Description

L'invention concerne de manière générale les sommiers.The invention relates generally sommieres.

L'invention concerne plus particulièrement un sommier comprenant un cadre formant bâti, et une surface de couchage destinée à soutenir au moins le corps d'une personne. La surface de couchage est formée à partir d'éléments écartés et reliés entre eux par des lames longitudinales cintrables de manière à rendre les éléments déplaçables les uns par rapport aux autres suivant la forme des lames pour suivre la courbe des genoux et du dos de la personne en position assise de celle-ci sur la surface de couchage.The invention more particularly relates to a bed base comprising a frame frame, and a sleeping surface for supporting at least the body of a person. The sleeping surface is formed from elements spaced apart and interconnected by longitudinal blades that are bendable so as to make the elements movable relative to one another according to the shape of the blades to follow the curve of the knees and the back of the seated person of it on the sleeping surface.

On connaît de l'état de la technique et notamment du document FR2953699 déposé par la demanderesse, un lit à ligne continue. Ce lit comprend un sommier dont la surface de couchage est formée de panneaux reliés entre eux par des lames cintrables. Un autre sommier est connu du document EP1661495 A1 .It is known from the state of the art and in particular the document FR2953699 filed by the plaintiff, a continuous line bed. This bed comprises a bed base whose sleeping surface is formed of panels interconnected by bendable blades. Another box spring is known from the document EP1661495 A1 .

Cependant, l'utilisation de panneaux rend le sommier lourd. En outre, le système d'amortissement utilisé avec un tel sommier, dont la surface de couchage est composée de panneaux, est limité à une série de pains ou boudins de mousse disposés sur les panneaux.However, the use of panels makes the bed base heavy. In addition, the damping system used with such a bed base, whose sleeping surface is composed of panels, is limited to a series of loaves or foam rolls arranged on the panels.

Enfin, avec un tel sommier connu de l'état de la technique, la ventilation du matelas destiné à reposer sur la surface de couchage n'est pas optimale du fait que les panneaux s'étendent sur toute la surface de la surface de couchage.Finally, with such a bed base known from the state of the art, the ventilation of the mattress intended to rest on the sleeping surface is not optimal because the panels extend over the entire surface of the sleeping surface.

La présente invention a pour but de proposer un nouveau sommier permettant de résoudre tout ou parties des problèmes exposés ci-dessus.The present invention aims to provide a new bed base to solve all or part of the problems described above.

A cet effet, l'invention a pour objet un sommier conforme à la revendication 1For this purpose, the subject of the invention is a bed base according to claim 1

Grâce à une telle conception du sommier selon l'invention, la surface de couchage est relevable avec un profil sensiblement en forme de ligne régulière, tout en présentant un poids réduit. En outre, les deux séries de tronçons de poutre offrent la possibilité de construire la surface de couchage avec différents types de système d'amortissement comme détaillé ci-après. On entend par ligne régulière, une ligne sans pan cassé, de manière à épouser correctement le profil du corps de la personne étendue sur la surface de couchage via le matelas.Thanks to such a design of the bed base according to the invention, the sleeping surface is liftable with a profile substantially in the form of a regular line, while having a reduced weight. In addition, the two series of beam sections offer the possibility of constructing the sleeping surface with different types of damping system as detailed below. The term regular line, a line without broken pan, so as to marry correctly the profile of the body of the person lying on the sleeping surface via the mattress.

Le sommier selon l'invention améliore aussi les conditions de ventilation pour le matelas destiné à être positionné sur la surface de couchage, par l'intermédiaire des systèmes de suspension.The bed base according to the invention also improves the ventilation conditions for the mattress intended to be positioned on the sleeping surface, by means of the suspension systems.

Le fait de réaliser la structure principale de la surface de couchage, c'est-à-dire la structure qui reprend les efforts et qui est couplée au cadre, sous forme de deux séries de tronçons de poutre parallèles et écartées de l'autre série de tronçons de poutre, permet de ménager un espace au niveau duquel peuvent être disposés des systèmes de suspension reliant une série de tronçons de poutre à l'autre et disposés à écartement les uns des autres.The fact of realizing the main structure of the sleeping surface, that is to say the structure which takes the efforts and which is coupled to the frame, in the form of two series of parallel beam sections and separated from the other series of beam sections, allows to provide a space at which may be arranged suspension systems connecting a series of beam sections to each other and arranged spaced from each other.

