Definitions
- the present invention relates to a cushion of a seat or a piece of reclining furniture with a desorbing moisture storage, which is preferably arranged as a layer insert with a hydrophilic character between the cover of the cushion and the cushion core and releases the moisture absorbed by the user back into the room air.
- Upholstery cores are often made of plastic, which are not naturally hydrophilic, so that an unpleasant build-up of moisture forms between the upholstery and the body surface of the seated person coming into contact with it, as a result of inadequate moisture dissipation. It is well known that comfort can be significantly improved by removing such moisture and avoiding a moisture build-up. It is particularly desirable to improve the seating climate on cushions that are used for long periods without interruption, such as Office chairs, motor vehicle seats and seats in long-distance transportation.
- DE 41 27 337 A1 additionally teaches superabsorbent polymers for the hydrophilic layer, ie to use linear, water-soluble or crosslinked, water-swellable macromolecular substances. It is stated as particularly expedient to delimit the hydrophilic layer towards the user of the seat by means of a moisture-permeable, hydrophobic layer and to provide ventilation on the back of the hydrophilic layer
- the granulate of the superabsorbent adheres to the carrier material only to a limited extent, so that there is a risk of migration of the granulate with an uneven distribution under load
- the object of the invention is to propose a hydrophilic layer of this type, where the disadvantages mentioned do not occur Manufacture of a cushion with a desorbing moisture store should be reduced and overall more cost-efficient
- the hydrophilic layer is formed from a carrier material known per se, which consists of an individual mesh onto which a superabsorber is directly polymerized.
- the fiber mesh is either directly the outer covering of the cushion or an insert that is inserted into the cushion separately or with The superabsorber is applied, for example, by spraying it onto the carrier material and subsequent polymerisation process.
- the individual fibers of the carrier material are coated with quasi-absorber
- a carrier material coated in this way with a superabsorber can be cut to size using conventional systems without any problems.
- the pre-cut sections can be inserted into the upholstery, preferably between serene cover and the foamed upholstery core Even with maximum saturation with moisture, the superabsorber in the gelled state keeps its connection to the fibers by wrapping it.
- Another advantage is a spatially more favorable distribution of the superabsorber than wrapping the load-bearing fibers with a substantially enlarged absorbent surface
- an open-pore plastic foam can also be used. Schhesshch can do without a separate carrier material and look at the superabsorbent itself, which then forms the hydrophilic layer in this configuration
- an upholstery consists of a foamed plastic core and an outer covering of textile material, if necessary, also leather.
- the upholstery is usually divided into two parts, namely into an upholstery for the horizontal sitting or lying level - to accommodate the user's buttocks or his entire body reclining posture - and in a cushion for the vertical level as a backrest
- the hydrophilic layer according to the invention is suitable for both levels, ie for seats in the form of stools, chairs, armchairs, banks, floor cushions and vehicle seats as well as for couches, i.e. sofas, beds and deckchairs

- the coating immediately forms the fibrous carrier material for the hydrophilic layer
- Variant I is based on the use of a fibrous or foamed carrier material, which is coated with the superabsorber.
- no actual carrier material is used for the superabsorber can be implemented here analogously, ie inserting a hydrophilic layer foamed solely from super absorber into the upholstery or laminating this layer directly or indirectly onto the outer coating.
- the moisture that a user releases at the contact surfaces with the cushion diffuses through the coating and is absorbed by the hydrophilic layer, which acts as a desorbing moisture store, until its saturation has been reached.
- the body-near moisture of the user is removed from his clothing or bare skin surface and the uncomfortable feeling of sweaty moisture is avoided.
- the hydrophilic layer gradually releases the absorbed moisture into the ambient air
- the release of moisture from the hydrophilic layer can also be achieved if the user lingers on the upholstery, but free spaces are created in the upholstery, via which circulating room air can reach the hydrophilic layer

Abstract
According to the invention, the padding of a seat or a reclining piece of furniture is provided with a desorbent moisture accumulator in the form of a hydrophilic layer which absorbs the bodily moisture from the user in a reversible manner. A known chemical superabsorber is used to form the hydrophilic layer. Said hydrophilic layer consists of an interwoven support material containing individual fibres, or an open-pored plastic foam and the superabsorber which is polymerised onto the support material. The fibres of the interwoven material are thus at least proportionally coated by the superabsorber. As an alternative, the hydrophilic layer can also consist solely of a foamed superabsorber. The specific advantages of this padding are improved seating comfort and the ability of the superabsorber to remain attached to the support material, even at a high level of moisture saturation, in a gelled state. In addition, a spatially more favourable distribution is achieved, providing a substantially enlarged absorbent surface.
