Abstract: A folding chair comprising first and second metal frames defining seat and backrest parts, which frames are hinged together and to supporting legs; seat and backrest fabric portions stretched over said first and second frames, and an elastic or elastomeric fabric strip connected to said fabric portions and folded around a transversal rear element of first frame to keep the chair fabric taut.

Abstract: A folding chair having a first, seat frame and a second, backrest frame, the frames articulated to supporting leg frames and lateral armrests. A cup member is secured to the rear ends of the seat frame, and the backrest frame is hinged to the cup member. A toggle element is pivoted to the cup member and to a rear leg of the chair, the toggle element being provided with a rest portion which comes to rest against the rear leg. A retainer in the form of a detent and a recess are provided on the cup member and on the toggle element, respectively, to prevent the rotation of the toggle element with respect to the cup member when the chair is open.

Abstract: The invention concerns a dismountable folding chair or armchair structure, and in particular, a "director"-type chair, in which a fold-up seat, defined by pivoted elements, crossing one another, is hinged to side frames defining the supporting legs, the armrests and backrest elements of the chair.The folding seat and the side frames include reciprocal connecting means which may snap on and off, to stiffen and hold the chair folded down. The seat and backrest fabrics, moreover, are removably fitted in order to allow the fabrics themselves to be changed.