Cet espace disponible entre les bords latéraux de la surface de couchage permet ainsi de rapporter différents systèmes de suspension puisque les éléments de la série de tronçons offrent des surfaces de fixation pour lesdits systèmes de suspension et que l'écartement entre les séries de tronçons libère un espace disponible pour l'étendue de ces systèmes de suspension.This space available between the lateral edges of the coating surface thus makes it possible to relate different suspension systems since the elements of the series of sections offer attachment surfaces for said suspension systems and that the spacing between the series of sections releases a plurality of suspension systems. space available for the extent of these suspension systems.

Ladite surface de couchage comprend deux lames 3 longitudinales de liaison cintrables qui s'étendent sensiblement parallèlement à la ligne longitudinale de la surface de couchage. Lesdites lames 3 sont écartées l'une de l'autre, suivant une direction orthogonale à la ligne longitudinale de la surface de couchage.Said coating surface comprises two longitudinally flexible connecting blades 3 which extend substantially parallel to the longitudinal line of the coating surface. Said blades 3 are spaced apart from each other, in a direction orthogonal to the longitudinal line of the coating surface.

Ledit sommier comprend, pour chaque lame cintrable 3, une série 2 d'éléments 210, 220, 230, 240, 250 rigides, appelée série de tronçons de poutre, fixés par vissage, le long de la lame cintrable 3 correspondante.Said bed base comprises, for each bendable blade 3, a series 2 of elements 210, 220, 230, 240, 250 rigid, called series of beam sections, fixed by screwing, along the corresponding bendable blade 3.

Lesdits éléments de la série sont alignés à écartement les uns des autres. Chaque lame cintrable 3 permet aux éléments de la série de tronçons de poutre fixés à ladite lame d'être déplacés les uns par rapport aux autres. Dans l'exemple illustré à la figure 1, une seule lame 3 a été représentée, mais la surface de couchage comprend bien une lame le long de chacun de ses bords latéraux définis par les deux séries de tronçons de poutre.Said elements of the series are aligned spaced from each other. Each bendable blade 3 allows the elements of the series of beam sections attached to said blade to be moved relative to each other. In the example shown in figure 1 , a single blade 3 has been shown, but the sleeping surface comprises a blade along each of its lateral edges defined by the two series of beam sections.

Chaque lame peut être réalisée d'un seul tenant ou formée de plusieurs pièces reliées entre elles par les éléments des séries de tronçons de poutre.Each blade can be made in one piece or formed of several parts interconnected by the elements of the series of beam sections.

Ladite surface de couchage présente au moins une zone centrale 130 support de fessier qui comprend au moins deux éléments tronçons opposés montés fixes par rapport au cadre 10. Cette zone centrale 130 est prolongée du côté avant du sommier par une zone de soutien des genoux 120 et de l'autre côté par une zone de soutien du dos 140.Said sleeping surface has at least one central area 130 for a gluteal support which comprises at least two opposite section elements fixedly mounted relative to the frame 10. This central zone 130 is extended on the front side of the bed base by a knee support zone 120 and on the other side by a back support area 140.

Lesdites zones de soutien des genoux 120 et de soutien du dos 140 sont aptes à être déplacées chacune entre, d'une part, une position abaissée sur le cadre 10, dans laquelle lesdites zones de soutien s'étendent parallèlement à, et dans le prolongement de, la zone centrale 130, en applique de la surface supérieure du cadre 10, et, d'autre part, une position relevée par rapport au cadre 10, dans laquelle lesdites zones de soutien sont au moins partiellement écartées de la surface supérieure du cadre 10 pour suivre la courbe des genoux et du dos de la personne en position assise de celle-ci le long de la surface de couchage.Said knee 120 and back support 140 areas are each able to be moved between, on the one hand, a lowered position on the frame 10, in which said support zones extend parallel to and in the extension of, the central zone 130, applied from the upper surface of the frame 10, and, on the other hand, a raised position relative to the frame 10, in which the said support zones are at least partially spaced from the upper surface of the frame 10 to follow the curve of the knees and the back of the person in the sitting position thereof along the sleeping surface.

