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 and a fastening element for fastening the window pane to the adjustment part. The adjustment part extends at least in sections essentially in an extension plane and has at least one attachment opening for fastening the window pane, which is extended parallel to the extension plane, to the adjustment part. The fastener can be fixed to the mounting hole and passes through the mounting hole in a mounting position.

Especially in convertibles so-called web-controlled window lifters are used, which have on a guide plate, a plurality of curved guide rail, which specify a curved guide track for the window 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 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 adjust an upper end position of the adjustment so that the window pane is in a closed position in a defined position relative to a vehicle roof.

It is therefore necessary to be able to adjust the position of the window pane relative to the adjustment part in order to set a desired position of the window pane when mounting a window regulator on a vehicle.

From the DE 10 2005 008 629 A1 For example, a window regulator is known in which a window pane is to be connected to an adjustment part in the form of a driver. At the adjustment part a plurality of fastening elements are provided, which cooperate with clamping devices in openings of the window pane. The clamping devices allow movement of the fastening device within the openings on the window pane, so that the position of the window pane can be adjusted relative to the adjusting section.

The disadvantage of the DE 10 2005 008 629 A1 known arrangement is that in the window pane comparatively large openings must be provided. In order to connect the adjustment part with the window pane via the openings, comparatively large, strongly dimensioned clamping devices are required. This requires a massive design of the clamping devices, which is associated with a comparatively high weight and a large space.

The EP 1 627 981 A1 describes a window, in which a window pane can be connected via a fastening element with a slider. The fastener is in this case arranged in a slot of the slider and thereby movable along a direction to the slider.

At one of the DE 10 2012 207 963 A1 Known power window is an adjustment in the form of a driver part is connected via openings in openings fasteners with a window. In a pre-assembly with not yet arranged on the adjustment window, the fasteners are not set to the adjustment or connected to the adjustment.

The object of the present invention is to provide a window lifter and a method for adjusting a window lifter, which provide a adjustability of a window pane relative to an adjustment part in a simple, cost-effective manner.

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

Accordingly, a connecting device is provided which, at least in a preassembly position with window pane not yet attached to the adjusting part, connects the fastening element to the adjusting part such that the fastening element is adjustable along at least one direction in the plane of extent relative to the adjusting part.

The present invention is based on the idea of pre-positioning the fastening element via a connecting device on the adjusting part in such a way that the fastener can be adjusted relative to the adjustment. The fastening element can thus be fixed in a non-adjustable manner on the window pane. An adjustability of the window pane relative to the adjustment part is provided by the fact that the fastening element is movable relative to the adjustment part in the extension plane.

The adjusting part extends in a planar manner along the plane of extension which corresponds to the pane plane in which the window pane extends. At least one fastening opening is provided on the adjusting part, on which the fastening element is arranged. In order to allow an adjustability of the fastening element relative to the adjusting part, the fastening opening on the adjusting part is designed so large that the fastening element can be moved in the plane of extension in the fastening opening.

In a preassembly position, the fastening element is held on the connecting device at the at least one fastening opening. In order to adjust the window pane relative to the adjustment part, the fastening element can be adjusted out of its preassembly position and moved in the fastening opening, so that the fastening element is in an adjustment position outside its preassembly position.

The connecting device has a carrier part on which the fastening element is arranged. The support member is connected via at least one mounting arm, at least in the pre-assembly with the adjustment. The carrier part preferably has an opening in which the fastening element designed as a screw, for example, is arranged, so that the fastening element is held on the carrier part.

To secure the fastener, for example, for the delivery of the window by a supplier to the support member, the fastener, such as a screw, for example, with the support member are in threaded engagement. For this purpose, in the opening z. Example, a self-locking thread may be provided, so a thread that secures a rotational position of the fastener relative to the support member. Such a self-locking thread, for example, have a sufficient stiffness, so that unscrewing the fastener from the support member is not readily, at least not inadvertently, possible.

Such binding can be provided, for example, by initially not providing any thread in the opening of the carrier part and only cutting the thread into the opening by screwing in the fastening element.

Or the thread form of the thread in the opening may (slightly) deviate from a thread of the fastener.

