Die Erfindung betrifft ein Polsterelement gemäß dem Oberbegriff des Hauptanspruches. The invention relates to a cushion element according to the preamble of the main claim.
Es wird grundsätzlich ein Polsterelement, z. B. Basically, a cushion element, e.g. B.
eine Matratze, angestrebt, die sich durch einen niedrigen Maximaldruck und einen hohen Stützfaktor auszeichnet. Ein niedriger Maximaldruck ist wichtig für eine unbehinderte Durchblutung. Die Größe des Stützfaktors gibt an, wie weit der Lendenwirbel- bereich im Vergleich zur Gesäßregion durch die a mattress that is characterized by a low maximum pressure and a high support factor. A low maximum pressure is important for an unimpeded blood flow. The size of the support factor indicates how far the lumbar region through the compared to the buttocks region

Ein hoher Stützfaktor ist aus biomechanischer und orthopädischer Sicht zum Schutz der Wirbelsäule und der Bandscheiben wünschenswert, während ein nied- riger Maximaldruck Durchblutungsstörungen reduziert.  Spring properties of the lying system is supported. 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.
Ein hoher Stützfaktor stützt die Wirbelsäule zumeist gut ab, läßt aber den Körper vor allem an den Vorsprüngen nicht ausreichend tief einsinken. Muskel verspannungen und Druckschmerzen können die Folge sein. Dabei ist der Schlafende unbewußt bemüht, dem Schmerzpunkt durch häufigen Positionswechsel und Körperdrehung auszuweichen, so daß Schlaftiefe und Komfortgefühl darunter leiden. Insbesondere ältere Menschen, deren Muskulatur nicht mehr so elastisch ist, können sich durch die mangelnde Einsinktiefe einer zu harten Matratze sehr gestört fühlen. Ein niedriger Maximaldruck der Matratze nimmt denA high support factor usually supports the spine well, but does not allow the body to sink deep enough, especially at the protrusions. muscle This can result in tension and pressure pains. The sleeper is subconsciously trying to avoid the pain point by frequent changes of position and body rotation, so that depth of sleep and feeling of comfort suffer. Older people in particular, whose muscles are no longer as elastic, can feel very disturbed by the lack of sinking in of a mattress that is too hard. A low maximum pressure of the mattress takes that

Mattress the necessary spontaneous movements. Troughs and hollows are similarly problematic because they also force the body into a certain posture and promote spinal twisting.
Es ist also ein Bestreben, die Vorteile einer harten Matratze für orthopädisch richtiges Liegen mit den Vorteilen einer weichen Matratze für komfortables gewebsentlastetes Liegen zu verbinden. It is therefore an effort to combine the advantages of a hard mattress for orthopedically correct lying with the advantages of a soft mattress for comfortable tissue-relieved lying.
Aus der belgischen Patentschrift 853 293 ist eine Kunststoffschaummatratze bekanntgeworden, die ein Basisteil besitzt und einen Federungsteil . Das Federungsteil besteht aus einer Vielzahl von polygonalen Einzelstäbchen, die jeweils an ihren beiden Enden fest mit Schaums toffschi chten verbunden sind. Aus dem DE-GM 78 29 649 ist ein Schaumfederkörper für Matratzen bekanntgeworden, der aus einem rohrförmigen Schaumstoffteil besteht, dessen Wand zusätzlich mit einer Vielzahl von Öffnungen und From the Belgian patent 853 293 a plastic foam mattress has become known, which has a base part and a suspension part. The suspension part consists of a large number of polygonal single rods, each of which is firmly connected to the foam material at its two ends. From DE-GM 78 29 649 is a foam spring body known for mattresses, which consists of a tubular foam part, the wall of which also has a plurality of openings and
Höhlungen versehen ist. Rohrförmige Federkörper neigen aber zu unerwünschten Knickeigenschaften. Wenn zudem das Wandmaterial durch Einschnitte und Öffnungen geschwächt ist, wird diese Knickeigenschaft noch erhöht, so daß keine optimale Abstützung erfolgen kann.  Cavities is provided. However, tubular spring bodies tend to have undesirable kink properties. If, in addition, the wall material is weakened by incisions and openings, this kinking property is increased so that optimal support cannot take place.
Der Erfindung liegt die Aufgabe zugrunde, Federkörper zu schaffen, die ein punktuelles, weiches und doch stark stützendes Abfedern des aufliegenden Körpers ermöglichen, so daß hierdurch optimale Werte für Stützfaktor, Maximaldruck, Druckverteilung und Auflagefläche erreicht wird. The invention has for its object to provide spring bodies that allow a punctual, soft and yet strongly supportive cushioning of the body lying on it, so that optimal values for support factor, maximum pressure, pressure distribution and contact surface are thereby achieved.
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.