La surface de couchage 100 comprend aussi une zone 110 de soutien des pieds, prolongeant la zone de soutien des genoux 120. Ladite zone 110 de soutien des pieds comprend deux éléments de longerons 210 reliés chacun à l'une des deux séries 2 de tronçons de poutre et reliés entre eux par une traverse 410.The sleeping surface 100 also includes a foot support zone 110, extending the knee support zone 120. Said foot support zone 110 comprises two elements of longitudinal members 210 each connected to one of the two series of foot sections. beam and interconnected by a cross 410.

La surface de couchage comprend aussi des systèmes de suspension 5 qui relient entre eux les éléments des deux séries 2 qui se font face. En particulier, certains des éléments de plus grande longueur et situés au niveau des zones de soutien du dos et des pieds sont reliés entre eux par plusieurs système de suspension.The sleeping surface also comprises suspension systems 5 which connect together the elements of the two series 2 which face each other. In particular, some of the elements of greater length and located at the support zones of the back and feet are interconnected by several suspension system.

La surface de couchage comprend aussi au moins une zone de soutien de la tête, appelée têtière 150, et une structure télescopique 154 de liaison à la zone de soutien du dos 140. Ladite têtière 150 comprend deux éléments de longerons 250 reliés entre eux par des traverses 450 et un système de suspension 5 qui s'étend entre et se reprend sur les deux éléments de longerons 250 opposés.The sleeping surface also comprises at least one head support zone, called a headrest 150, and a telescopic linkage structure 154 back support 140. Said headrest 150 comprises two members of longitudinal members 250 interconnected by cross members 450 and a suspension system 5 which extends between and is taken up on the two elements of opposite side members 250.

Ledit sommier comprend au moins un système de levage 6 des zones de soutien des pieds 110 et des genoux 120, et un système de levage 8 de la zone de soutien 140 du dos.Said bed base comprises at least one lifting system 6 of the support zones of the feet 110 and knees 120, and a lifting system 8 of the support zone 140 of the back.

Ledit sommier comprend aussi des traverses 410, 420, 430, 440, 450 qui s'étendent d'une série 2 de tronçons de poutre à l'autre 2. Chaque extrémité d'une traverse est solidarisée à un élément de la série 2 de tronçons correspondante.Said bed base also comprises crosspieces 410, 420, 430, 440, 450 which extend from a series 2 of beam sections to the other 2. Each end of a cross member is secured to an element of the series 2 of corresponding sections.

La traverse 410 s'étend au niveau de l'extrémité libre de la zone de soutien des pieds 110. Les traverses 420, 430 s'étendent au niveau respectivement de l'extrémité de la zone de soutien des genoux 120 située du côté de la zone de soutien des pieds 110 et de l'extrémité de la zone de soutien des genoux 120 située du côté de la zone de soutien du fessier 130. Les traverses 440 sont situées du côté de l'extrémité supérieure de la zone de soutien de dos 140 et forment une structure support pour un système de liaison télescopique 154 entre la têtière 150 et la zone de soutien du dos 140.The crosspiece 410 extends at the free end of the support zone of the feet 110. The cross members 420, 430 extend respectively at the end of the knee support zone 120 located on the side of the support area of the feet 110 and the end of the knee support zone 120 located on the side of the buttock support area 130. The sleepers 440 are located on the side of the upper end of the back support zone 140 and form a support structure for a telescopic linkage system 154 between the headrest 150 and the back support area 140.

Chacun des éléments de la série 2 de tronçons de poutre présente une forme générale parallélépipédique, et, de préférence, allongée suivant la direction de la lame cintrable 3 à laquelle il est fixé.Each of the elements of the series 2 of beam sections has a generally parallelepipedic shape, and preferably elongated in the direction of the bendable blade 3 to which it is attached.

Lesdits éléments formant chaque série de tronçons de poutre présentent chacun une largeur de l'ordre de 48 millimètres. Cette largeur est de préférence comprise entre 40 et 100 millimètres. Avantageusement, la largeur de la série de tronçons de poutre est inférieure à deux fois la largeur de la lame, mais supérieure ou égale à la largeur de la lame. La largeur de la lame est de l'ordre de 30 millimètres.Said elements forming each series of beam sections each have a width of the order of 48 millimeters. This width is preferably between 40 and 100 millimeters. Advantageously, the width of the series of beam sections is less than twice the width of the blade, but greater than or equal to the width of the blade. The width of the blade is of the order of 30 millimeters.

