Description

Die Erfindung betrifft ein Sitzmöbel nach dem Oberbegriff des Anspruchs 1.The invention relates to seating furniture according to the preamble of claim 1.

Ein derartiges Sitzmöbel ist bekannt z. B. aus dem DE-U-7711 928. Bei dem bekannten Sitzmöbel sind die Stützteile und die Armauflageteile aus biegeweichem Material, und biegeweich miteinander verbunden. Die biegeweichen Armlehnen ergeben jedoch erhebliche Materialprobleme. Sie können z. B. aus einem Stahlfederband als Kern aufgebaut sein, das mit elastischem Material, z. B. Integralschaum, umkleidet ist. Diese Konstruktion neigt jedoch leicht zum Ausknicken, wenn die oft sehr grossen Belastungskräfte aufgenommen werden müssen. Man ist auch sehr eingeengt bei der Materialauswahl der Umkleidung. Die üblichen, kostengünstigen Werkstoffe wie Holz, feste Kunststoffe u. dgl. scheiden wegen fehlender Elastizität aus. Diese Armlehnenkonstruktion ist daher auch teuer. Hinzu kommt, dass die in Abhängigkeit von der Lehnenneigung unterschiedlich deformierten Armlehnen auch ästhetisch nicht befriedigen.Such seating is known for. B. from DE-U-7711 928. In the known seating, the support parts and the armrest parts are made of flexible material, and flexible connected to each other. However, the flexible armrests result in considerable material problems. You can e.g. B. be constructed from a steel spring band as a core, which with elastic material, for. B. integral foam, is covered. However, this construction tends to buckle easily when the often very large loading forces have to be absorbed. One is also very restricted in the choice of materials for the casing. The usual, inexpensive materials such as wood, solid plastics u. The like. Eliminate due to lack of elasticity. This armrest construction is therefore also expensive. In addition, the armrests, which are deformed differently depending on the backrest angle, are also not aesthetically satisfactory.

Andererseits kommt das bekannte Sitzmöbel dem Benutzerbedürfnis entgegen, eine ständige Verbindung der Armlehnen mit Sitz und Rückenlehne zu gewährleisten, auch wenn diese gegeneinander geneigt werden. Ist dies nämlich nicht der Fall, ist die Armlehne beispielsweise nur mit dem Sitz verbunden, so ergibt sich beim Neigen der Rückenlehne ein Spalt zur Armlehne, oder die Armlehne ragt bei Senkrechtstellung der Rückenlehne über diese nach hinten hinaus. Daraus ergeben sich gefährliche Klemmstellen. Ist die Armlehne jedoch an der Rückenlehne befestigt, so ragt sie schräg nach oben, wenn diese geneigt wird. Eine sich setzende Person kann dann mit der Hosentasche hängen bleiben. Darüber hinaus ist es auch ein mechanisches Problem, die erheblichen Abstützkräfte des Benutzers über die Rückenlehne in das Stuhl-Unterteil einzuleiten. Schliesslich sind die genannten Lösungen auch ästhetisch höchst unbefriedigend.On the other hand, the known seating meets the user need to ensure a permanent connection of the armrests with the seat and backrest, even if they are inclined towards each other. If this is not the case, the armrest is only connected to the seat, for example, when the backrest is inclined there is a gap to the armrest, or the armrest projects beyond the backrest when the backrest is in a vertical position. This results in dangerous clamping points. However, if the armrest is attached to the backrest, it projects upwards at an angle when it is tilted. A person sitting down can then get stuck with his pocket. In addition, it is also a mechanical problem to introduce the considerable support forces of the user via the backrest into the lower part of the chair. Finally, the solutions mentioned are also aesthetically extremely unsatisfactory.

Die im Garten- und Freizeitmöbelbereich bekannten Lösungen, dass die Armauflagen drehbar mit der Rückenlehne und den vorn nach oben gezogenen Sitzbeinen verbunden werden, sind bei Sitzmöbeln mit zentraler Standsäule, insbesondere Drehstühlen und Drehsesseln, natürlich auch nicht verwendbar. Eine Abwandlung solcher Lösungen für Sitzmöbel mit zentraler Standsäule derart, dass eine dreigelenkige Armlehnenkonstruktion vorgesehen wird, ist sowohl aus Kostengründen, als auch aus Gründen der Stabilität und Aesthetik nicht akzeptabel.The solutions known in the garden and leisure furniture sector, that the armrests can be rotatably connected to the backrest and the front seat legs, can of course also not be used for seating furniture with a central column, especially swivel chairs and swivel armchairs. A modification of such solutions for seating furniture with a central pedestal in such a way that a three-articulated armrest construction is provided is not acceptable both for reasons of cost and for reasons of stability and aesthetics.

