Abstract

A height-adjustable office chair having an incline-adjustable seat and back includes a bearing device to which is connected a length-adjustable seat pneumatic spring connected by an articulated joint to the seat structure, a length-adjustable back-rest pneumatic spring connected to the back by an articulated joint, and a height-adjustable pneumatic spring. The actuating rods of all three of these pneumatic springs are in the bearing device and are controlled by an actuating lever movable both horizontally and vertically. Vertical movement of the actuating lever controls the height-adjustable pneumatic spring. Horizontal movement of the actuating lever serves to control one of two intermediate levers which are respectively arrestable and lockable by a detent lever located above the height-adjustable pneumatic spring.

Description

Die Erfindung betrifft eine Trageinrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a carrying device according to the preamble of claim 1.

Bei einer derartigen aus der DE-OS 29 29 428 (entsprechend EP-PS o o22 933) bekannten Trageinrichtung ist als Führungsbahn eine Kulisse mit verschiedenen Führungsbahnen vorgesehen, in denen eine Zwangsführung und eine Festlegung des Betätigungshebels in einer ausgelenkten Stellung möglich ist. So kann der Betätigungshebel horizontal in einer Führungsbahn in der einen oder anderen Richtung verschwenkt werden, wodurch jeweils ein Betätigungsstift einer Gasfeder in diese eingeschoben wird. Hierdurch kann also jeweils gesondert eine Veränderung der Neigung des Sitzes bzw. der Rückenlehne durchgeführt werden. Um den Sitz und die Rückenlehne frei wippbar zu machen, um also die Arretierung durch die entsprechende Gasfeder aufzuheben, kann der Betätigungshebel in einer vertikalen Führungsbahn der Kulisse nach oben geschwenkt und elastisch eingerastet werden. In dieser Stellung schieben die entsprechenden Abschnitte eines am Betätigungshebel ausgebildeten und an den Zwischenhebeln anliegenden Ringes die beiden Zwischenhebel scherenartig auseinander, wodurch beide Betätigungsstifte in die jeweilige Gasfeder eingeschoben werden. Da der Betätigungshebel in dieser Stellung eingerastet wird, bleiben die Betätigungsstifte geöffnet, so daß Sitz und Rückenlehne frei - gegen den jeweiligen Gasdruck in der Gasfeder - wippen können. Da der am Betätigungshebel ausgebildete Ring die Stuhlsäule umgibt, kann die die Stuhlsäule bildende Gasfeder nicht mittels dieses Betätigungshebels verstellt werden. Bei einer praktischen Ausführung ist hierfür ein gesonderter Betätigungshebel vorgesehen. Weiterhin ist es nicht möglich, wahlweise nur bei der Rückenlehnengasfeder oder bei der Sitzgasfeder den Betätigungsstift in der eingeschobenen Stellung zu arretieren.In such a support device known from DE-OS 29 29 428 (corresponding to EP-PS o o22 933), a guide with various guideways is provided as the guideway, in which a positive guidance and a fixing of the actuating lever in a deflected position is possible. Thus, the actuating lever can be pivoted horizontally in one guideway in one direction or the other, whereby an actuating pin of a gas spring is inserted into each of these. In this way, a change in the inclination of the seat or the backrest can be carried out separately. In order to make the seat and the backrest freely rockable, so to release the lock by the corresponding gas spring, the actuating lever can move upwards in a vertical track of the link swivels and snaps into place. In this position, the corresponding sections of a ring formed on the actuating lever and abutting the intermediate levers push the two intermediate levers apart like a scissors, as a result of which both actuating pins are pushed into the respective gas spring. Since the operating lever is locked in this position, the operating pins remain open so that the seat and backrest can rock freely - against the gas pressure in the gas spring. Since the ring formed on the operating lever surrounds the chair column, the gas spring forming the chair column cannot be adjusted by means of this operating lever. In a practical version, a separate actuating lever is provided for this. Furthermore, it is not possible to lock the actuating pin in the inserted position only with the backrest gas spring or with the seat gas spring.

