Abstract:
1. A seat structure comprising a support frame, an elastic fabric sheet secured to said frame along opposed lateral sides of said frame and extending across a top seating portion of said frame, tensioning means to stretch said elastic fabric sheet and position same at a permanent elevated position above said seating portion sufficient to support an intended load thereon in suspension over said seating portion, said tensioning means being constituted by at least one extensor member having a length of substantially the same length as said opposed lateral sides and a cross-sectional shape for the placement of said extensor member at a predetermined location in a space between said seating portion and said elastic fabric sheet, said cross-sectional shape having a height whereby when said extensor member is slid laterally over said frame to a permanent tensioning position along one of said opposed lateral sides of said frame, said elastic fabric sheet undergoes an upward displacement in at least a part thereof and stretching to tension same to cause said elastic fabric sheet to apply a biasing force against said extensor member, and retention means to maintain said extensor member at said tensioning position.
