Propulsion device, wind deflector and motor vehicle

A propulsion device for retracting and extending a wind deflector of a vehicle, said propulsion device comprising:

• a first guide rail extending in a longitudinal direction (X);
• a first carriage guide, which extends in the longitudinal direction (X) along the first guide rail and varies in a transverse direction (Y) that is perpendicular to the longitudinal direction (X);
• a second guide rail, which extends parallel to the first guide rail, and is spaced apart from the first guide rail in a height direction (Z) that is perpendicular to the longitudinal direction (X) and the transverse direction (Y);
• a second carriage guide, which extends in the longitudinal direction (X) along the second guide rail and varies in the transverse direction (Y);
• a pusher element for coupling with the wind deflector, said pusher element comprising a first guide element, which is configured to be adjusted in a guided manner in the first carriage guide, and a second guide element which is configured to be adjusted in a guided manner in the second carriage guide;
• and
• a cable drive for driving the pusher element relative to the guide rails, such that the pusher element moves in the longitudinal direction (X) along the guide rails, wherein the cable drive has a cable fixedly connected to the pusher element and a motor for driving the cable.
