Definitions
- the invention relates to a seat device.
- Usual seat devices include the actual seat element, which is connected to a stand element via a support element. With the help of the stand element, the seat device can be set up on a corresponding stand surface.
- the seat element rotatably on the support element, so that a user sitting on the seat device can turn to the right or left. It is also known to enable the seat element to pivot, in particular to the rear, if the seat element has a backrest.
- the various movements of the seat element are usually realized with the aid of an assembly provided between the seat element and the support element, which is referred to as the “seat mechanism” and for this purpose often has a complicated structural design. This is particularly the case with office chairs and with other seating devices with similar functional properties.
- An object of the present invention is to provide a seat device in which a defined rotation and pivoting movement of the seat element is made possible without a seat mechanism functional unit having to be arranged between the seat element and the support element.
- the seating device comprises a combined rotating and swiveling device for rotating and swiveling an assembly of the seating device, this assembly comprising the seat element of the seating device, and wherein the rotating and swiveling device is arranged remote from the seating element of the seating device, namely near a base of the seating device .
- the rotating and swiveling device is designed in such a way that, regardless of the rotational position of the assembly, a swiveling movement of the assembly is only possible in one direction with respect to this assembly, with a stand element that can be set up on the base, with a support element connected to the stand element and with a seat element carried by the support element, the rotating and pivoting device connecting the stand element to the supporting element and the supporting element and the seat element being parts of the rotatable and pivotable assembly, the rotating and pivoting device having a base support and a pivoting head connected to the supporting element , wherein the base support is rotatably mounted on the stand element about an axis of rotation and wherein the pivot head is connected to the base body by means of a pivot axis, about which pivot axis the pivot head can be pivoted relative to the base body, characterized in that the rotation and pivoting vo direction has at least one spring element for influencing the pivoting resistance of the rotatable and pivotable assembly, which engages at least one spring element on
- a first basic idea of the invention is to arrange a rotating and swiveling device for rotating and swiveling the seating element away from the seating element of the seating device, namely near a standing surface of the seating device.
- a seat mechanism functional unit arranged between the seat element and the support element for realizing the rotating and pivoting device is therefore no longer required.
- the rotating and swiveling device is thus provided on or in the stand element or in any case in the vicinity of the stand element, it is located in the lower region of the support element, preferably at the lower end of the support element.
- the support element is preferably firmly connected to the seat element. Only the stand element remains motionless.
- the seating device can be any piece of seating, in particular a chair.
- the seating device can also be designed as an armchair, stool, etc.
- the seat element can, for example, be a seat support provided with upholstery with or without a backrest or a seat shell comprising a seat and backrest. But any other design of the seat element is also conceivable. Thus, even if this is not necessary for realizing the rotating and swiveling movement, the seat element can nevertheless have a seat mechanism functional unit, with the aid of the rotating and swiveling movement provided according to the invention, further movements of the seat element can be realized.
- the support element can be, for example, a pedestal that can be made height-adjustable.
- the support element can be connected in one piece to the seat element.
- differently shaped support elements can also be used, for example V-shaped or U-shaped support elements or the like, which are connected to the seat element at several spaced apart points.
- the support element preferably always has a defined lower end in the sense of a lower end point, which is connected to the stand element via the rotating and pivoting device.
- the stand element is preferably a stand. This can be designed as a round or square plate or as a star base with three, four, five legs, etc.
- the seat element together with the support element, is rotatably mounted in the fixed base with the aid of the combined rotating and pivoting device, the axis of rotation preferably being the central longitudinal axis of the support element or the axis of rotation extending in the longitudinal direction of the support element.
- a second basic idea of the invention is to design the combined rotating and pivoting device in such a way that pivoting of the support element and thus of the rotatable and pivotable assembly, including the seat element, is only possible in a single defined direction. As a result, the entire assembly is tilted in the correct direction above the base. At the same time, a rotation of the support element is possible without changing the permissible pivoting direction. In other words, the pivoting direction is fixed relative to the seat element. Regardless of how far a user of the seat device has turned to the right or left, pivoting is therefore only possible to the rear, e.g. towards the backrest. An unintentional tilting of the seat element to the right or left, as would otherwise be feared in the twisted state, is thereby reliably avoided.
