Abstract
Official abstract text for this publication.
An air guiding device is provided at a rear end of a motor vehicle and has at least one planar air guiding element that is adjustable from a rest position into a deployed position through a first angle and that is adjustable from the rest position into a lowered position through a second angle.
First claim
Opening claim text (preview).
What is claimed is: 1. An air guiding device arranged at a rear end of a roof of a motor vehicle, the air guiding device comprising: a fixed component projecting rearward from the roof and extending laterally on the vehicle as an extension of a roof line and at least one planar air guiding element with a front end that is connected pivotally to the fixed component, the air guiding element being adjustable from a rest position where the air guiding element defines a part of the extension of the roof line into a deployed position through a first angle (α) where a rear end of the air guiding element is higher than the front end and that is adjustable from the rest position into a lowered position through a second angle (β) so that the rear end of the air guiding element is lower than the front end. 2. The air guiding device of claim 1 , wherein the at least one planar air guiding element comprises two air guiding elements arranged in a widthwise direction of the motor vehicle. 3. The air guiding device of claim 2 , wherein the two air guiding elements are jointly adjustable by one actuator unit. 4. The air guiding device of claim 1 , wherein the rear end of the air guiding element substantially aligns with a rear end of the fixed component of the air guiding device when the air guiding element is in the rest position. 5. The air guiding device of claim 1 , wherein the fixed component of the air guiding device extends laterally of the air guiding element. 6. The air guiding device of claim 5 , wherein regions of the fixed component of the air guiding device that extend laterally of the air guiding element are curved downward. 7. A motor vehicle having a rear end and a roof line extending to the rear end, and an air guiding device arranged at the rear end of the roof of the motor vehicle arranged as a continuation of the roof line at the rear end of the motor vehicle, the air guiding device comprising a fixed component projecting rearward from the roof and extending laterally on the vehicle as an extension of a roof line and at least one planar air guiding element with a front end that is connected pivotally to the fixed component, the air guiding element being adjustable from a rest position where the air guiding element defines a part of the extension of the roof line into a deployed position through a first angle (α) where a rear end of the air guiding element is higher than the front end and that is adjustable from the rest position into a lowered position through a second angle (β) so that the rear end of the air guiding element is lower than the front end. 8. The motor vehicle of claim 7 , wherein the air guiding element is adjustable in a speed-dependent manner from the rest position into the second lowered position and the air guiding element is adjustable in a sport mode from the rest position into the first deployed position. 9. The motor vehicle of claim 7 , wherein the rear end of the air guiding element substantially aligns with a rear end of the fixed component of the air guiding device when the air guiding element is in the rest position. 10. The motor vehicle of claim 7 , wherein the fixed component of the air guiding device extends laterally of the air guiding element. 11. The motor vehicle of claim 10 , wherein regions of the fixed component of the air guiding device that extend laterally of the air guiding element are curved downward.
