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 as Layered insert with a hydrophilic character between the upholstery cover and the cushion core is arranged and the one recorded by the user Releases moisture back into the air.
- Upholstery cores often exist made of plastic, which are not naturally hydrophilic, so that one unpleasant moisture build-up between the cushion and the one with it Contact coming body area of the seated person, due to insufficient Moisture removal, forms. It is well known that with the Removing such moisture and avoiding moisture build-up Comfort can be improved significantly.
- One is particularly desirable Improvement of the seating climate on upholstery the longer without interruption Time periods are used, e.g. Office chairs, motor vehicle seats and seats in long-distance transportation.
- hydrophilic layers for seats are made of to form covalently cross-linked copolymers, which in various embodiments are used.
- the hydrophilic copolymer is mentioned in Foam particle shape in open-cell foam or between non-woven layers sprinkled in and fixed by gluing or sewing into pockets. This is to avoid an uneven distribution of the copolymer. It is also stated to remove the liquid component from the copolymer, to make a film or wadding, and in this form between the Arrange foam core and the outer seat cover, e.g. to be woven into a fleece.
- hydrophilic layer Polymers, i.e. linear, water-soluble or cross-linked, water-swellable to use macromolecular substances. It is stated as particularly expedient the hydrophilic layer is turned towards the user of the seat by means of a to delimit the moisture-permeable, hydrophobic layer and on the Ventilation must be provided on the back of the hydrophilic layer.
- the hydrophilic layer is formed from a carrier material known per se, which consists of a network of individual fibers onto which a superabsorbent directly is polymerized.
- the fiber braid is either directly the outer covering of the upholstery or an insert that is inserted into the upholstery separately or with the coating is connected.
- the super absorber is applied e.g. by spraying onto the carrier material and subsequent polymerization process.
- the individual fibers of the carrier material are made with super absorber coated, quasi enveloped.
- a carrier material coated in this way with a superabsorber can be used without problems can be cut on conventional systems.
- the ready-made cuts can be inserted into the upholstery, preferably between the outer ones Cover and the foamed upholstery core. Even at maximum saturation with moisture, the superabsorber keeps it gelled through the Wrapping the fibers its connection to them.
- Another advantage is there is a spatially more favorable distribution of the super absorber than wrapping the load-bearing fibers with a significantly larger absorbent surface.
- a cushion consists of a foamed plastic core and an outer cover made of textile material, possibly also leather.
- the cushion is usually divided into two, namely a cushion for the horizontal Sitting or lying level - to accommodate the user's buttocks or of his entire body in a lying position - and in a cushion for the vertical plane as a backrest.
- the hydrophilic layer according to the invention is for suitable for both levels, i.e. for seats in the form of stools, chairs, armchairs, Benches, floor cushions and vehicle seats as well as for couches, i.e. sofas, Beds and deck chairs.
- a hydrophilic layer is introduced between the core of the cushion, which is preferably made of foamed Plastic is procured, and an outer coating, which moisture lets through, but does not absorb.
- the hydrophilic layer consists of a fleece as the carrier material on the fibers a chemically known super absorber was polymerized.
- the hydrophilic layer according to the invention is preferably in the form of mats manufactured, so that the differently configured layered inserts - e.g. for the seat and back of an office chair - cut to let. Between the outer coating and the inserted hydrophilic Layer can be arranged a hydrophobic intermediate layer.
- the fleece-shaped carrier material with the superabsorber and polymerized on The resulting hydrophilic coating is for the outer coating the pad laminated. Laminating onto the outer coating happens usually on the side facing away from the user.

Description
- Das Fixieren von granulatförmigem Superabsorber auf oder in einem Trägermaterial durch Einweben, Einnähen oder Kleben ist relativ arbeitsintensiv und man benötigt 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 würde.
- Das Einarbeiten des Superabsorbers durch z.B. Einweben, Einnähen oder Kleben in Polstermaterial, bedingt eine begrenzt offen liegende Oberfläche
- Das Granulat des Superabsorbers haftet nur bedingt am Trägermaterial, so dass unter Belastung die Gefahr der Migration des Granulats mit ungleichmässiger Verteilung besteht.
- Bei höherer Feuchtigkeitsaufnahme geht das Granulat des Superabsorbers in einen geleeartigen Zustand über, so dass sich Klebverbindungen mit dem Trägermaterial lösen.
Claims (9)
- Polster eines Sitzes oder eines Liegemöbels mit einem desorbierenden Feuchtigkeitsspeicher in Form einer hydrophilen Schicht zur reversiblen Aufnahme von vom Benutzer stammenden Körperfeuchtigkeit, wobei zur Bildung der hydrophilen Schicht ein chemisch an sich bekannter Superabsorber eingesetzt wird, dadurch gekennzeichnet, dass die hydrophile Schicht besteht aus:einem Trägermaterial in Gestalt eines Geflechts mit einzelnen Fasern und dem auf das Trägermaterial aufpolymerisierten Superabsorber, wodurch die Fasern des Geflechts zumindest anteilig vom Superabsorber überzogen sind.
- Polster nach Anspruch 1, dadurch gekennzeichnet, dass die hydrophile Schicht zwischen einen geschäumten Kunststoffkern und einen äusseren, für Feuchte durchlässigen, aber an sich hydrophoben Überzug eingefügt ist.
- Polster nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass der Superabsorber vor seiner Polymerisation auf das Trägermaterial aufgesprüht oder im Tauchbadverfahren aufgebracht ist.
- Polster nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dassa) das mit dem Superabsorber versehene Trägermaterial die Form von Matten aufweist und sich komplementär zur Flächengeometrie des Polsters zuschneiden lässt; undb) die im Polster angeordnete hydrophile Schicht ein- oder mehrlagig ausgebildet ist.
- Polster nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass zwischen dem äusseren Überzug und der hydrophilen Schicht eine hydrophobe Schicht angeordnet ist.
- Polster nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass direkt der Überzug für das Polster, vorzugsweise dessen dem Benutzer abgewandte Seite, das Trägermaterial für den aufpolymerisierten Superabsorber ist.