- a chair 1 with an upholstered seat 2 and an upholstered backrest 3 is in Fig. 1 shown.
- Seat 2 and backrest 3 are firmly connected to one another and form the seat element as a movement unit.
- This seating element is carried by a chair column 4 serving as a supporting element.
- the chair column 4 is rotatably and pivotally connected to the seat 2.
- the chair column 4, seat 2 and backrest 3 thus form a rigid assembly 5.
- This assembly 5 is as whole rotatable and swiveling.
- a combined rotating and swiveling device 6 is used, which is arranged away from the seat 2, namely near a standing surface 7 of the chair 1.
- the rotating and swiveling device 6 is attached to the lower end 8 of the chair column 4 and is connected to the chair column 4 so as to be non-rotatable and pivotable.
- the rotating and swiveling device 6 is connected to a stand 9, which can be set up on the stand 7 and serves as a stand element, which is designed here as a plate.
- the rotating and pivoting device 6 is rotatably mounted in the base 9.
- An axial bearing 11, which is described in more detail below, is used for this purpose and can be designed as a plain bearing or roller bearing.
- a differently shaped support element can also be used, for example a V-shaped or U-shaped support element, as in FIG Fig. 2 outlined.
- a three-legged or multi-legged stand 9 can also be used instead of a plate, see Fig. 2 .
- Common to all support elements is a lower end point 8 for connection to the rotating and swiveling device 6.
- the stand 9 has, as in Fig. 3 depicted in more detail, a central bearing receptacle 12 for the rotating and pivoting device 6.
- the circular bearing receptacle 12 has on the inside a bearing shoulder 13 running around the receiving edge, which serves to form the axial bearing 11 for the rotating and pivoting device 6.
- a roller bearing is shown symbolically.
- a tapered roller bearing is preferably used since this is self-centering.
- the rotating and swiveling device 6 comprises a base support 14 and one arranged at the lower end 8 of the chair column 4 Swivel head 15, see Fig. 3 .
- the base support 14, which is U-shaped in cross section, is rotatably mounted on the base 9 about an axis of rotation 16, see also Fig. 4 , wherein the rotational movement is indicated by arrows 17.
- the axis of rotation 16 extends in the longitudinal direction 10 of the chair column 4 and enables the assembly 5 to be rotated in a predetermined range of rotation angles, preferably a 360 ° rotation.
- the base support 14 lies with its correspondingly designed support shoulder 18 on the bearing shoulder 13 of the pedestal 9.
- the base support 14 is fixed in the center of the stand 9 by means of a suitable fastening (for example in the manner of a pull-out protection), an additional central bearing point 19 for the base support 14 being provided on the stand 9 at this point.
- the base support 14 in turn has a pivot mount 21 in the center for receiving the pivot head 15.
- the pivot head 15 is either, as in the case outlined, connected in one piece to the chair column 4, or else the pivot head 15 has a corresponding cone mount for the chair column 4 (not shown).
- the swivel head 15 is articulated to the base support 14 via a horizontal swivel axis 22, see Fig. 4 .
- the pivot axis 14 can be a fixed or a pivoting pivot axis. In the non-pivoted state of the assembly 5, the pivot axis 14 runs perpendicular to the axis of rotation 16.
- the pivot axis 14 also serves as a connecting element of these two main components of the rotating and pivoting device 6. This ensures that the base support 14 and pivot head 15 always rotate together and together. Thus, the pivot axis 22 serving as the connecting axis ensures that the entire rotating and pivoting device 6 rotates.
- the swivel head 15 can be in the swivel receptacle 21 of the base support 14 from a non-swiveled basic position, as in Fig. 5 shown in a most pivoted pivot position, as in Fig. 6 shown.
