Abstract
A chair with a tilting backrest including two flexible supporting sectional elements set at a distance from one another in a transverse direction, wherein each of said supporting sectional elements is provided with a plurality of through notches that form respective points of localized bending that enable bending backwards of the supporting sectional element, and wherein each of said notches has a first contact surface and a second contact surface that, in the position of maximum inclination backwards of the backrest, come to bear upon one another to stop bending backwards of the sectional element, wherein the projections of said first and second contact surfaces in a vertical plane parallel to the longitudinal axis of the chair are at least partially superimposed on one another in such a way as to prevent visual communication through said notches in a direction orthogonal to said vertical plane.