Description
Polster eines Sitzes oder eines Liegemöbeis mit einem desorbierenden FeuchtiαkeitsspeicherUpholstery of a seat or a lounger with a desorbing moisture storage
Anwendungsgebiet der Erfindung Die vorliegende Erfindung betrifft ein Polster eines Sitzes oder eines Liegemöbels mit einem desorbierenden Feuchtigkeitsspeicher, welcher vorzugsweise als Schichteinlage mit hydrophilem Charakter zwischen dem Bezug des Polsters und dem Polsterkern angeordnet ist und die vom Benutzer aufgenommene Feuchtigkeit wieder in die Raumluft abgibt. Polsterkerne jedoch bestehen oft- mals aus Kunststoff, die von Natur aus nicht hydrophil sind, so dass sich ein unangenehmer Feuchtigkeitsstau zwischen dem Polster und der mit diesem in Kontakt kommenden Körperfläche der sitzenden Person, infolge unzureichender Feuchtigkeitsabfuhr, bildet. Es ist hinlänglich bekannt, dass mit dem Abführen derartiger Feuchtigkeit und Vermeidung eines Feuchtigkeitsstaus der Komfort wesentlich verbessert werden kann. Besonders wünschenswert ist eine Verbesserung des Sitzklimas auf Polstern, die ohne Unterbrechung längere Zeitspannen benutzt werden, wie z.B. Bürostühle, Kraftfahrzeugsitze und Sitze in Verkehrsmitteln für Langstrecken.Field of application of the invention The present invention relates to a cushion of a seat or a piece of reclining furniture with a desorbing moisture storage, which is preferably arranged as a layer insert with a hydrophilic character between the cover of the cushion and the cushion core and releases the moisture absorbed by the user back into the room air. Upholstery cores, however, are often made of plastic, which are not naturally hydrophilic, so that an unpleasant build-up of moisture forms between the upholstery and the body surface of the seated person coming into contact with it, as a result of inadequate moisture dissipation. It is well known that comfort can be significantly improved by removing such moisture and avoiding a moisture build-up. It is particularly desirable to improve the seating climate on cushions that are used for long periods without interruption, such as Office chairs, motor vehicle seats and seats in long-distance transportation.
Stand der TechnikState of the art
Gemäss der EP 0 126 798 B1 wurde zunächst vorgeschlagen, die Abfuhr sich sammelnder Feuchtigkeit durch Anordnung einer Wasserdampf durchlässigen Matte auf der dem Benutzer zugewandten Fläche des Schaumstoffkerns zu begünstigen, wobei im Schaumstoffkern Kanäle zum Ableiten der Feuchtigkeit vor- gesehen sind. Diese Kanäle sollen sich bei Kompression durch die Last des Benutzers nicht gänzlich verengen. Als Wasserdampf durchlässige Matte, die von einem äusseren Überzugsstoff überspannt ist, wird ein Vlies mit hydrophilem Binder eingesetzt. Das Vlies soll sowohl einen Anteil Feuchtigkeit speichern können als auch bei Sättigung Feuchtigkeit durchlassend ableiten.According to EP 0 126 798 B1, it was initially proposed to promote the removal of moisture that accumulates by arranging a mat that is permeable to water vapor on the surface of the foam core that faces the user, channels in the foam core being provided for draining off the moisture. These channels should not be narrowed completely when compressed by the load of the user. A nonwoven with a hydrophilic binder is used as the water vapor permeable mat, which is covered by an outer covering material. The fleece is said to both be able to store a portion of moisture and also to let moisture through when saturated.