Aus der US-PS 3 837 7o4 ist es bei einem Stuhl mit einer durch eine längenverstellbare Gasfeder gebildeten Stuhlsäule und einer ebenfalls mittels einer Rückenlehnengasfeder neigungsverstellbaren Rückenlehne bekannt, mittels nur eines vertikal und horizontal verschwenkbaren Bedienungshebels wahlweise die Längenverstellung der Stuhlsäule oder die Längenverstellung der Rückenlehnengasfeder und damit die Neigungsverstellung der Rückenlehne auszulösen. Der Sitz ist hierbei nicht in seiner Neigung verstellbar. Eine Arretierung des Betätigungsstiftes in seiner eingeschobenen Stellung ist nicht vorgesehen.From US-PS 3 837 7o4 it is known in a chair with a chair column formed by a length-adjustable gas spring and a backrest which is also inclinable by means of a backrest gas spring, by means of only one vertically and horizontally pivotable operating lever either the length adjustment of the chair column or the length adjustment of the backrest gas spring and thus triggering the inclination adjustment of the backrest. The inclination of the seat is not adjustable. A locking of the actuating pin in its inserted position is not provided.

Eine ähnliche Lösung ist aus der CH-PS 563 753 bekannt.A similar solution is known from CH-PS 563 753.

Der Erfindung liegt die Aufgabe zugrunde, eine Trageinrichtung der gattungsgemäßen Art zu schaffen, bei der bei vereinfachtem Aufbau die Betätigungsstifte von Rückenlehnengasfeder und Sitzgasfeder jeweils gesondert arretierbar sind.The invention has for its object to provide a support device of the generic type, in which the actuating pins of the backrest gas spring and seat gas spring can each be separately locked with a simplified structure.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Der Kern der Erfindung liegt darin, daß nicht der Betätigungshebel selber in der Stellung arretiert wird, in der der eine oder andere Betätigungsstift arretiert ist. Der Betätigungshebel wird vielmehr nur zum Verschwenken der Zwischenhebel benutzt, die in ihrer völlig ausgelenkten Stellung dann selber mittels des jeweiligen Rasthebels in dieser ausgelenkten Stellung einrasten, in der also dann der zugeordnete Betätigungsstift einer Gasfeder eingerastet ist. Diese Ausgestaltung ermöglicht es auch, den Betätigungshebel zur Längenverstellung der Stuhlsäule einzusetzen, da er ja ständig zur Verfügung steht; auch wenn Rückenlehnengasfeder und/oder Sitzgasfeder auf Wipp-Betrieb gestellt sind, steht der Betätigungshebel für weitere Funktionen, beispielsweise die Höhenverstellung der Stuhlsäule zur Verfügung.This object is achieved by the characterizing features of claim 1. The essence of the invention is that the actuating lever itself is not locked in the position in which one or the other actuating pin is locked. The actuating lever is rather used only for pivoting the intermediate lever, which in its fully deflected position then latches itself in this deflected position by means of the respective latching lever, in which case the associated actuating pin of a gas spring is then engaged. This configuration also makes it possible to use the actuating lever for adjusting the length of the chair column, since it is always available; Even if the backrest gas spring and / or seat gas spring are set to rocking operation, the actuating lever is available for further functions, for example the height adjustment of the chair column.

Die Maßnahmen nach Anspruch 2 führen dazu, daß zur Längenverstellung von Rückenlehnengasfeder oder Sitzgasfeder der Betätigungshebel lediglich in der entsprechenden Horizontalen ausgelenkt wird, wobei zur Längenverstellung die Auslenkung nicht so weit erfolgt wie zur einrastenden Festlegung des Zwischenhebels. Die Lösung der Einrastung erfolgt dann durch eine einfache Aufwärtsbewegung des entsprechenden Betätigungsabschnittes des Betätigungshebels gegen den oder die Rasthebel.The measures according to claim 2 result in that for the length adjustment of the backrest gas spring or seat gas spring, the actuating lever is deflected only in the corresponding horizontal direction, the length adjustment not causing the deflection to the extent that the intermediate lever is locked in place. The latching is then released by a simple upward movement of the corresponding actuating section of the actuating lever against the latching lever or latches.

