Description
Die Erfindung bezieht sich auf einen Sitz mit einem auf einem Tragegestell mit Sitzmechanik gelagerten Sitzteil und einer über dessen hinterem Abschnitt angeordneten Rückenlehne, wobei der Sitzteil oder die Rückenlehne in der Weise vor und zurück verschiebbar sind, dass der Sitzteil und die Rückenlehne relativ zueinander verschiebbar sind und der hintere Abschnitt des Sitzteils durch die oder unter der Rückenlehne hindurch und diese nach hinten überragend verlagerbar ist.The invention relates to a seat with a on a support frame Seat mechanism mounted seat part and one arranged above its rear section Backrest, with the seat part or the backrest in the Way back and forth are that the seat part and the backrest are displaceable relative to each other and the rear portion of the seat part through or under the backrest and protruding backwards is relocatable.
Ein derartiger Sitz ist in der US-A-3,511,533 angegeben. Bei diesem bekannten Sitz ist ein Sitzteil mit seinem hinteren Abschnitt unter der Unterseite einer Rückenlehne hindurch verschiebbar.Such a seat is given in US-A-3,511,533. In this well-known Seat is a seat part with its rear section under the bottom of one Backrest can be moved through.
In der EP-A-0 970 637, der WO-A-99/44473 und der US-A-6,027,168 sind weitere Sitze gezeigt, bei denen ein Sitzteil relativ zu der Rückenlehne vor- und zurückschiebbar gelagert sind. In EP-A-0 970 637, WO-A-99/44473 and US-A-6,027,168 further seats shown, in which a seat part in front of and relative to the backrest are retractable.
Der Erfindung liegt die Aufgabe zugrunde, einen Sitz der eingangs genannten Art zu schaffen, bei dem die Anpassung an einen Benutzer flexibler ist.The invention has for its object a seat of the aforementioned To create ways in which the adaptation to a user is more flexible.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Hiernach ist
vorgesehen, dass am Sitzteil der Sitzfläche zugekehrte Beckenrandstützen angeordnet
sind, die während des Verschiebens des Sitzteils oder der Rückenlehne in dem Sitzbereich
nahe dem benachbarten unteren Rückenlehnenabschnitt gehalten sind.This object is achieved with the features of
Mit der Relativbewegung zwischen dem Sitzteil und dem Rückenlehnenteil nach vorne und hinten, wobei der hintere Abschnitt des Sitzteils die Rückenlehnenfläche nach hinten durchläuft (bzw. unterläuft), ändert sich die wirksame Größe der Sitzfläche zwischen Rückenlehne und Vorderrand des Sitzteils. Hierdurch wird die Größe der Sitzfläche an unterschiedlich große Benutzer oder unterschiedliche Sitzsituationen anpassbar, wobei stets eine durchgehende Sitzfläche bis zur Rückenlehne erhalten bleibt. Durch die dabei an günstiger Stelle gehaltenen Beckenrandstützen wird der Sitzkomfort unterstützt.With the relative movement between the seat part and the backrest part after front and rear, with the rear section of the seat part the backrest surface runs backwards (or undershoots), the effective size changes the seat between the backrest and the front edge of the seat part. hereby is the size of the seat to different sized users or different Adjustable seating situations, always a continuous seat is preserved up to the backrest. By doing so in a convenient place The comfort of the pelvic supports is supported.
Zwei verschiedene Aufbaumöglichkeiten bestehen dabei darin, dass der Sitzteil in einer Schiebeführung der Sitzmechanik verschiebbar und arretierbar ist, während die Rückenlehne unverschieblich an dem Tragegestell gelagert ist, oder dass die Rückenlehne an der Sitzmechanik verschieblich und arretierbar gelagert ist, während der Sitzteil an dem Tragegestell festgelegt ist.Two different construction options are that the seat part is displaceable and lockable in a sliding guide of the seat mechanism, while the backrest is mounted immovably on the support frame, or that the backrest on the seat mechanism can be moved and locked is while the seat part is fixed to the support frame.
Verschiedene Aufbauweisen bestehen dabei darin, dass die Beckenrandstützen bei verschieblichem Sitzteil ortsfest bezüglich des Tragegestelles angebracht sind, während sie bei verschieblicher Rückenlehne ortsfest bezüglich dieser angebracht sind.Different construction methods are that the pool edge supports with a moveable seat part fixed in place with respect to the support frame are, while they are fixed with respect to the movable backrest are.
