Abstract

The invention relates to an adjustable carrier for connecting a window pane to a window lift of a motor vehicle door, whereby the carrier is assigned to the motor vehicle door via guiding tracks. The carrier is essentially comprised of a base body and of a holding body. The base body is guided on the guiding tracks of the window lift, and the window pane is clamped in the holding body. The holding body can horizontally sweep in relation to the base body, and a joint connection is provided between the base body and the holding body. According to the invention, adjusting means (511) which can be operated by a tool (510) are provided for changing the position of the holding body (2.5) relative to the base body (1.5). This position is directly or indirectly changed by the actuation of the adjusting means in such a way that the position of the holding body relative to the base body remains unchanged when loosening the fastening the window pane.

Description

Adjustable driver for connecting a window pane to a motor vehicle window regulator

The invention relates to an adjustable driver for connecting a window pane to a motor vehicle window lifter according to the preamble of claim 1.

The driver is assigned to the motor vehicle door via at least one guide rail and essentially consists of a base body and a receiving body, the base body being guided on the guide rail of the window lifter and the window pane being clamped onto the receiving body. The receiving body can be pivoted to the base body, and an articulated connection is provided between the base body and the receiving body.

The invention further relates to a driver, in which a displaceable adjusting means is additionally provided between the base body and the receiving body.

From DE 44 35 008 AI a solution for adjusting a window in the course of assembly is known. The preferably frameless window pane is held inside the door by guide rails. The guide rails can be pivoted about an axis of rotation in the transverse direction of the vehicle, which lies in the upper fastening point of the guide rails. The adjustment is made at the lower end of the guide rail by an adjusting device.

The disadvantage of the solution is that the space in the lower region of the door is limited due to the distance between the pivot point and the location of the adjusting device, so that no large adjustment paths can be realized. In addition, the entire installation space is affected, which means that the adjustment path must be taken into account when designing the entire door.

These disadvantages are avoided in DE-OS 28 43 634. The axis of rotation of the swivel movement lies in the driver. The driver has a spherical segment that corresponds to a corresponding bearing shell. A clamping screw is arranged in the center of the bearing shell and in the ball segment, which engages in the disk hole and interacts with a clamping plate. The adjustment or swiveling takes place by swiveling the bearing shell. The position is fixed by tightening with the clamping screw.

The window pane is thus set freely in the room. This means that one has to gradually approach the correct situation using the "trial and error" method. If the target position is not reached in the current adjustment step, the pane clamping must be released. The previous position is lost and a next adjustment step must be initiated. Due to the setting principle, when the disc is set transversely to the direction of travel, there is also an unwanted vertical shift.

In another known solution, the window pane is attached to a separate part that is articulated to the driver. Between this part and that A vertically displaceable wedge is arranged so that the angular position of this part relative to the driver and thus the position of the window pane in relation to the vehicle body can be changed. The disadvantages mentioned for the previous solution also apply to this solution.

The invention has for its object to provide a simple solution for pivoting the window pane about an axis lying substantially parallel to the direction of travel, by which an exact application of the window pane to an associated sealing contour on the vehicle body is made possible.

According to the invention, this object is achieved by the features of claim 1 and claim 16.

According to a solution variant, setting means for changing the position of the receiving body relative to the base body are provided on the driver, which can be actuated by means of a tool from outside the driver and the window regulator (e.g. by an operator or a robot). These adjusting means act independently of the fastening means with which the window pane is fastened to the receiving body of the driver. The relative position of the receiving body and the base body can therefore be changed directly or indirectly by actuating the adjusting means in such a way that this position is retained even when the window pane is subsequently loosened.

The adjusting means can be arranged so that it acts directly in the direction of the pivoting movement of the receiving body relative to the base body. In another embodiment of the invention, the adjusting means is assigned an adjusting means which is directed in the direction by the adjusting means the articulated connection between the receiving body and the base body can be moved, so that there is an indirect adjustment.

As adjusting means are adjusting screws, threaded spindles, threaded bolts or the like. intended.

Sliding elements, such as sliding wedges, are preferably provided as the adjusting means. The contact surfaces of the sliding wedges with the base body and / or the receiving body can be flat or curved. A preferred solution is a circular arc-shaped cylinder surface with the same radius and the same center point both on the sliding wedge and on the receiving body or base body, since a full-surface contact is achieved in the course of the displacement.

This solution has the advantage that a simple and uncomplicated adjustment is possible. The adjustment is carried out by actuating the adjusting means from the outside, preferably by means of the crash protection strip of the vehicle body.

