Description

The invention relates to a guide device for a cable-operated adjusting device, such as cable window lifter or pulley wiper of a motor vehicle, with at least one guide portion for guiding a driver for a window pane, a windshield wiper or the like part and at least one holder for the outer pull of the cable, which at a portion of the guide device can be arranged by means of a connecting means and with at least one positive rotation of the holder relative to the section. The invention further relates to a cable pulling device with at least one such guide device.

Technological background and state of the art

When cable winch and cable windscreen wipers usually guide rails are used, which have a guide portion for guiding a driver for the window pane or the windscreen wiper. On such guide devices deflection rollers are usually mounted to redirect the cable in such a way that an optimal connection of the cable is ensured with the driver. Since the cables used at least in sections have an outer traction, a holder is usually provided on the guide means, in which one end of the outer traction is added. By means of the support support forces of the outer train are taken and forwarded via the guide rail, for example, in the body. Like from the DE 42 40 030 A1 is known, for this purpose, the holder can be integrally formed on the guide rail.

Another possibility is that the holder is a separate component, which is mounted together with the deflection device for the cable to the guide rail. Such a generic guide device is from the WO 2008/152155 A1 known. In this known guide device, the connecting means for connecting the deflecting device to the guide device is used in order to fasten the holder to the guide device. The holder is arranged between the deflecting device and a portion of the guide device and thus rotatably supported. In order to prevent rotation of the holder relative to the guide rail, an anti-twist device is provided in the known guide device. For this purpose, the holder has at least one projection, which is on its flat side to the outside and in the assembled state on the guide means with a corresponding recess of the guide rail in operative position occurs.

In order to realize the anti-rotation in the known guide device, projections are to be formed on the support already during manufacture or attach later. Also, appropriate recesses are to be incorporated into the guide rail. The previously realized anti-rotation is therefore relatively expensive to produce.

Furthermore, from the DE 202 13813 U1 a guide rail arrangement for cable window lifter having a guide rail for guiding a driver for a window pane, and a fixed end of the guide rail with a device for guiding a cable for driving the driver. In this case, the base surface of the tail is provided at its periphery with slots, wherein in the different angular orientations of the tail of the leg of the guide rail selectively engages in one of the slots and thereby fixes the selected angular orientation of the tail.

Also from the WO 2007/142128 A1 a cable window lifter is known in which the pulleys are secured with pulley support to the vehicle body. The window of a vehicle is moved by a fixed to her, driven rope, which is partially covered by a cover. The cover is attached to a pulley carrier.

An anti-rotation between the holder and the portion of the guide device is ensured by an extension of the housing dips into a hole in the door panels.

From the US 2003/0140562 A1 an integrated cable window lifter is known. The cable pulling device consists of a guide rail with therein slidable driver for the vehicle window pane.

At the ends of the guide rails are pulleys for the rope. Each pulley has a foot which is displaceable in a corresponding guide in the longitudinal direction. Outer peripheral sections of a holder in this case come into engagement with a mating surface arranged on a section of the guide device.

task

Based on this, the present invention seeks to propose a guide device for a cable-operated adjusting device with the features mentioned, in which the holder for the outer cable of the cable is secured against rotation in manufacturing technology simple manner.

Invention and advantageous effects

To solve the problem, a guide device is proposed, which has the features mentioned in claim 1, and a cable pulling device according to claim 15.

The guide device according to the invention is suitable for cable pulling devices of any kind, in particular for cable window lifter or pulley wiper, preferably for use in motor vehicles. The guide device has at least one guide section for guiding a driver for a window pane, a windshield wiper or the like part. The guide device further has at least one holder for the outer pull of the cable pull, which can be arranged on a section of the guide device by means of at least one connecting means. Furthermore, the guide device has at least one form-locking rotation, by which the holder is secured against rotation relative to the portion of the guide device.

According to the invention, it is provided that the holder has at least two circumferential sections forming a multi-edged profile, of which at least one peripheral section comes into operative position with a corresponding mating surface or a corresponding inner circumference of the guide section in the installed state of the holder and thus prevents rotation of the guide section and holder is formed in different Verdrehlagen.

By this measure, the holder can be easily and inexpensively manufactured by a peripheral portion of the holder is used to prevent rotation. The mounted in previously known guide means on the holder projections are not required. The guide device according to the invention is thereby realized over the previously known guide device with less material.

It is advisable that the circumferential portion of the holder forming the anti-rotation device is substantially straight. Such anti-rotation allows a stable and durable securing the holder against rotation, even at relatively high acting on the support support forces of the outer pull.

