Abstract

A wind deflector (

5) for a motor vehicle with roof or a convertible top which can be transferred to a stowage space. The wind deflector (

5) is pivotally supported on a cross beam (

4) which extends over the front windshield (

3), and it can be pivoted by a drive (

13) which also actuates a detachable interlock of the convertible top (

2) on the cross beam (

4), depending on the position of the raising mechanism (

18) which is actuated by the drive means (

13) for the wind deflector (

5), a locking device (

11) is coupled to the drive (

13) or is uncoupled from it.

Claims

1. Arrangement for a motor vehicle with a convertible top which can be transferred to a stowage space, comprising:

2. Arrangement as claimed in claim 1, wherein a raising mechanism has a movable carriage and a raising lever which couples the carriage to the wind deflector and which sets the position of the wind deflector depending on the position of the carriage.

3. Motor vehicle wind deflector arrangement comprising a wind deflector which is pivotally supported on and is raisable by a drive device;

4. Motor vehicle wind deflector arrangement, comprising a wind deflector which is pivotally supported on and is raisable by a drive device;

5. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the carriage is movably guided essentially parallel to a pivot axis of the wind deflector.

6. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the raising lever is connected to one of the wind deflector and the carriage by a socket joint.

7. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the raising mechanism is movable to a first end position and to a second end position by the drive device and in which the wind deflector is in a closed position, and wherein intermediate positions of the raising mechanism set different pivoted-out positions of the wind deflector.

8. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the carriage is couplable to the locking mechanism by a transmission.

9. Motor vehicle wind deflector arrangement as claimed in claim 8, wherein the transmission is a lock cable; and wherein the carriage is coupled to the locking mechanism via a connectable driver depending on a direction of motion of the lock cable.

10. Motor vehicle wind deflector arrangement as claimed in claim 9, wherein the locking mechanism has a movable twist-lock which is couplable via the lock cable and the driver to the carriage.

11. Motor vehicle wind deflector arrangement as claimed in claim 10, wherein the lock cable is couplable via the driver to the carriage in two directions of motion.

12. Motor vehicle wind deflector arrangement as claimed in claim 10, wherein the twist-lock of the locking mechanism is pre-tensioned by a closing spring in a closing direction.

13. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the raising lever is movably supported on one of the raising mechanism and the carriage and is pre-tensioned via a spring means in a closing direction of the wind deflector.

14. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the drive device has a drive motor which is constructed for mounting centrally on the windshield cross beam in an installed state, and wherein the drive motor is coupled on either side via a respective drive cable to a respective raising means for the wind deflector, and wherein said raising means couples the drive motor to a respective said locking mechanism for the convertible top.

15. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the wind deflector, in a closed position, adjoins an adjustable stop element.

16. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the adjustable stop element is a rubber buffer.

17. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the wind deflector is attached to a hinge part which is adapted to be mounted to pivot around an axis extending, in an installed state, in a transverse direction of the vehicle; and wherein the raising lever is coupled to said hinge part.

18. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein the raising lever has a length which is adjustable.

19. Motor vehicle wind deflector arrangement as claimed in claim 3, wherein an actuating means is provided for setting different pivot positions of the wind deflector with the locking means opened and also closed.

20. Motor vehicle wind deflector arrangement as claimed in claim 1, wherein said actuating means is responsive to control parameters for setting said different pivot positions of the wind deflector, the control parameters being one of air noise and driving speed.

21. Motor vehicle wind deflector arrangement as claimed in claim 2, wherein the carriage is movably supported on a bearing profile rail.

22. Motor vehicle wind deflector arrangement as claimed in claim 21, wherein a drive cable and driver are supported on the bearing profile rail.

23. Motor vehicle wind deflector arrangement as claimed in claim 21, wherein a lock cable is supported on the bearing profile rail.
