Definitions

  • the invention relates to a chair, in particular an office chair, according to the preamble of claim 1.
  • a generic chair is known from EP 0 584 620 A1.
  • This has a front seat support part in which a pivotable relative to this Bearing part is arranged. By pivoting the The inclination of the seat support in relation to the chair column can be adjusted.
  • to Locking this pivoting movement is a plate pack locking device provided, in which plate packs jam each other. The locking is thus carried out along the swivel direction Friction.
  • This has the disadvantage that larger locking devices acting forces, e.g. by heavy users, a complete locking cannot be guaranteed.
  • the object of the invention is a chair the generic type in such a way that the seat together with the backrest regardless of the given inclination adjustment the synchronous mechanism in different inclination positions can be determined as effectively as possible, in particular through the synchronous mechanism given angle of inclination of the seat and backrest within one To be able to change the adjustment range.
  • the essence of the invention is to provide a rack locking device.
  • the advantage is there in that the locking along the pivot direction is not through Friction, but is done by positive locking. That way is one particularly effective locking possible.
  • An office chair shown in Fig. 1 has a base frame 1, which Rollers 2 is supported against the ground.
  • On the base 1 is one height-adjustable chair column 3, covered by a bellows 3a, at the upper end of a seat support 4 is releasably attached, on the again a padded seat 5 is attached.
  • On the seat support 4 is a attached essentially upward extending backrest support 6, at the upper end of a backrest 7 is attached.
