Description

S u l S u l
Die Erfindung betrifft einen Stuhl mit zumindest einem Fuss und einem Trägerprofil, an dem ein Sitz und gegebenenfalls eine Rückenlehne angeordnet ist, wobei der Sitz an dem Trägerprofil in der Höhe stufenlos verstellbar ist.The invention relates to a chair with at least one foot and a support profile, on which a seat and optionally a backrest is arranged, the height of the seat on the support profile being infinitely adjustable.
Stühle gibt es in vielfältigster Ausführung und Form. Die vorliegende Erfindung bezieht sich speziell auf einen Stuhl, dessen Sitz in der Höhe und/oder dessen Sitztiefe einstellbar ist. Ferner bezieht sich die Erfindung auf einen Stuhl, der zusammenlegbar ist.Chairs come in a wide variety of designs and shapes. The present invention relates specifically to a chair whose height and / or seat depth is adjustable. Furthermore, the invention relates to a chair that is collapsible.
Aus der US-A-4 148 523 ist beispielsweise ein Stuhl bekannt, dessen Sitz entlang einem Trägerprofil in der Höhe verstellbar ist. Zum Verstellen wird der Sitz angehoben, ein Verbindungselement entlang dem Trägerprofil verschoben und dann der Sitz wieder abgesenkt, wobei er eine Klemmwirkung auf das Trägerprofil ausübt.For example, a chair is known from US-A-4 148 523, the seat of which is adjustable in height along a support profile. To adjust the seat is raised, a connecting element is moved along the support profile and then the seat is lowered again, exerting a clamping effect on the carrier profile.
Dieser Stuhl hat den Nachteil, dass, wenn beispielsweise der Sitz versehentlich angehoben wird, die Höhe leicht von sich aus verstellt wird. Die Klemmwirkung des Sitzes gegenüber dem Trägerprofil hängt im wesentlichen von dem Druck ab, der auf den Sitz ausgeübt wird.The disadvantage of this chair is that if, for example, the seat is accidentally raised, the height can easily be adjusted by itself. The clamping effect of the seat against the support profile essentially depends on the pressure that is exerted on the seat.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Stuhl der oben genannten Art zu entwickeln, der sowohl in seiner Einstellung als auch in seiner Handhabung sehr variabel ist.The present invention has for its object to develop a chair of the type mentioned above, which is very variable both in its setting and in its handling.
Zur Lösung dieser Aufgabe führt, dass der Sitz in einer gewünschten Höhe mit einer Höhensicherung gesichert festlegbar ist.The solution to this problem is that the seat can be secured at a desired height with a height safety device.
Die Höhensicherung ist ein wichtiges Element der vorliegenden Erfindung, da durch sie vermieden wird, dass eine gewünschte eingestellte Höhe für den Sitz unabsichtlich verändert wird.The height safety device is an important element of the present invention, since it avoids that a desired set height for the seat is inadvertently changed.
Der Einbau der Höhensicherung kann erfolgen zwischen Trägerprofil und Sitzträger bzw. Sitz oder umgekehrt. Er kann aber auch erfolgen zwischen Sitzträger und einem Verbindungselement oder umgekehrt. Ebenso ist es möglich, dass die Höhensicherung zwischen Trägerprofil und Verbindungselement oder umgekehrt vorgesehen wird.The height safety device can be installed between the support profile and the seat support or seat or vice versa. But it can also take place between the seat support and a connecting element or vice versa. It is also possible that the leveling device is provided between the support profile and the connecting element or vice versa.
