2 Fig. 1 shows a driver of a window lifter, is attachable to the window glass by means of a holder 3. The driver 2 can, for example, be connected to the drive of the window lifter via a rope (not shown in more detail).

Fig. 2 shows a section along the section line AA of Fig. 1. In this illustration it can be clearly seen that the driver 2 has two recesses 21 , in the 3 formed on the holder pins 39 engage positively. The window pane 1 has a hole 11 into which the holder 3 is inserted.

The holder 3 is elastic and is provided with a funnel-shaped opening 35 on its side facing the driver 2 . In this opening, a Innenge thread 36 is formed, in which a hexagon screw 33 is screwed to spread the bracket 3 .

Another embodiment is shown in FIG. 3. There, the bracket 3 is positively edged in the driver 2 . In addition, the driver 2 is provided with recesses 21 , which engage with the bracket 3 connected hooks 390 positively. The holder 3 has a flange 31 and projecting, expandable hooks 32 . The hooks 32 protrude from the hole 11 in the window pane 1 and can be spread by means of the screw 33 in such a way that, as indicated by the dash-dotted lines, they encompass the window pane 1 .

The screw 33 is preferably provided with a self-cutting thread which, depending on the spread resistance, the hook 32 of the holder 3 cuts more or less deeply into it.

In the contact area of the hole 11 of the window pane 1 , the holder 3 is provided with an elastomer coating 5 , which comes into contact with the spread of the holder 3 on the inner wall and the outer edges of the hole 11 . The holding tion 3 in turn has an internal thread 36 along which the screw 33 is axially adjustable. The maximum spread of the bracket 3 is always determined by the thread diameter of the screw 33 .

FIG. 4 shows a sectional illustration of the holder according to FIG. 3 along the section line BB. The hooks 32 of the holder are in the unspread starting position, so that there is still a gap between the holder and the hole 11 . Furthermore, the hooks 390 of the holder inserted into the recesses 21 of the driver can be seen.

The holder 3 shown in FIG. 5 can in turn be expanded by means of a screw 33 . The holder 3 consists of a flat flange 31 with projecting, expandable hooks 32 which protrude from the hole 11 of a window pane 1 .

An elastomer coating 5 is framed in the holder 3 in such a way that the latter forms, with the hooks 32, a bolt 41 having a gap 40 . This bolt can be inserted into the hole 11 of the window pane 1 with play in the unspread state.

The elastomer coating 5 is arranged in the area of the flange 31 of the bracket 3 in parallel, so that there is a flat contact surface opposite the window pane 1 , which ensures a uniform loading of the window pane 1 in the area of the bracket 3 . Furthermore, an annular groove 51 is formed in the elastomer coating 5 at the transition between the flange 31 and the bolt 41, which prevents the elastomer coating 5 from bulging and thus prevents an uneven loading of the window pane 1 when the hooks 32 are spread .

FIG. 6 shows a front view of the holder 3 according to FIG. 5. A funnel-shaped opening 35 is formed in the holder 3 , which facilitates the insertion of the screw 33 into the gap 40 . 3 elongated holes 42 are formed within the holder at right angles to the gap 40 .

These elongated holes 42 are used to fasten the elastomer coating 5 , which, as can be seen in FIG. 1, are provided with pins 51 engaging in the elongated holes 42 . The right-angled arrangement of the elongated holes 42 with respect to the gap 40 ensures that the pins 51 are displaceable relative to the holder 3 when the hooks 32 are spread. This configuration prevents bulging of the flange-like area of the elastomer coating 5 .

As in the exemplary embodiment described above, the holder 3 in turn has elastic hooks 390 , which enable a positive and / or non-positive connection of the holder 3 to the driver 2 according to FIG. 5.

FIG. 7 shows a rear view of the holder 3 shown in FIGS. 5 and 6. It can be clearly seen that the hooks separated from one another by the gap 40 have an approximately semicircular end face. Behind this end face, the hooks have shoulders adjacent to the dashed line, into which the elastomer coating is framed like a sleeve.

Furthermore, the elongated holes 42 for fastening the elastomer coating to the just-formed flange 31 of the holder 3 can also be seen in FIG. 7. The gap 40 running at right angles to the elongated holes 42 is widened in an oval shape in the center of the holder 3 . This extension serves to guide the screw during the spreading of the hooks 32 . The screw is, according to FIG. Screwed into the internal threads provided with a carrier 2 5.

In the exemplary embodiment shown in FIG. 8, the hooks 32 of the holder 3 are spread out by means of a lockable bolt 34 . The bracket 3 is positively placed on the tube 22 expanded in the region of its opening with participants 2 .

The upper half of FIG. 8 shows how the hooks 32 of the holder are first inserted into the hole 11 in the window pane with play. The just formed flange 31 of the holder 3 lies flat on the side surface of the window pane 1 .

The bolt 34 has two beveled hooks 342 in the direction of insertion, which, as shown in the lower half of FIG. 8, spread apart the hooks 32 of the holder 3 when the bolt 34 is inserted and finally hooks on the front side of the hooks 32 .

The elastomer coating 5 , which is framed on the hook 32 , is pressed against the inner wall and the left outer edge of the hole 11 of the window pane 1 in a form-fitting manner. A sheet 6 is preferably enclosed in the hook 32 , which serves to reinforce the hook 32 and as a sliding surface for the elastomer coating 5 during the spreading of the hook 32 .

At the bolt 34, a flange 341 is further formed, which limits the insertion movement of the bolt 34, and thereby takes a form fit on the driver 2 to the system.

In Fig. 9, the position of the hook 32 is shown with respect to the hole edge of the window pane. In the lower half of the figure it can clearly be seen how the spread hook 32 engages around the perforated edge of the window pane. It can also be seen how the locked hook 342 of the bolt engages behind the end face of the spread hook 32 .

As is also shown in FIG. 9, the holder preferably has guide grooves 37 which engage in the longitudinal webs 38 formed on the bolt. In this way, twisting of the bolt is prevented, for example as a result of vibrations, and thus a permanently secure connection of the window pane to the driver is ensured.

Another preferred exemplary embodiment is shown in FIGS. 10 to 12. In this game Ausführungsbei the bracket 3 and the lockable bolt are made of plastic together, the bolt being cast on the bracket in the region of its beveled hook 342 and detachable from it with little force.

The driver 2 has an oval-shaped opening 22 for fastening the bolt 34 , into which the bolt 34 can be inserted with its flange 341, which is also oval in shape, when it is rotated accordingly. After the holder 3 has been rotated by 90 ° about the longitudinal axis of the cast-on bolt 34 , the holder 3 can be positively connected to the driver 2 .

The bolt 34 cast onto the holder can then be sheared off from the holder, for example by a rotary movement, and inserted in the released state in order to spread the hooks 32 . The oval flange 341 limits the insertion depth of the Bol zens 34 , which is locked in the end position by means of its beveled hook 342 on the hook 32 of the bracket 3 .

The bolt 34 also has a flattened area 343 which, after the bolt has been locked, is in a form-fitting manner against the inner wall of the gap opening between the hooks 32 . This configuration prevents subsequent rotation of the bolt 34 ver.

The invention is not limited in its execution the preferred embodiments given above games. Rather, a number of variants are conceivable which of the solution shown also in principle use different types of designs. In particular the invention is not limited to the connection only a window pane with the driver of a motor vehicle Window lifter.
