Description

Driver for a window regulator assembly

Technical Field

The invention relates to a driver (or transmission) for a window lifter assembly for opening and closing a window opening, which driver receives an adjustable window pane of the window opening, wherein the window pane closes the window opening in the closed state and separates a vehicle interior from an exterior vehicle exterior.

Background

A different embodiment variant for connecting a window pane to a driver on a window lifter for a motor vehicle is known from the patent document DE 10 2012 208 A1.

DE 20 2012 101 871 U1 discloses a window lifter assembly for a motor vehicle, which has an adjustable window pane for closing a window opening and different embodiments of a driver connected to the window pane for adjusting the window pane. The main inventive concept of these patent documents is to improve the protection against theft, i.e. to protect the window pane against unauthorized removal. DE 20 2012 101 871 U1 proposes that the connection of the driver to the window pane is locked, so that the window pane cannot be separated from the driver by moving the latching section of the driver only by means of an actuating tool which is introduced into the installation space from the vehicle exterior and is guided close to the driver arranged as intended.

Disclosure of Invention

The object of the present invention is to provide a window lifter assembly with a comfortable catch of the type mentioned in the introduction, which reliably prevents unauthorized removal of the window pane from the window opening which is to be closed by the catch.

The starting point of the invention is a driver for a window lifter assembly for opening and closing a window opening, which driver accommodates an adjustable window pane of the window opening, wherein the window pane closes the window opening in the closed state and separates a vehicle interior from an exterior space of the vehicle which is located outside.

The driver has at least one elastically displaceable latching element with a latching lug, wherein the latching element can be displaced elastically against a restoring force (or counter to the restoring force) in order to connect the window pane to the driver on the assembly side, such that the latching lug of the latching element engages completely with a latching opening of the window pane by means of the restoring force in order to connect the window pane to the driver.

The driver is arranged in a structural space, in particular in a vehicle door, into which an operating tool can be introduced from a vehicle exterior space through a window opening via a gap between a window rail and a window pane and guided close to the driver, wherein, on the one hand, the connection of the driver to the window pane is locked (or fixed) because the latching element is arranged on the side of the window pane which is directed toward the vehicle interior space, so that, when the operating tool is introduced, the operating tool can only reach the section of the latching lug which projects into or through the latching opening of the window pane.

According to the invention, the movement of the latching element, starting from the latching element which is completely engaged in the latching opening of the window pane, is limited by a limiting element which forms an end stop for the latching element, which end stop only permits a maximum movement of the latching element, in which case, on the other hand, at least one section of the latching lug remains in the latching opening of the window pane in order to lock the window pane in the installation space even in the case of operation. The possibility of being able to remove the window pane blocked by such a catch against its intention by operation is therefore advantageously excluded by this solution.

Preferably, according to the invention, the latching element is arranged so as to be pivotable about a pivot axis, such that the latching element can be brought from an unhooked latching position, in which the latching element engages completely in the latching opening of the window pane, into a pivoted latching position, which is limited by the limiting element and only allows a maximum pivoting movement of the latching element, in which case at least the section of the latching lug remains in the latching opening of the window pane. Due to the pivotable arrangement of the catch element, the force exerted by the window pane on the pivotable catch element when the window pane is inserted does not act orthogonally (or perpendicularly) to the direction of movement of the catch element, but acts on the catch element at a smaller angle of attack, so that the forces introduced into the window pane are reduced. The assembly is thus much more comfortable, since the latching element is easier to pivot out of the insertion and guide gap provided for the window pane than a latching element which can be moved orthogonally to the window pane.

Preferably, the limiting element is arranged according to the invention on the catch base or the limiting element is the catch base itself. Since the latching element is arranged close to the driver base, this preferred embodiment is suitable for arranging the limiting element in an advantageous manner. The catch is therefore of compact design, and the limiting element can be injected (or injection molded) onto the catch base in one production step, for example, during the production of the catch base. Of course, a multi-part assembly solution between the driver base body and the limiting element is also possible.

