Definitions

  • the present invention relates to a mattress divided into lying zones for a bed according to the preamble of patent claim 1.
  • Waterbeds have been an alternative to conventional mattresses for several years. Although these often have individual, independent chambers, they cannot offer optimal sleeping comfort either. The adjustment of the chambers to the optimal hardness turns out to be a lengthy procedure, since water has to be added or drained off in each case. In addition, water beds have an unpleasant side effect: depending on the filling quantity, the water vibrates with every movement with weak damping. These vibrations also affect the sleep of the bed neighbors. Further disadvantages of the water beds are listed below: Water beds have a relatively large weight. The water must be chemically treated regularly and changed sporadically to prevent algae formation. prevent. Because of its high thermal conductivity, the water must also always be heated to a temperature in the region of the body temperature. Finally, the waterbed must be treated carefully, since even the smallest leak can leak water and damage the furniture.
  • an air bed which has a plurality of pocket-shaped air chambers on the bed surface side, which are directly connected to one another and thus communicate with one another.
  • a complex control system is available to regulate the pressure in the air chambers.
  • the mattress according to the invention thus consists of a pneumatic multi-chamber system, the chambers being formed by individual carrier cells. This gives every part of the user's body optimal support.
  • the carrier cells communicate with a reservoir, a balancing arm. This ensures an almost constant air pressure in the support element when using the mattress. Since there are several support elements, it is now possible to cushion different support sections under the body with different firmness.
  • the mattress is also light and any leaks do not damage the mob leg or the room.
  • Figure 1 is a schematic representation of a mattress according to the invention from the side;
  • Figure 2 is an illustration of the same mattress in the view from above, ie on the lying side;
  • Figure 3 shows a section of the same mattress from the side
  • Figure 4 shows a section of another embodiment.
  • FIG. 1 to 3 show an embodiment variant of the mattress according to the invention.
  • the lying device is referred to here as a mattress, although it differs significantly from the conventional mattresses. Since they are how this is used in combination with known bed frames or bed systems, this term is used.
  • the mattress according to the invention is divided into different lying areas 4-7.
  • the number of lying areas depends on the embodiment.
  • a head-lying zone 4 a trunk-lying zone 5, a leg-lying zone 6 and a foot-lying zone 7 are distinguished.
  • These three lying zones 4-6 each consist of a carrier unit 1 and a compensation chamber 2.
  • the carrier unit 1 is arranged on the lying side, the compensation chamber 2 is located below it, that is to say on the bottom side.
  • Carrier unit 1 and compensation chamber 2 have approximately the same base area.
  • the compensation chamber 2 is, for example, a cavity made of a flexible plastic. In another embodiment, the cavity is made of a solid material, for example wood.
  • the carrier units 1 consist of a plurality of carrier cells 10. These carrier cells 10 are approximately cuboid, their rectangular outline having a short and a long side. Their dimensions are not essential to the invention. However, the smaller the carrier cells, the greater the number that can be arranged per square meter, which results in a finer division of the mattress.
  • the carrier cells 10 are made of a body-neutral, flexible plastic and with a gaseous one Medium, especially air or nitrogen, filled, their internal pressure is higher than atmospheric pressure. The pressure in the carrier cells 10 varies from carrier unit 1 to carrier unit 1.
  • Each carrier cell 10 is arranged on the compensation chamber 2 independently of its neighbors. It is preferably interchangeably connected to the compensation chamber 2. This allows easy replacement in the event of a leak.
  • the carrier cells 10 of a carrier unit 1 are arranged in a defined pattern to one another so that they can optimally support every point of the body.
  • the carrier cells 10 are arranged such that their short sides are parallel to the edge of the mattress.
  • the edges of the mattress have increased stability. This is necessary because the carrier cells do not have any adjacent neighboring cells on the edge on one side.
  • the same arrangement of the carrier cells 10 is preferably present on the edges of the lying zone on which the support units 1 adjoin one another as on the edges of the mattress.
