Abstract

The dynamic back rest is basically rigid with leaf or helical springs mounted so that they are convexly curved towards the back and automatically move to support the spinal column no matter what sitting position is occupied. The radius of curvature of the springs can be adapted to the individual requirements by mechanical aids. The leaf springs can be made of metal and/or other resilient materials and can be connected together underneath by webs wherein a standard foam or padded upholstery cover can then be applied. Additional suspension elements can be mounted between the springs and the rigid back rest, for example air cushions or resilient filling material.

Description

Dynamische Sitzlehne Schäden an der Wirbelsäule, besonders Verformungen der Bandscheiben, werden besonders heufig durch Haltungsfehler in der sitzenden Position verursacht. Das gilt für alle Sitzgelegenheiten in gleichem Maß und besonders, wenn eine einmal eingenommene Haltung über längere Zeit beibehalten wird, Die einseitige Belastung der Bandscheiben führt zu deren keilförmiger Verformung. olgen sind, Schmerz, Beschädigungen bis zum Ausscheren, Auch die "Schmierung" zwischen den Wirbelkörpern, die nur durch häufige Positionsänderung gewährleistet ist, bleibt aus.Dynamic seat back damage to the spine, especially deformation of the intervertebral discs, are particularly common due to poor posture in the sitting position Position caused. This applies equally to all seating and especially, if a posture once taken is maintained over a long period of time, the one-sided Load on the intervertebral discs leads to their wedge-shaped deformation. olgen are, pain, Damage up to the shear, also the "lubrication" between the vertebral bodies, which is only guaranteed by frequent changes of position, does not occur.

Zwar bemüht man sich um optimale Formgebung von Sitzgelegenheiten, die auch durch mechanische Verstellmöglichkeiten die individuellen Maße nach Größe und Krümmungsradien mit Beiwirkung spezieller Polster korrigieren helfen; eine optimale Anpassung wird aber kaum erreicht, weil die häufige Betätigung von Bedienungselementen zu unbequem ist und/oder diese nicht hinreichend genutzt oder verstanden werden.Although efforts are made to optimally shape seating, The individual dimensions according to size thanks to mechanical adjustment options and help correct radii of curvature with the help of special pads; an optimal one Adaptation is hardly achieved, however, because of the frequent actuation of control elements is too inconvenient and / or not used or understood adequately.

Der Gegenstand der Erfindung geht von einer starren Lelfrenkonstruktion aus, die eingebaut oder aufgesetzt werden kann. Auf der Lehne sind Federblätter, konvex gegen den Rücken vorgespannt, befestigt.The object of the invention is based on a rigid Lelfrenkonstruktion that can be built in or attached. On the back are feather leaves, convexly biased against the back, fastened.

Der Krümmungsradius kann durch mechanische Hilfsmittel den individuellen Erfordernissen angepaßt werden.The radius of curvature can be adjusted to the individual by mechanical means Needs to be adapted.

Bei Andruck einer Zone der Federn gegen die Lehne müssen diese dort ausweichen, um in einer anderen Region durch engeren Krümmungsradius und dadurch bedingten Vorschub ihre festgelegte Länge zu kompensieren.When a zone of the springs is pressed against the backrest, they must be there dodge to another region by tighter radius of curvature and thereby conditional feed to compensate for their specified length.

In Abb.1 sind Beispiele für die Wirkungsweise in verschiedenen Sitzpositionen gezeigt. Diese wird einfach dadurch realisiert, daß man auf dem Sitz vor- oder zurückrutscht und/oder den Oberkörper vor- oder zurücklehnt.Figure 1 shows examples of how it works in different sitting positions shown. This is done simply by sliding forwards or backwards on the seat and / or lean the upper body forward or backward.

Eine tberkleidung der Federn in iiblicher Art mit Schaumstoff und Textilien oder anderen Materialien ist wahlweise aufzubringen0 (Eine klinische Anwendung bei bereits manifestierten Erkrankungen der Wirbelsäule, z.B Lordose, Skoliose o.Ä. ist in Erwägung gezogen. Bei Lumbago (Hexenschuß) ist im Vorversuch eine deutliche Linderung der Beschwerden festgeste31t worden Es versteht sich, dao diese Art der Anwendung ärztlicher Indikation belassen bleibt).A covering of the feathers in the usual way with foam and Textiles or other materials can be applied optionally0 (A clinical application in the case of diseases of the spine that have already manifested themselves, e.g. lordosis, scoliosis, etc. is being considered. In the case of lumbago (lumbago) there is a clear one in the preliminary experiment Relief of discomfort has been noted. It goes without saying that this kind of Application of medical indication remains).