Die erfindungsgemäßen Maßnahmen ermöglichen es, den Betätigungshebel selber in an sich bekannter Weise entsprechend Anspruch 3 auszugestalten.The measures according to the invention make it possible to design the actuating lever itself in a manner known per se in accordance with claim 3.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung. Es zeigt

Auf einer gehäuseartig ausgebildeten Trageinrichtung 1 ist eine Stützplatte 2 für einen Sitz 3 eines Bürostuhls um eine Schwenkachse 4 neigungsverstellbar gelagert.An der Trageinrichtung 1 ist weiterhin ein Rückenlehnenträger 5 um eine Schwenkachse 6 in seiner Neigung verstellbar gelagert. Die Schwenkachsen 4, 6 sind parallel zueinander angeordnet und verlaufen senkrecht zur Hauptmittelebene des Bürostuhls. Die Trageinrichtung 1 ist auf einer höhenverstellbaren Stuhlsäule 7 abgestützt, die im wesentlichen durch eine längenverstellbare Gasfeder gebildet ist, die wiederum in einem mit einem Fußgestell verbundenen bzw. verbindbaren Führungsrohr abgestützt ist.A support plate 2 for a seat 3 of an office chair is mounted so as to be adjustable in inclination about a pivot axis 4 on a housing-like support device 1. On the support device 1, a backrest support 5 is furthermore adjustable in its inclination about a pivot axis 6. The pivot axes 4, 6 are arranged parallel to one another and run perpendicular to the main central plane of the office chair. The carrying device 1 is supported on a height-adjustable chair column 7, which is essentially formed by a length-adjustable gas spring, which in turn is supported in a guide tube connected or connectable to a base frame.

Aufbau und Wirkungsweise dieser handelsüblichen Gasfedern ist beispielsweise in der DE-PS 18 12 282 (entsprechend US-PS 3 656 593) dargestellt und beschrieben. Die Ausgestaltung einer solchen ebenfalls handelsüblichen Stuhlsäule mit Führungsrohr ist beispielsweise aus der DE-PS 19 31 o12 (entsprechend US-PS 3 711 o54) bekannt. Die als Stuhlsäule 7 dienende Gasfeder ist an ihrem oberen Ende mit einem konusförmigen Halteabschnitt 8 versehen, der in einer entsprechenden konusförmigen Aufnahme 9 der Trageinrichtung 1 gehalten ist. Die Stuhlsäule 7 ragt senkrecht nach unten aus der Trageinrichtung 1 heraus. Aus dem Halteabschnitt 8 ragt koaxial zur Mittel-Längs-Achse 1o der Stuhlsäule 7 nach oben ein in Achsrichtung verschiebbarer Betätigungsstift 11 für die Längenverstellung der Stuhlsäule 7 heraus.The structure and mode of operation of these commercially available gas springs is shown and described, for example, in DE-PS 18 12 282 (corresponding to US Pat. No. 3,656,593). The design of such a likewise commercially available chair column with guide tube is known, for example, from DE-PS 19 31 o12 (corresponding to US Pat. No. 3,711,054). The gas spring serving as a chair column 7 is provided at its upper end with a conical holding section 8 which is held in a corresponding conical receptacle 9 of the carrying device 1. The chair column 7 protrudes vertically downward from the support device 1. An actuating pin 11 for the length adjustment of the chair column 7 protrudes upward from the holding section 8 coaxially to the central longitudinal axis 10 of the chair column 7.