Sollte eine Rückenlehnen-Trägerprofilverbindung gesondert vorgesehen sein, so kann die Höhensicherung zwischen dieser Profilverbindung und dem Sitzträger oder umgekehrt, zwischen dieser Profilverbindung und einem Verbindungselement oder umgekehrt, zwischen dieser Profilverbindung und dem Trägerprofil oder umgekehrt oder aber zwischen Zwischen- und Verbindungselement vorgesehen werden, welche bei der Höhenverstellung mitgeführt und mit den verschiedenen Komponenten wie Trägerprofil, 5 Rückenlehne, Trägerprofilverbindung, Verbindungselement oder Sitzträger verbunden und somit ein Teil von diesen sind.If a backrest-support profile connection is provided separately, the height protection between this profile connection and the seat support or vice versa, between this profile connection and a connecting element or vice versa, between the latter Profile connection and the support profile or vice versa or between the intermediate and connecting element are provided, which are carried with the height adjustment and connected to the various components such as support profile, 5 backrest, support profile connection, connecting element or seat support and are therefore part of these.
Als Höhensicherung sollen alle möglichen bekannten L0 Einrastmechanismen, Bewegungsblocker usw. in Frage kommen, wie z.b. Druckknöpfe, Verschlüsse, Schnapper usw.. In einem bevorzugten Ausführungsbeispiel weist die Höhensicherung zumindest ein Klemmelement auf, welches so in einer Kulisse geführt ist, dass es, sobald der Sitz bzw. Sitzträger seine L5 gewünschte Höhe erreicht hat, eine Klemmwirkung ausübt, die vermeidet, dass der Sitz ohne Lösen des Klemmelementes aus seiner Lage gebracht wird.All possible known L0 snap-in mechanisms, movement blockers, etc. should be used as a height safety device, e.g. Push buttons, closures, snappers, etc. In a preferred exemplary embodiment, the height safety device has at least one clamping element which is guided in a setting in such a way that, as soon as the seat or seat support has reached its desired height, it avoids a clamping effect that the seat is moved out of its position without loosening the clamping element.
In einem weiteren Ausführungsbeispiel ist daran gedacht, 20 sogar zwei Klemmelemente vorzusehen, wobei das zweite Klemmelement verhindert, dass der Sitz angehoben wird.In a further exemplary embodiment it is contemplated to even provide two clamping elements, the second clamping element preventing the seat from being raised.
In einem anderen Ausführungsbeispiel der Erfindung besteht die Höhensicherung im wesentlichen aus einer Stellklinke, 5 welche eine Rastkante aufweist, die in Sicherungslage von einer entsprechenden Kante am Sitzträger hintergriffen wird. Hierdurch wird ein am Sitzträger vorhandener Belag gegen das Trägerprofil gepresst, wodurch die Lage des Sitzträgers gesichert ist. 0In another embodiment of the invention, the height safety device essentially consists of an adjusting pawl 5 which has a latching edge which is engaged behind by a corresponding edge on the seat support in the secured position. As a result, an existing covering on the seat support is pressed against the support profile, thereby securing the position of the seat support. 0
Hier sind jedoch noch viele Möglichkeiten denkbar und sollen von der vorliegenden Erfindung umfasst sein.However, many possibilities are still conceivable here and are intended to be encompassed by the present invention.
Ein weiteres Merkmal der Erfindung, für das auch 5 selbständiger Schutz begehrt wird, bezieht sich auf die gelenkige Festlegung des Trägerprofils an zumindest einem Fuss. Das bedeutet, dass ein zusammenlegbarer Stuhl entsteht. Zu diesem Zweck kann beispielsweise am Fuss eine Lagerlasche festgelegt sein, welche mit dem Trägerprofil eine gelenkige Verbindung über einen Gelenkbolzen eingeht. Gleichzeitig bildet die Lagerlasche auch einen Anschlag für das Trägerprofil aus, sobald dieses in Gebrauchslage ist.Another feature of the invention, for which 5 independent protection is also sought, relates to the articulated fixing of the carrier profile on at least one foot. This means that a collapsible chair is created. For this purpose, a mounting bracket can be fixed to the foot, for example, which forms an articulated connection with the support profile via a hinge pin. At the same time, the bearing bracket also forms a stop for the carrier profile as soon as it is in the position of use.
