Definitions

  • the invention relates to a synchronous mechanism for a correlated seat-backrest movement of an office chair, with a placeable on a chair column base support, a seat support and a backrest support.
  • synchronous mechanism assemblies are understood in the seat base of an office chair, which provide for a coupled, a certain relative movement of the seat and backrest with each other bringing kinematics.
  • On the seat support of the usually provided with a padded seat seat of the office chair is mounted.
  • the backrest support which extends in a conventional manner from the actual synchronizing mechanism to the rear, carries on an upwardly extending arm, the backrest of the office chair.
  • Seat support and backrest support are usually coupled so articulated in such self-adjusting synchronous mechanisms that a pivoting movement of the backrest to the rear a lifting movement of both the rear, as well induced the front of the seat so that the entire seat is raised, or it is only the front portion of the seat raised, while the rear portion of the seat is immutable in height.
  • Such self-adjusting synchronous mechanisms are often constructed comparatively complicated, consist of a large number of interacting components and / or are expensive to install. Examples of self-adjusting synchronous mechanisms are in WO 2009/103389 A1 and DE 41 18 570 A1 specified.
  • a synchronous mechanism in which a pivoting movement of the backrest to the rear has a lifting movement of the front portion of the seat as well as a lowering movement of the rear portion of the seat result in WO 2014/166804 A1 described.
  • An object of the present invention is to provide a structurally particularly simple self-adjusting synchronous mechanism. This object is achieved by a synchronous mechanism according to claim 1.
  • Advantageous embodiments of the invention are specified in the subclaims.
  • An idea of the invention is to reduce the number of coupling elements, in particular the number of seat support and backrest support connecting elements, thereby achieving a particularly simple structural design of the mechanism, without sacrificing the desired functionality of a synchronous mechanism.
  • An idea of the invention moreover, to provide a deviating from the usual lifting movement of the seat seat movement, in which nevertheless the so-called "shirt extraction effect" is avoided. This will be a special achieved high seating comfort, without having to resort to more expensive and expensive solutions.
  • the backrest support both pivotable about a transverse axis and thus defining the main pivot axis of the mechanism with the Base support, as well as with the seat support directly, ie directly and without the interposition of an additional component, articulated such that a pivotal movement of the backrest from a basic position into a pivoted backward position an immediate lowering movement of the chair longitudinal direction seen rear portion of the seat carrier to the rear induced bottom and the seat support is pivotally connected to the base support via a hinged to the seat support and the base support coupling element such that during the pivotal movement of the backrest from the basic position in the pivoted back position immediate lifting movement of seen in chair longitudinal direction front portion of the seat support takes place at the top back and a spring mechanism is provided for adjusting the pivoting resistance of the backrest, which has at least one spring element connecting the base support to the backrest support.
  • the user's weight directly affects the swing resistance felt by the user.
  • a light user must overcome a significantly lower swing resistance when pivoting than a heavy user.
  • the synchronous movement of the seat support can be adapted individually to the demands made on the chair.
  • adjustable how much the seat support tends during pivoting of the backrest support or how much the seat support moves against the base support during a pivotal movement of the back horizontally in the chair longitudinal direction moves backwards.
  • the special synchronous movement of the mechanism according to the invention is achieved in a particularly simple manner that is defined by the positions of the articulation points of the backrest support on the base support on the one hand and on the seat support on the other hand, a rigidly connected to the backrest support or formed as an integral part of the backrest support coupling element , In other words, no reciprocally freely pivotable coupling element is required between the backrest support and the seat support. Instead, the backrest support itself serves as a coupling element.
  • a particularly suitable coupling geometry and a resulting synchronous movement is achieved in that the pivot point of the front coupling element is seen on the seat support in the seat longitudinal direction in each position of the backrest support in front of the articulation point of the front coupling element to the base support.
  • This is combined in a preferred embodiment of the invention in that the pivot point of the rear coupling element seen on the seat support in the seat longitudinal direction in each position of the backrest support behind the pivot point of the rear coupling element to the base support.
  • the front coupling element is connected to the seat support via a pure rotary joint and not about in combined rotary / sliding joint.
  • the present synchronous mechanism is characterized in that it is particularly flat, so that a corresponding assembly requires very little space. This is true even if to support or influence the swivel resistance and / or to prevent the backrest tilts uncontrollably backwards and for a safe retrieval of the backrest from the pivoted position to the initial position as soon as the user no longer burdened the backrest ,
  • a spring mechanism is provided with one or more spring elements, since the spring mechanism can be designed such that the at least one spring element connects the base support with the backrest support, without the addition of the already provided housing volume of the base support out further additional space required. This is especially true when the spring element is connected to the front portion of the base support and the pivot point of the backrest support to the seat support and characterized comparatively flat lying inside the assembly is arranged.
  • the at least one spring element need only be made comparatively weak, so that act on the components of the mechanics only small spring forces, resulting in a compared to conventional mechanics significantly reduced stress on the components.
  • no spring forces act on the seat support, since this is moved exclusively over the backrest support.
  • the seat support of the backrest support more specifically of the attacking at the pivot point on the seat support coupling element of the backrest carrier, taken, whereby the transmission of the forces acting on this pivot point, while the seat support connecting to the base support coupling element only one Movement mitticiannde, but no force-transmitting effect has.
  • the spring mechanism comprises means for adjusting the bias of the at least one spring element, wherein the adjusting means comprise a Verstellgriff, for the adjustment of the bias from a built-in base plate in the rest position in an operating position the base carrier is pulled out.
  • Such an adjustment handle is particularly useful when the at least one spring element is a helical tension spring and the adjusting means comprise actuatable adjusting elements by means of the adjustment handle, by means of which the distance between the spring ends of the helical tension spring is variable.
  • the adjustment of the bias can be done using simple adjustment by rotating the adjustment handle to the spring axis. Overall, this results in a realizable with a few components and very little space required spring force adjustment.
