Definitions

  • the invention relates to a device for seat tilt adjustment of a chair, especially for office and swivel chairs or armchairs, and such a chair.
  • High-quality office chairs are often also equipped with a so-called synchronous mechanism, by means of which the seat and the backrest of a chair in a reclined seated person in a correlated movement together to pivot backwards and downwards.
  • a chair is z. B. in the DE 196 40 564 A1 described.
  • a seated person is referred here from a forward posture by shifting weight into a reclining posture guided, in which a more relaxed sitting is possible.
  • the seated person In the forward position, the seated person typically assumes a nearly horizontal seating position so that the upper body forms a substantially right angle with respect to the thighs.
  • the pelvis has the tendency to turn backwards in this sitting posture, so that the natural S-shape of the spine becomes a "round-back posture", which permanently burdens the intervertebral discs in the lumbar spine.
  • an adjusting mechanism is provided with which the seat between a horizontal position and a slightly forward inclined position can be adjusted by z. B. about usually simple mechanical elements, the rear seat edge by about 2 to 4 cm about a pivot point, which is typically located in the front region of the seat is raised.
  • This adjustment of the seat angle can be made in various ways:
  • German utility model DE 75 32 885 U1 is described a chair in which the seat tilt is adjusted by a gas spring, which acts in the rear part of the underside of the seat.
  • the seat inclination is here via a simple hinge principle, which runs essentially in the front or middle part transversely under the seat, realized.
  • this seat adjustment dispenses with complicated adjusting mechanisms, such a gas spring is comparatively expensive.
  • the particular problem is that the adjusting mechanism, and in particular its (gas pressure) springs in the loaded state must absorb the entire load of a person sitting on the seat.
  • the corresponding (gas pressure) springs must be sized accordingly large, on the one hand to be able to record a very large weight.
  • these (gas pressure) springs may not lose or lose their spring characteristics over time.
  • the special claim is therefore that the adjustment mechanisms and thus also the corresponding (gas pressure) springs are designed for the entire life of such a chair, without the elastic properties are significantly lost in this period.
  • the present invention has the object, in a chair, a simple and in particular the most cost-effective way to allow seat tilt adjustment.
  • this object is achieved by an armrest with the features of claim 1 and / or by a chair having the features of claim 15.
  • a device for seat tilt adjustment of a chair in particular for office and swivel chairs or chairs, with a spring-loaded guide lever having a resilient element which is fastened to a seat and which exerts a substantially vertical spring force in the tensioned state on the guide lever at least one attachable to the seat, vertically aligned guide rail having internally a substantially vertically extending toothed rail, with a gear which is coupled via an articulated connection with the guide lever such that a gear portion of the gear inside the guide rail is arranged to be vertically movable, so that at each seat inclination Always first teeth of the gear portion engage in second teeth of the toothed rail.

  • the underlying realization of the present invention is that conventional (gas pressure) springs for adjusting the seat height have a dual function.
  • This dual function includes on the one hand a return function, via which an inclined seat in the unloaded state is brought back to its original position.
  • this (gas pressure) spring must be designed so that it can absorb the entire force acting on the seat even in the loaded state.
  • the return function is further provided by a resilient element.
  • a resilient element for this functionality of retrieving the seat to its initial position, it is not necessary to provide a very large, excessively sized spring. Rather, a resilient element with comparatively sufficient here low spring force.
  • the second functionality that is, the inclusion of the force acting on the seat in the loaded state, according to the invention is no longer collected on the elastic element, but rather on engaging in corresponding toothed rails gears.
  • This toothed rail is provided according to the invention in a specially provided guide rail.
  • a respective toothed wheel is here arranged to be movable vertically in a guide rail assigned to it, wherein the corresponding toothed rails likewise have a vertical orientation within these guide rails. In this way, a very effective and beyond a mechanically very stable seat tilt adjustment is possible.

  • the solution according to the invention thus offers, on the one hand, a mechanically extremely stable and safe seat tilt adjustment and, on the other hand, a very cost-effective adjusting mechanism.
  • the gear is designed as a cam-like gear.
  • This gear thus has a gear portion and a lever portion, wherein the lever portion protrudes in the form of a cam-shaped formation of the gear.
  • a specially provided bore is provided, on which the guide lever is articulated via an articulated connection.
  • this guide lever is coupled to the axis of a circular gear, for example via an axial connection.

  • This spring is preferably arranged within a sleeve-shaped or at least partially enclosed portion of the guide lever and thus protected from an external mechanical or otherwise damaging influence. Conceivable, of course, would be other types of elastic elements.
  • the spring force of the resilient element is dimensioned such that, for example, in a horizontal sitting position, the resilient element has a greater spring force than at a tilted relative to the horizontal seating position.
  • a maximum spring force in the horizontal sitting position of about 45 N caused by the resilient element, whereas this spring force at a z. B. by a few degrees inclined seating position only about half, for example, 25 N is.
  • the resilient element is formed such that it has a maximum spring tension and thus a maximum spring force at maximum seat inclination.
  • the z. B. corresponds to the initial position of the seat, the elastic element is not or only slightly stretched.
  • the seat tilt adjustment is stepped.

  • an actuation device which can be attached to the seat which, when actuated, makes possible an adjustment of the seat inclination.
  • the actuating device further has a locking device which fixes the guide lever in the unactuated state against the seat and thus a movement of the guide lever in the horizontal direction prevented.
  • the actuator typically has an actuation button (eg, a button, a lever, a knob, etc.).

To lock this spring-loaded pin is inserted into corresponding ⁇ rretienciesEnglish 11, the seat and the guide lever at non-actuated button.
  • stepless adjustment of the seat tilt is much more complex than the stepped seat tilt adjustment, since a greater effort in terms of the function of the locking device and the gear functionality must be made.

  • a minimum stop of the seat inclination can be predetermined via a second stop.
  • two guide rails are provided.

  • This transverse coupling device is formed, for example, as a crossbar, which are fitted in specially provided for this purpose central recesses of the two gears. This crossbar ensures that a force acting on the seat on both sides of the cross bar of the respective gears is uniformly transmitted to the respective associated guide rails.
