Abstract
Silla del tipo inclinable que incluye una base, un asiento y espaldar, en que la base soporta pivotalmente al asiento con dos uniones paralelas de unaunion de cuatro-barras, en que una de las uniones se extiende para soportar al espaldar. La union de cuatro-barras está duplicada en cada lado de la silla,formando dos uniones paralelas opuestas, o ciguenales, desde los extremos vueltos hacia arriba de los tubos que pasan a través de la base, en forma paralelapero verticalmente descentrados; la bas e forma así la barra fija de la union con su barra opuesta o acoplador, formado por el asiento. Un resorte dentro de labase es operativo en uno (o ambos) tubos para forzar a la silla a una posicion vertical hacia arriba. Los tubos están pivotalmente conectados con el asiento yuno de los tubos se extiende y está fijamente conectado con el espaldar. A medida que se inclina el espaldar, el mecanismo de cuatro-barras se engancha ylevanta al asiento, que usa así el peso del ocupante para contrarresta r la reclinacion. También se describe un apoya-brazos ajustable que puede ser fácilmentelevantado, o bajado y, opcionalmente, hecho rotar en un plano horizontal. Un aspecto adicional de la presente descripcion es un apoya-cabezas que se coloca ensu l ugar cuando la silla se reclina y se retrae cuando la silla retorna a su posicion vertical hacia arriba.Chair of the tilting type that includes a base, a seat and backrest, in which the base pivotally supports the seat with two parallel joints of a four-bar joint, in which one of the joints extends to support the backrest. The four-bar joint is duplicated on each side of the chair, forming two opposite parallel joints, or crankshafts, from the upturned ends of the tubes that pass through the base, in parallel but vertically offset form; the base thus forms the fixed bar of the union with its opposite bar or coupler, formed by the seat. A spring inside the base is operative in one (or both) tubes to force the chair to an upward vertical position. The tubes are pivotally connected to the seat and one of the tubes extends and is fixedly connected to the back. As the back is tilted, the four-bar mechanism engages and lifts the seat, which thus uses the occupant's weight to counteract the recline. Also described is an adjustable armrest that can be easily raised, or lowered and, optionally, rotated in a horizontal plane. An additional aspect of the present description is a headrest that is placed in place when the chair reclines and retracts when the chair returns to its upright vertical position.