Die Gebrauchslage wird durch eine Rastklinke gesichert, welche mit einer Rastnase in das Trägerprofil eingreift. Dies geschieht unter dem Druck einer Feder, so dass erst bei Aufheben dieses Druckes ein Lösen der Rastklinke und damit ein Freigeben des Trägerprofils erfolgt.The position of use is secured by a locking pawl which engages with a locking lug in the carrier profile. This takes place under the pressure of a spring, so that the detent pawl is only released and thus the carrier profile is released when this pressure is released.
Noch ein weiterer Gedanke der vorliegenden Erfindung, für den ebenfalls selbständig Schutz begehrt wird, bezieht sich auf die Verstellbarkeit der Sitztiefe. Grundsätzlich ist daran gedacht, die Sitztiefe verstellbar auszugestalten. Dies kann einmal dadurch geschehen, dass eine entsprechende, beispielsweise textile Sitzfläche aufgerollt ist und je nach Wunsch von beispielsweise einer Rolle abgerollt werden kann.Yet another idea of the present invention, for which protection is also sought independently, relates to the adjustability of the seat depth. The basic idea is to make the seat depth adjustable. On the one hand, this can be done by rolling up a corresponding, for example textile, seat surface and, if desired, unrolling it from a roll, for example.
Vorzugsweise geschieht das Erhöhen bzw. Verringern der Sitztiefe unter Einwirkung eines Teleskopelementes. Beispielsweise könnte dies ein Rechenauszug, zumindest ein Kniehebel oder ein Scherenelement sein.Preferably, the seat depth is increased or decreased under the action of a telescopic element. For example, this could be a rake extract, at least a toggle lever or a scissor element.
In einem anderen Ausführungsbeispiel ist daran gedacht, die Sitzfläche aus mehreren Teilen zu bilden, wobei je nach Wunsch die Teile auseinander gezogen und durch neue Teile ergänzt werden. Auch hier soll der vorliegenden Erfindung keine Grenze gesetzt sein. Ein besonderer Erfindungsgedanke, für den ebenfalls auch separat Schutz begehrt wird, bezieht sich auf die Anordnung einer zusätzlichen Rückenlehne, durch deren Verstellung ebenfalls die Sitztiefe verändert werden kann.In another embodiment, it is contemplated to form the seat surface from several parts, the parts being pulled apart as required and supplemented by new parts. Here, too, there should be no limit to the present invention. A particular idea of the invention, for which protection is also sought separately, relates to the arrangement of an additional backrest, the adjustment of which can also be used to change the seat depth.
Selbstverständlich ist daran gedacht, alle selbständigen Merkmale auch in einem Stuhl zu verwirklichen, für den ebenfalls Schutz begehrt wird. Hierdurch wird ein Stuhl hergestellt, der ausserordentlich variabel bezüglich seiner Einstellungen ist. Ferner kann er leicht zusammengelegt und transportiert werden. It goes without saying that all independent features are also implemented in a chair for which protection is also sought. This creates a chair that is extremely variable in its settings. It can also be easily folded and transported.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt inFurther advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
Figur 1 eine perspektivische Ansicht eines erfindungsgemässen Stuhls;Figure 1 is a perspective view of a chair according to the invention;
Figur 2 eine Seitenansicht eines Ausschnitts aus dem Stuhl gemäss Figur 1 im Bereich der Verbindung zwischen Trägerprofil und Fuss;FIG. 2 shows a side view of a detail from the chair according to FIG. 1 in the area of the connection between the support profile and the foot;

Figur 6 ein weiteres Ausführungsbeispiel eines Ausschnittes aus dem Stuhl gemäss Figur 1 ähnlich den Figuren 4 und 5 in unterschiedlichen Gebrauchslagen;Figure 6 shows another embodiment of a section of the chair according to Figure 1 similar to Figures 4 and 5 in different positions of use;
Figur 7 einen Ausschnitt aus einem weiteren Ausführungsbeispiel des Stuhl gemäss Figur 1 ähnlich Figur 6;FIG. 7 shows a detail from a further exemplary embodiment of the chair according to FIG. 1, similar to FIG. 6;
Figuren 8 - 13 perspektivische Ansichten von Ausführungsbeispielen von Sitzflächen, deren Tiefe veränderbar ist; Figur 14 perspektivische Ansichten von Möglichkeiten einer Rückenlehnenverstellung.FIGS. 8-13 are perspective views of exemplary embodiments of seating surfaces whose depth can be changed; Figure 14 perspective views of options for a backrest adjustment.
