Abstract
E' fornito un meccanismo di supporto a interbloccaggio per supportare l'elemento sessile e lo schienale di una poltrona, particolarmente una poltrona da ufficio. Nel meccanismo di supporto è utilizzato un sistema a leveraggio per interbloccare l'elemento sessile con lo schienale, in modo tale che la poltrona è in grado di muoversi dolcemente quando una persona seduta si muove. La Porzione anteriore di un elemento a leva è collegata girevolmente alla porzione anteriore di un elemento a telaio che è supportato da un elemento di fissaggio e che si estende verso la porzione anteriore dell'elemento sessile. L'elemento a leva è fissato con l'ausilio di alberini orizzontali sui lati destro e sinistro dell'elemento sessile, alle porzioni inferiori di barre di supporto dello schienale. Un elemento repulsivo è previsto tra l'elemento di telaio e l'elemento a leva è fatto oscillare sugli alberi orizzontali. Un elemento per ricevere l'elemento sessile include un elemento di ricezione di elemento sessile posteriore. L'elemento di ricezione dell'elemento sessile anteriore è previsto con l'ausilio di un elemento elastico in modo tale che esso può spostarsi verso l'alto e verso il basso e verso destra e sinistra, sulla porzione anteriore dell'elemento di telaio. L'elemento di ricezione di elemento sessile posteriore è previsto, con l'ausilio di alberi paralleli agli alberi orizzontali, sulla porzione posteriore dell'elemento a leva per cui esso può oscillare su questi alberi. L'elemento sessile è supportato dagli elementi riceventi l'elemento sessile anteriore e posteriore.