The driver is designed as a blind mounting driver (Blindmontage-midnehmer) which preferably has a first elastically displaceable section and a second elastically displaceable section, wherein the sections are substantially opposite one another transversely to the direction of movement of the window pane, wherein in a preferred embodiment the second section is designed to be more rigid (or more rigid) than the first section. Advantageously, opposing active regions are thereby produced, which support the window pane on both sides when the window pane is introduced into the driver and when the window pane is mounted in place in the driver in a batch, so that stresses, in particular in the region of the receptacle in the driver, are avoided.

According to a first embodiment variant, it is provided that the first elastically displaceable section is a pivotable latching element which is arranged pivotably in the inner first driver web, while the second elastically displaceable section is an upper region of the outer second driver web.

According to a second embodiment variant, it is provided that the first elastically displaceable section is a pivotable detent element arranged on the carrier base, and the second elastically displaceable section is an upper region of the outer second carrier web.

Preferably, the elasticity of the upper region of the outer second catch strap of the elastically displaceable second portion is able to be predetermined (or brought about) by at least one recess in the material of the outer second catch strap. The design of the recess is a solution that can be provided with little effort and that makes it possible to adjust the necessary elasticity of the upper region of the outer second catch strap depending on the design of the recess. Different embodiment variants of the recess are explained in more detail in the description.

The elasticity of the pivotable detent element as the elastically displaceable first section is preferably able to be predetermined by a permanently elastic restoring force of the pivotable connection in the region of the pivot axis. The restoring force of the pivotable latching element is advantageously realized in the form of a film hinge, which, according to the embodiment variants, is formed in the inner first catch flap or on the catch base body according to the description.

The segments are spread apart when the window pane is inserted into the driver through the gap on the mounting side, whereby the mounting is particularly comfortable.

In particular, it is preferably provided that, after the window pane has been inserted through the intermediate space on the fitting side, the upper region of the outer second catch limb can only slightly protrude from the window pane (abs) due to its rigidity relative to the window pane by means of an actuating tool. However, it is provided that the rigidity of the outer second driver web is also so great that the outer second driver web, although yielding elastically when fitting the window pane, reacts with such great rigidity when the operating tool is introduced in the installed state of the window pane that the operating tool can only penetrate slightly, only to such an extent, into the region between the window pane and the inner side of the outer second driver web, so that the operating tool does not reach the latching element or reaches it only with a very high expenditure of force. In order to increase the force consumption as much as possible, it is provided that, in the event of an insertion of the actuating tool between the window pane and the upper region of the outer second driver web, the extension and/or breaking of the outer second driver web relative to the inner first driver web is influenced in that a mechanically stabilizing insert is arranged in a driver web base (or bottom) in which the driver webs are connected to one another. Such an insert, in particular a steel insert, which increases the stability of the outer second driver web in the region of the connection to the outer first driver web, is a measure that can be taken into account in an advantageous manner in the production of the driver.

Detailed Description

Fig. 1 shows an external view YA (without an external door panel) of a motor vehicle door 100 arranged in the longitudinal direction x of the motor vehicle, with a window lifter assembly 10 according to the invention without a window pane which is inserted in the assembled state in the driver 1 spaced in the x direction. The paired arrangement in the upper region corresponds to a closed window pane and the lower position of the driver 1 corresponds to a half-open or open window pane. Fig. 1 shows an exterior view YA of one or more drivers 1 in the assembled state, as seen from the vehicle exterior a looking into the motor vehicle door 100.

The connection between driver 1 and window pane, which prevents an undesired detachment of the window pane from driver 1 by means of an operating tool, is optimized by drivers 1A (first embodiment variant) and 1B (second embodiment variant) which are described in the embodiment variants.

The component denoted by the stem 1A.. Belongs to the catch 1A according to the first embodiment variant, while the component denoted by the stem 1B.. Belongs to the catch 1B according to the second embodiment variant.