- the pivot head 15 can be pivoted about this pivot axis 22 in a single defined pivot direction 23 relative to the non-pivotable base body 14.
- the swiveling direction 23 of the swiveling head 15 and thus the swiveling direction 23 of the entire assembly 5 thus always refer to the base support 14.
- the swiveling movement always takes place in a single defined direction 23, radially with respect to the chair column 4, relative to the seat 2. According to the invention thus the pivoting movement takes place regardless of the current angle of rotation always in the desired direction 23, preferably to the rear, i. H. in the direction of the backrest 3. A lateral tilting of the chair 1 is thus avoided despite its rotatability.
- a suitable design of the swivel head 15 and / or the base support 14 can also prevent an undesired swiveling movement in the opposite direction, that is to say forward here, for. B. by providing suitable stops on the swivel head 15 and / or base support 14.
- Forward and “rear” refers to the longitudinal direction 24 defined by the position of the seat 2, is therefore independent of a certain rotational position.
- the pivot axis 22 extends off-center on the pivot head 15, offset from the axis of rotation 16, so that the pivot axis 22 and axis of rotation 16 do not intersect. On the one hand, this enables a sufficient swivel angle 25 with the smallest installation space of the rotating and swiveling device 6. On the other hand, it prevents eccentric arrangement of the pivot axis 22 a too strong lifting of the part of the swivel head 15 viewed forward in the longitudinal direction 24 of the chair. Finally, the eccentric arrangement on the side of the receiving space opposite the swivel axis 22 between the swivel head 15 and the base support 14 creates sufficient space for a lock and a Spring element arrangement, as described in more detail below.
- the pivot axis 22 is preferably arranged at a distance from the axis of rotation 16 in the direction opposite to the pivoting movement 23 into the pivoting position.
- the rotating and pivoting device 6 comprises, as in the Fig. 5 and 6 illustrates a spring element arrangement for influencing the pivoting resistance of the rotatable and pivotable assembly 5.
- a number of spring elements 26 are provided between the pivot head 15 and the base support 14 on the side of the pivot mount 21 opposite the pivot axis 22.
- the spring element arrangement preferably has two spring elements 26 which act in parallel and act on the swivel head 15 and base carrier 14. These are used to adjust the swivel spring position.
- a particularly advantageous kinematic sequence can be achieved by using compression springs 26. All-round rubber elements or the like are not required. No involvement of the pedestal 9 is necessary to adjust the pivoting resistance in this way. All components are located within the combined rotating and swiveling device 6.
- the pivoting can be blocked in other embodiments.
- Lock position shown blocks the locking element 27 by a mechanical stop lowering the pivot head 15 and thus prevents pivoting of the entire assembly 5.
- This locking is preferably actuated from the outside, ie with the help of an (not shown) actuating element, which on the base bracket 14th or is provided on the swivel head 15.

Description
Die Erfindung betrifft eine Sitzvorrichtung.The invention relates to a seat device.
Übliche Sitzvorrichtungen umfassen das eigentliche Sitzelement, welches über ein Tragelement mit einem Standelement verbunden ist. Mit Hilfe des Standelements ist die Sitzvorrichtung auf einer entsprechenden Standfläche aufstellbar.Usual seat devices include the actual seat element, which is connected to a stand element via a support element. With the help of the stand element, the seat device can be set up on a corresponding stand surface.
Es ist bekannt, das Sitzelement drehbar auf dem Tragelement anzuordnen, so daß sich ein auf der Sitzvorrichtung sitzender Benutzer nach rechts oder links drehen kann. Es ist außerdem bekannt, ein Verschwenken des Sitzelements zu ermöglichen, insbesondere nach hinten, wenn das Sitzelement über eine Rückenlehne verfügt.It is known to arrange the seat element rotatably on the support element, so that a user sitting on the seat device can turn to the right or left. It is also known to enable the seat element to pivot, in particular to the rear, if the seat element has a backrest.