B. im Krankenhausbereich, die Federungsfunktion des 5.0 kPa serve as a guideline. The spring elements can be higher in weight than the base, but are always considerably softer than this. The upholstery element base is a preferred component for a mattress with orthopedically correct values and it is always much harder than the actual spring elements.

Die Basis kann bestehen aus Produkten der Schaumstoff-Familie offen- oder geschlossenzellig aus Weich- und auch Hartschaum. Sie kann aber auch hergestellt sein aus Rohstoffen auf Faserbasis. The height of the cushion element base can be approximately 30 to 70% of the total height of the actual cushion element. The base can consist of products from the foam family with open or closed cells made of soft and hard foam. But it can also be made from fiber-based raw materials.

Vorzugsweise wird eine härtere Grundbasis und eine darauf angeordnete weichere Oberbasis vorgeschlagen, so daß eine progressive Elastizität erreicht wird. A harder base and a softer upper base arranged thereon are preferably proposed so that progressive elasticity is achieved.
Auf der Polsterelementbasis wird das Federungssystem angeordnet, das aus einzelnen Federkörpern besteht. Es ist möglich, das Federungssystem auf einer eigenen, beispielsweise aus Gewebe, Gewirke, Vlies od. dgl. bestehenden Tragschicht aufzubringen, wobei diese Schicht dann auf die Oberseite der Polsterelementbasis aufgelegt wird. Die Federkörper können an der sie tragenden Schicht, d. h. entweder an der Polsterelementbasis oder an der für sie vorgesehenen Tragschicht, dadurch befestigt sein, daß sie z. B. angeklebt sind, daß sie Klettverschlüsse aufweisen oder daß sie in entsprechende Ausnehmungen einer elastischen Tragschicht eingepaßt sind. The suspension system, which consists of individual spring bodies, is arranged on the cushion element base. It is possible to apply the suspension system to its own base layer, which consists, for example, of fabric, knitted fabric, fleece or the like, this layer then being placed on the top of the cushion element base. The spring body can on the supporting layer, i.e. H. either on the cushion element base or on the base layer provided for them, in that they are attached e.g. B. are glued that they have Velcro closures or that they are fitted into corresponding recesses of an elastic base layer.
Die Federkörper bestehen vorzugsweise aus PUR- Schaumstoff oder Latex. The spring bodies are preferably made of PUR foam or latex.
Die Federelemente dienen dazu, The spring elements serve
die gewünschten Elastizitätseigenschaften und weit darüber hinausgehende Eigenschaften wie Druckentlastung in der Dekubitus-Prophyl axe und Therapie zu bewirken. Ebenso dienen sie dazu, auch auf Basis einer besseren Unterstützung den Komfort zu erhöhen, der z. B. durch eine "weiche", angenehme Lordosenstreckung der Wirbelsäule bewirkt wird. Sie können rund, oval oder doppelkegelförmig sein. Wichtig ist, daß mit den Federkörpern eine Kombination aus Formelastizität und Volumenelastizität erreichbar ist. Unter Elastizität versteht man die Fähigkeit eines Körpers, durch äußere Kräfte oder to achieve the desired elasticity properties and properties that go far beyond this, such as pressure relief in the pressure ulcer prophylaxis and therapy. They also serve this purpose, also based a better support to increase the comfort z. B. is caused by a "soft", pleasant lumbar extension of the spine. They can be round, oval or double-conical. It is important that a combination of formula elasticity and volume elasticity can be achieved with the spring bodies. Elasticity means the ability of a body, through external forces or
Momente verursachte Form- oder Volumenänderungen rückgängig zu machen, d. h. seine vor dem Aufbringen der äußeren Einwirkung vorhandene Gestalt hinsichtlich aller Abmessungen und Winkel wieder anzunehmen. Ändert sich dabei lediglich die Form, so spricht man von einer Formelastizität, ändert sich aber auch die Größe des Federkörpers, so spricht man von Volumenelastizität.  Undo changes in shape or volume caused by moments, d. H. to resume its existing shape in all dimensions and angles before applying the external influence. If only the shape changes, one speaks of a formula elasticity, but if the size of the spring body also changes, one speaks of volume elasticity.
Die Dimensionierung des kleinsten Federkörper, und zwar des kreisförmig ausgebildeten, elastischen Formkörpers, beginnt bei einem Durchmesser von z. B. ca. 25 mm. Die Federkörper können gleichmäßig oder entsprechend einem bestimmten Anforderungsprofil angepaßt angeordnet sein. Ebenfalls ist vorgesehen, daß die Federkörper innerhalb einer Matratze bzw. eines Polsterteils aus unterschiedlichen Materialien bestehen können, und zwar sowohl in Bezug auf ihre Materialzusammensetzung, ihrem statischen The dimensioning of the smallest spring body, namely the circular, elastic molded body, begins with a diameter of z. B. approx. 25 mm. The spring bodies can be arranged evenly or adapted to a specific requirement profile. It is also provided that the spring bodies within a mattress or a cushion part can consist of different materials, both in terms of their material composition, their static

