## Abstract

A driver for a movable window pane, in particular of a motor vehicle, having a receptacle recess, a receptacle of an edge section of the window pane, and having an elastically displaceable detent lug which is designed to engage in a latching cutout of the window pane in order to arrest the window pane on the driver, wherein the detent lug, in the reset position thereof, obstructs the receptacle recess and has an insertion taper assigned to the receptacle recess such that the detent lug is displaced into a position releasing the receptacle recess by insertion of the window pane into the receptacle recess. The detent lug has a catch groove on the insertion taper which extends parallel to the receptacle recess over the detent lug.

## Claims

### Claim 1

A driver for a movable window pane of a motor vehicle, comprising:
a receptacle recess for receiving an edge section of the window pane;
an elastically displaceable detent lug adapted to engage with a latching cutout of the window pane for locking the window pane on the driver, the detent lug obstructing the receptacle recess in an initial position; and
wherein the detent lug has an insertion taper so that the detent lug is displaced out of the receptacle recess by an insertion of the window pane into the receptacle recess,
wherein the detent lug has a catch groove in the insertion taper that extends substantially parallel to the receptacle recess over the entire width of the detent lug,
wherein the catch groove is arranged in the latching cutout of the window pane when the window pane is inserted into the receptacle recess, and
wherein the insertion taper has an upper first guiding section and a lower second guiding section that have an inclined orientation to each other, wherein the catch groove is situated between the upper first guiding section and the lower second guiding section and wherein an upper edge of the latching cutout of the window pane directly contacts the upper first guiding section of the insertion taper when the window pane is inserted into the receptacle recess and the detent lug is in the initial position.

### Claim 2 (depends on 1)

The driver according to claim 1, wherein the catch groove is narrower than the receptacle recess or narrower than the window pane.

### Claim 3 (depends on 1)

The driver according to claim 1, wherein the catch groove is situated between the upper first guiding section and the lower second guiding section.

### Claim 4 (depends on 1)

The driver according to claim 1, wherein at least one side wall of the catch groove is oriented at least essentially perpendicularly to a base of the catch groove.

### Claim 5 (depends on 1)

A window pane arrangement for a motor vehicle, comprising the movable window pane and the driver according to claim 1.

### Claim 6 (depends on 5)

The window pane arrangement according to claim 5, wherein the window pane has at least one insertion chamfer on its edge facing the driver.

### Claim 7 (depends on 6)

The window pane arrangement according to claim 6, wherein the insertion chamfer bridges the catch groove of the detent lug when the window pane is inserted into the receptacle recess.

### Claim 8 (depends on 1)

The driver according to claim 1, wherein the catch groove has a base, a first side wall that extends from and is directly connected to a first edge of the base and a second side wall that extends from and is directly connected to a second edge of the base, wherein the second side wall and the first side wall oppose one another and are each oriented perpendicular to the base.
