Definitions

  • the invention relates to a chair comprising a base structure, a seat, a backrest and an elastic device that allows a rearwards oscillation of the backrest under the action of a rearwards thrust applied by the user, and in which the elastic device applies to the backrest an elastic force which tends to thrust the backrest towards a resting position against the rearwards thrust applied by the user.
  • the backrest 16 is preferably constituted by a monolithic piece of injection moulded plastic material and is connected to the portion supporting the backrest 24 by means of an elastic device 26.
  • the elastic device 26 comprises a stationary transverse element 28 fastened, at each of its ends, to the corresponding portion supporting the backrest 24.
  • the transverse element 28 is preferably constituted by a metal bar, for example made of steel, having in a plan view an arched shape with concavity oriented towards the front part of the chair.
  • the transverse element 28 has a rectangular transverse section and has at each end a fastening portion 30 fastened to the corresponding portion supporting the backrest 24.
  • the fastening portion 30 is preferably constituted by a downwards bent portion of the transverse element 28.
  • the fastening portion 30 is fastened to a bushing 32 by means of a transverse pivot 34.
  • the bushing 32 is inserted and fastened in the open upper end of the supporting portion of the backrest 24.
  • the bushing 32 is formed in two parts and is glued to the support portion 24.