Die Stützplatte 2 für den Sitz 3 ist mittels einer Sitzgasfeder 12 um die Schwenkachse 4 verschwenkbar. Das freie Ende der Kolbenstange 13 der Sitzgasfeder 12 ist hierzu mittels eines Schwenkgelenks 14 mit der Stützplatte 2 in deren vorderen, also dem Rückenlehnenträger 5 abgewandten Bereich verbunden. Das andere Ende der Sitzgasfeder 12 ist mittels eines Kugelgelenks 15 schwenkbar mit der Trageinrichtung 1 verbunden, so daß das im wesentlichen zylindrische Gehäuse 16 der Sitzgasfeder 12 gegenüber der Trageinrichtung 1 nur verschwenkbar, aber nicht in seiner eigenen Längsrichtung verschiebbar ist. Die Sitzgasfeder 12 ist längenverstellbar und vom gleichen Grundaufbau wie die Stuhlsäule 7, d.h. ihr Aufbau enti spricht ebenfalls der DE-PS 18 12 282 (entsprechend US-PS 3 656 593). Ein in Richtung der Mittel-Längs-Achse 17 der Sitzgasfeder 12 verschiebbarer Betätigungsstift18 zur Auslösung bzw. Beendigung einer Längenverstellung der Sitzgasfeder 12 ragt durch das Kugelgelenk 15 hini durch in die Trageinrichtung 1 hinein.The support plate 2 for the seat 3 can be pivoted about the pivot axis 4 by means of a seat gas spring 12. For this purpose, the free end of the piston rod 13 of the seat gas spring 12 is connected by means of a swivel joint 14 to the support plate 2 in its front region, that is to say the region facing away from the backrest support 5. The other end of the seat gas spring 12 is pivotally connected to the support device 1 by means of a ball joint 15, so that the essentially cylindrical housing 16 of the seat gas spring 12 can only be pivoted relative to the support device 1, but cannot be displaced in its own longitudinal direction. The seat gas spring 12 is adjustable in length and of the same basic structure as the chair column 7, i.e. their structure enti also speaks DE-PS 18 12 282 (corresponding to US-PS 3,656,593). An actuating pin 18 which can be displaced in the direction of the central longitudinal axis 17 of the seat gas spring 12 for triggering or ending a length adjustment of the seat gas spring 12 projects through the ball joint 15 into the carrying device 1.

Für die Neigungsverstellung des Rückenlehnenträgers 5 ist eine Rückenlehnengasfeder 19 vorgesehen, die in ihrem Aufbau und in ihrer Funktion der Sitzgasfeder 12 entspricht. Die Rückenlehnengasfeder 19 ist mittels eines am freien Ende ihrer Kolbenstange 2o angebrachten Schwenkgelenks 21 mit dem Rückenlehnenträger in ausreichendem Abstand von der Schwenkachse 6 verbunden. Ihr zylindrisches Gehäuse 22 ist am gegenüberliegenden Ende mittels eines Kugelgelenks 23 mit der Trageinrichtung 1 schwenkbar aber in Richtung ihrer Mittel-Längs-Achse 24 unverschiebbar verbunden. Ein Betätigungsstift 25 für die Längenverstellung der Rückenlehnengasfeder 19 ragt in die Trageinrichtung hinein. Die drei Mittel-Längs-Achsen 1.o, 17, 24 liegen in einer gemeinsamen Ebene, die mit der bereits erwähnten Haupt-Mittelebene des Bürostuhls zusammenfällt.For the inclination adjustment of the backrest support 5, a backrest gas spring 19 is provided, which corresponds in structure and function to the seat gas spring 12. The backrest gas spring 19 is connected to the backrest support at a sufficient distance from the pivot axis 6 by means of a swivel joint 21 attached to the free end of its piston rod 20. Its cylindrical housing 22 is pivotally connected to the support device 1 at the opposite end by means of a ball joint 23, but is non-displaceably connected in the direction of its central longitudinal axis 24. An actuating pin 25 for the length adjustment of the backrest gas spring 19 protrudes into the carrying device. The three central longitudinal axes 1.o, 17, 24 lie in a common plane, which coincides with the main central plane of the office chair already mentioned.

