Description

Otto Liebig, Leipzig N 21, Straße d. Deutsch-Soj. Freundschaft 117 Pneumatische verstellbare Rückenstütze für Sitze Die Erfindung bezieht sich auf eine pneumatische verstellbare Rückenstütze für Sitze zur Entlastung der Wirbelsäule durch aufblasbare Luftkammern. Derartige Rückenstützen sind bereits vorgeschlagen worden. So hat z. B. der. Erfinder in einer früher' Anmeldung den Vorschlag gemacht, eine in der Höhe verstellbare Luftkammer anzuordnen, die durch Schlauchleitung mit einem vom Benutzer bedienbaren Druckball verbunden ist. In einer anderen Ausführung ist bereits vorgeschlagen worden, in die Polsterung der Rückenlehne eines Sitzes mehrere Luftkammern übereinander anzubringen, die keine Verbindung miteinander haben und wovon jede ein besonderes Ventil besitzt. Diese Ausführung hat sich nicht bewährt, da keine individuelle Einstellung der Luftpolster möglich ist. Die Rückenstütze muß den anatomischen Verhältnissen der zu stützenden Wirbelsäule angepaßt sein, um wirksam zu werden. Otto Liebig, Leipzig N 21, Street d. German Soy. Friendship 117 Pneumatic adjustable backrest for seats The invention relates to a pneumatic adjustable backrest for seats to relieve the spine through inflatable air chambers. Such back supports have already been proposed. So has z. B. the. In an earlier application, the inventor made the proposal to arrange a height-adjustable air chamber which is connected by hose to a pressure ball that can be operated by the user. In another embodiment it has already been proposed to mount several air chambers one above the other in the upholstery of the backrest of a seat, which have no connection with one another and each of which has a special valve. This version has not proven itself, as no individual adjustment of the air cushions is possible. The back support must be adapted to the anatomical conditions of the spine to be supported in order to be effective.

Es hat sich nun herausgestellt, daß eine wirklich gute Anpassung an die gelenkige Wirbelsäule nur dann erreicht werden kann, wenn mehrere, mindestens zwei Kammern übereinander angeordnet und durch Ausgleichsleitungen miteinander verbunden sind. In diesem Falle weicht bei Belastung die Luft aus der einen Kammer in eine andere aus und es engtsteht dadurch eine gleichmäßige massierende Abstützung der Wirbelsäule.It has now been found to be a really good match the articulated spine can only be reached if several, at least two chambers arranged one above the other and connected to one another by compensating lines are. In this case the Air out of one Chamber into another and it narrows thereby an even massaging Support of the spine.

Die beste Angleichung an den jeweils den Sitz benutzenden Körper ist dadurch gegeben, daß es der Benutzer in der Hand hat, durch Bedienung des Druckballes mehr oder weniger Luft in die Kammern einzubringen oder durch Bedienung des Ablaßventiles den Druck zu verringern.The best approximation to the body using the seat is given by the fact that the user has it in hand, by operating the pressure ball Bring more or less air into the chambers or by operating the drain valve to relieve the pressure.

Die kennzeichnenden Merkmale der Erfindung bestehen darin, daß mindestens zwei durch Ausgleichsleitungen miteinander verbundene Luftkammern vorgesehen sind, von denen eine durch eine Schlauchleitung mit einem außerhalb der Stütze angeordneten und vom Benutzer bedienbaren Druckball verbunden ist. Die Luftkammern werden zweckmäßig djLcMt übereinander innerhalb des Umschlages der sie tragenden Rückwand angeordnet und durch kurze Schlauchstücke miteinander verbunden.The characterizing features of the invention are that at least two air chambers connected to one another by compensating lines are provided, one of which is arranged by a hose line with one outside the support and the user-operated pressure ball is connected. the Air chambers are expediently djLcMt one above the other within the The envelope of the rear wall carrying them is arranged and connected to one another by short pieces of tubing.

