Description

The invention relates to a window regulator for adjusting a window pane of a motor vehicle and to a method for adjusting a window regulator.

Such a window regulator comprises a guide plate, an adjustment part guided on the guide plate along a displacement path and at least one stop device which defines an end position of the displacement path. The window pane can be fastened to the adjusting part, so that the window pane can be moved by moving the adjusting part relative to the guide plate. For example, in a closed position of the window pane, the stop device should provide a defined stop, so that the window pane is in a defined position in the closed position.

Particularly in convertibles, so-called web-controlled window regulators are used, which have on a guide plate a plurality of curved guide rails which predetermine a curved guide track for the window pane to be adjusted. By means of such web-controlled window regulators, a change in position of the window pane on its displacement path can be effected in order to bypass components arranged in the body, for example a wheel arch. This may be necessary, in particular in cabriolets, to take account of space limitations, for example a rear wheel arch, which is to be avoided when lowering a window pane.

In frameless vehicle doors of a convertible also eliminates the retraction of the window in a seal of a door frame. In such frameless vehicle doors is therefore necessary, in particular to define an upper end position of the adjustment. This is done by one or more stop devices which provide one or more stops for the adjustment part, so that in a top end position a defined position of the adjustment part is predetermined relative to the guide plate.

Such an anchor device must be adjusted during assembly of the window regulator on a vehicle to adjust a desired end position in an exact manner. This increases the assembly costs. There is therefore a need for a stop device that allows the simplest and most accurate adjustment possible.

From the DE 20 2011 051 890 U1 a track-controlled window is known in which two mutually coupled stops are provided for adjusting an end position of an adjustment relative to a guide plate.

From the DE 10 2007 014 098 A1 is a web-controlled window regulator is known in which a stop element is adjustable via a coupling lever.

From the DE 10 2007 023 001 A1 is a web-controlled window regulator is known, in which on a support plate, a protruding tab is formed, which cooperates with a movable along the carrier plate arranged carrier for forming an intended for the driver adjustable end stop.

Object of the present invention is to provide a window with a stop device that allows the simplest possible adjustment for defining an end position of an adjustment.

This object is achieved by an article having the features of claim 1.

Accordingly, the stop device has a carrier part and an adjusting part which can be adjusted to the carrier part in an adjustment direction and provides the stop between the guide plate and the adjusting part in the end position, the carrier part having at least one first latching device and the adjusting part having at least one second latching device and the at least a first latching device and the at least one second latching device are engaged with each other in such a way that the adjustment part is movable in the adjustment direction relative to the support part, whereas a movement counter to the adjustment direction is blocked.

The present invention is based on the idea of providing an abutment device in which an adjustment part can be moved relative to a carrier part only in a direction of adjustment, but not counter to the direction of adjustment. For this purpose, the support member and the setting on latching means are latching with each other, wherein the locking devices are configured such that in the adjustment ratcheting adjustment of the adjustment relative to the support member is possible, against the adjustment direction but an adjustment is locked in a positive manner.

The use of such an abutment device allows easy adjustment of an end position. Thus, for adjusting a window (initially not yet aligned stop means) in a desired position, for example, a closed position, are moved to then adjust the adjustment so in the adjustment direction relative to the support member, that a closing position corresponding stop for limiting the Adjustment is set. Characterized in that the adjusting member only in the adjustment direction relative to the Carrier part can be moved, the adjustment part retains its position in the adjustment, so that the adjustment can be easily and accurately performed without much effort.

During subsequent operation of the window lifter, the stop device then specifies a limitation for the adjustment path, so that the adjustment path is defined via the stop device and thus, for example, the closing position is predetermined.

The at least one first latching device and the at least one second latching device are preferably designed in each case as toothing, for example as a sawtooth-shaped toothing. The toothing is shaped so that an adjustment of the adjusting member relative to the support member in the adjustment direction is possible, but not contrary to the adjustment direction.

Preferably, the carrier part has a carrier body, are arranged on the mutually parallel, transversely to the adjustment direction spaced apart side walls which receive the adjusting member between them. In this case, a first latching device is advantageously arranged on each side wall, which is in engagement with an associated, second latching device on an edge of the setting part.

For example, toothings may be formed on the side walls, which are in engagement with associated toothings on side edges of the setting part. The sidewalls extend along the direction of adjustment and provide therebetween an adjustment path for moving the adjustment member in the adjustment direction.

