Abstract

A bent spring plate (1) is used, the width of which is two thirds of that of the chair seat, and connects the seat (2) and the backrest (3). It is fitted with an intermediary cushion. A swivel stirrup which is bent is fixed to the back rest, and extends to beneath the seat where it is articulatedly connected to the foot frame. The seat is elastically fitted under its front and rear edges to the foot frame (4) and the swivel stirrup. USE/ADVANTAGE - To increase comfort in an office swivel chair by allowing the seat and backrest to move synchronously.

Description

Sitz und Lehne sind im einfachsten Fall aus Sperrholz-Formteilen. Bei der Erfindung verbindet ein Federblech von 2/3 Sitzbreite mit großem Biegeradius Sitz und Lehne. Dies geschieht beispiels­ weise in bekannter Weise durch Nietung.In the simplest case, the seat and backrest are made of molded plywood. In the invention, a spring plate of 2/3 seat width connects with large bending radius seat and backrest. This happens for example wise in a known manner by riveting.

Das Federblech erlaubt 1. das Zurückfedern der Lehne gegenüber dem Sitz, dient 2. als Federunterstützung und 3. als Träger für ein Zwischenpolster zwischen Sitz und Lehne.The spring plate 1. allows the backrest to spring back the seat, 2. serves as a spring support and 3. as a support for an intermediate cushion between seat and backrest.

Das Zwischenpolster folgt der Bewegung des Federbleches. Es schließt in vorteilhafter Weise die Lücke zwischen Sitz und Lehne.The intermediate cushion follows the movement of the spring plate. It advantageously closes the gap between the seat and Rest.

An der Rückseite der Lehne ist in an sich bekannter Weise ein Schwenkbügel befestigt, der aber bis unter den Sitz reicht und am Fußgestell des Stuhles gelenkig gelagert ist.On the back of the back is in a manner known per se Swivel bracket attached, but which extends below the seat and is articulated on the base of the chair.

Der Sitz ist in an sich bekannter Weise unter der Vorderkante mit Gummilagern auf dem Fußgestell flexibel gelagert.The seat is under the front edge in a manner known per se flexibly mounted with rubber bearings on the base.

An der Hinterkante liegt er mit Gummilager auf dem Schwenkbügel auf.At the rear edge it lies with a rubber bearing on the swivel bracket on.

Diese Anordnung ersetzt die heute übliche Verstellmechanik der Lehne, ohne teurer in der Herstellung zu sein. Sie erlaubt die federgestützte Synchronbewegung von Sitz und Lehne im Winkel­ verhältnis 1 : 2.This arrangement replaces the adjustment mechanism common today Lean back without being more expensive to manufacture. It allows that spring-supported synchronous movement of seat and backrest at an angle ratio 1: 2.
