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 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
  • a 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
  • the 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
  • an open-pore plastic foam preferably a polyurethane foam
  • 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
  • the superabsorber is polymerized directly onto the side of the outer coating facing away from the user.
  • 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
