Air directing apparatus for a motor vehicle

1. An air-directing apparatus for a motor vehicle, comprising:

a basic body attachable to the motor vehicle and configured to direct an air flow occurring during operation of the motor vehicle as intended,

wherein the basic body has a height that changes continuously in a transverse direction of the motor vehicle,

wherein the air-directing apparatus comprises swirling elements arranged on the basic body and configured to cause swirling in the air flow,

wherein the swirling elements are spaced apart from one another in the transverse direction of the motor vehicle such that intermediate spaces are arranged between the swirling elements,

wherein the intermediate spaces expand or narrow downstream in an inflow direction of the air flow

wherein the intermediate spaces expand from a width of between one fifth and one third of the height of the basic body to a width of between 1.5 times and double the height of the basic body, or wherein the intermediate spaces narrow from a width of between 1.9 times and 2.3 times the height of the basic body to a width of between one third and one fifth of the height of the basic body.

2. The air-directing apparatus as claimed in claim 1 , wherein the swirling elements are arranged in a rear region of the basic body.

3. The air-directing apparatus as claimed in claim 1 , wherein the swirling elements are arranged on a surface of the air-directing apparatus that is directed downward or upward direction of the motor vehicle.

4. The air-directing apparatus as claimed in claim 1 , wherein the swirling elements each have a height which is at least one quarter of the height of the basic body, and/or wherein the swirling elements each have a length which is 1.5 times to 2.5 times the height of the basic body.

5. The air-directing apparatus as claimed in claim 1 , wherein the swirling elements each have a width of between 1.5 times and 2.5 times the height of the basic body.

6. The air-directing apparatus as claimed in claim 1 , wherein the swirling elements are arranged at different distances from one another, and/or wherein the swirling elements have different widths, heights and/or lengths.

7. A motor vehicle, comprising the air-directing apparatus as claimed in claim 1 , wherein the swirling elements are arranged in a projection region on the motor vehicle outside the basic body of a wing or a spoiler, wherein the projection region is defined by a vertical geometrical projection of swirling elements onto a body of the motor vehicle.

8. An air-directing apparatus for a motor vehicle, comprising:

a basic body attachable to the motor vehicle and configured to direct an air flow occurring during operation of the motor vehicle as intended,

wherein the basic body has a height that changes continuously in a transverse direction of the motor vehicle,

wherein the air-directing apparatus comprises swirling elements arranged on the basic body and configured to cause swirling in the air flow,

wherein the swirling elements are spaced apart from one another in the transverse direction of the motor vehicle such that intermediate spaces are arranged between the swirling elements,

wherein the intermediate spaces expand downstream in an inflow direction of the air flow

wherein the intermediate spaces expand continuously in a first region and have a constant width in a second region, and

wherein the second region is arranged downstream of the first region in the inflow direction of the air flow.
