ABSTRACT:
A folding chair defined by a U-shaped rest, a seat, a pair of vertically extending front legs and a pair of obliquely downwardly extending rear legs, wherein the rest, the front legs and the rear legs are connected together for pivotal movement about a first transverse axis. Each rear leg is provided with a slider to which first, second and third struts are connected for pivotal movement about a second transverse axis, with the first strut being connected to the rest, the second strut being connected to the seat and the third strut being connected to a front leg for pivotal movement about third, fourth and fifth transverse axes, respectively. The seat is connected to the front legs for pivotal movement about a sixth transverse axis and is supported on the pair of sliders. All first and third struts are disposed in the same plane, intersecting a surface defined by the pair of rear legs. The chair is folded by raising the seat upwardly, thereby moving the sliders upwardly along the rear legs so that the rest and the rear legs are caused to pivot toward the front legs, with the first, second and third pairs of struts being caused to engage the rest, the seat and the front legs, respectively.
