Description

L'invention se rapporte au domaine des nécessités de vie et notamment au matériel de couchage et aux éléments de literie. L'invention concerne plus particulièrement bien que non exclusivement un matelas subdivisé en portions dans le sens de sa grande longueur pour définir des zones de repos diversifiées et adaptées à la morphologie et aux besoins d'un utilisateur.The invention relates to the field of the necessities of life and in particular to sleeping equipment and bedding elements. The invention more particularly relates that not exclusively a mattress divided into portions in the direction of its great length to define rest areas diversified and adapted to the morphology and needs of a user.

L'invention a plus spécifiquement pour objet un matelas destiné aux enfants comme aux adultes assurant un maintien de l'utilisateur lors de l'utilisation du matelas, ledit maintien pouvant être adapté selon la morphologie et/ou le souhait du dormeur.The invention more specifically relates to a mattress for children and adults ensuring maintenance of the user when using the mattress, said maintenance can be adapted to the morphology and / or the wish of the sleeper.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Les éléments de literie que sont les matelas traditionnels sont réalisés selon deux techniques bien différentes. Il existe ainsi les matelas comportant une carcasse interne métallique plus généralement appelés « matelas à ressort » et les matelas comportant un ou plusieurs blocs de mousse dits « matelas élastiques ».The bedding elements that are traditional mattresses are made according to two very different techniques. There are thus mattresses with an internal metal carcass more generally called "spring mattress" and mattresses comprising one or more foam blocks called "elastic mattresses".

Toutefois, du fait des dimensions de tels matelas traditionnels, lesdits matelas sont souvent lourds et difficile à transporter. En outre, le stockage de tels matelas s'avère extrêmement coûteux car pour répondre aux besoins d'une clientèle, un vendeur doit pouvoir avoir à sa disposition un ensemble de modèles de matelas de taille et de caractéristiques différentes.However, because of the dimensions of such traditional mattresses, said mattresses are often heavy and difficult to transport. In addition, the storage of such mattresses is extremely expensive because to meet the needs of a customer, a seller must be able to have at his disposal a set of mattress models size and different characteristics.

Il a ainsi été proposé dans le document FR 2 563 420 un matelas constitué d'éléments à ressorts élémentaires articulés entre eux au moyen de fermetures à glissière ou de crochets.It has been proposed in the document FR 2 563 420 a mattress consisting of elements with elementary springs hinged together by means of zippers or hooks.

Or les fermetures à glissières ou les crochets peuvent compromettre la planéité du matelas. En plus, la présence de portions en relief des fermetures à glissières ou des crochets peut s'avère inconfortable ou désagréable pour un utilisateur.But zippers or hooks can compromise the flatness of the mattress. In addition, the presence of raised portions of the zippers or hooks can be uncomfortable or uncomfortable for a user.

Le document FR 2 730 914 divulgue un matelas formé d'une pluralité de blocs réalisés en mousse élastomère présentant chacun des chants latéraux et des surfaces principales horizontales. Les chants latéraux des différents blocs présentent des formes découpées complémentaires permettant l'encastrement des blocs les uns dans les autres.The document FR 2,730,914 discloses a mattress formed of a plurality of blocks made of elastomeric foam each having side edges and horizontal main surfaces. The side edges of the different blocks have complementary cut-out shapes allowing the blocks to be inserted into one another.

De la même façon, les différents blocs assemblés s'avèrent ne pas former un matelas plan de sorte qu'un utilisateur peut se retrouver gêné par l'irrégularité de la surface de l'ensemble.In the same way, the various assembled blocks are found not to form a flat mattress so that a user may find themselves bothered by the irregularity of the surface of the assembly.

En outre, il s'avère nécessaire de réaliser un assemblage d'un grand nombre de blocs pour permettre d'obtenir un matelas de taille respectable sur lequel peut s'allonger un utilisateur.In addition, it is necessary to achieve an assembly of a large number of blocks to obtain a respectable sized mat on which can stretch a user.

Le document EP 1 329 177 présente ainsi un matelas comportant une structure non déformable qui comprend un ou deux réceptacles. Les deux réceptacles sont alors destinés à recevoir chacun un sous-matelas en matériau synthétique, les sous-matelas pouvant ainsi être adaptés aux besoins d'un utilisateur.The document EP 1 329 177 thus presents a mattress comprising a non-deformable structure which comprises one or two receptacles. The two receptacles are then intended to each receive a sub-mattress synthetic material, the sub-mattress can be adapted to the needs of a user.

Toutefois, la structure recevant les sous-matelas s'avère elle-même relativement encombrante et lourde.However, the structure receiving the sub-mattress itself is relatively bulky and heavy.

Par ailleurs, le document DE202009008359 U1 décrit un élément de literie selon le préambule de la revendication 1.In addition, the document DE202009008359 U1 describes a bedding element according to the preamble of claim 1.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de l'invention est de proposer un élément de literie obviant au moins en partie aux problèmes précités.An object of the invention is to provide a bedding element at least partially obviating the aforementioned problems.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

En vue de la réalisation de ce but, on propose un élément de literie tel que revendiqué dans la revendication 1.In order to achieve this goal, there is provided a bedding element as claimed in claim 1.

Par zone de repos on entend ici la face principale sur laquelle l'utilisateur s'allonge, compte tenu du sens d'utilisation de l'élément de literie. Il y donc deux zones de repos par face principale, soit au total quatre zones de repos.By rest zone is meant here the main face on which the user lies, taking into account the direction of use of the bedding element. There are two rest zones per main face, ie a total of four rest zones.

Par profil d'accueil, on entend ici la suite des caractéristiques mécaniques des zones d'accueil successives qui constituent chaque zone de repos. On peut également parler de densité d'accueil de la zone de repos.By reception profile, here means the following mechanical characteristics of the successive reception areas that constitute each rest area. We can also speak of density of reception of the rest area.

