Der in Fig. 1 dargestellte Stuhl weist einen Sitz 1 auf, der über symmetrisch
zueinander angeordnete Stuhlbeine 2, 3 mit Stuhlrollen 4 auf dem
Boden abgestützt ist. Die Stuhlbeine 2, 3 sind jeweils paarweise zu einer
Armlehne 5 zusammengefaßt. An den hinteren Enden der Armlehnen 5 ist
eine Rückenlehne 6 angebracht, die einen rechteckigen, und insbesondere
quadratischen Rückenlehnen-Rahmen 7 aufweist, der mit einem Bezug 8
versehen ist.The chair shown in Fig. 1 has a
Wie sich aus Fig. 2 ergibt, besteht der Rahmen 7 aus zwei etwa gleichen C-förmigen
Rahmenteilen 9, 10. Sie bestehen aus Metall-Rohren 11, die an
den Ecken 12 zwischen jeweils einem Schenkel 13 bzw. 14 und einem Steg
15 durch Verschweißen miteinander verbunden sind. Die beiden Rahmenteile
9, 10 werden - wie sich aus der Explosionsdarstellung in Fig. 2 ergibt
- an den freien Enden ihrer Schenkel 13, 14 miteinander verbunden. Zur
Zentrierung ist an einem Ende eines Schenkels 13 bzw. 14 ein Zentrierzapfen
16 angebracht, der in das zugeordnete Ende des mit ihm fluchtenden
Schenkels 13 bzw. 14 eingeführt wird. As is apparent from Fig. 2, the
Der durch die beiden Rahmenteile 9, 10 zu bildende Rahmen 7 wird mit
dem in Fig. 3 dargestellten Bezug 8 versehen. Dieser weist an seinen vier,
den Stegen 15 und den Schenkeln 13, 14 zugeordneten Längsseiten jeweils
einen hohlen Kedersaum 17, 18, 19, 20, also einen schlauchförmigen Hohlsaum
auf. Der Bezug 8 besteht aus einer Strickware aus Natur- und/oder
Kunststoff- und/oder Metall-Garn oder einer geeigneten Mischung aus solchen
Garnen. Er kann auch aus einem ausreichend elastischen Gewebe
hergestellt werden. Die Kedersäume 17 bis 20 können beim Stricken mit

die insbesondere auch in Fig. 4 dargestellt sind. Diese auch einen Teil der
Rückenlehne 6 bildenden Verbindungselemente 22 sind T-förmig ausgebildet.
Ihr vertikal anzuordnender End-Steg 23 weist eine der Krümmung
der Rohre 11 angepaßte Innenfläche 24 auf. Er ist weiterhin mit zwei Bohrungen
25 versehen, die mit zwei Bohrungen 26 in den Schenkeln 13, 14
der Rahmenteile 9, 10 fluchten, wenn letztere in der geschilderten Weise
miteinander auf Stoß verbunden sind. Durch die Bohrungen 25 werden
Schrauben 27 in die Bohrungen 26 geschraubt. Hierdurch werden die beiden
Rahmenteile 9, 10 fest miteinander und mit den Verbindungselementen
21 verbunden. Des weiteren deckt der End-Steg 23 jedes Verbindungselements
22 die zugeordnete Öffnung 21 im Kedersaum 17, 19 des Bezuges 8
ab, so daß die Öffnung 9 von außen unsichtbar wird.Connecting the backrest pre-assembled in the manner described

Der jeweilige Mittel-Steg 28 jedes Verbindungselements 22 weist zwei
parallel zueinander vorspringende Haltezapfen 29, 30 auf, die in die beiden
offenen Enden der die Stuhlbeine 2, 3 bildenden und zu einer Armlehne 5
zusammengefaßten Rohre 31, 32 eingeführt werden. Eine Fixierung der
Verbindungselemente 22 mit den Rohren 31, 32 erfolgt mit jeweils einer
Schraube 33, die von unten durch das jeweils außenliegende Rohr 31 in
eine Bohrung 34 im längeren Haltezapfen 29 geschraubt wird. Von dieser
Verbindung werden die vom Benutzer des Stuhls auf die Rückenlehne 6
ausgeübten Anlehnkräfte aufgenommen.The respective
Der Rückenlehnen-Rahmen 7 ist gebogen ausgebildet, d. h. die horizontalen
Stege 15 sind - vom Sitz 1 her gesehen - nach hinten durchgebogen,
während die vertikalen Schenkel 13, 14 zum Sitz 1 hin durchgebogen sind.The
Bei dem in Fig. 5 dargestellten Stuhl handelt es sich um einen Bürostuhl,
dessen Sitz 40 auf einem nicht dargestellten Sitzträger befestigt ist, der mittels
einer längenverstellbaren Stuhlsäule 41 auf einem Fußkreuz 42 angebracht
ist, das sich wiederum über Stuhlrollen 43 auf dem Boden abstützt.
An dem Sitz tragenden Sitzträger ist ein Rückenlehnen-Träger 44 angebracht,
der hinter dem Sitz 40 nach oben ragt. Er ist kreuzförmig ausgebildet,
d. h. er weist einen im wesentlichen vertikal nach oben ragenden Mittel-Stab
45 und einen im wesentlichen horizontal verlaufenden Quer-Stab
46 auf. Beide Stäbe 45, 46 sind zu ihren Enden hin in Richtung zum Sitz 40
gebogen, d. h. sie sind vom Sitz 40 her gesehen konkav ausgebildet bzw.
von der Rückseite her gesehen konvex ausgebildet.The chair shown in FIG. 5 is an office chair,

