Description

La présente invention est relative à un matelas.The present invention relates to a mattress.

Le but de la présente invention consiste à présenter un matelas d'un type tout particulier, qui permet de soutenir toutes les parties du corps étendu sur ce matelas d'une manière telle à éviter toute déformation et tension nuisibles dans le corps, notamment dans la colonne vertébrale.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.

Un but particulier visé par la présente invention est de procurer un matelas présentant des propriétés thérapeutiques, c'est-à-dire un matelas qui permet de soutenir, d'une manière prédéterminée et médicalement justifiée, certaines parties du corps déviées pour les ramener dans un état normal.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.

A cet effet, suivant l'invention, le matelas comprend des moyens permettant de régler la souplesse et l'élasticité locale du matelas en fonction de la répartition du poids du corps humain couché sur ce dernier.To this end, according to the invention, 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.

Avantageusement, les moyens susdits comprennent des zones en matière sensiblement élastique juxtaposées de souplesses et duretés différentes.Advantageously, the aforementioned means comprise zones of substantially elastic material juxtaposed with different softnesses and hardnesses.

D'autres détails et particularités de l'invention ressortiront de la description donnée ci-après, à titre d'exemples non limitatifs, de quelques formes de réalisation particulières du matelas suivant l'invention avec référence aux dessins annexés.Other details and particularities of the invention will emerge from the description given below, by way of nonlimiting examples, of some particular embodiments of the mattress according to the invention with reference to the accompanying drawings.

  • La figure 1 représente un graphique montrant la variation de l'enfoncement des différentes parties d'un corps couché sur un matelas d'élasticité uniforme en fonction de la longueur du corps.FIG. 1 represents a graph showing the variation of the sinking of the different parts of a body lying on a mattress of uniform elasticity depending on the length of the body.
  • La figure 2 est une vue en perspective d'un matelas suivant une première forme de réalisation de l'objet de l'invention.Figure 2 is a perspective view of a mattress according to a first embodiment of the object of the invention.
  • La figure 3 est une coupe suivant la ligne III-III de la figure 2.Figure 3 is a section along line III-III of Figure 2.
  • La figure 4 est une vue en coupe suivant la ligne IV-IV de la figure 2.Figure 4 is a sectional view along line IV-IV of Figure 2.
  • La figure 5 est une vue en élévation, avec brisures partielles, d'une deuxième forme de réalisation de l'objet de l'invention.Figure 5 is an elevational view, partially broken, of a second embodiment of the subject of the invention.
  • La figure 6 est une coupe verticale et longitudinale d'une troisième forme de réalisation de l'objet de l'invention.Figure 6 is a vertical and longitudinal section of a third embodiment of the object of the invention.
  • Les figures 7 à 10 sont des vues en plan de quatre variantes encore de l'objet de l'invention.Figures 7 to 10 are plan views of four further variants of the subject of the invention.
  • La figure 11 est une vue en perspective d'une autre variante, particulièrement avantageuse, de l'objet de l'invention.Figure 11 is a perspective view of another variant, particularly advantageous, of the object of the invention.

Dans les différentes figures les mêmes chiffres de référence désignent des éléments identiques ou analogues.In the various figures, the same reference numerals designate identical or analogous elements.

La figure 1 montre clairement les variantes des compressions locales créées par un corps étendu sur un matelas pour lequel l'élasticité est la même à tous les endroits.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.

La zone a du graphique de la figure 1 montre l'enfoncement provoqué par la tête, la zone b l'enfoncement provoqué par les épaules, la zone c l'enfoncement provoqué par le bassin et enfin la zone d l'enfoncement provoqué par les jambes.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.

Il a été constaté que ces différences importantes d'enfoncement peuvent créer, surtout dans la colonne vertébrale, certaines distorsions qui pourraient provoquer, à la longue, une lésion permanente. Grâce au matelas suivant l'invention, qui est réalisé essentiellement en une matière sensiblement élastique, telle que de la mousse de polyuréthane, de polyéthylène ou autre, et recouverte de préférence d'une housse 7, on parvient à éviter ce risque en prévoyant des moyens pour régler la souplesse et l'élasticité locales du matelas en fonction de la répartition du poids du corps humain couché sur ce dernier, ce réglage est tel que surtout des tensions ou déformations locales, qui risquent de détériorer la colonne vertébrale d'un corps couché sur le matelas, soient évitées, tout en veillant à ce que les parties les plus lourdes du corps soient soutenues d'une manière encore suffisamment élastique et souple, contrairement à ce qui est le cas par exemple lorsqu'on utilise un matelas classique d'épaisseur relativement réduite reposant sur un support rigide.It has been found that these significant differences in penetration can create, especially in the spine, certain distortions which could cause, in the long run, a permanent lesion. Thanks to 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.

