Method of conjugating seat and tension bar in transformable soft furniture, intended to move seat

FIELD: human vital needs satisfaction.

SUBSTANCE: tension bar is located behind the vertical seat panel located on top of the seat frame elements, on which the seat supports are fixed. The tension bar is coupled with the seat with the possibility of removing a part of the tension bar due to the vertical panel of the seat. At least one return element is located behind the vertical panel of the seat, which is conjugated with the seat and the tension bar so that the return element stretches the tension bar over the vertical seat panel.

EFFECT: possibility to move the seat by means of the tension bar in the transformed soft furniture when it is possible to conceal the placement of this tension bar at a time when it is not used.