Zur mittelbaren bzw. unmittelbaren Betätigung der Betätigungsstifte 11, 18, 25 ist ein Betätigungshebel 26 vorgesehen, dessen Mittel-Längs-Achse 27 etwa senkrecht zu den drei Achsen 10, 17, 24, also etwa senkrecht zur mehrfach erwähnten Haupt-Symmetrie-Ebene des Stuhles verläuft. Ein am freien äußeren Ende des Betätigungshebels 26 angebrachter Griff 28 ist also etwa seitlich unterhalb der Stützplatte 2 bzw. des Sitzes 3 angeordnet, so daß der Betätigungshebel 26 von einer auf einem Stuhl sitzenden Person bequem erreicht und bedient werden kann. Der Betäigungshebel 26 ist mittels Kugelgelenks 29 allseitig schwenkbar in der Trageinrichtung 1 gelagert. Zur mittelbaren bzw. unmittelbaren Betätigung der Betätigungsstifte 11, 18, 25 ragt ein Betätigungsabschnitt 3o des Betätigungshebels 26 über das Kugelgelenk 29 hinaus in die Trageinrichtung 1 hinein. Der Betätigungshebel 26 ist also im Bereich zwischen den Betätigungsstiften 11, 18, 25 und dem durch den Griff 28 gebildeten äußeren Ende gelagert.For the indirect or direct actuation of the actuating pins 11, 18, 25, an actuating lever 26 is provided, the central longitudinal axis 27 of which is approximately perpendicular to the three axes 10 , 17, 24, that is to say approximately perpendicular to the main symmetry plane mentioned several times of the chair. A handle 28 attached to the free outer end of the actuating lever 26 is thus arranged approximately laterally below the support plate 2 or the seat 3, so that the actuating lever 26 can be comfortably reached and operated by a person sitting on a chair. The actuating lever 26 is pivotally supported in the carrying device 1 by means of a ball joint 29. For the indirect or direct actuation of the actuating pins 11, 18, 25, an actuating section 3o of the actuating lever 26 projects beyond the ball joint 29 into the carrying device 1. The actuating lever 26 is thus mounted in the area between the actuating pins 11, 18, 25 and the outer end formed by the handle 28.

Der Betätigungsabschnitt 3o weist an seinem freien Ende einen verjüngt ausgebildeten Führungsabschnitt 31 auf, der auf einer Führungsbahn 32 geführt wird. Diese Führungsbahn ist im wesentlichen - wie in Fig. 2 angedeutet ist - horizontal ausgebildet und weist einen mittleren, dem Betätigungsstift 11 der Stuhlsäule 7 zugeordneten sich nach unten erstreckenden Bahnabschnitt 33 auf. Wenn der Betätigungshebel 26 aus seiner in der Zeichnung dargestellten Mittellage derart in einer Vertikalebene verschwenkt wird, daß der Griff 28 nach oben gezogen und damit der Führungsabschnitt 31 in den Bahnabschnitt 33 hineingeführt wird, dann wird also der Betätigungsabschnitt 3o des Betätigungshebels 26 nach unten geschwenkt, wodurch der Betätigungsstift 11 der Stuhlsäule 7 in letztere hineingeschoben wird, wodurch deren internes Betätigungsventil geöffnet wird. Die Stuhlsäule 7 kann jetzt in der üblichen bekannten Weise verlängert oder verkürzt werden, wodurch entsprechend die Stützplatte 2 mit dem Sitz 3 in ihrer Höhenlage verstellt wird.The actuating section 3o has at its free end a tapered guide section 31 which is guided on a guide track 32. This guideway is essentially horizontal, as indicated in FIG. 2, and has a central, downwardly extending path section 33 associated with the actuating pin 11 of the chair column 7. If the actuating lever 26 is pivoted from its central position shown in the drawing in a vertical plane in such a way that the handle 28 is pulled upwards and thus the guide section 31 is inserted into the track section 33, then the actuating section 30 of the actuating lever 26 is pivoted downward, whereby the actuating pin 11 of the chair column 7 is pushed into the latter, whereby the internal actuating valve is opened. The chair column 7 can now be lengthened or shortened in the usual known manner, as a result of which the support plate 2 with the seat 3 is adjusted in its height.

