Description

Die Erfindung betrifft das Gebiet der Sitzmöbel, insbesondere einen Stuhl mit verstellbarer Sitztiefe, vorzugsweise für den Bürobereich.The invention relates to the field of seating, in particular a chair with adjustable seat depth, preferably for the office area.

STAND DER TECHNIKSTATE OF THE ART

Es sind unterschiedliche technische Lösungen für Stühle bekannt, mittels derer der Benutzer die Sitztiefe, das heißt den horizentalen Abstand des Sitzes zur Lehne, an seine Bedürfnisse anpassen kann.There are different technical solutions for chairs known by means of which the user the seat depth, that is the horizentalen distance of the seat to Lean, can adapt to his needs.

So ist zum Beispiel aus DE 100 48 898 A1 ein Stuhl bekannt, bei welchem der Sitz aus einer starren Sitztragplatte und einer verformbaren Sitzpolsterplatte besteht, die einen Flexbereich aufweist und auf der Sitztragplatte verschoben werden kann. Die Sitzpolsterplatte besteht aus Kunststoff und ist in ihrem Flexbereich aufgrund einer speziellen unterbrochenen Kontur besonders stark verformbar.For example, DE 100 48 898 A1 discloses a chair in which the Seat made of a rigid seat support plate and a deformable seat cushion plate exists, which has a flex area and moved on the seat support plate can be. The seat cushion plate is made of plastic and is in her Flex area due to a special broken contour particularly strong deformable.

Obwohl sich diese Lösung im Prinzip bewährt hat, ist sie in der Herstellung doch noch zu aufwendig, und auch die Gleiteigenschaft der Sitzpolsterplatte auf der Sitztragplatte ist noch verbesserungsfähig. Although this solution has proven itself in principle, it is still in production still too expensive, and also the sliding property of the seat cushion plate on the Seat support plate is still capable of improvement.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist daher die Aufgabe der Erfindung, einen Stuhl mit verstellbarer Sitztiefe derart weiterzuentwickeln, dass er einfach und damit kostengünstig herstell- und montierbar ist, aber dennoch hinsichtlich der Sitztiefenverstellung dem Benutzer optimalen Sitzkomfort bietet.It is therefore the object of the invention to provide a chair with adjustable seat depth to develop such that it is simple and therefore inexpensive to manufacture and can be mounted, but still with regard to the seat depth adjustment the user offers optimal seating comfort.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst.This object is achieved by the features of claim 1 and the Subclaims solved.

Der Kern der Erfindung ist die Idee, die Tragplatte und die Sitzplatte in Konstruktion, Form und Material so aufeinander abzustimmen, dass sie mit wenigen Mitteln und in einfacher Weise montierbar sind, im Gebrauch dann aber dennoch optimal aufeinander gleiten. Besonders vorteilhaft ist in diesem Sinne die Ausbildung der Tragplatte als Rahmen aus Aluminium-Druckguss, und der Sitzplatte als einheitliches Kunststoff-Teil, vorzugsweise aus Polypropylen, mit einer Dicke von etwa 5 mm im Hauptteil, und einer Dicke von etwa 1,5 mm in den Führungsbahnen und Quernuten.The essence of the invention is the idea of the support plate and the seat plate in Design, shape and material to coordinate with each other few resources and are easy to assemble, but then in use nevertheless glide optimally on each other. It is particularly advantageous in this sense the formation of the support plate as a frame of die-cast aluminum, and the Seat plate as a single plastic part, preferably made of polypropylene, with a thickness of about 5 mm in the main part, and a thickness of about 1.5 mm in the guideways and transverse grooves.
