Abstract

The seat back cushion is provided with a shaped recess into which is fitted a special support cushion supported on the rest of the seat on a special moulded shell. The surface of the cushion is covered with a loose cover which enables the friction between the occupants back and the cushion to be substantially reduced. The cushion therefore gives support without transmitting vertical vibrations to the occupant, and greatly reduces back strain, and even back injury. The cushion can be of rubber type material or a material loop stretched between two rollers.

Description

Schwingpolster für Autositzlehne Beschreibung Gegenstand der Erfindung ist ein Schwingpolster für Autositzlehne,mit dem die vielfältigen,kleinen und größeren Schwingungen,die der Autofahrer von der Sitzauflage bekommt,aufgenommen werden,und dadurch das Rückgrat des Autofahrers-sprich Bandscheibe- entlastet.Oscillating cushion for car seat backrest Description Subject matter of the invention is an oscillating cushion for car seat backs, with which the diverse, small and large Vibrations that the driver receives from the seat cover are absorbed, and This relieves the driver's backbone, i.e. the intervertebral disc.

Der Stand der Technik hat bis heute in dieser Richtung wenig zu bieten.Zwar sind die Sitze,im Vergleich zu früher,grundlegend verbessert,d.h.der Körperform besser angepaßt worden.To date, the state of the art has little to offer in this direction the seats are fundamentally improved compared to before, i.e. the body shape better adapted.

Auch der Federkomfort und der seitliche Halt wurde verbessert.The spring comfort and lateral support have also been improved.

Gerade der gleichmäßige Druck des Körpers auf den Sitz bewirkt, daß der Körper regelrecht am Sitz klebt.Dies ist im ersten Anschein wohltuend auf -den Körper,hat aber den Wachteil,daß der Oberkörper nicht mehr in der Lage ist,die Schwingungen des Gesäßes, hervorgerufen durch die Autositzauflage, mitzumachen,weil eben das Gesäß am Sitz und der Oberkörper an der Lehne regelrecht haften.Die Cordstoffe rufen diese Haftung noch stärker hervor,als Z.B. Skai-Bezug.It is precisely the even pressure of the body on the seat that causes the body literally sticks to the seat, which at first glance is beneficial Body, however, has the watchful part that the upper body is no longer able to absorb the vibrations of the buttocks, caused by the car seat pad, to participate, because that is Buttocks really stick to the seat and the upper body to the backrest this adhesion is even more evident than, for example, a Skai cover.

Die Folge ist,daß die Rückgratwirbel am schwächsten Punkt(die unteren Lendenwirbel),dauernd edehnt,gezerrt und auch kreisförmig gescheuert werden,was auf längere Sicht zwangsläufig zu Bandscheibenschaden führt.Die Muskelpartien werden an dieser Stelle werden außerdem geschwächt,da sie nicht mehr gefordert werden,das Körpergewicht selbstfedernd aufzufangen,denn die tasse des Oberkörpers bleibt-noch unterstützt durch die Arme am Lenkrad- an der Lehne haften,während nur das Gesäß den Schwingungen der Autositzauflage nachgibt.The result is that the spinal vertebrae are at their weakest point (the lower Lumbar vertebrae), are constantly stretched, pulled and also rubbed in a circular manner, what In the long run, this inevitably leads to disc damage at this point are also weakened, since they are no longer required, the To absorb body weight self-resiliently, because the cup of the upper body still remains supported by the arms on the steering wheel- stick to the backrest, while only the buttocks yields to the vibrations of the car seat cover.

Der Zweck meiner Erfindung ist,die Möglichkeit zu schaffen,daß der ganze Oberkörper mit dem Gesäß gleichmäßig den Schwingungen folgt.Diese Wirkung wird hervorgebracht durch ein in die Lehne eingesetztes Schwingpolster,welches genau die Auf-Abwärts-Schräg-und Kreisbewegungen des Rückens mitmacht.Dadurch wird bewirkt, daß das Körpergewicht einerseits selbstfedernd durch die Lendenmuskel und andererseits durch die Federung der Sitzauflage aufgenommen wird.The purpose of my invention is to make it possible for the the whole upper body with the buttocks evenly follows the vibrations. This effect is brought about by an oscillating cushion inserted in the backrest, which exactly participates in the up and down oblique and circular movements of the back. that the body weight on the one hand self-resilient by the lumbar muscles and on the other hand is absorbed by the suspension of the seat pad.

Die Fig.a,b und c zeigen die frühere und modernere Sitzform.Figures a, b and c show the earlier and more modern seat shape.

Die Big.d und e zeigen,wie bei solchen Sitzen herkömmlicher Art die Lendenwirbel gedehnt werden.The Big.d and e show how the Lumbar vertebrae are stretched.

Die Fig.f zeigt einen Sitz mit eingebautem Schwingpolster.Fig.f shows a seat with built-in vibrating cushion.

Die Fig.g und h zeigen die Wirkung dieses Schwingpolsters.The Fig.g and h show the effect of this cushion.

Der ganze Körper gibt der Schwingungsamplitude nach,obwohl er voll an der Lehne aufliegt.Die Lendenmuskel und die Sitzauflagefedern allein nehmen das Körpergewicht auf und schützen die Wirbel vor Bandscheibenschaden.The whole body gives in to the vibration amplitude, although it is full The lumbar muscles and the seat support springs alone take that away Body weight and protect the vertebrae from damage to the intervertebral discs.

Die Funktion ist sehr einfach:Das Schwingpolster wird,wie Fig.i zeigt,an der Rückseite der Lehne befestigt,und kann verschiedenartig ausgebildet sein.Das in Fig.i gezeigte Polster bssteht aus einem elastischen Kissen mit LuStfüllung.Die Außenschicht kann ebenfall mit Stoffmuster versehen sein.The function is very simple: The oscillating cushion is, as Fig.i shows, on attached to the back of the backrest, and can be designed in various ways The cushion shown in Fig.i consists of an elastic cushion with luSt filling The outer layer can also be provided with a fabric pattern.

Eine Stützschale verhindert,daß das Kissen sich zusammenwälzt.(2) Eine andere Möglichkeit zeigt Fig.k u.l.Durch konische Rollen, und mehrere Bänder kann die Schwingung des Oberkörpers ebenfalls aufgenommen werden. A support shell prevents the pillow from rolling together. (2) Another possibility is shown in Fig.k.Ul by means of conical rollers, and several straps can also absorb the vibration of the upper body.