.Im unteren Bereich der Trageinrichtung sind beiderseits der Aufnahme 9, also auch beiderseits der Stuhlsäule 7 spiegelsymmetrisch zueinander Zwischenhebel 34, 35 um ihre unteren halbkreisförmig gebogenen Enden 36, 37 schwenkbar gelagert, und zwar zu den Betätigungsstiften 18 bzw. 25 der Sitzgasfeder 12 bzw. der Rückenlehnengasfeder 19 hin. Deren Betätigungsstifte 18 bzw. 25 liegen an mittleren, bezogen auf die Betätigungsstifte 18, 25 nach außen durchgebogenen Anlageflächen 38, 39 der Zwischenhebel 34, 35 an. Aufgrund der Durchbiegung der Anlageflächen 38, 39 liegen die Betätigungsstifte 18 bzw. 25 auch in unterschiedlichen Schwenkstellungen der Sitzgasfeder 12 bzw. Rückenlehnengasfeder 19 an den Anlageflächen 38 bzw. 39 an, ohne daß aufgrund der unterschiedlichen Schwenkstellungen eine Verschiebung also Betätigung der Betätigungsstifte 18 bzw. 25 bewirkt wird. Die Krümmung der Anlageflächen 38, 39 verläuft also etwa angenähert konzentrisch zu den jeweiligen Kugelgelenken 15 bzw. 23.In the lower area of the carrying device, on both sides of the receptacle 9, that is also on both sides of the chair column 7, mirror levers 34, 35 are pivotably mounted about their lower semicircular ends 36, 37, namely to the actuating pins 18 and 25 of the seat gas spring 12 and the backrest gas spring 19 out. Their actuating pins 18 and 25 rest against middle, with respect to the actuating pins 18, 25 outwardly bent contact surfaces 38, 39 of the intermediate lever 34, 35. Due to the deflection of the contact surfaces 38, 39, the actuating pins 18 and 25 are also in different pivoting positions of the seat gas spring 12 or backrest gas spring 19 on the contact surfaces 38 and 39, without the difference Lichen swivel positions a shift so actuation of the actuating pins 18 and 25 is effected. The curvature of the contact surfaces 38, 39 thus runs approximately approximately concentrically with the respective ball joints 15 and 23, respectively.

