Abstract

ENCIMA DEL TUBO DE APOYO (13) DE LA CRUZ DE PIE (11) SE MONTA UN SOPORTE (21). ESTE TIENE UN ANGULO DE INCLINACION QUE PERMITE BAJAR EL ASIENTO (17) DE LA POSICION REPRESENTADA EN LA FIGURA. UN MECANISMO DE RESORTE DE TORSION (23) TIENDE A BASCULAR EL ASIENTO POR EL EJE DE GIRO (37) HACIA ARRIBA. COMO DISPOSITIVO DE BLOQUEO SIRVE UNA SUSPENSION ELASTICA POR GAS (27) QUE PUEDE DESACTIVARSE MEDIANTE LA TECLA (28). ESA SUSPENSION ELASTICA POR GAS (27) ACTUA ESENCIALMENTE EN EL MISMO SENTIDO QUE EL SOPORTE (21), PERO TIENE UN ANGULO DE INCLINACION MAYOR AL DEL SOPORTE, POR LO CUAL EL ESPACIO CENTRAL DEBAJO DEL ASIENTO (17) QUEDA LIBRE DE ELEMENTOS MECANICOS. DE ESTA MANERA, LA SILLA SATISFACE LAS MAS ALTAS EXIGENCIAS ESTETICAS. MEDIANTE UN TORNILLO DE AJUSTE (51) CON UN BOTON DE AJUSTE (63) AXIALMENTE DESPLAZABLE, EL USUARIO PUEDE ADAPTAR LA TENSION DEL MECANISMO DE RESORTE DE TORSION (23) A SU PESO.
