Swivel chair with reclining backrest, comprising four transversal axes for moving backrest and seat area

摘要

The chair is assembled of a telescopic column (16), of a stand (14,18) with rollers, a seat area (10), and a backrest (12) slightly bent in order to support the lower spine. The backrest (12) is joined with a first transversal axle (26) to the rear of the seat area (10) and can be swiveled around a second axle located above the first (26) and joined to the front of the seat area (10) with a system of two levers (30,36). Two more rotation axles facilitate a forwards motion of the seat area (10) when the occupant reclines against the backrest (12).
