Abstract
A sun barrier, sign, screen or reflector or combination thereof. The barrier may be used, for instance, for reducing the sun exposure to the interior of an automobile. The barrier includes a flexible, cloth-like panel and a barrier control element with the control element selectively positioning the panel to a generally planar condition or a coiled storage condition. The control element may be a coiled strip spring or constant force spring attached to one edge of the barrier panel.

A barrier comprising a compliant panel of material capable of being deformed and collapsed into a generally compact form and then stretched out from such compact form into a generally planar form to serve as a sun barrier, sign, screen or reflector or combination thereof, said panel having lower, upper, and side edges, and a collapsible control means attached to and extending along one edge of said panel to control said one edge, said control means having a collapsed condition which collapses said one edge and an extended condition which extends said one edge and wherein said control means is a coiled, strip spring which, when collapsed, forms a cylinder, and, when extended, forms a rectilinear strip and wherein
- said one edge of said panel is provided with an elongated pocket extending therealong and in which said spring is disposed in said pocket to extend therealong when said spring is extended to hold said pocket and said one edge straight, said spring being captured in said pocket such that said one edge will follow the form of said spring.