Gemäss Figur 1 weist ein erfindungsgemässer Stuhl P zwei Füsse 1.1 und 1.2 auf, welche jeweils mit einem Trägerprofil 2.1 und 2.2 verbunden sind. Die Trägerprofile 2.1 und 2.2 nehmen zwischen sich eine Rückenlehne 3 auf.According to FIG. 1, a chair P according to the invention has two feet 1.1 and 1.2, which are each connected to a support profile 2.1 and 2.2. The carrier profiles 2.1 and 2.2 accommodate a backrest 3 between them.
Über jeweils ein Verbindungselement 4.1 bzw.4.2 ist ein Sitz 5 mit den Trägerprofilen 2.1 und 2.2 verbunden. Diese Verbindung geschieht gegebenenfalls über entsprechende Sitzträger 6.A seat 5 is connected to the carrier profiles 2.1 and 2.2 via a connecting element 4.1 or 4.2, respectively. This connection takes place, if necessary, via corresponding seat supports 6.
In den Figuren 2 und 3 ist erkennbar, dass ein Trägerprofil 2 über eine Gelenkverbindung 7 mit einem Fuss 1 verbunden ist. Dabei weist die Gelenkverbindung 7 bevorzugt zwei hintereinander angeordnete Lagerlaschen 8 auf, wobei die Lagerlaschen 8 über einen Gelenkbolzen 9 mit dem Trägerprofil 2 verbunden sind. Das Trägerprofil 2 kann um den Gelenkbolzen 9 drehen.It can be seen in FIGS. 2 and 3 that a carrier profile 2 is connected to a foot 1 via an articulated connection 7. The articulated connection 7 preferably has two bearing brackets 8 arranged one behind the other, the bearing brackets 8 being connected to the carrier profile 2 via a joint bolt 9. The carrier profile 2 can rotate about the hinge pin 9.
Die Drehbewegung des Trägerprofils 2 gegenüber der Lagerlasche 8 wird allerdings durch eine Abkantung 10 begrenzt, welche einen Anschlag für das Trägerprofil 2 ausbildet.The rotational movement of the carrier profile 2 with respect to the bearing bracket 8 is, however, limited by a bevel 10, which forms a stop for the carrier profile 2.
Zwischen den beiden Lagerlaschen 8 ist eine Rastklinke 11 vorgesehen, welche in Gebrauchslage gemäss Figur 2 mit einer Rastnase 12 in das Trägerprofil 2 eingreift und dieses in der Gebrauchslage festlegt.Between the two mounting brackets 8 there is a latching pawl 11 which, in the position of use according to FIG. 2, engages with a latching lug 12 in the carrier profile 2 and fixes it in the position of use.
Die Rastnase 12 kann ausser Eingriff mit dem Trägerprofil 2 gebracht werden, indem auf einen Hebel 13 gedrückt wird und dadurch die Rastklinke 11 gegen den Druck einer Feder 14 ausser Rastlage gebracht wird, wie dies in Figur 3 gezeigt ist. Dabei dreht die Rastklinke 11 um eine Achse 15.The locking lug 12 can be brought out of engagement with the carrier profile 2 by pressing on a lever 13 and thereby the locking pawl 11 against the pressure of a spring 14 is brought out of rest position, as shown in Figure 3. The pawl 11 rotates about an axis 15.