In order that a ratcheting movement of the adjusting member relative to the support member is possible in the adjustment direction, without this being blocked by the locking devices, the support member may be formed, for example, of plastic and elastic at least in sections, so that the at least one second locking means of the adjustment in the adjustment can be moved away in ratcheting manner via the at least one first latching device of the carrier part. In particular, due to an elasticity in the carrier part, the first latching devices of the carrier part can dodge transversely to the adjustment direction, so that the adjustment part can be moved in the adjustment direction. A movement of the adjusting member against the adjustment direction, however, locked in a form-fitting manner and prevented by engagement of the locking devices into each other.

The support member is preferably fixed to the guide plate (which in principle it is also possible to arrange a stop device of the type described here on the adjustment). In order to fix the carrier part against rotation on the guide plate, one or more projection elements can be provided on the carrier part, for example, which engage in associated recesses on the guide plate and ensure a secure and firm hold of the carrier part on the guide plate. The support member is thus secured against rotation on the guide plate, so that the support member can not tilt to the guide plate during operation of the window regulator.

For adjustment, the adjustment is moved from an initially unadjusted position in the adjustment direction relative to the support member to specify in this way a stop for defining a desired end position of the adjustment. By the latching devices is thereby effected that during adjustment no back movement can be carried out against the adjustment direction. In order to ensure in later operation that no adjustment of the adjustment can be done from a set, adjusted position, a fixing device is additionally advantageously provided which is adapted to fix the support member and the adjustment in a set, adjusted position to each other, for example in that the support part and the adjustment part are clamped together.

The fixing device may, for example, have a threaded bolt which is fixedly fixed to the setting part and engages through the support part at an elongated hole elongated along the adjustment direction. The bolt can be brought into engagement with a nut, so that by the bolt-nut-composite, the support member and the adjusting member for fixing a set position can be clamped together.

The bolt is held on the adjusting member and is moved together with the adjusting member in the direction of adjustment. In order to allow a relative movement of the bolt relative to the support member, the bolt passes through the elongated slot on the support member, so that the bolt can be moved in the slot.

In addition, the bolt can also pass through an elongated, directed in the direction of adjustment slot on the guide plate. The bolt can be brought in this way with a arranged on a side facing away from the carrier part of the guide plate nut into engagement, wherein the bolt is movable in the slot and thus the adjusting member relative to the guide plate is adjustable. By means of the bolt-nut-composite can be clamped in this way in a fixed position, the adjusting part both with the support member and with the guide plate.

The adjustment part comprises in an advantageous embodiment, a base body which carries the at least one second locking device. For example, a latching device in the form of a (sawtooth) toothing can be arranged on lateral edges of the base body, which face the side walls of the support member, which is in engagement with a toothing of an associated side wall of the support member.

An abutment head is advantageously formed on the base body, which serves to provide the abutment and projects transversely to the adjustment direction (in the vehicle transverse direction, with respect to the usual vehicle coordinate system) from the base body. The stopper head may for example be designed in the manner of a hook and identify a notch for providing a defined system for the adjustment.

The main body may be made of metal, for example of steel, for example. For example, the base body can be produced as a (bent) sheet steel part. The stopper head is molded in this case preferably made of plastic to the base body by means of plastic injection molding. In this way, a damping can be provided in a striking against the stopper head. In addition, a stop can be formed, which is adapted in its shape to the abutting component, for example, the adjustment part.

In order to ensure that the adjustment part can not tilt to the guide plate, in particular after the adjustment during operation of the window lifter, the base body preferably has an engagement piece that engages in an opening of the guide plate and thus provides a tilt lock. The associated opening on the guide plate is preferably extended longitudinally along the adjustment direction so that the engagement piece can be moved in moving the adjustment in the direction in the opening. However, transverse to the direction of adjustment, the opening provides a guide for the adjustment member so that tilting of the adjustment member relative to the opening is prevented.

The window lifter is preferably configured as a web-controlled window lifter and has a plurality of guide rails, which are curved at least in sections. The guide plate thus defines an adjustment movement of the window pane, which includes changes in position of the window pane during a movement along the guide plate, in particular tilting about the vehicle transverse direction (in the case of a vehicle side window).