Die verschiedenen Bewegungen des Sitzelements werden üblicherweise mit Hilfe einer zwischen Sitzelement und Tragelement vorgesehenen Baugruppe realisiert, die als "Sitzmechanik" bezeichnet wird und zu diesem Zweck oftmals einen komplizierten konstruktiven Aufbau aufweist. Dies ist insbesondere bei Bürostühlen der Fall sowie bei anderen Sitzvorrichtungen mit ähnlichen funktionalen Eigenschaften.The various movements of the seat element are usually realized with the aid of an assembly provided between the seat element and the support element, which is referred to as the “seat mechanism” and for this purpose often has a complicated structural design. This is particularly the case with office chairs and with other seating devices with similar functional properties.
Eine Aufgabe der vorliegenden Erfindung ist es, eine Sitzvorrichtung bereitzustellen, bei der eine definierte Dreh- und Schwenkbewegung des Sitzelements ermöglicht wird, ohne daß zwischen Sitzelement und Tragelement eine Sitzmechanik-Funktionseinheit angeordnet sein muß.An object of the present invention is to provide a seat device in which a defined rotation and pivoting movement of the seat element is made possible without a seat mechanism functional unit having to be arranged between the seat element and the support element.
Diese Aufgabe wird durch eine Sitzvorrichtung nach Anspruch 1 gelöst.This object is achieved by a seat device according to claim 1.
Die erfindungsgemäße Sitzvorrichtung umfaßt eine kombinierten Dreh- und Schwenkvorrichtung zum Drehen und Schwenken einer Baugruppe der Sitzvorrichtung, wobei diese Baugruppe das Sitzelement des Sitzvorrichtung umfaßt, und wobei die Dreh- und Schwenkvorrichtung entfernt von dem Sitzelement der Sitzvorrichtung, nämlich nahe einer Standfläche der Sitzvorrichtung angeordnet ist. Dabei ist die Dreh- und Schwenkvorrichtung derart ausgeführt, daß ungeachtet der Drehstellung der Baugruppe eine Schwenkbewegung der Baugruppe stets nur in eine einzige Richtung bezogen auf diese Baugruppe möglich ist, mit einem auf der Standfläche aufstellbaren Standelement, mit einem mit dem Standelement verbundenen Tragelement und mit einem von dem Tragelement getragenen Sitzelement, wobei die Dreh- und Schwenkvorrichtung das Standelement mit dem Tragelement verbindet und das Tragelement und das Sitzelement Teile der dreh- und schwenkbaren Baugruppe sind, wobei die Dreh- und Schwenkvorrichtung einen Grundträger und einen mit dem Tragelement verbundenen Schwenkkopf aufweist, wobei der Grundträger an dem Standelement um eine Drehachse drehbar gelagert ist und wobei der Schwenkkopf mit dem Grundkörper mittels einer Schwenkachse verbunden ist, um welche Schwenkachse der Schwenkkopf gegenüber dem Grundkörper verschwenkbar ist, dadurch gekennzeichnet, daß die Dreh- und Schwenkvorrichtung wenigstens ein Federelement zur Beeinflussung des Schwenkwiderstandes der dreh- und schwenkbaren Baugruppe aufweist, welches wenigstens eine Federelement an Schwenkkopf und Grundträger angreift.The seating device according to the invention comprises a combined rotating and swiveling device for rotating and swiveling an assembly of the seating device, this assembly comprising the seat element of the seating device, and wherein the rotating and swiveling device is arranged remote from the seating element of the seating device, namely near a base of the seating device . The rotating and swiveling device is designed in such a way that, regardless of the rotational position of the assembly, a swiveling movement of the assembly is only possible in one direction with respect to this assembly, with a stand element that can be set up on the base, with a support element connected to the stand element and with a seat element carried by the support element, the rotating and pivoting device connecting the stand element to the supporting element and the supporting element and the seat element being parts of the rotatable and pivotable assembly, the rotating and pivoting device having a base support and a pivoting head connected to the supporting element , wherein the base support is rotatably mounted on the stand element about an axis of rotation and wherein the pivot head is connected to the base body by means of a pivot axis, about which pivot axis the pivot head can be pivoted relative to the base body, characterized in that the rotation and pivoting vo direction has at least one spring element for influencing the pivoting resistance of the rotatable and pivotable assembly, which engages at least one spring element on the pivoting head and base support.
Vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Eine erste Grundidee der Erfindung ist es, ein zum Drehen und Schwenken des Sitzelements dienende Dreh- und Schwenkvorrichtung entfernt von dem Sitzelement der Sitzvorrichtung anzuordnen, nämlich nahe einer Standfläche der Sitzvorrichtung. Eine zwischen Sitzelement und Tragelement angeordnete Sitzmechanik-Funktionseinheit zur Verwirklichung der Dreh- und Schwenkvorrichtung ist somit nicht mehr erforderlich.A first basic idea of the invention is to arrange a rotating and swiveling device for rotating and swiveling the seating element away from the seating element of the seating device, namely near a standing surface of the seating device. A seat mechanism functional unit arranged between the seat element and the support element for realizing the rotating and pivoting device is therefore no longer required.
Da die Dreh- und Schwenkvorrichtung somit an oder in dem Standelement oder jedenfalls in der Nähe des Standelements vorgesehen ist, befindet sie sich im unteren Bereich des Tragelements, vorzugsweise am unteren Ende des Tragelements. Das bedeutet, daß das Drehen und Schwenken nicht nur das Sitzelement selbst, sondern eine das Sitzelement umfassende Baugruppe betrifft, wobei diese Baugruppe vorzugsweise das Sitzelement sowie das Tragelement umfaßt. Mit anderen Worten wird bei einem Drehen und/oder Schwenken sowohl das Sitzelement als auch das Tragelement mitbewegt. Zu diesem Zweck ist das Tragelement vorzugsweise fest mit dem Sitzelement verbunden. Lediglich das Standelement verbleibt bewegungslos.Since the rotating and swiveling device is thus provided on or in the stand element or in any case in the vicinity of the stand element, it is located in the lower region of the support element, preferably at the lower end of the support element. This means that the turning and swiveling affects not only the seat element itself, but an assembly comprising the seat element, this assembly preferably being the seat element and includes the support member. In other words, when rotating and / or swiveling, both the seat element and the support element are also moved. For this purpose, the support element is preferably firmly connected to the seat element. Only the stand element remains motionless.
Bei der Sitzvorrichtung kann es sich um ein beliebiges Sitzmöbel handeln, insbesondere einen Stuhl. Die Sitzvorrichtung kann jedoch auch als Sessel, Hocker usw. ausgeführt sein.The seating device can be any piece of seating, in particular a chair. However, the seating device can also be designed as an armchair, stool, etc.
Bei dem Sitzelement kann es sich beispielsweise um einen mit einer Polsterung versehenen Sitzträger mit oder ohne Rückenlehne bzw. um eine Sitz- und Rückenlehne umfassende Sitzschale handeln. Aber auch jede beliebige andere Ausführung des Sitzelements ist denkbar. So kann, auch wenn dies für eine Verwirklichung der Dreh- und Schwenkbewegung nicht erforderlich ist, das Sitzelement dennoch eine Sitzmechanik-Funktionseinheit aufweisen, mit Hilfe der zusätzlich zu der erfindungsgemäß bereitgestellten Dreh- und Schwenkbewegung weitere Bewegungen des Sitzelements verwirklicht werden können.The seat element can, for example, be a seat support provided with upholstery with or without a backrest or a seat shell comprising a seat and backrest. But any other design of the seat element is also conceivable. Thus, even if this is not necessary for realizing the rotating and swiveling movement, the seat element can nevertheless have a seat mechanism functional unit, with the aid of the rotating and swiveling movement provided according to the invention, further movements of the seat element can be realized.
