Definitions

  • the invention relates to a cushion filled with gas, in particular filled with air.
  • Such pillows are well known. They are regularly inflatable pillows.
  • the disadvantage of these pillows is the dosage of the air filling. If the filling is too large, the pillow feels hard. If the cushion is insufficiently filled, the cushion will lie through, ie you can feel the surface under the cushion. There is always a wobble on conventional inflatable cushions, which affects the lying comfort. With increasing pillow size, the name changes from pillow to mattress. In the following this distinction is not made and the term "pillow" also includes mattresses.
  • Pillows are already known which are filled with air, gas, granules, liquid or other materials.
  • Air-filled pillows are also known, the air filling of which is adjustable before use. Every known air mattress is adjustable. From DE 29719434 pillows are also known from which the air filling can escape partially under load until the pillow has placed itself on a body in the desired manner.
  • pillows are known from GB-1035490 A with different chambers, the walls of which are permeable to air, so that air can escape from the loaded chambers into other chambers under load. When the cushions are relieved, the cushions are largely deformed again.
  • DE 69611701 A2 a pillow with several chambers is described, with differently used chambers being used in parallel. In the example, chambers with liquid filling are used, which are connected to one another in such a way that the liquid flows from one chamber into other chambers under chamber load. The same applies to the air filling of the chambers provided for the rest.
  • the invention is therefore based on the object of an air-filled or gas-filled cushion create that has a greater lying comfort.
  • the invention is based on that from the GB 1035490 A known concept.
  • the invention has recognized that compliance and Adaptation of the cushion areas to the user in the system is still not satisfactory Show results.
  • the feeling of comfort is correspondingly low.
  • the pillow has a main chamber, for example as a central chamber, which is provided with an air filling or a gas filling in the initial situation.
  • the central chamber is surrounded by a peripheral chamber.
  • the pillow wall between the two chambers is air-permeable or gas-permeable, so that when the pillow is used, the air or gas under body weight partially escapes from the central chamber into the peripheral chamber.
  • the air or gas permeability is explained below.
  • the pillow adapts to the surface by the escape of air or gas Body part very well.
  • the body part slowly sinks.
  • the air or gas flows from the central chamber into the peripheral chamber repressed. With each movement, a new adjustment takes place. That gives a high Comfort feeling.
  • the slow escape of the air filling from the central chamber into the peripheral chamber, as well as the backflow of air results in an additional feeling of comfort when the cushion is partially relieved or when the user changes position.
  • the dimensions of the chambers can be different or the same.
  • the connection of the chambers causes the self-regulating air distribution / migration of air.
  • a central or central chamber is preferably provided in the cushion, which is surrounded by an annular chamber.
  • the central chamber is the main chamber in this example. Both chambers experience a special volume behavior in the initial position before use. Without stress, an elastic filling, preferably in the main chamber, ensures that the main chamber is maximally expanded. In the closed system of both chambers, the main chamber only fills with air from the other chamber.
  • this is the annular chamber, the peripheral chamber.
  • the annular, peripheral chamber is partially or largely emptied. With a smaller volume of the annular, peripheral chamber, this chamber is practically completely emptied in the starting position.
  • the main chamber experiences a load which causes the main chamber to compress and escape from the main chamber into the annular peripheral chamber. For example, a volume ratio of 50:60 between the two chambers can result.
  • the system according to the invention can also be used on neck pillows, which Surround the user's neck in a horseshoe shape.
  • the peripheral Contribute chamber to support the main chamber as described above.
  • a setting of the air content is optionally found in the system according to the invention the user's body weight instead. This can make an attitude towards men, women and children are done.
  • the pillows of the invention are according to the Body weight hard with high body weight or soft with low body weight.
  • the system according to the invention can advantageously be used without adjustment Air exchange with the surrounding atmosphere.
  • the air or gas permeability is optionally achieved by perforating the Chamber wall and / or by an air or gas permeable textile Chamber wall and / or due to incomplete connection of foils from which the air or gas-permeable chamber wall is formed.
