Description

Die Erfindung bezieht sich auf eine Matratze gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a mattress according to the preamble of the main claim.

Der Erfindung liegt die Aufgabe zugrunde, eine preisgünstige Matratze unter Beibehaltung der ergonomischen, physiologischen und waschtechnischen Vorteile vorzuschlagen.The invention has for its object to propose an inexpensive mattress while maintaining the ergonomic, physiological and washing advantages.

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.

Mit anderen Worten ausgedrückt wird eine Matratze vorgeschlagen, die sich durch die folgenden zwei Eigenschaften auszeichnet, nämlich einen niedrigen Maximaldruck und einem hohen Stützfaktor. Ein niedriger Maximaldruck ist wichtig für eine unbehinderte Durchblutung. Die Größe des Stützfaktors gibt an, wie weit der Lendenwirbelbereich im Vergleich zur Gesäßregion durch die Federeigenschaften des Liegesystems gestützt wird. Ein hoher Stützfaktor ist aus biomechanischer und orthopädischer Sicht zum Schutz der Wirbelsäule und der Bandscheiben wünschenswert, während ein niedriger Maximaldruck Durchblutungsstörungen reduziert. Eine diesen Forderungen angepaßte Matratze soll aber außerdem im Randbereich einen gewissen Abstützungseffekt beim seitlichen Aufsitzen auf der Bettkante bewirken. Alle diese Forderungen werden durch die erfindungsgemäße Matratze erfüllt, die aus einfachen Platten aufgebaut wird, nämlich einer Basisplatte, die eine hohe Stauchhärte aufweist. Die Stauchhärte wird dabei in KPa (Kilopascal) angegeben, wobei ein KPa ungefähr einem Gewicht von einem Kilo auf 100 cm² - Fläche entspricht. Die Stauchhärte stellt also die Druckspannung dar, die sich einstellt beim Zusammendrücken eines genormten Prüfkörpers in Abhängigkeit vom Verformungsweg.In other words, a mattress is proposed which is characterized by the following two properties, namely a low maximum pressure and a high support factor. A low maximum pressure is important for an unhindered Blood flow. The size of the support factor indicates how far the lumbar region is supported by the spring properties of the lying system compared to the buttocks region. A high support factor is desirable from a biomechanical and orthopedic point of view to protect the spine and intervertebral discs, while a low maximum pressure reduces circulatory disorders. A mattress adapted to these requirements should also have a certain supporting effect in the edge area when sitting on the side of the bed. All of these requirements are met by the mattress according to the invention, which is constructed from simple plates, namely a base plate which has a high compression hardness. The compression hardness is given in KPa (kilopascal), whereby a KPa corresponds approximately to a weight of one kilo per 100 cm² area. The compression hardness thus represents the compressive stress that arises when a standardized test specimen is compressed depending on the deformation path.

Bei einfachstem Aufbau erfüllt die erfindungsgemäße Matratze also alle an eine Matratze zu stellenden Anforderungen, nämlich es werden die Vorteile einer harten Matratze für orthopädisch richtiges Liegen mit den Vorteilen einer weichen Matratze für komfortables gewebsentlastendes Liegen verbunden.With the simplest construction, the mattress according to the invention therefore fulfills all the requirements to be placed on a mattress, namely the advantages of a hard mattress for orthopedically correct lying are combined with the advantages of a soft mattress for comfortable tissue-relieving lying.

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

In der Zeichnung ist eine Matratze dargestellt, die aus einer Basisplatte 1, beispielsweise aus Polyurethanschaum oder Hohlfasern, hergestellt ist. Die Basisplatte 1 weist dabei eine Röhrenstanzung 4 auf und einen umlaufenden Randbereich 7, der ohne eine solche Röhrenstanzung 4 ausgerüstet ist, so daß dadurch bereits eine höhere Festigkeit im Randbereich 7 erreicht wird. Die den Körperregionen angepaßten Klima-Kanäle, die durch die Röhrenstanzung gebildet sind, durchziehen vertikal bei einem Durchmesser von 10 mm die Basisplatte 1.In the drawing, a mattress is shown, which is made of a base plate 1, for example made of polyurethane foam or hollow fibers. The Base plate 1 has a tubular punch 4 and a peripheral edge area 7, which is equipped without such a tubular punch 4, so that a higher strength is already achieved in the edge area 7. The climatic channels adapted to the body regions, which are formed by the tube punching, run vertically through the base plate 1 with a diameter of 10 mm.