Bei dem Tragelement kann es sich beispielsweise um eine Standsäule handeln, die höhenverstellbar ausgeführt sein kann. Das Tragelement kann dabei mit dem Sitzelement einteilig verbunden sein. Anstelle einer Standsäule können jedoch auch anders geformte Tragelemente zum Einsatz kommen, beispielsweise V- oder U-förmige Tragelemente oder dergleichen, welche an mehreren voneinander beabstandeten Punkten mit dem Sitzelement verbunden sind. Vorzugsweise weist das Tragelement jedoch stets ein definiertes unteres Ende im Sinne eines unteren Endpunktes auf, das über die Dreh- und Schwenkvorrichtung mit dem Standelement verbunden ist.The support element can be, for example, a pedestal that can be made height-adjustable. The support element can be connected in one piece to the seat element. Instead of a stand column, however, differently shaped support elements can also be used, for example V-shaped or U-shaped support elements or the like, which are connected to the seat element at several spaced apart points. However, the support element preferably always has a defined lower end in the sense of a lower end point, which is connected to the stand element via the rotating and pivoting device.
Bei dem Standelement handelt es sich vorzugsweise um einen Standfuß. Dieser kann als runder oder eckiger Teller oder aber als Fußkreuz mit drei, vier, fünf Beinen usw. ausgeführt sein.The stand element is preferably a stand. This can be designed as a round or square plate or as a star base with three, four, five legs, etc.
Das Sitzelement ist zusammen mit dem Tragelement mit Hilfe der kombinierten Dreh- und Schwenkvorrichtung in dem feststehenden Standfuß drehbar gelagert, wobei die Drehachse vorzugsweise die Mittellängsachse des Tragelements ist bzw. die Drehachse in Längsrichtung des Tragelements verläuft.The seat element, together with the support element, is rotatably mounted in the fixed base with the aid of the combined rotating and pivoting device, the axis of rotation preferably being the central longitudinal axis of the support element or the axis of rotation extending in the longitudinal direction of the support element.
Eine zweite Grundidee der Erfindung ist es, die kombinierte Dreh- und Schwenkvorrichtung derart auszuführen, daß ein Verschwenken des Tragelements und damit der dreh- und schwenkbaren Baugruppe, einschließlich des Sitzelements, nur in eine einzige definierte Richtung möglich ist. Dadurch wird die gesamte Baugruppe oberhalb des Standfußes richtungsgenau verkippt. Zugleich ist eine Drehung des Tragelements möglich, ohne daß sich dabei die zulässige Schwenkrichtung ändert. Mit anderen Worten ist die Schwenkrichtung relativ zu dem Sitzelement feststehend. Unabhängig davon, wie weit sich ein Benutzer der Sitzvorrichtung nach rechts oder links gedreht hat, ist daher ein Verschwenken immer nur nach hinten möglich, also z.B. in Richtung der Rückenlehne. Ein unbeabsichtigtes Kippen des Sitzelements nach rechts oder links, wie es im verdrehten Zustand sonst befürchtet werden müßte, wird dadurch sicher vermieden.A second basic idea of the invention is to design the combined rotating and pivoting device in such a way that pivoting of the support element and thus of the rotatable and pivotable assembly, including the seat element, is only possible in a single defined direction. As a result, the entire assembly is tilted in the correct direction above the base. At the same time, a rotation of the support element is possible without changing the permissible pivoting direction. In other words, the pivoting direction is fixed relative to the seat element. Regardless of how far a user of the seat device has turned to the right or left, pivoting is therefore only possible to the rear, e.g. towards the backrest. An unintentional tilting of the seat element to the right or left, as would otherwise be feared in the twisted state, is thereby reliably avoided.

