Abstract
A sunshade assembly includes a flexible sunscreen, a rotatable winding shaft for winding and unwinding the sunscreen and two opposed guides for cooperation with two opposed longitudinal edges of the sunscreen. Each guide extends longitudinally in a curved manner in a plane which substantially is perpendicular to the sunscreen and in parallel to the respective longitudinal edge of the sunscreen. Longitudinal edge sections of the sunscreen are less stretchable than the remainder of the sunscreen and are tensioned in the longitudinal direction of the sunscreen.
Claims17
Sunshade assembly comprising:
- a flexible sunscreen having opposed longitudinal edges;
- a rotatable winding shaft configured for winding and unwinding the sunscreen;
- and
- two opposed guides, wherein each guide is configured to guide one of the longitudinal edges, wherein the guides maintain tension on the sunscreen in a direction transverse to a direction of travel of the sunscreen, wherein each guide extends longitudinally in a curved manner in a plane which substantially is perpendicular to the sunscreen and in parallel to the respective longitudinal edge of the sunscreen and wherein a central portion of each guide is elevated relative to the end portions thereof when considered in a longitudinal direction, and wherein the sunscreen when extended comprises an arcuate configuration wherein a middle portion is raised relative to the opposed longitudinal edges and wherein longitudinal edge sections of the sunscreen are less stretchable than the remainder of the sunscreen and wherein the longitudinal edge sections slidably engage a transversely angled and inclined guide surface on each of the guides to form the arcuate configuration of the sunscreen when extended.

An open roof construction assembly kit for a vehicle having an opening in a stationary roof, the kit comprising:
- a movable closure panel configured for opening and closing said roof opening;
- and
- a sunshade assembly comprising:
- a flexible sunscreen having opposed longitudinal edges wherein side sections of the sunscreen proximate the longitudinal edges are substantially non-stretchable and remainder of the sunscreen is stretchable;
- a rotatable winding shaft configured for winding and unwinding the sunscreen;
- two opposed guides, wherein each guide is configured to guide one of the longitudinal edges, wherein the guides maintain tension on the sunscreen in a direction transverse to a direction of travel of the sunscreen wherein each of the two opposed guides comprise a transversely inclined angled surface such that the longitudinal edges of the sunscreen slidably engage the inclined angled surfaces wherein the engagement of the longitudinal edges with the inclined angled surfaces provides tension on the flexible sunscreen traverse to the direction of travel when being extended, wherein each guide extends longitudinally in a curved manner in a plane which substantially is perpendicular to the sunscreen and in parallel to the respective longitudinal edge of the sunscreen, and wherein the sunscreen when extended comprises an arcuate configuration wherein a middle portion is raised relative to the opposed longitudinal edges;
- and
- a tensioning device coupled to the sunscreen, wherein the tensioning device is configured to cause tension of the longitudinal edge sections in the longitudinal direction by a winding force of the winding shaft.

An open roof construction assembly kit for a vehicle having an opening in a stationary roof, the kit comprising:
- a movable closure panel configured for opening and closing said roof opening;
- and
- a sunshade assembly comprising:
- a flexible sunscreen having opposed longitudinal edges;
- a rotatable winding shaft configured for winding and unwinding the sunscreen;
- two opposed guides, each guide having a longitudinal guide surface that comprises a back portion aligned with a plane that is substantially perpendicular to the sunscreen and in parallel to the respective opposed longitudinal edge of the sunscreen and having a top edge and a bottom edge, a top portion extending from the top edge of the back portion at a substantially right angle and an inclined angled surface extending from the bottom edge wherein the top portion, the back portion and the inclined angled surface form a channel:
- and
- wherein the angled surface of each guide provides support to one of the longitudinal edges, wherein the guides maintain tension on the sunscreen in a direction transverse to a direction of travel of the sunscreen, wherein each guide extends longitudinally in a curved manner in the plane, and wherein the sunscreen when extended comprises an arcuate configuration wherein the longitudinal edges are drawn into the guide through sliding engagement with the inclined angled surfaces such that a middle portion is raised relative to the opposed longitudinal edges.
