Description

The invention relates to a window, in particular motor vehicle window lifter, with a driver on which a window pane can be fixed, and which - in particular by means of a cable - along a displacement path is movable. Furthermore, the invention relates to a door, in particular motor vehicle door and a motor vehicle with such a window.

The FR 2 830 894 A1 describes a window with a driver, which can be moved along a displacement path or a rail. A holding element is used in a holding position of the fixation of the driver on the rail. The holding element is designed as a spring and can be transferred from a rest position into the said holding position.

From the DE 10 2006 017 424 A1 goes out a spring elements exhibiting, designed as a support plate holding element. The spring elements are designed as elastic tabs and can fix an end stop for a displaceable driver of a window regulator assembly.

Out WO 2005/095745 A1 a power window assembly is known. In this document means for positioning and fixing of the driver are described, which serve to facilitate the installation of a window pane, in particular in so-called windowless power window systems. In such guidance window systems, although the window glass pane edge is guided in a vehicle-side guide, the driver moves, however, unguided when lifting and lowering the window. Due to the lack of a guide for the driver, however, this can tilt during assembly of the window by the torques occurring. To solve this problem, means for positioning and fixing the driver with two support blocks are described in the above-mentioned document, which are integrally attached to a wall portion of the door and serve as lower stops for the driver. The disadvantage here is that these support blocks are formed on the wall part. It follows, however, that the mounting position must be at the lower end of the displacement of the window, since the driver can not drive over the support blocks away.

A solution to this problem will be found in DE 10 2005 061 009 B3 which describes a window regulator assembly having a driver, a door inner panel and positioning means for positioning the driver in a mounting position. In this case, the positioning means can assume a first position, which corresponds to the mounting position for the driver and the window pane, and a second position, in which the positioning means release a movement of the driver for opening and closing the mounted window pane. In addition, an elastic element may be provided on the positioning means, which returns the positioning means after mounting the window pane in the second position.

A disadvantage of the positioning means described therein is that they are structurally very complex and in particular require a hinge in order to take the two positions can. However, this also involves higher manufacturing costs and a high weight, with the latter in particular having a particularly disadvantageous effect on use in motor vehicle doors.

The present invention is therefore based on the object to improve a window lift with the features mentioned in the sense that the disadvantages described above are avoided.

This object is achieved by a window according to claim 1 and a door according to claim 17. Advantageous embodiments of the invention are the subject of the dependent claims.

According to the invention it has been recognized that in a window of the type mentioned only a spring for safe and reliable fixing of the driver during assembly of the window is sufficient, the spring against its spring force from a rest position in which the spring moving the driver along the displacement is not influenced out, can be converted into a holding position in which the driver is fixed in a driver-Festlegestellung with the spring, wherein the spring located in the holding position at least partially surrounds the driver located in the driver-determining position.

Clarification should be noted that under the displacement in the context of the present application, the area is understood, which is covered by the driver on which a window is already properly mounted when raising and lowering the window - that is, during operation of the window.

Such a spring offers several advantages over the known from the prior art positioning means. On the one hand, no complicated and fault-prone hinges are necessary in order to be able to transfer the spring from the rest position to the holding position. On the other hand, a spring works very reliably, since it can only consist of a few - especially even a single component. This also results in advantageous that the spring cost and space and can be produced weight-saving. A gripping can fix the driver, in particular during assembly of the window, for example against displacement along the displacement of the window regulator.

In a particular embodiment, the spring is designed as a leaf spring and / or spring clip.

In a particular embodiment, a determination of the driver is particularly effective and advantageous that the spring located in the holding position is applied to the driver located in the driver-fixing position with its spring force. Thus, the spring force is not only used to return the spring from the holding position to the rest position, but also to set the driver.

