Description

Die vorliegende Erfindung betrifft eine Vorrichtung insbesondere zur Klimatisierung von Sitzmöbeln oder Liegemöbeln, mit einer wenigstens in ihrem Boden mit Lüftungsöffnungen versehenen Wanne, wobei die Lüftungsöffnungen der Wanne erhöhte Ränder aufweisen, insbesondere für den Care-Bereich.The present invention relates to a device, in particular for the air conditioning of seating or reclining furniture, with a provided at least in its bottom with vents tray, the vents of the tub have raised edges, especially for the care sector.

Für die Klimatisierung von Sitzmöbeln, insbesondere im Care-Bereich, dem Bereich, in dem pflegebedürftige Personen einer besonderen Unterstützung, insbesondere im Zusammenhang mit Grundpflege und Inkontinenzproblemen bedürfen, gibt es eine Reihe von einfachen Lösungen wie luft- und feuchtigkeitsdurchlässige Korbstühle, Stühle mit austauschbaren Sitzbezügen, oder einfache mit Abstandsgewirk versehene Stühle, welche eine Verbesserung der Hinterlüftung bringen sollen. Diese Sitzmöbel werden u. a. im Umfeld von Inkontinenzproblemen hygienisch stark beansprucht. Eine zufriedenstellende hygienisch einwandfreie Anwendbarkeit ist nicht durchweg gewährleistet. Im Automobilbereich werden Komfort-Sitze mit aktiver Hinterlüftung bis zu vollklimatisierten Sitz- und Lehnenbereichen vorgeschlagen. Alle diese Lösungen sind entweder extrem teuer oder unattraktiv in der Pflege oder wiederum nicht zufriedenstellend in der Wirkung. Daneben gibt es kaum Vorschläge für die Klimatisierung von Sitzmöbeln, welche sich individuelle Anforderungen entsprechend ökonomisch einstellen lassen.For the air conditioning of seating furniture, especially in the care sector, the area in which dependent persons require special support, especially in connection with basic care and incontinence problems, there are a number of simple solutions such as air-permeable and moisture-permeable wicker chairs, chairs with interchangeable seat covers , or simple provided with Abstandsgewirk chairs, which should bring an improvement in the rear ventilation. These chairs are u. a. Hygienically stressed in the context of incontinence problems. Satisfactory hygienic applicability is not consistently guaranteed. In the automotive sector, comfort seats with active rear ventilation up to fully air-conditioned seating and backrest areas are proposed. All of these solutions are either extremely expensive or unappealing in the care or again unsatisfactory in the effect. In addition, there are hardly any proposals for the air conditioning of seating furniture, which can be adjusted according to individual requirements economically.

Aus dem Patent US 3,940,183 ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt.From the Patent US 3,940,183 a device according to the preamble of claim 1 is known.

Die Aufgabe wird gelöst mit einer Vorrichtung zur Klimatisierung von Sitz- oder Liegemöbeln, welche durch eine wenigstens in ihrem Boden mit Lüftungsöffnungen versehene Wanne, gekennzeichnet ist, wobei die Lüftungsöffnungen der Wanne erhöhte Ränder aufweisen. Sich beim Einsatz im Pflegebereich gegebenenfalls im Bodenbereich der Wanne sammelnde Flüssigkeiten, z. B. Urin, Schweiß und dergl. können nicht durch die Lüftungsöffnungen austreten und abfließen und damit Verunreinigungen verursachen, sondern aufgenommen und entfernt werden. Damit ergibt sich ein beachtlicher Beitrag zur Steigerung der Hygiene.The object is achieved with a device for the air conditioning of sitting or lying furniture, which is characterized by a provided at least in its bottom with vents trough, wherein the vents of the trough have raised edges. When used in the care sector optionally in the bottom region of the tub collecting liquids, eg. As urine, sweat and the like. Can not escape through the ventilation holes and drain and thus cause contamination, but are absorbed and removed. This results in a considerable contribution to the increase in hygiene.

