Description

The invention relates to a driver for connecting a window pane to a window lifter from holding legs on either side of the lower edge of the window pane assigned. At least one of these holding legs has a recess, into which a window bolt can engage to lock the window. At least the upper part of at least one holding leg is resilient and has one Introductory area.

DE 44 23 440 A1 describes a driver for fastening a window pane Motor vehicle known on the guide rails of a window regulator. This consists of Holding legs arranged on both sides of the lower area of the window pane are. At least one of these holding legs has a recess into which a connecting element can intervene to lock the window pane. At least an upper part at least one holding leg is resilient and carries one in the direction Lower edge of the washer directed insertion chamfer.

The connecting element for locking the window pane is already in place before assembly connected to the window pane. The connecting elements are in through holes Bolts mounted on the washer, elements glued to the washers or out of the washer molded elements used.

For assembly, the connecting element is inserted into the gap between the holding legs and engages there in their recesses. This will change the location of the window pane fixed.

To compensate for tolerances in the parallelism of the guide rails or adjustments To be able to make the recesses are in one embodiment of the invention as horizontally oriented elongated hole guides. So can the storage of a connecting element firmly in the carrier and the storage of the other connecting element in this slot guide (system floating bearing / fixed bearing).

Despite these measures, the device is not able to compensate for the tolerances, between the window pane and the seal when moving the window pane may occur. The reason for this is that the window pane through the fixed bearing in their position in relation to the motor vehicle door, that is to say for guiding the pane in the motor vehicle door, is set. Unfavorable tolerance positions can lead to high frictional forces in the guides or come in the seals of the window pane in the vehicle door.

This solution has the further disadvantage that in the manufacture of motor vehicle doors for any angular position between the direction of travel of the driver and the lower edge of the Window pane a special, type-appropriate driver must be provided.

The object of the invention is to develop a driver that for different Angular positions between the direction of travel of the driver and the lower edge the window pane can be used and / or to compensate for the position of the window pane in the direction of travel (x direction).

According to the invention, this object is achieved by Features of the 1st and 6th claim solved.

According to the solution variant according to claim 1, one of the Holding leg assigned a holding area, which is called horizontal Slot guide is formed, and the other Holding leg is assigned a fastening area which is horizontally spring loaded.

This variant of the solution has the advantage that both Compensation of the tolerances regarding the parallelism of the both guide rails and the parallelism between the pane guide on the B-pillar and the one assigned to it Guide rail can be reached.

Since on a driver both the function of leading in vertical direction (z direction) as well as the function of the Feders united in the horizontal direction (x-direction) is the construction of the attachment of the disc both drivers of double rope window lifters the same. In order to the drivers can be constructed identically and it is possible to use them for single-strand window regulators.

According to the solution variant according to claim 6 is in the range a contour is formed on the lower edge of the window pane, their parallel to the plane of the window pane Cross-section is formed as a circular section surface, the height of the circular section depending on the angular positions to be covered between the driver and the The edge of the pane is fixed and the contour on a Driver arranged support surface loads and the The width of the support surface is such that the support point with maximum tolerance deviations in horizontal Direction is still on this support surface.

This solution has the advantage that the invention Driver for this solution for different angular positions of the driver is suitable for the window pane. simultaneously is also a way to compensate for movement at right angles to the direction of travel of the window pane or Direction of force possible in the window pane. This makes it possible to manufacture a universal driver which is suitable for a variety of applications.

Another advantage is that there is no motion component the actuating force parallel to the lower edge of the Window pane (in pane level) occurs.

The embodiment of Figure 1 shows a driver 2, the two holding legs 21, 22 is equipped. In the gap 25 between the holding legs 21, 22 is the window pane 1 is held in the region of its lower edge 11. In the window 1 is as Connecting element introduced a disc bolt 3, which by the holding legs 21, 22nd is held.