In addition, according to an advantageous embodiment of the window lifter can be provided that in particular in the holding position, the spring is substantially S-shaped and / or that the projection of the spring in the holding position on a plane parallel to the direction of the spring force substantially S- is shaped. This ensures that the spring in the holding position, the driver in the driver-Festlegestellung by the S-shaped configuration can embrace in a bend of the S-shape, so that in particular the spring force can act on the driver.

According to a further advantageous embodiment of the invention, a free end of the spring located in the holding position engages in a recess and / or groove of the driver located in the driver-determining position. The other end of the spring can be fixed to a support or to a door, in particular the motor vehicle door. By engaging in the recess and / or groove, a displacement of the driver in the driver-Festlegestellung against the spring in the holding position is additionally prevented in a particular embodiment.

According to another embodiment of the window, a free end of the spring located in the holding position in a recess and / or groove of the carrier or the door, in particular motor vehicle door, engage, wherein the other end of the spring is fixed to the driver.

According to a further advantageous embodiment of the window regulator according to the invention it is provided that an aligned perpendicular to the direction of the spring force and / or perpendicular to the displacement end of the located in the driver-determining carrier on a part of the spring in the holding position - especially at a middle Part of the spring - abuts. In that regard, the part of the spring acts on the driver as a stop. This part of the spring may, for example, be the middle part of an S-shaped bent spring.

Thus, the determination of the driver can be enhanced by the spring, in particular the application of the driver with the spring force of the spring. Alternatively, this end face may also be supported against external forces by a part of the spring located in the holding position, in particular by a central part of the spring, in particular against the forces exerted by screwing on the driver when fastening the window pane.

A particularly stable attachment of the driver is achieved in that the spring in the holding position the driver in the driver-Festlegestellung against a portion of the carrier and / or a portion of the door, in particular motor vehicle door, suppressed. For this purpose, it may be advantageous if the spring on the vehicle door, in particular on a door inner panel, can be fastened or attached. In particular, the spring may be fixed directly to the door and / or be part of the door and / or be formed integrally with the door.

Furthermore, it can be advantageously provided that the spring located in the holding position determines the driver located in the driver-setting position against displacement perpendicular to the displacement and / or sets against displacement perpendicular to the displacement and perpendicular to the spring force. For this purpose, for example, a previously described recess or a groove in the driver, in which engages the spring or which engages around the spring is suitable.

There are in an advantageous embodiment, special additional weight, cost and space advantages, when the spring is formed integrally with the inner door panel and / or is made in one piece with the inner door panel. For example, the spring may be stamped out of the door inner panel as a spring tab, wherein it preferably remains connected to the door inner panel in such a way that the spring tab can be bent elastically out of the door panel plane, at least temporarily.

According to another preferred embodiment of the window lifter is provided that the spring is arranged on a carrier arranged outside the displacement path and / or is formed integrally with a carrier arranged outside the displacement path. Preferably, this carrier also carries other components of the window, such as pulleys or indirectly indirectly the cable used to operate the window regulator. Due to the multiple use of the carrier weight can be saved in addition.

A particularly easy to manufacture and cost-effective embodiment of the window is obtained when the spring is formed as a stamped part and / or that the spring is made together with the support or the door inner panel or the motor vehicle door as a stamped part.

Windows, which result from one of the previously mentioned possible embodiments are - as described above - particularly suitable for such systems in which the window has no guide rails for the driver and / or is designed as a guide windowless.

Hereinafter, an embodiment will be described with reference to the drawings.

1 shows a possible embodiment of a window regulator according to the invention 1 , as used for example in the side door of a motor vehicle for raising and lowering the window pane used. The window regulator 1 has a driver 2 on, on which the window pane can be fixed and which by means of a cable pull 3 along a displacement path C is movable.

In the present embodiment, the driver 2 for fixing the window pane, a cylindrical disc fastening device 7 on, which engages positively in a corresponding hole in the window pane. The cable 3 is right on the driver 2 attached. To lift and lower the window pane are on the driver 2 starting from a drive displacement forces by means of the cable 3 transmit, with the cable 3 Part is guided over pulleys or the like. Such pulleys and other, not shown components, can on the support 6 of the window regulator 1 be set.