Ein Stuhl 1 mit einem gepolsterten Sitz 2 und einer gepolsterten Rückenlehne 3 ist in
Anstelle der Stuhlsäule 4 kann auch ein anders geformtes Tragelement verwendet werden, beispielsweise ein V-förmiges oder U-förmige Tragelement, wie in
Der Standfuß 9 weist, wie in
Die Dreh- und Schwenkvorrichtung 6 umfaßt einen Grundträger 14 und einen an dem unteren Ende 8 der Stuhlsäule 4 angeordneten Schwenkkopf 15, siehe
Der Grundträger 14 seinerseits weist mittig eine Schwenkaufnahme 21 auf zur Aufnahme des Schwenkkopfes 15. Der Schwenkkopf 15 ist dabei entweder, wie im skizzierten Fall, einteilig mit der Stuhlsäule 4 verbunden oder aber der Schwenkkopf 15 weist eine entsprechende Konusaufnahme für die Stuhlsäule 4 auf (nicht abgebildet).The
Der Schwenkkopf 15 ist über eine horizontale Schwenkachse 22 gelenkig mit dem Grundträger 14 verbunden, siehe
Die Schwenkachse 14 dient zugleich als Verbindungselement dieser beiden Hauptkomponenten der Dreh- und Schwenkvorrichtung 6. Dadurch ist garantiert, daß sich Grundträger 14 und Schwenkkopf 15 stets miteinander und gemeinsam drehen. So gewährleistet die als Verbindungsachse dienende Schwenkachse 22, daß sich stets die gesamte Dreh- und Schwenkvorrichtung 6 dreht. Der Schwenkkopf 15 läßt sich in der Schwenkaufnahme 21 des Grundträgers 14 aus einer nichtverschwenkten Grundstellung, wie in
Der Schwenkkopf 15 ist um diese Schwenkachse 22 in eine einzige definierte Schwenkrichtung 23 relativ zu dem nichtverschwenkbaren Grundkörper 14 verschwenkbar. Die Schwenkrichtung 23 des Schwenkkopfes 15 und damit die Schwenkrichtung 23 der gesamten Baugruppe 5 beziehen sich somit immer auf den Grundträger 14. Die Schwenkbewegung erfolgt stets in eine einzige definierte Richtung 23, radial in Bezug auf die Stuhlsäule 4, relativ zu dem Sitz 2. Erfindungsgemäß erfolgt somit die Schwenkbewegung unabhängig von dem aktuellen Drehwinkel stets in die gewünschte Richtung 23, vorzugsweise nach hinten, d. h. in Richtung der Rückenlehne 3. Ein seitliches Kippen des Stuhles 1 wird somit trotz seiner Drehbarkeit vermieden.The
Durch eine geeignete Ausgestaltung des Schwenkkopfes 15 und/oder des Grundträgers 14 kann zudem eine unerwünschte Schwenkbewegung in die entgegengesetzte Richtung, hier also nach vorn, verhindert werden, z. B. durch die Bereitstellung geeigneter Anschläge an Schwenkkopf 15 und/oder Grundträger 14. "Vorn" und "hinten" bezieht sich dabei auf die durch die Stellung des Sitzes 2 definierte Stuhllängsrichtung 24, ist daher unabhängig von einer bestimmten Drehstellung.A suitable design of the
Die Schwenkachse 22 verläuft am Schwenkkopf 15 außermittig, versetzt zu der Drehachse 16, so daß sich Schwenkachse 22 und Drehachse 16 nicht schneiden. Hierdurch wird einerseits ein ausreichender Schwenkwinkel 25 bei kleinstem Bauraum der Dreh- und Schwenkvorrichtung 6 ermöglicht. Andererseits verhindert die außermittige Anordnung der Schwenkachse 22 ein zu starkes Anheben des in Stuhllängsrichtung 24 gesehen nach vorn gerichteten Teils des Schwenkkopfes 15. Schließlich schafft die exzentrische Anordnung auf der der Schwenkachse 22 gegenüber liegenden Seite des Aufnahmeraumes zwischen Schwenkkopf 15 und Grundträger 14 ausreichend Platz für eine Verriegelung und ein Federelementanordnung, wie nachfolgend näher beschrieben.