The object is also achieved by a method for adjusting a window regulator for adjusting a window pane of a motor vehicle. The window regulator comprises a guide plate, an adjustment part guided on the guide plate on at least one guide rail along a guide track, to which the window pane is fastened, and at least one stop device, which defines an end position of the guide track. In this case, it is provided that the stop device has a carrier part and an adjusting part which can be adjusted in a setting direction relative to the carrier part and which provides a stop between the guide plate and the adjusting part in the end position. The carrier part has at least one first latching device, and the setting part has at least one second latching device. The at least one first latching device and the at least one second latching device are engaged with one another in such a way that the adjustment part is movable in the adjustment direction relative to the carrier part, whereas a movement counter to the adjustment direction is blocked. To adjust the window pane is moved to a closed position, and then the adjusting member is moved in the adjustment direction relative to the support member until an associated edge of the adjustment member is in abutment with the stop.

For the advantages and advantageous embodiments, reference should be made to the foregoing, which applies analogously to the method.

After adjusting the adjustment, the adjustment is in contact with an associated edge of the adjustment. The fixed to the guide plate stopper thus defines an end position of the adjustment of the adjustment in later operation of the window regulator. In order to ensure that in a later operation, the adjusting member is securely and reliably held in position, may additionally be provided that the adjusted position of the adjusting member is fixed relative to the support member by means of a fixing device, for example by the adjustment member and the support member clamped together become.

The idea underlying the invention will be explained in more detail with reference to the embodiments illustrated in the figures. Show it:

1 shows an embodiment of a web-controlled window lift 1 , which is a guide plate 2 and an adjusting part guided along a (curved) adjustment direction V 3 having. At the guide plate 2 are three guide rails 20 . 21 . 22 trained, with at attachment points 30 . 31 . 32 attached slides 300 (please refer 2 for the slider 300 at the in 1 Right illustrated guide rail 20 ) and a guide for the adjustment 3 provide.

The guide rails 20 . 21 . 22 are at least partially curved and differ from each other, which has the consequence that when moving the adjustment 3 along the adjustment direction V on the guide rails 20 . 21 . 22 the adjustment part 3 undergoes a change in position and in particular to the guide plate 2 is tilted.

At the adjustment part 3 is at attachment points 33 a windowpane 5 established. In a method of adjustment 3 on the guide plate 2 during operation of the window regulator 1 becomes the windowpane 5 together with the adjustment part 3 moves and experiences the same change in position as the adjustment 3 ,

At the guide plate 2 are, transversely to the adjustment V spaced from each other, two stop means 4 arranged, which serve, an upper end position of the adjustment 3 relative to the guide plate 2 pretend. The adjustment part 3 is in the upper end position with the anchor devices 4 in attachment and can not have the anchor devices 4 be moved out. The anchor devices 4 give in this way a defined position of the adjustment 3 in its upper end position.

As seen from the views of the anchor device 4 according to 3 and 4A . 4B can be seen, the stop device 4 a carrier part 40 and an adjustable adjustment part 41 on. The carrier part 40 is stationary and rotationally fixed to the guide plate 2 determined and accesses this with of a carrier body 400 projecting protrusion elements 407 in the form of webs in elongated recess 25 on the guide plate 2 one.

The carrier part 40 has side walls 401 . 402 on, which extend parallel to each other and between them the setting part 41 take up.

The adjustment part 41 has a basic body 410 on, which is designed as a bent metal part, in particular as a sheet steel part, and at its upper end a stopper head 411 wearing. In the area of the stopper head 411 is the main body 410 molded with plastic and shaped so that a notch 412 to provide a defined attack is created.

At his the stop head 411 opposite end, the body 410 an engaging piece 413 in the form of a curved tab, which has a recess 403 on the carrier body 400 the carrier part 40 and an opening 23 on the guide plate 2 passes through and a Verkippsicherung for Einstellsteil 41 relative to the guide plate 2 provides.

On the side walls 401 . 402 the carrier part 40 are latching devices 404 . 405 formed in the form of sawtooth teeth, with locking devices 414 . 415 in the form of saw-toothed teeth on the lateral edges of the body 410 of the adjustment part 41 engage.

The engagement of the gears 404 . 405 . 414 . 415 one inside the other is such that the adjustment part 41 between the side walls 401 . 402 the carrier part 40 can be adjusted in a setting direction E, but not in an opposite direction E 'against the adjustment direction E. Due to the meshing engagement between the adjustment 41 and the carrier part 40 is thus an adjustment of the adjustment 41 relative to the carrier part 40 only possible in the adjustment direction E, but not contrary to the adjustment direction E.

