Description
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
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-
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.
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.
