Office support chair - has vertical support column, seat, back-rest and adjustment mechanism with links, transverse axles, support plate and column head

摘要

The chair has a vertical support column (12), seat (16), back rest (36), and adjustment mechanism. The seat panel (16,18) is supported on the column by a link (20,22) muonted in transverse axles (24,26;28,30) movable at both ends. The link runs beneath the seat to the front and back and rests on the top of the column. The back link (22) extends up and back beyond its connection with the seat and has a first part (32) running back under the seat's back end, and a second part (34) rising behind the seat and forming an attachment for the back rest. The column top widens out into a head (14). A rigid support plate (18) under the seat joins the seat to the links. ADVANTAGE - The chair's position can be adjusted between an upright and a backward tilting position not only by displacing the body weight, but also by placing the legs on the floor or the hands on the desk.