In einer weiteren vorteilhaften Ausbildung der Erfindung sind die Lüftungsöffnungen unterschiedlich groß und/oder in vorbestimmten Mustern am Boden der Sitzwanne angeordnet. Wie leicht nachzuvollziehen ist, so kann in Bereichen der am höchsten erwarteten Transpiration der Querschnitt der Lüftungsöffnungen größer ausgebildet sein. Ebenso kann in den genannten Bereichen eine größere Anzahl von Lüftungsöffnungen angeordnet sein, als in Bereichen, in denen mit weniger Transpiration zu rechnen ist.In a further advantageous embodiment of the invention, the ventilation openings are different in size and / or arranged in predetermined patterns at the bottom of the seat pan. As will be appreciated, in areas of highest expected perspiration, the cross-section of the vents may be made larger. Likewise, a larger number of ventilation openings can be arranged in the areas mentioned than in areas in which less perspiration is to be expected.

Eine weitere vorteilhafte Ausbildung der Erfindung ist gekennzeichnet durch einen auf dem Boden der Sitzwanne aufliegenden ersten Abstandskörper, welcher Ausnehmungen aufweist, in denen Federelemente angeordnet sind, und einen auf dem ersten Abstandskörper aufliegenden zweiten Abstandskörper, wobei wenigstens einer der Abstandskörper ein Abstandsgewirk ist, welches als klimatisierende Sitzunterlage im Stand der Technik bekannt ist und in der Regel aus zwei beabstandeten textilen Flächengebilden besteht, zwischen denen starke elastische Abstand haltende Fäden für einen konstanten Abstand der textilen Flächengebilde sorgen, wenn das Abstandsgewirk unbelastet ist, wobei durch die Anordnung der Abstand haltenden Fäden eine optimale Durchlüftung möglich ist.A further advantageous embodiment of the invention is characterized by a resting on the bottom of the seat pan first spacer body having recesses in which spring elements are arranged, and resting on the first spacer body second spacer body, wherein at least one of the spacer body is a Abstandsgewirk, which as air-conditioning seat pad is known in the art and usually consists of two spaced textile fabrics, between which strong elastic distance holding threads provide a constant distance of the fabric when the spacer fabric is unloaded, with the arrangement of the distance-holding threads a optimal ventilation is possible.

Eine derartige Vorrichtung, beispielsweise eingebaut in ein Sitzmöbel, beispielsweise einen Stuhl und überzogen mit einem individuell ausgesuchten Stuhlbezug bringt für die Klimatisierung einer darauf sitzenden Person, insbesondere im Gesäßbereich außerordentliche Vorteile. Vom Körper abgegebene Wärme und Feuchtigkeit kann durch den zweiten Abstandskörper und den darunter liegenden ersten Abstandskörper über die im Boden der Sitzwanne angeordneten Lüftungsöffnungen abgegeben werden. Setzt sich eine Person auf einen derart ausgestatteten Stuhl, so werden die Abstandskörper zusammengedrückt und die Luft, welche teilweise mit Feuchtigkeitspartikeln oder sonstigen Schwebstoffen durchsetzt ist, über die Lüftungsöffnungen der Sitzwanne aus dem Stuhl herausgepresst. Bei Entlastung der Sitzfläche wird automatisch frische Luft in den Abstandskörperbereich eingesaugt und sozusagen eine Erfrischung des Sitzmöbels erreicht. Durch die im ersten Abstandskörper angeordneten Federelemente wird die eben beschriebene "Atmung" des Sitzmöbels vorteilhafterweise unterstützt.Such a device, for example, installed in a chair, for example, a chair and covered with an individually selected chair cover brings for the air conditioning of a person sitting on it, especially in the buttocks area extraordinary advantages. Heat and moisture emitted by the body may be delivered through the second spacer body and the underlying first spacer body via the vents located in the bottom of the seat pan. If a person sits on such a chair, the spacer bodies are compressed and the air, which is partially interspersed with moisture particles or other suspended matter, is pressed out of the chair via the ventilation openings of the seat pan. Relieving the seat becomes automatic sucked fresh air into the spacer body area and, so to speak, achieved a refreshment of the chair. By means arranged in the first spacer body spring elements the just described "breathing" of the chair is advantageously supported.