It is also possible to provide a so-called trilobular thread on the fastening element and / or the opening of the carrier part. As a "trilobular" is a geometric figure called, which is also called "triangle-round". A trilobular has a triangular basic shape with rounded corners and a constant roll diameter. In a trilobular thread, the threads do not run along a circular cylindrical surface, but along a lateral surface with a trilobular cross-section.

The connecting device with its carrier part and the at least one connecting arm is preferably made of plastic. Likewise, the adjustment can be made of plastic.

Conceivable and possible in a specific embodiment, for example, to form the connecting device and the adjusting part in one piece, for example by means of plastic injection molding.

The carrier part preferably comprises a collar which surrounds the opening and projects into the at least one fastening opening. By means of the collar can be ensured on the one hand that the fastener is reliably held over a sufficiently large opening edge on the support member. In addition, a stop contour can be provided on the collar, which limits the adjustability of the fastener in the mounting hole and rests in maximum deflected position of the fastener to a border of the mounting hole of the adjustment.

In a first variant of the connecting device, the at least one fastening arm is designed to be elastically resilient at least in sections and fastened to the adjusting part via an attachment point at an end remote from the carrier part. Due to the elastically resilient design of the at least one fastening arm, the fastening element can be moved along the extension plane in the fastening opening, so that the position of the fastening element can be changed relative to the adjusting part.

For example, in this case, the connecting device has three attachment arms which extend at an angle of 120 ° in the plane of extension of the support member and establish a three-armed connection of the support member with the adjustment.

It is conceivable, as I said, to produce the connecting device in one piece with the adjustment. In this case, the attachment arms are integrally connected to the adjustment.

It is also conceivable and possible, however, to produce the connecting device as a separate component to the adjusting part and to detachably connect it to the adjusting part. In this case, for example, clip elements can be provided on the at least one fastening arm, by way of which the connecting device can be connected to the adjusting part in a latching manner.

In a second variant, the at least one fastening arm is configured as a substantially rigid arm and can be released from the adjusting part along the at least one direction in the plane of extension for adjusting the fastening element. The adjustability is thus provided, in this variant, not by an elasticity in the one or more attachment arms, but in that the one or more attachment arms can be released from the adjustment. In the pre-assembly, the carrier part of the connecting device is connected via the at least one fastening arm with the adjusting part. In order to move the fastening element in the fastening opening of the adjusting part for adjusting the window writing relative to the adjusting part, the at least one fastening arm can be released from the adjusting part, so that the fastening element is no longer held in position in the fastening opening and can be moved in the fastening opening ,

Such releasability of the attachment arm relative to the adjustment part can be provided in different ways.

For example, in the pre-assembly position, the at least one fastening arm can be connected to the adjustment part at a end remote from the carrier part via a predetermined breaking point. At the predetermined breaking point, the at least one fastening arm can be broken away from the adjusting part, so that there is no longer any connection between the fastening arm and the surrounding adjusting part and the carrier part of the connecting device can be moved together with the fastening element arranged thereon in the fastening opening.

A predetermined breaking point can be created, for example, by reducing the material thickness at a connection point between the at least one fastening arm and the adjusting part, compared with a wall thickness of the adjusting part and / or with respect to the material thickness of the at least one fastening arm.

Alternatively or additionally, a notch or a perforation may be provided at the connection point.

In all these cases, the connecting device is preferably integrally and integrally formed with the adjusting part and connected in one piece with the adjusting part in the pre-assembly position. To release the connecting device, the at least one fastening arm is broken away from the adjusting part, so that the connecting device can be moved overall relative to the adjusting part.

It is also conceivable here that the carrier part is arranged on a surface section of the adjustment part and the surface section is surrounded by a perforation line. The surface portion can thus be broken away along the perforation line from the adjusting part in order to move the carrier part of the connecting device together with the fastening element arranged thereon relative to the adjusting part.

It is also conceivable and possible for the at least one fastening arm to be clamped on an opening edge surrounding the at least one fastening opening. For this purpose, the connecting device can be produced, for example, in one piece with the adjusting part and then be cut out of the adjusting part. By re-insertion into the attachment opening provided on the adjusting part, a clamping hold of the connecting device can then be produced in the fastening opening, so that the fastening element is connected (detachably) to the adjusting part in the pre-assembly position.

