved side 671 . 681 and the curvature of the cross section of the guide groove 61 Here, the cross-sectional shape of the traction device 5 adapted to a defined guidance of the traction means 5 on the deflecting element 6 . 7 to provide.

As in 3b As can be seen, the guide openings widen 67 . 68 outwards to the safety bars 65 . 66 towards, which allows the traction means 5 in a simple way in the guide holes 67 . 68 thread and around the deflector 6 . 7 to lay. The guide openings 67 . 68 are advantageously adapted in size and shape such that even one with the traction means 5 connected, the connection of the traction means 5 with the drive device 2 or the driver 4 Serving cable nipples together with the traction means 5 through the guide holes 67 . 68 can be performed, as described below with reference to 4a to 4f is explained in more detail.

In the embodiment according to 2a to 2c and 3a and 3b is a safety device in the form of two safety catches 65 . 66 provided at the two ends of the guide portion forming guide groove 61 are arranged and the traction means 5 thus at the two ends of the guide groove 61 in the guide groove 61 hold. Also conceivable are other embodiments of the securing means, for example in the form of a closed, the guide groove outwardly completely final guide channel or further, along the guide direction staggered securing bracket. It is essential in these different embodiments that at least in one section, the traction means 5 surrounding securing means is provided, which is the traction means 5 in the guide groove 61 of the deflecting element 6 . 7 holds.

The insertion process of the traction device 5 in the guide groove 61 is in 4a to 4f illustrated. To the adjustment 1 prefabricate (ie the traction means 5 with the deflection elements 6 . 7 and the drive device 2 to connect and the deflecting elements 6 . 7 on the guide rail 3 to arrange, without the drive device 2 but rigid with the guide rail 3 to connect like this in 1 is shown), the traction means 5 with one on the traction means 5 arranged rope nipples 51 about which the traction means 5 with a cable drum of the drive device 2 is connectable by the in one piece in the plug sections 62 . 64 molded guide openings 67 . 68 the deflecting element 6 . 7 be guided. First, this is how the transition from 4a to 4b it can be seen, the cable nipple 51 in the insertion direction E through the guide opening 67 plugged, which is designed for this purpose sufficiently large, so that the cable nipple 51 through the guide opening 67 can be performed. Subsequently, as in 4c shown, the traction means 5 around the deflecting element 6 . 7 placed and in the now opposite insertion direction E, as in 4b represented by the second guide opening 68 guided. The traction device 5 now extends through the first guide opening 67 , the guide groove 61 and the second guide hole 68 and is respectively as shown in the further perspective views of FIG 4e and 4f it can be seen in the guide groove 61 guided and through the the guide openings 67 . 68 surrounded circlips 65 . 66 on the deflecting element 6 . 7 secured. The traction device 5 with the rope nipple 51 can now continue to the deflection 6 . 7 be pulled to the rope nipple 51 with the cable drum of the drive device 2 to connect and thus the closed loop, as in 1 shown to produce.

It is conceivable in this context, first the traction means 5 in the deflection 6 . 7 introduce and then the deflecting elements 6 . 7 with the guide rail 3 to connect (see 1 ). It is also conceivable, the deflection 6 . 7 first on the guide rail 3 to arrange and only then the traction means 5 in the deflection 6 . 7 introduce. Regardless of the order of prefabrication becomes the traction means 5 in the prefabricated, non-tensioned state by the securing means in the form of the securing bracket 65 . 66 at the deflection elements 6 . 7 held.

Another embodiment of a deflecting element 6 . 7 will be explained below on the basis of 5 to 7 to be discribed. Components of the same function are, where appropriate, provided with the same reference numerals.

This in 5a and 5b illustrated deflecting element 6 . 7 has, in contrast to the deflecting element described above, a guide section forming spring plate 8th on that is located along the guide section 61 ' of the deflecting element 6 . 7 extends and on the one hand for guiding the traction means 5 on the deflecting element 6 . 7 and on the other for length compensation of the traction device 5 in a rope loose in the operation of the adjustment 1 serves.

The spring plate 8th has a center to the deflection 6 . 7 arranged leadership area 81 and end areas 82 . 83 on. The spring plate 8th extends along the deflecting element 6 . 7 and sticks out with its end areas 82 . 83 through the at the deflection 6 . 7 trained guide openings 67 . 68 That is due to between side walls 691 . 692 of the deflecting element 6 . 7 extending circlips 65 . 66 be formed. The spring plate 8th has notches on the side 84 . 85 on that with displacement fuses 611 . 612 in the form of lateral bulges on the deflecting element 6 . 7 cooperate in such a way that the spring plate 8th not relative to the deflecting element 6 . 7 can move.

During operation of the adjusting device, the traction means runs 5 , in particular from 5a it can be seen through the guide openings 67 . 68 such that the traction means 5 between the spring plate 8th and the safety bars 65 . 66 to come to rest. The spring plate 8th is here in its end areas 82 . 83 curved, so that the traction means 5 laterally supported and secure to the spring plate 8th to be led.