De plus, pour des personnes présentant déjà des lésions ou déformations, provenant essentiellement de la colonne vertébrale, le matelas peut être réalisé d'une manière telle que les parties atteintes du corps et la zone s'étendant autour de celles-ci soient soutenues d'une manière déterminée, médicalement justifiée et contrôlée, de façon à ramener ces parties du corps dans une position normale et ceci sans provoquer de plaies de lit.In addition, for people already with lesions or deformations, mainly from the spine, 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.

Les figures 2 à 11 montrent différentes formes de réalisation du matelas suivant l'invention qui permettent d'atteindre ce but.Figures 2 to 11 show different embodiments of the mattress according to the invention which achieve this goal.

Les figures 2 à 4 représentent un matelas pour deux personnes réalisé par exemple en mousse de polyuréthane. Ce matelas présente une série de fentes 1 délimitant des portions de mousse de forme parallélépipédique 2 dont les faces inférieures sont solidaires d'une couche de base continue 3.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.

Des élément sensiblement rigides, tels que par exemple des planchettes 4 de dimensions différentes, sont incorporés dans ces portions de mousse 2 à une distance de la surface supérieure du matelas comprise entre 0,5 et 10 cm et de préférence entre 2 et 3 cm de cette surface, de manière à créer ainsi des portions de mousse de souples- seset d'élasticités différentes. La répartion relative de ces éléments a lieu en fonction de la répartition du poids du corps humain couché sur le matelas.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.

Ces portions parallélépipédiques 4 s'étendent transversalement par rapport au sens longitudinal du matelas l'un à côté de l'autre, l'ensemble de ces portions étant entouré par un rebord latétal 5 faisant également corps avec la couche de base 3 et s'étendant au même niveau que la face supérieure de cette portion, de manière à ce que les faces supérieures du matelas soient entièrement planes.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.

Grâce à la présence des fentes 1, l'élasticité et la souplesse d'une portion déterminée 2 n'ont pratiquement aucune influence sur l'élasticité et la souplesse des portions voisines. Ceci permet donc un contrôle local assez rigoureux de la souplesse et de l'élasticité du matelas suivant l'invention.Thanks to the presence of the slots 1, the elasticity and flexibility of a given portion 2 have practically no influence on the elasticity and flexibility of the neighboring portions. This therefore allows fairly rigorous local control of the flexibility and elasticity of the mattress according to the invention.

Les figures 7 à 10 concernant des matelas présentant des portions 2 de forme et de dimensions différentes séparées par des fentes 1.FIGS. 7 to 10 relating to mattresses having portions 2 of different shape and dimensions separated by slots 1.

Dans la forme de réalisation la plus simple, .qui n'a cependant pas été montrée aux figures, on peut prévoir des éléments sensiblement rigides incorporés dans la matière élastique du matelas sans prévoir des fentes entre deux éléments consécutifs.In the simplest embodiment, which, however, has not been shown in the figures, it is possible to provide substantially rigid elements incorporated in the elastic material of the mattress without providing slots between two consecutive elements.

La figure 5 présente une autre forme de réalisation encore dans laquelle la couche de base 3 est complétée par un support rigide 6, laissant passer la transpiration, et qui, pour cette raison, peut par exemple présenter des perforations 8.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.

Au cas où ce support est suffisamment solide, il peut en fait remplacer le sommier classique.If this support is sufficiently solid, it can in fact replace the conventional box spring.

La figure 6 concerne une forme de réalisation d'un matelas dans lequel les portions 2 sont indépendantes les unes des autres et sont logées dans une enveloppe qui pourrait éventuellement constituer la housse 7 même du matelas. Cette housse est de préférence compartimentée par des cloisons transversales 9, de manière à maintenir les portions de mousse en place dans leur position relative.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.

Etant donné que dans un tel matelas une couche de base continue n'a pas été prévue, son épaisseur est relativement réduite, de sorte qu'il pourrait éventuellement être enroulé.Since in such a mattress a continuous base layer has not been provided, its thickness is relatively reduced, so that it could possibly be rolled up.

Le matelas suivant cette forme de réalisation peut avantageusement se poser sur un matelas classique ou encore sur un fauteuil, un lit de camp, etc.The mattress according to this embodiment can advantageously be placed on a conventional mattress or on an armchair, a camp bed, etc.