Zum Einrasten wird das Trägerprofil 2 um den Gelenkbolzen 9 geschwenkt, wobei eine Steuerkante 16 auf die Rastklinke 11 aufgleitet und die Rastnase 12 überfährt, bis die Rastnase unter dem Druck der Feder 14 in das Trägerprofil 2 einfährt.For latching, the carrier profile 2 is pivoted about the hinge pin 9, a control edge 16 sliding onto the latching pawl 11 and driving over the latching lug 12 until the latching lug enters the carrier profile 2 under the pressure of the spring 14.
Gemäss den Figuren 4 - 7 sollen der Sitz 5 bzw. seine Sitzträger 6 entlang dem Trägerprofil 2 verschiebbar und in einer gewünschten Höhe festlegbar sein. Hierzu ist dem Verbindungselement 4 eine Höhensicherung 17 zugeordnet. Diese Höhensicherung 17 besitzt eine Stellklinke 18, welche schwenkbar um eine Schwenkachse 19 in dem Verbindungselement 4 gelagert ist.According to FIGS. 4-7, the seat 5 or its seat support 6 should be displaceable along the support profile 2 and be fixable at a desired height. For this purpose, a height safety device 17 is assigned to the connecting element 4. This height safety device 17 has a pawl 18 which is pivotally mounted about a pivot axis 19 in the connecting element 4.
Die Stellklinke 18 weist eine Rastkante 20 auf, die mit einer Kante 21 am Sitzträger 6 zusammenwirkt.The pawl 18 has a locking edge 20 which cooperates with an edge 21 on the seat support 6.
Der Sitzträger 6 ist um eine weitere Schwenkachse 22 schwenkbar an dem Verbindungselement 4 angeordnet. Die Schwenkachse 22 ist dabei so angeordnet, dass ein dem Sitzträger 6 zugeordneter Belag 23 in Sitzposition des Sitzträgers 6 (Figur 5) flächig auf dem Trägerprofil 2 anliegt, wobei gleichzeitig die Kante 21 die Rastkante 20 der Stellklinke 18 überfahren hat und die Stellklinke 18 unter dem Druck einer Feder 24 die Kante 21 übergriffen hat. Hierdurch wird zum einen der Belag 23 auf die Oberfläche des Trägerprofils 2 aufgedrückt und zum anderen durch die Stellklinke 18 in dieser Drucklage gehalten, so dass ein Verschieben des Verbindungselementes 4 entlang dem Trägerprofil 2 erst nach Lösen der Stellklinke 18 möglich ist. In den Figuren 6a bis 6c ist ein weiteres Ausführungsbeispiel einer Höhensicherung 17.1 gezeigt. Diese Höhensicherung 17.1 weist einen Schwenkhebel 25 auf, der drehbar um eine Drehachse 26 mit dem Verbindungselement 4 gekoppelt ist. Mit diesem Schwenkhebel 25 kann eine Klemmrolle 27 in einer Kulisse 28 bewegt werden. Die Kulisse 28 ist als gekrümmtes Langloch ausgebildet, in dessen lichte Weite das Trägerprofil 2 etwas einragt.The seat support 6 is arranged on the connecting element 4 so as to be pivotable about a further pivot axis 22. The pivot axis 22 is arranged in such a way that a covering 23 assigned to the seat support 6 lies flat on the support profile 2 in the seating position of the seat support 6 (FIG. 5), the edge 21 simultaneously passing over the latching edge 20 of the adjusting pawl 18 and the adjusting pawl 18 underneath the pressure of a spring 24 has overlapped the edge 21. In this way, on the one hand, the covering 23 is pressed onto the surface of the carrier profile 2 and, on the other hand, it is held in this pressure position by the adjusting pawl 18, so that a displacement of the connecting element 4 along the carrier profile 2 is only possible after the adjusting pawl 18 has been released. A further exemplary embodiment of a height safety device 17.1 is shown in FIGS. 6a to 6c. This height safety device 17.1 has a swivel lever 25 which is rotatably coupled to the connecting element 4 about an axis of rotation 26. With this pivot lever 25, a pinch roller 27 can be moved in a link 28. The backdrop 28 is designed as a curved elongated hole, in the clear width of which the support profile 2 protrudes somewhat.
