Definitions

  • the invention relates to an air-permeable mattress with great lying comfort and low weight, comprising at least one air-filled pressure cushion, preferably used as a sleeping mattress, whose basic structure allows an especially favorable air circulation and thus a removal of humidity secreted by the person lying on the same and offers an especially great lying comfort, whose pressure hardness is adjusted to the body zones and can be adjusted individually to the requirements of the person lying on the same, even when the needs are subjected to individual fluctuations or changes such as in the case of being bedridden for a prolonged period after illness or accident, and which further has a low weight and is completely free from metallic components.
  • New requirements are met by industry with new embodiments. They are capable however of always covering only individual requirements, but are unable to fulfill all relevant needs.
  • FIG. 1 For purposes of air pump. 1 093 739 A1
  • FIG. 1 For purposes of electric air pump.
  • FIG. 1 For embodiments with six air chambers or with 10 air chambers such as the mattress system designated as “air touch” round off these mattress systems.
  • the fundamental structure of the mattresses is principally disadvantageous in all these systems, which is characterized in that these air chambers assume in total virtually the entire lying area and thus an air circulation and a removal of secreted bodily humidity of the lying person is not possible through the mattress.
  • a further disadvantage relates to the use of metallic components, electronics, electrically operated air pumps and display devices.
  • a further known embodiment of a mattress with air chambers consists of a single air chamber whose filling is achieved with a special manually actuated air pump integrated in the bordering of the mattress and is actuated under load as a result of a displacement of the body weight.
  • the air pressure built up in the air chamber can be changed by means of a continuously adjustable valve.
  • Further embodiments relate to foam core mattresses where it is tried, through a combination of different patterns and variants in the foamed materials with different degrees of hardness, to achieve different pressure resistances in the individual lying regions.
  • a sufficient air circulation and removal of secreted body humidity is only possible to an only very limited extent in closed foam core mattresses, and the lying comfort and the cushioning behavior cannot be changed.
  • U.S. Pat. No. 6,487,739 B1 shows a multi-layer mattress which comprises an air cushion layer with a plurality of so-called “air cells” according to FIG. 1 for example.
  • the air circulation of this mattress is produced with a special air pump and occurs via the free intermediate spaces between the supporting air chambers.
  • an airing from the upper side to the lower side of the mattress is missing because the same would be interrupted by layers situated below in the embodiment according to U.S. Pat. No. 6,487,739 B1.
  • the mattress does not comprise a foam core.
  • EP 0 453 363 A1 discloses a mattress with spring elements and air chamber elements which each extend over one half in the central region of a double-bed mattress. The two lying sides can be brought to a different filling pressure and the lying comfort can be adjusted individually.
  • the mattress does not comprise a foam core however.
  • CH 687 806 A5 It is known from CH 687 806 A5 to provide a plurality of different individual chambers in a mattress, which chambers comprise at least one compensation chamber on the floor side.
  • the carrier cells can be filled with a gaseous medium and communicate with the compensation chamber via through holes (cf. FIG. 3 of CH 687.806 A5).
  • the mattress neither comprises a foam core nor the required airing which is directed from the upper side to the lower side of the mattress.
  • p A mattress is finally known from U.S. Pat. No. 5,907,878 A which consists of a plurality of air spring elements which are joined by means of an air-tight carrier layer.
  • the air-tight carrier layers prevent air permeability transversally through the mattress.
  • there is no foam core which should exert a carrying and supporting function.
  • the mattress consists of a combination of a foam core and air-filled pressure cushion(s), which are either arranged in openings of the foam core or enclose the same, and that for removing humidity through holes are provided in the foam core and/or in the pressure cushions.
  • the mattress in accordance with the invention thus consists of a foam core which is provided with a plurality of bore holes which penetrate the thickness of the mattress, with said bore holes being filled with air chambers or pressure cushions which can again be configured as hollow bodies and can be joined with each other by means of transversal connections in such a way that air can be exchanged in an unhindered manner in this system of air chambers.
  • air chambers or pressure cushions which can again be configured as hollow bodies and can be joined with each other by means of transversal connections in such a way that air can be exchanged in an unhindered manner in this system of air chambers.
  • These air chambers are joined with each other in zones (preferably three to seven zones), so that different pressures adjusted to the body zones can be built up.
  • a special air valve is provided for each of the zones, with the help of which the pressure in the air chambers can be limited individually.
  • a special apparatus is integrated which is configured as a pneumatic pump, with the help of which leakage losses by escaping air can be compensated and an increase in the pressure in the system can be made.
  • a pressure relief valve prevents any bursting of the air chambers in the case of an inadvertent overloading of the system.
  • the entire surface of the basic body of the foamed material including the surface of the through holes is covered with a layer of air-impermeable material.
  • An especially large air chamber is thus formed which is filled with foam material.
  • the air chamber and the foam material are compressed under load, the volume in the air chamber is reduced and a higher pressure level is built up. After relaxing, the foam material assumes its original shape again. The volume in the air chamber is enlarged again and the increased pressure degrades.
  • Any leaked air can automatically be refilled again (sucked in) by means of a special valve, which is configured as a non-return valve, when the air chamber assumes the maximum volume again and a negative pressure is produced in the interior as a result of a preceding air loss and ambient air with a higher pressure level flows through the valve into the interior until an approximate pressure balance is achieved.
  • a special valve which is configured as a non-return valve
  • the upper side of the mattress is provided with a support layer made of a material which can transport humidity especially well and is made of an antibacterial material.
  • the bottom side of the mattress consists of a layer which is especially air-permeable. Side elements made of a foam material with a higher pressure hardness are provided on the side, so that persons are able to support themselves better on the side if necessary.
  • the pressure behavior and the individual pressure distribution are relevant for the lying comfort, in addition to the capability of unhindered air circulation in the mattress.

