Inflatable support members and structures including the same

摘要

An embodiment of the invention is an inflatable support member having at least one tension point to establish a bend in the inflatable support member. The inflatable support member includes a first sheet and a second sheet sealed around their respective edges. A tension point is formed by enlarging the seam area where a bend in the inflatable support member is desired. Alternate embodiments of the invention include structures including the inflatable support member. An alternate inflatable support member includes a first sheet and second sheet, the second sheet having an elasticity less than that of the first sheet by using different materials, additional materials or stretching the second sheet.