An angle of rotation on the adjusting means is assigned a precisely defined adjustment path on the upper edge of the window pane, so that the adjustment can be carried out quickly and precisely.

In another basic solution variant, the displaceable part consists of two segments, each segment having a contact zone which is connected to an assigned contact area on the base body and / or on the receiving body, and the tangents at their contact surfaces, lines of contact and / or points of contact from one another have different slopes. Through the variable slope of the tangents, the position of the pivot axis of the window pane can be determined.

This variant of the solution has the advantage that the pivoting movement of the window pane is not bound to the physically trained joint but can be fixed freely in space. The contact zones on the segments and the contact areas on the base body or on the receiving body can be designed in such a way that the window pane can be pivoted about any point in space.

The invention will now be illustrated using exemplary embodiments.

The structure of a driver can be seen from FIG. A base body 1.1, which is guided on a guide rail (not shown here) of a window lifter, is connected in an articulated manner to a receiving body 2.1.

The articulated connection takes place via a cylindrical guide piece 30.1 assigned to the base body 1.1, which corresponds to a guide surface 31.1 machined into the receiving body 2.1.

In this area, a through hole 32 is arranged both in the guide piece 30.1 and a corresponding threaded hole 20 in the receiving body 2.1, in which a clamping screw 120 engages.

A window pane, not shown here, is assigned to the receiving body 2.1. This is supported on disk holders 21.1 and is connected to the receiving body 2.1 via a disk bolt, not shown here, which is guided through the disk bolt bore 22.1. A recess 10.1 is provided in the base body 1.1 in order to ensure the space required for the disk bolt.

In the lower part of the driver, an adjusting screw 50 is arranged, the head of which is attached to the receiving body 2.1. brought receptacle 23 is embedded and which engages in a threaded bore 11 of the base body 1.1.

To adjust the inclination of the window pane, the adjusting screw 50 is rotated and the distance between the base body 1.1 and the receiving body 2.1 is changed in a defined manner. The guide surface 31.1 slides on the guide piece 30.1, so that the receiving body 2.1 is pivoted to the base body 1.1 in the y direction. This movement takes place about a pivot axis 33.1 lying on the x-axis. The pivot axis 33.1 is not fixed, but moves with the movement. This means that the position of the window pane is also slightly shifted on the z-axis.

The clamping screw 120 is used to fix the position of the receiving body 2.1 to the base body 1 and thus to fix the inclination of the window pane.

Another embodiment is described in FIG. Here, the articulated connection between base body 1.2 and receiving body 2.2 is realized via an axis designed as an adapter sleeve 34.1. Bearing tabs 35.1 are formed on the receiving body 2.2 and engage in corresponding openings 13.1 in the base body 1.2. Bearing holes 36.1 in the bearing tabs 35.1 accommodate the clamping sleeve 34.1, which is mounted in holes 14 of the base body 1.2. The receiving body 2.2 can thus be pivoted about the pivot axis 3.2 with respect to the base body 1.2.

The setting is made via a threaded bolt 51, which is on both sides in stepped bolts 52.1; 52.2 intervenes. The stepped bolt 52.1 is mounted in the base body 1.2 and the stepped bolt 52.2 is mounted in the receiving body 2.2, the position of which is determined by plastic clips 53.1; 53.2 is fixed. The disc inclination is set by the rotary movement of the threaded bolt 51. One revolution results in a defined change in the angle of attack of the receiving body 2.2 relative to the base body 1.2.

The position is fixed by a separate screw, not shown here. The pane is attached analogously to the example explained with reference to FIG. 1.

A further embodiment of the invention is shown in FIG. The receptacle body 2.3 is designed here in three parts for the purpose of gentle disk clamping and consists of a receptacle plate 24.1, an insert 25.1 and a holding plate 26.1. The mounting plate 24.1 is connected to the base body 1.3 analogously to the exemplary embodiment described with reference to FIG. 2. The insert 25.1, which surrounds the window pane, adjoins the receiving plate 24.1. The receiving plate 24.1 carries a collar 27 which engages in a disc hole.

Through the mounting plate 24.1, through the insert 25.1 and through the holding plate 26.1, a fastening screw 28.1 provided for the disk clamping engages. The fastening screw spreads the collar 27 and thus fixes the position of the window pane.

The articulated connection between the base body 1.3 and the receiving body 2.3 takes place analogously to the example described with reference to FIG. 2.

A threaded bore 28.2 is provided in the holding plate 26.1 for receiving the fastening screw 28.1, into which the fastening screw 28.1 engages. By turning the fastening screw 28.1, the holding plate 26.1 is against the mounting plate 24.1 pulled and thus clamped the window.

