ARMCHAIR AND SUPPORT STRUCTURE Russian patent published in 2014 - IPC A47C1/23 A47C1/24 

FIELD: personal use articles.

SUBSTANCE: invention relates to an armchair. The armchair has a seat support structure, a seat, and a support frame. The support frame is formed by a base on castors, the height regulation mechanism and the main transverse bar. The seat is designed so that to enable its selective movement relative to the support frame and has a fixed position and a free position. The back has a back frame and a deformable cover. The back is designed so that to enable its divergence between the vertical position and the maximum divergence position. The divergence mechanism contains deformable elements linking the seat to the support frame and ensuring their interaction. The divergence resistance mechanism is designed so that to enable its selective actuation; in the actuated state the mechanism resists the back movement towards the maximum divergence position.

EFFECT: comfort of the user position in the armchair.
