Innerhalb dieser Hülle befindet sich eine Schaumstoff-Ummantelung für eine in einer feuchtigkeitsundruchlässigen Umhüllung eingeschlossenen Einlage aus einem Material flüssiger bis pastöser Konsistenz, das unter der Einwirkung eines dem Gewicht des menschlichen oder tierischen Körpers entsprechenden Druckes (praktisch) nicht zusammendrückbar ist. Die Einlage lagert dabei auf einer unteren Auflagefläche, die aus dem unteren Teil der Schaumstoff-Ummantelung gebildet wird, auf.In WO 82/00578 A1 describes a pad for sitting or lying areas, those with a shell is provided, which has a fur cover as the upper edition. Within this shell There is a foam sheath for a trapped in a moisture-impermeable sheath Insert of a material liquid until pasty Consistency, which under the action of a human weight or animal body corresponding pressure (practically) is not compressible. The deposit is stored on a lower support surface, the is formed from the lower part of the foam sheath, on.
Nachteilig an der in der WO 82/00578 A1 beschriebenen Unterlage ist, dass Sie aufgrund Ihres Aufbaus eine große Bauhöhe aufweist.adversely to the document described in WO 82/00578 A1 is that you due to your construction a big one height having.
Von dieser Problemstellung ausgehend, liegt der Erfindung die Aufgabe zu Grunde, einen Formkörper mit geringer Bauhöhe so zu gestalten, dass er sich insbesondere für ein Sitzpolster verwenden lässt und hier zu einem hohen Sitzkomfort bei gegenüber her kömmlichen Sitzpolstern verringerter Bauhöhe führt und der sich generell für den Sitzmöbelbereich (Armauflagen, Rückenkissen, Nackenkissen) und insbesondere auch für den Fahrzeugbereich einsetzen lässt, bei denen eine Verringerung der Bauhöhe besonders vorteilhaft ist, da hierdurch unter dem Fahrzeugsitz ein höherer Einbauraum für technische Einbauten geschaffen werden kann.From Based on this problem, the invention is the task at the bottom, a molding with low height be designed so that he use in particular for a seat cushion lets and here to a high level of comfort in comparison with conventional seat cushions reduced Height leads and generally speaking for the seating area (armrests, Back cushions, Neck pillow) and in particular also for the vehicle sector leaves, where a reduction in height is particularly advantageous, as a result, under the vehicle seat, a higher installation space for technical installations can be created.
Diese Aufgabe wird gelöst durch einen gattungsgemäßen Formkörper, der sich dadurch auszeichnet, dass die Auflagefläche eine aus einem Polyurethan-Gel bestehende Gellage ist, die auf Ihrer Oberseite integrale, voneinander über Ausdehnungskanäle beabstandete Auflager aufweist, auf denen eine Polyurethan-Schaumstofflage aufliegt, deren Oberseite durch die obere Auflage abgedeckt ist.These Task is solved by a generic molding, the characterized in that the bearing surface of a polyurethane gel existing gel layer is integral on its top, spaced apart from one another via expansion channels Having supports bearing a polyurethane foam layer, the top of which is covered by the upper support.
Dabei ist es zweckmäßig, wenn die Auflage im Bereich der bei Belastung auftretenden Druckspitzen einen engeren Abstand voneinander aufweisen, wobei die Auflage vorzugsweise säulenförmig ausgebildet sein können.there it is useful if the support in the area of the pressure peaks occurring under load a closer distance from each other, wherein the support preferably formed columnar could be.
Aus Belüftungszwecken ist es vorteilhaft, wenn die obere Auflage ein Abstandsgewirk ist, das aus zwei durch Abstandsfäden miteinander verbundenen textilen Flächen besteht. Das an sich bekannte Abstandsgewirk setzt sich zusammen aus einer Warengrunde, einer Warenseite und aus diese miteinander verbindende Legebarren. Die Eigenschaften eines Abstandsgewirkes werden im Wesentlichen von den Bindungsstrukturen, also der Einbindung der Fäden in die Fläche, der Maschendichte sowie der Fadenstärke beeinflusst. Durch ihre 3D-Struktur bieten Abstandsgewirke viele technische Vorteile wie Luftdurchlässigkeit, geringes Gewicht, gutes Rückstellverhalten, Schockabsorption, Wärmezirkulation, Recyclingfähigkeit, Sortenreinheit und gute Verformbarkeit.Out ventilation purposes it is advantageous if the upper support is a spacer, that of two by spacer threads interconnected textile surfaces. The known Spacer knit consists of a goods reason, a Goods side and from these interconnecting guide bar. The Properties of a spacer knit are essentially determined by the binding structures, so the involvement of the threads in the Area, the mesh density and the thread strength influenced. Through her 3D structure, spacer fabrics offer many technical advantages such as air permeability, low weight, good resilience, Shock absorption, heat circulation, recyclability, Varietal purity and good ductility.
