Embodiment Construction

[0043] As can be seen from Fig. 1, the chair of the present invention is generally designated by reference numeral 1, and it includes a frame generally designated by reference numeral 2, and frame 2 includes a pair of front legs 3a and a pair of rear legs 3b, front legs 3a and The rear legs 3b are resting on the floor and are connected at their ends to a central member generally indicated by the reference numeral 4 and forming a substantially horizontal longitudinal axis X supporting the seat 5 .

[0044] As a continuation of said front leg 3a are the same number of first mullions 3c, which are also connected to the end of the central shaft 4, preferably they are connected to the end of the central shaft as one piece with this front leg 3a, thus Forms a rectilinear structure with the front leg 3a, but not necessarily so.

[0045] The top 6a of the backrest 6 is connected to the first mullion 3c by a pair of first flexible couplings, each of which is generally indicated by the ...

Abstract

A chair with variable pitch having a frame set to rest on the floor, at least one central element that creates a substantially horizontal longitudinal axis supported by the frame, a seat supported by the central element, one pair of first stiles parallel to each other and set at the ends of the central element, and a backrest that has its top connected to the first stiles through first flexible couplings and its bottom connected to the seat through a second flexible coupling. The seat is connected to the central element through swivel means that allow the planar rotary-transverse movement of the seat, combined with a rotary rocking movement of the backrest around a longitudinal axis created by the flexible couplings.

Description

technical field [0001] The present invention relates to a chair capable of adopting different inclinations or postures under the action of the propulsion exerted by the occupant on the seat and backrest. Background technique [0002] There are several variable-recline chairs available on the market that achieve variable recline by exploiting the flexural deformation capabilities of the structure that makes up the seat or backrest, or in some cases by installing flexible members between structural components of the chair itself. slope. [0003] A person sitting in a chair changes the sitting posture as desired by changing the inclination of the chair by applying pressure to the seat or the backrest or both. [0004] It is well known that if frequently changed from a forward to a reclined position, the user will rub against the surface of the seat and inevitably experience inconvenience and discomfort. [0005] Furthermore, the most natural sitting posture a user is prone to...