Diese Klimakanäle sorgen durch die Bewegung beim Schlaf für einen ständigen umfangreichen Luft- und Feuchtigkeitsaustausch und bewirken somit ein optimales Bettklima.Through the movement during sleep, these climate channels ensure a constant, extensive exchange of air and moisture and thus create an optimal bed climate.

Anstelle einer Basisplatte 1 aus Polyurethanschaum kann auch eine verdichtete Faserkernkonstruktion vorgesehen sein, wobei beiden Platten ein hohes Raumgewicht von 40 bis 60 kg/m³ und eine hohe Stauchhöhe zugrundeliegt.Instead of a base plate 1 made of polyurethane foam, a compressed fiber core construction can also be provided, both plates being based on a high density of 40 to 60 kg / m³ and a high compression height.

Auf die Basisplatte 1 ist eine erste Auflageplatte 2 aufgelegt, die rapportmäßig ausgebildete Stanzschnitte 6 aufweist, wobei diese aus Schaumstoff gebildete Auflageplatte 2 an ihrer Unterseite punkt- oder strichförmig verklebt sein kann. Die Klebepunkte werden in einem Rastermaß aufgebracht, wobei die einzelnen Punkte 10 bis 70 mm voneinander entfernt sein können. Anstelle der Stanzschnitte 6 können auch Perforationen vorgesehen werden.On the base plate 1, a first support plate 2 is placed, which has repeat cuts 6, whereby the support plate 2 made of foam can be glued in a punctiform or dashed manner on its underside. The adhesive dots are applied in a grid dimension, whereby the individual dots can be 10 to 70 mm apart. Instead of the punch cuts 6, perforations can also be provided.

Bei einer bevorzugten Ausführungsform wird der gesamte Randbereich in beispielsweise 5 cm Breite vollflächig mit einem Klebstoff besprüht, so daß eine saubere, gut haftende Kante entsteht.In a preferred embodiment, the entire edge area, for example 5 cm wide, is sprayed over the entire area with an adhesive, so that a clean, well-adhering edge is produced.

Auf die Auflageplatte 2 ist eine Auflageplatte 3 aufgelegt, die ebenfalls rapportmäßig angebrachte Stanzschnitte 6 aufweist.A support plate 3 is placed on the support plate 2, which also has punch cuts 6 which are arranged in a repeat manner.

Bei 10 ist ein elastischer, luftdurchlässiger Schutzbezug erkennbar, der als anschmiegsame Trikotumhüllung zum Schutz von Matratzenkern und Auflagepolster ausgebildet ist. Die extreme Dehnbarkeit des Materials stellt dabei sicher, daß das exakt abgestufte Elastizitätsverhalten der Matratze für wirbelsäulengerechtes Liegen und komfortablen Liegekomfort uneingeschränkt erhalten bleibt.At 10, an elastic, air-permeable protective cover can be seen, which is designed as a supple tricot cover to protect the mattress core and padding. The extreme elasticity of the material ensures that the exactly graded elasticity behavior of the mattress for spine-appropriate lying and comfortable lying comfort is fully preserved.

Den Belangen der Klimaregulierung wird durch die offene Gewebestruktur Rechnung getragen.The open fabric structure takes account of the concerns of climate regulation.

Dieser Aufbau wird von einem Bezug umhüllt, der als Polsterüberzug 5 ausgebildet sein kann. Die punktelastische Polstereinlage aus rapportmäßig gestanztem Schaumstoff ist z. B. 20 mm stark, verlängert den Einsinkweg des Körpers und ist das 1-Tüpfelchen für den Liegekomfort.This structure is covered by a cover, which can be designed as a cushion cover 5. The point-elastic padding made of repeat-punched foam is z. B. 20 mm thick, extends the sinking path of the body and is the icing on the cake for lying comfort.

Der elastische Bezugsstoff aus Baumwoll-Strickfrottee, der mit breit angelegten Steppnähten fest mit der Polstereinlage verbunden ist, paßt sich hervorragend dem Elastizitätsverhalten des Matratzenkerns an.The elastic cover fabric made of cotton knitted terry cloth, which is firmly attached to the padding with wide quilting seams, adapts perfectly to the elasticity of the mattress core.

