Description

Window lifter

The invention relates to a window lifting device, in particular for a motor vehicle door, according to the preamble of claim 1. An¬.

In modern motor vehicle construction, so-called frameless doors are nowadays used in many places, in which a side pane, in the closed state and with the side door closed, lies directly against a seal of a vehicle body. In contrast to a door with frame, in which the side window is guided in the frame and surrounded by this and the seal between the frame and the body takes place, in the frameless door, the side window in the closed state and with the vehicle door closed exactly to the seal of Vehicle body in order to ensure the Dich¬ tw effect reliably.

In particular, in the case of small vehicles, a window lifting device of a respective side door often has only one guide rail on which a driver, which carries a side window arranged on it, is guided forcibly. In monorail window lifting devices, however, there is often the problem that the disc can rotate in its disc plane upon reaching an end stop, ie with the side disc closed, and thereby an inexact or non-repeatable position of the disk is required, which in the case of a frameless door can lead to a non-repeatable edge contour at the transition to the shell seal and thus to leaks.

From DE 198 19 953 Al an adjustable driver for connecting a window to a window of a motor vehicle door is known, wherein the driver is adjustably mounted on at least one guide rail and is associated with this of the motor vehicle door. The driver consists essentially of a base body and a Aufnah¬ mekörper, wherein the base body is guided on the guide rail of the window regulator and the window pane is clamped on Aufnahme¬ body. In order to be able to slightly bias the window pane in the direction of the shell seal, the receiving body is pivotable relative to the base body and an articulated connection is provided between the two. The be¬ known adjustable driver thus allows an at least slight bias of the window in the direction of Roh¬ baudichtung. However, a rotation of the window pane or of the driver in the pane plane can not be reliably prevented when the end position of the driver is reached, that is to say when the side window is closed.

From DE 39 30 106 C2 a cable window lifter for Kraft¬ vehicles with at least one on a guide rail positively slidably guided driver is known. The driver is connected to a drive cable and two holding plates which clamp the window pane between them by means of a clamping bolt, which are displaceable relative to the driver laterally and essentially perpendicular to the direction of displacement of the window pane by a predeterminable compensation length in the vehicle longitudinal direction. In addition, a centering device is provided which holds the holding plates in one Middle position of the predetermined compensation length before the final Klernmung the window between the Halte¬ plates positioned by tightening the Kleminbolzens. A rotation obstruction of the disk in the closed state, however, can not be achieved by this.

From the. DE 1 _. 99 56 756 C2 an adjustable driver for a window opener of a frameless vehicle door is known which has a main body connected to the window regulator mechanism and a coupling body connected to the window pane. The coupling body can be fixed with respect to its position with respect to the body at this and displaceable by means of an adjustment device in the direction of travel of the vehicle on the base body. The adjusting device has at least one toothed transmission part and can be coupled with a tool for displacing the coupling body with respect to the base body.

From DE 102 43 496 Al a device for connecting side windows of a motor vehicle with a zugeordne¬ th window regulator is known. The device has an adjusting and clamping device with a section, which cooperates with a guide such that the relative displacement of holding part to power windows by adjusting the section is possible, and which for making the clamping an¬ closing between the holding part and the window clamped is. The relative adjustment of the disk for adjusting its position with respect to the window regulator can be actuated in one and the same direction as well as the subsequent tensioning for fixing the clamping connection. By means of said device, however, a rotation of the window pane in its slice plane when reaching the closed state can not be reliably prevented. The present invention is concerned with the problem for a window lifting device of the type mentioned above to provide an improved embodiment, which allows in particular for a frameless door an exact and repeatable La¬ ge of the disc in the closed state.

According to the invention, this problem is solved by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.

The invention is based on the general idea, in a window lifting device which comprises at least one window lift, a drive coupled therewith driver with angeord¬ Neter disc and a guide rail, to arrange a stop on the driver and / or on the disc, which with the window closed so with a backlash arranged on the guide rail and / or on the vehicle door and designed to be complementary thereto, that ei¬ ne rotation of the disc is excluded in its disc plane.

The stop according to the invention, which cooperates with the counter stop formed complementary thereto, thus enables an exact positioning of the window pane, which is repeatable with respect to its position, in the closed state. This is especially important for frameless doors, since in this case the pane rests directly against a shell seal of the body and an inexact or non-repeatable position of the pane in the closed state can lead to leaks. Of particular importance is the arrangement of the stop or the counter-stop in Einschienenfensterhe- bern, in which only one driver is mounted on only one guide rail adjustable and thereby particularly susceptible to rotational movements of the disc in her

Disk plane is. In general, however, the invention is also applicable to multi-rail window lift in the same way bar.

Suitably, the stop and the counter-stop are designed such that they engage in one another in the manner of a Ma¬ le-female connection with the window closed. Such Male-Female connection ensures a positional fixation of the disc orthogonal to the adjustment of the same and in the disc plane, whereby a rotation of the disc in the disc plane can be excluded. In general, the male-female connection can be designed in such a way that, in particular, the male part has chamfered edges and thus makes possible a facilitated connection.

Suitably, the stop and / or the counter-stop is / are made of metal and / or of plastic. In particular, the training of plastic makes it possible to inexpensively produce the stop and the counter-stop, for example, as an injection molded part in large quantities. In addition, the lower weight of the plastic parts contributes to the fact that the total energy consumption of the vehicle increases only insignificantly.

According to a preferred embodiment of the solution according to the invention, the stop and the counter stop are arranged at a distance from the guide rail transversely to the guide direction. In this case, the farther the distance of the stop and the counter-stop is selected transversely to the guide direction of the guide rail, the greater is the lever of the stop or the counter-stop counteracting a rotational movement of the window. The greater, in turn, the lower the lifting effect, the lower the obstruction of rotation Disc necessary force which must act on the stop or counter stop.