Die oberen freien Enden der Zwischenhebel 34, 35 werden durch von den Anlageflächen 38, 39 jeweils nach innen und oben grkröpften Rastabschnitte 40, 41 gebildet, die beiderseits des in der Ruhelage befindlichen Betätigungsabschnitts 3o des Betätigungshebels 26 angeordnet sind und gegenüber letzterem in der Ruhelage ein geringes Spiel aufweisen. Wenn der Betätigungshebel 26 etwa in der Horizontalen - relativ zur Stützplatte 2 des Sitzes 3 nach vorn oder hinten - verschwenkt wird, dann wird entweder der Zwischenhebel 34 unter entsprechendem Betätigen des Betätigungsstiftes 18 der Sitzgasfeder 12 oder der Zwischenhebel 35 unter entsprechendem Betätigen des Betätigungsstiftes 25 der Rückenlehnengasfeder 19 aus seiner Ruhelage nach außen verschwenkt. Bei einer solchen entsprechenden Betätigung kann daher entweder die Neigung der Stützplatte 2 mit dem Sitz 3 oder die Neigung des Rückenlehnenträgers 5 jeweils um die Schwenkachsen 4 bzw. 6 verändert werden. Wenn der Griff 28 des Betätigungshebels 26 von der bedienenden Person losgelassen wird, wird er jeweils von dem Betätigungsstift 18 bzw. 25 über den entsprechenden Zwischenhebel 34 bzw. 35 in seine Mittellage verschoben. Das vom jeweiligen Betätigungsstift 18 bzw. 25 betätigte Ventil der entsprechenden Gasfeder ist dann geschlossen. Die Stützplatte 2 bzw. der Rückenlehnenträger 5 werden wieder in einer neuen Neigungslage fixiert. Bei den horizontalen Schwenkbewegungen des Betätigungsabschnittes 3o des Betätigungshebels 26 wird dieser auf beiderseits des etwa vertikal nach unten gerichteten Bahnabschnitts 33 ausgebildeten Bahnabschnitten 42 bzw. 43 der Führungsbahn 32 geführ:.The upper free ends of the intermediate levers 34, 35 are carried by the bearing surfaces 38, 39 respectively inwardly and upwardly grkröpften latching sections 4 0, 41 are formed, which are arranged on both sides of the actuating portion located in the rest position 3o of the actuating lever 26 and against the latter in the rest position have little play. If the actuating lever 26 is pivoted approximately horizontally - relative to the support plate 2 of the seat 3 forwards or backwards - then either the intermediate lever 34 with corresponding actuation of the actuating pin 18 of the seat gas spring 12 or the intermediate lever 35 with corresponding actuation of the actuating pin 25 of the Backrest gas spring 19 pivoted out of its rest position. With such a corresponding actuation, either the inclination of the support plate 2 with the seat 3 or the inclination of the backrest support 5 can be changed in each case about the pivot axes 4 or 6. When the handle 28 of the actuating lever 26 is released by the operator, it is shifted into its central position by the actuating pin 18 or 25 via the corresponding intermediate lever 34 or 35. The valve of the corresponding gas spring actuated by the respective actuating pin 18 or 25 is then closed. The support plate 2 or the backrest support 5 are again fixed in a new inclination position. During the horizontal pivoting movements of the actuating section 3o of the actuating lever 26, the latter is formed on both sides of the approximately vertically downwardly directed path section 33 cut 42 or 43 of the guideway 32.

Oberhalb des Betätigungshebels sind zwei gekreuzt angeordnete Rasthebel 44, 45 in der Trageinrichtung 1 angeordnet, die mittels ihrer oberen äußeren, gebogen ausgebildeten Enden 46, 47 in der Trageinrichtung 1 schwenkbar abgestützt sind. Sie werden mittels einer konzentrisch zur Mittel-Längs-Achse lo angeordneten Druckfeder 48 nach unten gedrückt, so daß ihre unteren, etwa horizontal angeordneten, und leicht nach oben gekröpften Enden 49, 5o gegen die Rastabschnitte 4o bzw. 41 anliegen. Die Kreuzungsstelle der beiden Rasthebel 44, 45 befindet sich unmittelbar oberhalb des Betätigungsabschnittes 3o des Betätigungshebels 26.Above the actuating lever, two crossed locking levers 44, 45 are arranged in the carrying device 1, which are pivotably supported in the carrying device 1 by means of their upper outer, curved ends 46, 47. They are pressed down by means of a compression spring 48 arranged concentrically to the central longitudinal axis lo, so that their lower, approximately horizontally arranged, and slightly bent ends 49, 5o abut against the latching sections 4o and 41, respectively. The crossing point of the two locking levers 44, 45 is located directly above the actuating section 30 of the actuating lever 26.