Auch die aus dem Dokument CH-A-316114 bekannte Lösung vermag die genannten Probleme nicht zu beseitigen. In diesem Dokument wird ein Sitzmöbel mit zentraler Standsäule beschrieben, welches einen Sitz, eine Rückenlehne und zwei Armlehnen aufweist, wobei die Neigung der Rückenlehne in bezug auf den Sitz veränderbar ist, und die vorderen, nach oben strebenden Stützteile und die Armauflageteile dieser Armlehnen aus prinzipiell starrem Material hergestellt, starr miteinander verbunden und unbeweglich mit einem Querverband am Sitz befestigt sind. Da jedoch der Anschlusspunkt der starren Armlehnen an der Rückenlehne als fester Drehpunkt genommen wird, lässt sich eine Bewegung des auf einer Kugelschiene parallel nach vorn verschiebbaren Sitzes und damit eine Neigung der Rückenlehne nur dann ermöglichen, wenn das prinzipiell starre Material der Armlehnen doch ein gewisses Mass an Verformbarkeit aufweist. Dann gelten aber insoweit wieder die eingangs zu dem aus dem Dokument DE-A-7 711 928 bekannten Sitzmöbel angeführten Nachteile.Even the solution known from document CH-A-316114 cannot solve the problems mentioned. In this document, a piece of seating furniture with a central column is described, which has a seat, a backrest and two armrests, the inclination of the backrest with respect to the seat being changeable, and the front, upward-reaching support parts and the armrest parts of these armrests in principle made of rigid material, rigidly connected to each other and immovably attached to the seat with a cross brace. However, since the connection point of the rigid armrests to the backrest is taken as a fixed fulcrum, a movement of the seat, which can be moved forwards parallel on a ball rail, and thus an inclination of the backrest can only be made possible if the basically rigid material of the armrests is nevertheless a certain amount has deformability. Then, however, the disadvantages mentioned at the beginning of the seating furniture known from document DE-A-7 711 928 apply again.

Es ist die Aufgabe der Erfindung, ein Sitzmöbel der eingangs genannten Art derart zu verbessern, dass sich Sitz und Rückenlehne in ihrer Position gegeneinander verändern können, und die Armlehnen diese Bewegung mitmachen, ohne dass aber die geschilderten Material-, Stabilitäts-, Kosten-, oder ästhetischen Probleme auftreten, aber auch Klemmstellen und Gefährdungen des Benutzers durch Eingriffe der Armlehnen in die Hosentaschen desselben vermieden werden.It is the object of the invention to improve seating furniture of the type mentioned at the outset in such a way that the position of the seat and backrest can change relative to one another, and the armrests join in this movement, but without the material, stability, cost, or aesthetic problems occur, but also clamping points and hazards to the user can be avoided by interfering with the armrests in the pockets of the pants.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Die Kulissenführung kann sich entweder im Sitz oder in der Lehne befinden. In den meisten Fällen ist es aber vorteilhaft, die Kulissenführung in den Sitz zu legen, wo sie dann annähernd waagerecht verläuft. Damit ergibt sich für den Benutzer in vorteilhafter Weise eine gleichbleibende Armlehnenhöhe. Der ebenfalls annähernd waagerecht verlaufende Sitz bietet darüber hinaus auch konstruktiv bessere Möglichkeiten als die etwa senkrecht stehende Rückenlehne. Festigkeitsmässig und funktionell sehr vorteilhaft ist es, dabei korrespondierende Drehlager der Armlehnen, insbesondere deren Lagerzapfen, starr miteinander zu verbinden.The backdrop guide can either be in the seat or in the backrest. In most cases, however, it is advantageous to place the slide guide in the seat, where it then runs approximately horizontally. This advantageously results in a constant armrest height for the user. The almost horizontal seat also offers better design options than the approximately vertical backrest. In terms of strength and function, it is very advantageous to rigidly connect corresponding pivot bearings of the armrests, in particular their bearing journals.