In Figure 2, the holding legs 21, 22 are shown in the cut state, the Section lies in the plane of the window pane 1. It can be seen that both holding legs have at their upper part an insertion chamfer 23, 24 which the disc bolt 3 in should be in its installation position. Both the holding leg 21 and the holding leg 22 are symmetrical. In addition, the two holding legs differ 21, 22 in their structure, however, significantly different.

Part of the holding leg 21 is a fastening area with a bolt receptacle 26, which receives the disc pin 3 (see Figure 1). The pin receptacle 26 is in the x direction (i.e. in the direction of travel) spring-loaded. This is achieved by the bolt receptacle 26 has a V-shaped insertion area, between the V-shaped Entry area and the base body 29 of the driver 2, a spring-elastic web 28.1 is formed. The shape of the bolt receptacle 26 is not limited to the V shape. For example, a bolt receptacle 26 in the form of an "M" is also possible (see see Figures 13 to 15). The V-shaped insertion area protrudes on both sides Leg (28.2) with the base body (29 ') in connection, both the V-shaped insertion area and / or the side legs (28.2) are designed to be resilient.

The holding leg 22 has a holding area in the form of an area extending in the x direction Elongated hole 27 (see Figure 2), which receives the disc bolt in its installed position.

When inserting the window pane 1, the pane bolt 3 passes through the insertion chamfers 23, 24 in the installation position. The slot 27 of the holding leg 22 allows a shift in the x direction, but the force components acting in the vertical direction (z direction) fully absorb. Therefore, the holding leg 22 is directly on that of the guide rail facing side arranged so that the withdrawal forces are transmitted safely can.

The bolt receptacle 26 of the holding leg 21 takes over the securing of the position in the x direction. Although this determines the position of the disc bolt 3, can the spring action in the x direction can be safely compensated for installation tolerances.

FIGS. 3a, 3b and 3c show one possibility of the advantages of the invention Driver with regard to the tolerance compensation when installing the window pane 1 exploit. FIG. 3a shows the position of the window pane 1 relative to the seal 4 Vehicle door, not shown, before installation. The installation tolerances are determined so that the window pane 1 opposite those located on the B-pillar of the vehicle Sealing section 41 has a distance or just touches it, so that the Window pane 1 can be installed stress-free.

3b shows the window pane 1 connected to the driver 2. It is to recognize that there is a distance between the window pane 1 and the sealing section 4 Δx is present. When moving the window pane up (see Figure 3c) through the oblique sealing section 42, the window pane 1 into the sealing section 41 pressed and compensated for any distance there.

Another installation concept is shown in FIGS. 4a to 4c. Here are the installation tolerances chosen so that the window pane with a bias to the sealing portion 41 is installed on the B-pillar (see Figure 4b), so that the window pane 1 at their upward movement always has contact with the sealing section 41. The tolerances must be selected so that the edge of the window pane is at the maximum right tolerance position 1 just lies stress-free on the sealing section 41.

5, 6 and 7 show a driver 5 which is used for cable or tube window lifters can be used and offers the possibility of this for different positions to be able to insert to the lower edge 11 of the window pane. For better clarity is in the view shown in Figure 6 front bracket 53.1 and the window 1 has been omitted.

The driver 5 consists essentially of a driver base body 54, which with Bracket 53.1, 53.2 is provided which the holding legs described in Figures 1 and 2 21, 22 correspond. The brackets 53.1, 53.2 have an insertion chamfer 531 (see see also FIG. 6) for the introduction of a disk bolt 62.

There is a window pane between the carrier base body 54 and the brackets 53.1, 53.2 1 associated connector 6 attached. In Figure 6 is the connecting part 6 more clearly recognizable.

As can be seen in FIG. 6, the connecting part 6 consists of a base body 61, which is arranged on both sides of the window pane 1 and glued to it. On the main body 61 circular disk bolts 62 are formed on both sides. The lower part of the body 61 carries a contour 63 which has the shape of a circular section surface.