According to an advantageous embodiment of the invention, it is provided that the holder has at least two peripheral portions, which can be brought into operative position with the counter surface. As a result, the holder can be mounted in at least two twisting positions relative to the section of the guide device in which the anti-twist device then also comes into operative position. As a result, the holder in a different rotational position on the guide device can be attached secured against rotation, so that an alignment of the outer pull held by the holder is made possible.

According to one embodiment of the invention, it is provided that, in the mounted state of the holder, the at least two circumferential sections, each with a corresponding mating surface, come into operative position. As a result, a particularly stable and durable rotation protection can be realized, since a plurality of peripheral portions are held against rotation.

It is advisable that seen in the circumferential direction, the at least two peripheral portions are behind one another and preferably adjacent peripheral portions are arranged at an angle to each other. It is also advisable that the peripheral portions form a multi-sided profile and preferably the circumference of the holder is at least partially formed by the profile. These measures also aim to realize a particularly stable and durable rotation, by which the holder is held against rotation even at the highest forces acting through the cable on the guide device.

According to a further embodiment of the invention, it is provided that the profile is formed mirror-symmetrically with respect to at least one axis transverse to the axis of rotation of the holder. As a result, the holder on the left side and the right side of the guide device can be attached, so that, for example, in cable pull devices with two guide devices, such as two-rail window, only one single holder for all installation cases needs to be used. The holder can therefore be manufactured as a common part and is suitable for all installation situations. By this measure, the entire cable pulling device is particularly cost feasible.

According to a preferred embodiment of the invention, it is provided that the at least one rotation is formed by at least one outer peripheral portion of the holder. Thus, the rotation is particularly easy to implement, since the outer peripheral portion of the holder is easily accessible from the outside, so that the passing with the outer peripheral portion in operative position counter surface is easy to align in their position.

The outer peripheral section should preferably come into operative position with a mating surface arranged on the section of the guide device. As a result, the rotation can be realized in a particularly simple manner, since for the production of the Anti-twist protection additional components are not necessary.

Particularly easy twisting is feasible if, according to a preferred embodiment of the invention, the counter surface is formed on a reinforcing member or reinforcing portion. As a result, an already another function performing element of the guide device is used to form the anti-rotation device for the holder. As a result, the rotation prevention manufacturing technology is particularly easy to implement, since with respect to the anti-rotation forming counter surface additional components are not necessary.

Preferably, the reinforcing part or the reinforcing section should project from the section in the direction of the axis of rotation. In this way, a large counter-surface which can be used for preventing rotation can be realized, and at the same time the reinforcing element has a high stiffening or reinforcing effect with respect to the section connected therewith.

Additionally or alternatively, it is provided according to a further embodiment of the invention that the at least one rotation is formed by at least one inner peripheral portion of the holder. As a result, an anti-rotation device located inside the holder can be realized.

For this purpose, the counter surface of the anti-twist device which enters the operative position with the inner circumference of the holder should preferably be arranged on the connecting means. By this measure, the rotation can be realized without the use of additional components by recourse is made by the connecting means to a present anyway in the guide device component. The rotation is therefore inexpensive to realize even in this embodiment.

According to one embodiment of the invention, it is provided that the inner peripheral portion is arranged on a passage of the holder for receiving the connecting means. This measure also aims to use already existing functional parts or functional elements on the guide device in order to realize by multiple function of these elements, the rotation of the holder in a simple and cost-effective manner.

It is advisable that the counter surface for the rotation is formed on the outer periphery of the connecting means. In this way, the rotation can be formed in a particularly simple manner by namely the connecting means and provided for the connecting means passage of the holder having mutually corresponding peripheral portions through which the positive rotation is formed.

Preferably, the connecting means should be held against rotation on the portion of the guide device in order to realize a positive rotation of the holder relative to the portion of the guide device without additional functional parts.

Preferably, the outer circumference of the connecting means has a profile which at least partially corresponds with the profile formed by the inner peripheral portions of the holder. For example, a polygonal profile, for example as a four, six or octagonal profile, may be formed on the connecting means and the corresponding profile may have a corresponding polygonal profile on the inner circumference of the passage. Also, for example, profiles in the form of projections and corresponding grooves, polygons or the like. Non-circular profiles or cross-sections are conceivable, by which in the active position of the profiles to each other a positive rotation is formed.

It is advisable that the connecting means for securing a deflection means for the cable at the portion of the guide device is used. As a result, few components have a high degree of integrity of various functions, namely by the connecting means both the deflection of the cable and the holder for the outer cable of the cable is held and connected to the section or guide portion of the guide device. Preferably, the holder should be between deflection and section.

Furthermore, the invention relates to a cable pulling device, in particular cable window lifter or cable pulley wiper, with at least one guide device according to the invention.
