Abstract
A sun shade is formed from two sheets of a tough, yet flexible material which have been cut to an appropriate shape and size, and sealed together at the edges to form a flat, balloon-like structure. A plurality of interconnecting flow channels or buoyant cells are stitched into the sheets to enable the structure to retain its shape without bulging. A conventional fill valve is provided for filling the space between the sheets with helium or another suitable gas. The shade is anchored above a selected surface using cables or other flexible connectors.
