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.

Bei einem bekannten Sitzmöbel dieser Art (EU-A-0 005 556) ist der Armauflagebereich am oberen Ende des Armlehnenträgers schwenkbar angelenkt. Der Armauflagebereich kann in jeder Verschwenkposition gegenüber dem Armlehnenträger mit Hilfe einer Klemmverbindung fixiert werden. Der Armlehnenträger ist an seinem unteren Ende in einer Gleitführung befestigt, welche so ausgebildet ist, dass sie nicht nur ein Verschieben des Armlehnenträgers in Längsrichtung ermöglicht sondern auch dessen Verschwenken um eine vertikale Achse. Dabei ist der Armlehnenträger in jeder Verschwenklage mit Hilfe einer Klemmverbindung fixierbar.In a known seating of this type (EU-A-0 005 556), the armrest area is pivotably articulated at the upper end of the armrest support. The armrest area can be fixed in any pivot position relative to the armrest support with the help of a clamp connection. The armrest support is fastened at its lower end in a slide guide which is designed such that it not only enables the armrest support to be displaced in the longitudinal direction but also to pivot it about a vertical axis. The armrest support can be fixed in any pivot position using a clamp connection.

Bei dem bekannten Sitzmöbel sind die Verstellmöglichkeiten der Armlehnen unbegrenzt. Dies ist nur auf den ersten Blick sinnvoll. Tatsächlich überfordert die Vielzahl der Auswahlmöglichkeiten nahezu alle Stuhlbenutzer. Mit der Vielzahl der Verstellmöglichkeiten wächst die Gefahr einer eventuell unbemerkten Falscheinstellung. So kann eine Einstellung auch dann falsch sein, wenn sie dem Benutzer zunächst bequem vorkommt, tatsächlich jedoch Sitzfehler zur Folge hat, die zu Rückenschmerzen oder dergleichen führen und deren Ursache vom Benutzer nicht in der objektiv falschen Einstellung der Armlehne gesucht wird.In the known seating furniture, the adjustment options for the armrests are unlimited. This only makes sense at first glance. In fact, the multitude of choices overwhelms almost all chair users. With the multitude of adjustment options, the risk of a possibly unnoticed incorrect setting increases. A setting can also be wrong if it initially seems comfortable to the user, but actually results in seat errors that lead to back pain or the like and the cause of which is not sought by the user in the objectively incorrect setting of the armrest.

Höhenverstellbare Armlehnen, in denen eine Gleitführung vorgesehen ist, sind aus der US-A-3434756 bekannt. Bei diesen bekannten Armlehnen verläuft die Gleitführung unter 90° zum Armauflagebereich. Dies hat zur Folge, dass nicht der Abstand der Armlehne von der vorderen Kante des Sitzes einstellbar ist.Height-adjustable armrests, in which a sliding guide is provided, are known from US-A-3434756. In these known armrests, the sliding guide runs at 90 ° to the armrest area. As a result, the distance between the armrest and the front edge of the seat cannot be adjusted.

Ausgehend von dem eingangs erwähnten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Sitzmöbel mit höhenverstellbarer Armlehne der bekannten Art so auszubilden, dass in einfacher Weise eine Verstellung des Armauflagebereichs nach vorn oder nach hinten möglich ist.Based on the prior art mentioned at the outset, the object of the invention is to design a piece of seating furniture with a height-adjustable armrest of the known type in such a way that the arm support area can be adjusted in a simple manner to the front or to the rear.

Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Kennzeichnungsteils von Anspruch 1.This object is achieved with the features of the labeling part of claim 1.

Bei einer bevorzugten Ausführungsform, bei der zwischen Armlehnenträger und Armlehne ein Feststellmechanismus für das Arretieren der Armlehne in unterschiedlicher Höhenlage vorgesehen ist, ist der Feststellmechanismus als Rastmechanismus ausgebildet. Bevorzugte weitere Ausgestaltungen der Erfindung sind in den weiteren Unteransprüchen beschrieben.In a preferred embodiment, in which a locking mechanism for locking the armrest at different heights is provided between the armrest support and the armrest, the locking mechanism is designed as a locking mechanism. Preferred further developments of the invention are described in the further subclaims.

Ein Armlehnenträger 1 ist mit dem Sitzträger oder dem Sitz verbunden. Der Armlehnenträger 1 ragt in eine Armlehne 2, die eine Gleitführung 2a aufweist. Mit 3 ist der Armauflagebereich bezeichnet. Der Abstand der Vorderkante des Armauflagebereichs 3 von der Längsmittelebene 11 des Armlehnenträgers 1 ist mit a bezeichnet, der Abstand von der Längsmittelebene 11 zur hinteren Kante des Armauflagebereichs mit b. Im dargestellten Ausführungsbeispiel ist b grösser als a.An armrest support 1 is connected to the seat support or the seat. The armrest support 1 projects into an armrest 2 which has a slide guide 2a. The arm support area is designated by 3. The distance of the front edge of the armrest area 3 from the longitudinal center plane 11 of the armrest support 1 is denoted by a, the distance from the longitudinal center plane 11 to the rear edge of the armrest area is b. In the illustrated embodiment, b is greater than a.

Die Längsmittelebene 11 schliesst mit der Armauflage einen Winkel a bzw. β ein und verläuft nicht senkrecht zum Armauflagebereich.The longitudinal center plane 11 forms an angle a or β with the armrest and is not perpendicular to the armrest area.

Der Armlehnenträger 1 kann entweder mit einer Schrägneigung nach vorn unter dem Winkel 9 (siehe Figur 1) oder mit einer Schrägneigung nach hinten y (siehe Figur 2) montiert werden. Je nach Montageart ist der Abstand der Vorderkante des Armauflagebereichs 3 von der vorderen Sitzkante kleiner (x in Figur 1) oder grösser (y in Figur 2).The armrest support 1 can either be mounted with an inclination to the front at an angle 9 (see FIG. 1) or with an inclination to the rear y (see FIG. 2). Depending on the type of installation, the distance between the front edge of the armrest area 3 and the front seat edge is smaller (x in FIG. 1) or larger (y in FIG. 2).