Ainsi, un même élément de literie selon l'invention permet d'offrir quatre zones de repos avec des profils d'accueil distincts. On peut donc utiliser cet élément de literie de quatre façons différentes. On peut ainsi dire qu'un tel élément de literie est réservable sur « quatre côtés ».Thus, the same bedding element according to the invention allows to offer four rest areas with separate home profiles. We can use this bedding element in four different ways. It can be said that such a bedding element is bookable on "four sides".

Chaque utilisateur peut ainsi choisir la zone de repos la plus adaptée à sa morphologie ou à ses besoins. En conséquence, un même élément de literie selon l'invention assure un repos et une relaxation complète à un grand nombre d'utilisateurs. Les profils d'accueil distincts permettent d'assurer à un utilisateur qu'au moins l'une des zones de repos pourra être adaptée à sa morphologie ce qui lui garantira une sensation de relaxation qui est la base d'un sommeil reposant.Each user can choose the rest zone that best suits their morphology or their needs. As a result, the same bedding element according to the invention provides rest and relaxation for a large number of users. The distinct home profiles ensure that a user at least one of the rest areas can be adapted to its morphology which will ensure a feeling of relaxation that is the basis of a restful sleep.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 et 2, selon un premier mode de réalisation de l'invention, le matelas comporte une première grande face principale 1 opposée à une deuxième grande face principale 2. Le matelas est ici subdivisé en sept portions (les divisions sont représentées en pointillés) dans le sens de sa grande longueur qui définissent :

  • au niveau de la première grande face principale 1, des zones d'accueil successives A1, A2, A3, A4, A5, A6, A7 dont une succession A1 à A7 définit une première zone de repos et dont une succession inverse A7 à A1 définit une deuxième zone de repos ;
  • au niveau de la deuxième grande face principale, des zones d'accueil successives B1, B2, B3, B4, B5, B6, B7 (comme plus visible à la figure 2) dont une succession B1...B7 définit une troisième zone de repos et dont une succession inverse B7...B1 définit une quatrième zone de repos.
With reference to Figures 1 and 2 according to a first embodiment of the invention, the mattress comprises a first large main face 1 opposite a second large main face 2. The mattress is here subdivided into seven portions (the divisions are shown in dotted lines) in the direction of its great length which define:
  • at the level of the first large main face 1, successive reception areas A1, A2, A3, A4, A5, A6, A7 whose succession A1 to A7 defines a first rest zone and whose inverse succession A7 to A1 defines a second rest area;
  • at the level of the second large main face, successive reception areas B1, B2, B3, B4, B5, B6, B7 (as more visible at the figure 2 ) whose succession B1 ... B7 defines a third rest zone and whose inverse succession B7 ... B1 defines a fourth rest zone.

Ainsi, lorsque l'utilisateur utilise la première zone de repos, la zone d'accueil A1 reçoit la tête, la zone d'accueil A2 reçoit les épaules, la zone d'accueil A3 reçoit les vertèbres lombaires et la zone d'accueil A4 reçoit le bassin de l'utilisateur. Les zones d'accueil A5 à A7 reçoivent le reste du corps de l'utilisateur.Thus, when the user uses the first rest area, the reception area A1 receives the head, the reception area A2 receives the shoulders, the reception area A3 receives the lumbar vertebrae and the reception area A4 receives the user's pool. Welcome areas A5 to A7 receive the rest of the user's body.

Lorsque l'utilisateur utilise la deuxième zone de repos, la zone d'accueil A7 reçoit la tête, la zone d'accueil A6 reçoit les épaules, la zone d'accueil A5 reçoit les vertèbres lombaires et la zone d'accueil A4 reçoit le bassin de l'utilisateur. Les zones d'accueil A3 à A1 reçoivent le reste du corps de l'utilisateur.When the user uses the second rest zone, the reception area A7 receives the head, the reception area A6 receives the shoulders, the reception area A5 receives the lumbar vertebrae and the reception area A4 receives the user's pool. The home areas A3 to A1 receive the rest of the user's body.

Il en est de même bien sûr pour les zones de repos B1...B7 et B7...B1.It is the same of course for the rest zones B1 ... B7 and B7 ... B1.

Il est ainsi possible d'utiliser le matelas selon quatre sens d'utilisation en fonction de la zone de repos que l'utilisateur utilise, de sorte que l'on peut dire que le matelas est réversible sur quatre côtés.It is thus possible to use the mattress in four directions of use depending on the rest area that the user uses, so that we can say that the mattress is reversible on four sides.

Selon l'invention, les quatre zones de repos présentent des profils d'accueil distincts, un utilisateur pouvant aisément trouver une zone de repos adaptée à sa morphologie et à ses besoins.According to the invention, the four rest areas have distinct home profiles, a user can easily find a rest area adapted to its morphology and its needs.

Pour obtenir ces profils d'accueil distincts, le matelas comporte ici :

  • une première couche externe 3 s'étendant pour former la première grande face principale 1, la première couche externe 3 étant ici constituée d'un premier bloc 6 et d'un deuxième bloc 7 se rejoignant au niveau d'une une zone de jonction qui s'étend au milieu de la zone d'accueil A4 destinée à recevoir le bassin d'un utilisateur
  • une deuxième couche externe 4 s'étendant pour former la deuxième grande face principale 2, la deuxième couche externe 4 étant ici constituée d'un premier bloc 8 et d'un deuxième bloc 9 se rejoignant au niveau d'une zone de jonction qui s'étend au milieu de la zone d'accueil B4 destinée à recevoir le bassin d'un utilisateur.
  • et une couche intermédiaire 5 disposée entre les deux couches externes, et formée ici d'un seul bloc.
To obtain these distinct home profiles, the mattress has here:
  • a first outer layer 3 extending to form the first large main face 1, the first outer layer 3 being constituted by a first block 6 and a second block 7 joining at a junction zone which extends in the middle of the A4 reception area intended to receive a user's pelvis
  • a second outer layer 4 extending to form the second large main face 2, the second outer layer 4 being constituted by a first block 8 and a second block 9 joining at a junction zone which extends in the middle of the reception area B4 intended to receive the basin of a user.
  • and an intermediate layer 5 disposed between the two outer layers, and formed here in a single block.

