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 edges 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 edges of the flexible sunscreen, which 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. The central part of the flexible sunscreen mainly is manufactured from a first material with a first stiffness wherein of the inwardly folded longitudinal edges and of the parts of the central part adjacent the edges 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 folded longitudinal edges, each inwardly folded longitudinal edge being connected to the central part proximate a folding line, and two opposed longitudinal guides configured to receive 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 prevent said inwardly folded longitudinal edges from moving out of the longitudinal guides, wherein a first portion of the central part of the flexible sunscreen between the two opposed inwardly folded edges is manufactured from a first material with a first stiffness and wherein at least part of the inwardly folded longitudinal edges and at least a part of a second portion of the central part adjacent the edges are made of a second material with a second higher stiffness, wherein each folding line is formed in the second material, and wherein the flexible sunscreen at the location of the folding line has a reduced thickness.

2 . The sunshade assembly of claim 1 wherein a thickness of the flexible sunscreen immediately adjacent and on opposite sides of the folding line is larger than at the folding line.

3 . The sunshade assembly of claim 2 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.

4 . The sunshade assembly of claim 1 wherein the thickness of the second portion of the central part is larger than at the folding line and wherein the thickness of the inwardly folded longitudinal edges substantially equals the thickness at the folding line.

5 . The sunshade assembly of claim 1 wherein a surface of the flexible sunscreen at the folding line includes a concave recess facing the outer end of a respective inwardly folded longitudinal edge.

6 . The sunshade assembly of claim 5 wherein a second surface of the flexible sunscreen at the folding line facing in a direction opposite to the surface includes a second concave recess.

7 . The sunshade assembly of claim 5 wherein at the folding line only the surface includes a concave recess.

8 . The sunshade assembly of claim 1 wherein the inwardly folded longitudinal edges are partly made of the second material with the second higher stiffness.

9 . The sunshade assembly of claim 1 wherein the inwardly folded longitudinal edges and the second portion of the central part adjacent each respective the inwardly folded longitudinal edge are partly made of the second material with the second higher stiffness.

10 . The sunshade assembly of claim 1 wherein the second portion of the central part adjacent each respective the inwardly folded longitudinal edge is partly made of the second material with the second higher stiffness.

11 . The sunshade assembly according to claim 8 wherein the second material is impregnated in surfaces of the inwardly folded longitudinal edges.

12 . The sunshade assembly according to claim 9 wherein the second material is impregnated in surfaces of the inwardly folded longitudinal edges and in surfaces of the second portion of the central part.

13 . The sunshade assembly according to claim 10 wherein the second material is impregnated in surfaces of 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 inwardly folded longitudinal edges.

15 . 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 folded longitudinal edges and to the second portion of the central part.

16 . 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.

17 . 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.

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