CHAIR SYSTEM WITH A SUSPENDED BALANCED INCLINATION SEAT ADJUSTABLE BY A BODY WEIGHT ONLY

摘要

The system has three longitudinal deformable parallelepipeds (B1-B3), and a flexible seat (A) suspended on a seat carriage and sliding at a level of knee and ankles on bars of the seat carriage. Two symmetric deformable quadrilaterals (P1, P2) support the seat and pivot freely with respect to a fixed base (C) to permit variable inclination of the seat, where the inclination is secured by stop pins.