The adjustment of the disc inclination takes place via an adjusting screw 54. One side of the adjusting screw 54 engages in a threaded bore 15 which is made in an extension 16 of the base plate 1.3. The adjusting screw 54.1 has a collar 54.2, which bears against an extension 29 of the receiving plate 24.1 via a rubber buffer 55 and in the assembled state in the area of the holding plate

28.2 protrudes. By turning the adjusting screw 54.1, the collar 54.2 presses against the extension 29, so that the adjustment process can be implemented in this way.

Another embodiment of the invention is shown in FIG. Here, as in the exemplary embodiment according to FIG. 3, the window pane 7 is clamped between a receiving plate 24.2 and a holding plate 26.2 via an insert 25.2. The mounting plate 24.2 is via a bolt

34.3 articulated to the base body 1.4.

A threaded piece 56 is mounted in the center of the base body 1.4 in a threaded bore 17. A threaded spindle 57 leads through the threaded piece 56 and through a bore in the receiving body 2.4. The ends of the threaded spindle 57 are nuts 58.1; 58.2 assigned, the nut having 58.2 left-hand threads and the nut 58.1 having right-hand threads. The threaded spindle 57 has a square 57.1 in the area of the threaded piece 56, which engages in a correspondingly designed contour of the threaded piece 56.

To set the window pane 7, proceed as follows: One of the nuts 58.1; 58.2 is resolved. Then the spindle 57 is rotated. The opposite nut 58.1, 58.2 also rotates. The rotational movement of the spindle 57 is transmitted to the threaded piece 56 via the square 57.1. This engages with the base body 1.4 via a thread. As a result of the rotation of the spindle 57, the threaded piece 56 is displaced on the y-axis relative to the basic body 1.4 and pressed against the receiving body 2.4 so that it is pivoted about the bolt 34.3.

After the adjustment process, the position is fixed by tightening the nuts 58.1 or 58.2.

Another embodiment is shown in FIG. 5. The articulated connection between the receiving body 2.5 and the base body 1.5 corresponds essentially to the exemplary embodiment as was described with reference to FIG. 1.

The adjustment of the receiving body 2.5 to the base body 1.5 takes place via a displaceable part that is designed here as a displacement wedge 4.1. The sliding wedge 4.1 is arranged between the receiving body 2.5 and the base body 1.5. The contact surface 18 assigned to the base body 1.5 and the contact surface 40 assigned to the displacement wedge 4.1 have corrugations in order to enable a grippy contact between the base body 1.5 and the displacement wedge 4.1.

The position of the receiving body 2.5 relative to the base body 1.5 is changed by moving the sliding wedge 4.1. on the z axis.

In the embodiment shown in FIG. 5, a toothing 41 is attached to the side of the sliding wedge 4.1, into which a pinion 511 engages as part of an adjustment tool 510. The setting tool 510 is in a bore formed on the base body 1.5 integrally formed tab 19. By rotating the setting tool 510, the shifting wedge 4.1 can be shifted on the z-axis and thus the inclination of the receiving body 2.5 relative to the base body 1.5 can be changed.

This position and the window pane are fixed by means of a fastening screw 28.3, which engages through cutouts in the base body 1.5, visible in FIG. 5 (but not designated), in the displacement wedge 4.1, in the receiving body 2.5 and in the window pane (not shown). This fastening screw 28.3 is assigned a nut, also not shown, so that the window pane can be clamped in the desired position.

The structure of the example shown in FIG. 6 corresponds essentially to the example shown in FIG. The adjustment of the sliding wedge 4.2 takes place here via an adjusting bolt 43 mounted centrally in the receiving body 2.6 in a bore 42. This adjusting bolt 43 has a toothing 43.1 which is connected to an internal toothing 44.2 which is provided on one side in a recess 44.1 of the sliding wedge 4.2. By turning the adjusting bolt 43, the shifting wedge 4.2 can be moved in the z direction and the desired position can thus be realized.

A fastening screw 28.4 engages in a threaded hole 43.2 of the adjusting bolt. This allows the window pane to be clamped in the desired position.

An advantageous embodiment of the contact surfaces between the sliding wedge 4.2 and the base body 1.6 consists in forming them as curved surfaces. The radii R; R 'the arcuate Areas are approximately the same size and have a common center, not shown here. As a result, a full-surface contact is achieved with each position of the sliding wedge 4.2 relative to the receiving body 2.6.

A solution is shown in FIGS. 7 and 8, in which the adjustment also takes place via a sliding wedge 4.3.

