Definitions
- the invention relates to a seat storage for an all-round elastically tiltable seat part of a seat device, in particular a joint combination for an office chair.
- a easy pivoting means that the seat part in a Pivoting direction according to the seating direction forward or can be tilted behind. Is the pivoting seat part with connected to a backrest, so is the pivoting of the Seat part coupled with the backrest. At a rigid Coupling of seat and backrest would be the latter always tilt at the same angle as the seat part. This is However, from the perspective of seating comfort usually not desired. To remedy this problem has been in the past a synchronous mechanism developed in the following below Reference to Figs. 3 and 4 (prior art) explained becomes.
- Fig. 3 shows a schematic side view on the left a normal Sitting position with horizontal seat and essentially vertical backrest.
- the backrest is opposite the vertical slightly inclined, but it is the seated person no problem is to lean slightly forward.
- the pivoted seat position is shown.
- the seat device is configured, for example, to that the backrest from an angle 0 to a Angle ⁇ is pivotable. To achieve the seating comfort the seat at maximum pivoting of the backrest less be pivoted by the angle ⁇ .
- the Synchronous mechanism provided 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 at a pivoting operation of the pivot angle of the seat for Swing angle of the backrest according to an angle ratio 1: x is related, where the parameter x for Office chairs is usually about 2 to 3.
- the synchronizing mechanism 10 ' (see Fig. 4A, B), which at the upper end a support column 41 'is mounted substantially comprises a housing 11 'for a lever mechanism to which a first Swivel arm 12a 'and a second pivot arm 12b', for adjustment cooperate the desired angular ratio, are articulated.
- the first pivot arm 12a ' forms a fork-shaped Cantilever and is connected to the backrest (not shown) rigidly connected.
- the second pivot arm 12b ' is on hinged upper end of the housing 11 'and serves as a carrier of the seat part (not shown).
- the lever mechanism for setting the angle ratio contain In the housing 11 ' is the lever mechanism for setting the angle ratio contain.
- the conventional synchronous mechanism has the disadvantage of limited use in seating devices with easy pivoting.
- a seat part For seating, it is also ergonomically useful, a seat part provide, relative to the foot structure in all directions tiltable, so that an active-dynamic seats guaranteed becomes.
- active-dynamic seating is from the utility model DE 295 16 794.7 a seat hinge 5, which is shown schematically in FIG. 5 (prior art) is.
- the seat hinge 20 ' provides the connection between a Support column (not shown) and a seat part (not shown) e.g. an office chair via a support part 21 'and a universally tiltable plate 22 'ago.
- On the upper side of the support part 21 ' is an upwardly curved Support surface 23 ', on the center by means of a screw 24' or a corresponding connection the plate 22 'attached is.
- the screw 24 ' is made of an elastic material and allows an all-round pivoting of the plate 22 'on the support surface 23 '.
- a limiter 25' in the form of an annular all-round projecting plate provided, consisting of an annular Carrier 26 'and a resilient support 27' (e.g. Rubber).
- Seat parts based on a joint according to FIG. 5 was previously limited to active-dynamic seating devices, which allow a healthy and ergonomic sense of sitting, for certain seating situations, in particular in the office sector, but may not provide the necessary comfort.
- the basic idea of the invention is a novel Specify seat storage, which consists of two basic components. These basic components include firstly a synchronous mechanism, their function in itself of the above technique is known and the constructive in the context of the present invention to the assembly with the second basic component is adapted.
- the second basic component essentially comprises an elastically tiltable joint on all sides, as it is also on its own from the active-dynamic seating devices is known.
- the seat part is not directly rigid attached but attached over a joint that is an all-round Tilting of the seat part relative to the synchronous mechanism guaranteed.
- the advantage of the combination according to the invention of a synchronous mechanism consists of a tiltable universal joint in their extended functionality. Furthermore, the new one Seating storage made available in commercial and technically tested in terms of their reliability components built up. Finally, the invention allows a simple conversion of an existing office chair with simple Pivoting to an all-round pivoting.
- the seat storage according to the invention is schematically, partially as a sectional view, illustrated in Fig. 1.
- the seat storage comprises the Synchronmechhanik 10 with the housing 11, the first pivot arm 12a and the second pivot 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 pivot arm 12a forms a Backrest approach over which the backrest (not shown) with the first pivot arm 11 is firmly connected.
- the seat 31 is mounted on top of the plate 22 of the hinge part 20 and comprises a designed in a conventional manner and padded component.
- the synchronizing mechanism 10 is preferably according to the Synchronmechhanik 10 'constructed as shown in FIG. 4.
- the second tilts Swivel arm 12b on which the support part 21 of the joint part 20th is mounted, less strong than the first pivot arm 12a.
- the tilting motion in whole or in part Inclination of the plate 22 relative to the support member 21 due the weight of the person or by additional effort compensate and thus take the desired seating position.
- the joint part 20 is preferably according to the conventional, constructed on all sides tiltable joint according to FIG.
- the position of the limiter 25 is set, in turn corresponding to an annular support 26 and a pad of elastic material (e.g., rubber) 27 exists.
- the elasticity of the support 27 serves above all a soft placement of the plate 22 on the limiter 25. Es may therefore alternatively be provided that the limiter 25 is made entirely of a rigid material while the Plate 22 has elastic properties.
- the plate 22 is Centered with an elastic connecting element on the itself attached to the top bulging support surface 23.
- Support part 21 and the second pivot arm 12 b formed integrally.
- the Fign. 2A-D show different pivot situations on one Seating device according to the invention, e.g. in the form of an office chair.
- the seat device comprises the seat assembly 30 and the Foot assembly 40, which over the (hidden) Wegteillagerung with the synchronizing mechanism 10 and the joint part 20 (see Fig. 1) are.
- the seat assembly 30 includes the seat portion or the Seat 31 and the backrest 32.
- the foot assembly 40 includes the Carrier column 41, which is for example gas pressure-spring-loaded, and a foot 42 with wheels 43.
- the seat portion 31 is corresponding the arrow directions in Fig. 2A by the inclinability of the joint part 20 with respect to the support column 41 pivotable, wherein in this pivoting movement, the position of the backrest 32 unchanged remains (see Fig. 2B).
- the pan is over an axis that is oriented perpendicular to the seating direction, so the synchronous mechanism is involved in the panning process, so the backrest 32 pivots with the seat part 31 (see FIG. FIGS.
- the invention is not on the seat storage for office chairs limited, but also applicable to other seating devices, the for the admission of single or several persons (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) of the limiter 25 can be moved in such a high position that a Inclination of the plate 22 with respect to the support part 21 excluded becomes. In this position, the adjusting ring 28 has equipped with the seat storage according to the invention Seating device the characteristics of a conventional, simple swiveling chair. This can be the site properties easily adapted to the respective requirements.
- the Adjusting the position of the limiter 25 with the adjusting ring 28 can also by another suitable, on the support part 21 height-adjustable mechanism (e.g., adjustable cuff or laterally cantilevered pins).
- the limiter 25 can also by another locking mechanism be replaced, in particular for fixing the Seat is set up. It can, for example, a lamellar clamp or a wedge lock may be provided.