During operation of the adjusting device, the traction means extends 5 , analogously, for example, the 4e to the deflector 6 . 7 and acts, conditioned by the traction means 5 transmitted adjusting force, so on the spring plate 8th one that the spring plate 8th himself with his end areas 82 . 83 in the direction of the guide section 61 ' of the deflecting element 6 . 7 bends. In this bent state, the spring plate exercises 8th a restoring force on the traction means 5 suitable, the traction means 5 during operation of the adjusting device 1 to keep under tension. In particular, caused by the spring plate 8th applied restoring force, that occurs when a ropeless of the traction device 5 the spring plate 8th Relaxed until the ropeless in the traction means 5 is balanced and the through the spring plate 8th applied restoring force in equilibrium with that by the traction means 5 on the spring plate 8th is exerted force.

The spring plate 8th thus serves in the operation of the adjustment 1 on the one hand to a low-friction running of the traction device 5 on the deflecting element 6 . 7 ensure by the material of the spring plate 8th on the material of the traction device 5 is tuned. For example, the spring plate 8th For this purpose, be formed of a steel sheet, which is a low-friction run of trained, for example, a steel cable traction means 5 along the spring plate 8th allows. On the other hand, the spring plate 8th a length compensation of the traction device 8th available by the spring plate 8th resetting to that around the deflecting element 6 . 7 Guided traction means 5 acts.

In 6a and 6b are two different ways to attach the spring plate 8th on the deflecting element 6 . 7 shown.

In the embodiment according to 6a will the spring plate 8th in a direction of insertion V laterally through the guide opening 67 through in the deflection 6 . 7 inserted and so in position on the deflection 6 . 7 pushed that end area 83 of the spring plate 8th through the guide opening 68 , in 6a on the right side of the deflector 6 . 7 , from the deflecting element 6 . 7 sticking out and the notches 84 . 85 at the displacement safeguards 611 . 612 come in the form of the lateral bulges to lie. Only after inserting the spring plate 8th then becomes the traction means 5 in the deflection 6 . 7 analogous to the one in 4a to 4f illustrated process introduced.

Alternatively, as in 6b is shown, the spring plate 8th also from above into the deflecting element 6 . 7 be introduced. The spring plate 8th must this, since its length, the free opening length between the safety bars 65 . 66 on the deflecting element 6 . 7 exceeds, in a curved position 8th' , in 6b indicated schematically, between the circlips 65 . 66 be plugged in, leaving the end areas 82 . 83 of the spring plate 8th from above into and through the respective guide openings 67 . 68 can be inserted. Also in this case, the spring plate 8th in the deflecting element 6 . 7 inserted, that in the inserted position the notches 84 . 85 on the spring plate 8th at the displacement safeguards 611 . 612 to come to rest, leaving the spring plate 8th is secured in the inserted state and not relative to the deflection 6 . 7 , For example, as a result of the adjustment of the traction device 5 , can be moved.

In 7a to 7c are perspective views of the deflecting element 6 . 7 according to 5a and 5b shown, but separately without the spring plate 8th , The deflecting element 6 . 7 according to 7a to 7c corresponds in its basic structure according to the deflection element 2a to 2c , wherein the deflecting element 6 . 7 analogous to the embodiment according to FIG 2a to 2c plug-in regions 62 - 64 has, by means of which the deflecting element 6 . 7 end to the guide rail 3 can be infected to be connected to this. The circlips 65 . 66 are in the case of the deflection according to 7a to 7c however, unlike the embodiment of FIG 2a to 2c , not in one piece in the outer plug-in sections 62 . 64 molded, but in the form of itself between the side walls 691 . 692 of the deflecting element 6 . 7 extending straps formed. It is essential, however, also that the circlips 65 . 66 along with the side walls 691 . 692 and the guide section 61 ' closed guide openings 67 . 68 train, through which the traction means 5 during operation of the adjusting device 1 is guided and which the traction means 5 completely surrounded, so that the traction means 5 on the deflecting element 6 . 7 is held and not by the deflecting element 6 . 7 can jump off.

Another embodiment of a deflecting element 6 . 7 will be explained below on the basis of 8th to 12 to be discribed. Again, components of the same function, as far as appropriate, provided with the same reference numerals.

At the in 8a and 8b in perspective views illustrated arrangement, the deflecting element 6 . 7 again plug-in areas 62 - 64 on, over which the deflecting element 6 . 7 in the channel-shaped guide rail 3 is inserted end and on the guide rail 3 is held clamped. The deflecting element 6 . 7 is about a catch 631 in a latching opening 321 on the guide rail 3 engages, on the guide rail 3 secured.

To the deflecting element 6 . 7 is a spring plate 8th that laid the guiding section 61 ' of the deflecting element 6 . 7 covering and for sliding guidance of the traction means 5 serves. The spring plate 8th is in its end areas 82 . 83 curved and surrounds with these end portions 82 . 83 the deflecting element 6 . 7 so that the spring plate 8th over the end areas 82 . 83 on the deflecting element 6 . 7 held and locked securely.