For adjusting the position of the window pane relative to the adjusting part, in the variant and its modifications described above, the connecting device is released from the adjusting part, so that the fastening element can be moved in the plane of extent relative to the adjusting part. In order to ensure that a mobility of the fastener is given translationally in the plane of extent, but the connecting device does not rotate with a screwing screwing of the fastener in the carrier part of the connecting device, it is preferably provided that at least one mounting arm in a dissolved state of the adjustment in engages a recess of the window pane or of a component connected to the window pane, so that a rotation-proof hold of the connection device on the window pane or the tree element connected to the window pane is created above it.

For example, a spacer element can be arranged on the window pane, which provides a distance between the adjustment part and the window pane. At this spacer element can be provided for each mounting arm a recess be, which receives a remote from the support member of the connecting device end of the associated mounting arm and holds in the dissolved state, the connecting means such that the connecting means can not be rotated by a plane perpendicular to the plane of extension. The fastening element can thus be screwed, for example, screwed into the support member without the support member can rotate.

Regardless of the specific variant of the connecting device, the fastening part preferably engages in an assembly position an opening of the window pane and sets the window pane on the adjustment. The opening of the window pane for the passage of the fastening element can here be made small and adapted to the diameter of the fastening element. In particular, the fastening element is not or at least only slightly adjustable along the extension plane in the opening of the window. An adjustability of the fastening element for adjusting the window pane relative to the adjusting part is provided (mainly) in the fastening opening of the adjusting part.

In the assembly position, a spacer element between the adjustment part and the window pane is advantageously arranged. The spacer element has a penetration point for the fastening element, on which the fastening element passes through the spacer element. If a plurality, for example three fastening elements for connecting the adjusting part to the window pane are provided, then the spacer element has a plurality of, for example, three penetration points, wherein the individual penetration points are connected to one another via arms.

In the assembly position is preferably further arranged on a side facing away from the adjusting part of the window pane, a counter-fastening element from the interaction with the fastening element for connecting the window pane with the adjusting part. If the fastening element is designed, for example, as a screw, then the counter-fastening element is configured as a nut, wherein a plurality of fastening elements corresponding to a plurality of counter-fastening elements are provided when used, which are connected to one another via arms, so that a uniform, one-piece tree element is created.

The counter-fastening element is preferably prepositioned on the window pane. For this purpose, the counter-fastening element, for example, have clip elements which pass through the opening of the window pane in a prepositioned position and engage, for example, in a penetration point of the spacer element, so that a prepositioned composite of counter-fastening element, window pane and spacer element is created. As a result, the assembly is simplified because the adjustment can be recognized with the attached fastener in a simple, comfortable way to the prepositioned composite of counter-fastening element, window and spacer.

• – ein an der Führungsplatte geführtes Verstellteil, das sich zumindest abschnittsweise im Wesentlichen in einer Erstreckungsebene erstreckt und mindestens eine Befestigungsöffnung zum Befestigen der parallel zur Erstreckungsebene erstreckten Fensterscheibe an dem Verstellteil aufweist, und
• – ein Befestigungselement, das zum Befestigen der Fensterscheibe an der mindestens einen Befestigungsöffnung angeordnet ist.

The object is also achieved by a method for adjusting a window regulator for adjusting a window pane of a motor vehicle. The window lift includes

• A guide plate,
• - An guided on the guide plate adjustment part, which extends at least partially substantially in an extension plane and at least one mounting opening for fixing the plane parallel to the extension plane extending window on the adjustment part, and
• - A fastening element which is arranged for fastening the window pane to the at least one fastening opening.

In this case, it is additionally provided that a connecting device, at least in a preassembly position at not yet attached to the adjustment window the fastener connects to the adjustment and adjusted to adjust the window pane relative to the adjustment the fastener in at least one direction in the extension plane relative to the adjustment ,

The above-described advantages and advantageous embodiments are analogous to the method application, so that reference should be made to the above.

To adjust the window regulator, the window pane is preferably first connected via the fastening element to the adjustment part, wherein the connection is such that the window pane is indeed held on the adjustment part, but can still be adjusted in the extension plane relative to the adjustment part. Then, the window pane is positioned relative to the adjusting part along the extension plane and thus adjusted in position relative to the adjusting part. Subsequently, the connection between the adjusting part and the window pane for fixing the position of the window pane is fixed relative to the adjusting part in the plane of extent, and thus the window pane is fixed to the adjusting part.

