A window lift assembly (3) of a motor vehicle window (5) has a window pane (4) that can be divided into a first pane region (6) and a second pane region (7) in a width direction (8) of the window pane (4). A first window lift (9) carries the window pane (4) in the first pane region (6) and a second window lift (10) carries the window pane (4) in the second pane region (7). The two window lifts (9,10) are actuable independently of each other to move the window pane (4) rectilinearly up and down, to incline the window pane (4) and/or to move the window pane (4) up and down in an inclined manner.
A window lift assembly of a motor vehicle window having a window pane, wherein the window pane can be divided into at least one first pane region and into a second pane region in the width direction of the window pane, wherein a first window lift and a second window lift are provided, wherein the first window lift carries the window pane in a first pane region and the second window lift carries the window pane in a second pane region, wherein the two window lifts are actuable independently of each other in order to move the window pane rectilinearly up and down, to incline the window pane and/or to move the window pane up and down in an inclined manner.
A method for controlling air flow through a motor vehicle window having a window pane with opposite front and rear end regions provided respectively front and rear window lifts, the method comprising operating the front and rear window lifts simultaneously and in a common direction for moving the window pane rectilinearly to achieve a first air flow pattern, and operating one of the front and rear window lifts differently than the other of the front and rear window lifts to achieve slanted orientation of the window pane.

This application claims priority under 35 USC 119 to German Patent Appl. No. 10 2018 119 474.9 filed on Aug. 10, 2018, the entire disclosure of which is incorporated herein by reference.
The invention relates to a window lift assembly, in particular for a door of a motor vehicle.
Window lift assemblies for doors of motor vehicles are well known in the prior art. Earlier motor vehicles had a window pane with a manually operable mechanism in which a carriage is held movably on a rail. The carriage bears the window pane and moves together with the window pane along the rail by means of a crank and a cable pull to lower the window pane for opening the window or to raise the window pane for closing the window.
FIG. 1 is a schematic lateral partial illustration of a motor vehicle having a vehicle door with a window lift assembly according to the invention.
FIG. 1 shows part of a motor vehicle 1 having a door 2 with a window lift assembly 3 for actuating or for lifting and lowering a window pane 4 of a motor vehicle window 5.
The window pane 4 preferably is guided in the motor vehicle window 5 and is carried by the window lift assembly 3.
The window pane 4 advantageously is divided into at least one first pane region 6 and a second pane region 7 in the width direction 8 of the window pane 4.
