Folding chair, characterized by being constituted by a frame that forms the backrest and front legs and that carries in its lower middle part a transverse cylindrical crosspiece, near whose respective ends are articulated small arms, also articulated by its opposite end to the back of the sides of a frame that forms the seat of the chair, said seat being articulated at its rear end to the rear legs by means of a cylindrical crossbar, the aforementioned rear legs being articulated at their upper end, which it extends above the plane of the seat, to the frame frame mentioned above, from which it follows that the seat of the chair, although it rests in position of use on the first crosspiece, that is to say the one arranged on said frame frame, does not is articulated directly on it, all in order that the different movable parts that make up the chair can be to describe a series of arcs that allow them to adopt a parallel position with respect to the frame frame and even, some of these parts, to be occluded with each other.
