Abstract

An air-guiding element for arrangement in an interior compartment, which is at least partially enclosed by windows, of a motor vehicle is provided. The air-guiding element is designed to generate a turbulent flow downstream of the air-guiding element when an air flow impinges on the air-guiding element. A motor vehicle having said air-guiding element is also described.

First claim

What is claimed:

1. An air-guiding element for arrangement in an interior compartment of a motor vehicle including a rear window and at least one air vent arranged in the interior compartment to generate an air flow in the interior compartment, the air-guiding element comprising:
a body located in the interior compartment of the vehicle and including an incident-flow region receiving the air flow from the at least one air vent and a concave flow-off region releasing a turbulent flow downstream of said air-guiding element across said rear window, wherein the incident-flow region has a straight surface that joins the concave flow-off region at a peak, wherein the air flow is in a direction of the at least one air-guiding element, and wherein the air-guiding element is proximate to or connected to the rear window.

2. The air-guiding element as claimed in claim 1 , wherein said air-guiding element is at least partially transparent.

3. The air-guiding element as claimed in claim 2 , wherein said air-guiding element has a contact surface for attachment to the rear window.

4. The air-guiding element as claimed in claim 3 , wherein said air-guiding element has a lamp.

5. The air-guiding element as claimed in claim 4 , wherein said lamp is formed as a brake lamp.

6. The air-guiding element of claim 1 , wherein said air-guiding element has a contact surface designed for attachment to the rear window.

7. The air-guiding element of claim 1 , wherein said air-guiding element has a lamp.

8. The air-guiding element of claim 7 , wherein said lamp is formed as a brake lamp.

9. The air-guiding element as claimed in claim 1 , arranged adjacent an upper region of said rear window.

10. The air-guiding element as claimed in claim 1 , arranged adjacent and along a lateral region of said rear window.

11. A motor vehicle having an interior compartment which is at least partially enclosed by a rear window and at least one vent arranged in the interior compartment, comprising at least one air-guiding element, wherein said at least one air-guiding element includes a body having an incident-flow region receiving an air flow from the at least one vent and a flow-off region releasing a turbulent flow downstream of said air-guiding element across said rear window, wherein the incident-flow region has a straight surface and the flow-off region has a concave surface that joins the straight surface at a peak, and wherein said at least one air-guiding element is arranged proximate to or connected to the rear window and adjacent an upper region of said rear window, and wherein said motor vehicle has the at least one air vent arranged in the interior compartment to generate said air flow in the interior compartment in a direction of the at least one air-guiding element.

12. The motor vehicle as claimed in claim 11 , wherein said at least one air-guiding element is arranged on a surface of the rear window facing toward the interior compartment.

13. The motor vehicle as claimed in claim 11 , wherein said at least one air-guiding element is free of the rear window.

14. The motor vehicle as claimed in claim 11 , wherein said rear window includes a heating wire.

15. The motor vehicle as claimed in claim 11 , wherein said motor vehicle is a sedan.

16. A motor vehicle having an interior compartment which is at least partially enclosed by a rear window and at least one air vent arranged in the interior compartment, comprising at least one air-guiding element, wherein said at least one air-guiding element includes a body having an incident-flow region receiving an air flow from the at least one air vent and a flow-off region releasing a turbulent flow downstream of said air-guiding element across said rear window, wherein the incident-flow region has a straight surface and the flow-off region has a concave surface that joins the straight surface at a peak, and wherein said at least one air-guiding element is proximate to or connected to the rear window and is arranged adjacent and along a lateral region of said rear window, and wherein said motor vehicle has the at least one air vent arranged in the interior compartment to generate said air flow in the interior compartment in a direction of the at least one air-guiding element.

17. The motor vehicle as claimed in claim 16 , wherein said at least one air-guiding element is arranged on a surface of the rear window facing toward the interior compartment.

18. The motor vehicle as claimed in claim 16 , wherein said at least one air-guiding element is free of the rear window.