Erfindungsgemäss werden demnach die Armlehnen als in sich steife Verbindungsteile zwischen Sitz und Rückenlehne ausgelegt. Ein drittes Gelenk vorn oben an der Verbindungsstelle von Stützteil und Armauflageteil ist hier nicht vonnöten. Dadurch werden nicht nur konstruktiver Aufwand und Kosten gespart, sondern es ergeben sich auch sehr viel bessere gestalterische Möglichkeiten.According to the invention, the armrests are designed as rigid connection parts between the seat and the backrest. A third hinge at the front at the junction of the support part and armrest part is not necessary here. This not only saves construction effort and costs, it also results in much better design options.

Gegenüber der eingangs geschilderten Ausführungsform mit zumindest in Teilbereichen elastischen Armlehnen bestehen die Vorteile, dass die Armlehnen ausschliesslich auf die Festigkeitsbelange der einwirkenden Kräfte hin ausgelegt werden können. Damit wird ein Ausknicken oder Ausbeulen vermieden. Es besteht auch kein Zwang für ein elastisches Umhüllungsmaterial der Armlehnen. Weiches Umhüllungsmaterial kann in Verbindung mit einem tragenden Kern genauso gut verwendet werden die steifes und selbsttragendes Material, etwa Holz, Kunststoff, Metall usw. Die Erfindung bietet gerade in Zeiten von sich verschiebenden Materialkosten den Vorteil, konstruktiv und preislich die günstigsten Materialen auswählen zu können ohne Rücksicht auf bestimmte Kombinationen. Es werden auch die Lager übermässig beanspruchende Kräfte vermieden, die dann entstehen, wenn Verformungskräfte zur elastischen Verformung von biegeweichen Armlehnen aufgewandt werden müssen.Compared to the embodiment described at the beginning with armrests which are elastic at least in some areas, there are the advantages that the armrests can be designed exclusively for the strength requirements of the forces acting on them. This prevents buckling or bulging. There is also no requirement for an elastic covering material for the armrests. Soft wrapping material can be used in conjunction with a tra The rigid and self-supporting material, such as wood, plastic, metal, etc., are used just as well. The invention offers the advantage, particularly in times of shifting material costs, of being able to select the cheapest materials in terms of design and price, regardless of certain combinations. It also avoids excessive stress on the bearings, which arise when deformation forces have to be applied to the elastic deformation of flexible armrests.

Optisch und von der Klemmgefahr her vorteilhaft ist, bei aussen an Sitz und Rückenlehne angebrachten Armlehnen den Längsschlitz der Kulissenführung durch die Armlehne in allen Positionen abzudecken. Besonders vorteilhaft ist hier die sogenannte Ringarmlehne, bei welcher dann nur der Lagerdrehpunkt geeignet gewählt werden muss. Aber auch bei anderen Armlehnen kann die Abdeckung dadurch erreicht werden, dass dem Stützteil der Armlehne ein Basisteil zugeordnet ist, welches derart gestaltet ist, dass der in der Kulisse gelagerte Drehpunkt beständig abgedeckt ist.Visually and from the risk of pinching, it is advantageous to cover the longitudinal slot of the link guide in all positions with the armrests attached to the outside of the seat and backrest. The so-called ring armrest is particularly advantageous here, in which case only the bearing pivot point then has to be suitably selected. But also with other armrests, the cover can be achieved by assigning a base part to the support part of the armrest, which is designed in such a way that the pivot point stored in the link is covered constantly.

Armlehnen werden sehr oft nicht rein vertikal, sondern häufig etwas schräg nach aussen belastet, wenn sich z. B. ein Benutzer beim Aufstehen aufstützt. Hierzu ist es von grossem Vorteil, die korrespondierenden Lager beider Armlehnen durch eine starre Verbindung miteinander zu verbinden. Denn hierdurch entsteht festigkeitsmässig ein Verband, der Biegekräfte auf die Lager und ein daraus resultierendes Ankippen der Armlehnen sowie hohe Lager-Kantenbelastungen vermeidet. Es genügt dabei, wenn nur ein korrespondierendes Drehlagerpaar verbunden wird. Vorteilhaft ist es auch, das Lagerpaar an den Sitz zu binden, weil dabei die starre Verbindung, insbesondere eine Stange, in oder noch besser unter den Sitz verlegt werden kann, wo sie besser ausserhalb des Sichtbereiches liegt als an der Rückenlehne.Armrests are very often not loaded vertically, but often somewhat obliquely outwards, if z. B. supports a user when getting up. For this it is of great advantage to connect the corresponding bearings of both armrests to each other by means of a rigid connection. Because this creates a bond in terms of strength, which prevents bending forces on the bearings and the resulting tilting of the armrests as well as high bearing edge loads. It is sufficient if only a corresponding pair of rotary bearings is connected. It is also advantageous to tie the pair of bearings to the seat, because the rigid connection, in particular a rod, can be laid in or even better under the seat, where it is better outside the field of vision than on the backrest.

