Abstract
An inflatable, self-supporting cover suitable for placement over a body and comprising a top sheet, a bottom sheet and ribs extending between such sheets to form a plurality of compartments extending transverse to the length of the cover. The ribs are formed in the shape of a flattened oval and then fastened between such sheets. A duct extending longitudinally of the length of the cover connects with the compartments and with a source of pressurized air which inflates the compartments, causing them to assume an arch-like shape extending transverse to the length of the cover and spanning said body. An alternative embodiment includes a second cover section fastened to the cover bottom sheet and having a plurality of compartments, each with at least one port therein. The second cover section compartments connect with the duct whereby pressurized air passes to the second cover section compartments and from each port therein to circulate air about the body beneath the cover.