Fig. 2 to 6 are considered together below, fig. 2 to 4 showing a first embodiment variant and fig. 5 and 6 showing a second embodiment variant.

Two variants of embodiment-drivers 1A and 1B:

when the window pane F is installed as intended, the window pane F and the driver 1 can only be contacted via the gap S in the window opening. This is usually an outer groove in a door rail of the motor vehicle door 100, through which an opening window pane can be lowered into the motor vehicle door 100 in order to open the window opening.

In the installed state of the window lifter assembly and the window pane F in the motor vehicle, the closed window pane F separates the vehicle interior space I from the vehicle exterior space a located outside the motor vehicle. In the following, the window regulator assembly and the window pane as well as the driver elements 1A, 1B are shown in an interior view by YI (see subsequent figures).

The drivers 1A, 1B are designed as blind-mounted drivers, which according to the invention have a first elastically displaceable section A1 and a second elastically displaceable section A2.

According to the invention, the second section A2, although likewise elastically movable like the first elastic section A1, is less elastic, i.e. stiffer than the first elastic section A1.

That is to say, blind fitting of the window pane F, in particular in the motor vehicle door 100, is possible by inserting the window pane F (see fig. 3 and 6) through the window opening (gap S, fig. 1) into the motor vehicle door 100 and lowering it to such an extent that the lower edge of the window pane F rests on the base-side carrier webs 1a.4, 1b.4 of the bases 1a.6, 1b.6 of the drivers 1A, 1B.

In this process, according to the invention, the sections A1, A2 of the driver 1A, 1B, which are situated opposite one another in a manner that is elastically transverse to the direction of movement of the window pane F, the first elastically movable section A1 and the second elastically movable section A2 move, the second section A2 being designed to be stiffer than the first section A1.

The drivers 1A, 1B form receiving grooves 1a.1, 1b.1, which are formed by two driver webs 1a.2, 1a.3 and 1b.2 and 1b.3, respectively. The driver webs 1a.2, 1a.3 and 1b.2 and 1b.3 form a common elastic driver web base 1a.5, 1b.5.

Transversely to the web webs of the driver webs 1a.2, 1a.3 and 1b.2 and 1b.3, support webs 1a.4, 1b.4 are arranged between the driver webs 1a.2, 1a.3 and 1b.2 and 1b.3, on which the window pane F rests in the installed state.

The driver webs 1a.2, 1a.3 and 1b.2, 1b.3 and the driver bases 1a.6, 1b.6 are connected to one another in one piece or in two pieces. The support webs 1a.4, 1b.4 are arranged in the base bodies 1a.5,1b.5 and, as explained, are situated orthogonally in the receiving grooves 1a.1, 1b.1 in a predefinable position. The width of the respective accommodating grooves 1a.1, 1b.1 is substantially equal to the width of the window pane F.

First embodiment — driver 1A:

the latching element 1a.r is arranged in the inner first driver web 1a.2 so as to be pivotable on the pivot axis X1. In other words, the detent element 1a.r is arranged on the side of the window pane F facing the vehicle interior I when the driver 1A is arranged as intended in the installation space of the motor vehicle door 100.

That is, the detent element 1a.r can only be actuated from the outside a to such an extent that a section 1a.r1 of the detent lug, which in the assembled state projects through the detent opening F1 (see fig. 4) of the window pane F, can be influenced by the actuating tool. However, the section 1a.r1 of the detent lug projecting through the window pane F cannot disengage the detent element 1a.r from the detent opening F1 of the window pane F.

The detent element 1a.r is arranged in the inner first driver web 1a.2 in such a way that the pivot axis X1 is arranged above the detent element 1a.r of the inner first driver web 1a.2.

The detent element 1a.r has a mounting ramp 1a.r2 which starts substantially below the pivot axis X1 and (in the initial position in the undeflected state of the detent element 1a.r) extends substantially to the inside of the outer second catch web 1a.3, so that the detent element 1a.r extends substantially over the entire width of the receiving groove 1a.1.