In den Patentpublikationen DE 36 09 095 C2, DE 40 01 207 A1 und der DE 197 26 810 C1 wird zur intensiveren Feuchtigkeitsabfuhr ergänzend vorgeschlagen, die den Schaumstoffkern aufgebrachte Vliesschicht zwangsweise zu belüften
und mit einer Heizung zu kombinieren Die Vliesschicht enthalt ein hydrophiles faser- und/oder pulverformiges AbsorbtionsmateπalIn the patent publications DE 36 09 095 C2, DE 40 01 207 A1 and DE 197 26 810 C1 it is additionally proposed for more intensive moisture removal that the nonwoven layer applied to the foam core is forced to be ventilated and to combine with a heater The fleece layer contains a hydrophilic fiber and / or powdery Absorbtionsmateπal
Aus der DE 40 34 920 A1 ist bekannt, die hydrophilen Schichten für Sitze aus kovalent vernetzten Copolymeren zu bilden, welche in verschiedenen Ausfuhrungsformen zum Einsatz kommen Erwähnt ist, das hydrophile Copolymer in Teilchenform in offenporigen Schaumstoff einzuschaumen oder zwischen Vlies- schichten einzustreuen und durch Kleben oder Einnahen in Taschen zu fixieren Damit soll eine ungleichmassige Verteilung des Copolymers vermieden werden Ferner ist angegeben, aus dem Copolymer die flussige Komponente zu entfernen, um eine Folie oder Watte herzustellen, und in dieser Form zwischen den Schaumstoffkern und den ausseren Sitzbezug anzuordnen, z B in ein Vlies einzuwebenFrom DE 40 34 920 A1 it is known to form the hydrophilic layers for seats from covalently cross-linked copolymers, which are used in various embodiments, to foam the hydrophilic copolymer in particle form into open-cell foam or to sprinkle it between non-woven layers and by gluing or to fix the seams in pockets. This is to avoid an uneven distribution of the copolymer. It is also stated to remove the liquid component from the copolymer in order to produce a film or wadding and to arrange it in this form between the foam core and the outer seat cover, for example to be woven into a fleece
Die DE 41 27 337 A1 lehrt ergänzend für die hydrophile Schicht superabsorbierende Polymere, d h lineare, wasserlösliche oder vernetzte, wasserquellbare makromolekulare Stoffe zu verwenden Als besonders zweckmassig wird angegeben, die hydrophile Schicht zum Benutzer des Sitzes hingewandt mittels einer die Feuchtigkeit durchlassigen, hydrophoben Schicht abzugrenzen und auf der Ruckseite der hydrophilen Schicht eine Belüftung vorzusehenDE 41 27 337 A1 additionally teaches superabsorbent polymers for the hydrophilic layer, ie to use linear, water-soluble or crosslinked, water-swellable macromolecular substances. It is stated as particularly expedient to delimit the hydrophilic layer towards the user of the seat by means of a moisture-permeable, hydrophobic layer and to provide ventilation on the back of the hydrophilic layer
In der DE 198 09 156 A1 wird beschrieben, die hydrophile Schicht aus drei zusammenhangenden Schichten aufzubauen Hierbei sollen die zwei Aussenschichten, zumindest die zum Benutzer des Sitzes hingewandte Aussenschicht, Feuchte durchlassig sein Zwischen den Aussenschichten liegt als Abstandsge- wirk eine Tragerschicht aus losen, ineinander gekrauselten Fasern, in denen die Absorberpartikel gehalten werdenDE 198 09 156 A1 describes how to build up the hydrophilic layer from three coherent layers. Here, the two outer layers, at least the outer layer facing the user of the seat, should be permeable to moisture. Between the outer layers there is a support layer made of loose, one inside the other as a spacing effect crimped fibers in which the absorber particles are held
Der insoweit vorbekannte Stand der Technik weist folgende Nachteile auf - Das Fixieren von granulatformigem Superabsorber auf oder in einem Trager- matenal durch Einweben, Einnahen oder Kleben ist relativ arbeitsintensiv und man benotigt hierzu Vorrichtungen und Maschinen, um Einzelteile herzustellen
- Hergestellte Konfektionsteile mit eingearbeitetem Superabsorber können nachträglich nicht mehr zugeschnitten werden da ansonsten Granulat aus dem beschnittenen Konfektionsteil herausrieseln wurdeThe previously known prior art has the following disadvantages: Fixing granular superabsorbent onto or in a carrier material by weaving, sewing or gluing is relatively labor-intensive and devices and machines are required to produce individual parts - Manufactured parts with integrated superabsorbent can no longer be cut to size, otherwise granules would trickle out of the cut part
