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 inwardly folded edges is manufactured from a first material with a first stiffness and wherein 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,
wherein the inwardly folded longitudinal edges are completely made of an assembly of a member made of said second material and a separate reinforcement enclosed in said member,
wherein the second portion of the central part comprises two opposite legs of the second material enclosing and attached to the first material of the central part of the sunscreen, and
wherein in an inwardly folded position within its guide, each inwardly folded longitudinal edge is positioned entirely inwardly of its folding line.

2. The sunshade assembly according to claim 1 , wherein the inwardly folded longitudinal edges and the second portion of the central part adjacent the edges are partly made of the second material with the second higher stiffness.

3. 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.

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

5. The sunshade assembly according to claim 1 , wherein the second material is impregnated in surfaces of parts of the second portion of the central part adjacent the edges and wherein the flexible sunscreen at the folding line has a reduced thickness.

6. 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 edges.

7. The sunshade assembly according to claim 6 , wherein the inwardly folded longitudinal edges each, in the inwardly folded position, define an inner surface and an outer surface and wherein said separate layer at the inner surface extends substantially up to the folding line and wherein said separate layer at the outer surface ends at a distance from said folding line, wherein said distance ranges from 5-50% of a width of the inwardly folded longitudinal edges measured between a folding line and respective outer end.

8. The sunshade assembly according to claim 6 , wherein the inwardly folded longitudinal edges each, in the inwardly folded position, define an inner surface and an outer surface and wherein said separate layer at the inner surface extends substantially up to the folding line and wherein said separate layer at the outer surface ends at a distance beyond said folding line and extends over at least part of the central part of the flexible sunscreen.

9. The sunshade assembly according to claim 8 , wherein the part of the separate layer extending beyond the folding line is not attached to said central part of the flexible sunscreen.

10. The sunshade assembly according to claim 1 , wherein said second material of the inwardly folded longitudinal edges partly encloses or extends through the central part of the sunscreen and, at the folding line, has a reduced thickness.

11. The sunshade assembly according to claim 1 , wherein a combination of the two opposite legs enclosing and attached to the second portion of the central part of the sunscreen and the second portion of the central part has a same thickness as the first portion of the central part.

12. 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 inwardly folded edges is manufactured from a first material with a first stiffness and wherein the inwardly folded longitudinal edges and at least a part of a second portion of the central part adjacent the edges at least part is made of a second material with a second higher stiffness,
wherein each folding line is formed in the second material, wherein the inwardly folded longitudinal edges are completely made of an assembly of a member made of said second material and a reinforcement enclosed in said member,
wherein the second portion of the central part comprises a portion of the first material having opposed legs made of the second material on opposite sides of the first material,
wherein said second portion of the central part has a reduced thickness for reducing or eliminating a step at an interface between the second portion of the central part and said legs, and
wherein in an inwardly folded position within its guide, each inwardly folded longitudinal edge is positioned entirely inwardly of its folding line.
