Abstract

A collapsible chair (10), having a frame assembly (12) including a number of angled frame members (24). The upper ends of the angled frame members (24) are pivotally attached to upper connectors (64), and the lower ends are pivotally attached to feet (20). The frame assembly (12) as a whole is configured to expand outwardly from a central area (58). The frame assembly (12) further includes back support uprights (34) and rear corner upright members (32). Each of the upright members (32) has an upper end which is pivotally connected to one of said back support uprights (34) at a flexible joint (48). The chair (10) also includes a support surface (16), having a back portion (38) which is held in position by the back support uprights (34). The flexible joint (48) includes a resilient support assembly (30) which biases the back portion (38) to an upright position. This resilient support assembly (30) may include a number of different biasing mechanisms including an external spring (44), an internal spring (46), an internal strut (47), one or more resilient rods (70), a ball-and-socket joint (74), a hinge (76), a leaf-spring (80) or a resilient sleeve (72). The back support uprights may be joined together by a cross bar (54) or there may be two separate back support posts (52).