Bei gelöster Klemmrolle 27 gemäss Figur 6a kann das Verbindungselement 4 entlang dem Trägerprofil 2 bewegt werden. Ist die gewünschte Höhe für den Sitz erreicht, wird der Schwenkhebel 25 um die Drehachse 26 gedreht, so dass die Klemmrolle 27 in den Bereich des Trägerprofils 2 gelangt. Hierdurch wird zwischen Kulisse 28, Klemmrolle 27 und Trägerprofil 2 eine Klemmwirkung erzielt, wie dies in Figur 6b angedeutet ist.With the pinch roller 27 released according to FIG. 6a, the connecting element 4 can be moved along the carrier profile 2. When the desired height for the seat has been reached, the swivel lever 25 is rotated about the axis of rotation 26, so that the pinch roller 27 reaches the area of the carrier profile 2. As a result, a clamping effect is achieved between the link 28, the clamping roller 27 and the carrier profile 2, as is indicated in FIG. 6b.
Wird jetzt der Sitzträger 6 um seine Schwenkachse 22, wie in Figur 6c gezeigt, geschwenkt, so trifft der Belag 23 auf das Trägerprofil 2 auf, wobei, wenn dies gewünscht, der Belag 23 gegenüber der Oberfläche des Trägerprofils 2 noch so angestellt werden kann, dass das Verbindungselement 4 geringfügig nach unten versetzt wird. Hierdurch wird die Klemmrolle 27 noch weiter in den Klemmbereich zwischen Kulisse 28 und Oberfläche des Trägerprofils 2 eingezogen, so dass eine gesicherte Festlegung erfolgt.If the seat support 6 is now pivoted about its pivot axis 22, as shown in FIG. 6c, the covering 23 strikes the support profile 2, wherein, if so desired, the covering 23 can still be positioned relative to the surface of the support profile 2, that the connecting element 4 is displaced slightly downwards. As a result, the pinch roller 27 is drawn even further into the pinching area between the link 28 and the surface of the carrier profile 2, so that a secure fixing takes place.
Gemäss dem Ausführungsbeispiel nach Figur 7 sollen an dem Verbindungselement 4 zwei Schwenkhebel 25 und 25.1 vorgesehen werden. Beiden ist eine Kulisse 28 und 28.1 sowie eine Klemmrolle 27 und 27.1 zugeordnet. Die Klemmrolle 27.1 hat hier die Aufgabe, ein Verschieben des Verbindungselementes 4 in entgegengesetzte Richtung, d.h. am Trägerprofil 2 nach oben zu verhindern. Bei diesem Ausführungsbeispiel wird somit ein Verschieben des Verbindungselementes sowohl nach unten als auch nach oben vermieden.According to the exemplary embodiment according to FIG. 7, two pivot levers 25 and 25.1 are to be provided on the connecting element 4. Both are assigned a backdrop 28 and 28.1 and a pinch roller 27 and 27.1. The pinch roller 27.1 has the task here of preventing the connecting element 4 from moving in the opposite direction, ie upwards on the carrier profile 2. With this Embodiment is thus avoided moving the connecting element both downwards and upwards.
Ein weiterer Teil der vorliegenden Erfindung bezieht sich auf die Möglichkeit der Sitztiefenverstellung. In den Figuren 8 - 13 sind schematisch Möglichkeiten angedeutet, wie eine Sitztiefe verstellt werden kann.Another part of the present invention relates to the possibility of seat depth adjustment. FIGS. 8 through 13 schematically indicate possibilities of how a seat depth can be adjusted.
