Abstract

A sunshade assembly for use in a vehicle roof assembly comprises a flexible sunscreen having at least a central part and two opposed inwardly folded longitudinal edges connected to the central part by means of folding lines. A winding shaft for winding and unwinding the flexible sunscreen is provided at the trailing edge and an operating beam at the leading edge of the sunscreen. Two opposed longitudinal guides retain therein and guide corresponding ones of the folded longitudinal edges of the sunscreen. The guides are provided with locking members for engaging an outer end of the inwardly folded longitudinal edges for preventing these edges from moving out of the longitudinal guides when the sunscreen is at least partly unwound. The sunscreen includes at least two members which are each arranged substantially parallel to a respective longitudinal edge and which are buckle-stiff in a direction parallel to said longitudinal edge.

First claim

What is claimed is:

1. A sunshade assembly, in particular for use in a vehicle roof assembly, comprising:
a flexible sunscreen having at least a central part, two opposed inwardly folded longitudinal edges connected to the central part by means of folding lines, a leading edge and a trailing edge,
a winding shaft configured to wind and unwind the flexible sunscreen at its trailing edge,
an operating beam attached to the leading edge, and
two opposed longitudinal guides configured to therein and guiding corresponding ones of the inwardly folded longitudinal edges of the flexible sunscreen, which guides are provided with locking members configured to engage an outer end of the inwardly folded longitudinal edges for preventing these edges from moving out of the longitudinal guides when the sunscreen is at least partly unwound,
wherein the flexible sunscreen is provided with at least two members which are each arranged substantially parallel to a respective longitudinal edge of said sunscreen and which are buckle-stiff in a direction parallel to said longitudinal edge, said buckle-stiff members extend at least partly within and preferably being guided by said longitudinal guides along the whole length from the operating beam to the winding shaft in the fully unwound condition of the sunscreen, and wherein the buckle-stiff members are strips provided in the central part of the sunscreen.

2. The sunshade assembly of claim 1 , wherein the strips are made of metal having a thickness of 0.05-0.15 mm.

3. The sunshade assembly of claim 1 , wherein the central part of the sunscreen is made of cloth-like material, the strip being positioned next to an edge of the cloth-like material and attached to the cloth-like material by a connecting member covering at least one side of the strip and an adjacent portion of the cloth-like material.

4. The sunshade assembly of claim 3 , wherein the connecting member covers both sides of the strip, the inwardly foldable longitudinal edge and the adjacent portion of the cloth-like material.

5. The sunshade assembly of claim 3 , wherein the connecting member is a self-adhesive tape or a woven or non-woven cloth attached to the strip and the material of the central part of the sunscreen.

6. The sunshade assembly of claim 1 , wherein each strip is attached on a side of the central part of the sunscreen.

7. The sunshade assembly of claim 1 , wherein each strip is guided by the respective guide.

8. The sunshade assembly of claim 7 , wherein each guide is shaped such that each area of the strip contacts the guide at least at two separated positions, one above and one below the strip.

9. The sunshade assembly of claim 8 , wherein each guide is shaped such that each area of the strip contacts the guide at three separated positions, two on one side of the strip and one on the other.

10. The sunshade assembly of claim 1 , wherein the buckle-stiff members are biased towards a spiral shape.

11. A sunshade assembly, in particular for use in a vehicle roof assembly, comprising:
a flexible sunscreen having at least a central part, two opposed inwardly folded longitudinal edges connected to the central part by means of folding lines, a leading edge and a trailing edge,
a winding shaft configured to wind and unwind the flexible sunscreen at its trailing edge,
an operating beam attached to the leading edge; and
two opposed longitudinal guides configured to therein and guiding corresponding ones of the inwardly folded longitudinal edges of the flexible sunscreen, which guides are provided with locking members configured to engage an outer end of the inwardly folded longitudinal edges for preventing these edges from moving out of the longitudinal guides when the sunscreen is at least partly unwound;
wherein the flexible sunscreen is provided with at least two buckle-stiff members which are each arranged substantially parallel to a respective longitudinal edge of said sunscreen and which are buckle-stiff in a direction parallel to said longitudinal edge, said buckle-stiff members extend at least partly within and preferably being guided by said longitudinal guides along the whole length from the operating beam to the winding shaft in the fully unwound condition of the sunscreen, and wherein the inwardly foldable longitudinal edges each comprise at least two integrated, substantially parallel buckle-stiff wires forming the buckle-stiff members.

12. The sunshade assembly of claim 11 , wherein said wires are provided at the inwardly foldable longitudinal edges.

13. A sunshade assembly, in particular for use in a vehicle roof assembly, comprising:
a flexible sunscreen having at least a central part, two opposed inwardly foldable longitudinal edges connected to the central part by means of folding lines, a leading edge and a trailing edge,
a winding shaft configured to wind and unwind the flexible sunscreen at its trailing edge,
an operating beam attached to the leading edge, and
two opposed longitudinal guides configured to retain therein and guide corresponding ones of the inwardly folded longitudinal edges of the flexible sunscreen, which guides are provided with locking members configured to engage an outer end of the inwardly folded longitudinal edges to inhibit these edges from moving out of the longitudinal guides when the sunscreen is at least partly unwound,
wherein the central part of the flexible sunscreen is provided with at least two strips which are each arranged substantially parallel to a respective longitudinal edge of said sunscreen and which are buckle-stiff in a direction parallel to said longitudinal edge, each strip extending at least partly within and being guided by said longitudinal guide along the whole length from the operating beam to the winding shaft in the fully unwound condition of the sunscreen.

14. The sunshade assembly of claim 13 , wherein the strips are made of metal having a thickness of 0.05-0.15 mm.

15. The sunshade assembly of claim 13 , wherein the central part of the sunscreen is made of cloth-like material, each strip being positioned next to an edge of the cloth-like material and attached to the cloth-like material by means of a connecting member attached to the strip and the material of the central part of the sunscreen.

16. The sunshade assembly of claim 15 , wherein the connecting member covers both sides of the strip, the inwardly foldable longitudinal edge and the adjacent portion of the cloth-like material.

17. The sunshade assembly of claim 13 , wherein each strip is attached on a side of the central part of the sunscreen.

18. The sunshade assembly of claim 13 , wherein each strip is guided by the respective guide, and wherein each guide is shaped such that each area of the strip contacts the guide at least at two separated positions, one above and one below the strip.

19. The sunshade assembly of claim 13 , wherein each strip is guided by the respective guide, and wherein each guide is shaped such that each area of the strip configured to contact the guide at three separated positions, two on one side of the strip and one on the other.

20. An open roof construction for a stationary roof part of a vehicle comprising:
a movable closure member configured to mount to the stationary roof part and open and close an opening in the stationary roof part, and
a sunshade assembly configured to be mounted below the movable closure member, the sunshade assembly comprising:
a flexible sunscreen having at least a central part, two opposed inwardly folded longitudinal edges con