Eine Faser aus 80 % Baumwolle und 20 % Polyester garantiert dabei einen sehr guten Wärme- und Feuchtigkeitsaustausch und ist hautsymphatisch.A fiber made of 80% cotton and 20% polyester guarantees a very good exchange of heat and moisture and is skin-friendly.

Der Polsterbezug ist an drei Seiten mit einem durchgängigen Reißverschluß versehen. Er kann abgenommen und problemlos in der Waschmaschine gewaschen werden. Bei der langen Lebensdauer der Matratze ist dies ein besonderer Vorteil, der immer eine optimale Hygiene garantiert.The upholstery cover is provided with a continuous zipper on three sides. He can lose weight and can be easily washed in the washing machine. Given the long lifespan of the mattress, this is a particular advantage that always guarantees optimal hygiene.

Wie aus der Darstellung in der Zeichnung zu ersehen, sind auch die Randbereiche 11 der Auflageplatten 2 und 3 stanzschnittfrei ausgebildet, so daß hier die Auflagen eine höhere Widerstandsfähigkeit aufweisen als im mittleren Bereich.As can be seen from the illustration in the drawing, the edge regions 11 of the support plates 2 and 3 are also designed without punch cuts, so that the supports here have a higher resistance than in the central region.

Durch diesen Aufbau wird erreicht, daß der Randbereich der Matratze härter ausgebildet ist als der mittlere Liegebereich und dadurch ein sicheres Sitzen an dem Rand ermöglicht wird.This structure ensures that the edge area of the mattress is made harder than the central lying area and thereby enables a safe sitting on the edge.

Die Basisplatte 1 weist eine relativ hohe Stauchhärte zwischen 40 bis 60 KPa auf, während die obere Auflageplatte 3 eine sehr weiche Stauchhärte besitzt, die zwischen 8 und 30 KPa liegt. Die mittlere Auflageplatte 2 weist eine Stauchhärte auf, die zwischen 25 und 50 KPa liegt, so daß von unten nach oben ein eine nachlassende Stauchhärte aufweisender Aufbau der Matratze gewährleistet wird.The base plate 1 has a relatively high compression hardness between 40 to 60 KPa, while the upper support plate 3 has a very soft compression hardness which is between 8 and 30 KPa. The middle support plate 2 has a compression hardness which is between 25 and 50 KPa, so that from the bottom upwards a decreasing compression hardness of the mattress is guaranteed.

Während in der Zeichnung die Auflageplatten 2 und 3 als Schaumstoffbahnen mit Stanzschnitten dargestellt sind, ist es natürlich auch möglich, die eine oder andere Auflageplatte 2 oder 3 aus einem Polster aus Polsterfüllstäbchen herzustellen, die zum Stand der Technik gehören. So kann in Anpassung an die unterschiedlichen Anforderungen des Patienten auch ein unterschiedlicher Aufbau der Auflageplatten 2 und 3 gewählt werden, wobei alle heute zum Stand der Technik gehörenden Füllstoffe für derartige Einsatzzwecke auch hier zum Einsatz kommen können.While in the drawing the support plates 2 and 3 are shown as foam sheets with die cuts, it is of course also possible to produce one or the other support plate 2 or 3 from a cushion of cushion filler sticks, which belong to the prior art. In order to adapt to the different requirements of the patient, a different structure of the support plates 2 and 3 can also be selected, all of the fillers which are now part of the prior art for such uses can also be used here.

Die Auflageplatten können auch anstelle aus Polyurethanschaumstoff aus hoch verdichteten Faservliesen bestehen, die ebenfalls mit einer rapportmäßigen Stanzung versehen sind, wobei als Fasern hochelastische Fasern eingesetzt werden.Instead of polyurethane foam, the support plates can also consist of high-density nonwovens, which are also provided with a repeat punching, with highly elastic fibers being used as fibers.

Der vorbeschriebene grundsätzliche Aufbau führt zu einer Matratze, die einen hohen Stützfaktor aufweist und somit aus biomechanischer und orthopädischer Sicht zum Schutz der Wirbelsäule und Bandscheibe geeignet ist, während sie gleichzeitig einen niedrigen Maximaldruck gewährleistet, um somit eine unbehinderte Durchblutung sicherzustellen.The basic structure described above leads to a mattress that has a high support factor and is therefore suitable from a biomechanical and orthopedic point of view to protect the spine and intervertebral disc, while at the same time guaranteeing a low maximum pressure to ensure unimpeded circulation.