Die Ausbildung der Sitzwanne mit sich zum Abstandskörper hin erstreckenden Lüftungsöffnungen, welche von erhöhten Rändern umgeben sind, sorgt dafür, dass eine zuverlässige hygienisch einwandfreie Reinigung eines mit der erfindungsgemäßen Vorrichtung ausgestatteten Sitzmöbels einfach und praktisch durchführbar ist. Dies macht die Erfindung insbesondere für den Pflegebereich so interessant. Beispielsweise werden im Falle einer Kontamination von Teilen der Vorrichtung mit Körperflüssigkeiten diese wie oben beschrieben aufgenommen und die vorteilhafterweise abwaschbar ausgebildete Sitzwanne gereinigt und desinfiziert. Die aus der Sitzwanne entfernten Abstandskörper, Federelemente, und ggf. Seitenriegel sowie Dekorbezüge werden gewaschen oder gereinigt und sind wieder einsatzfähig. Demnach ist die erfindungsgemäße Vorrichtung auch im Umfeld von Inkontinenzproblemen hervorragend einsetzbar, wobei die zufriedenstellende hygienisch einwandfreie Anwendbarkeit gewährleistet ist.The design of the seat pan with extending to the spacer body ventilation openings, which are surrounded by raised edges, ensures that a reliable hygienic cleaning of a device equipped with the device according to the invention is easy and practical to carry out. This makes the invention particularly interesting for the care sector. For example, in the event of contamination of parts of the device with body fluids, they are taken up as described above and the advantageously washable trained seat pan is cleaned and disinfected. The removed from the seat pan spacers, spring elements, and possibly side bars and decorative covers are washed or cleaned and are operational again. Accordingly, the device according to the invention is also excellent in the field of incontinence problems, the satisfactory hygienic applicability is guaranteed.

In einer weiteren vorteilhaften Ausbildung der Erfindung sind die Federelemente als Kunststoffkugeln oder -zylinder ausgebildet. Die durch diese Gestaltung sehr ökonomisch aufgewertete Vorrichtung zur Klimatisierung von Sitzmöbeln ist vorteilhafterweise derart ausgebildet, dass in die Abstandskörper beispielsweise zylindrische Bohrungen eingebracht werden, in welche Kunststoffkugeln oder -zylinder eingesetzt werden, die auf dem Boden der Sitzwanne ruhen und hierdurch beim Zurückfedern des zweiten Abstandskörpers der Vorrichtung bei Entlastung derselben ein Widerlager erfahren.In a further advantageous embodiment of the invention, the spring elements are designed as plastic balls or cylinders. The very economically upgraded by this design device for air conditioning of seating is advantageously designed so that in the spacer body, for example, cylindrical holes are introduced, in which plastic balls or cylinders are used, which rest on the bottom of the seat pan and thereby during spring back of the second spacer body the device when relieved of the same experience an abutment.

Eine weitere vorteilhafte Ausbildung der Erfindung besteht darin, dass die Kunststoffkugeln oder -zylinder unterschiedliche Härtegrade haben. Hierdurch lässt sich eine individuelle Anpassung der erfindungsgemäßen Vorrichtung an eine Person, welche auf einem beispielhaft hiermit ausgerüsteten Sitzmöbel sitzen soll, erreichen. Für eine sehr schwere, korpulente Person sind höhere Härtegrade erforderlich als für eine leichtere, grazile Person. Es hat sich darüber hinaus auch als vorteilhaft erwiesen, in verschiedenen Bereichen der Sitzmöbel unterschiedliche Härtegrade der Federelemente zu verwenden. Die Auswahl wird ebenfalls abhängig von der Individualität der entsprechenden Person ausgerichtet, für welche das entsprechende Sitzmöbel vorgesehen ist.A further advantageous embodiment of the invention is that the plastic balls or cylinders have different degrees of hardness. In this way, an individual adaptation of the device according to the invention to a person who is to sit on an example hereby equipped seating, reach. For a very heavy, corpulent person higher degrees of hardness are required than for a lighter, graceful person. It has also proven to be advantageous to use different degrees of hardness of the spring elements in different areas of the seating. The choice is also made depending on the individuality of the person for whom the corresponding seating is intended.