  • the outside diameter D corresponds to the diameter of the opening 1 d in the mattress core 1 .
  • the inner opening 6 is provided for the air circulation.
  • FIG. 5 In a further embodiment of a pressure cushion according to FIG. 5 , additional openings 6 according to FIG. 10 are required for the air circulation 6 a in the mattress core.
  • the pressure cushions 5 are configured as solid cylinders in this embodiment. The diameter and the height correspond to the embodiments according to FIG. 4 and FIG. 6 .

  • the foam core 1 of the mattress is configured in an especially preferred embodiment in a manner consisting of several parts, preferably two parts.
  • the mattress core consists of two layers of foam material 1 ′, 1 ′′ of different hardness, with the bottom layer 1 ′′ preferably consisting of a foam material of higher hardness.
  • the cushioning properties and the lying comfort can thus be further influenced in a positive manner.
  • a further especially preferred embodiment of a combined foam-material and pressure-cushion mattress is composed in its entirety of a single pressure cushion or air chamber 5 , or of a pressure cushion or air chamber 5 for each zone.
  • the mattress structure consists of the mattress core 1 made of foam material which is provided with a plurality of openings 6 for the air circulation 6 a and an air-tight cover 10 made of film material for example, with the entire surface being covered in an air-tight manner with this cover, which also includes the walls of the opening 6 .
  • the mattress core must fulfill two tasks, on the one hand to support the overall pressure resistance of the mattress and on the other hand to compensate the deformation of the mattress again after a pressure load and to bring the air-tight cover 10 back to its original shape again at the same time and to increase the volume in this process.
  • Under the pressure load the volume of the air-tight cover forming a pressure cushion or air chamber 5 is reduced and the internal pressure is increased.
  • air-permeable foam cylinders 11 are provided for a modified embodiment, which cylinders are pushed into the through holes and fill a large part of the volume of the through hole 6 . Leakage losses are compensated after the expansion of the mattress by means of a non-return valve.

  • FIG. 12 shows an embodiment with five zones A 1 , C 1 , B, C 2 , A 2 and three pressure control devices. Leakage losses are compensated by means of an integrated air pump 12 .
  • This air pump is preferably integrated in the base of the mattress and, after a shift of weight of the person lying on the mattress, pumps under load a compressed air volume from the pump body into the pressure cushions or air chambers 5 up to the preset maximum pressure via air lines 15 through pressure control valve 14 a , 14 b , 14 c in the controller unit 13 .

  • Several pressure cushions/air chambers 5 are arranged transversally to the longitudinal axis of the mattress and parallel to the lying surface in openings 1 d of the mattress core 1 . They are configured as solid cylinders.
  • There is a defined intermediate space between adjacent pressure cushions/air chambers 5 which intermediate space allows an air circulation through the thickness of the mattress.
  • This air circulation is achieved on the one hand by the air-permeable foam material of the mattress core and can be supported by additional openings 6 which penetrate the mattress through its thickness.
  • the natural air circulation and the transport of humidity are supported by additional openings 6 a which are arranged parallel to the lying surface and which penetrate the width of the mattress.
  • the transversal pressure cushions/air chambers 5 can be subjected to different pressures and can be subdivided into several zones. Three, six or seven zones can be appropriately distinguished depending on the subdivision. It has proven to be especially appropriate to provide a middle zone D with a higher pressure resistance as lordosis support, two especially soft zones C 1 and C 2 for the shoulder and knee region, two zones of medium hardness B 1 and B 2 for the trunk and pelvic region, and two further zones A 1 and A 2 for the head and foot region.
  • the individual pressures can be adjusted individually by the lying person by means of simple, preferably metal-free control valves. The compensation of leakage losses and pressure increases are possible by means of an air accumulator which is filled automatically in case of any major shifting of weight.
  • the application thus substantially comprises the following main variants and sub-variants:
  • Double mattresses according to FIG. 15 are principally composed of individual mattresses 1 and glued together by means of special connecting elements 15 a , 15 b , such that a glued connection over a large surface with shearing strain is enabled and only a small remaining surface remains as a blunt glued point 15 c which only needs to fulfill subordinate strength requirements.
  • the main stress forces during the transport or during a usual load are absorbed by the connecting elements under shearing strain.
  • the same embodiments are provided for double mattresses as for single mattresses. Individual lying comfort is guaranteed by means of pressure control valves provided for each side of the mattress.