Les deux blocs formant chacune des couches externes 3, 4 sont par exemple assemblés par collage ou par adhésion.The two blocks forming each of the outer layers 3, 4 are for example assembled by gluing or adhesion.

Selon le mode de réalisation illustré ici, la couche de matériau intermédiaire 5 a une épaisseur non uniforme. La couche de matériau intermédiaire 5 comporte ainsi des saillies de forme prismatique 10 (dont une seule est référencée à la figure 1) qui pénètrent dans des indentations conformes des couches externes 3,4. Les saillies 10 sont agencées de sorte que l'épaisseur de la couche de matériau intermédiaire 5 varie en passant d'une portion à l'autre du matelas.According to the embodiment illustrated here, the intermediate material layer 5 has a non-uniform thickness. The layer of intermediate material 5 thus has prismatic projections 10 (only one of which is referenced to FIG. figure 1 ) who enter conformal indentations of the outer layers 3,4. The projections 10 are arranged so that the thickness of the layer of intermediate material 5 varies from one portion to the other of the mattress.

En outre, les différents blocs constituant les couches sont de préférence réalisés dans des matériaux divers qui confèrent ainsi des caractéristiques mécaniques particulières aux différentes zones d'accueil par exemple en termes d'élasticité, de souplesse, de fermeté ...In addition, the various blocks constituting the layers are preferably made of various materials which thus confer particular mechanical characteristics to the different reception areas for example in terms of elasticity, flexibility, firmness ...

Ainsi, par exemple, les blocs 6, 7, 8, 9 sont réalisés dans des mousses élastomériques de souplesse distinctes. Ces différences de caractéristiques mécaniques, associées à la géométrie des couches du matelas, produisent les profils d'accueil représentés à la figure 2bis, en l'occurrence ici des profils de souplesse, qui sont bien distincts les uns des autres.Thus, for example, the blocks 6, 7, 8, 9 are made in elastomeric foams of distinct flexibility. These differences in mechanical characteristics, associated with the geometry of the layers of the mattress, produce the profiles of reception represented in the figure 2bis Here, in this case, profiles of flexibility, which are quite distinct from each other.

De préférence, la couche de matériau intermédiaire 5 est réalisée dans un matériau beaucoup plus ferme que les matériaux des couches externes. De cette façon, un utilisateur ressentira moins durement le soutien apporté par la couche intermédiaire 5 grâce à un amortissement apporté par les couches externes.Preferably, the layer of intermediate material 5 is made of a much firmer material than the materials of the outer layers. In this way, a user will feel less hard the support provided by the intermediate layer 5 through damping provided by the outer layers.

En référence à la figure 2, selon un mode de réalisation particulier, le matelas a les dimensions indicatives suivantes :

  • une longueur l de 200 centimètres ;
  • une largeur L de 90 centimètres ;
  • une épaisseur e de 20 centimètres.
With reference to the figure 2 according to a particular embodiment, the mattress has the following indicative dimensions:
  • a length l of 200 centimeters;
  • a width L of 90 centimeters;
  • a thickness e of 20 centimeters.

Les zones d'accueil ont les dimensions indicatives suivantes :

  • les zones d'accueil A1, A7, B1, B7 ont une longueur l1 de 20 centimètres ;
  • les zones d'accueil A2, A6, B2, B6 ont une longueur l2 de 30 centimètres ;
  • les zones d'accueil A3, A5, B3, B5 ont une longueur l3 de 30 centimètres ;
  • les zones d'accueil A4 et B4 ont une longueur l4 de 40 centimètres.
The reception areas have the following indicative dimensions:
  • the reception areas A1, A7, B1, B7 have a length l 1 of 20 centimeters;
  • the reception areas A2, A6, B2, B6 have a length l 2 of 30 centimeters;
  • the reception areas A3, A5, B3, B5 have a length l 3 of 30 centimeters;
  • A4 and B4 reception areas have a length l 4 40 centimeters.

Les couches ont les dimensions indicatives suivantes :

  • au niveau des zones d'accueil A1, A7, B1, B7, la couche intermédiaire a une épaisseur d1 de 14 centimètres et les couches externes ont une épaisseur c1 de 3 centimètres chacune ;
  • au niveau des zones d'accueil A2, A6, B2, B6, la couche intermédiaire a une épaisseur d1 de 6 centimètres et les couches externes ont une épaisseur c1 de 7 centimètres chacune ;
  • au niveau des zones d'accueil A3, A5, B3, B5, la couche intermédiaire a une épaisseur d1 de 14 centimètres et les couches externes ont une épaisseur c1 de 3 centimètres chacune ;
  • au niveau des zones d'accueil A4 et B4, la couche intermédiaire a une épaisseur d1 de 10 centimètres et les couches externes ont une épaisseur c1 de 5 centimètres chacune.
The layers have the following indicative dimensions:
  • at the reception areas A1, A7, B1, B7, the intermediate layer has a thickness d1 of 14 centimeters and the outer layers have a thickness c1 of 3 centimeters each;
  • at the reception areas A2, A6, B2, B6, the intermediate layer has a thickness d1 of 6 centimeters and the outer layers have a thickness c1 of 7 centimeters each;
  • at the reception areas A3, A5, B3, B5, the intermediate layer has a thickness d1 of 14 centimeters and the outer layers have a thickness c1 of 3 centimeters each;
  • at the reception areas A4 and B4, the intermediate layer has a thickness d1 of 10 centimeters and the outer layers have a thickness c1 of 5 centimeters each.

