Definitions

  • the present invention is related to the field of furniture design and it concerns the furniture with improved construction that enables anatomically correct sitting in various sitting positions (from an upright to near-reclined).
  • the invention is related to a self-adjusting armchair that enables changes in sitting positions.
  • the existing armchairs can be divided in two groups:
  • This self-adjustment means changing the angle of back support into a new position that suits the new sitting position, without user's intentional activity (any manual adjustment or fixing) except spontaneous and unconscious: moving forward on the seat with simultaneous leaning backward on the upper part of the back support for more reclined sitting position.
  • a load on the seat diminishes or completely disappears.
  • the back rest attached to both sides of the armchair by elastic cantilever and rigid lever, with its lower part pulls under the user's back, while the upper part moves backward, thus changing the angle of back support in new position.
  • the seat of the armchair is hanged on the both sides of the armchair by elastic element, which is deformed when the seat is loaded, with its upper part pressing the upper part of the rigid lever, obstructing the rotation of the rigid lever (brake) which is attached on the other end to the back support and obstructs it's rotation too.
  • a part of the rotation in the rotation axle carries the elastic cantilever fixed into the sides of the armchair with one end and attached to the backrest with the other. This elastic cantilever also returns backrest to the upright position. Reducing the part of rotation in the rotation axle makes the real performance much easier.
  • Drawings depicts an armchair with self-adjusting backrest in various sitting position, from an upright (Fig. 1) to reclined (Fig. 2).
  • Integral parts of the armchair are: seat 1, back 2, sides 3 and 4 which are armrests, elements 5 and 6 for joining the sides and tightening the armchair.
  • Self-adjusting armchair can be made of various flexible materials (e.g. plywood, metal, artificial).