The carrier part 40 is made of plastic, for example, and is in particular in the region of its side walls 401 . 402 so elastic that when adjusting the adjustment 41 in the adjustment direction E, the teeth 404 . 405 on the side walls 401 . 402 transversely to the adjustment direction E (slightly) can escape, so that the teeth 414 . 415 on the body 410 of the adjustment part 41 ratcheting over the gears 404 . 405 on the side walls 401 . 402 can slide. In a countermovement against the adjustment direction E get the teeth 404 . 405 . 414 . 415 However, positively and non-positively engaged with each other, so that such a counter movement is locked.

At the base body 410 of the adjustment part 41 is a bolt 42 attached to a fixing device. The bolt 42 is stationary and preferably also rotationally fixed to the body 410 held and passes through a shaft 421 slots 406 . 24 on the support part 40 and the guide plate 2 , On the shaft 421 can a mother 43 be screwed to - after the adjustment of the anchor device 4 - the adjustment part 41 , the carrier part 40 and the guide plate 2 to fix each other.

The two anchor devices 4 serve to, in the upper end position of the adjustment 3 defined stops for the adjustment 3 provide. In the upper end position is the adjustment 3 - with adjusted anchor devices 4 - with an upper edge 340 of a basic body 34 in the notch 412 of the stopper head 411 each stop device 4 one, so that the adjustment part 3 in a defined position relative to the anchor devices 4 on the guide plate 2 is. This is in 5A . 5B illustrated.

In adjusted position of each anchor device 4 is also the mother 43 on the shaft 421 of the bolt 42 screwed on, leaving the adjustment part 41 and the carrier part 40 together and also with the guide plate 2 are tense. The set position of the adjustment part 41 is thus secured and remains in operation of the window regulator 1 in the set position.

Due to the fact that the lug-shaped engaging piece 413 the guide plate 2 at the opening 23 passes through (see in particular 5B ), is the adjustment part 41 also against tilting relative to the guide plate 2 secured. Due to the fact that the carrier part 40 with the web-shaped projection elements 407 in recesses 25 on the guide plate 2 engages, is the anchor device 4 in fixed, strained state, fixed to the guide plate 2 established.

Because of the adjustment part 41 exclusively in the adjustment direction E relative to the carrier part 40 can be moved, a return movement against the adjustment direction E, however, is locked, resulting in a simple installation and adjustment of each stop device 4 ,

In a starting position before the adjustment, shown in 6A , is the adjustment part 41 in a position relative to the carrier part 40 in which the bolt 42 with his shaft 421 contrary to the adjustment direction E an upper end of the slot 406 on the support part 40 is approximated. The adjustment part 41 can thus be adjusted by a maximum adjustment in the adjustment direction E. For adjustment, the adjustment is 3 with window pane arranged thereon 5 (please refer 1 ) in a (desired) closed position of the window 5 brought and in particular aligned, for example, to an upper roof contour (for example, in a convertible). The adjustment parts 41 the anchor devices 4 on the guide plate 2 are then in the adjustment direction E of the upper edge 340 of the adjustment 3 Approximated until the top edge 340 in the notches 412 the stop heads 411 the anchor devices 4 einliegen (see 6B ). By screwing the nut 43 on the shaft 421 of the bolt 42 on each anchor device 4 become the anchor devices 4 then fixed, so that the location of the adjustment 41 each secured.

In later operation of the window regulator 1 the setting part remains 41 each stop device 4 at its adjusted, secured position, leaving over the adjustment parts 41 the anchor devices 4 the upper end position of the adjustment 3 is predetermined.

Because of the adjustment part 41 can only be moved in the adjustment direction E, but not contrary to the adjustment direction E, the adjustment by simply pressing down the adjustment parts 41 in abutment with the edge 340 of the adjustment 3 take place, and then the respectively set position by tightening the adjustment 41 with the carrier part 40 and the guide plate 2 be secured. Thereby, that a return movement of the adjustment 41 When adjusting is not possible, the adjustment is easy and comfortable to handle.

The idea underlying the invention is not limited to the above-described embodiments, but can in principle be realized even in completely different types of embodiments.

For example, it is basically also conceivable to arrange a stop device of the type described here in kinematic reversal on an adjustment part. Thus, an adjustment part having an adjustable stop means, which cooperates with a fixed stop on the guide plate.

Although described above in connection with a web-controlled window regulator, a stop device of the type described here can in principle also be used with other window regulators for providing a stop.