Chaque élément d'une série 2 de tronçons de poutre comprend une face latérale intérieure, c'est-à-dire orientée vers la face intérieure d'un élément de l'autre série en vis-à-vis de laquelle elle s'étend.Each element of a series 2 of beam sections comprises an inner side face, that is to say, oriented towards the inner face of one element of the other series vis-à-vis which it extends .

Comme détaillé ci-après, chaque système de suspension comprend une structure de liaison couplée aux faces latérales intérieures de deux éléments opposés des séries 2 de tronçons de poutre entre lesquels ledit système de suspension 5 s'étend.As detailed below, each suspension system comprises a connecting structure coupled to the inner side faces of two opposite members of the series 2 of beam sections between which said suspension system 5 extends.

Chaque lame cintrable 3 s'étend dans l'épaisseur, prise hors tout, c'est-à-dire entre la cote la plus basse et la cote la plus haute de chaque élément. L'épaisseur hors tout de chaque élément de série de tronçons est de préférence comprise entre 30 millimètres et 40 millimètres. Dans l'exemple illustré aux figures, l'épaisseur hors-tout de chaque élément de série de tronçons est de l'ordre de 30 millimètres.Each bendable blade 3 extends in thickness, taken over all, that is to say between the lowest dimension and the highest dimension of each element. The overall thickness of each series element of sections is preferably between 30 millimeters and 40 millimeters. In the example illustrated in the figures, the overall thickness of each series of sections element is of the order of 30 millimeters.

Dans l'exemple illustré aux figures, une échancrure est ménagée le long de chacun des éléments de chaque série de tronçons de poutre de sorte que la lame cintrable correspondante s'étend du côté de la face de dessous de ladite série d'éléments, par opposition à la face de dessus orientée vers le matelas destiné à être posé sur la surface de couchage.In the example illustrated in the figures, a notch is formed along each of the elements of each series of beam sections so that the corresponding bendable blade extends on the side of the bottom face of said series of elements, by opposed to the top face facing the mattress to be placed on the sleeping surface.

Chaque bord latéral de la surface de couchage 100 est formé par l'assemblage d'une des lames cintrables 3 avec la série 2 de tronçons de poutre correspondante.Each side edge of the coating surface 100 is formed by the assembly of one of the bendable blades 3 with the series 2 of corresponding beam sections.

Comme illustré à la figure 3, chaque ensemble formé d'une lame cintrable 3 et d'une série 2 de tronçons de poutre et formant ainsi un bord latéral de la surface de couchage, est revêtu d'un élément allongé élastiquement déformable 7, appelé chaussette, permettant de masquer ledit ensemble.As illustrated in figure 3 each assembly formed of a bendable blade 3 and a series 2 of beam sections and thus forming a lateral edge of the coating surface, is coated with an elongated elastically deformable element 7, called a sock, which makes it possible to mask said together.

Dans l'exemple illustré aux figures 1 à 7, chaque système de suspension 5 comprend au moins une latte 51, de préférence trois lattes parallèles, couplée(s) à ses ou à leurs extrémités à deux organes de liaison 52. Lesdits deux organes de liaison 52 sont fixés, de préférence par vissage, l'un à un élément d'une des séries 2 de tronçons de poutre et l'autre à un élément de la série 2 de tronçons de poutre opposée. D'autres moyens de fixation, par exemple par encliquetage, sont envisageables.In the example shown in Figures 1 to 7 , each suspension system 5 comprises at least one slat 51, preferably three parallel slats, coupled to its or their ends with two connecting members 52. Said two connecting members 52 are fixed, preferably by screwing, one to an element one of the series 2 of beam sections and the other to an element of the series 2 of sections of opposite beam. Other fastening means, for example snap-fastening, are conceivable.

Chaque organe de liaison 52 présente de préférence une forme générale en V déformable. L'extrémité d'une branche du V est fixée à un élément de la série 2 de tronçons de poutre correspondante et l'extrémité de l'autre branche est reliée à la ou aux lattes 51.Each connecting member 52 preferably has a generally deformable V shape. The end of a branch of the V is fixed to a member of the series 2 of corresponding beam sections and the end of the other branch is connected to the slat or slats 51.