The structure of the receiving body 2.7 corresponds essentially to the example described with reference to FIG. 3. The window pane, not shown, is received in an insert 25.3 and clamped over the receiving plate 24.3 and the holding plate 25.3. The connection of the receiving body 2.7 to the basic body 1.7 takes place via the engagement of fingers 35.3 arranged in the upper part of the receiving plate 24.3 in recesses 13.2 in the basic body 1.7 corresponding to these.

The sliding wedge 4.3, the contact surfaces of which are designed as curved surfaces in the form of a circular arc, as in the previous example, is arranged between the base body 1.7 and the receiving plate 24.3. A recess 44.2 is arranged in the middle of the sliding wedge 4.3, in which an eccentric 53 is mounted. The engagement in the eccentric 513 is designed as an internal hexagon 514, in which a bushing 515 engages with an external hexagonal contour.

This socket 515 is positively mounted with its hexagonal outer contour in a hexagon socket 451 of the adjusting bush 45. This hexagon socket 451 continues as a threaded hole 453, the adjusting bush 45 being provided with an hexagon socket 452 in this area. A clamping screw 12 with a screw head 12.4, which has a collar 12.3, which bears against the base body 1.7, is arranged within the bush 515. The other end of the clamping screw is provided with an external engagement 12.1, which is designed, for example, as a Torx or external hexagon. The shaft of the clamping screw 12 carries a thread 12.2 which is in engagement with the thread 453 of the adjusting bush 45.

To change the inclination of the receiving body 2.7 and thus the inclination of the window pane, proceed as follows:

The external hexagon 452 of the adjusting bush 45 is gripped and rotated using a suitable tool. The rotary movement is transmitted via the hexagon socket 451 of the adjusting bush 45 to the bush 515 and thus to the eccentric 513. This moves the shifting wedge 4.3 on the z-axis, so that the position of the receiving body 2.7 relative to the base body 1.7 is changed.

If the desired position has been reached, this position is fixed by gripping the clamping screw 12 on its external engagement 12.1 with a suitable tool and tightening it in relation to the adjusting bush 45. The external hexagon 452 of the adjusting bush 45 is held.

FIG. 17 shows a solution in which a displacement wedge 4.6 is arranged between the base body 1.6 and the receiving body 2.6. This sliding wedge is arranged so that its taper points in the x direction.

When moving the sliding wedge 4.6 in the x direction

(Direction of arrow) slide the contact surfaces 40.1; 40.2 of

Sliding wedge on the associated contact surfaces 181 am Base body 1.6 'or on the contact surface 231 on the receiving body 2.6'. This results in the pivoting of the receiving body 2.6 'to the base body 1.5' around the articulated connection which can be seen in FIG.

In order to achieve the full-surface contact of the contact surfaces 181, 231, these are provided with a set not shown in the figures.

The adjustment of the sliding wedge 4.6 is carried out with setting means as have already been described in the examples above.

A further variant of the solution is described in FIG. 9 in conjunction with FIG. 10. Here, the window pane 7 is held between a holding plate 26.4 and a displaceable part 4.4, an insert 25.4 being located between the holding plate 26.4 and the window pane 7. This unit is clamped to the base body 1.8. The bracing is realized by a fastening screw 28.5 screwed into the holding plate 26.4, which leads through corresponding recesses (not shown in the figures) and fixes the window pane 7.

The displaceable part 4.4 consists of two firmly connected segments 4.4 ', 4.4 ". The segments 4.4', 4.4" have contact zones 46.1 '; 46.1 ", which are connected to contact areas 47.1 ', 47.1" of the base body 1.8.

In order to lay the contact zones 46.1 '; 46.1 "to the contact areas 47.1 ', 47.1" during the displacement, both the contact zones 46.1'; 46.1 "as well as the contact areas 47.1 ', 47.1" assigned to them as curved arcs. shapes. The radius R1 of the upper segment 4.4 'is larger than the radius R2 of the lower segment 4.4 ". Both have a common center point M (see FIG. 10).

In order to change the position of the window pane 7, the displaceable part 4.4 is moved on the z-axis. The receiving body 2.8 moves with the window pane 7 around the center M.

The center M does not move during the setting process. The point A marked in FIG. 10 is the point at which the perpendicular from the center M to the surface of the window pane 7 forms a right angle with the tangent at this point. As a result of the shift, this point A also has an upward movement component (z direction). Since the window pane is only fixed after the adjustment process, this can be corrected. Thus, as shown in FIG. 10, the disk body apparently pivots around point A during the adjustment.

These geometrical conditions make it possible to place point A at a desired location with appropriate dimensioning of the radii R1, R2.