En référence à la figure 3, selon une variante du premier mode de réalisation de l'invention, les blocs 6,7 de la première couche externe 3 et les blocs 8,9 de la deuxième couche externe 4 sont agencés de sorte que les zones de jonction entre les blocs constituant une même couche se situent sensiblement au niveau de la frontière entre deux zones d'accueil, ici à la frontière entre les zones d'accueil A4,A5 et B3,B4, respectivement. Ainsi, la jonction n'est plus située au milieu d'une zone d'accueil ce qui évite le saut du profil d'accueil au niveau des zones d'accueil A4 et B4, visible à la figure 2bis, et améliore le confort d'un utilisateur qui ne ressent alors pas ou peu la zone de jonction.With reference to the figure 3 according to a variant of the first embodiment of the invention, the blocks 6, 7 of the first outer layer 3 and the blocks 8, 9 of the second outer layer 4 are arranged in such a way that the junction zones between the constituent blocks The same layer is located substantially at the border between two reception areas, here at the border between reception areas A4, A5 and B3, B4, respectively. Thus, the junction is no longer located in the middle of a reception area which avoids the jump of the reception profile at the reception areas A4 and B4, visible at the figure 2bis , and improves the comfort of a user who then feels little or no junction area.

En référence à la figure 3bis, une autre variante du premier mode de réalisation de l'invention va être à présent décrite.With reference to the figure 3bis another variant of the first embodiment of the invention will now be described.

Le matelas comporte ici :

  • une première couche externe 13 s'étendant pour former la première grande face principale 11, la première couche externe 13 étant ici constituée d'un premier bloc 16 et d'un deuxième bloc 17 se rejoignant au niveau d'une une zone de jonction qui s'étend ici au niveau de la frontière entre les zones d'accueil A4 et A5
  • une deuxième couche externe 14 s'étendant pour former la deuxième grande face principale 12, la deuxième couche externe 14 étant ici constituée d'un premier bloc 18 et d'un deuxième bloc 19 se rejoignant au niveau d'une zone de jonction qui s'étend ici au niveau de la frontière entre les zones d'accueil B5 et B4
  • et une couche intermédiaire 15 disposée entre les deux couches externes.
The mattress has here:
  • a first outer layer 13 extending to form the first large main face 11, the first outer layer 13 being constituted by a first block 16 and a second block 17 joining at a junction zone which extends here at the border between the A4 and A5 reception areas
  • a second outer layer 14 extending to form the second large main face 12, the second outer layer 14 being constituted by a first block 18 and a second block 19 joining at a junction zone which s extends here at the border between reception areas B5 and B4
  • and an intermediate layer 15 disposed between the two outer layers.

Selon la variante illustrée ici, la couche de matériau intermédiaire 15 a une épaisseur uniforme et est ici constituée de sept blocs, deux blocs consécutifs se rejoignant au niveau d'une zone de jonction qui s'étend elle-même au niveau de la frontière entre deux zones d'accueil consécutives.According to the variant illustrated here, the layer of intermediate material 15 has a uniform thickness and here consists of seven blocks, two consecutive blocks meeting at a junction zone which extends itself at the boundary between two consecutive reception areas.

Les sept blocs de la couche intermédiaire 15 sont réalisés dans des matériaux divers qui confèrent ainsi des caractéristiques mécaniques particulières aux différentes zones d'accueil par exemple en termes d'élasticité, de souplesse, de fermeté ... De préférence, la couche de matériau intermédiaire 15 est constituée d'une poche comportant les sept blocs, chaque bloc étant formé par des ressorts de raideur différent de sorte que chaque bloc ait une raideur différente.The seven blocks of the intermediate layer 15 are made of various materials which thus confer particular mechanical characteristics to the different reception areas, for example in terms of elasticity, flexibility, firmness ... Preferably, the layer of material intermediate 15 consists of a pocket with the seven blocks, each block being formed by springs of different stiffness so that each block has a different stiffness.

Ces différences de caractéristiques mécaniques produisent des profils d'accueil qui sont bien distincts les uns des autres.These differences in mechanical characteristics produce host profiles that are distinct from each other.

En référence à la figure 4, un deuxième mode de réalisation va être à présent décrit, les éléments communs avec le premier mode de réalisation ayant les mêmes références augmentées d'une centaine.With reference to the figure 4 a second embodiment will now be described, the elements common with the first embodiment having the same references increased by one hundred.

Dans ce second mode de réalisation, la première couche externe 103 est d'un seul bloc. La deuxième couche externe 104 est également d'un seul bloc.In this second embodiment, the first outer layer 103 is a single block. The second outer layer 104 is also self-contained.

La couche de matériau intermédiaire 105 est en revanche constituée d'un premier bloc 111 et un deuxième bloc 112, les deux blocs étant de forme symétrique.On the other hand, the layer of intermediate material 105 consists of a first block 111 and a second block 112, the two blocks being of symmetrical shape.

Le premier bloc 111 comporte :

  • une première section s'étendant sous la zone d'accueil A1 ;
  • une deuxième section s'étendant sous la zone d'accueil A2 d'une épaisseur moindre que la première section;
  • une troisième section s'étendant sous la zone d'accueil A3 d'une même épaisseur que la première section ;
  • une quatrième section s'étendant sous la zone d'accueil A4 d'une épaisseur moitié moindre que celle de la deuxième section.
The first block 111 comprises:
  • a first section extending below the reception area A1;
  • a second section extending beneath the reception area A2 of a thickness less than the first section;
  • a third section extending beneath the reception area A3 of the same thickness as the first section;
  • a fourth section extending under the reception area A4 half the thickness of the second section.