Eine vorteilhafte Ausführungsform besteht auch darin, runde Lagerbolzen vorzusehen, die jeweils in die Enden eines verbindenden runden Rohres gesteckt werden. Dies ergibt eine einfache, biegesteife und sehr kostengünstige Lösung.An advantageous embodiment also consists in providing round bearing bolts which are each inserted into the ends of a connecting round tube. This results in a simple, rigid and very inexpensive solution.

Wird zwischen links und rechts nicht unterschieden, so sind die Buchstaben bei den Bezugszeichen weggelassen.The parts of the seating furniture according to the invention appearing in pairs in the figures are identified on the left-hand side by reference symbols with the letter “a” and on the right-hand side by reference symbols with the letter “b. If no distinction is made between left and right, the letters are at the reference numerals omitted.

In Fig. 1 wird ein Sitzmöbel in Gestalt eines Drehsessels mit Sitz 1, Rückenlehne 2, Armlehnen 3 und Standsäule 13 dargestellt. Die Armlehne 3 umfasst einen vorderen, nach oben strebenden Stützteil 15, und einen damit starr verbundenen Armauflageteil 14. Beide Teile bestehen aus starrem Material, beispielsweise aus einem Metallbügel mit einer gepolsterten Armauflage aus Kunststoff.1 shows a piece of seating furniture in the form of a swivel armchair with seat 1, backrest 2, armrests 3 and pedestal 13. The armrest 3 comprises a front, upwardly striving support part 15, and an arm support part 14 rigidly connected to it. Both parts consist of rigid material, for example of a metal bracket with a padded arm support made of plastic.

Die Armauflageteile 14 sind an der Rückenlehne 2 mit dem Drehlager 4 angelenkt. Die Stützteile 15 sind mit dem Sitz 1 über die Drehlager 5 verbunden. Dieses ist im Längsschlitz der Kulissenführung 9 beweglich geführt. Der Sitz 1 und die Rückenlehne 2 können mittels einer an sich bekannten Verstelleinrichtung 20 (z. B. gemäss EP-A-0 001 846) in ihrer Position zueinander verändert werden, wobei sich der Sitzwinkel, d. h. der Winkel zwischen Sitz und Rückenlehne, mit ändert.The armrest parts 14 are articulated on the backrest 2 with the pivot bearing 4. The support parts 15 are connected to the seat 1 via the pivot bearing 5. This is movably guided in the longitudinal slot of the link guide 9. The position of the seat 1 and the backrest 2 can be changed with respect to one another by means of an adjusting device 20 known per se (for example according to EP-A-0 001 846), the seat angle, ie. H. the angle between the seat and backrest, with changes.

In Fig. 2 ist dargestellt, wie die korrespondierenden Drehlager 5a, 5b der Armlehnen 3a, 3b durch eine mechanisch starre Verbindung verbunden sind. Diese mechanisch starre Verbindung ist eine Stange 6, in diesem Fall ein Rohr, an dessen Enden Bolzen 7a, 7b vorgesehen sind, die in die Stützteile 15a, 15b der Armlehnen 3a, 3b eingreifen. An der Rückenlehne 2 sind die Armlehnen 3a, 3b mittels der Bolzen 8a, 8b angelenkt.2 shows how the corresponding pivot bearings 5a, 5b of the armrests 3a, 3b are connected by a mechanically rigid connection. This mechanically rigid connection is a rod 6, in this case a tube, at the ends of which bolts 7a, 7b are provided which engage in the support parts 15a, 15b of the armrests 3a, 3b. The armrests 3a, 3b are articulated on the backrest 2 by means of the bolts 8a, 8b.

