Abstract

The invention relates to a seat, comprising a seat base (2), mounted on a support frame (4), by means of seat mechanisms and a backrest (3), arranged over the rear section of the above, whereby both seat base and/or backrest may be pushed back and forth. A flexible adjustment of the seating surface is thus achieved, whereby the seat base (2) and the backrest (3) may be displaced relative to each other, with the rear section of the seat base (2) able to extend through or beneath the backrest (3), which may be moved backwards.

Description

S i t zSeat
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 und/oder die Rückenlehne vor und zurück verschiebbar sind.The invention relates to a seat with a seat part mounted on a support frame with seat mechanism and a backrest arranged above the rear section thereof, the seat part and / or the backrest being displaceable back and forth.
Bei bisher bekannten Schiebesitzen wird die Position des Sitzteils über feststehenden Elementen eines Tragegestelles, beispielsweise einem Standrohr, verschoben, wobei die Sitzfläche gleich groß bleibt. Dabei kann auch der Abstand zur Rückenlehne verändert werden.In previously known sliding seats, the position of the seat part is shifted over fixed elements of a support frame, for example a standpipe, the seat area remaining the same size. The distance to the backrest can also be changed.
Der Erfindung liegt die Aufgabe zugrunde, einen Sitz der eingangs genannten Art zu schaffen, bei dem die Anpassung an einen Benutzer flexibler ist. Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Hiernach ist vorgesehen, dass der Sitzteil und die Rückenlehne relativ zueinander verschiebbar sind, wobei der hintere Abschnitt des Sitzteils durch die oder unter der Rückenlehne hindurch und diese nach hinten überragend verlagerbar ist.The invention has for its object to provide a seat of the type mentioned, in which the adaptation to a user is more flexible. This object is achieved with the features of claim 1. According to this, it is provided that the seat part and the backrest can be displaced relative to one another, the rear section of the seat part being able to be displaced through or under the backrest and projecting beyond it to the rear.
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.With the relative movement between the seat part and the backrest part forwards and backwards, with the rear section of the seat part passing through (or undermining) the backrest surface, the effective size of the seat surface between the backrest and the front edge of the seat part changes. As a result, the size of the seat surface can be adapted to users of different sizes or different seating situations, with a continuous seat surface up to the backrest being always retained.
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 is mounted displaceably and lockable on the seat mechanism, while the seat part is fixed on the support frame is.
Dabei wird der Sitzkomfort dadurch unterstützt, dass am Sitzteil der Sitzfläche zugekehrte Beckenrandstützen angeordnet sind, die während des Verschiebens des Sitzteils in dem Sitzbereich nahe dem benachbarten unteren Rückenlehnenabschnitt gehalten sind.The seating comfort is supported by the fact that on the seat part of the seat surface facing pool edge supports are arranged, which are held in the seating area near the adjacent lower backrest section during the displacement of the seat part.
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 consist in the fact that the pelvic edge supports are fixed in place with respect to the support frame when the seat part is displaceable are, while they are fixed with respect to the movable backrest.
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 in that coupling pieces between the support frame and the pool edge supports are guided through slots running in a base part of the seat part in the sliding direction. The contour of the seat is further improved in that the seat part has an upholstery on its upper side and that the pool edge supports under the upholstery under a sliding surface e.g. are made of leather or suitable plastic material. The side of the pool edge supports facing the base part is also designed to slide smoothly.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert.The invention is explained in more detail below using an exemplary embodiment with reference to 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 Fig. Shows a section of a seat 1, in particular an office chair with its essential parts here, seat part 2, backrest 3 and support frame 4 with seat mechanism in cross section. The seat part 2 is provided on a bowl-shaped base part 2.2 with a padding 2.1.
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 vor- geschobenen 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 seat part 2 can be moved back and forth relative to the support frame 4 and can be locked in a desired position. The rear section of the seat part 2 pierces the backrest 3 in its lower section or, depending on the connection thereof to the support frame 4 or the seat mechanism, runs under the backrest 3. Both in the most advanced pushed as well as the most retracted position remains a continuous seat between the front edge of the seat part 2 and the lower portion of the backrest 3.
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, a favorable contour of the seat surface is maintained by means of contour elements provided under the padding 2.1. In the present case, contour elements are arranged laterally above the base part 2.2 in the area of the seat near the lower section of the backrest 3, which are guided by means of coupling pieces 5.1 in the form of two screw domes through slots provided in the base part 2.2 and extending in the direction of displacement and with the support frame 4 or the seat mechanism are connected. When the seat part 2 is moved, the pelvic edge supports 5 remain in a fixed position with respect to the support frame 4 and thus move relative to the seat part 2 under the upholstery 2.1. For this purpose, a suitable sliding guide for the pool edge supports 5 is formed between the upholstery 2.1 and the upper side of the base part 2.2.
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 seat part 2, it can also be held relative to the support frame 4 on the seat mechanism and instead the backrest 3 can be displaceably mounted on the seat mechanism. A displaceable mounting of both the seat part 2 and the backrest 3 on the seat mechanism of the support frame 4 is also conceivable, e.g. the seat part 2 and the backrest 3 are moved when moving in opposite directions.
