Abstract

Folding-folding armchair that is essentially characterized by the fact of presenting the base of the seat and the backrest panel conveniently articulated with each other forming a dihedral of variable aperture between two stable limits of inclination, for which the two pairs of front legs and The rear seats of the chair are suitably extended so that the upper ends of each pair are concurrent at a joint point of articulation with respective billets of relatively short appropriate length articulated with each other, the billets of which on their part articulate with two respective side points close to each other. the front edges of the handrails that constitute the support arms of the chair, are able to describe a bidirectional rotation of 180º limited in the two extreme positions of each billet by the own arms that for it are endowed with a fin that acts as a stop , also connecting the frame of legs and arms thus formed with the dihedral seat-backrest by two pairs of fixed articulation points and a third displaceable pair, all in such a way that the first pair is located at half height of the front legs connecting with the flanks of the front part of the body. seat, while the second pair of articulations is established between the rear ends of the armrests of the chair and two horizontally aligned points of the backrest, while the displaceable link in question is verified between the rear legs and some perforations slides established in the two flanks of the seat, near the articulations of this with the backrest, this special system of saddle on the one hand enabling the total folding of the chair on the same plane by overlapping legs and arms, and, on the other, once deployed, the adoption of the two positions of maximum and minimum inclination -the backrest achievable by simple jumps and longitudinal displacements s imultºneos of the referred back and forward arms respectively, which is achieved thanks to the special arrangement and rotation of the aforementioned billets.
