Definitions

  • the present invention relates to a mattress.
  • the object of the present invention is to present a mattress of a very particular type, which makes it possible to support all the parts of the body extended on this mattress in such a way as to avoid any harmful deformation and tension in the body, in particular in the spine.
  • a particular aim of the present invention is to provide a mattress with therapeutic properties, that is to say a mattress which makes it possible to support, in a predetermined and medically justified manner, certain parts of the body deviated in order to bring them back into a normal state.
  • the mattress comprises means making it possible to adjust the flexibility and the local elasticity of the mattress as a function of the distribution of the weight of the human body lying on the latter.
  • the aforementioned means comprise zones of substantially elastic material juxtaposed with different softnesses and hardnesses.
  • Figure 1 clearly shows the variants of local compressions created by a body stretched out on a mattress for which the elasticity is the same in all places.
  • Zone a of the graph in FIG. 1 shows the depression caused by the head, zone b the depression caused by the shoulders, zone c the depression caused by the pelvis and finally the zone d the depression caused by the legs.
  • the mattress according to the invention which is made essentially of a substantially elastic material, such as polyurethane, polyethylene or other foam, and preferably covered with a cover 7, it is possible to avoid this risk by providing means for adjusting the local flexibility and elasticity of the mattress as a function of the distribution of the weight of the human body lying on the latter, this adjustment is such that above all local tensions or deformations, which risk damaging the spine of a body lying on the mattress, are avoided, while ensuring that the heaviest parts of the body are supported in a still sufficiently elastic and flexible manner, unlike what is the case for example when using a conventional mattress d 'relatively reduced thickness resting on a rigid support.
  • a substantially elastic material such as polyurethane, polyethylene or other foam
  • the mattress can be made in such a way that the affected parts of the body and the area extending around them are supported d '' in a determined, medically justified and controlled manner, so as to bring these parts of the body back to a normal position without causing bed sores.
  • FIGS 2 to 11 show different embodiments of the mattress according to the invention which achieve this goal.
  • Figures 2 to 4 show a mattress for two people made for example of polyurethane foam.
  • This mattress has a series of slots 1 delimiting portions of foam of parallelepiped shape 2, the lower faces of which are integral with a continuous base layer 3.
  • Substantially rigid elements such as for example small boards 4 of different dimensions, are incorporated into these foam portions 2 at a distance from the upper surface of the mattress of between 0.5 and 10 cm and preferably between 2 and 3 cm from this surface, so as to thus create portions of flexible foam and elasticities.
  • the relative distribution of these elements takes place according to the distribution of the weight of the human body lying on the mattress.
  • These parallelepipedic portions 4 extend transversely with respect to the longitudinal direction of the mattress one next to the other, all of these portions being surrounded by a lateral flange 5 also forming a body with the base layer 3 and s' extending at the same level as the upper face of this portion, so that the upper faces of the mattress are entirely flat.
  • FIGS. 7 to 10 relating to mattresses having portions 2 of different shape and dimensions separated by slots 1.
  • FIG. 5 shows yet another embodiment in which the base layer 3 is completed by a rigid support 6, allowing perspiration to pass through, and which, for this reason, can for example have perforations 8.
  • Figure 6 relates to an embodiment of a mattress in which the portions 2 are independent of each other and are housed in an envelope which could possibly constitute the cover 7 even of the mattress.
  • This cover is preferably compartmentalized by transverse partitions 9, so as to keep the foam portions in place in their relative position.
  • the mattress according to this embodiment can advantageously be placed on a conventional mattress or on an armchair, a camp bed, etc.
  • the mattress according to the present invention differs significantly compared to the combination of a box spring made of flexible boards and a conventional mattress placed on this box spring. Even if one could plan for boards of different flexibility, by the presence of the mattress placed on the box spring, the effect resulting from this difference in flexibility would no longer have an effect on the upper face of the mattress on which extends the human body.
  • the elements 4 are located near the upper surface of the mattress and are preferably isolated from one another by the slots 1, these elements have a direct effect on the body itself and at the desired location of the latter.
  • the elements 4 are located near the upper surface of the mattress and are preferably isolated from one another by the slots 1, these elements have a direct effect on the body itself and at the desired location of the latter.
  • Figure 11 shows a particularly advantageous embodiment of a mattress according to the invention.
  • This mattress is characterized above all by the fact that the elements 4 provided in the previous embodiments have been replaced by zones of substantially elastic material juxtaposed with different softnesses and hardnesses.
  • these zones are formed by portions of polyurethane foam of different densities and hardnesses, that is to say which vary from one place to another of the mattress, according to the local pressure which will be exerted there by the body. and also depending on the nature and condition of the part of the body to be supported.
  • these zones are determined by blocks of foam juxtaposed in the direction of the length of the mattress and glued intimately to each other.
  • the zones are five in number and bear the references A, B, C, D and E.
  • These zones are formed by blocks of polyurethane foam glued to one another along surfaces of contact 10 inclined with respect to the upper surface of the mattress on which the body rests.
  • the block B has a cross section along the direction of the length of the triangular mattress, while the other blocks have a trapezoidal shape.
  • each zone of the mattress according to the invention fulfills a specific function, it must generally always be used in the same direction and with the same side up.
  • zone A is intended to support the head, zone B the shoulders, zone C the thorax, zone D the pelvis and zone E the legs.
  • the elements 4 could be combined with foam blocks of different hardness and density.
  • bearing capacity can also be obtained using materials of equal hardness, but having another shape or structure (such as distribution and dimensions of cells or profiling, etc.)
