Description

La présente invention concerne un dispositif de suspension apte à s'étendre entre les longerons d'un cadre de sommier ou de lit en vue de supporter un matelas.The present invention relates to a suspension device adapted to extend between the longitudinal members of a bed frame or bed to support a mattress.

Elle concerne plus particulièrement un dispositif de suspension comprenant au moins une semelle support de matelas, au moins une traverse support de ladite semelle et des éléments amortisseurs disposés entre traverse et semelle, lesdits éléments amortisseurs étant déformables par compression dans le sens d'un rapprochement de la semelle de la au moins une traverse support.It relates more particularly to a suspension device comprising at least one mattress support pad, at least one support beam of said pad and damping elements arranged between cross and sole, said damping elements being deformable by compression in the direction of a closer the sole of the at least one cross support.

Un tel dispositif de suspension est d'ores et déjà connu du brevet FR 2.914.164 . Dans un tel dispositif, la déformation sous charge s'opère à l'intérieur d'une plage limitée et de manière non progressive.Such a suspension device is already known from the patent FR 2,914,164 . In such a device, the deformation under load takes place within a limited range and in a non-progressive manner.

Un but de la présente invention est de proposer un dispositif de suspension du type précité dont la conception permet une déformation de manière progressive sur une large plage du dispositif avec, par exemple, une phase dite d'accueil de la personne en train de se coucher au cours de laquelle la déformation s'opère sur une faible plage de manière aisée, suivie d'une phase dite de soutien au cours de laquelle la déformation s'opère sur une plus grande plage tout en offrant une résistance à la déformation plus importante.An object of the present invention is to provide a suspension device of the aforementioned type whose design allows a gradual deformation over a wide range of the device with, for example, a so-called phase of reception of the person going to bed during which the deformation operates on a small range easily, followed by a so-called support phase during which the deformation operates over a larger range while providing greater resistance to deformation.

A cet effet, l'invention a pour objet un dispositif de suspension apte à s'étendre entre les longerons d'un cadre de sommier ou de lit en vue de supporter un matelas, ledit dispositif comprenant au moins une semelle support de matelas, au moins une traverse support de ladite semelle et des éléments amortisseurs disposés entre traverse(s) et semelle, lesdits éléments amortisseurs étant déformables par compression dans le sens d'un rapprochement de la semelle de la au moins une traverse support, caractérisé en ce que la semelle support de matelas est formée d'une pluralité d'éléments individuels disposés côte à côte, chaque élément individuel de semelle comprenant au moins un plateau avec une face du dessus, dite active, support de matelas et, côté face du dessous, au moins une zone de liaison dudit plateau support à un élément amortisseur, la ou au moins l'une des zone(s) de liaison, réalisée d'une seule pièce avec ledit plateau, étant une zone élastiquement déformable apte à se déformer dans le sens d'un rapprochement dudit plateau de la au moins une traverse support sous l'effet d'une charge d'appui appliquée sur la face active dudit plateau, ladite zone de liaison étant configurée pour, sous l'effet de ladite charge d'appui, se déformer avant l'élément amortisseur auquel ladite zone de liaison est solidarisée.To this end, the invention relates to a suspension device adapted to extend between the longitudinal members of a bed frame or bed to support a mattress, said device comprising at least one mattress support sole, to at least one support beam of said sole and damping elements arranged between cross-member (s) and sole, said damping elements being deformable by compression in the direction of approaching the sole of the at least one cross support, characterized in that the support sole of mattresses is formed of a plurality of individual elements arranged side by side, each individual sole element comprising at least one plate with a face of the above, said active, mattress support and, on the underside, at least one zone connecting said support plate to a damping element, the or at least one of the zone (s) of connection, made in one piece with said plate, being an elastically deformable zone able to deform in the direction of a approaching said plate of the at least one support beam under the effect of a bearing load applied to the active face of said plate, said connecting zone being configured, under the effect of said support load, to deform before the damping element to which said connecting zone is secured.

Par charge d'appui appliquée sur la face active du plateau, on entend une force de poussée exercée sur la face active du plateau suivant une direction normale audit plateau.By pressing load applied to the active face of the plate is meant a thrust force exerted on the active face of the plate in a direction normal to said plate.