- Das Einarbeiten des Superabsorbers durch z B Einweben, Einnahen oder Kleben in Polstermateπal, bedingt eine begrenzt offen hegende Oberflache- The incorporation of the superabsorbent by, for example, weaving, sewing or gluing in upholstery material requires a limited open surface
- Das Granulat des Superabsorbers haftet nur bedingt am Tragermaterial, so dass unter Belastung die Gefahr der Migration des Granulats mit ungleich- massiger Verteilung besteht- The granulate of the superabsorbent adheres to the carrier material only to a limited extent, so that there is a risk of migration of the granulate with an uneven distribution under load

Aufgabe der ErfindungObject of the invention
Angesichts der vorgenannten Nachteile beim bisher praktizierten Einbringen von Superabsorbern in hydrohpile Schichten, die in Polstern zur Abfuhr von vom Benutzer stammenden Feuchtigkeit eingefugt werden, liegt der Erfindung die Aufgabe zugrunde, eine derart aufgebaute hydrophile Schicht vorzuschlagen, wo die erwähnten Nachteile nicht auftreten Der Fertigungsaufwand beim Herstellen eines Polsters mit einem desorbierenden Feuchtigkeitsspeicher soll sich vermin- dem und insgesamt kosteneffizienter werdenIn view of the above-mentioned disadvantages in the introduction of superabsorbers into hydrophilic layers, which are inserted into cushions for removing moisture originating from the user, the object of the invention is to propose a hydrophilic layer of this type, where the disadvantages mentioned do not occur Manufacture of a cushion with a desorbing moisture store should be reduced and overall more cost-efficient
Übersicht über die ErfindungOverview of the invention
Die hydrophile Schicht wird aus einem an sich bekannten Tragermateπal, gebildet, die aus einem Geflecht einzelner besteht, auf das ein Superabsorber direkt aufpolymeπsiert ist Das Fasergeflecht ist entweder direkt der aussere Überzug des Polsters oder eine Einlage, die in das Polster separat eingefugt oder mit dem Überzug verbunden wird Das Aufbringen des Superabsorbers geschieht z B durch Aufsprühen auf das Tragermaterial und anschhessenden Polymensa- tionsprozess Die einzelnen Fasern des Tragermaterials sind mit Superabsorber beschichtet, quasi umhülltThe hydrophilic layer is formed from a carrier material known per se, which consists of an individual mesh onto which a superabsorber is directly polymerized. The fiber mesh is either directly the outer covering of the cushion or an insert that is inserted into the cushion separately or with The superabsorber is applied, for example, by spraying it onto the carrier material and subsequent polymerisation process. The individual fibers of the carrier material are coated with quasi-absorber
Ein so mit einem Superabsorber beschichtetes Tragermaterial kann problemlos auf herkömmlichen Anlagen zugeschnitten werden Die konfektionierten Zuschnitte lassen sich in das Polster einfugen, vorzugsweise zwischen den aus-
seren Überzug und den geschäumten Polsterkern Auch bei maximaler Sättigung mit Feuchtigkeit behalt der Superabsorber im gelierten Zustand durch die Umhüllung der Fasern seine Verbindung zu diesen Als weiterer Vorteil ergibt sich eine räumlich gunstigere Verteilung des Superabsorbers als Umhüllung der tragenden Fasern mit einer wesentlich vergrosserten saugfahigen OberflacheA carrier material coated in this way with a superabsorber can be cut to size using conventional systems without any problems. The pre-cut sections can be inserted into the upholstery, preferably between serene cover and the foamed upholstery core Even with maximum saturation with moisture, the superabsorber in the gelled state keeps its connection to the fibers by wrapping it.Another advantage is a spatially more favorable distribution of the superabsorber than wrapping the load-bearing fibers with a substantially enlarged absorbent surface