In a further advantageous embodiment of the invention, both sides of the guide rail and in the transverse direction spaced therefrom each a stop and a counter-stop are arranged. In contrast to a only one-sided arrangement of the stop or the counter-stop can be effectively un¬ terbunden in a sche¬ both sides of the guide rail and transversely spaced therefrom arrangement of a rotation of the disc in its disk plane in the counterclockwise and. In this way, a particularly repeatable and thus exact movement or position of the window in the closed state can be achieved, whereby a particularly reliable sealing between the pane and the shell seal on the bodywork can be achieved.

Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination indicated, but also in other combinations or alone, without departing from the scope of the present invention.

Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following Be¬ description, wherein like reference numerals refer to identical or functionally identical or similar components.

Show, in each case schematically, 1 shows a window lifting device according to the invention with a stop,

2 shows a stop and a counter stop in the form of a male-female connection.

According to FIG. 1, a window-lifting device 1 according to the invention comprises at least one window lifter (not shown), a drive-coupled driver 2 and a guide rail 3, on which the driver 2 is forcibly guided in the opening or closing direction 5 of a window 4. In this case, the window lifter causes the adjustment of the driver 2 along the guide rail 3 and thus the opening or closing movement of the window 4 via an adjustment member (also not shown). The window lifting device 1 can be arranged, for example, in a motor vehicle door, which also acts as frameless vehicle door is formed. In general, the window pane 4 is fastened to the driver 2.

In order to ensure a reliable seal between the disc 4 and a body-side seal, in particular in the case of smaller discs, in which a so-called single-rail window lifter with only one guide rail 3 and one driver 2 is provided, it is necessary that the disc 4 in its closed position assumes an exact and repeatable position both in the closing direction 5 and orthogonally thereto. To bring about such a required exact and repeatable position of the disk 4, it is provided according to the invention to arrange a stop 6 on the driver 2 and / or on the disk 4. This interacts with a closed window 4 with a arranged on the guide rail and / or on the vehicle door and complementary thereto counter-stop 7 together, that a rotation of the disc 4 in its disc plane aus¬ closed.

In principle, the stop 6 and the counter-stop 7 can be designed so that they engage in the closed window 4 in the manner of a male-female connection with each other (see Fig. 2).

According to FIG. 1, a stop 6 and a counter stop 7 are arranged on both sides of the guide rail 3 and spaced transversely therefrom. Due to their distance from the longitudinal axis of the guide rail 3, a Dreh¬ movement favorable lever arm can be realized. An arrangement of the stop 6 and the counter stop 7 selected on both sides of the guide rail 3 moreover has the advantage that a rotational movement of the disc 4 in its disc plane can be effectively prevented both clockwise and anticlockwise. In general, however, it is also conceivable that the stop 6 and the counter-stop 7 are arranged on one side of the guide rail 3 transversely to the guide rail 3 at a distance from the longitudinal axis thereof.

In addition, it is conceivable that at least one stop 6 is arranged in the transverse direction far from the longitudinal axis of the guide rail 3 spaced on the disc 4 and cooperates geschlos¬ senem state with a arranged on the vehicle door Ge genanschlag 7.

An obstruction of the rotational movement can also be achieved by the stop 6 or the counter-stop 7 on the driver 2 and the counter-stop 7 or stop 6 complementary thereto being arranged on the guide rail 3. The hitherto described applies both to single-rail window lifting devices and to multi-rail window lifting devices, so that these too should be included in the invention.

In general, the stop 6 and / or the counter-stop 7 may be made of metal and / or of plastic, wherein in particular a plastic embodiment allows cost-effective production in large quantities as an injection-molded part. In addition, 'plastic has a low weight, so that the additionally by the stop 6 and counter stop 7 auf¬ passing weight is marginal. Also conceivable is a design made of metal, for example as a stamped part or a combination of several materials.

Since the rotational movement of the disc 4 preferably occurs when the window is almost closed or completely closed, the counter-abutment 7 is arranged on an upper end region of the guide rail 3 or a corresponding region of the vehicle door in the installed state.

According to FIG. 2, the counter-abutment 7 (femoral part) has chamfered edges 8 in the entry area, which facilitates insertion of the counter-abutment 6 and thereby improves the functional reliability. In addition, an engagement pin 9 of the An¬ impact 6 on a rounded tip, which also tert the connection between the stop 6 and counter stop 7. Due to the complementary design of the counter-stop 7 with respect to the stop 6, the rotational tendency of the disk 4 can be prevented or reduced in a particularly effective manner. The embodiment of the male-female connection shown in FIG. 2 is intended to be purely exemplary, so that other embodiments of the invention should be um¬ closed. In general, the Fensterhebeein¬ device 1 according to the invention ensures the exact and repeatable position of the disc 4 and thus an exact and repeatable edge contour at the transition transition of the disc 4 to a shell seal, whereby a zu¬ reliable sealing of the vehicle can be ensured.

In summary, the essential features of the solution according to the invention can be characterized as follows:

The invention provides for a window lifting device 1, which comprises at least one window lifter, a driver 2 coupled thereto with a disk 4 fastened therein and a guide rail 3, to arrange on the driver 2 and / or on the disk 4 a stop 6 which when ge closed window 4 so cooperates with a arranged on the guide rail 3 and / or on the vehicle door and complementary thereto counter-stop 7 that a rotation of the disc 4 in its disc plane is effectively unter¬ prevented.

In this way, a particularly accurate and repeatable position of the disc 4 can be achieved in the closed state, wo¬ can be ensured by a reliable seal between the disc 4 and a body-side shell seal.
