## Abstract

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.

## Claims

### Claim 1

A window lift assembly of a motor vehicle window having a window pane, the window pane having a first pane region and a second pane region separate from the first pane region in a width direction of the window pane, where the width direction of the window pane is transverse to a lift direction of the window pane, the window lift assembly comprising: a first window lift and a second window lift, wherein the first window lift carries the window pane in the first pane region and the second window lift carries the window pane in the second pane region, the two window lifts being actuable independently of each other to move the window pane rectilinearly up and down, to incline the window pane or to move the window pane up and down in an inclined manner.

### Claim 2 (depends on 1)

The window lift assembly of claim 1, wherein the first window lift is arranged away from the second window lift in the width direction of the window pane, and the regions of the window lifts that directly carry the window pane are spaced apart in the width direction of the window pane.

### Claim 3 (depends on 1)

The window lift assembly of claim 1, wherein the first window lift and the second window lift each have an electric drive motor.

### Claim 4 (depends on 3)

The window lift assembly of claim 3, further comprising a control unit that controls or regulates actuation of the drive motors of the first window lift and the second window lift.

### Claim 5 (depends on 1)

A vehicle door having the window lift assembly of claim 1.

### Claim 6 (depends on 5)

A motor vehicle having the vehicle door of claim 5.

### Claim 7 (depends on 1)

The window lift assembly of claim 1, wherein the width direction of the window pane extends along a travel direction of the motor vehicle.

### Claim 8 (depends on 1)

The window lift assembly of claim 1, wherein the first and second window lifts are selectively actuable in opposite directions.

### Claim 9

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: achieving a first air flow pattern through the motor vehicle window by operating the front and rear window lifts simultaneously and in a common direction for moving the window pane rectilinearly, and achieving a second air flow pattern different from the first air flow pattern by 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.

### Claim 10 (depends on 9)

The method of claim 9, further comprising operating the front and rear window lifts simultaneously and in a common direction after achieving the slanted orientation of the window pane.

### Claim 11 (depends on 10)

The method of claim 10, further comprising operating one of the front and rear window lifts differently than the other of the front and rear window lifts to achieve a rectilinear orientation of the window pane.