  • the desired one can be perforated Adjust air or gas permeability exactly.
  • the use of an air or gas-permeable textile is preferably of a certain desired size for the Exit flow from the central chamber.
  • the air or gas filling is preferably atmospheric in the unloaded state Print. Deviating from this, a slight overpressure can also be selected.
  • the pressure must in any case be relatively close to the atmospheric pressure, because that Pillow otherwise does not experience significant deformation during use and the feeling of comfort does not occur.
  • the right pressure can be achieved with just a few tries based on the feeling of comfort be determined.
  • the volume of the central chamber and the peripheral chamber is thus one on top of the other agreed that the user is not sagging. That too can be done with a few tries Reduction or enlargement of the peripheral chamber can be determined.
  • the cushion according to the invention also includes an airtight and waterproof cushion cover.
  • the cushion cover is preferably also elastic and stretchable. Suitable for such covers for example a plastic film.
  • a film made of polyurethane (PU) Application are e.g. with a thickness of 0.2 mm and a width of 150 cm available in any color.
  • plastics are also suitable for the film.
  • from multilayer films can be advantageous.
  • the individual layers can be different Take over functions, e.g. can a film with a high sealing effect on the outside with a soft film layer, e.g. a foam layer can be combined.
  • the film is at least up to 50 degrees Celsius, preferably up to 100 degrees Celsius temperature resistant.
  • Plastic films are also sensitive to cleaning agents and Disinfectant insensitive. There is also a mechanically very resistant one Plastics such as polypropylene used for high pressure cleaning and for others Washing processes are suitable and can be brushed.
  • the pillow according to the invention has hygienic advantages. There is no air or Moisture exchange with the environment takes place. This will cause bacteria and other Microorganisms prevented from settling in the pillow.
  • the central chamber preferably consists of two film sections which lie one on top of the other and are glued or welded together at the edge.
  • the welding or gluing can with filling included.
  • the filling is preferably carried out only after Prefabrication of the central chamber through an open filling opening, which after the Filling is closed.
  • the film sections can be perforated at the edge.
  • For perforating is suitable for Example a needle roller.
  • the perforation alone can provide the desired air passage cause so that the film sections are welded or glued all around the edge can.
  • the film sections can also only be provided with windows at the edge that pass through a welded or glued textile are closed.
  • All air passages or gas passages are designed in the opening width that the Filling a chamber is not carried out with the escaping gas. Is optional also the particle size of the filling chosen so large that the particles at the smaller opening be stopped for the escaping gas.
  • the peripheral chamber is optionally attached to the edge of the central chamber by two circumferential film tabs with their inner edge on the upper and lower film for the central chamber can be welded or glued on. Alternatively, this can be done after the central chamber has been completed. It is both possible to have one To weld or glue the film tabs to the central chamber and then to weld or glue the foil tabs together at the edge, as well Conversely, first glue the foil tabs together at the edge and then on to weld or glue the central chamber.
  • foil tab cutting instead of two foil tabs for the peripheral chamber, a single one can also be used Use foil tab cutting. This blank is then cut with the inner edge welded or glued to the finished central chamber. The outer edge is after that while leaving a sufficient margin for the peripheral chamber around the knocked around the outer edge of the central chamber and welded in place or glued to which otherwise the welding of the inner edge of the second film tab he follows.
  • the covering foil sections are first welded together to effect the central chamber and then the overlapping foil sections at the edge to weld together.
  • the overlapping film sections form with the Two-ply not just an additional sealing effect. They also contribute to the feeling of comfort at, because in the overlapping film sections a disturbing material impact between the Foils of the central chamber and the peripheral chamber is avoided.
  • the pillows of the invention are also manufactured so that initially Uniform parts emerge, both as a pillow top and as a pillow bottom Use the central or after the whole or part of it Form chamber and the peripheral chamber.
  • the plastic foils are welded together by heating the welding surfaces.
