Abstract

A rear air-guiding device (20) for a fastback motor vehicle (10) is arranged in the region of a roof rear edge (15) above a rear window (13) and includes an air-guiding element (22) that is movable from a rest position (30) into at least one operational position (31; 32). The rear air-guiding device has a gap sealing device that seals off a gap between a leading edge of the air-guiding element (22) and a body surface when the air-guiding device (20) is in the operational position (31; 32) and around which air would flow during driving.

Claims

1. A rear air-guiding device for a fastback motor vehicle, the air-guiding device being arranged in a region of a roof rear edge above a rear window, the rear air-guiding device comprising:

an air-guiding element that is movable between a rest position and at least one operational position, and a gap sealing device that seals off a gap between a leading edge of the air-guiding element and a body surface around which air flows during driving.

2. The rear air-guiding device of claim 1, wherein the gap sealing device also seals off a gap present in the rest position between the leading edge of the air-guiding element and the body surface around which air flows during driving.

3. The rear air-guiding device of claim 2, wherein the gap sealing device also seals off a gap present in a second operational position between the leading edge of the air-guiding element and the body surface around which air flows during driving.

4. The rear air-guiding device of claim 1, wherein the air-guiding device comprises a sealing lip that is attached to the air-guiding element in a region of the leading edge.

5. The rear air-guiding device of claim 4, wherein the sealing lip is formed from a flexible material.

6. The rear air-guiding device of claim 1, wherein the air-guiding element is a spoiler blade.

7. The rear air-guiding of claim 6, wherein the spoiler blade is an airfoil profile.

8. A fastback motor vehicle having the rear air-guiding device of claim 1.