  • the carrier cells 10 are not directly connected to one another, so that air gaps or air channels 8 are present between them.
  • the carrier cells 10 are preferably even spaced apart from one another so that the air channels 8 are continuous at least in the unloaded state.
  • Each support cell 10 is in a directly communicating connection with the associated compensation chambers 2 via passage openings 13.
  • Passage openings 13 are designed as a coupling element, which creates a sealing, form-fitting connection between support element 10 and compensation chamber 2.
  • a throttle is used in the communicating area between the carrier cell 10 and the compensation chamber 2.
  • the footrest zone 7 of the mattress is constructed differently from the lying zones 4-6 described above. On the lying side, it has a foam structure like the conventional mattresses, which is preferably made thinner. At the bottom, below the foam structure, there is a pressure chamber 3. This pressure chamber 3 communicates with the compensation chambers 2 by means of pressure regulating valves. This connection is not visible in the drawings. The pressure regulating valves work without external energy supply.
  • the entire mattress is provided with a mattress cover 9 made of fabric, so that the user cannot see any difference to conventional mattresses.
  • the support cells 10 can have a coating 12 in the form of a molton flocking on the lying side.
  • FIG. 1 It can also be seen in FIG. 1 that the individual lying zones 4-7 of the mattress can be brought to one another in different positions. This is made possible not least by the special arrangement of the support elements 10 on the edges of the lying zones.
  • a programmable automatic pressure change can be carried out in the carrier cells during the rest phase. These changes in pressure change the posture of the sleeping person without waking up.
  • print parameters can be saved or entered for the different lying areas according to a simple pictogram, for example hard, medium light.
  • the air channels between the carrier cells ensure that the mattress is ventilated and thus regulate the moisture balance. Since air is a good thermal insulator, there is no need for heating. On the contrary, the air filling ensures pleasant bed warmth.
  • the carrier cells are individually and interchangeably connected to the compensation chamber, only the defective carrier cell needs to be replaced if a leak occurs. Cleaning the mattress also turns out to be easier than with conventional mattresses because the mattress cover can be easily removed and washed.
  • FIG. 4 shows a modified variant of the carrier cells 10 '.
  • This has an L-shaped cross section, two adjacent support cells 10 'being arranged such that they are mirrored to one another in such a way that they form a common cuboid outline. It is obvious to the person skilled in the art that other forms of carrier cells are also possible. Arrangements of the carrier cell other than those shown in FIG. 2 are also possible.
  • the carrier cells are not arranged directly on the compensation chamber, but are only connected to it by hoses.
  • the carrier units can be brought to one another in different positions without the compensation chambers.
  • the compensation chambers can have an inflexible shape.
  • the pressure chamber is not arranged below the foot lying zone but below another lying zone.
  • the support cells in the edge zones of the mattress and the lying zones are not arranged with their short sides parallel to the edges but with their long sides.
  • these carrier cells show in in this case a higher overpressure than in the other arrangement.
  • These carrier cells are thus connected to at least one compensation chamber which is independent of the other carrier cells in the central region of the mattress.

Abstract

Un matelas pour lit comprend un système de chambres pneumatiques multiples formées par des cellules de soutien (10). Plusieurs chambres de soutien (10) sont rassemblées en une unité de soutien (1) qui forme avec une chambre sous-jacente de compensation (2) une zone de soutien (4-7). La chambre de compensation (2) est en communication avec les cellules individuelles de soutien (10) de façon à compenser la pression lorsqu'une charge s'exerce sur celles-ci. La commande et la régulation de la pression sont assurées par une chambre de compression (3) située dans la zone de soutien (7) au niveau des pieds. Ce matelas rempli d'air assure un confort maximal pendant le sommeil, étant donné que chaque partie du corps est soutenue de façon appropriée et que la dureté de chaque zone de soutien (4-7) peut être réglée individuellement.
