Folding roof arrangement with elastically deformable tensioning elements pivotally attached to a support structure of a vehicle

1. A folding roof arrangement for a vehicle having a windshield frame, comprising:

a folding top structure having roof frame side parts hinged to the vehicle rearward of the windshield frame and a roof frame front part extending between the roof frame side parts, the roof frame side parts of the folding top structure being foldable between and open position where the roof frame front part is rearward of the windshield frame and a closed position where the roof frame front part is in proximity to the windshield frame;

a plurality of elastically deformable tensioning elements, each of the elastically deformable tensioning elements having a front longitudinal end attached to the roof frame front part of the folding top structure at a front joint and a rear longitudinal end attached to a support structure of the vehicle at a rear joint, at least one of the front and rear joints of each of the elastically deformable tensioning elements being configured to pivot about a pivot axis; and

a folding top covering disposed on the folding top structure and the elastically deformable tensioning elements.

2. The folding roof arrangement of claim 1 , wherein the elastically deformable tensioning elements are deformed elastically when the folding top structure is folded.

3. The folding roof arrangement of claim 1 , wherein at least one of the elastically deformable tensioning elements of the folding top structure is configured for linking to the vehicle.

4. The folding roof arrangement of claim 1 , further comprising an elastically deformable tensioning elements of the folding top structure that defines a folding top bow.

5. The folding roof arrangement of claim 1 , wherein at least one of the elastically deformable tensioning elements is pre-tensioned.

6. The folding roof arrangement of claim 5 , wherein the elastically deformable tensioning element is pre-tensioned so that a closing movement of the folding top structure is assisted by a pre-tensioning force of the elastically deformable tensioning element.

7. The folding roof arrangement of claim 1 , wherein at least one of the elastically deformable tensioning elements extends, at least in part, in a longitudinal direction from the roof frame front part of the roof frame to a rear area of the roof arrangement.

8. The folding roof arrangement of claim 1 , wherein at least one of the elastically deformable tensioning elements extends, at least in part, diagonally from the roof frame front part of the roof frame to a rear area of the roof arrangement.

9. The folding roof arrangement of claim 1 , wherein the elastically deformable tensioning elements are curved when the folding top structure is in the open position or in the closed position.

10. The folding roof arrangement of claim 1 , wherein the front joints are provided at plural points on the roof frame front part.

11. The folding roof arrangement of claim 10 , wherein the pivot axes of the front joints on the roof frame front part are inclined in relation to a Z axis that is substantially perpendicular to an X axis extending rearward from the roof frame front part and substantially perpendicular to a Y axis that extends between the roof frame side parts, so that under a folding movement of the folding roof arrangement the tensioning elements perform a defined movement or are definably deformed.

12. The folding roof arrangement of claim 1 , wherein the roof frame comprises two roof frame side parts each of which has a first end attached to the roof frame front part.

13. The folding roof arrangement of claim 12 , wherein each of the roof frame side parts has a second end attached to a support structure of the vehicle.

14. The folding roof arrangement of claim 13 , wherein each of the roof frame side parts comprises at least two roof frame side part sections articulated to one another.

15. The folding roof arrangement of claim 1 , wherein the folding top covering is detachably fit to the folding top structure.

16. The folding roof arrangement of claim 1 , wherein each of the elastically deformable tensioning elements is an elastically bendable rod.

17. The folding roof arrangement of claim 16 , wherein the bendable rod has a substantially circular cross section.

18. The folding roof arrangement of claim 1 , wherein the elastically deformable tensioning elements are attached to the rear joints at the support structure for pivoting about pivot axes inclined to a Z axis that is substantially perpendicular to an X axis extending rearward from the roof frame front part and substantially perpendicular to a Y axis that extends between the roof frame side parts so that the tensioning elements perform a defined movement under a folding movement of the folding roof arrangement.