Der so hergestellte Polsterelement-Aufbau, bestehend aus Polsterelement-Basis und einem Federungssystem, bestehend aus einzelnen Federkörpern, die nicht miteinander verbunden sind, und gleichmäßig oder partiell (z. B. bei Aussparungen) auf der Polsterelement-Basis aufgebracht sind, bestehend aus The cushion element structure thus produced, consisting of a cushion element base and a suspension system, consisting of individual spring bodies which are not connected to one another, and uniformly or are partially applied (e.g. in the case of cutouts) to the cushion element base, consisting of
Schaumstoffen jeglicher Art, Latex, sind die Elemente der Erfindung.  Foams of any kind, latex, are the elements of the invention.
Eine weitere Abdeckung mit Polstermaterialien kann für verschiedene Einsatzzwecke sinnvoll sein. Allerdings ist auch Sinn der Erfindung, daß dieser Aufbau direkt ummantelt wird mit einer Umhüllung aus Geweben, Gewirken, Wattevliesen usw. In vielen Fällen wird die Gesamtkonstruktion einen Rahmen aufweisen, der unterschiedlich stark sein kann. Je nach Einsatzzweck kann es jedoch auch sinnvoll sein, auf diesen zu verzichten. A further covering with upholstery materials can be useful for different purposes. However, it also makes sense of the invention that this structure is directly coated with a covering made of woven, knitted, cotton fleece etc. In many cases, the overall construction will have a frame that can be of different thicknesses. Depending on the application, however, it can also make sense to do without it.