Selon une variante de réalisation illustrée à la figure 8, les systèmes de suspension situés au niveau des zones de soutien de dos, de soutien de fessier et de soutien des genoux, sont remplacés par des systèmes de suspension 5' qui comprennent chacun une barre support 51' s'étendant transversalement d'une série 2 de tronçons de poutre à l'autre 2. Plusieurs organes de suspension 52' sont répartis le long de la barre support 51' de chaque système de suspension.According to an embodiment variant illustrated in figure 8 the suspension systems located at the level of the back support, gluteal support and knee support areas are replaced by suspension systems 5 'which each comprise a support bar 51' extending transversely of a series 2 of the beam sections to the other 2. Several suspension members 52 'are distributed along the support bar 51' of each suspension system.

Différents systèmes de suspension peuvent être rapportés sur les éléments des deux séries de tronçons de poutre pour former la surface de couchage.Different suspension systems can be reported on the elements of the two sets of beam sections to form the sleeping surface.

Au moins en configuration abaissée de la surface de couchage comme illustré aux figures 4 et 5, les éléments de chaque série de tronçons de poutre sont écartés les uns des autres, de préférence d'une distance de l'ordre de 2 cm.At least in the lowered configuration of the sleeping surface as illustrated in figures 4 and 5 , the elements of each series of beam sections are spaced from each other, preferably a distance of about 2 cm.

Chaque lame de liaison cintrable s'étend suivant la ligne longitudinale de la surface de couchage, à savoir l'axe longitudinal du cadre à l'état abaissé de la surface de couchage contre le cadre.Each bendable connecting strip extends along the longitudinal line of the coating surface, namely the longitudinal axis of the frame in the lowered state of the coating surface against the frame.

La ou chaque lame longitudinale de liaison cintrable est configurée pour permettre aux éléments des séries de tronçons de poutre, d'être déplacés à pivotement les uns par rapport aux autres par flexion, ou cintrage, de la ou de chaque lame cintrable, autour d'un axe de pivotement instantané perpendiculaire à l'axe longitudinal de ladite lame. Lesdits éléments des séries de tronçons de poutre sont dépourvus entre eux de liaisons mécaniques articulées, qui seraient formées de pièces mobiles rigides. La ou chaque lame cintrable permet d'accompagner, par flexion de ladite lame, les déplacements à pivotement des éléments les uns par rapport aux autres.The or each longitudinal blade of bendable connection is configured to allow the elements of the series of beam sections to be moved to pivoting relative to each other by bending, or bending, the or each bendable blade, about an instantaneous pivot axis perpendicular to the longitudinal axis of said blade. Said elements of the series of beam sections are lacking articulated mechanical links between them, which would be formed of rigid moving parts. The or each bendable blade allows to accompany, by bending of said blade, the pivotal movements of the elements relative to each other.

Ainsi, chaque lame longitudinale de liaison cintrable, c'est-à-dire flexible, joue le rôle d'une colonne vertébrale reliant les éléments rigides qui forment les vertèbres de ladite colonne.Thus, each longitudinal blade of flexible connection, that is to say flexible, plays the role of a spinal column connecting the rigid elements that form the vertebrae of said column.

Les systèmes de suspension qui relient entre eux les éléments des deux série de tronçons opposées sont répartis selon la ligne longitudinale du sommier et s'étendent transversalement par rapport à ladite ligne longitudinale, c'est-à-dire transversalement à la ou chaque lame cintrable.The suspension systems that connect together the elements of the two series of opposite sections are distributed along the longitudinal line of the bed base and extend transversely with respect to said longitudinal line, that is to say transversely to the or each bendable blade .

Une telle conception du sommier permet à la surface de couchage relevable de présenter un profil en ligne continue de courbure régulière à l'état relevé d'au moins une zone de la surface de couchage, en particulier à l'état relevé de la zone de soutien des genoux et/ou de la zone de soutien du dos.Such a bed base design allows the loftable sleeping surface to have a continuous line profile of regular curvature in the raised state of at least one area of the sleeping surface, particularly in the raised condition of the sleeping area. knee support and / or back support area.

La surface de couchage présente ainsi des évidements qui rendent sa structure légère et permettent une meilleure circulation de l'air à travers au niveau du matelas destiné à reposer dessus par l'intermédiaire des systèmes de suspension.The sleeping surface thus has recesses which make its structure light and allow better air circulation through the mattress intended to rest on it through the suspension systems.

Dans l'exemple illustré aux figures, les lames de liaison cintrables 3 relient entre elles les zones de soutien 110, 120, 130, 140 des pieds au dos, mais pas la têtière 150.In the example illustrated in the figures, the flexible connecting strips 3 connect together the support zones 110, 120, 130, 140 from the feet to the back, but not the headrest 150.

