Double dome - swivel chair mechanism with magnification function for a controlled asymetric backrest inclination of a stretch-elastic hybrid chair shell

摘要

Fig. 1 shows the basic structure of such a chair with mechanics and the special elastic-elastic integrally reinforced shell 4 with the specially elastic-elastic zones 5, 8 and 7. Main components of the kinematic functional parts are the mechanical support 32, the mechanical assembly and the two to each other, by an elastic acting multi-plate clutch coupled Armlever 6, which at the same time depict the armrest, and just the elastic-elastic integrally reinforced shell. 4
