Chairs For Special Purposes, Such As Reclining Chairs
(AREA)
Abstract
Improved tilting armchair, which is constituted from a fixed support frame, on which tilts the seat-backrest assembly, is essentially characterized by the aforementioned tilting of these two elements, which are immovably attached to each other, forming an invariable angle, it is carried out around a point located in the fixed frame at the appropriate height so that the operation can be carried out with a minimum effort, said point constituting the axis of rotation of a plate that relates it to the lower part of the seat frame, whose seat frame is related to the lower front area of the chair, which rises when it is tilted, acting as a footrest, thanks to the action of a lever articulated by its upper end to the frame of the seat, and by its lower end another arched lever, which before being fixed to the platform that joins it to the footrest, also serves as a point of articulation to a third was a lever that in turn serves as a point of articulation for its center, a secondary arm, while its free end is linked to one of the vertices of a plate that joins the frame of the seat with the possibility of rotation, being the aforementioned plate joined in turn articulated by a new lever to the fixed support frame of the set.
