Abstract

A window lifter assembly includes a window pane which includes a connecting portion to which an adapter is molded, the adapter thereby being an integral part of the window pane, the adapter forming a driver element for moving the window pane along an adjustment direction and forming a supporting structure which extends in the adjustment direction and in a transverse direction and running generally perpendicular to the adjustment direction and parallel to a pane plane defined by the window pane, wherein an extension of the supporting structure along the transverse direction is at least twice as large as an extension of the driver element along the transverse direction.

First claim

The invention claimed is:

1. A window lifter assembly, comprising:
at least one guide rail extending along an adjustment direction,
a window pane configured to be moved along the adjustment direction,
a flexible cable for transmitting an adjusting force for adjusting the window pane,
a driver element which is connected with the cable; and
a sliding element connected with the driver element and being shiftably mounted on the at least one guide rail so that the driver element connected to the sliding element is adjustable along the at least one guide rail,
wherein the window pane has a generally linear lower edge and two side edges, the window pane including a connecting portion extending away from the lower edge to which an adapter is molded, the adapter and the window pane thereby being an integral unitary one-piece component,
wherein the adapter includes the driver element and includes a supporting structure, the supporting structure being configured to extend in the adjustment direction and in a transverse direction running generally perpendicular to the adjustment direction and substantially parallel to a pane plane defined by the window pane, and
wherein an extension of the supporting structure along the transverse direction is at least twice as large as an extension of the driver element along the transverse direction.

2. The window lifter assembly according to claim 1 , wherein the supporting structure is adjacent the lower edge of the window pane and extends along an entire length of the lower edge of the window pane.

3. The window lifter assembly according to claim 1 , wherein the supporting structure tapers towards the driver element.

4. The window lifter assembly according to claim 1 , wherein the supporting structure forms a rib structure.

5. The window lifter assembly according to claim 4 , wherein the rib structure extends along the lower edge of the window pane with a first length and the driver element extends along the lower edge of the window pane with a second length, the first length being at least twice as large as the second length.

6. The window lifter assembly according to claim 1 , wherein the connecting portion of the window pane protrudes from the lower edge of the window pane.

7. The window lifter assembly according to claim 1 , wherein the window pane is at least partly made of a plastic material and the adapter is injection-molded to the plastic material of the window pane.

8. The window lifter assembly according to claim 1 , wherein the adapter includes a manipulation protection element which is configured to block movement of a manipulation tool guided along the window pane.

9. The window lifter assembly according to claim 8 , wherein at least a portion of the manipulation protection element extends at an angle to the pane plane.

10. The window lifter assembly according to claim 8 , wherein the adapter is integral with the manipulation protection element.

11. The window lifter assembly according to claim 8 , wherein at least a portion of the manipulation protection element extends substantially perpendicularly to the pane plane.

12. The window lifter assembly according to claim 1 , wherein the supporting structure is adjacent the lower edge of the window pane and extends over a majority of a width of the window pane.
