Lo schienale (3) della sedia fa parte di una quarta struttura indipendente dalle suddette tre strutture e montata articolata su di esse intorno al suddetto asse comune (A). Nella condizione d'impiego della sedia, lo schienale (3) può essere fatto oscillare all'indietro contro l'azione di mezzi elastici.(Figura 1)
