ARMCHAIR WITH ROCKING BACK Russian patent published in 2011 - IPC A47C1/32 

FIELD: personal use articles.

SUBSTANCE: invention relates to an armchair with a rocking back. The armchair comprises a support structure, a seat, a back with a support and an elastic facility. The seat is connected with a support structure by means of a joint in the form of a hingedly joined parallelogram that includes the first arm and the second arm, to ensure movement of the seat between the lowered position and the raised position. The back is installed so that it could slide between the vertical position and the position inclined backwards. Movement of the back into the backward inclined position causes seat displacement into the raised position and vice versa. The elastic facility tries to return the seat into the lowered position, and the back - into the vertical position. The seat is carried by a sliding support installed so that the inclination of the seat support backwards causes lowering of the sliding support, on which the seat is installed, relative to the seat support. The first hinged arm continues beyond its hinged axis above the fixed support structure and ends with the back end, being hingedly connected to the back support, which is hingedly connected around the transverse axis with the seat support.

EFFECT: invention is aimed at more convenient arrangement of a user in any possible position occupied by the armchair, and at convenience of seat position adjustment.