Wenn der Betätigungshebel 26 in der Horizontalen so verschwenkt wird, daß der der Sitzgasfeder 12 zugeordnete Zwischenhebel 34 unter Betätigung des entsprechenden Betätigungsstiftes 18 verschwenkt wird, dann wird während dieser Verschwenkbewegung das freie Ende 49 des Rasthebels 44 auf dem Rastabschnitt 4o des Zwischenhebels angehoben und drückt gegen diesen, da der Rasthebel 44 durch die Verschwenkung des Zwischenhebels 34 gegen den Druck der Druckfeder 48 leicht nach oben ausgelenkt wird. Soll nur eine Längenverstellung der Sitzgasfeder 12, also eine Neigungsverstellung der Stützplatte 2 des Sitzes 3 erfolgen, bleibt es dabei. Wenn dagegen der Betätigungsstift 18 in seiner in die Sitzgasfeder 12 eingeschobenen Stellung arretiert werden soll, wenn also das innere Ventil der Sitzgasfeder 12 ständig geöffnet sein soll, dann wird der Betätigungshebel 26 so weit horizontal verschwenkt, daß der Rastabschnitt 4o des Zwischenhebels in Eingriff mit dem gekröpften Ende 49 des Rasthebels 44 gebracht wird. Der Rasthebel 44 wird hierbei durch die Druckfeder 48 nach unten gedrückt und setzt sich mit seinem gekröpften Ende 49 auf und hinter den Rastabschnitt 4o des Zwischenhebels 34. In gleicher Weise kann der Betätigungsstift 25 der Rückenlehnengasfeder 19 lediglich für eine Neigungsverstellung des Rückenlehnenträgers 5 eingeschoben oder wahlweise in der eingeschobenen Stellung arretiert werden, in der dann das untere gekröpfte Ende 5o des Rasthebels 45 auf und hinter dem Rastabschnitt 41 des Zwischenhebels 35 sitzt. Wie in Fig. 4 dargestellt ist. Zum Lösen der Arretierung eines oder beider Zwischenhebel 34 bzw. 35 und damit eines oder beider Betätigungsstifte 18 bzw. 25 wird der Griff 28 des Betätigungshebels 26 in der Mittellage nach_unten gedrückt, wodurch sein Betätigungsabschnitt 3o nach oben gegen den Kreuzungsbereich der Rasthebel 44, 45 gedrückt wird. Hierdurch werden diese und damit deren gekröpfte Enden 49, 5o nach oben gehoben, so daß ein oder beide Betätigungsstifte 18 bzw. 29 den bzw. die Zwischenhebel 34 bzw. 35 wieder in ihre Ruhelage drücken können. Der Betätigungshebel 26 wird durch ein elastisches Kissen 51, beispielsweise aus geschäumtem Polyurethan-Schaum, jeweils wieder in seine mittlere Ruhelage gebracht bzw. dort gehalten.If the actuating lever 26 is pivoted horizontally so that the intermediate lever 34 assigned to the seat gas spring 12 is pivoted by actuating the corresponding actuating pin 18, then during this pivoting movement the free end 49 of the latching lever 44 is raised on the latching section 4o of the intermediate lever and presses against this, because the locking lever 44 is slightly deflected upwards by the pivoting of the intermediate lever 34 against the pressure of the compression spring 48. If only a length adjustment of the seat gas spring 12, that is to say an inclination adjustment of the support plate 2 of the seat 3, is to be made, it remains so. If, on the other hand, the actuating pin 18 is to be locked in its position pushed into the seat gas spring 12, that is if the inner valve of the seat gas spring 12 is to be constantly open, then the actuating lever 26 is pivoted horizontally so far that the latching section 4o of the intermediate lever engages with the cranked end 49 of the locking lever 44 is brought. The locking lever 44 is pressed down by the compression spring 48 and sits with its cranked end 49 on and behind the locking section 4o of the intermediate lever 34. In the same way, the actuating pin 25 of the backrest gas spring 19 can only be inserted for an inclination adjustment of the backrest support 5 or alternatively be locked in the inserted position, in which the lower cranked end 50 of the locking lever 45 then sits on and behind the locking section 41 of the intermediate lever 35. As shown in Fig. 4. To release the locking of one or both intermediate levers 34 and 35 and thus one or both actuating pins 18 and 25, the handle 28 of the actuating lever 26 is pressed downward in the central position, as a result of which its actuating section 3o is pressed upwards against the crossing region of the latching levers 44, 45 becomes. As a result, these and thus their cranked ends 49, 50 are lifted upward, so that one or both actuating pins 18 and 29 can push the intermediate lever or levers 34 and 35 back into their rest position. The actuating lever 26 is brought back into its central rest position or held there by an elastic cushion 51, for example made of foamed polyurethane foam.
