ABSTRACT:
An articulated support rod fit for realizing the frame of a forward folding back of a seat, such as sofa, armchairs or the like. The rod is formed by a row of arms connected in an end-to-end relation by means of a frictional articulation, and comprises means for the connection to the main frame of the seat and, at the free end, a flat elongated plate, which may be either thick or thin according to the material used. Each arm comprises stop means at its end sides engaging with corresponding stop means provided on the corresponding end side of adjacent arms, to limit the mutual rotation of the arms to a first position wherein they are substantially aligned and to a second position where each arm is inclined with respect to the adjacent one of an angle lower than 90.degree..