Hinsicht spezieller Ausführungsformen der Polyurethan-Schaumstofflage sowie ihrer Verbindung mit der Gellage wird auf die Gegenstände der Ansprüche 6 bis 10 verwiesen.respect special embodiments the polyurethane foam layer and its connection with the gel layer is on the objects the claims 6 to 10 referenced.
Erfindungsgemäß besteht die Gellage aus einem Polyurethan-Gel, dessen chemische Struktur aus langen Polymer-Fäden und nur wenigen Verkettungen ohne Verwendung zugesetzter Weichmacher bestehen kann.According to the invention the gel layer of a polyurethane gel, its chemical structure long polymer threads and consist of only a few links without the use of added plasticizers can.
Es ist aber möglich, dass für das Gel ein untervernetztes Polyurethan auf der Basis von Polyolen und Polyisocyanaten oder Polyethern und Polyisocyanaten eingesetzt wird.It but it is possible that for the gel is an undercrosslinked polyurethane based on polyols and Polyisocyanates or polyethers and polyisocyanates is used.
Erfindungsgemäß ist es zweckmäßig, wenn die Gelmassen mit Rohstoffen einer Isocyanat-Funktionalität der Polyolkomponente von mindestens 5,2 vorzugsweise von mindestens 6,5, insbesondere von mindestens 7,5 hergestellt werden.It is according to the invention expedient if the Gelled with raw materials of an isocyanate functionality of the polyol component of at least 5.2, preferably of at least 6.5, in particular of at least 7.5.
Dabei ist es vorteilhaft, wenn die Polyolkomponente zur Herstellung des Gels aus einem Gemisch aus
- a) einem oder mehreren Polyolen mit Hydroxylzahlen unter 1 12 und
- b) einem oder mehreren Polyolen mit Hydroxyzahlen im Bereich von 112 bis 600 besteht,
- a) one or more polyols having hydroxyl numbers below 1 12 and
- b) one or more polyols having hydroxyl numbers ranging from 112 to 600,
Als Alternativlösung kann vorgesehen sein, dass die Polyolkomponente zur Herstellung des Gels aus einem oder mehreren Polyolen mit einem Molekulargewicht zwischen 1000 und 12000 und einer OH-Zahl zwischen 20 und 1 12 besteht, wobei das Produkt der Funktionalitäten der polyurethanbildenden Komponenten mindestens 5 beträgt und die Isocyanat-Kennzahl zwischen 15 und 60 liegt.When alternative solution it can be provided that the polyol component for the preparation of the gel of one or more polyols having a molecular weight between 1000 and 12000 and an OH number between 20 and 1 12, the product of the functionalities of the polyurethane-forming Components is at least 5 and the isocyanate index is between 15 and 60.
Schließlich ist es vorteilhaft, wenn man als Isocyanate zur Gelherstellung solche der Formel Q (NCO) einsetzt, in der n für 2 bis 4 steht und Q einen aliphatischen Kohlenwasserstoffrest mit 8 bis 18 C-Atomen, einen cycloaliphatischen Kohlenwasserstoffrest mit 4 bis 15 C-Atomen, einen aromatischen Kohlenwasserstoffrest mit 6 bis 15 C-Atomen oder einen aralisphatischen Kohlenwasserstoffrest mit 8 bis 15 C-Atomen bedeutet, und wenn das Polyurethan mit Isocyanaten in reiner Form oder mit urethanisierten, allophanisierten, biurethisierten oder funktionell entsprechend modifizierten Isocyanaten hergestellt ist.Finally is it is advantageous if, as isocyanates for gel production such of the formula Q (NCO) in which n is 2 to 4 and Q is an aliphatic Hydrocarbon radical having 8 to 18 carbon atoms, a cycloaliphatic Hydrocarbon radical with 4 to 15 C atoms, an aromatic hydrocarbon radical with 6 to 15 carbon atoms or an aralisphatic hydrocarbon radical with 8 to 15 carbon atoms means, and when the polyurethane with isocyanates in pure form or with urethanised, allophanised, biuretted or is functionally prepared according to modified isocyanates.
