Definitions

  • the invention relates to an office chair, with a vertical column extending from a base, a seat plate, a backrest and a cantilever projecting from the upper end of the column, at the front end of which the seat plate is supported in a first transverse pivot axis, one in the central region of the Cantilever arm mounted in a second transverse pivot axis, which extends along the seat plate to the backrest and carries this, a support bearing which displaceably connects the carrier and the seat plate and a spring for supporting the carrier with respect to the column.
  • the function of such an office chair is essentially based on the pivotable support and a spring supporting the support on the column.
  • the carrier supports the rear end of the seat plate and also the backrest and enables a simultaneous movement of these two parts when deflected in an ergonomically appropriate transmission ratio.
  • the only figure is a side view of a chair according to the invention.
  • a pedestal 10 extends from a column 12 directed vertically upwards. At the upper end of the column, a forward, slightly upwardly inclined arm 14 is attached.
  • terms such as front, back, side, etc. refer to the normal sitting position of a person sitting on the chair.
  • first horizontal, transverse pivot axis 16 which establishes a connection between the boom 14 and a seat plate 18 so that the front region of the seat plate is pivotally supported on the boom.
  • the pivot axis 16 can be formed, for example, by rubber blocks, which allow sufficient deformation in view of the relatively small pivot angle of the seat plate 18.
  • a curved support 22 extends from the central region of the boom 14 in a second, horizontal, transverse pivot axis 20, which initially runs backwards below the seat plate 18 and then upwards to the rear of a backrest 24.
  • the carrier 22 In the front and middle area of the chair, the carrier 22 is double-armed. In each case one of the two congruent arms mounted in the pivot axis 20 runs on one side of the arm 14 and the upper end of the column 12. Behind the column 12, the two arms can converge again.
  • the sleeve 34 In the upper area of the column 12, it is surrounded by a displaceable sleeve 34 which rests on the upper end of the coil spring 26.
  • the sleeve 34 has a recess, not shown, for the passage of the boom 14 in the front region. Otherwise, the sleeve 34 has on its lower side a helical recess 36 which, like the recess 32 in the lower support ring 28, receives the outgoing end of the coil spring 26.
  • the two arms of the carrier 26 run past the opposite outer sides of the sleeve 34 and are in one with the sleeve third, horizontal, transverse pivot axis 38 pivotally connected.
  • the carrier 22 is supported on the coil spring 26 via the sleeve 34.
  • the rear end of the seat plate 18 is slidably supported on the carrier 22.
  • the seat plate 18 and the backrest 24 are connected to one another in the region above the rear end of the seat plate 18 in a flexible connecting line 40.
  • the rear region of the seat plate 18 is supported on the carrier 22 in a displaceable manner via a sliding guide 42. This gives the seat plate and backrest a certain degree of mobility with respect to the other parts of the chair mechanism, which on the one hand blocks the various movements of the chair mechanism and on the other hand offers a comfortable range of motion even when the chair is in a fixed position.
