Definitions

  • the invention relates to a seat part storage for all sides elastically inclinable seat part of a seat device, in particular an articulated combination for an office chair.
  • Fig. 3 shows a normal side view in a schematic side view Sitting position with horizontal seat and essentially vertical backrest.
  • the backrest is opposite the vertical slightly inclined, being the seated person, however no problem is to lean forward slightly.
  • the pivoted sitting position is shown.
  • the seat device is set up, for example, that the backrest from an angle 0 to one Angle ⁇ is pivotable. To achieve seating comfort should the seat is less when the backrest is swiveled to the maximum than be pivoted by the angle ⁇ .
  • the Synchronous mechanism provided, which in Fig. 4A in schematic Side view and shown in Fig. 4B in a schematic plan view is.
  • the synchronous mechanism is designed so that a pivoting process of the pivot angle of the seat to Backrest swivel angle according to an angle ratio 1: x is related, with the parameter x for Office chairs are usually about 2 to 3.
  • the synchronous mechanism 10 ' (see. Fig. 4A, B) that at the upper end a support column 41 'is essentially comprised a housing 11 'for a lever mechanism on which a first Swivel arm 12a 'and a second swivel arm 12b' for adjustment the desired angular ratio interact, are articulated.
  • the first swivel arm 12a ' forms a forked one Outrigger and is with the backrest (not shown) rigidly connected.
  • the second swivel arm 12b ' is on upper end of the housing 11 'pivotally hinged and serves as a carrier of the seat part (not shown).
  • the lever mechanism for adjusting the angle ratio In the housing 11 ' is the lever mechanism for adjusting the angle ratio contain.
  • the conventional synchronous mechanism has the disadvantage of one restricted area of application for seating devices with easy pivoting.
  • a seat joint from the utility model DE 295 16 794.7 known, which is shown schematically in Fig. 5 (prior art) is.
  • the seat joint 20 ' provides the connection between one Support column (not shown) and a seat part (not shown) e.g. an office chair over a support part 21 'and a plate 22 'which can be tilted on all sides.
  • On the top page of the support part 21 ' is an upwardly curved one Support surface 23 ', on the center by means of a screw 24' or a corresponding connection plate 22 'attached is.
  • the screw 24 ' is made of an elastic material and allows the plate 22 'to pivot on all sides the bearing surface 23 '.
  • a limiter 25' in the form of a ring on all sides cantilevered plate provided which consists of an annular Carrier 26 'and an elastic pad 27' (e.g. from Rubber).
  • Other features and modifications of the seat hinge 20 ' are in the above Utility model described, the content of which hereby explicit reference is made.
  • the use can be tilted on all sides 5.
  • Seat parts based on a joint according to FIG. 5 was previously limited to active-dynamic seating devices, which enable healthy and ergonomically sensible sitting, for certain seating situations, especially in the office area, but may not offer the necessary comfort.
  • the basic idea of the invention is a novel one Specify seat part storage, which consists of two basic components.
  • these basic components include a synchronous mechanism, their function per se from the above technique is known and constructive within the scope of the present invention the assembly with the second basic component is adjusted.
  • the second basic component essentially comprises a joint that can be tilted elastically on all sides, just like it by itself from the active-dynamic seating devices is known.
  • the seat part is not directly rigid attached, but attached via a joint that is all-round Tilting of the seat part in relation to the synchronous mechanism guaranteed.
  • the seat part storage according to the invention is schematic, in part as a sectional view, illustrated in Fig. 1.
  • the seat part storage comprises the synchronizing mechanism 10 with the housing 11, the first swing arm 12a and the second swing arm 12b, and the hinge part 20 with the support part 21, the plate 22, the Limiter 25 and the collar 28.
  • the lower end of the housing 11 is attached to the support column 41 of the seat device.
  • the free end of the first swivel arm 12a forms one Backrest over which the backrest (not shown) with the first swivel arm 11 is firmly connected.
  • the seat 31 is attached to the top of the plate 22 of the hinge part 20 and includes a designed in a conventional manner and padded component.
  • the synchronous mechanism 10 is preferably in accordance with the synchronous mechanism 10 'constructed according to FIG. 4.
  • the second inclines Swivel arm 12b on which the support part 21 of the joint part 20th attached, less strong than the first pivot arm 12a.
  • the second swivel arm 12b tilts accordingly the support part 21.
  • Inclination of the plate 22 due to the support part 21 due of the person's own weight or through additional effort compensate and thus take the desired seating position.
  • the hinge part 20 is preferably according to the conventional, 5 tiltable joint constructed according to FIG.
  • the position of the limiter 25 is set, which in turn consists of an annular carrier 26 and a pad made of elastic material (e.g. rubber) 27 exists.
  • the elasticity of the pad 27 mainly serves a soft placement of the plate 22 on the limiter 25. It can therefore alternatively also be provided that the limiter 25 is made entirely of a rigid material, while the Plate 22 has elastic properties.
  • the plate 22 is in the middle with an elastic connecting element on the upwardly arching bearing surface 23 attached.
  • Support part 21 and the second pivot arm 12b are integrally formed.
  • the figures 2A-D show different panning situations on one seat device according to the invention, e.g. in the form of an office chair.
  • the seat assembly includes the seat assembly 30 and the Foot structure 40 with the (hidden) seat part bearing the synchronous mechanism 10 and the joint part 20 (see FIG. 1) connected are.
  • the seat assembly 30 includes the seat part or the Seat 31 and the backrest 32.
  • the foot structure 40 includes the Carrier column 41, which is gas-pressure-sprung, for example, and a base 42 with wheels 43.
  • the seat part 31 is corresponding the arrow directions in Fig. 2A by the inclinability of the joint part 20 can be pivoted relative to the support column 41, the position of the backrest 32 unchanged during this pivoting movement remains (see Fig. 2B).
  • the pivoting takes place around an axis that is aligned perpendicular to the direction of the seat, so the synchronous mechanism is involved in the swiveling process, so that the backrest 32 pivots with the seat part 31 (s. Fig. 2C, D).
  • the invention is not based on the seating of office chairs limited, but also applicable to other seating devices, for the admission of one or more people (System seating) are designed.
  • a particular advantage of the invention is that with the adjusting ring 28 of the joint part 20 (see FIG. 1) the limiter 25 can be moved into such a high position that a Inclination of the plate 22 relative to the support part 21 excluded becomes.
  • the collar 28 has equipped with the seat part storage according to the invention
  • Seat device the features of a conventional, simple swivel chair. So that the seating characteristics simply be adapted to the respective requirements.
  • the Setting the position of the limiter 25 with the collar 28 can also by another suitable, on the support part 21 height adjustable mechanism (e.g. adjustable cuff or laterally projecting pins) can be implemented.
  • the limiter 25 can also by another locking mechanism to be replaced, in particular to fix the Seat is set up.
  • it can be a lamella clamp or a wedge lock can be provided.