Gemäss Figur 8 umfängt eine Sitzfläche 30 eine Rolle 31, wobei beispielsweise die Sitzfläche 30 aus textilem Werkstoff bestehen kann. Wird an der Sitzfläche 30 beispielsweise gegen die Kraft eines Zugelementes gezogen, so wird ein bisher sich im Sitz befindender Teil der Sitzfläche herausgezogen und kann als Sitzfläche dienen.According to FIG. 8, a seat 30 surrounds a roller 31, it being possible for the seat 30 to be made of textile material, for example. If, for example, the seat surface 30 is pulled against the force of a tension element, a part of the seat surface that was previously in the seat is pulled out and can serve as a seat surface.
Gemäss Figur 9 könnte die Sitzfläche 30 auch einends auf eine Rolle 31.1 aufgewickelt sein, wobei diese Rolle unter einer Vorspannung stehen könnte, wodurch die Sitzfläche 30 gestreckt gehalten wird.According to FIG. 9, the seat surface 30 could also be wound at one end onto a roller 31.1, this roller being able to be under a prestress, as a result of which the seat surface 30 is kept stretched.
Gemäss Figur 10 könnte eine nicht näher gezeigte Sitzfläche 30, beispielsweise nach dem Ausführungsbeispiel gemäss Figur 9, von einem Rechenauszug 32 unterfangen sein. Der Rechenauszug 32 ist so ausgestaltet, dass einzelne Rechen gegenüber anderen Rechen teleskopartig verfahren werden können .According to FIG. 10, a seat surface 30, not shown in more detail, for example according to the exemplary embodiment according to FIG. 9, could be underpinned by a computing pull-out 32. The rake extract 32 is designed such that individual rakes can be moved telescopically compared to other rakes.
Gemäss Figur 11 und 12 wird ein ähnliches Ausfahren der Sitzfläche 30 mittels Kniehebel 33 bzw. Scheren 34 erreicht.According to FIGS. 11 and 12, a similar extension of the seat surface 30 is achieved by means of the toggle lever 33 or scissors 34.
In einem einfachen Ausführungsbeispiel der Erfindung gemäss Figur 13 genügt es, wenn die Sitzfläche aus mehreren Sitzflächenelementen 35.1 bis 35.2 besteht, die miteinander verbunden sein können.In a simple exemplary embodiment of the invention according to FIG. 13, it is sufficient if the seat surface consists of several Seat surface elements 35.1 to 35.2 exist which can be connected to one another.
Gemäss Figur 14 sind des weiteren Stühle dargestellt, bei denen zu einer normalen Rückenlehne 3 eine weitere Rückenlehne 36 angeordnet ist. Diese zusätzliche Rückenlehne 36 ist entlang dem Sitz 5 verstellbar, so dass eine Sitztiefe einer Person angepasst werden kann. Dies kann entweder dadurch erfolgen, dass die Rückenlehne 36 in an verschiedenen Positionen angeordneten Aufnahmen 37 gesteckt wird. Gedacht ist aber auch an eine stufenlose Verstellung, wobei in den Sitz eine entsprechende langlochartige Ausnehmung 38 eingeformt ist. Ein entsprechender Mechanismus zur Verstellung der Rückenlehne 36 ist hier nicht näher gezeigt. According to FIG. 14, chairs are also shown in which a backrest 36 is arranged in addition to a normal backrest 3. This additional backrest 36 is adjustable along the seat 5, so that a seat depth can be adapted to a person. This can be done either by inserting the backrest 36 into receptacles 37 arranged in different positions. However, it is also contemplated for a continuous adjustment, a corresponding slot-like recess 38 being formed in the seat. A corresponding mechanism for adjusting the backrest 36 is not shown in detail here.
