Definitions

  • the invention relates to a cushion body for mattresses or the like according to the preamble of claim 1.
  • a mattress made of soft elastic foam which consists of two loosely stacked foam parts of different compression hardness.
  • the mutually facing surfaces have a sinusoidal wave profile that extends over the entire width.
  • the frequency and the amplitude of the wave profiles of both parts are constant.
  • the amplitude of the wave profile of the two foam parts are the same in such a way that one is designed as a positive part and the other as a negative part, so that the two parts form one unit when they mesh with one another.
  • the hardness characteristic of this mattress is constant over its length.
  • a foam mattress which consists of two flat foam sheets.
  • the upper foam sheet is divided into several sections, at least one of which consists of a material of higher hardness. The The characteristic changes step-wise during the transition from one section to the other, which is undesirable from an orthopedic point of view.
  • the object of the invention is to provide a cushion body, the compression hardness of which can be individually adapted to the orthopedic requirements.
  • the compression hardness enables the desired effect of the continuous increase in hardness towards the center by changing the frequency and the amplitude of the wave profile in a simple manner.
  • the frequency and / or the amplitude over e.g. the length of a mattress can be designed as any hard or soft zone according to the orthopedic requirements.
  • the first foam part 2 and 3 consist of a material of different hardness.
  • the lower part 2 of the mattress 1 is preferably made of a foam of higher compression hardness.
  • the mutually facing surfaces have a sinusoidal wave profile 4, with which, as shown, they lie over one another loosely over the entire surface.
  • the wave profile 4 of the upper mattress part 3 is designed to be negative compared to the wave profile 4 of the lower mattress part 2. This requirement is due to a continuously changing wave profile 4 in frequency f and amplitude a. Based on the proportions of a person, the support in the lumbar region of a mattress must be greater than in the shoulder and leg area; only then can an orthopedically perfect rest position be achieved.
  • both the frequency f of the wave profile 4 and its amplitude a increase steadily from the two ends towards the center M.
  • the lower mattress part 2 made of harder foam material comes into play more and more.
  • any desired degree of hardness can be achieved over the length of a mattress by changing the frequency and / or amplitude profile.
  • the two foam parts 2 and 3 of different compression hardness required for a mattress 1 are produced in a very economical manner.
  • By means of a computer-controlled cutting cut the two plates in the middle according to the required wave profile 4. This results in a positive and a negative foam part 2 and 3, respectively.
  • a positive and a negative part together result in a mattress 1.
  • the loose foam parts 2 and 3 are covered by an air-permeable and elastic covering, not shown, e.g. a tubular jersey fabric held together. The whole is still surrounded by a fabric cover, not shown.
  • FIG. 2 shows the suspension diagram of the mattress 1 and FIG. 3 shows the resulting compression hardness curve.
  • the characteristic curve I in FIG. 2 shows the spring characteristic of the mattress 1 at the two ends A / E as a function of the contact pressure P, while the characteristic curve II shows the spring characteristic in the middle M of the mattress 1.
  • the constantly changing frequency f and amplitude a of the wave profile 4 from the ends A / E to the center M of the mattress 1 result in a length l of the mattress 1 of e.g. a compression hardness curve of between two and three to five kilopascals.

Claims (4)

  1. Corps rembourré (1) en mousse souple pour matelas ou autres choses du même genre, composé de deux pièces en mousse (2, 3), elles aussi, superposées et dotées d'une résistance à l'écrasement différente, et sur lequel les surfaces tournées l'une vers l'autre présentent un profil ondulé (4) sinusoïdal, étant entendu que la fréquence et que l'amplitude du profil ondulé des deux pièces en mousse sont identiques en ceci que l'une a la configuration d'une pièce positive et que l'autre celle d'une pièce négative si bien que les deux pièces en s'imbriquant l'une dans l'autre forment une unité,
    caractérisé par le fait que la fréquence (f) et que l'amplitude (a) des profils ondulés (4) des pièces en mousse (2,3) se modifient en permanence d'une extrémité à l'autre du corps rembourré (1).
  2. Corps rembourré conforme à la revendication 1, caractérisé par le fait que la fréquence (f) et que l'amplitude (a) sont à leur maximum au centre (M) du corps rembourré (1) pour tendre à zéro en son extrémité.
  3. Corps rembourré conforme à la revendication 1, caractérisé par le fait que les deux pièces en mousse (2,3) sont posées lâchement l'une sur l'autre et qu'elles sont retenues par un revêtement élastique.
  4. Corps rembourré conforme à la revendication 3, caractérisé par le fait que le revêtement est un tricot tubulaire.