To fix the window pane on the adjusting part, the fastening element is brought into connection with the associated counter-fastening element, for example by the Fastening element is screwed in the manner of a screw in the associated counter-fastening element in the manner of a nut to clamp in this way the window pane with the adjustment. In the final mounted position, the window pane is then securely held on the adjusting part.

The adjustment of the window should be made in particular on a frameless French window with respect to a roof contour to ensure that in a closed position of the window, a window opening is closed completely and in a sealed manner. To adjust the window pane is therefore preferably brought into a closed position relative to the roof contour and aligned relative to the roof contour to - to fix the connection between the adjustment and the window pane - after alignment of the window pane. An adjustment of the window pane relative to the adjustment part is possible due to the adjustable arrangement of the fastening element on the adjustment part, wherein for adjusting the fastening element is moved in the associated mounting opening on the adjustment and then, after adjustment, the connection between the adjustment and the window secured becomes.

1 shows a schematic view of a window regulator 1 in the form of a web-controlled window lifter, which is a guide plate 2 and an adjustment part guided thereon 3 having. At the adjustment part 3 is a windowpane 4 set, so that by adjusting the adjustment 3 along an adjustment direction V, the window pane 4 can be moved to raise or lower.

The guide plate 2 has three guide rails 20 . 21 . 22 on where the adjustment part 3 over at attachment points 33 mounted slider is guided. The guide rails 20 . 21 . 22 are each at least partially curved and give a curved track for the window pane 4 in front. When adjusting the window pane 4 along the adjustment direction V is the a the lifting position of the window pane 4 changed, but at the same time the position of the window 4 adjusted by a vehicle transverse direction Y, so that the window 4 is also adjusted in its pivot position. By means of such a web-controlled window lifter 1 can body elements, such as a wheel well, when lifting and lowering the window 4 be avoided in order to take into account this limited space conditions.

The adjustment part 3 serves to connect the window pane 4 to the guide plate 2 and is drivable via a suitable electromotive drive device. The adjustment part 3 has several mounting holes 33 on, which are each penetrated by a fastener to the window pane 4 on the adjustment part 3 as will be explained below.

2 shows the adjustment part 3 at the windowpane 4 , The adjustment part 3 extends flat in an extension plane E, which is parallel to the window plane, ie to the plane of extension of the window 4 , is located. The extension plane E is directed substantially perpendicular to the vehicle transverse direction Y.

To set the adjustment part 3 at the windowpane 4 become a spacer element 6 and a carrier element 5 (Nut carrier) used on both sides of the window 4 are arranged, wherein the spacer element 6 between the windowpane 4 and the adjustment part 3 and the carrier element 5 on one of the adjustment part 3 opposite side of the windowpane 4 to come to rest.

The spacer element 6 has three access points 60 - 62 up, over arms 63 connected to create a triangular component. At the two upper passages 60 . 62 is ever a stop 64 arranged for hanging the windowpane 4 on the adjustment part 3 for simplified installation. [Is this true?]

The carrier element 5 has three counter-fastening elements 50 - 52 up, over arms 53 are interconnected to create a substantially triangular component. With the counter-fastening elements 50 - 52 can one the openings 30 - 32 of the adjustment 3 thorough fastening element 8th be screwed engaged, so that over the counter-fastening elements 50 - 52 a bracing connection between the adjustment 3 and the windowpane 4 can be produced.

A first embodiment of an adjustment 3 with on the adjustment 3 via connecting devices 7 arranged fasteners 8th demonstrate 3 to 8th , At each mounting hole 30 - 32 (shown in 3 to 8th is only the mounting hole 30 ) is a fastener 8th arranged in the form of a screw. The fastener 8th is via a connection device 7 with the adjustment part 3 connected. The connection device 7 has a support part 70 with a central, from a covenant 701 surrounded opening 700 on, in which the fastener 8th is held screwed. The carrier part 70 is about three by 120 ° about the vehicle transverse direction Y spaced from each other fastening arms 71 - 73 with the adjustment part 3 connected.

