Definitions

  • the invention relates to a chair, in particular an office chair.
  • a generic chair is from the EP 1 169 947 A1 known.
  • This chair has a front seat support part, in which a relative to this pivotable bearing part is arranged.
  • the tilt adjustment is made by a pivoting movement about a transverse to a main plane of symmetry of the chair hinge axis. This means that the known chair allows a user to adjust his sitting position forward or backward.
  • the invention has the object, a chair of the generic type such that a user individually adjustable by a user position and can be locked.
  • the essence of the invention is that an articulation of a bearing part on a front seat support part is designed as a pendulum bearing such that a pivoting of a seat together with a backrest both in a main plane of symmetry of the chair and from the main plane of symmetry out is possible.
  • the self-aligning bearing is designed as an elastic bearing with two elastic bushings, in particular rubber bushings, which are spaced from each other and arranged concentrically to a hinge axis of the self-aligning bearing.
  • a locking device In principle, the ability to pivot can be blocked or permitted. In addition, it is possible to preserve a set by the user, tilted forward or backward seating position by pressing the locking device, so that the user can permanently take this example, for him personally ideal seating position. In a locked arrangement of the chair, a lateral pivoting of the seating position is prevented, ie the seat is brought into a central position with respect to the main plane of symmetry. In particular, the locking device serves to lock an inclination of the seat forward. Due to the increased flexibility, in particular by the lateral pivoting of the sitting position, the chair according to the invention allows the user a more dynamic sitting.

  • From the piston rod 30 protrudes an actuating pin 31, by means of which a located in the gas spring valve can be actuated for length adjustment.
  • the piston rod 30 is connected by a thread with an actuator 32 to which the actuating lever 9 belongs.
  • This actuator is pivotally mounted between the side walls 14, 15 of the front seat support member 12 parallel to the pivot axes 20, 22, 28.
  • the actuating lever 9 is led out through a slot 33 in the associated side wall 16 of the rear seat carrier part 13, wherein this slot 33 is curved in such a way that its center coincides with the pivot axis 20.
  • the front and rear seat support part 12 and 13 are pivoted about the pivot axis 20 against each other, whereby on the one hand, the inclination of the seat 5 changes and on the other hand, the backrest support 6 is pivoted to the backrest 7.
  • This is a pivoting forward by an angle a, the in Fig. 7 is shown possible.
  • the angle a can be up to 10 °.
  • Such devices are referred to as so-called synchronous mechanisms. If the actuating pin 31 is not only briefly inserted into the piston rod 30 of the gas spring 27 to 27 to achieve a change in length of the gas spring and thus a change in the position of the seat 5 and the backrest 7, but if the actuating pin 31 for a long time in the Piston rod 30 is inserted, then the seat 5 can be tilted together with the backrest 7.