De façon symétrique, le deuxième bloc 112 comporte :

  • une première section s'étendant sous la zone d'accueil A7 identique à la première section du premier bloc 111 ;
  • une deuxième section s'étendant sous la zone d'accueil A6 identique à la deuxième section du premier bloc 111;
  • une troisième section s'étendant sous la zone d'accueil A5 identique à la troisième section du premier bloc 111 ;
  • une quatrième section s'étendant sous les zones d'accueil A4 d'une épaisseur identique à celle de la quatrième section du premier bloc 111.
Symmetrically, the second block 112 comprises:
  • a first section extending under the reception area A7 identical to the first section of the first block 111;
  • a second section extending beneath the reception area A6 identical to the second section of the first block 111;
  • a third section extending under the reception area A5 identical to the third section of the first block 111;
  • a fourth section extending beneath the reception areas A4 of a thickness identical to that of the fourth section of the first block 111.

Les deux blocs sont conformés de sorte que lorsqu'ils sont assemblés, la quatrième section du premier bloc 111 vient chevaucher la quatrième section du deuxième bloc 112. Les deux blocs sont par exemple assemblés par collage ou par adhésion.The two blocks are shaped so that when they are assembled, the fourth section of the first block 111 overlaps the fourth section of the second block 112. The two blocks are for example assembled by gluing or adhesion.

Du fait de la variation de l'épaisseur de leurs différentes sections, les deux blocs de la couche de matériau intermédiaire 105 comportent des saillies de forme prismatiques 110 (dont une seule est référencée à la figure 4) qui coopèrent avec des indentations correspondantes des couches externes 103 et 104.Due to the variation in the thickness of their different sections, the two blocks of the layer of intermediate material 105 comprise prismatic projections 110 (only one of which is referenced to FIG. figure 4 ) which cooperate with corresponding indentations of the outer layers 103 and 104.

Selon un mode particulier de réalisation, la première couche externe 103 est ici en mousse à mémoire de forme ayant une résilience R1, la deuxième couche externe 104 est ici en mousse à mémoire de forme ayant une résilience R2, tandis que le premier bloc 111 est formé de ressorts de raideur k1 et le deuxième bloc 112 est formé de ressorts de raideur k2. On remarquera que chaque bloc 111 et 112 comprend des ressorts de hauteur différente selon la zone d'accueil dans laquelle les ressorts s'étendent.According to a particular embodiment, the first outer layer 103 is here made of shape memory foam having a resilience R1, the second outer layer 104 is here in memory foam having a resilience R2, while the first block 111 is formed of stiffness springs k1 and the second block 112 is formed of stiffness springs k2. It will be noted that each block 111 and 112 comprises springs of different height depending on the reception zone in which the springs extend.

Les deux blocs de la couche intermédiaire et les deux couches externes étant composés d'éléments ayant des propriétés mécaniques distinctes, les quatre zones de repos ont ainsi des profils d'accueil distincts.Since the two blocks of the intermediate layer and the two outer layers are composed of elements having distinct mechanical properties, the four rest zones thus have distinct home profiles.

Ici, les blocs de la couche de matériau intermédiaire 105 présentent des faces ondulées alors que les faces en regard des couches externes sont planes. Des espaces sont ainsi créés entre la couche intermédiaire 105 et les couches externes 103,104 lorsque le matelas est formé. Ces espaces se présentent sous la forme de conduits s'étendant sur toute la largeur du matelas et permettent une meilleure ventilation de celui-ci.Here, the blocks of the layer of intermediate material 105 have corrugated faces while the facing faces of the outer layers are planar. Spaces are thus created between the intermediate layer 105 and the outer layers 103, 104 when the mattress is formed. These spaces are in the form of ducts extending over the entire width of the mattress and allow a better ventilation thereof.

De préférence, les faces extérieures des couches externes 103,104 formant la première face principale et la deuxième face principale sont également ondulées. Ces ondulations permettent également une meilleure ventilation du matelas. En outre, elles permettent de masser l'utilisateur lorsque celui-ci change de position, notamment si le matelas est utilisé avec un sommier électrique.Preferably, the outer faces of the outer layers 103, 104 forming the first main face and the second main face are also corrugated. These ripples also allow better ventilation of the mattress. In addition, they allow to massage the user when it changes position, especially if the mattress is used with an electric bed.

Le matelas selon l'invention offre ainsi quatre zones de repos différentes et donc quatre conforts différents.The mattress according to the invention thus offers four different rest zones and therefore four different comforts.

En référence à la figure 5, un troisième mode de réalisation va être à présent décrit. Les éléments communs avec le premier mode de réalisation ayant les mêmes références augmentées de deux centaines.With reference to the figure 5 a third embodiment will now be described. The elements common with the first embodiment having the same references increased by two hundred.

Dans ce second mode de réalisation, la première couche externe 203 est d'un seul bloc. La deuxième couche externe 204 est également d'un seul bloc. La couche de matériau intermédiaire 205 est aussi constituée d'un seul bloc 213. La première couche externe 203 et la deuxième couche externe 204 sont en matériaux distincts.In this second embodiment, the first outer layer 203 is a single block. The second outer layer 204 is also self-contained. The layer of intermediate material 205 is also constituted of a single block 213. The first outer layer 203 and the second outer layer 204 are made of different materials.

Le bloc 213 de la couche intermédiaire 205 comporte ici sept sections s'étendant chacune sous une zone d'accueil différente. Au moins deux sections de la couche intermédiaire 205 ont des épaisseurs distinctes de sorte qu'au moins une des sections du bloc 213 s'étendant sous la zone d'accueil A1 ou A2 ou A3 ait une épaisseur distincte d'une des sections du bloc 213 s'étendant sous la zone d'accueil A5, A6 ou A7. De la sorte, le bloc 213 aura un profil asymétrique selon que l'on considère la succession A1 à A7 ou la succession A7 à A1. De la même manière, le bloc 213 aura un profil asymétrique selon que l'on considère la succession B1 à B7 ou la succession B7 à B1.The block 213 of the intermediate layer 205 here comprises seven sections each extending under a different reception area. At least two sections of the intermediate layer 205 have distinct thicknesses so that at least one of the sections of the block 213 extending below the reception area A1 or A2 or A3 has a thickness distinct from one of the sections of the block 213 extending under the reception area A5, A6 or A7. In this way, the block 213 will have an asymmetrical profile depending on whether one considers the succession A1 to A7 or the succession A7 to A1. In the same way, the block 213 will have an asymmetrical profile depending on whether one considers the succession B1 to B7 or the succession B7 to B1.

