<p>A structural framework for a convertible armchair or sofa comprising a box-shaped base supporting a plurality of frames hinged to one another, including a particular frame suitable, alone, for directly or indirectly supporting a seat cushion on one of its sides and, in combination with the other frames, for supporting a mattress on its other side, and mechanisms for the displacement of said frames and of a backrest and supporting foot, in relation to one another and with respect to the base, between: a stable configuration as a sofa or armchair, wherein the frames remain inside said base, where they identify a cavity for containing the folded mattress; and a stable configuration as a bed wherein the frames extend forwards, becoming aligned to define a horizontal resting surface that extends beyond the base and is supported by the foot, while the backrest moves underneath the resting surface, and a stable configuration as a recliner, wherein, by comparison with the configuration as an armchair or sofa, the backrest is tilted further backwards and the particular frame extends further forwards and/or is tilted upwards.</p> |