In the embodiment according to 3 to 8th are the attachment arms 71 - 73 designed elastically resilient and extend meandering between the support member 70 and at distal ends of the attachment arms 71 - 73 arranged attachment points 710 - 730 , About the attachment points 710 - 730 and clip elements arranged thereon 711 - 731 are the attachment arms 71 - 73 at attachment points 301 - 303 around the respective mounting hole 30 - 32 around at the adjustment part 3 set as in 7A and 7B is shown.

The fastener 8th is designed in the manner of a screw and has one on one of the window pane 4 opposite side of the adjustment 3 arranged screw head 80 and a shaft 81 on. In a pre-assembly is the fastener 8th in the form of the screw partially in the opening 700 on the support part 70 screwed in, like this in 7A is shown. The fastener 8th is thus in the pre-assembly via the connecting device 7 with the adjustment part 3 connected and relative to the adjustment 3 prepositioned.

To connect the fastener 8th with the carrier part 70 can in the opening 700 be provided an internal thread, which is preferably designed self-locking, so that an (undesired) rotation of the fastener 8th in the opening 700 is at least more difficult. A binding in threaded engagement between the fastener 8th and the carrier part 70 can be provided, for example, that the thread forms of the fastener 8th and the carrier part 70 (slightly) differ from each other. It is also conceivable that at least one of the threads is designed as a trilobular thread. Again alternatively, it is also conceivable that the thread in the carrier part 70 only by screwing in the fastener 8th is cut.

About the elastically resilient mounting arms 71 - 73 is the fastener 8th in an adjustable manner to the assigned fastening opening 30 - 32 of the adjustment 3 held. In particular, in this way an adjustability of the fastener 8th in the plane E of the adjustment 3 provided an adjustment of the windowpane 4 relative to the adjustment 3 allows.

How out 7B visible, stands the federal government 701 the carrier part 70 in the associated mounting hole 30 - 32 of the adjustment 3 into it. By the axial from the carrier part 70 above covenant 701 becomes a strong attachment of the fastener 8th on the support part 70 created with sufficient axial thread length. In addition, the federal government 701 a stop on the border of the associated attachment opening 30 - 32 at maximum deflection of the fastener 8th in the extension plane E available.

For mounting the windowpane 4 on the adjustment part 3 First, the windowpane 4 with the spacer element 6 and the carrier element 5 connected. For this purpose, the spacer element 6 on the one hand and the carrier element 5 on the other hand to the windowpane 4 scheduled, so that clip elements 500 on the counter-fastening elements 50 - 52 the carrier element 5 openings 40 - 42 at the windowpane 4 reach through and latching with openings 600 at the passages 60 - 62 of the spacer element 6 come into engagement, as can be seen from a synopsis of 2 . 4 and 5 results. By applying the spacer element 6 and the carrier element 5 to the windowpane 4 become the spacer element 6 and the carrier element 5 thus on the windowpane 4 prepositioned.

Then the composite of windowpane 4 , Spacer element 6 and carrier element 5 to the adjustment 3 be set, with first the fasteners 8th at the mounting holes 30 - 32 in the pre-assembly according to 7A are located. Around the windowpane 4 on the adjustment part 3 to fasten, the fasteners 8th each with a shaft 81 in an associated counter-fastening element 50 - 52 the carrier element 5 screwed in, like this in 4 is shown.

Around the windowpane 4 relative to the adjustment 3 to adjust, the window will 1 moved to a position in which the window pane 4 is in its (nominal) closed position. In this closed position, the window pane 4 - Not yet completely in the carrier element 5 screwed fasteners 8th - relative to a roof contour 9 (please refer 1 ) aligned to a desired, sealing position of the windowpane 4 in the closed position for later operation. Then the position of the windowpane 4 relative to the adjustment 3 fixed by the fasteners 8th further into the counter-fastening elements 50 - 52 the carrier element 5 be screwed in and the windowpane 4 thus relative to the adjustment 3 is strained.

When adjusting the window pane 4 There is a relative movement of the window 4 to the adjustment part 3 in the plane of extension E. As a result, the fasteners move 8th in the associated mounting holes 30 - 32 of the adjustment 3 , which is due to the elastically resilient connection of the fasteners 8th via the associated connection devices 7 to the adjustment 3 is possible. In adjusted position of the windowpane 4 are the fasteners 8th thus (possibly) relative to the associated mounting holes 30 - 32 deflected, like this in 8th is shown.

