摘要： A folding chair, which is foldably collapsible in a scissors-like folding operation, forms a long narrow bundle when collapsed, which fits into a tubular bag. The folding chair includes a pivotally jointed backrest support member which can be placed in various configurations to allow reclining movement thereof. The folding chair includes a frame assembly and a flexible hammock-type of fabric seat member which is mounted on, and supported by, the frame assembly. In a preferred embodiment, the frame assembly includes a plurality of interconnected X-members. The X-members cooperate to define a cage member when the chair is in an open configuration thereof. The frame assembly further includes a position fixing mechanism for temporarily and disengagably fixing the position of the seat back, to allow the frame assembly to be temporarily locked in a particular orientation thereof. In a particularly preferred embodiment, the position fixing mechanism includes a vertically oriented rack gear attached to a vertically oriented pillar and having teeth formed therein, and a spring-loaded pawl, pivotally attached to a slidably adjustable brace, for locking placement between the teeth of the vertical rack. A foldably collapsible and removable foot rest for a folding chair is also disclosed. The foot rest may be used with folding chairs of various structural configurations, and includes at least one connector for attaching to a seat portion, and a lower reinforcement for engaging a support member on a folding chair.
