Description

Die Erfindung bezieht sich auf eine Matratze unter Verwendung von Polsterkörpern aus Weichschaum.The invention relates to a mattress using cushioning bodies made of soft foam.

Aus der EP-B1-236 668 ist ein Polsterkörper aus Weichschaum für den Bettwarenbereich, die Matratzen­industrie od. dgl. bekannt, wobei dieser Polsterkör­per im wesentlichen dadurch gebildet wird, daß mehrere Schaustoffbahnen miteinander verbunden sind, die beidseitig durch Gewebe-, Gewirke-, Vlies- oder Folienbahnen abgedeckt sind. Die Schaumstoffbahnen sind dabei mit im Abstand voneinander angeordneten, die Schaumstoffbahnen geradlinig und ganz, d.h. von der Ober- bis zur Unterseite durchquerenden Stanz­schnitten ausgerüstet, wobei diese Stanzschnitte rechtwinklig zueinander angeordnet sind und senk­recht zur Oberfläche der Schaumstoffbahnen geführt sind.From EP-B1-236 668 a cushion body made of soft foam for the bedding area, the mattress industry or the like is known, whereby this cushion body is essentially formed by the fact that several foils are connected to each other, which are woven and knitted on both sides, Fleece or foil webs are covered. The foam sheets are spaced from each other, the foam sheets are straight and complete, i.e. from the top to the bottom crossing punch cuts equipped, these punch cuts are arranged at right angles to each other and are perpendicular to the surface of the foam sheets.

Der Erfindung liegt die Aufgabe zugrunde, eine Ma­tratze zu schaffen, bei der die bekannten Polster­körper sinnvoll derart eingesetzt werden, daß die Matratze ein anotomisch richtiges Liegen ermöglicht. Außerdem soll sie sich durch progressiven Polster­aufbau dem persönlichen Gewicht stützend anpassen.The invention has for its object to provide a mattress in which the known cushion body are used in such a way that the Mattress allows anotomically correct lying. In addition, it should adapt to the personal weight by means of progressive upholstery.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteran­sprüchen erläutert.Advantageous configurations are explained in the subclaims.

Das so geschaffene vierlagige Verbundsystem ermög­licht eine ausgewogene, dauerhafte Stützkraft mit Federungseigenschaften, die den medizinischen Anfor­derungen nach gesundem Liegen entsprechen. Bei Band-­Kreuz- oder Nackenschmerzen bietet die neue Matratze eine wirksame Hilfe zum erholsamen Schlaf, weil die Wirbelsäule anatomisch richtig gelagert wird. Druck- oder Durchblutungsstörungen werden vermieden, weil eine Muldenbildung durch die einzigartige Punktela­stizität ausgeschlossen ist. Die Auflage und der Kern der Matratze geben dem Druck des Körpers nicht nur nach, sondern stützen und entspannen ihn an seinen empfindlichen Stellen. Die neue Matratze paßt sich der Wirbelsäule in den wechselnden Schlaflagen flexibel an. Die eingesetzten Polsterkörper nehmen der Matratze die Spannung, lassen die Luft frei zir­kulieren und sorgen somit für eine ständige Frische. Die eigentliche Polsterauflage ist abnehmbar und kochwaschbar. Diese ideale Reinigungsmöglichkeit ist in der häuslichen Krankenpflege ein nicht zu unter­schätzender Vorteil.The four-layer composite system created in this way enables a balanced, permanent support force with suspension properties that meet the medical requirements for healthy lying. In the case of low back pain or neck pain, the new mattress offers effective help for restful sleep because the spine is positioned anatomically correctly. Pressure or circulatory disorders are avoided because the unique point elasticity prevents the formation of troughs. The support and the core of the mattress not only give in to the pressure of the body, but also support and relax it in its sensitive areas. The new mattress adapts flexibly to the spine in the changing sleeping positions. The cushion bodies used remove the tension in the mattress, allow the air to circulate freely and thus ensure constant freshness. The actual upholstery is removable and washable. This ideal cleaning option is an advantage that should not be underestimated in home nursing.

Die Teilung der Matratze zwischen Auflage, Polster und Kern ermöglicht die Verwendung von wasserdichten Betteinlagen.The division of the mattress between support, cushion and core enables the use of waterproof bed inserts.

Ein Ausführungsbeispiel der Erfindung wird nachfol­gend anhand der Zeichnung erläutert.An embodiment of the invention is explained below with reference to the drawing.

