Definitions

  • the invention relates to an anatomically designed Mattress on the basis of a one-piece connected Foam body of generally flat cuboid shape with two in the use position essentially main surfaces to be positioned horizontally, namely one Bottom face and one top face, still with two in the position of use essentially vertical transverse lateral surfaces, namely a transverse side surface close to the head and a transverse side surface near the foot, and continue with two essentially again in the position of use vertical long side surfaces, the top surface - in Viewed from above - on both sides of a vertical longitudinal median plane a hip-rest area, one Shoulder rest area, a head rest area and one Has leg-footrest area.
  • a mattress which is made of different latex Density is established.
  • the finished mattress has one thicker latex consisting of firmer central area and one Less dense latex existing softer edge area.
  • the Manufactured in such a way that the two latex materials in liquid state can be poured into a foam mold, which then at the same time vulcanized to the mattress.
  • With pens in the foam form an attempt is made to merge the differently dense latex materials to limit.
  • a certain confluence must be with regard to the structural strength of the mattress can be accepted can not be completely prevented by pens anyway.
  • AU-A-4 12 227 is one of several foam layers manufactured mattress known, with reference to a lower lying Cut out sections in the upper layer covering this are to provide a height profile adapted to the body of a user.
  • Foam layer parts can be inserted into the recesses with appropriate Dimensions are used that have a different density or have different strength.
  • the attachment of the layers and possibly the Layer pieces filling recesses are made by means of double-button-like Connecting elements (elements 14, Fig. 6).
  • From CH-A-493 241 is a foam mattress referred to as one piece known in which a rhomboid-shaped middle part made of foam better quality than triangular side parts, which are on the middle part are stuck.
  • an exercise and therapy pillow which in is substantially circular cylindrical.
  • Filling material such as foam rubber
  • a core of solid material such as Hard rubber, embedded.
  • the filling material including the one embedded in it
  • the core is sewn into a sleeve made of flexible material, such as fabric.
  • the Patent specification contains no information about the consistency or structure of the Filling material and the way in which the core is embedded in the filling material.
  • an object of the present invention is a mattress to provide with compressive stiffness properties with a view to Stabilized seating on the long sides of the mattress or / and Regarding the sleeping comfort of a person lying on the mattress is adapted without significant restrictions with regard to the structural strength of the mattress must be accepted.
  • the invention proposes that Increasing the compressive rigidity of the foam body in the longitudinal side area compared to the stiffness of the foam body in the Hip-back support area and / or to reduce the pressure rigidity of the foam body in at least a partial area of the shoulder support area compared to the pressure rigidity in the hip-back support area the coherent foam body at the corresponding Position contains a preformed foam filler, which in the contiguous foam body by inserting it correctly into a cuboid foam shape and subsequent foaming of the remaining volume of the foam mold is installed.
  • a preformed foam filler at the appropriate position is contained in the (coherent) foam body and this Foam filler in the (coherent) foam body correct insertion of the foam filler into a cuboid Foaming mold and subsequent foaming of the remaining volume of the Foam mold is installed, the foam of the Filler and the adjacent foam of the foam body during mattress manufacturing. Accordingly, it needs Foam mold used for mattress production no barriers or Have pins for separating the foam materials from one another, the unstable transition zones, especially perforation zones, in the foam body could create. Therefore, despite the use of different foam materials for the foam body on the one hand and for the filler, on the other hand, a high structural strength for the finished mattress reached.
  • stiffeners on both long sides also ensures that the user inevitably has a Lying position between the two stiffeners, i.e. in the Area of the vertical median longitudinal plane. Farther is due to the in the area of the two long sides provided stiffeners of the bed while sleeping in the Stabilized area of the vertical longitudinal median plane, see above that the risk of falling out of bed at too strong lateral displacement of the body to one Longitudinal side area is minimized.
  • the arrangement of stiffeners in the area of the two Longitudinal side surfaces also has the advantage of being independent from the spatial allocation of the mattress respectively of the bed frame equipped with the mattress the longitudinal side surface exposed at the start a seating area is available.
  • Another advantage of stabilizing the mattress i.e. the increased stiffness near the vertical long side surfaces and in the area of the hip backrest can also can be seen in the fact that near the lying one Seating provided for a visitor or reader is.

  • Foam body now by inserting a pre-formed foam filler achieved in the manner mentioned.
  • the resulting one Compressive rigidity in the shoulder rest area or in its partial area results from the pressure stiffness of the mattress base and the filler and the relative wall thicknesses of the same.
  • the sub-area reduced pressure rigidity does not extend across the entire width of the Foam body between the opposing longitudinal side surfaces, but only over a partial area between these long side surfaces, preferably over a portion that is symmetrical with respect to the vertical longitudinal median plane. Then you have in this area created a possibility of easier sinking of the shoulder, but only in this area and not in this area adjacent neighboring areas close to the long side surfaces. With that occurs a centering effect.
  • the respective preformed is installed Foam filler in such a way that the filler in advance in the foam is inserted for the mattress body, so that it is in the subsequent Foaming the foamable material filled into the mold completely or is partially foamed.
  • the mattress can be designed in such a way that on both sides of the vertical central longitudinal plane of the central hip and backrest area a seating area adjoins the two long sides here, the Compression stiffness of the foam body within the central hip-backrest area is essentially constant and also in the seating areas is essentially constant, however, larger than in the central region of the hip and back support.
