Abstract

Articulated chair characterized by comprising a tube frame preferably made of light alloy whose parts are related by elements capable of allowing the relative movement of the component parts with each other so that the folding is performed by elevating the front part, leaving the assembly collected at the minimum space and the fixing system consisting of having two transverse rods located on the back of the seat the upper one of which joins the two rear legs together and at the ends of which two hooks are loosely arranged which are coupled on the lower rod that joins only the ends of the seat spars so that in normal position of use they oppose the folding since this tends to separate the two rods mentioned to which the hooks are opposed mainly when the chair has weight on it sufficing to lighten it from the same and tilt it backwards so that the hooks are released by gravity and the folding is done at that moment, the inverse operation being enough for the hooks to be fixed and the normal use of the chair since it extends with the inclination and when it is lowered to its normal position, the hooks fall by gravity, remaining fastened in that position. Position and more asserted when loading the chair with step. (Machine-translation by Google Translate, not legally binding)