In the present embodiment, the window is 1 designed as a guide windowless, ie the window has no guide rails for the driver 2 on. To the aforementioned problems when mounting the window on the unguided driver 2 To avoid, points the window regulator 1 a holding element 4 on. This holding element 4 is in the present embodiment as a stamped part integral with the carrier 6 made and as a spring tongue 4c educated. Alternatively, the retaining element 4 also as a separate component on the carrier 6 be attached. Technically, it is also possible that the retaining element 4 on a motor vehicle door, in particular on a door inner panel, fastened and / or is designed as a part thereof.

The spring tab 4c can by a fitter, for example, with the aid of a screwdriver, from its rest position A1 against the spring force e out into a stop position A2 be transferred, in which the driver 2 in a driver specification B with the holding element 4 So with the spring tab 4c , is fixed. The driver specification B corresponds to the position of the driver 2 in which the window pane on the driver 2 is mounted. Is the spring tab in the holding position A2 That's the driver 2 in the driver specification B fixed. This ensures that the driver 2 can no longer move, in particular can no longer tilt, if during assembly of the windowpane forces and torques on the driver 2 Act.

In particular, this acts in the holding position A2 located holding element 4 in the driver-fixing position B located driver 2 with his spring force. As in 1 shown is the driver 2 particularly efficient acted upon by the spring force, as the driver 2 on a part, in particular on the middle part, which is in the holding position A2 located holding element 4 is applied. This is the driver 2 from the holding element 4 against a part of the carrier 6 pressed.

The carrier 6 is out of the way C of the driver 2 arranged. As the retaining element 4 integral with the carrier 6 is formed, affects the holding element 4 , moving the driver 2 along the displacement path C not when it is in its rest position A1 - as in 4 shown - is.

Will be the driver 2 after completion of the assembly of the window pane upwards, ie in the direction of a closed window position, moves, so the carrier is released 2 after a certain travel from the deadlock between the holding element 4 and the carrier 6 and the holding element 4 automatically returns to its rest position, driven by the spring force A1 back. After that, the driver 2 along its entire displacement path C be moved freely.

How out 2 can be seen, the driver points 2 a rectangular groove 5 on. But there are also other groove profiles and / or recesses, which are not shown here, conceivable. In this groove 5 grab a free end 4a of the holding element 4 when the retaining element 4 in the stop position A2 and the driver 2 in the driver specification B are located. This is the driver 2 in the driver specification B both perpendicular to the spring force as from perpendicular to the displacement C established. In addition, as not shown here, the retaining element 4 the driver 2 also surround at least partially clipped, so that in addition a determination of the driver 2 along the displacement path C is given, which can be solved, for example, by hand after completion of the assembly work.

3 shows the wearer 6 and that in holding position A2 located holding element 4 in a side view. As can be seen from this side view, the retaining element 4 as S-shaped spring tab 4c educated. The spring tab 4c has a free end 4a and another end 4b on that in the carrier 6 merges in one piece. In the shown holding position A2 a gap forms between the free end 4a of the holding element 4 and the carrier 6 in which the driver 2 can be included for determination. This pushes the free end 4a and in particular the middle part of the holding element 4 the driver 2 against a part of the carrier 6 and thus causes the required determination of the driver 2 in the driver specification B ,

4 shows the wearer 6 and at rest A1 located holding element 4 in a side view. In this rest position A1 influences the retaining element 4 the displacement C of the driver 2 Not.

According to a further advantageous embodiment of the window lifter according to the invention, it is provided that an end face of the driver located perpendicular to the direction of the spring force and / or perpendicular to the displacement path of the driver located in the driver-fixing position on a part of the holding element in the holding position - especially at a middle Part of the retaining element - abuts. In that regard, the part of the holding element, on which the driver is applied acts as a stop.