In der Zeichnung ist ein Matratzenausschnitt darge­stellt. Die Matratze besteht im wesentlichen aus einem Polsterkern 1, der im eigentlichen Liegebe­reich eine Ausnehmung 2 aufweist. In diese Ausneh­mung 2 wird ein Polsterkörper 5 eingesetzt, der aus zwei Schaumstoffbahnen 3 und 4 besteht, die mitein­ander durch punktförmige oder strichförmige ma­terialschlüssige Verbindungsstellen verbunden sind, wobei die Schaumstoffbahn 3 zudem in gleicher Weise mit der Oberseite der Ausnehmung 2 verbunden ist.A mattress section is shown in the drawing. The mattress essentially consists of a cushion core 1 which has a recess 2 in the actual lying area. In this recess 2, a cushion body 5 is inserted, which consists of two foam sheets 3 and 4, which are connected to one another by punctiform or line-shaped material connection points, the foam sheet 3 is also connected in the same way to the top of the recess 2.

Die Schaumstoffbahnen 3 und 4 weisen die geradlini­gen und die Schaumstoffbahnen ganz durchsetzenden Stanzschnitte auf.The foam sheets 3 and 4 have the straight-line and completely penetrating die cuts.

Die so gebildete Einheit wird von einer Vliesumhül­lung 7 umgeben und zusammengefaßt.The unit thus formed is surrounded and combined by a nonwoven covering 7.

Die Vliesumhüllung 7 wird von einem abnehmbaren Jerseybezug 8 umgeben, der damit waschbar und aus­wechselbar ist.The nonwoven covering 7 is surrounded by a removable jersey cover 8, which is washable and replaceable.

Nach außen hin ist wiederum eine Schaumstoffbahn 6 vorgesehen ist, die somit einen Polsterkörper bildet, wobei diese Schaumstoffbahn 6 ebenfalls die geradlinigen und sie ganz durchquerenden Stanz­schnitte aufweist. An der Unterseite der Schaum­stoffbahn 6 ist ein Jerseybezug 10 vorgesehen und die Außenseite der Schaumstoffbahn 6 wird von einem Wirkfrottierbezug 9 umgeben, der liegefreundlich ist. Der Wirkfrottierbezug 9 ist mit dem Jerseybezug 10 über Stepplinien 12 verbunden, wodurch auch die Schaumstoffbahn 6 eingefaßt wird. Nicht dargestellt ist die Möglichkeit, daß die Einheit aus Bezug 9, Bezug 10 und Schaumstoffbahn 6 abnehmbar ausgebildet ist. Zwischen die Schaumstoffbahn 6 und die sich darunter befindende Matratze kann eine wasserdichte Einlage 11 eingeschoben werden. Somit ist diese Ma­tratze z. B. auch für die Altenpflege und insbeson­dere die häusliche Altenpflege besonders gut geeig­net, da die empfindlichen Teile leicht waschbar sind und das Einsetzen der wasserdichten Einlage problem­los möglich ist.Towards the outside, a foam sheet 6 is again provided, which thus forms a cushion body, this foam sheet 6 likewise having the straight-line and completely traversing die cuts. A jersey cover 10 is provided on the underside of the foam sheet 6 and the outside of the foam sheet 6 is surrounded by a knitted terry cover 9 which is easy to lie on. The knitted terry cover 9 is connected to the jersey cover 10 via quilting lines 12, which also means that Foam sheet 6 is bordered. Not shown is the possibility that the unit of cover 9, cover 10 and foam sheet 6 is removable. A waterproof insert 11 can be inserted between the foam sheet 6 and the mattress located underneath. Thus, this mattress is e.g. B. also particularly suitable for elderly care and in particular for home elderly care, since the sensitive parts are easily washable and the insertion of the waterproof insert is possible without any problems.

Vorzugsweise bestehen die Schaumstoffbahnen aus einem Polyurethanschaumstoff, in dem die Stanz­schnitte vorgesehen sind. Zur Verdeutlichung des Aufbaues der erfindungsgemäßen Matratze wird darauf hingewiesen, daß beispielsweise der Polsterkern ein Raumgewicht von 40 kg/cbm aufweisen kann, die Schaumstoffbahn 3 ein Raumgewicht von 30 kg/cbm, die Schaumstoffbahn 4 ein Raumgewicht von 22 kg/cbm und die Schaumstoffbahn 6 ein Raumgewicht von 21 kg/cbm aufweisen kann.The foam sheets preferably consist of a polyurethane foam in which the die cuts are provided. To clarify the structure of the mattress according to the invention, it is pointed out that, for example, the cushion core can have a density of 40 kg / cbm, the foam sheet 3 a density of 30 kg / cbm, the foam sheet 4 a density of 22 kg / cbm and the foam sheet 6 can have a density of 21 kg / cbm.

Die Jerseybezüge bestehen aus 100 % Baumwolle und der Wirkfrottierbezug 9 aus einem Wirkfrottier mit 30 % Polyesteranteil.The jersey covers consist of 100% cotton and the knitted terry cover 9 consists of a knitted terry with 30% polyester.
