Embodiment Construction

[0037] Referring to the accompanying drawings in detail below, from figure 1 Initially, reference numeral 10 generally designates a reclining or synchronous chair arrangement constructed in accordance with the present invention. Apparatus 10 generally includes a support frame 12 and a movable frame 14 . The support frame 12 is connected to a post 16 extending downwardly towards the support surface. A plate 18 designed to support the back of the chair is fixedly connected to the above-mentioned movable frame 14 . refer to figure 2 , the support structure 10 is synchronized and also includes a shelf 20 providing a mounting location for the seat.

[0038] like figure 2 and 6 As clearly shown, the movable frame 14 is fixed to the support frame 12 by pins 22 , so that the movable frame 14 can be tilted relative to the support frame 12 . The spring 24 serves as an elastic return element of the movable frame 14 . Additionally, if figure 1 and 10 As clearly shown, the suppo...

Abstract

A support for tilting or synchronized chair is provided. The device (10) includes a supporting frame (12), a mobile frame (14), an elastic member (24), a stiffness adjustment mechanism coupled with the elastic member, a locking mechanism for engaging the mobile frame with the supporting frame, and an actuation device for engaging and disengaging the locking mechanism. The actuation device includes a rocker arm (36) and a return arm (40). The return arm is connected to the end of the rocker arm that the locking mechanism is attached. The rocker arm has at least two positions of stable equilibrium that are determined by the engagement or disengagement of the locking mechanism. An alternative embodiment includes an outer shell having first and second pins that are coupled with the backrest frames. The second pin may be positioned within a slot formed in the shell so that the backrest frame may move between upright and reclined positions.

Description

technical field [0001] The invention relates to a support structure for a reclining or synchronous chair. Background technique [0002] Support structures for reclining chairs are well known in the prior art. Generally, the supporting structure of the chair comprises: at least one support frame connected to the chair column; a movable frame hinged to the above support frame so as to be able to tilt relative to the above support frame; a rigid adjustment mechanism for elastically restoring the movable frame; and, A locking system above which the movable frame is actuated by a knob. The locking system may allow the movable frame to be selectively positioned in a plurality of predetermined tilted positions. The support structure of reclining or synchronous chairs is also usually provided with a seat raising and lowering system, typically comprising a lever controlled pneumatic piston. [0003] In known forms of chair support structures, the aforementioned stiffness adjustmen...