Die Anordnung der Beckenrandstützen wird dadurch begünstigt, dass Koppelstücke zwischen dem Tragegestell und den Beckenrandstützen durch in einem Basisteil des Sitzteils in Schieberichtung verlaufende Schlitze geführt sind. Die Sitzkontur wird weiterhin dadurch verbessert, dass der Sitzteil auf seiner Oberseite eine Polsterung aufweist und dass die Beckenrandstützen unter der Polsterung unter einer Gleitfläche z.B. aus Leder oder geeignetem Kunststoffmaterial angeordnet sind. Auch die dem Basisteil zugekehrte Seite der Beckenrandstützen ist gut gleitend ausgebildet.The arrangement of the pool edge supports is favored by the fact that coupling pieces between the support frame and the pool edge supports by in a base part of the seat part are guided in the sliding direction slits. The Seat contour is further improved in that the seat part on its top has an upholstery and that the pool edge supports under the upholstery under a sliding surface e.g. arranged from leather or suitable plastic material are. The side of the pool edge supports facing the base part is also well trained.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert.The invention is described below with reference to an exemplary embodiment explained in more detail on the drawing.
Die Fig. zeigt ausschnittsweise einen Sitz 1, insbesondere einen Bürostuhl mit
seinen hier wesentlichen Teilen, Sitzteil 2, Rückenlehne 3 und Tragegestell 4 mit
Sitzmechanik im Querschnitt. Der Sitzteil 2 ist auf einem schalenförmigen Basisteil
2.2 mit einer Polsterung 2.1 versehen.The figure shows a section of a
An der Sitzmechanik des Tragegestelles 4 ist ein Schiebemechanismus angeordnet.
mit dem der Sitzteil 2 relativ zu dem Tragegestell 4 nach hinten und vorne
verschiebbar und in einer gewünschten Stellung arretierbar ist. Der hintere Abschnitt
des Sitzteils 2 durchstößt dabei die Rückenlehne 3 in ihrem unteren Abschnitt
oder läuft, je nach Anbindung derselben an dem Tragegestell 4 bzw. der
Sitzmechanik, unter der Rückenlehne 3 hindurch. Sowohl in der am weitesten vorgeschobenen
als auch am weitesten zurückgeschobenen Stellung bleibt dabei eine
durchgehende Sitzfläche zwischen dem vorderen Rand des Sitzteils 2 und dem unteren
Abschnitt der Rückenlehne 3 erhalten.A sliding mechanism is arranged on the seat mechanism of the support frame 4.
with which the
Bei der Verschiebung wird mittels unter der Polsterung 2.1 vorgesehener Konturelemente
eine günstige Kontur der Sitzfläche aufrecht erhalten. Vorliegend sind als
Konturelemente in dem Bereich der Sitzfläche nahe dem unteren Abschnitt der
Rückenlehne 3 seitlich Beckenrandstützen 5 über dem Basisteil 2.2 angeordnet,
die mittels Koppelstücken 5.1 in Form zweier Schraubdome durch in dem Basisteil
2.2 vorgesehene, in Verschieberichtung verlaufende Schlitze geführt und mit dem
Tragegestell 4 bzw. der Sitzmechanik verbunden sind. Beim Verschieben des Sitzteils
2 verbleiben die Beckenrandstützen 5 in ortsfester Position bezüglich des
Tragegestelles 4 und verschieben sich damit relativ zu dem Sitzteil 2 unter der
Polsterung 2.1. Zwischen der Polsterung 2.1 und der Oberseite des Basisteils 2.2
ist dazu eine geeignete Gleitführung für die Beckenrandstützen 5 ausgebildet.During the displacement, contour elements provided under the padding 2.1 are used
maintain a favorable contour of the seat. Are present as
Contour elements in the area of the seat near the lower section of the
Alternativ zur Verschiebung des Sitzteils 2 kann dieser relativ zu dem Tragegestell
4 an der Sitzmechanik auch festgehalten und stattdessen die Rückenlehne 3 an
der Sitzmechanik verschieblich gelagert sein. Denkbar ist auch eine verschiebbare
Lagerung sowohl des Sitzteils 2 als auch der Rückenlehne 3 an der Sitzmechanik
des Tragegestelles 4, wobei z.B. der Sitzteil 2 und die Rückenlehne 3 beim Verschieben
in entgegen gesetzte Richtungen bewegt werden.As an alternative to moving the