From FIG. 7 the geometrical relationships that can be seen in the configuration can be seen of driver 5 are to be observed. The contour 63 bears in the support point A on a support surface 51, which is arranged on the driver base body 54. The width b of the support surface 51 must be dimensioned so that at maximum displacement of the support point A in the x direction this is still on the support surface 51.

It is necessary that the radius R1 of the connecting element 61 and the radius R2 of the Contour 63 has the same center point M. The reason for this is that the Distance between the upper contact point A1 of the disk bolt 62 on the bracket 53.1; 53.2 and the support point A on the support surface 51 at any angular position between the Driver 5 and the window pane 1 must always be the same.

In addition to the support point A (in the x direction), free spaces are provided that are intended to secure that at different angular positions of the connecting part 6 to the support surface 51 the Not the lower edge of the connecting part 61 and / or the lower edge 11 of the window pane 1 sits on the carrier base 54. These free spaces are created by the fact that the areas adjacent to the support surface have a sloping contour 55.1; 55.2 have.

The connecting part 6 is between the brackets 53.1, 53.1 of the driver 5 and the support surface 51 arranged without play.

The invention is not limited to the one described above Embodiment. In particular the design of the connecting part 6 is not to be shown and described Bound shape. It is also possible, for example, the Contour 63 directly on the lower edge 11 of the window pane 1 to form, to work the contour 63 out of this or glue the contour 63. The disc bolt can then arranged in a pane hole in the window pane 1 are or are also molded.

The design of the support surface 51 does not have to be flat Area to be executed. It is also possible to use the support surface 51 to be designed so that they are trough-like is.

Another advantageous embodiment is shown in FIGS of the connecting element shown. Here is the connector 6 'executed in two parts. The connection between the individual parts 6.1 ', 6.2' take place via form-fitting Elements. In this case it is a square tooth 7.1, 7.2. The contour 63 'is in the area of this rectangular toothing formed.

The two individual parts 6.1 ', 6.2' are on both sides of the Window pane 1 glued to this. When merging the individual parts 6.1 ', 6.2' guarantees the rectangular toothing 7.1, 7.2 their exact supply. Tolerances regarding the thickness of the window pane 1 are compensated so that the entire surface of the adhesive surfaces can be achieved.

Using the figures 10 to 12 are some installation situations of the driver 5 according to the invention shown. For better For clarity, the driver 5 is only schematic here shown. As can be seen in the figures, glides the driver 5 on guide rails 8, which in the drawings are indicated by a dashed line. From the figures 10 and 11 can be seen that the angle of the guide rail 8 to the carrier 5 different depending on the installation situation Can assume values without the function of the driver 5 is impaired. The critical angle positions are determined by the design of the driver specified in the area of the free spaces 52.1, 52.2.

FIG. 12 shows a case in which the position of the guide rails 8 with regard to the predetermined parallelism and / or differ in terms of the distance from each other. It can be seen that a displacement of the support point A on the support surface 51st is possible by an amount a, so that tolerances in the x direction are compensated for can. The extent of the possible displacement depends on the width of the support surface 51 and the geometry of the contour 63.

A further embodiment of the invention can be seen from FIGS. 13 to 15. Here are the features of the solution described for Figures 1 and 2 with the features of the Figures 5 to 7 solution combined. The holding legs 21 '; 22 'are like that formed that a holding leg 21 'as a horizontally resilient fastening area Bolt receptacle 26 'is assigned, which is a position of the disk bolt 62' in the x direction secures, but against movement of the disk bolt 62 'or the base body 61' the spring force of the pin receptacle 26 'allows. The bracket 53.2 secures the position of the disc bolt 62 'in the z direction.

The other holding leg 22 'is assigned a holding area which is defined by the bracket 53.1' is realized and holds the disk pin 62 'in the z direction. The contour is 63 " on the support surface 51 'as described above.

This driver is able to compensate both in the x direction and to realize different positions of the driver to the window.