However, the invention is not limited to the formation of the contact zones 46.1 '; 46.1 "and the contact areas 47.1 ', 47.1" as arcuate surfaces with the above-described design of the radii. It is also possible to design them as arbitrarily curved or as flat surfaces. However, no full-area system is achieved with this. The contact zones or contact areas designed in this way have a line contact, this line moving when the segments are shifted. Such a solution is shown schematically in FIG. 11. In the position drawn with solid lines, the contact zones 46.2 ', 45.2' touch the contact areas 47.2, 47.2 "in the points P1, P2. The slopes of the tangents T1, T2 at this point are different. The condition must be met that the tangent T2 has a smaller slope with respect to the x direction than the tangent Tl. The orthogonals of the tangent Tl, T2 meet at the instantaneous pole MP '.

When the displaceable part 4.5 moves on the z axis, the points P1, P2 move around the instantaneous pole MP '. Another position of the displaceable part 45 is drawn in as a broken line. It can be seen that the slope of the tangents Tl, T2 'change at the new contact point Pl', P2. This results in a new instantaneous pole MP ". It becomes clear that the instantaneous pole MP" shifts with respect to the instantaneous pole MP '. This gives the designer the option of designing the course of the contact zones 46.2 '; 46.2 "and the contact areas 47.2, 47.2 determine the movement of the instantaneous pole MP ', MP" and thus the adjustment path of the window pane 7. The shifting of the window pane 7 in the z direction that occurs can be compensated for before it is finally fixed in the desired position.

The course of the movement of the instantaneous pole shown in FIG. 11 represents the general case. The example shown in FIGS. 9 and 10 applies as a special case, since the design of the radii R1 and R2 does not cause the momentary pole MP to move.

The segments can be shifted using the means as have already been explained. This includes, for example, adjustment via a setting pinion, which in a toothing attached to the side of the displaceable part engages (see FIG. 5). These means are not shown in FIGS. 9 to 11.

A further embodiment of the invention is shown in FIGS. 12 to 16. Here too, the window pane 7 is held between a holding plate 26.5 and a displaceable part 4.5. There is an insert 25.5 between the holding plate 26.5 and the window pane 7. This unit (adhesive plate 26.5, insert 25.5) is clamped to the base body 1.9. The bracing is realized by a fastening screw 28.6, which leads through corresponding recesses, not shown in the figures, and is screwed to the holding plate 26.5. This fixes the window pane in the target position.

The displaceable part 4.5 consists of two segments 4.5 'and 4.5 ", which are connected to one another via a flexible web 4.5' ''. The segments 4.5 'and 4.5" are designed as wedges lying on the x-axis with different wedge angles, ß. The position of the segments with the wedge angles α, β can be seen from the sectional representations shown in FIGS. 13 and 14. The tapering of the wedges always point in the same direction. The segments 4.5 'and 4.5 "lie on the window pane 7 with contact surfaces 48.1', 48.1". Opposite, the segments 4.5 ', 4.5 "are provided with contact surfaces 47.3', 47.3", which bear against contact zones 46.3 ', 46.3 "of the base body 1.9.

The contact surfaces 47.3 ', 47.3 "and the contact zones 46.3', 46.3" are just executed here. However, it is also possible, analogously to the previous example, to provide a line or point contact between the two, the tangent of which at the point of contact between the contact surface 47.3 ', 47.3 "and the contact zone 46.3 ', 46.3 "in the x direction and has different slopes.

The mode of operation of the driver described above is to be explained with reference to FIGS. 15 and 16. The movable part 4.5 is shown here in two different positions. In this representation, the holding plate 26.5 including the window pane 7 is not shown in order to clarify the geometric conditions.

When shifting on the x-axis, the different wedge angles α, β result in a different displacement of the support surfaces 48.1 ', 48.1 "in the y direction, the flexible web 4.5" being deformed. Thus, the window pane, not shown here, is rotated about an axis lying on the x-axis, so that a change in the position of the window pane and an exact contact with the vehicle body can be realized.

In order to maintain the full-surface contact of the contact surfaces 48.1 ', 48.1 "on the window pane, the contact surfaces 47.3', 47.3" or the contact zones 46.3 ', 45.3 "are provided with a setting not shown in the figures.

The stiffening of the sliding part 4.4; 4.5; 4.6 takes place with setting means, as already described in the above examples.

In a further embodiment of the invention, it is proposed not to connect both segments rigidly or flexibly to one another, but to arrange them individually. The segments can then be shifted independently of one another by means of setting means, as a result of which predetermined movement let implementation processes be realized. This arrangement also makes it possible to move both segments synchronously.