Comme il résulte de ce qui précède, le matelas suivant la présente invention se distingue sensiblement par rapport à la combinaison d'un sommier réalisé en des planchettes flexibles et d'un matelas classique posé sur ce sommier. En effet, même si l'on pouvait.prévoir des planchettes de flexibilité différente, par la présence du matelas posé sur le sommier, l'effet résultant de cette différence de flexibilité n'aurait plus d'effet à la face supérieure du matelas sur lequel s'étend le corps humain.As follows from the above, 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.

Dans le matelas suivant l'invention, grâce au fait que les éléments 4 se situent à proximité de la surface supérieure du matelas et sont de préférence isolés les uns des autres par les fentes 1, ces éléments ont un effet direct sur le corps même et à l'endroit désiré de' ce dernier. Ainsi, on peut contrôler parfaitement la répartition de la pression exercée par le matelas sur les différentes parties du corps.In the mattress according to the invention, thanks to the fact that 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. Thus, one can perfectly control the distribution of the pressure exerted by the mattress on the different parts of the body.

La figure 11 présente une forme de réalisation particulièrement avantageuse d'un matelas suivant l'invention.Figure 11 shows a particularly advantageous embodiment of a mattress according to the invention.

Ce matelas se caractérise surtout par le fait que les éléments 4 prévus dans les formes de réalisation précédentes ont été remplacés par des zones en matière sensiblement élastique juxtaposées de souplesses et duretés différentes.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.

Plus particulièrement, ces zones sont formées de portions de mousse de polyuréthane de densités et duretés différentes, c'est-à-dire qui varient d'un endroit à l'autre du matelas, suivant la pression locale qui y sera exercée par le corps et également suivant la nature et l'état de la partie du corps à soutenir.More particularly, 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.

Dans une forme de réalisation préférentielle de l'invention, ces zones sont déterminées par des blocs de mousse juxtaposés dans le sens de la longueur du matelas et collés intimement les uns aux autres. Dans le matelas spécifique de la figure 11, les zones sont au nombre de cinq et portent les références A, B, C, D et E. Ces zones sont formées par des blocs de mousse de polyuréthane collés les uns aux autres suivant des surfaces de contact 10 inclinées par rapport à la surface supérieure du matelas sur laquelle repose le corps.In a preferred embodiment of the invention, these zones are determined by blocks of foam juxtaposed in the direction of the length of the mattress and glued intimately to each other. In the specific mattress of FIG. 11, 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.

Ainsi, le bloc B présente une section transversale suivant le sens de la longueur du matelas de forme triangulaire, alors que les autres blocs présentent une -forme trapézoïdale.Thus, 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.

Grâce à ces surfaces inclinées 10, la transition entre l'effet de deux blocs successifs de densités et duretés différentes se fait graduellement, de sorte qu'on peut admettre que les différentes zones se confondent aux lignes de contact 11 dans la surface supérieure du matelas.Thanks to these inclined surfaces 10, the transition between the effect of two successive blocks of different densities and hardnesses takes place gradually, so that it can be assumed that the different zones merge with the contact lines 11 in the upper surface of the mattress .

Ci-après sont données, à titre d'exemple seulement, les caractéristiques des blocs A, B, C D et E.

Figure imgb0001
Below are given, by way of example only, the characteristics of blocks A, B, CD and E.
Figure imgb0001

Les dimensions extérieures de ce matelas sont :

  • hauteur : 15 cm.
  • largeur : 90 cm.
  • longueur: 195 cm.
The external dimensions of this mattress are:
  • height: 15 cm.
  • width: 90 cm.
  • length: 195 cm.

Etant donné que chaque zone du matelas suivant l'invention remplit une fonction déterminée, il doit généralement toujours être utilisé dans le même sens et avec le même cOté vers le haut.Since 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.

Dans la figure 11, la zone A est destinée à soutenir la tête, la zone B les épaules, la zone C le thorax, la zone D le bassin et la zone E les jambes.In figure 11, 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.

Il va bien entendu de soi que la présente invention n'est pas limitée aux formes de réalisation décrites et que bien des variantes peuvent être envisagées sans sortir du cadre du présent brevet.It goes without saying of course that the present invention is not limited to the embodiments described and that many variants can be envisaged without departing from the scope of this patent.

C'est ainsi par exemple que l'on pourrait combiner les éléments 4 avec des blocs de mousse de duretés et densités différentes.Thus, for example, the elements 4 could be combined with foam blocks of different hardness and density.
