Window lifter assembly with a driver for a windowpane and driver

A window lifter assembly for an adjustable windowpane of a motor vehicle, the window lifter assembly comprising:

• a guide rail;
• a driver having a connecting leg and first and second driver legs connected by said connecting leg and between said first and second driver legs is formed a receptacle gap for the adjustable windowpane, said receptacle gap including a gap base disposed between said first and second driver legs and above said connecting leg, said first driver leg being configured to mount and guide said driver on said guide rail and said second driver leg being elastically displaceable in relation to said first driver leg and has a latching element which protrudes into said receptacle gap, and when inserting the adjustable windowpane into said receptacle gap of said driver, said latching element engages in a pane-proximal latching opening of the adjustable windowpane;
• said driver further having a resting contour on which said second driver leg is supported as a result of a tensile force acting on said latching element from the adjustable windowpane in a closing direction or by a closed position of the adjustable windowpane;
• said driver having on said second driver leg a supporting contour that is spatially disposed downstream of said resting contour of said driver in a gap longitudinal direction in an insertion direction of the adjustable windowpane into said receptacle gap, between said gap base of said receptacle gap and said connecting leg;
• said supporting contour on said second driver leg being integrally molded on said second driver leg so as to be movable in relation to said resting contour in the gap longitudinal direction;
• and
• said resting contour, in the gap longitudinal direction, is disposed downstream of said latching element.