Du fait de la variation de l'épaisseur de ses différentes sections, le bloc 213 de la couche de matériau intermédiaire 205 comportent des saillies de forme prismatiques 210 (dont une seule est référencée à la figure 5) qui coopèrent avec des indentations correspondantes des couches externes 203 et 204.Because of the variation in the thickness of its different sections, the block 213 of the intermediate material layer 205 comprises shaped projections prismatic 210 (only one of which is referenced figure 5 ) which cooperate with corresponding indentations of the outer layers 203 and 204.

Les deux couches externes 203 et 204 étant composées d'éléments ayant des propriétés mécaniques distinctes, et la couche intermédiaire 205 ayant un profil asymétrique entre les zones A1 à A3 et les zones A5 à A7, les quatre zones de repos ont ainsi des profils d'accueil distincts.Since the two outer layers 203 and 204 are composed of elements having distinct mechanical properties, and the intermediate layer 205 having an asymmetrical profile between the zones A1 to A3 and the zones A5 to A7, the four rest zones thus have profiles of 'separate home.

Le matelas selon l'invention offre ainsi quatre zones de repos différentes et donc quatre conforts différents.The mattress according to the invention thus offers four different rest zones and therefore four different comforts.

Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Naturally, the invention is not limited to the embodiment described and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.

En particulier, les dimensions du matelas pourront être différentes de celles citées en variant dans de larges proportions. Par exemple, la largeur du matelas pourra varier entre 70 et 200 centimètres. De préférence, l'épaisseur du matelas variera entre 15 et 35 centimètres. De préférence, chaque zone d'accueil a une longueur de 30 centimètre environ.In particular, the dimensions of the mattress may be different from those quoted by varying in large proportions. For example, the width of the mattress may vary between 70 and 200 centimeters. Preferably, the thickness of the mattress will vary between 15 and 35 centimeters. Preferably, each reception area has a length of about 30 centimeters.

Le matelas peut également être réalisé sur mesure lorsqu'un utilisateur a une morphologie particulière en adaptant les matériaux et/ou les dimensions pour permettre une répartition de poussée différente selon les problèmes morphologiques ou pathologiques de l'utilisateur.The mattress can also be custom made when a user has a particular morphology by adapting the materials and / or dimensions to allow a different thrust distribution depending on the morphological or pathological problems of the user.

Par ailleurs, pour un matelas de grandes dimensions comme par exemple de 160 centimètres de largeur, on pourra utiliser un unique matelas ou encore disposer deux matelas identiques selon l'invention et les relier entre eux par une bande adhésive comme un matériau scratch ou une bande périphérique élastique ou encore avec une housse commune recouvrant les deux matelas, la housse étant de préférence élastique. Les deux matelas ainsi reliés sont agencés dans une housse de tissu. Dans un autre mode de réalisation, on pourra disposer deux matelas différents selon l'invention et les relier de la même façon par une bande adhésive comme un matériau scratch. Le matelas assemblé comportera ainsi un plus grand nombre de zones de repos qu'un matelas de l'invention seul.Furthermore, for a large mattress such as 160 centimeters in width, it is possible to use a single mattress or alternatively to arrange two identical mattresses according to the invention and to connect them together by an adhesive tape such as a scratch material or a tape. elastic device or with a common cover covering the two mattresses, the cover being preferably elastic. The two mattresses thus connected are arranged in a fabric cover. In another embodiment, may have two different mattresses according to the invention and connect them in the same way by an adhesive tape as a scratch material. The assembled mattress will thus comprise a greater number of resting areas than a mattress of the invention alone.

On peut ainsi réaliser de multiples combinaisons en fonctions des habitudes ou des désirs de l'utilisateur.It can thus achieve multiple combinations according to the habits or desires of the user.

Les couches externes et intermédiaire pourront être est en mousse souple, en mousse compacte, en mousse de polyuréthane haute densité, en mousse à mémoire de forme, en latex ou encore comprendre une ou des poches recevant des ressorts en métal, des ressorts en plastique, des ressorts en mousse, ou encore comprendre une ou des poches recevant de l'eau, de l'air, une ou des poches comprenant des lattes ... Si on utilise des ressorts, on pourra également jouer sur un diamètre des ressorts ou sur une hauteur desdits ressorts pour former des zones d'accueil aux caractéristiques mécaniques distinctes.The outer and intermediate layers may be made of flexible foam, compact foam, high-density polyurethane foam, memory foam, latex or include one or more pockets receiving metal springs, plastic springs, foam springs, or include one or pockets receiving water, air, one or pockets with slats ... If we use springs, we can also play on a diameter of the springs or on a height of said springs to form reception areas with distinct mechanical characteristics.

Les caractéristiques mécaniques de chaque zone d'accueil, conférées par les caractéristiques mécaniques des matériaux utilisés et la géométrie des différentes couches pourront concerner plusieurs aspects, comme la résilience, la souplesse, le temps de déformation sous charge...The mechanical characteristics of each reception zone, conferred by the mechanical characteristics of the materials used and the geometry of the different layers, may concern several aspects, such as resilience, flexibility, deformation time under load ...

En particulier, on pourra utiliser plus de trois couches, ou faire varier le nombre de couches sur la longueur du matelas.In particular, it will be possible to use more than three layers, or to vary the number of layers along the length of the mattress.

