Abstract

A flexible sunscreen is provided intended for use in a sunshade assembly of the type comprising a flexible sunscreen having a central part and two opposed inwardly folded longitudinal edge flaps connected to the central part by means of folding lines, and two opposed longitudinal guides for receiving therein and guiding corresponding ones of the inwardly folded longitudinal edge flaps of the flexible sunscreen, which guides are provided with locking members for engaging an outer end of the inwardly folded longitudinal edge flaps for preventing these edge flaps from moving out of the longitudinal guides. The central part of the flexible sunscreen mainly is manufactured from a first material with a first stiffness wherein of the inwardly folded longitudinal edge flaps and of the parts of the central part adjacent the edge flaps at least part is made of a second material with a second higher stiffness.

First claim

What is claimed is:

1. A sunshade assembly comprising:
a flexible sunscreen having a central part and two opposed inwardly foldable longitudinal edge flaps, each inwardly foldable longitudinal edge flap being connected to the central part proximate a folding line, and being foldable between an unfolded position in which each inwardly foldable longitudinal edge flap, starting from the folding line, extends away from the central part to an outer end and is coplanar with the central part, and an inwardly folded position in which each inwardly foldable longitudinal edge flap, starting from the folding line, substantially extends back toward the central part and forms an acute angle with the central part, and
two opposed longitudinal guides configured to receive therein and guide corresponding ones of the inwardly foldable longitudinal edge flaps of the flexible sunscreen when in the inwardly folded position, which guides are provided with locking members configured to engage the outer end of the inwardly foldable longitudinal edge flaps to prevent said inwardly foldable longitudinal edge flaps from moving out of the longitudinal guides,
wherein a first portion of the central part of the flexible sunscreen between the two opposed inwardly foldable longitudinal edge flaps is manufactured from a first material with a first stiffness and wherein at least part of the inwardly foldable longitudinal edge flaps and at least a part of a second portion of the central part adjacent the inwardly foldable longitudinal edge flaps are made of a second material with a second higher stiffness than the first stiffness, the second material being secured to the first material in the second portion of the central part, wherein each folding line is formed in a connecting portion that connects a longitudinal extending edge of the second portion of the central part to an opposed longitudinal extending edge of each inwardly foldable longitudinal edge flap, and
wherein each connecting portion at the folding line comprises the first material directly secured to the second material and having a reduced thickness relative to the longitudinal extending edge of the second portion of the central part and the opposed longitudinal extending edge of each inwardly foldable longitudinal edge flap.

2. The sunshade assembly of claim 1 wherein the thickness of the flexible sunscreen immediately adjacent and at one side of the folding line is equal to the thickness of the flexible sunscreen immediately adjacent and at an opposite side of the folding line.

3. The sunshade assembly of claim 1 wherein the flexible sunscreen has a first surface facing the inwardly foldable longitudinal edge flaps when the inwardly foldable longitudinal edge flaps are in the inwardly folded position, and an opposite second surface, and wherein at the folding line, at least the first surface includes a recess.

4. The sunshade assembly of claim 3 wherein the second surface of the flexible sunscreen at the folding line includes a second recess.

5. The sunshade assembly of claim 3 wherein at the folding line, only the first surface includes the recess.

6. The sunshade assembly of claim 5 wherein the recess forms a hinge.

7. The sunshade assembly of claim 4 wherein the recess and the second recess are each concave.

8. The sunshade assembly of claim 3 wherein the recess is concave.

9. The sunshade assembly according to claim 1 wherein the second material is impregnated in surfaces of the inwardly foldable longitudinal edge flaps.

10. The sunshade assembly according to claim 1 wherein the second material is impregnated in surfaces of the inwardly foldable longitudinal edge flaps and in surfaces of the second portion of the central part.

11. The sunshade assembly according to claim 1 wherein the second material is impregnated in surfaces of the second portion of the central part.

12. The sunshade assembly according to claim 1 wherein the second material comprises a separate layer of said second material at least partly surrounding and at least partly attached to the inwardly foldable longitudinal edge flaps.

13. The sunshade assembly according to claim 1 wherein the second material comprises a separate layer of said second material at least partly surrounding and at least partly attached to the inwardly foldable longitudinal edge flaps and to the second portion of the central part.

14. The sunshade assembly according to claim 1 wherein the second material comprises a separate layer of said second material at least partly surrounding and at least partly attached to the second portion of the central part.

15. The sunshade assembly according to claim 1 , wherein a coefficient of friction of the second material is lower than a coefficient of friction of the first material.

16. The sunshade assembly according to claim 1 , wherein the second material is a plastic material.

17. The sunshade assembly of claim 1 , wherein the second material is impregnated in surfaces at the folding line.
