FIELD: movable joint designed for construction of seat, in particular, arm-chair, and adapted for positioning between seat and its support.

SUBSTANCE: joint has at least two members adapted for limited rotation with respect to one another between two extreme positions for enabling inclination of seat due to movement of user's weight, and two outer members pivotally positioned for rotation relative to middle member. Rotation pins between two outer members and middle member are offset with respect to one another in horizontal direction. So, joint may be set in stable inclined state between two extreme positions. Joint of such construction allows user to adjust it and return to initial position when armchair is not used.

EFFECT: compact and simplified construction, and increased strength of movable joint.