En référence à la figure 6, un matelas qui ne fait pas partie de l'invention comporte une première grande face principale 301 opposée à une deuxième grande face principale 302. Le matelas est ici subdivisé en deux portions dans le sens de sa grande longueur qui définissent :

  • au niveau de la première grande face principale 301, des zones d'accueil successives A1, A2 dont une succession A1 à A2 définit une première zone de repos et dont une succession inverse A2 à A1 définit une deuxième zone de repos ;
  • au niveau de la deuxième grande face principale, des zones d'accueil successives B1, B2 dont une succession B1 à B2 définit une troisième zone de repos et dont une succession inverse B2 à B1 définit une quatrième zone de repos.
With reference to the figure 6 a mattress which does not form part of the invention comprises a first large main face 301 opposed to a second large main face 302. The mattress is here subdivided into two portions in the direction of its great length which define:
  • at the level of the first large main face 301, successive reception areas A1, A2, one of which succession A1 to A2 defines a first rest zone and of which an inverse succession A2 to A1 defines a second rest zone;
  • at the level of the second large main face, successive reception areas B1, B2, a succession B1 to B2 defines a third rest zone and a reverse succession B2 to B1 defines a fourth rest zone.

Les quatre zones de repos présentent des profils d'accueil distincts, un utilisateur pouvant aisément trouver une zone de repos adaptée à sa morphologie et à ses besoins.The four rest areas have distinct home profiles, a user can easily find a rest area adapted to his morphology and his needs.

Pour obtenir ces profils d'accueil distincts, le matelas comporte ici :

  • une première couche externe 303 s'étendant pour former la première grande face principale 301, la première couche externe 303 étant ici constituée d'un premier bloc 306 et d'un deuxième bloc 307 se rejoignant au niveau d'une zone de jonction qui s'étend au niveau de la frontière entre la zone d'accueil A1 et la zone d'accueil A2
  • une deuxième couche externe 304 s'étendant pour former la deuxième grande face principale 302, la deuxième couche externe 304 étant ici constituée d'un premier bloc 308 et d'un deuxième bloc 309 se rejoignant au niveau d'une première zone de jonction qui s'étend au niveau de la frontière entre la zone d'accueil B1 et la zone d'accueil B2.
To obtain these distinct home profiles, the mattress has here:
  • a first outer layer 303 extending to form the first large main face 301, the first outer layer 303 being constituted by a first block 306 and a second block 307 joining at a junction zone which extends at the border between the reception area A1 and the reception area A2
  • a second outer layer 304 extending to form the second large main face 302, the second outer layer 304 being constituted by a first block 308 and a second block 309 joining at a first junction zone which extends at the border between the reception area B1 and the reception area B2.

Les deux blocs formant chacune des couches externes 303, 304 sont par exemple assemblés par collage ou par adhésion.The two blocks forming each of the outer layers 303, 304 are for example assembled by gluing or adhesion.

Les différents blocs constituant les couches externes 303, 304 sont réalisés dans des matériaux divers qui confèrent ainsi des caractéristiques mécaniques particulières aux différentes zones d'accueil par exemple en termes d'élasticité, de souplesse, de fermeté ...The different blocks constituting the outer layers 303, 304 are made of various materials which thus confer particular mechanical characteristics to the different reception areas for example in terms of elasticity, flexibility, firmness ...

Ces différences de caractéristiques mécaniques produisent quatre profils d'accueil qui sont bien distincts les uns des autres.These differences in mechanical characteristics produce four host profiles that are distinct from each other.

Enfin, bien que dans les exemples illustrés, chaque zone de repos est constituée d'une succession de sept zones d'accueil, ce nombre pourra bien sûr être différent. En particulier, on pourra ne définir que deux zones d'accueil sur chacune des faces principales du matelas. On pourra également réaliser des zones de repos dons les profils d'accueil varient continuement d'une zone d'accueil à une autre.Finally, although in the illustrated examples, each rest area consists of a succession of seven reception areas, this number may of course be different. In particular, it will be possible to define only two reception areas on each of the main faces of the mattress. It will also be possible to create rest areas in which the reception profiles vary continuously from one reception area to another.

La zone de jonction de deux blocs formant au moins une partie d'une couche externe et/ou de la couche intermédiaire pourra être réalisée au milieu d'une zone d'accueil. De préférence, une telle zone de jonction sera réalisée à la frontière de deux zones d'accueil consécutives afin d'améliorer le confort d'un utilisateur. De façon encore plus privilégiée, deux blocs consécutifs ne formeront pas une zone de jonction perpendiculaire aux grandes faces principales mais seront découpés de sorte à former une zone de jonction inclinée relativement à une perpendiculaire aux grandes faces principales (comme illustré à la figure 3). L'utilisateur ressentira moins de cette façon la zone de jonction ce qui améliora encore une fois le confort du patient.The junction zone of two blocks forming at least a portion of an outer layer and / or the intermediate layer may be formed in the middle of a reception area. Preferably, such a junction zone will be made at the border of two consecutive reception areas to improve the comfort of a user. Even more privileged, two consecutive blocks will not form a junction zone perpendicular to the major major faces but will be cut so as to form a junction zone inclined relative to a perpendicular to the major major faces (as illustrated in FIG. figure 3 ). The user will feel less in this way the junction area which will once again improve the comfort of the patient.

