EP1229198B1 - Cable-operated window lifter for sliding a window pane with a connector and a lockable slider element - Google Patents

Description

The invention relates to a cable winch for moving a window pane on a vehicle, for example a motor vehicle, with at least one guide section, on which a driver is slidably guided via an insertable sliding element having a slider contour, wherein the driver is connected to the cable pull and the window pane is connected and the sliding element has latching means which cooperate with counter-locking means on the driver for latching connection of sliding element and driver, and in that the driver has an elongated recess for insertion of the sliding element, in which recess the sliding element along the longitudinal direction of the recess can be inserted and to bring about the latching connection is recorded with the driver.

Such a cable window is already out of the US 46 33 613 known. The window regulator comprises an elongate plate which is fixed to the door and carries at least one oblique guide rail. At least one slider is slidably guided on the guide rail. A carrier is attached to the windowpane and carries the slider so that the movement of the slider along the guide rail results in a corresponding displacement of the windowpane. Guides allow pivoting of the window during movement. A flexible wire is connected to an area of the carrier Window pane connected and movable via a drive unit within the door. The movement of the wire is transferred to the carrier and thus to the windowpane.

The FR 277 82 00 discloses a cable window with a driver, which is connected to the cable and the window pane. At the driver side a sliding contour is arranged, which is guided displaceably on the rail of the window regulator. Sliding element and driver can be locked together via latching means. For this purpose, a pin-like projection is provided laterally on the driver, which dips into a receptacle on the sliding element in the latching position. In the locked state sliding element and driver are arranged side by side adjacent to each other. This device not only builds large volume, but is very solid in terms of connecting or latching perform, since the lever forces occurring due to the laterally adjacent arrangement of the sliding element and driver must be absorbed during operation of the window.

Another cable pull window is for example from the DE 37 27 153 A1 known, wherein the window to be moved is guided on at least one guide rail. The window pane is held on at least one driver, which in turn slides on the guide rail or other guide section. At the at least one driver engages the cable of the cable winch, which is moved by a cable drum via a crank or an electric motor drive and depending on the direction of rotation raises or lowers the window.

The drivers for such windows of motor vehicles, for example, consist of zinc or aluminum die-cast components with a plastic insert whose slide contour corresponds to the contour of the respective guide rail. As a slider contour, for example, quadrant profiles, hook-shaped extensions or similar profilings are used.

A disadvantage of the known drivers are the assembly of the insert and the tight tolerances, in particular the outer contour, which are to be observed for the plastic insert. Furthermore, it also proves to be disadvantageous that the zinc die cast components for different slide contours, as used for example in different motor vehicle manufacturers, are themselves also designed differently.

In contrast, the invention has the object, a cable winch with the features mentioned in such a way that the assembly and the production are simplified, the window easily and without much effort to different slide contours of the guide sections or guide rails is adaptable and compact and easy to install is trained.

This object is achieved according to the invention in the cable pull window with the features mentioned in the main, characterized in that the longitudinal direction of the recess is aligned substantially transversely to the direction of displacement of the driver along the guide portions.

Due to this measure, the sliding element is preferably releasably latched to the driver, wherein the driver may be formed as a standardized component, for example, and the adaptation to the respective slide contour by latching the respective sliding element takes place with trained trained Gleiterkontur. Also, this cable winch is easy to install and easy to manufacture, since only the preferably made of plastic or other elastic material sliding element of the individual slider contour of the guide portion to train accordingly and is inserted by simply locking in the uniformly shaped driver. In this case, the longitudinal direction of the recess is aligned substantially transversely or, according to an advantageous embodiment, substantially at right angles to the displacement direction of the drivers along the guide sections. As a result of this measure, any forces acting on the sliding element in the method of the driver on the guide sections are absorbed by the inner walls, for example the recess of the carrier which receives the sliding element, wherein the latching and counter-latching means do not stress the connection of the driver and sliding element become. This embodiment further has the advantage that the locking and counter-locking means need not be too strong in terms of dimensions or the detent force, so that on the one hand achieved a material savings and on the other hand, the assembly of the sliding element in the driver due to the very low forces to be relieved is facilitated.

According to a first advantageous embodiment of the invention, the driver has a recess for receiving the sliding element, wherein the recess is preferably provided with guide means, in which the sliding element preferably with corresponding counter-guide means in the longitudinal direction of the recess displaceable in the latching, clipped, in particular releasable connection can be transferred is. An unlatching of the connection can be accomplished, for example, by means of a tool, such as a screwdriver or the like, with which the locking means of the sliding element are released from the counter-locking means on the driver. Under locking means should be understood in the context of the present application any detent, clip or other positive connection between the driver and slider.

Furthermore, it has proven to be advantageous that the sliding element has a counter-stop, which abuts a stop on the driver in the locking position, so that it is ensured for a defined positioning of the sliding element in the locking position on the driver.

According to another preferred embodiment of the invention, the stop on the driver in the detent position in a pocket, recess or the like of the sliding element, in particular taken up substantially flush with the outer contour of the sliding element. Also, due to this measure, care is taken that only made of plastic sections of the slide contour come into contact with the guide sections.

According to an advantageous structural embodiment of the invention, the sliding element as a latching means on a latching nose, which comes in the detent position on a wall, an abutment, a recess or the like of the driver to the plant.

To facilitate the insertion of the sliding element in the recess of the driver, the guide means or the corresponding counter guide means are formed as guide webs or guide grooves, so that is provided for a safe axial displacement guide of the sliding element in the recess of the driver in the direction of the longitudinal axis or longitudinal extension of the recess.

It has proven to be advantageous, in particular with regard to the assembly, that at least some of the guide means or counter guide means are dimensioned differently. For example, a guide web and the corresponding guide groove in the height or depth can be made larger than the remaining guide or guide webs, so that the slider can be connected only in a single orientation or arrangement with the driver or inserted into the recess of the driver. Thus, a faulty mounting of the sliding element on the driver is reliably counteracted.

Of particular advantage, the sliding element is formed substantially in the manner of a U with two legs, on which the locking means and / or and the sliding contour are arranged

It is particularly advantageous if, at the free end of the one leg, an angling is formed as a cover of the guide section with respect to the adjacent wall of the driver. This ensures that the guide sections do not come into contact with the also made of metal driver. Due to this U-shaped design of the existing plastic or other elastic material sliding element, the required bias for generating the latching force or the force to build the positive connection is generated.

Other objects, advantages, features and applications of the present invention will become apparent from the following description of two embodiments with reference to the drawings.