Darüber hinaus kann in einer vorteilhaften Weiterbildung der Erfindung der Wert der Vorrichtung zur Klimatisierung durch als Kunststoffkugeln ausgebildete Federelemente erhöht werden, welche eine Duftstoffe abgebende Masse aufweisen. Dies mag insbesondere im Care-Bereich von Vorteil sein, wobei unter dem Begriff Duftstoffe auch Stoffe gemeint sind, welche geruchsabsorbierende Eigenschaften haben.In addition, in an advantageous development of the invention, the value of the device for air conditioning can be increased by designed as a plastic balls spring elements having a fragrance-emitting mass. This may be particularly advantageous in the care sector, wherein the term fragrances also substances are meant, which have odor-absorbing properties.

In einer vorteilhaften Weiterbildung der Erfindung ist der erste Abstandskörper wenigstens teilweise seitlich von Seitenriegeln umgeben, welche beispielsweise aus einem gegenüber dem ersten Abstandskörper härteren elastischen Körper ausgebildet sein können, um den Übergang zwischen dem ersten Abstandskörper und dem Rand der Sitzwanne zu verstärken, um ihn damit einerseits verschleißfester, andererseits auch bedienungsfreundlicher und komfortabler zu gestalten.In an advantageous embodiment of the invention, the first spacer body is at least partially laterally surrounded by side bars, which may be formed, for example, of a relative to the first spacer body harder elastic body to reinforce the transition between the first spacer body and the edge of the seat pan to him on the one hand wear-resistant, on the other hand also user-friendly and comfortable to design.

Zum besseren Verständnis der Erfindung wird diese im Folgenden anhand eines Ausführungsbeispiels unter Zuhilfenahme einer Zeichnung kurz beschrieben.

For a better understanding of the invention, this will be briefly described below with reference to an embodiment with the aid of a drawing.
Fig. 1
shows a highly schematic perspective view of the outlines of a chair with a seat pan used in the device according to the invention.
Fig. 2
shows that off Fig. 1 known chair, but already with an applied to the tub first spacer body with spring elements.

Figure 4
shows a cross section through the device according to the invention highly schematized as a partial sectional view cut along the line AA according to Fig. 2 ,

In Fig. 1 ist schematisch ein Stuhl 5 dargestellt, in welchem im Stuhlrahmenbereich auf Sitzhöhe eine erfindungsgemäße Vorrichtung mit einer Wanne, hier einer Sitzwanne 3, welche vorzugsweise aus Kunststoff hergestellt ist, eingesetzt ist. Im Boden 1 der Sitzwanne 3 sind Lüftungsöffnungen 2 angebracht. Aus der Konfiguration der Lüftungsöffnungen 2 im Boden 1 gemäß Fig. 1 kann man die Kontur der Kontaktfläche mit einer auf dem Stuhl sitzenden Person erkennen. Beispielhaft sind einige der Lüftungsöffnungen mit erhöhten Rändern 22 gezeigt. Weitere Einzelheiten hierzu finden sich in der Beschreibung zu Fig. 4.In Fig. 1 schematically a chair 5 is shown, in which in the chair frame area at seat height, a device according to the invention with a tub, here a seat pan 3, which is preferably made of plastic, is used. In the bottom 1 of the seat pan 3 ventilation openings 2 are mounted. From the configuration of the ventilation openings 2 in the bottom 1 according to Fig. 1 you can see the contour of the contact surface with a person sitting on the chair. Some are exemplary the vents with raised edges 22 shown. Further details can be found in the description Fig. 4 ,