Lorsque la première couche externe est formée de deux blocs et la deuxième couche externe est formée également de deux blocs, la zone de jonction formée par les deux blocs de la première couche externe pourra s'étendre dans un même plan que la zone de jonction formée par les deux blocs de la deuxième couche externe. De préférence, la zone de jonction formée par les deux blocs de la première couche externe s'étendra dans un plan différent que la zone de jonction formée par les deux blocs de la deuxième couche externe (comme illustré à la figure 3bis). Ainsi, les deux zones de jonction seront décalées ce qui rendra le matelas dans son ensemble plus solide.When the first outer layer is formed of two blocks and the second outer layer is also formed of two blocks, the junction zone formed by the two blocks of the first outer layer may extend in the same plane as the junction zone formed by the two blocks of the second outer layer. Preferably, the junction zone formed by the two blocks of the first outer layer will extend in a different plane than the junction zone formed by the two blocks of the second outer layer (as illustrated in FIG. figure 3bis ). Thus, the two junction zones will be shifted which will make the mattress as a whole more solid.

Bien qu'ici l'élément de literie décrit soit un matelas, l'élément de literie pourra être différent. L'élément de literie pourra ainsi être un sur-matelas ou un sommier. Par exemple, dans les différents modes de réalisation et variantes décrits, le matelas pourra être d'une épaisseur suffisamment fine pour pouvoir être utilisé comme un sur-matelas. De préférence, le sur-matelas aura une épaisseur comprise entre 8 et 15 centimètres. Par exemple, dans les différents modes de réalisation et variantes décrits, le matelas pourra être formé d'une épaisseur suffisamment importante et composé de matériaux suffisamment ferme pour pouvoir être utilisé comme un sommier, un matelas traditionnel ou un matelas selon l'invention recouvrant alors ledit sommier.Although here the bedding element described is a mattress, the bedding element may be different. The bedding element can be a mattress or a mattress. For example, in the various embodiments and variants described, the mattress may be of a sufficiently thin thickness to be used as an over-mattress. Preferably, the over-mattress will have a thickness of between 8 and 15 centimeters. For example, in the various embodiments and variants described, the mattress may be formed of a sufficiently large thickness and made of materials sufficiently firm to be used as a bed base, a traditional mattress or a mattress according to the invention then covering said bed base.

Ainsi, la figure 7 représente un sommier comporte une première grande face principale 401 opposée à une deuxième grande face principale 402. Le sommier est ici subdivisé en trois portions dans le sens de sa grande longueur qui définissent :

  • au niveau de la première grande face principale 401, des zones d'accueil successives A1, A2, A3 dont une succession A1 à A3 définit une première zone de repos et dont une succession inverse A3 à A1 définit une deuxième zone de repos ;
  • au niveau de la deuxième grande face principale, des zones d'accueil successives B1, B3 dont une succession B1 à B3 définit une troisième zone de repos et dont une succession inverse B3 à B1 définit une quatrième zone de repos.
So, the figure 7 represents a bed base comprises a first large main face 401 opposite a second large main face 402. The bed is here subdivided into three portions in the direction of its great length which define:
  • at the level of the first major main face 401, successive reception areas A1, A2, A3 whose succession A1 to A3 defines a first rest zone and of which an inverse succession A3 to A1 defines a second rest zone;
  • at the level of the second large main face, successive reception areas B1, B3 whose succession B1 to B3 defines a third rest zone and whose an inverse succession B3 to B1 defines a fourth rest zone.

Selon l'invention, les quatre zones de repos présentent des profils d'accueil distincts, un utilisateur pouvant aisément trouver une zone de repos adaptée à sa morphologie et à ses besoins.According to the invention, the four rest areas have distinct home profiles, a user can easily find a rest area adapted to its morphology and its needs.

Pour obtenir ces profils d'accueil distincts, le matelas comporte ici :

  • une première couche externe 403 s'étendant pour former la première grande face principale 401, la première couche externe 403 étant ici constituée d'un premier bloc 406 et d'un deuxième bloc 407 se rejoignant au niveau d'une première zone de jonction qui s'étend au niveau de la frontière entre la zone d'accueil A1 et la zone d'accueil A2 et d'un troisième bloc 410 qui rejoint le deuxième bloc 407 au niveau d'une deuxième zone de jonction qui s'étend au niveau de la frontière entre la zone d'accueil A2 et la zone d'accueil A3 ;
  • une deuxième couche externe 404 s'étendant pour former la deuxième grande face principale 402, la deuxième couche externe 404 étant ici constituée d'un premier bloc 408 et d'un deuxième bloc 409 se rejoignant au niveau d'une première zone de jonction qui s'étend au niveau de la frontière entre la zone d'accueil B3 et la zone d'accueil B2 et d'un troisième bloc 411 qui rejoint le deuxième bloc 409 au niveau de la frontière entre la zone d'accueil B2 et la zone d'accueil B1.
  • et une couche intermédiaire 415 disposée entre les deux couches externes.
To obtain these distinct home profiles, the mattress has here:
  • a first outer layer 403 extending to form the first major main face 401, the first outer layer 403 being constituted by a first block 406 and a second block 407 joining at a first junction zone which extends at the boundary between the reception area A1 and the reception area A2 and a third block 410 which joins the second block 407 at a second connecting zone which extends to the border between the reception area A2 and the reception area A3;
  • a second outer layer 404 extending to form the second major main face 402, the second outer layer 404 being constituted by a first block 408 and a second block 409 joining at a first junction zone which extends at the border between the reception zone B3 and the reception zone B2 and a third block 411 which joins the second block 409 at the border between the reception zone B2 and the zone B1 home.
  • and an intermediate layer 415 disposed between the two outer layers.

Les trois blocs formant chacun des couches externes 403, 404 sont par exemple assemblés par collage ou par adhésion.The three blocks forming each of the outer layers 403, 404 are for example assembled by gluing or adhesion.

Les différents blocs constituant les couches externes 403, 404 sont réalisés dans des matériaux divers qui confèrent ainsi des caractéristiques mécaniques particulières aux différentes zones d'accueil par exemple en termes d'élasticité, de souplesse, de fermeté ...The different blocks constituting the outer layers 403, 404 are made of various materials which thus confer mechanical characteristics particular to the different reception areas for example in terms of elasticity, flexibility, firmness ...