Die Stütze selbst kann in Form eines an jeder Rückenlehne anbringbaren Kissens ausgeführt oder in die Polsterung einer Rückenlehne eingebaut sein.The support itself can be attached in the form of a to each backrest Run cushions or be built into the upholstery of a backrest.

Auf der Zeichnung ist die Rüokenstütze gemäß der Erfindung beispielsweise veranschaulicht.In the drawing, the back support according to the invention is for example illustrated.

Abb. l zeigt dieselbe in Form eines anbringbaren Kissens, teil- weise im Schnitt, in schaubildlicher Darstellung Abb. 2 die gleiche Anordnung an der Rückenlehne eines Sitzes, während in Abb, teilweise im Schnitt, angedeutet ist, wie eine derartige CD Rückenstütze in die Polsterung einer Rückenlehne einige- bautwerden kann. Fig. 1 shows the same in the form of an attachable cushion, partially wise in section, in diagrammatic representation Fig. 2 shows the same arrangement on the backrest of a seat, while in Fig, partly in section, is indicated as such CD Backrest in the upholstery of a backrest can be built.

Die eigentliche Stütze besteht aus einer Rückwand 1, in deren Umschlag 2 die Luftkammern 3, 4 angeordnet sind, wobei diese Luftkammern durch kurze Schlauchstücke 9 miteinander vorbunden sind. Die untere Luftkammer 3 ist mit einer Schlauchleitung versehen, die nach dem Druckball 8 führte Im Fall der Abb. l und 2 sind für den Durchzug der Haltebänder 7 auf der Rückwand 1 steife Verstärkungen 6 angebracht. Im Beispiel der Abb. 3 sind drei Luftkammern 3, 4, 4a vorhanden, die wiederum durch kurze Schlauchstücke 9 miteinander in Verbindung stehen. Auch hier ist die untere Luftkammer 3 mit einer Schlauchleitung verbunden, die zu dem Druckball 8 führt.The actual support consists of a rear wall 1, in the envelope 2 the air chambers 3, 4 are arranged, these air chambers by short pieces of hose 9 are pre-tied together. The lower air chamber 3 is with a hose line provided, which led to the pressure ball 8 In the case of Fig. 1 and 2 are for the Passage of the straps 7 on the rear wall 1 stiff reinforcements 6 attached. In the example of Fig. 3 there are three air chambers 3, 4, 4a, which in turn go through short pieces of tubing 9 are in communication with one another. Here, too, is the lower one Air chamber 3 is connected to a hose line which leads to the pressure ball 8.

Sowohl in der Ausführung der Abb. l als auch bei dem Einbau, in eine gepolsterte Rückenlehne nach Abb. 3 kann über der eigentlichen aufblasbaren Einheit eine Schaumgummiauflage 5 angeordnet werden. Bs ist natürlich auch möglich, die gesamte Polsterung in Schaumgummi auszuführen und entsprechende Kanäle für das Einsetzen der Luftkammern vorzusehen, wie überhaupt die Ausführung und der Einbau abweichend von der beispielsweisen Darstellung sein kann. Soist z. B. an. oh eine Ausführung möglich, be der eine Luft- kammer durch Trennwände in mehrere Einzelkammern aufgeteilt wird und bei der in den Trennwänden AusgIsLohsoffnungen vorgesehen sind.A foam rubber pad 5 can be arranged over the actual inflatable unit both in the embodiment of Fig. 1 and in the case of installation in a padded backrest according to Fig. 3. It is of course also possible to make the entire upholstery in foam rubber and to provide appropriate channels for the insertion of the air chambers, as the design and installation may differ from the example illustration. So is z. B. at. oh a design possible, with an air Chamber is divided into several individual chambers by partition walls and where outlet openings are provided in the partition walls.

Rückenstütze nach der Erfindung eignen sich besonders zur Verwendung für Sitze in Kraftwagen, Flugzeugen u.dgl.Back supports according to the invention are particularly suitable for use for seats in cars, airplanes and the like.
