ABSTRACT:
A folding chair having a novel hinge and joint surface configuration that forms a substantially rigid structure approximating conventional non-folding chair designs. In one embodiment, the present invention provides a folding chair comprising a seat frame, a backrest frame hinged proximally to the rear edge of the seat frame and forwardly collapsible over the upper surface of the seat frame, and back legs hinged to the rear edge of the seat frame and forwardly collapsible over the lower surface of the seat frame. The chair, in one embodiment, further comprises front legs hinged to the seat frame and collapsible over the back legs. In an assembled state, the back legs and the backrest frame each abut against elements of the chair at joint surfaces, which limit the range of motion of the hinged members to thereby create a chair having a rigid support structure. In one embodiment, the seat frame, backrest frame, and back legs unfold into an interlocked configuration enhancing the stability of the chair.