Als Alternative zum vliesartigen Tragermateπal kann man dafür auch einen offenporigen Kunststoffschaum einsetzen Schhesshch ist es möglich, auf ein separates Tragermatenal zu verzichten und den Superabsorber selbst zu schau- men der dann in dieser Konfiguration die hydrophile Schicht bildetAs an alternative to the fleece-like carrier material, an open-pore plastic foam can also be used. Schhesshch can do without a separate carrier material and look at the superabsorbent itself, which then forms the hydrophilic layer in this configuration
AusfuhrungsbeispielExemplary embodiment
Üblicherweise besteht ein Polster aus einem geschäumten Kunststoffkern und einem darüber gezogenem ausseren Überzug aus textilem Material, ggf auch Leder Das Polster ist zumeist zweigeteilt, nämlich in ein Polster für die horizontale Sitz- oder Liegeebene - zur Aufnahme des Gesasses des Benutzers bzw seines gesamten Korpers in liegender Haltung - und in ein Polster für die Vertikalebene als Ruckenlehne Die erfindungsgemasse hydrophile Schicht ist für beide Ebenen geeignet, d h für Sitze in Gestalt von Hockern, Stuhlen, Sesseln, Banken, Bodenkissen und Fahrzeugsitzen sowie für Liegemobel, also Sofas, Betten und LiegestuhleUsually, an upholstery consists of a foamed plastic core and an outer covering of textile material, if necessary, also leather.The upholstery is usually divided into two parts, namely into an upholstery for the horizontal sitting or lying level - to accommodate the user's buttocks or his entire body reclining posture - and in a cushion for the vertical level as a backrest The hydrophilic layer according to the invention is suitable for both levels, ie for seats in the form of stools, chairs, armchairs, banks, floor cushions and vehicle seats as well as for couches, i.e. sofas, beds and deckchairs
Der Aufbau der hydrophilen Schicht im Polster kann in zwei prinzipiellen Varianten erfolgen namhch mit oder ohne Tragermaterial Für die Anordnung der hydrophilen Schicht im Polster werden mehrere Untervarianten vorgeschlagenThe hydrophilic layer in the upholstery can be built up in two basic variants, with or without a carrier material. Several sub-variants are proposed for the arrangement of the hydrophilic layer in the upholstery
Variante I → Aufbau der hydrophilen Schicht mit TragermatenalVariant I → Structure of the hydrophilic layer with carrier material
Untervaπante AUntervaπante A
Zwischen dem Kern des Polsters, welcher vorzugsweise aus geschäumtem Kunststoff beschaffen ist, und einem ausseren Überzug, welcher Feuchtigkeit durchlaset aber nicht aufnimmt, wird eine hydrophile Schicht eingebracht Diese hydrophile Schicht besteht aus einem Vlies als Tragermatenal, auf dessen Fasern ein chemisch an sich bekannter Superabsorber aufpolymeπsiert wurde Vorzugsweise wird die erfindungsgemasse hydrophile Schicht in Form von Mat- ten hergestellt, so dass sich daraus die verschieden konfigurierten Schichteinia-
gen - z B für die Sitzflache und die Ruckenlehne eines Burostuhls - schneiden lassen Zwischen dem ausseren Überzug und der eingelegten hydrophilen Schicht kann eine hydrophobe Zwischenlage angeordnet seinA hydrophilic layer is inserted between the core of the cushion, which is preferably made of foamed plastic, and an outer coating, which does not let moisture through but does not absorb moisture The hydrophilic layer according to the invention is preferably produced in the form of mats, so that the differently configured layer integrations For example - for the seat and the back of an office chair - have it cut A hydrophobic intermediate layer can be arranged between the outer cover and the inserted hydrophilic layer
Untervaπante BSub-variant B
Das vhesformige Tragermaterial mit dem aufpolymeπsierten Superabsorber und der so entstandenen hydrophilen Beschichtung ist auf den ausseren Überzug für das Polster aufkaschiert Das Aufkaschieren auf den ausseren Überzug geschieht in aller Regel auf der dem Benutzer abgewandten SeiteThe V-shaped carrier material with the superabsorber, which has been polymerized on, and the resulting hydrophilic coating, is laminated onto the outer covering for the cushion. The laminating onto the outer covering usually takes place on the side facing away from the user
Untetvaπante CUntetvaπante C
