FIG. 48 
(57) Abstract: A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied 
by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative 
to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin 
Actuators may control the relative movements of the backrest, front support, rear support, and central beams.
