Open lattice, foldable, self deployable structure

An open-lattice, foldable, self-deployable structure comprising:

• a plurality of spaced, bendable longitudinally extending members each having a curved cross section;
• a plurality of spaced, bendable and twistable diagonal members disposed to span between and intercept the longitudinal members forming cells, each cell bound by a portion of two spaced longitudinal members and two spaced diagonal members;
• the diagonal members joined to the longitudinal members at the cell boundary intersections of the diagonal members and the longitudinal members to form a load carrying structure;
• and
• the longitudinal members made of a material which bends and flattens by a predetermined amount below the material's yield point and the diagonal members made of a material which both bends and twists by a predetermined amount below the material's yield point so that the structure can be collapsed and then self-resurrected.