Anstelle eines faserformigen Tragermaterials wird ein offenporiger Kunststoff- schaum, vorzugsweise eine Polyurethan-Schaum, verwendet, auf den der Superabsorber aufpolymeπsiert ist Eine so aufgebaute hydrophile Schicht lasst sich ebenfalls in das Polster zwischen Polsterkern und ausseren Überzug einfugen, eventuell unter Zwischenfugung einer hydrophoben Einlage Auch ist es möglich, die hydrophile Schicht mit einem Kunststoffschaum als Tragermatenal direkt oder indirekt auf den ausseren Überzug aufzu kaschierenInstead of a fibrous carrier material, an open-pore plastic foam, preferably a polyurethane foam, is used, onto which the superabsorber is polymerized. A hydrophilic layer constructed in this way can also be inserted into the cushion between the cushion core and the outer coating, possibly with the intermediate layer of a hydrophobic insert it is possible to laminate the hydrophilic layer directly or indirectly onto the outer coating with a plastic foam as the carrier material
Untervariante DSub variant D
In vereinfachter Weise ist der Superabsorber direkt auf die dem Benutzer abgewandte Seite des ausseren Überzugs aufpolymeπsiert Somit bildet der Überzug unmittelbar das faserformige Tragermatenal für die hydrophile SchichtIn a simplified manner, the superabsorber is polymerized directly onto the side of the outer coating facing away from the user. Thus, the coating immediately forms the fibrous carrier material for the hydrophilic layer
Variante II - Aufbau der hydrophilen Schicht ohne TragermatenalVariant II - Structure of the hydrophilic layer without carrier material
Die Variante I beruht auf der Benutzung eines faserformigen oder geschäumten Tragermateπals, das mit dem Superabsorber überzogen ist Bei der Variante II hingegen wird für den Superabsorber kein eigentliches Tragermatenal verwendet Der Superabsorber als solcher wird geschäumt und ergibt so die hydrophile Schicht Die Untetvaπanten A und B sind hier analog realisierbar, d h Einfugen einer allein aus Superabsorber geschäumten hydrophilen Schicht in das Polster oder Aufkaschieren dieser Schicht direkt bzw indirekt auf den ausseren Überzug
Die Feuchtigkeit, die ein Benutzer an den Koπtaktflachen mit dem Polster abgibt diffundiert durch den Überzug und wird von der hydrophilen Schicht, die als desorbierender Feuchtigkeitsspeicher wirkt, aufgenommen bis deren Sättigung erreicht wäre Damit wird die korpernahe Feuchtigkeit des Benutzers von seiner Kleidung oder blosser Hautoberflache abgeführt und das unangenehme Gefühl von geschwitzter Feuchtigkeit vermieden Wird das Polster vom Benutzer freigegeben, so dass Raumluft an die mit Feuchtigkeit beladenen Flachen der hydrophilen Schicht gelangt, tritt ein reversibler Prozess ein Durch den Überzug hindurch gibt die hydrophile Schicht die aufgenommene Feuchtigkeit sukzessive an die Umgebungsluft wieder ab Die Abgabe von Feuchtigkeit aus der hydrophilen Schicht lasst sich auch dann erreichen, wenn der Benutzer auf dem Polster verweilt, aber im Polster Freiflächen geschaffen sind, über die zirkulierende Raumluft an die hydrophile Schicht gelangen kann
Variant I is based on the use of a fibrous or foamed carrier material, which is coated with the superabsorber. In variant II, on the other hand, no actual carrier material is used for the superabsorber can be implemented here analogously, ie inserting a hydrophilic layer foamed solely from super absorber into the upholstery or laminating this layer directly or indirectly onto the outer coating The moisture that a user releases at the contact surfaces with the cushion diffuses through the coating and is absorbed by the hydrophilic layer, which acts as a desorbing moisture store, until its saturation has been reached. Thus, the body-near moisture of the user is removed from his clothing or bare skin surface and the uncomfortable feeling of sweaty moisture is avoided. If the cushion is released by the user so that room air reaches the moisture-laden areas of the hydrophilic layer, a reversible process occurs. Through the coating, the hydrophilic layer gradually releases the absorbed moisture into the ambient air The release of moisture from the hydrophilic layer can also be achieved if the user lingers on the upholstery, but free spaces are created in the upholstery, via which circulating room air can reach the hydrophilic layer