A second embodiment of an adjustment 3 with over connecting devices 7 arranged thereon fasteners 8th is in 9A . 9B to 16 represented, wherein in the figures, the adjustment part 3 only partially in the area of a mounting hole 32 and a fastener disposed therein 8th is shown.

In the embodiment according to 9A . 9B to 16 is a fastener 8th via a connection device 7 , which is an annular support part 70 and four cross-shaped mounting arms 74 has, in a pre-assembly with the adjustment 3 connected. The annular support part 70 has an opening 700 that of one of the support part 70 above covenant 701 is surrounded (see eg 10 ).

In the embodiment according to 9A . 9B to 16 is the connection device 7 directly in the associated attachment opening 32 arranged. The connection device 7 For example, integrally and integrally made of the same material with the adjustment 3 be shaped, with the attachment arms 74 at ends 740 for example, via predetermined breaking points with the adjustment 3 are connected.

In the embodiment according to 9A . 9B to 16 is the connection device 7 detachable with the adjustment part 3 connected. The attachment arms 74 are rigidly formed such that a significant elastic resilient relative movement of the fastener 8th in the mounting hole 32 relative to the adjustment part 3 is not possible, but the fastener 8th in the pre-assembly via the mounting arms 74 rigid with the adjustment 3 connected is.

To adjust the fastener 8th relative to the adjustment 3 can provide the mounting arms 74 from its stop in the mounting hole 32 be solved so that the fastener 8th like this in 14 to 16 is shown, in the plane of extension E of the adjustment 3 inside the mounting hole 32 can be moved. This shifts the connection device 7 relative to the attachment opening 32 ,

In the pre-assembly position are the mounting arms 74 the connection device 7 about her end 740 in connection with an opening edge 320 , the fixing hole 32 surrounds (see eg 11 ). In the pre-assembly, the fastener is partially in the opening 700 the carrier part 70 screwed in (see 12A and 13 ). For mounting and adjusting the window pane 4 on the adjustment part 3 First, the fastener 8th - Analogously as above for the embodiment according to 3 to 8th has been described - in the associated counter-fastening element 52 the carrier element 5 screwed in (see 12B ). This will cause the fastener 8th with the screw head 80 in investment with the federal government 701 the carrier part 70 and thereby pushes the connection device 7 from the mounting hole 32 out. The connection between the connection device 7 and the surrounding adjustment part 3 is released in this way, so that the fastener 8th no longer about the connection device 7 in the extension plane E at the adjustment part 3 is held.

By pushing out the connecting device 7 from the mounting hole 32 arrive the attachment arms 74 the connection device 7 with ends 740 in engagement with recesses 620 at the assigned penetration point 62 of the spacer element 6 (please refer 14 and 15 ). The connection device 7 enters in this way in rotationally fixed engagement with the spacer element 6 and is thus rotationally fixed to the spacer element 6 set, so that in a (further) screwing the fastener 8th there is no turning of the connecting device 7 can come.

The window pane can - with dissolved connection device 7 - In the extension plane E relative to the adjustment 3 be adjusted, and after adjustment, the fastener 8th completely in the associated counter-fastening element 52 of the carrier element 5 be screwed in to the windowpane 4 with the adjustment part 3 to tense.

In a final assembly position (see eg 16 ) is the windowpane 4 thus on the adjustment 3 established.

In addition, the above comments on the embodiment according to 3 to 8th directed. In particular, the carrier element 5 and the spacer 6 differ in the embodiment according to 9A . 9B to 16 not from the embodiment according to 3 to 8th ,

In addition, also in the embodiment according to 9A . 9B to 16 the fastener 8th preferably in self-locking threaded engagement with the support member 70 the connection device 7 ,

In the embodiment according to 9A . 9B to 16 is the connection device 7 over the attachment arms 74 in the pre-assembly position within the mounting hole 32 established. Different variants for connecting the fastening arms 74 with the surrounding opening edge 320 the associated attachment opening 32 are conceivable and possible here.

In a first variant, shown in 17 , the connecting device can 7 for example, in one piece with the adjustment 3 be formed, wherein the connecting device 7 after the molding process from the mounting hole 32 cut out and then in turn in a clamping manner in the mounting hole 32 is used.