In the region of the latching element 1a.r, the outer second driver web 1a.3 has a recess 1a.31 which increases the elasticity of the outer second driver web 1a.3 in the upper region of the outer second driver web 1a.3, so that the installation of the window pane F is optimized, i.e., more comfortable, as will be explained.

The recess 1a.31 is formed in the outer second driver web 1a.3 at the upper end of the outer second driver web 1a.3 in an upwardly open "U" shape, and thus forms in a simple manner, in particular in the region of the lateral webs of the "U", an elastic region of the outer second driver web 1a.3.

From the above description, it is stated in accordance with the first embodiment variant of the driver 1A that the first elastically displaceable section A1 according to the invention is a pivotable catch element 1a.r arranged in the inner first driver web 1a.2, and that the second elastically displaceable section A2, which is stiffer than the first section A1, according to the invention is an upper region of the outer second driver web 1a.3.

The advantage of the solution according to the invention is the combination of simplified assembly of the window pane F and increased security against theft of the window pane F.

The window pane 1 is assembled by guiding the window pane 1 into a receiving groove 1a.1 of the motor vehicle door 100 formed by the driver cleats 1a.2, 1a.3.

The lower edge of the window pane F strikes the assembly ramp 1a.r2 of the catch element 1a.r. The window pane F slightly collides with the inside of the second, outer driver bridge 1a.3, so that the two driver bridges 1a.2, 1a.3 diverge.

In a similar manner to the outer second driver web 1a.3, the inner first driver web 1a.2 is also designed to be elastic in the upper region.

However, the elasticity of the two driver webs 1a.2, 1a.3 is less than the elasticity of the more flexible, more elastic latching elements 1a.r due to the pivotable arrangement.

This solution provides as large a free space as possible for assembly between the inner sides of the catch webs 1a.2, 1a.3 and the inner sides of the latching elements 1a.r, i.e. the accommodating groove 1a.1 widens in the upper region, so that the bending load on the window pane F is reduced.

The window pane F then collides with the catch element 1a.r, which pivots about the pivot axis X1, so that the catch opening F1 of the window pane F engages in the catch element head of the catch element 1a.r as soon as the catch opening F1 of the window pane F is guided into the region of the catch element head of the catch element 1a.r.

Finally, the window pane F is supported on the carrier strip 1a.4. Starting from the home position shown in fig. 2, the detent element 1a.r automatically returns to its detent position, which corresponds to the home position, in accordance with fig. 4 after pivoting about the pivot axis X2.

The spread driver jaws 1a.2, 1a.3 likewise return to their original non-spread position and hold the window pane F. The fitting can thus advantageously be carried out optimally and comfortably with reduced bending loads acting on the window pane 1.

In terms of the security against theft of the window pane F, the following is shown (see fig. 3 and 4 in particular). Since the window pane F is now fitted, the elastic region of the inner first driver web 1a.2 cannot be touched from the vehicle exterior space a and therefore cannot be elastically deflected by the actuating means, so that the one of the driver webs 1a.2, on which the latching element 1a.r is arranged, cannot be directly deflected. The section 1a. R1 of the latching lug which projects through the latching opening F1 (see fig. 4) of the window pane F is only slightly influenced by the operating tool. According to the illustration in fig. 3, even for the pivoting detent element 1a.r', a section 1a.r1 of the detent lug of the detent element 1a.r always remains in the detent opening F1 of the window pane F.

In order to prevent any possible particularly adapted actuating means from effecting a pivoting movement about the pivot axis X1 to the extent that the detent element 1a.r is disengaged from the detent opening F1, in order to further increase the security against theft, a limiting element 1a.61 (see fig. 3) is arranged as an end stop on the catch base 1a.6, which limiting element limits the pivoting movement of the detent element 1a.r about the pivot axis X1. In other words, in the operating situation, the catch element 1a.r can be pivoted into a maximum pivot position of the catch element 1a.r', in which, however, at least one section 1a.r1 of the catch lug projecting into the window pane F remains reliably in the catch opening F1, so that removal of the window pane F is advantageously completely avoided.