In den Fig. 2 und 4 ist ein in die Sitzwanne eingelegter erster Abstandskörper 4 zu erkennen, welcher mit Ausnehmungen 6 versehen ist, in welche wiederum Federelemente 8 bzw. Kunststoffkugeln 4 oder Kunststoffzylinder 16 eingesetzt dargestellt sind. Auf dem ersten Abstandskörper 4 aufliegend ist, wie Fig. 4 zeigt, ein zweiter Abstandskörper 10 angeordnet, welcher in Fig. 4 auf der rechten Seite als Abstandsgewirk 10' schematisch als Teilbereich des zweiten Abstandskörpers 4 dargestellt ist. In die Ausnehmungen 6 sind Kunststoffkugeln 14 eingesetzt.In the Fig. 2 and 4 is to be recognized in the seat pan first spacer body 4, which is provided with recesses 6, in which in turn spring elements 8 and plastic balls 4 or plastic cylinder 16 are shown used. On the first spacer body 4 is resting, as Fig. 4 shows a second spacer body 10 is arranged, which in Fig. 4 on the right side as a spacer fabric 10 'is shown schematically as part of the second spacer body 4. In the recesses 6 plastic balls 14 are used.

Wenn man sich nun auf den zweiten Abstandskörper 10 der Darstellung nach Fig. 4 in Richtung der Pfeile L eine Kraft wirkend vorstellt, welche von einer auf dem zweiten Abstandskörper sitzenden Person ausgeht, dann kann man sich leicht vorstellen, dass bei einem Widerhalt durch den Boden 3 der erste Abstandskörper 4 sowie der zweite Abstandskörper 10 und auch die Federelemente 14 komprimiert werden und hierbei durch Lüftungsöffnungen 2 in Richtung der Pfeile B Abluft aus dem Bereich der Ausnehmungen 6 aus dem Sitzbereich abgeführt wird. Wird der Sitz, welcher schematisch bereichsweise in Fig. 4 dargestellt, wieder entlastet, d. h. eine in Richtung der Pfeile L wirkende Kraft wird weggenommen, werden die Federelemente 14 den zweiten Abstandskörper 10 wieder nach oben heben und dabei frische Luft 6 in die Ausnehmungen 6 in zu den Pfeilen B entgegengesetzter Richtung einsaugen. Dies ist die bereits oben diskutierte "Atmung" oder Passivbelüftung der erfindungsgemäßen Vorrichtung. Bei einer derartigen Kompression und Dekompression der Federelemente können diese, sofern sie mit einer Duftstoffe abgebenden Masse versehen sind, die Duftstoffe in den Raum geben. Ebenso könnten dabei unangenehmen Geruch absorbierende "Duftstoffe" zum Einsatz kommen.If you now look at the second spacer body 10 of the illustration Fig. 4 acting in the direction of arrows L, a force acting, which emanates from a person sitting on the second spacer body, then one can easily imagine that in a resistance through the bottom 3 of the first spacer body 4 and the second spacer body 10 and the spring elements 14th be compressed and this is discharged through ventilation openings 2 in the direction of arrows B exhaust air from the region of the recesses 6 from the seating area. Is the seat, which schematically in areas in Fig. 4 shown, relieved again, ie a force acting in the direction of arrows L force is removed, the spring elements 14, the second spacer body 10 again lift up and thereby suck fresh air 6 in the recesses 6 in the direction opposite to the arrows B direction. This is the "breathing" or passive ventilation of the device according to the invention already discussed above. With such a compression and decompression of the spring elements, these, if they are provided with a fragrance-emitting mass, give the fragrances in the room. Likewise, unpleasant odor-absorbing "fragrances" could be used.

