US Patent 7588295 Legged support

A seating assembly can include a tension ring, two or more legs and a frame. The legs are attached to the tension ring using fasteners, welds and/or the like. The frame is configured to contact each leg at one or more locations, at which forces exerted on the frame can be transferred to the legs. Movement of the legs relative to the tension ring can cause tensile forces to be exerted on the tension ring. When legs are spaced equally apart from one another around the tension ring, the tensile forces on the tension ring balance each other.
