Abstract
Abstract Folding chair adjustable for different sitting-rocking and reclining positions comprising two generally rectangular frames coupled by links for relative scissor-like rocking movement and folding, a flexible web seat, with means for easily removing and changing the length thereof and an adjustable frame-positioning strap interconnecting the frame legs, the frames and links being spaced by laterally offset members to prevent pinching of the user''s hands during relative movement of the frames and links.

Total Claims: 6
Claim 1
Independent Claim
193 words
A folding, rocking and reclining chair comprising: a. a pair of complimentary generally rectangular frames, one of which is positioned within the other for relative scissor-like angular movement, the frames being connected by a sheet of flexible material to form a seat, and having means restraining the lower ends of the frames, b. a link pivotally interconnecting adjacent frames sides respectively, at each side of the chair for guiding the frames in said angular movement, and c. said link at its end connecting with the outside frame including offset boss-like structure for laterally spacing said link and frame, the link at its opposite end having lateral spacing bosses to form therewith a ''''T,'''' and an arm rest including a support interconnecting the frames, the T bosses interconnecting respectively the arm rest support and inner frame such that risk of pinching therebetween of the chair occupant''s hands is minimized incident to said angular movement and the arm rest at its opposite ends having pivotal connection respectively, with the support and the outer frame, and having depending side flanges at opposite sides thereof extending longitudinally along the arm rest for laterally shielding said pivotal connections.