Am Rückenlehnen-Träger 44 ist Teil einer Rückenlehne 47 befestigt, die -
wie beim zuvor geschilderten Ausführungsbeispiel - einen etwa rechteckigen,
insbesondere etwa quadratischen Rückenlehnen-Rahmen 48 aufweist,
der mit einem Bezug 49 versehen ist, der in gleicher Weise ausgebildet ist,
wie der zuvor geschilderte, in Fig. 3 dargestellte Bezug 8, so daß auf die
zugehörige Beschreibung verwiesen werden kann.Part of a
Der Rahmen 48 besteht ebenfalls aus zwei C-förmigen Rahmenteilen 50,
51, deren Schenkel 52, 53 in diesem Ausführungsbeispiel horizontal angeordnet
sind, während die Stege 54 vertikal angeordnet werden. Die Schenkel
52, 53 weisen an ihren freien einander zugewandten Enden Flansch-Stege
55, 56 auf, die jeweils paarweise miteinander in Überdeckung gebracht
werden und dann den gleichen Querschnitt haben, wie die Schenkel
52, 53. Sie weisen jeweils zwei Bohrungen 57 auf, die beim Übereinanderliegen
der Stege 55, 56 miteinander fluchten und die mit Bohrungen 58 in
Überdeckung gebracht werden können, die in Auflagern 59, 60 des Mittel-Stabes
45 ausgebildet sind. In den Enden des Quer-Stabes 46 sind ebenfalls
Bohrungen 61 ausgebildet, die beim Anliegen des Rahmens 48 am Rückenlehnen-Träger
44 mit jeweils einer Bohrung 62 in der Mitte des jeweiligen
Steges 54 fluchten.The
Die Rahmenteile 50, 51 sind bei diesem Ausführungsbeispiel nicht aus Metall-Rohren
gebildet, sondern bestehen aus gespritztem faserverstärktem
Kunststoff, beispielsweise mit Graphitfasern verstärktem Kunststoff. The
Die Montage erfolgt in der Weise, daß - wie bereits geschildert - zuerst ein
Schenkel 52 und dann der Steg 54 und dann der andere Schenkel 53 eines
Rahmenteils 50 bzw. 51 durch eine Einführ-Öffnung 21 des Bezuges 49 in
die Kedersäume 17, 18, 19 und anschließend das andere Rahmenteil 51 in
gleicher Weise in die Kedersäume 17, 20, 19 geschoben wird. Auch hier
sind die Kedersäume 17 bis 20 breiter als die Schenkel 52, 53 und die Stege
54, um das Einschieben zu ermöglichen. Die Flansch-Stege 54, 55 befinden
sich anschließend in Überdeckung mit den Öffnungen 21 des Bezuges
49. Zur Montageerleichterung werden die Rahmenteile 50, 51 dadurch
gegeneinander stabilisiert, daß ein nicht dargestellter Montagehilfsstift
durch mittlere Zentrierbohrungen 63 der Flansch-Stege 55, 56 geschoben
wird. Anschließend wird die auf diese Weise vormontierte Rückenlehne 47
an die als Verbindungselemente dienenden Auflager 59, 60 angelegt, woraufhin
die Befestigung des Rahmens 48 mit Bezug 49 am Mittel-Stab 45
dadurch erfolgt, daß Schrauben 64 durch die Bohrungen 58 in den Auflagern
59, 60 in die Bohrungen 57 der aufeinander liegenden Flansch-Stege
55, 56 geschraubt werden, wodurch gleichzeitig auch eine feste Verbindung
der Rahmenteile 50, 51 miteinander erreicht wird. Zur Stabilisierung
der Rückenlehne 47 werden dann noch Schrauben 65 durch die Bohrungen
61 im Quer-Stab 46 in die Bohrungen 62 in den Stegen 54 geschraubt.The assembly takes place in such a way that - as already described -
Auch bei dieser Ausgestaltung werden die Öffnungen 21 des Bezuges 49
vollständig durch die Auflager 59, 60 abgedeckt, so daß sie unsichtbar
werden. Die Schrauben 65 werden durch den Bezug 49 hindurchgeschraubt;
für sie müssen keine Öffnungen im Bezug vorgesehen werden.
Auch beim Ausführungsbeispiel nach den Fig. 5 und 6 kann der Rückenlehnen-Rahmen
48 insgesamt gebogen ausgebildet sein, d. h. die horizontalen
Schenkel 52, 53 sind nach hinten zum Rückenlehnen-Träger 44 hin
durchgebogen, während die vertikalen Stege 54 zum Sitz 40 hin durchgebogen
sind.In this embodiment, too, the