In order to make handling generally more difficult, it is also ensured that the outer second driver strap 1a.3 itself cannot be spread apart at the driver strap base 1a.5 or be destroyed by using increased force. An insert 1a.51, in particular a steel insert, which serves to stabilize the driver bridge 1a.2, 1a.3 against being spread apart or broken off, which can be injection molded during production, is arranged in the driver bridge base 1a.5. The force required for opening or prying off the accommodation groove 1a.1 is advantageously increased by this measure, so that possible operations are effectively resisted.

Second embodiment — driver 1B:

the detent element 1b.r is arranged pivotably on the driver base 1b.6 on the pivot axis X2. In other words, the detent element 1a.r is arranged on the side of the window pane F facing the vehicle interior I when the driver 1B is arranged as intended in the installation space of the motor vehicle door 100.

That is, the detent element 1b.r can only be actuated from the outside a to such an extent that a section 1b.r1 of the detent lug which projects through the detent opening F1 (see fig. 6) of the window pane F in the assembled state can be influenced by the actuating tool. However, the section 1b.r1 of the latching lug projecting through the window pane F cannot disengage the latching element 1b.r from the latching opening F1 of the window pane F.

The detent element 1b.r is arranged on the driver base 1b.1 in such a way that the pivot axis X2 is arranged below the detent element 1b.r.

The detent element 1b.r has an assembly ramp 1b.r2 which begins at the upper end of the detent element 1b.r and (in the initial position in the undeflected state of the detent element 1b.r) extends substantially to the inside of the outer second driver web 1b.3 (see fig. 5), so that the detent element 1b.r extends substantially over the entire width of the receiving groove 1b.1.

In the region of the latching element 1b.r, the outer second catch web 1b.3 has a recess 1b.31 which increases the elasticity of the outer second catch web 1b.3 in the upper region of the outer second catch web 1a.3, so that the installation of the window pane F is optimized, i.e., more comfortable, as will also be explained.

The recess 1b.31 is formed in the outer second catch web 1a.3 at the upper end of the outer second catch web 1a.3 as a through-hole and thus forms in a simple manner, in particular in the upper region, an elastic region of the outer second catch web 1b.3, wherein the elasticity of the pivotably arranged latching element 1b.r is greater than the elasticity of the outer second catch web 1b.3.

From the above description, it is stated in accordance with the second embodiment variant of the driver 1B that the first elastically displaceable section A1 according to the invention is a pivotable detent element 1b.r arranged on the driver base body 1b.6 and the second elastically displaceable section A2 according to the invention is an upper region of the second outer driver web 1b.3, wherein it is also provided that the second elastically displaceable section A2 of the upper region of the second outer driver web 1b.3 is designed to be stiffer than the pivotable detent element 1b.r.

Alternatively, a pivotable detent element 1b.r arranged on the driver base 1b.6 can also be arranged in the inner first driver web 1b.2, similarly to the first embodiment variant.

The window pane 1 is assembled by guiding the window pane 1 into a receiving groove 1b.1 of the motor vehicle door 100 formed by the driver cleats 1b.2, 1b.3.

The lower edge of the window pane F strikes the assembly ramp 1b.r2 of the catch element 1b.r. In this case, the window pane F slightly collides with the inside of the outer second driver web 1b.3, so that the outer second driver web 1a.3 and the catch element 1b.r are spread apart.

As soon as the lower edge of the window pane F passes the detent element 1b.r and the lower edge of the window pane F is pushed into the region of the inner first driver web 1a.2, the inner first driver web 1a.2 takes over the guidance of the window pane F.

This solution provides as large a free space as possible for assembly between the inner side of the driver web 1b.3 and the inner side of the detent element 1b.r, i.e. the receiving groove 1b.1 widens in the upper region, so that the bending load on the window pane F is reduced.