Die Bolzen 7, 8 der Drehlager können vorteilhaft fester Bestandteil der Armlehnen 3 sein. Die Stange 6 verbindet unterhalb des Sitzpolsters innerhalb des Sitzes 1 die beiden Armlehnen 3a und 3b miteinander, indem die Bolzen 7 in das Rohr 6 von aussen nach innen geschoben und mit diesem verbunden werden. Die Verbindung von Bolzen 7 und Rohr 6 erfolgt zweckmässigerweise lösbar, beispielsweise durch eine Schraube 19, bzw. Stifte, Splinte u. dgl. Die Stange 6 kann auch unterhalb des Sitzes 1 vorgesehen sein, wo sie gleichfalls in erwünschter Weise ausserhalb des Sichtbereichs liegt.The bolts 7, 8 of the pivot bearing can advantageously be an integral part of the armrests 3. The rod 6 connects the two armrests 3a and 3b to one another below the seat cushion within the seat 1 by pushing the bolts 7 into the tube 6 from the outside inwards and connecting them. The connection of bolt 7 and tube 6 is expediently detachable, for example by a screw 19 or pins, split pins and the like. The rod 6 can also be provided underneath the seat 1, where it is also located outside the field of view in the desired manner.

Die Bolzen 7 werden im Längsschlitz der Kulissenführung 9 geführt und können sich in der Kulissenführung drehen. Die Kulissenführung 9 kann fester Bestandteil des Sitzes 1 sein, ist beispielsweise als Kunststoffteil mit Lagereigenschaften im Sitzrahmen 18 (Fig. 4b) angeordnet. Ist die Kulissenführung in der Rückenlehne vorgesehen, so wird sie im Rückenlehnenrahmen angeordnet. Die Kulissenführung kann aber auch als separates Bauteil am Sitz 1 oder an der Rückenlehne 2 angebracht sein. Wenn Sitz und/ oder Rückenlehnen aus Kunststoffschalen, z. B. aus Fiberglas oder verformten Sperrholz, bestehen, können die Kulissen vorteilhafterweise in den seitlichen Wangen der Schalen vorgesehen werden.The bolts 7 are guided in the longitudinal slot of the link guide 9 and can rotate in the link guide. The link guide 9 can be an integral part of the seat 1, for example is arranged as a plastic part with storage properties in the seat frame 18 (Fig. 4b). If the link guide is provided in the backrest, it is arranged in the backrest frame. The link guide can also be attached as a separate component on the seat 1 or on the backrest 2. If the seat and / or backrests are made of plastic shells, e.g. B. made of fiberglass or deformed plywood, the scenes can advantageously be provided in the side cheeks of the shells.

Funktionell vorteilhaft ist es, die Bolzen 7 nicht direkt in der Kulissenführung 9 zu führen, sondern zweckmässigerweise in einem Gleitstein 10 zu lagern. Der Gleitstein 10 besteht aus Kunststoff und besitzt in der Mitte eine Bohrung zur Aufnahme des Bolzens 7 und aussen zwei Flächen, welche entlang der Lagerflächen der Kulissenführung 9 gleiten. Dadurch wird eine verminderte Flächenpressung erreicht. Dies ist in Fig. 4a und 4b dargestellt. Wie ersichtlich, ist dabei der Bolzen 7 in eine Ausnehmung 17 der Armlehne 3b eingeschoben und mit dieser stoffschlüssig verbunden, z. B. verschweisst. Die Kulissenführung 9 ist formschlüssig im Rahmen 18 des Sitzes 1 vorgesehen.It is functionally advantageous not to guide the bolts 7 directly in the link guide 9, but rather to store them in a sliding block 10. The sliding block 10 is made of plastic and has a hole in the middle for receiving the bolt 7 and two surfaces on the outside which slide along the bearing surfaces of the link guide 9. This results in a reduced surface pressure. This is shown in Figures 4a and 4b. As can be seen, the bolt 7 is inserted into a recess 17 of the armrest 3b and connected to this materially, z. B. welded. The link guide 9 is positively provided in the frame 18 of the seat 1.

