Definitions

  • the present invention relates to a chair with at least one seat plate and at least one arranged on at least one support arm backrest, wherein the seat plate is supported on at least one connected to the support arm elongated bending spring and the bending spring is arranged so that it is transverse to the load on the seat plate Elongation is elastically deflectable.
  • so-called synchronous mechanisms are known for seating furniture, in particular office chairs. These allow the backrest of the user simultaneous pivoting of the backrest and the seat takes place, wherein the pivot angle of the backrest is greater than that of the seat.
  • the DE 196 07 136 shows an office chair with such a synchronous mechanism, which requires a relatively large number of pivot or pivot joints and a longitudinally acting spring. Although the construction revealed there ensures good ergonomics, the construction of this chair is relatively complex.
  • an office chair is known in which an elongated bending spring is deflected transversely in the form of a spring package.
  • This spring assembly is bolted to a carrier housing, which in turn is connected to the support arm supporting the backrest via a pivot joint. Also, this construction is relatively expensive in terms of the number of items and thus the cost of assembly.
  • a chair which has a support, a seat plate and on at least one pivotable relative to the support arm a backrest.
  • the seat plate is supported by a shaft of a bearing device at free ends of two support arms rotatably fixed on the support arm, longitudinally extended.
  • the bending springs are arranged so that it deflects elastically at a pivoting of the backrest due to a load on the seat plate or the backrest transversely to its longitudinal extent.
  • the bearing device allows a relative movement against the spring force of the spiral spring between the Seat plate and the support with a vertical position in the operating position of the chair component, since the shaft is guided in a slanted slot.
  • the spiral spring is not the only suspension of the synchronous mechanism of this chair.
  • a gas cylinder acts between the support and the back support. With the gas cylinder, the inclination of the back is adjustable.
  • To the shaft an eccentric is formed, which can be rotated with a set screw. The eccentric presses on the free end of the spiral spring and this can stand out from the shaft, so that this only alslastet indirectly via the eccentric on the spiral spring.