As explained, the window pane F collides with the catch element 1b.r, which pivots about the pivot axis X2, so that the catch opening F1 of the window pane F engages in the catch element head of the catch element 1b.r as soon as the catch opening F1 of the window pane F is guided into the region of the catch element head of the catch element 1b.r.

Finally, the window pane F is supported on the carrier strip 1b.4. Starting from the home position shown in fig. 5, the detent element 1b.r automatically returns to its detent position, which corresponds to the home position in fig. 5, after pivoting about the pivot axis X2 (see reference numeral 1b.r' in fig. 6) as shown in fig. 6.

Thus, the divergent catch strap 1b.3 and the catch element 1b.r return to their original non-divergent position and hold the window pane F. The fitting can thus advantageously be carried out optimally and comfortably with reduced bending loads acting on the window pane 1.

In terms of the security against theft of the window pane F, the following is shown (see fig. 5 and 6 in particular). As a result of the now fitted window pane F, the spring region of the catch element 1b.r cannot be reached from the vehicle exterior a and therefore cannot be deflected elastically by the actuating means.

The section 1b. R1 projecting through the catch opening F1 (see fig. 4) of the window pane F is only slightly influenced by the operating tool. According to the illustration in fig. 6, even for the pivoting catch element 1b.r', a section 1b.r1 of the catch element 1b.r always remains in the catch opening F1 of the window pane F.

In order to make it absolutely impossible to execute a pivoting movement of the detent element 1b.r about the pivot axis X2 by means of a possibly specially adapted operating tool to such an extent that the detent element 1b.r is disengaged from the detent opening F1, in order to further increase the security against theft, according to the invention a limiting element 1b.61 (see fig. 5 and 6) is arranged on the catch base 1a.6, which limiting element limits the pivoting movement of the detent element 1b.r about the pivot axis X2 as an end stop. In other words, in the operating situation, the catch element 1b.r can be pivoted into a maximum pivot position of the catch element 1b.r', but in this maximum pivot position at least one section 1b.r1 projecting into the window pane F remains reliably in the catch opening F1, so that removal of the window pane F is advantageously completely avoided.

In order to make handling generally more difficult, it is also ensured that the outer second driver strap 1b.3 itself cannot be spread apart at the driver strap base 1b.5 or be destroyed by using increased force. An insert 1b.51 (see fig. 5), in particular a steel insert, is arranged in the driver web base 1b.5, which serves to stabilize the driver webs 1b.2, 1b.3 against spreading or breaking, and which can be injection molded during production. The force required for breaking or prying open the accommodation groove 1b.1 is advantageously increased by this measure, so that possible operations are effectively resisted.

A driver (1) for a window lifter assembly for opening and closing a window opening, which driver accommodates an adjustable window pane (F) of the window opening, wherein the window pane (F) in the closed state closes the window opening and separates a vehicle interior (I) from a vehicle exterior (a) lying outside, wherein the driver (1 a, 1B) has at least one elastically movable latching element (1a.r, 1b.r) having latching lugs, wherein, for connecting the window pane (F) to the driver (1 a, 1B) on the assembly side, the latching element (1a.r, 1b.r) is elastically movable against a restoring force, so that the latching lugs of the latching element (1a.r.r) are brought into engagement with the latching opening (F1) of the window pane (F) by the restoring force, in order to bring the driver (1) into engagement with the window opening (1) and to bring the driver (1) into engagement with the window opening (1 a, 1B) via a gap, wherein the driver (1 a, 1B) is arranged between the window pane (a, 1a window opening, 1B) and the driver (1, 1B), since the catch element (1a.r, 1b.r) is arranged on the side of the window pane (F) pointing toward the vehicle interior (I), the actuating tool can only reach the section (1a.r 1, 1b.r 1) of the catch lug protruding into or through the catch opening (F1) of the window pane (F) when the actuating tool is inserted, characterized in that the movement of the catch element (1a.r, 1b.r) starting from the catch element (1a.r, 1b.r) completely engaging in the catch opening (F1) of the window pane (F) is limited by a limiting element (1a.61, 1b.61) which forms an end stop for the catch element (1a.r, 1b.r) which permits only a maximum movement of the catch element (1a.r, 1b.r) in which, on the other hand, at least one catch element (1a.r, 1b.r) remains in the catch opening (1) of the window pane (F) in order to lock the window pane (F) in the catch opening (1).

