Definitions

  • the present invention relates to a mechanism for chairs, in particular office swivel chairs, with a gas spring and an arrangement for height adjustment and with synchronously adjustable inclination of the seat and backrest, for which purpose a gas spring is also used.
  • the current chair position can be locked or unlocked by actuating the tilt adjustment arrangement. If the locking of the inclination adjustment is released, you can change the position of the backrest within an adjustment range by shifting your body weight, whereby the seat follows synchronously.
  • chairs equipped in this way you can move from a forward-inclined position (writing position ), through a middle position (basic position), to a backward-inclined position (relax position ) .
  • the present invention relates to the constructive Composition of a backrest and a seat shell in interaction with design features on upholstery for the backrest and the seat shell for mutual Fixation.
  • Mechanisms for swivel chairs with a synchronization of the Sequence of movements between the seat and the backrest where Ergonomically adequate positioning for every backrest inclination the seat is assigned are already in multiples Copies known (e.g. CH-A-629 945, CH-A-524 982, DE-C-29 40 250, DE-A-39 16 474, US-A-4 408 800, EP-B-0 592 369, WO 83/00610).
  • the more modern constructions also allow the seat and backrest to be inclined forward to move forward when working on a table flexed posture of the user, i.e. the underside of the thigh resting on the seat relieve pressure and effectively support the back area.
  • a such synchronous mechanism is known from AU-B-581 120.
  • An articulated strap extends from the seat support to the seat shell, considering their articulation point on the seat shell towards the front of the seat shell - before the pivot point lies on the seat support. Through the cross connection to The backrest takes on the front section with increasing load the seat shell also the supporting contact pressure of the Backrest against the user's hip area too.

  • the hinge plates run obliquely ascending to the front, whereby the axis of rotation between the hinge plates and the seat shell of the front edge the seat shell is closer than the axis of rotation between the hinged straps and the seat support.
  • the two housing shells are preferably made of die-cast aluminum, while the operating levers, the socket the coil spring, the hinged straps, the seat shell and the backrest are one-piece molded plastic parts.
  • the backrest cushion can be pushed onto the backrest and is by means of a clip that can be clipped into the backrest and Velcro fasteners. Also quick
  • the seat cushion is detachably attached to the seat shell.