Die Bolzen 8 an der Rückenlehne 2, welche nicht mit einer Verbindungsstange verbunden werden, werden in eine Bohrung links und rechts im Rahmen der Rückenlehne 2 gesteckt und dort lösbar gegen Herausfallen gesichert. Je nach Werkstoff der Lehne kann es notwendig werden, je eine (nicht gezeichnete) Lagerbuchse zusätzlich in die Lehne einzubringen. Die Armlehnen 3 mit den daran befindlichen Bolzen 7, 8 werden vorteilhafterweise von aussen aufgesteckt. Auch mit dem Verbindungsrohr 6 werden sie vorteilhafterweise lösbar verbunden. Geeignete lösbare Verbindungen sind z. B. Spannstifte, Schrauben, Sicherungsscheiben, Sicherungsringe u. dgl., wodurch ein Herausfallen verhindert wird. Da die Steckverbindung an sich die senkrecht wirkenden Armlehnenkräfte aufnimmt, werden an die Verbindung keine grossen Festigkeitsansprüche gestellt. Eine besondere Sicherung an der Kulissenführung 9 kann dann mit Vorteil entfallen. Durch die starre Verbindung über die Stange 6 sichern sich die Armlehnen 3a, 3b wechselseitig.The bolts 8 on the backrest 2, which are not connected to a connecting rod, are inserted into a hole on the left and right in the frame of the backrest 2 and are releasably secured there against falling out. Depending on the backrest material, it may be necessary to additionally insert a bearing bush (not shown) into the backrest. The armrests 3 with the bolts 7, 8 located thereon are advantageously attached from the outside. They are also advantageously releasably connected to the connecting tube 6. Suitable detachable connections are e.g. B. dowel pins, screws, locking washers, locking rings and. Like., whereby a falling out is prevented. Since the plug-in connection absorbs the armrest forces acting vertically, no great strength requirements are imposed on the connection. A special securing on the link guide 9 can then advantageously be omitted. The armrests 3a, 3b are mutually secured by the rigid connection via the rod 6.

Fig. 3 zeigt Armlehnenausführungen, welche durch ihre Gestaltung die Kulisse abdecken. Hierzu weisen die vorderen Stützteile 15 der Armlehnen 3 Basisteile 16 auf, die sich über den Längsschlitz der Kulissenführung 9 erstrecken. In dem dargestellten Beispiel befindet sich die Rückenlehne 2 in ihrer vordersten Stellung. Der Abstand 12 zwischen dem Lager 5 und dem hinteren Rand des Basisteils 16 wird mindestens so gross wie der Schlitz in der Kulisse 9 gewählt. Der gleiche Abstand wird vorteilhafterweise auch zum vorderen Rand des Basisteils gewählt.Fig. 3 shows armrest designs, which cover the backdrop by their design. For this purpose, the front support parts 15 of the armrests 3 have base parts 16, which extend over the longitudinal slot of the link guide 9. In the example shown, the backrest 2 is in its foremost position. The distance 12 between the bearing 5 and the rear edge of the base part 16 is chosen to be at least as large as the slot in the link 9. The same distance is advantageously chosen from the front edge of the base part.

Gestrichelt ist in Fig. 3 auch eine Ringlehne dargestellt, mit welcher die Abdeckung des Schlitzes der Kulissenführung 9 besonders erfolgreich bewirkt wird.A ring back is also shown in broken lines in FIG. 3, with which the covering of the slot of the link guide 9 is effected particularly successfully.

Wie bereits erwähnt, können zwei Verbindungsstangen 6 oder auch nur eine verwendet werden. Sie können je nach den Gegebenheiten des Sitzmöbels die korrespondierenden Lager der Rückenlehne 2 und/oder des Sitzes 1 verbinden. Wird nur eine Verbindungsstange 6 verwendet, dann können entweder die kulissengeführten Bolzen oder die anderen, in Bohrungen geführten Bolzen miteinander verbunden werden.As already mentioned, two connecting rods 6 or only one can be used. You can connect the corresponding bearings of the backrest 2 and / or the seat 1 depending on the conditions of the seating. If only one connecting rod 6 is used, then either the link-guided bolts or the other bolts guided in bores can be connected to one another.

Es ist auch eine Lösung möglich, bei welcher zwei Bolzen eingespart werden. Dabei ist in der Rückenlehne 2 pro Armlehne ein Lagerbolzen fest eingebracht. Im Sitz wird die Verbindungsstange 6 soweit verlängert, dass sie rechts und links in die Armlehnen 3a und 3b hineinragt. Die Armlehnen besitzen ihrerseits entsprechende Aufnahmebohrungen, in welche dann die Verbindungsstange 6 eingeschoben und gegen Herausfallen entsprechend gesichert wird.A solution is also possible in which two bolts are saved. A bearing pin is firmly inserted in the backrest 2 per armrest. In the seat, the connecting rod 6 is extended so far that it projects right and left into the armrests 3a and 3b. The armrests in turn have corresponding receiving bores into which the connecting rod 6 is then inserted and appropriately secured against falling out.

Falls es die konstruktiven Belange erfordern, können die Verbindungsstangen 6 auch abgebogen oder abgekröpft werden.If the structural requirements so require, the connecting rods 6 can also be bent or bent.