Die
Die bekannten Polyol- und Isocyanatgemische weisen für die oben beispielhaft genannten Anwendungen stets den Nachteil des hohen Eigengewichtes und die damit verbundene hohe Wärmekapazität auf. Aufgrund des hohen Eigengewichtes von etwa 1,0 g/cm3 ist der Einsatz auf Anwednungen beschränkt, bei denen das Gewicht in Relation zu den hervorragenden druckverteilenden Eigenschaften eine untergeordnete Rolle spielt. Darüber hinaus kann die hohe Wärmekapazität des Polyurethan-Gels im direkten Körperkontakt als unangenehm empfunden werden, da Körperwärme zum Aufwärmen der jeweiligen Gelmassen deutlich wahrnehmbar dem Körper entzogen wird.The known polyol and isocyanate mixtures always have the disadvantage of the high own weight and the associated high heat capacity for the applications exemplified above. Due to the high weight of about 1.0 g / cm 3 , the use is limited to applications in which the weight plays a minor role in relation to the excellent pressure-distributing properties. In addition, the high heat capacity of the polyurethane gel in direct body contact can be perceived as unpleasant, since body heat to warm up the respective gel masses is clearly removed from the body.
In
der
Ein weiterer Nachteil der beschriebenen Polyurethan-Gele ist das Einsitzverhalten. Insbesondere beim ersten Kontakt wird ein Gel-Kissen häufig als hart empfunden, weil erst mit einer Zeitverzögerung das Gel in die gewünschte eine optimale Druckverteilung garantierende Position fließt bzw. geflossen ist.One Another disadvantage of the polyurethane gels described is the single seat behavior. Especially at the first contact, a gel pad is often considered hard felt, because only with a time delay, the gel in the desired one optimal position of the pressure guaranteeing or flowing flowed.
Eine Gelmasse, die eine deutliche Reduzierung des Gewichtes, der Wärmekapazität und des Einsitzkomforts unter Beibehaltung der typischen Geleigenschaften, wie z.B. der Aufnahme von Scherkräften möglich macht, bedeutet eine deutliche technische Verbesserung.A Gel mass, which significantly reduces the weight, the heat capacity and the Einsitzkomforts while retaining the typical gel properties, e.g. of the Absorption of shear forces possible makes a significant technical improvement.
Die für die erfindungsgemäß vorgesehene Gellage zu verwendenden Gelmassen sollten die vorstehend genannten Nachteile vermeiden und die typischen vorteilhaften Geleigenschaften mit einem niedrigen spezifischen Gewicht einer insgesamt niedrigeren Wärmeleitfähigkeit sowie guter Haltbarkeit und dauerhaft gleich bleibenden Gebrauchsmustereigenschaften verbinden. Es ist daher vorteilhaft, wenn die Gellage elastische Mikrohohlkugeln als Füllstoff enthält, wobei die Mikrohohlkugeln aus polymerem Material, vorzugsweise Polyolefin bestehen und mit einer Deckschicht aus einem anorganischen Material, vorzugsweise Calciumkarbonat, beschichtet sind.The for the Gellage provided according to the invention Gel masses to be used should have the disadvantages mentioned above avoid and the typical favorable gel properties with a low specific weight of an overall lower thermal conductivity as well as good durability and permanently consistent utility model properties connect. It is therefore advantageous if the gel layer is elastic Hollow microspheres as filler contains wherein the hollow microspheres of polymeric material, preferably polyolefin consist and with a cover layer of an inorganic material, preferably calcium carbonate coated.
Es ist vorteilhaft, wenn die Mikrohohlkugeln einen Durchmesser von 10 μm bis 150 μm besitzen, und wenn der Anteil der Mikrohohokugeln in dem Gelwerkstoff 0,1–10 Gew.-% beträgt.It is advantageous if the hollow microspheres have a diameter of 10 μm to Have 150 microns, and if the proportion of micro-spheres in the gel material is 0.1-10% by weight is.
Der Sitzkomfort lässt sich insgesamt noch dadurch verbessern, dass in der Gelmasse grobkörnige Feststoffteilchen verteilt sind, die aus Korkstückchen, Korkmehl, Holzstückchen, Holzspänen, Schaumstoffflocken, Styropor, Textilfasern oder Textilstücken bestehen, deren Durchmesser vorzugsweise zwischen 0,1 mm und 15 mm liegt.Of the Seating comfort leaves Overall, even better, that in the gel mass coarse-grained solid particles are distributed from cork pieces, Cork flour, pieces of wood, Wood shavings, foam flakes, Styrofoam, textile fibers or textile pieces consist whose diameter preferably between 0.1 mm and 15 mm.
Erfindungsgemäß wird der Einsitz-Komfort durch die obenliegende Polyurethan-Schaumstofflage wesentlich verbessert.According to the invention Single-seat comfort through the overhead polyurethane foam layer essential improved.