De préférence, la ou au moins l'une des zone(s) de liaison élastiquement déformable dudit plateau support à un élément amortisseur est formée d'une base de raccordement de la zone de liaison à l'élément amortisseur et de deux bras reliés à l'une de leurs extrémités par une zone d'affaiblissement ou d'amincissement à ladite base de raccordement et se raccordant à l'autre de leurs extrémités au plateau support, lesdits bras formant entre eux un V à l'état non sollicité de la face active du plateau et étant aptes à former un V inversé à l'état sollicité de la face active du plateau par une charge d'appui de poids supérieur à une valeur prédéterminée.Preferably, the or at least one of the elastically deformable connecting zone (s) of said support plate to a damping element is formed of a connection base of the zone of connection to the damping element and of two arms connected to one of their ends by a zone of weakening or thinning at said connection base and connecting at the other end of their support plate, said arms forming between them a V in the unsolicited state of the active face of the plate and being able to form an inverted V in the stressed state of the active face of the plate by a support load of weight greater than a predetermined value.

Cette conception permet un encombrement réduit en hauteur de la zone de liaison, en particulier dans le cas d'un plateau convexe dont la face convexe est formée par la surface du dessus du plateau puisque la zone de liaison est au moins partiellement logée à l'intérieur du creux de l'arc formé par ladite semelle.This design allows a reduced size in height of the connecting zone, in particular in the case of a convex plate whose convex face is formed by the top surface of the plate since the connecting zone is at least partially housed at the interior of the hollow of the arc formed by said sole.

En effet, de préférence, le plateau de chaque élément individuel de semelle est un plateau à face du dessus convexe, et à face du dessous concave, au moins une partie de la ou des zones de liaison du plateau à un élément amortisseur étant logée à l'intérieur du creux formé par la face du dessous concave.In fact, preferably, the plate of each individual sole member is a face-to-face plate convex, and concave underside face, at least a portion of the connection zone or zones of the plate to a damping element being housed at inside the hollow formed by the concave underside.

Les bras sont aptes, du fait de leur raccordement à la base de raccordement par une zone d'affaiblissement ou d'amincissement, à passer, sous l'effet d'une charge d'appui sur la face active du plateau, d'une position dans laquelle ils s'étendent au-dessus de la base et divergent depuis la base de raccordement pour former un V entre eux, à une position dans laquelle ils s'étendent au-dessous de la base de raccordement et divergent depuis la base de raccordement pour former un V inversé.The arms are capable, because of their connection to the connection base by a zone of weakening or thinning, to pass, under the effect of a bearing load on the active face of the plate, a position in which they extend above the base and diverge from the connection base to form a V between them at a position in which they extend below the connection base and diverge from the base of the connection to form an inverted V.

Cette déformation s'opère à l'état sollicité de la face active du plateau par une charge d'appui telle que le poids d'une personne susceptible de s'allonger ou de s'asseoir sur le matelas reposant au moins localement sur le dispositif de suspension.This deformation takes place in the stressed state of the active face of the plate by a support load such as the weight of a person likely to lie down or sit on the mattress resting at least locally on the device suspension.

De préférence, les bras de la zone de liaison sont, en position extrême de déformation de ladite zone de liaison sous charge, en position d'appui sur l'élément amortisseur.Preferably, the arms of the connecting zone are, in the extreme position of deformation of said bonding zone under load, in a bearing position on the damping element.

La course des bras est ainsi limitée par l'élément amortisseur qui assure le relais de la déformation du dispositif de suspension et forme un deuxième niveau de suspension à un ou plusieurs étages.The stroke of the arms is thus limited by the damping element which ensures the relay of the deformation of the suspension device and forms a second level of suspension at one or more stages.

En effet, chaque élément amortisseur est formé d' au moins un corps élastiquement déformable comprenant une structure tubulaire ou une pluralité de structures tubulaires superposées organisées chacune, de préférence, autour d'un axe parallèle à l'axe longitudinal de la ou d'une traverse support, ledit corps étant muni, à sa base, d'au moins un organe de liaison à la ou une traverse support et, à son sommet, de moyens de solidarisation à la ou une zone de liaison du plateau support de matelas.Indeed, each damping element is formed of at least one elastically deformable body comprising a tubular structure or a plurality of superimposed tubular structures each preferably organized around an axis parallel to the longitudinal axis of the or a support beam, said body being provided, at its base, with at least one connecting member to the support beam or cross member and, at its top, securing means to the one or a connecting area of the mattress support tray.

Lorsque le corps de l'élément amortisseur comporte une pluralité de structures tubulaires superposées, l'amortissement s'opère par déformation d'une ou plusieurs structures tubulaires selon la valeur de la charge d'appui exercée sur la face active du plateau.When the body of the damping element comprises a plurality of superposed tubular structures, the damping is effected by deformation of one or more tubular structures according to the value of the bearing load exerted on the active face of the plate.