The arrangement according to 8a and 8b is in 9 illustrated in an exploded view. Unlike the embodiments in 1 to 7 has the deflecting element 6 . 7 in the embodiment according to 8th to 12 a safety bar 65 ' on, extending in the manner of a projection of a base plate of the deflecting element 6 . 7 extends, but does not form a closed guide opening. Rather, the safety bar acts 65 ' in pre-assembled state - ie in a state in which the deflecting element 6 . 7 on the guide rail 3 is arranged - with a tab 35 on the guide rail 3 together so that forms the closed guide opening through which the traction means 5 then guided and by means of which the traction means 5 securely on the deflector 6 . 7 is held. The prefabricated state is in 8a and 8b shown.

For prefabrication, as in 9 First, the spring plate is illustrated 8th around the guide section 61 ' of the deflecting element 6 . 7 placed, in such a way that the end areas 82 . 83 the deflecting element 6 . 7 in the area of the outer plug-in areas 62 . 64 embrace so that the spring plate 8th securely on the deflector 6 . 7 is held. The attachment of the spring plate 8th at the Um guiding element 6 . 7 takes place in the insertion direction E 'transverse to the circumferential direction of extension of the guide section 61 ' along which the traction means 5 to slide in prefabricated condition.

In a second step, the traction means 5 around the spring plate 8th placed. By doing that, the circlip 65 ' If no closed guide opening is formed, it is possible to use the traction means 5 in the insertion direction E 'transverse to the direction of extension of the guide section 61 ' and thus across the spring plate 8th to the spring plate 8th to apply. An elaborate threading, as in the embodiments of 1 to 7 is necessary, is unnecessary.

In a third step then the deflecting element 6 . 7 with spring plate arranged thereon 8th and traction means 5 to the guide rail 3 stated. This is the tab 35 that have sections 351 . 350 with the guide rail 3 is connected and an S-shaped projection on the guide rail 3 trains through the opening 60 on the deflecting element 6 . 7 guided, so the tab 35 the deflecting element 6 . 7 be upheld. Then the deflecting element 6 . 7 in the joining direction A in the guide rail 3 pressed in, causing the plug-in areas 62 - 64 in the channel-shaped guide rail 3 be introduced and the deflection 6 . 7 over the plug-in areas 62 - 64 clamped to the guide rail 3 is attached. By inserting the deflecting element 6 . 7 in the guide rail 3 in joining direction A, the flap pushes 35 with its end area in front of the guide section 61 ' and thus comes into contact with the safety bar 65 ' that the circlip 65 ' together with the tab 35 a closed guide opening 67 trains, through which the traction means 5 guided and secure to the deflector 6 . 7 is held. The state after completion of prefabrication is in 8a and 8b shown.

Further views of this embodiment of the deflection 6 . 7 are in 10a and 10b such as 11 and 12 shown. In prefabricated state, the tab passes through 35 the opening 60 the deflecting element 6 . 7 , wherein the deflecting element 6 . 7 in its central area a recess 600 having, with the guide portion 61 ' is interrupted. In preassembled state is the guide section 61 ' through the section 351 the tab 35 closed, leaving the spring plate 8th that the leadership section 61 ' encompasses, even in the area of the recess 600 through the section 351 finds a support.

From the sectional view of 12 becomes the interaction of the tab 35 with the safety bar 65 ' clear. In prefabricated state, the tab passes through 35 the opening 60 on the deflecting element 6 . 7 and lies on the securing bracket 65 ' to that in the guide hole 67 Guided traction means 5 through the safety bar 65 ' and the tab 35 is completely surrounded and thus safe in the guide opening 67 to be led. The traction device 5 is doing at the also the guide opening 67 sweeping spring plate 8th slidably guided, wherein, as has been explained with reference to the preceding embodiments, the material of the spring plate 8th the material of the traction device 5 adapted to a low-friction guidance of the traction device 5 on the spring plate 8th to ensure.

The tab 35 is preferably integral with the guide rail 3 connected and made of the same material as the guide rail 3 (eg plastic). To meet the requirements for the strength and stability of the tab 35 to meet and secure mounting of the traction device 5 on the deflecting element 6 . 7 to ensure that is the tab 35 preferably formed of metal.

Of the The idea underlying the invention is not based on the preceding limited embodiments described. Rather, the idea of the invention can also be applied entirely Realize different kind of way. In particular, it is conceivable others Forms of securing means, for example in the form of a guide channel or in the form of several individual guide rings, it is essential that the securing means at least the traction means partially surrounds and holds in this way on the deflector. It is also conceivable, instead of the fixed, sliding guide groove to provide the deflecting a rotatable roller, the rotatable the deflecting element is arranged and in this way the friction minimized. The safety bar is then advantageously arranged on a fixed region of the deflecting element.