Les lames de liaison 3 sont de préférence fixées aux éléments de série de tronçons côté face de dessous desdits tronçons pour obtenir un meilleur comportement mécanique desdites lames. En effet, dans cette configuration, les lames 3 sont poussées contre les éléments de la série de tronçons lors du relèvement des zones de soutien des genoux et/ou du dos.The connecting strips 3 are preferably attached to the series elements of sections on the underside side of said sections to obtain a better result. mechanical behavior of said blades. Indeed, in this configuration, the blades 3 are pushed against the elements of the series of sections when raising the support zones of the knees and / or back.

Les lames de liaison cintrables 3 sont réalisées, dans l'exemple illustré aux figures, en acier inoxydable. En variante, on peut prévoir de les réaliser en fibres de verre ou en carbone.The bendable connecting blades 3 are made in the example illustrated in the figures, stainless steel. Alternatively, it can be provided to make them in glass fibers or carbon.

La fixation des lames 3, en particulier par vissage, aux tronçons permet d'éviter un glissement des lames 3 par rapport aux tronçons lors des déplacements relatifs des tronçons entre eux.The fixing of the blades 3, in particular by screwing, with the sections makes it possible to prevent the blades 3 from sliding relative to the sections during the relative displacements of the sections between them.

Dans l'exemple illustré aux figures, le sommier est équipé de deux systèmes de relevage 6 des zones de soutien des pieds et des genoux et d'organes de relevage 8 de la têtière 150. Le relevage de la têtière permet également de relever la zone de soutien du dos 140.In the example illustrated in the figures, the bed base is equipped with two lifting systems 6 of the support zones of the feet and knees and lifting members 8 of the headrest 150. The raising of the headrest also makes it possible to raise the area back support 140.

A l'état relevé de la zone de soutien du dos et/ou de la zone de soutien des genoux, les lames longitudinales cintrables, qui relient entre eux les éléments des séries de tronçons de poutre, forment des articulations souples dépourvues de pièces rigides mobiles, ce qui leur permet de présenter une courbure continue régulière lorsque les éléments rigides sont déplacés les uns par rapport aux autres.In the raised state of the support zone of the back and / or the knee support zone, the bendable longitudinal blades, which connect together the elements of the series of beam sections, form flexible hinges devoid of moving rigid parts. which allows them to have a regular continuous curvature when the rigid elements are moved relative to each other.

La présence des lames cintrables le long des séries de tronçons de poutre qui définissent les bords latéraux de la surface de couchage et une structure support pour les système de suspension, permet d'éviter l'apparition de pans cassés au niveau de la courbe formée par le profil de la surface de couchage en position relevée des zones de soutien des genoux et/ou du dos.The presence of the bendable blades along the series of beam sections that define the lateral edges of the coating surface and a support structure for the suspension system, makes it possible to avoid the appearance of broken sections at the curve formed by the profile of the sleeping surface in the raised position of the support areas of the knees and / or the back.

En effet, le déplacement relatif des éléments rigides de chaque série entre eux s'accompagne de la déformation par flexion des lames cintrables, autour d'un axe parallèle au plan du cadre et orthogonal à l'axe longitudinal du cadre, ce qui permet à la surface de couchage du sommier d'épouser au mieux la courbure du matelas et donc la morphologie de la personne couchée sur le matelas.Indeed, the relative displacement of the rigid elements of each series between them is accompanied by the bending deformation of the bendable blades, about an axis parallel to the plane of the frame and orthogonal to the longitudinal axis of the frame, this which allows the sleeping surface of the bed base to marry at best the curvature of the mattress and thus the morphology of the person lying on the mattress.

Quelle que soit la position, abaissée ou relevée, des zones de soutien des genoux et/ou du dos, la surface de couchage offre un profil régulier qui correspond à une courbe dont la dérivée d'ordre 1 est continue, ce qui permet à la surface de couchage d'épouser efficacement le profil du matelas et de la personne pour améliorer son confort.Whatever the position, lowered or raised, knee and / or back support areas, the sleeping surface provides a regular profile that corresponds to a curve whose derivative of order 1 is continuous, allowing the sleeping surface to effectively marry the profile of the mattress and the person to enhance comfort.