Fig. 4 zeigt die Lüftungsöffnungen 2 der Sitzwanne 3 mit erhöhten Rändern 22, durch welche es erfindungsgemäß möglich wird, sich gegebenenfalls im Bodenbereich der Wanne sammelnde Flüssigkeiten, z. B. Urin, Schweiß und dergl. aufzufangen, sodass sie nicht durch die Lüftungsöffnungen austreten und abfließen und damit Verunreinigungen verursachen, sondern aufgenommen und entfernt werden können. Bei Bedarf können die Erhöhungen auch in dem Ausmaß wie die erhöhten Ränder 221 ausgebildet sein, um die Flüssigkeitsaufnahmefähigkeit der erfindungsgemäßen Vorrichtung stark zu erhöhen. Fig. 4 shows the ventilation openings 2 of the seat pan 3 with raised edges 22, by which it is possible according to the invention, optionally in the bottom region of the tub collecting liquids, eg. As urine, sweat and the like. Collect so that they do not escape through the ventilation holes and drain and thus cause contamination, but can be taken and removed. If desired, the ridges may also be formed to the same extent as the raised rims 221 to greatly increase the liquid holding capacity of the device of the invention.

In Fig. 3 ist noch eine vorteilhafte Abwandlung der erfindungsgemäßen Vorrichtung dargestellt. Man erkennt gut die zur Seite und zur Vorderkante des Sitzmöbels 5 hin orientierten Seitenriegel 20, welche einen Übergang vom ersten Abstandskörper 4 zum Stuhlrahmen 24 komfortabel gestalten. Selbstverständlich wird aus ästhetischen und praktischen Gründen über den zweiten Abstandskörper 10 der erfindungsgemäßen Vorrichtung ein Dekorationsstoff gezogen, um die an sich Vorteile bringende erfindungsgemäße Vorrichtung in dem entsprechenden Sitzmöbel aus ästhetischen Gründen zu kaschieren bzw. unsichtbar zu machen.In Fig. 3 is still an advantageous modification of the device according to the invention shown. It can be seen well oriented to the side and the front edge of the chair 5 out side latch 20, which make a transition from the first spacer body 4 to the chair frame 24 comfortable. Of course, a decorative fabric is drawn for aesthetic and practical reasons on the second spacer body 10 of the device according to the invention to conceal the advantages in itself device according to the invention in the corresponding seating for aesthetic reasons to make or invisible.

Die erfindungsgemäße Vorrichtung arbeitet nach dem Prinzip des aktiven Luft- und Feuchtigkeitsaustausches. Es werden hierdurch vorteilhafterweise Dampfmoleküle, welche beim Sitzen durch Schwitzen entstehen mit Unterstützung der durch die Federelemente 8 geförderten Lüftung durch den mit Lüftungsöffnungen 2 versehenen Boden 1 der Sitzwanne 3 in die Umgebung gefördert. Es ergibt sich für die auf dem Stuhl sitzende Person ein völlig neuartiges angenehmes Sitzgefühl. Die Federelemente 8, 14 und 16 massieren das Gewebe der Person im Oberschenkel- und Gesäßbereich und verbessern dadurch die Blutzirkulation. Abhängig vom Gewicht der betreffenden Person können die Härtegrade der Federelemente individuell ausgewählt werden. Darüber hinaus kann die Form der Federelemente 8 als Kunststoffzylinder 16 beispielsweise im hinteren Eckbereich des Sitzes und/oder in den Randzonen eingesetzt werden. Hierzu ist in Fig. 2 im rechten hinteren Eck schematisch die Anordnung von drei Zylindern 16 über Eck angedeutet.The device according to the invention operates on the principle of active air and moisture exchange. Thereby advantageously steam molecules, which are formed by perspiration when sitting with the support of the promoted by the spring elements 8 ventilation through the provided with vents 2 bottom 1 of the seat pan 3 into the environment. It results for the person sitting on the chair a completely new comfortable seating experience. The spring elements 8, 14 and 16 massage the tissue of the person in the thigh and buttocks area and thereby improve the blood circulation. Depending on the weight of the person concerned, the degrees of hardness of the spring elements can be selected individually. In addition, the shape of the spring elements 8 can be used as a plastic cylinder 16, for example in the rear corner region of the seat and / or in the edge zones. This is in Fig. 2 in the right rear corner schematically indicated the arrangement of three cylinders 16 at the corner.