2. The driver (1, 1a, 1B) as claimed in claim 1, characterized in that the detent element (1a. R, 1b. R) is pivotably arranged about a pivot axis (X1, X2) such that the detent element (1a. R, 1b. R) can be brought into a pivoted detent position from an unhooked detent position, in which the detent element (1a. R, 1b. R) completely engages in the detent opening (F1) of the window pane (F), which is limited by the limiting element (1a.61, 1b.61) and only allows a maximum pivoting movement of the detent element (1a.r, 1b.r), in which case at least the section (1a.r 1, 1b.r 1) of the detent lug remains in the detent opening (F1) of the window pane (F).

3. The driver (1, 1a, 1B) as claimed in claim 1, characterised in that the limiting element (1a.61, 1b.61) is arranged on the driver base (1a.6, 1b.6) or on the driver base (1a.6, 1b.6) itself.

4. The driver (1, 1a, 1B) as claimed in claim 1 or 2, characterized in that the driver (1, 1a, 1B) is designed as a blind-fit driver having a first elastically movable section (A1) and a second elastically movable section (A2), wherein the first section (A1) and the second section (A2) are substantially opposite one another transversely to the direction of movement of the window pane (F), wherein the second section (A2) is designed to be more rigid than the first section (A1), and wherein the second section (A2) is designed to be more rigid than the first section (A1)

The elastically displaceable first section (A1) is a pivotable catch element (1A.R) which is arranged pivotably in an inner first driver web (1A.2) and the elastically displaceable second section (A2) is an upper region of an outer second driver web (1A.3)

The first elastically displaceable section (A1) is a pivotable detent element (1B.R) arranged on the driver base body (1B.6), and the second elastically displaceable section (A2) is an upper region of the outer second driver web (1B.3).

5. The driver (1, 1A, 1B) as claimed in claim 4, characterised in that the elasticity of the upper region of the outer second driver web (1A.3, 1B.3) of the elastically displaceable second section (A2) is able to be predetermined by means of at least one recess (1A.31, 1B.31) in the material of the outer second driver web (1A.3, 1B.3).

6. The driver (1, 1A, 1B) as claimed in claim 4, characterized in that the resilience of the pivotable catch element (1A.R) as the resiliently displaceable first portion (A1) is able to be predetermined by means of a permanently resilient restoring force of the pivotable connection in the region of the pivot axis (X1, X2).

7. The driver (1, 1A, 1B) as claimed in claim 6, characterized in that the first and second sections (A1, A2) are spread apart when the window pane (F) is introduced into the driver (1.

8. The driver (1, 1A, 1B) as claimed in claim 6, characterised in that, after the window pane (F) has been introduced on the fitting side through the gap (S), the upper region of the outer second driver web (1A.3, 1B.3) can only slightly protrude from the window pane (F) by means of the actuating tool due to its rigidity relative to the window pane (F).

9. The driver (1, 1a, 1B) as claimed in claim 8, characterized in that, when the actuating tool is introduced between the window pane (F) and the upper region of the outer second driver web (1a.3, 1b.3), the extension and/or the fracture of the outer second driver web (1a.3, 1b.3) relative to the inner first driver web (1a.2, 1b.2) is influenced in that a mechanically stabilizing insert (1a.51, 1b.51) is arranged in the driver web base (1a.5, 1b.5), in which the outer second driver web (1a.3, 1b.3) and the inner first driver web (1a.2, 1b.2) are connected to one another.
