ABSTRACT:
A chair has a frame, a main link having an inner end pivoted on the frame about an inner axis fixed relative to the frame and an outer end defining an outer axis parallel to the inner axis. An outer arm has an inner end pivoted at the outer axis on the outer axis of the main link and an outer end carrying a footrest. An inner wheel is fixed nonrotatably on the frame at the inner axis, and an outer wheel is fixed nonrotatably on the inner end of the outer arm at the outer axis. A chain, belt, or the like connected to both of the wheels couples same together for joint synchronous rotation. A drive can pivot the main link about the inner axis and thereby pivot the outer arm about the outer axis.