Nachdem sämtliche Einzelteile der erfindungsgemäßen Vorrichtung bei im Care-Bereich erforderlichen Temperaturen gereinigt bzw. gewaschen werden können, ergeben sich in Kombination mit der hervorragenden Druck- und Feuchtigkeitsdurchlässigkeit der erfindungsgemäßen Vorrichtung optimale hygienische Eigenschaften. Diese werden begleitet von einem Optimum an Sitzkomfort.After all the individual parts of the device according to the invention can be cleaned or washed at temperatures required in the care sector, optimal hygienic properties result in combination with the outstanding pressure and moisture permeability of the device according to the invention. These are accompanied by an optimum of seating comfort.

Bei entsprechender Auswahl von mit Duftstoffen ausgestatteten Federelementen werden durch die Passivlüftung der erfindungsgemäßen Vorrichtung die in den Federelementen integrierten Duftstoffe freigesetzt, wobei sie auf Wunsch einen dezenten Duft eines ausgewählten Aromas hinterlassen können. Eine spezielle Ausrüstung für die erfindungsgemäß eingesetzten Abstandskörper und Abstandsgewirke verhindert die Bildung sowie das Einnisten gefährlicher Schimmelpilze und schränkt somit die Nahrungsquelle von Schädlingen, beispielsweise der Hausstaubmilbe, ein.With appropriate selection of perfume-equipped spring elements, the passive ventilation of the device according to the invention, the integrated in the spring elements fragrances are released, and they can leave a subtle fragrance of a selected aroma on request. A special equipment for the spacers and spacer fabric used according to the invention prevents the formation and nesting of dangerous molds and thus restricts the food source of pests, for example the house dust mite.

Der erste Abstandskörper kann alternativ auch aus einem sogenannten Schnittschaummaterial hergestellt werden. Dies ist in verschiedenen Anwendungsfällen ein bevorzugter Materialstoff. Die sogenannten Seitenriegel 20 werden vorzugsweise aus einem Kaltschaummaterial hergestellt. Das Abstandsgewirk 10' bzw. 12 ist unter dem Begriff "Dry Mesh" als waschbares Abstandsgewirk auf dem Markt erhältlich.The first spacer body may alternatively be made of a so-called cut foam material. This is a preferred material material in various applications. The so-called side bars 20 are preferably made of a cold foam material. The spacer fabric 10 'or 12 is available on the market under the term "dry mesh" as a washable spacer fabric.

Es hat als vorteilhafte Einstellung erwiesen, das Dickenverhältnis zwischen dem ersten und zweiten Abstandskörper etwa mit 4:1 zu wählen. Hierbei hat sich der höchste Komfortgrad gezeigt. Wie bereits oben angesprochen, können die Federelemente bzw. deren Härtegrad (gemessen in Shore-Härte) je nach Gewicht der Person, für welche das diskutierte Sitzmöbel vorgesehen ist, eingestellt werden. Daneben kann durch individuelle Auswahl von Federelementen eine gezielte Zonenlüftung und auch eine Kompensation von lokalen Belastungsspitzen erreicht werden.It has proved to be an advantageous setting to choose the thickness ratio between the first and second spacer body about 4: 1. This has shown the highest degree of comfort. As already mentioned above, the spring elements or their degree of hardness (measured in Shore hardness) depending on the weight of the person for whom the discussed seating is provided, can be adjusted. In addition, a targeted zone ventilation and also a compensation of local load peaks can be achieved by individual selection of spring elements.

Der Einsatz der erfindungsgemäßen Vorrichtung ist gleichermaßen in Sitzmöbeln oder Liegemöbeln. In der vorhergehenden Beschreibung der Erfindung wird der Einfachheit halber in der Regel von Sitzmöbeln gesprochen. Es wird betont, dass sich die Erfindung ebenso auf Liegemöbel wie auf Sitzmöbel bezieht und der Einsatz insbesondere im Care-Bereich in allen sinnvollen Anwendungsfällen sehr vorteilhaft möglich ist.The use of the device according to the invention is equally in seating or lying furniture. In the foregoing description of the invention is usually spoken for the sake of simplicity of seating. It is emphasized that the invention relates as well to reclining furniture as seating furniture and the use is particularly advantageous in all practical applications, especially in the care sector.