Spring body individually and thus elastically supports or cushions every part of the body, so that extremely high point elasticity is achieved over the entire cushion element.
Zusammenfassend ist also festzustellen, daß eine hohe Körperkonturanpassung bei hoher Druckentlastung und gutem Stützeffekt bei gleichzeitiger Lordosenstreckung erreicht wird und alle diese vorteilhaften Eigenschaften mit einer guten Klimatisierung verbunden sind. In summary, it can be stated that a high body contour adaptation with high pressure relief and good support effect with simultaneous lumbar extension is achieved and all these advantageous properties are associated with good air conditioning.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Die Zeichnung zeigt dabei in Fig. 1 in einer auseinandergezogenen Darstellungsweise den Aufbau des erfindungsgemäßen Polsterelementes, in An embodiment of the invention is explained below with reference to the drawing. The drawing shows in Fig. 1 in an exploded view, the structure of the cushion element according to the invention, in
Fig. 2 einen Schnitt durch ein Basisteil und in  Fig. 2 shows a section through a base part and in
Fig. 3 einen Schnitt durch ein abgeändertes  Fig. 3 shows a section through a modified
Basisteil. In den Zeichnungen ist mit 1 ein Basisteil bezeichnet, das aus einer Schicht bestehen kann oder gemäß Fig. 2 aus den beiden aufeinander angeordneten  Base part. In the drawings, 1 denotes a base part, which can consist of one layer or, according to FIG. 2, of the two parts arranged one on top of the other
Schichten 6 und 7 gebildet ist. Bei der Ausführungsform gemäß Fig. 3 ist das Basisteil kastenförmig ausgebildet, wobei die Größe der eigentlichen Ausnehmung 9 unterschiedlich sein kann, d. h. sich in etwa über die ganze Länge des Basisteiles erstreckt oder auch nur über einen Teil der Länge, der dann in besonderer Weise abgefedert werden soll.  Layers 6 and 7 is formed. In the embodiment according to FIG. 3, the base part is box-shaped, the size of the actual recess 9 can be different, i. H. extends approximately over the entire length of the base part or only over part of the length, which is then to be cushioned in a special way.
Auf das Basisteil ist das eigentliche Federungsteil 2 aufgelegt, das bei dem dargestellten Ausführungsbeispiel aus einer Tragschicht 8 besteht, die beispielsweise eine textile Gewebebahn, Gewirkebahn od. dgl. oder eine elastische Tragschicht sein kann, auf die Federkörper 4 aufgesetzt sind. Die Federkörper 4 können dabei auf der Tragschicht 8 aufgeklebt, aufgeklettet oder eingepaßt sein, und es ist in gleicher Weise möglich, die Federkörper 4 auch unmittelbar auf die Oberseite des Basisteiles 1 aufzubringen. Die eigentlichen Federkörper 4 können unterschiedlich gestaltet sein und als Ausführungsbeispiel sind die Federkörper 4a und 4b dargestellt, wobei die Federkörper 4 im wesent- liehen zylindrisch ausgebildet sind und damit im wesentlichen nur materialelastisch ausgebildet sind, während der Federkörper 4b zusätzlich eine Formelastizität aufweist, die durch die unterschiedliche Gestaltung erzielt wird. Auch können, wie bei dem Federkörper 4a dargestellt, die Federkörper aus unterschiedlichen Schichten aufgebaut sein. The actual suspension part 2 is placed on the base part, which in the exemplary embodiment shown consists of a support layer 8, which can be, for example, a textile fabric web, knitted fabric or the like, or an elastic support layer, on which spring bodies 4 are placed. The spring body 4 can be glued, clipped or fitted onto the support layer 8, and it is possible in the same way to apply the spring body 4 directly to the top of the base part 1. The actual spring bodies 4 can be designed differently, and the spring bodies 4a and 4b are shown as an exemplary embodiment, the spring bodies 4 being essentially cylindrical and thus in the are essentially only material-elastic, while the spring body 4b additionally has a formality which is achieved by the different design. Also, as shown in the spring body 4a, the spring bodies can be constructed from different layers.
Bei dem dargestellten Ausführungsbeispiel ist auf das Federungsteil eine Schicht von Polstermaterialien 5 aufgebracht und der Gesamtaufbau wird durch einen Überzug 3 abgedeckt. Hierbei ist es selbstverständlich möglich, daß das Polstermaterial 5 gleichzeitig steppdeckenartig in den Überzug 3 eingearbeitet ist. In the illustrated embodiment, a layer of cushioning material 5 is applied to the suspension part and the entire structure is covered by a coating 3. It is of course possible here that the cushioning material 5 is incorporated into the cover 3 at the same time as a quilt.
Wie bereits vorstehend ausgeführt, können alle Teile des erfindungsgemäßen Polsterelementaufbaus aus synthetischen oder natürlichen Werkstoffen bestehen und es ist ein wesentliches Merkmal des dargestellten Polsterelementaufbaus, daß eine progressive Elastizität von unten nach oben erreicht wird. As already stated above, all parts of the cushion element structure according to the invention can consist of synthetic or natural materials and it is an essential feature of the cushion element structure shown that a progressive elasticity is achieved from bottom to top.