De préférence, la structure tubulaire du corps d'élément amortisseur solidarisée à la ou une zone de liaison du plateau support de matelas affecte la forme d'un losange à sommet aplati dans sa zone de solidarisation à la zone de liaison, les côtés du losange jouxtant ledit sommet étant aptes à former des butées de fin de course d'au moins une partie de la zone de liaison en position extrême de déformation de ladite zone de liaison à l'état sollicité de la face active du plateau par une charge d'appui.Preferably, the tubular structure of the damping element body secured to the or a connecting zone of the mattress support plate has the shape of a rhombus with a flattened crown in its zone of attachment to the connection zone, the sides of the rhombus adjoining said vertex being able to form end stops of at least a portion of the connection zone in the extreme position of deformation of said connection zone in the stressed state of the active face of the plate by a load of support.

De préférence, l'organe de liaison du ou d'un corps de l'élément amortisseur à la, ou au moins une, traverse support affecte la forme d'un anneau accolé par sa surface périphérique externe au pourtour périphérique du corps de l'élément amortisseur, la traverse support étant enfilée dans ledit anneau.Preferably, the connecting member of the or of a body of the damping element at the, or at least one, crosspiece support has the shape of a ring attached by its outer peripheral surface to the peripheral periphery of the body of the damper element, the support beam being threaded into said ring.

Généralement, chaque plateau support de matelas comporte au moins deux zones de liaison dudit plateau à un élément amortisseur et chaque élément amortisseur comporte au moins deux corps entretoisés et solidarisés chacun à une zone de liaison d'un plateau support.Generally, each mattress support plate comprises at least two zones of connection of said plate to a damping element and each damping element comprises at least two bodies braced and each secured to a connection zone of a support plate.

Les ensembles formés chacun d'une zone de liaison et d'un corps s'étendent de part et d'autre d'un plan dit vertical passant par un axe parallèle à l'axe longitudinal de la ou des traverses support et par la zone sensiblement médiane de chaque plateau de la semelle support.The assemblies each formed of a connecting zone and of a body extend on either side of a so-called vertical plane passing through an axis parallel to the longitudinal axis of the support crossmember (s) and by the zone substantially median of each plate of the support sole.

Généralement, le dispositif comporte au moins deux traverses support parallèles et l'élément amortisseur comporte au moins deux corps équipés chacun d'un organe de liaison à une traverse support.Generally, the device comprises at least two parallel support rails and the damping element comprises at least two bodies equipped with each of a connecting member to a support cross.

De préférence, les moyens de solidarisation de l'élément amortisseur à la, ou au moins une, zone de liaison du plateau support de matelas sont des moyens de solidarisation par rivetage.Preferably, the means for securing the damping element to the or at least one connecting zone of the mattress support plate are riveting fastening means.

L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels :

  • La figure 1 représente une vue en perspective d'un dispositif de suspension conforme à l'invention ;

The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
  • The figure 1 represents a perspective view of a suspension device according to the invention;
  • The figure 2 is a perspective view of an assembly comprising an individual mattress support base element, a damping element and a support beam partially shown;
  • The Figures 3 to 6 represent cross-sectional views of the suspension device during its passage from the undeformed rest position corresponding to the unsolicited state of the active face of the plate by a support load to a deformed position under the effect a support load, such as the weight of a person lying down or sitting on a mattress resting at least locally on said device.

Comme mentionné ci-dessus, le dispositif 1 de suspension, objet de l'invention, est destiné à s'étendre entre les longerons d'un cadre de sommier ou de lit en vue de supporter un matelas. Les longerons du cadre de sommier ou de lit n'ont pas été représentés.As mentioned above, the suspension device 1, object of the invention, is intended to extend between the longitudinal members of a bed frame or bed to support a mattress. The rails of the bed frame or bed frame have not been shown.

Généralement, un cadre de sommier ou de lit comporte plusieurs dispositifs de suspension parallèles entre eux et écartés l'un de l'autre le long de l'axe longitudinal du lit, chaque dispositif de suspension s'étendant entre deux longerons en les reliant entre eux.Generally, a bed frame or bed comprises several suspension devices parallel to each other and spaced apart from each other along the longitudinal axis of the bed, each suspension device extending between two longitudinal members connecting them between them.

Chaque dispositif 1 de suspension comprend au moins une semelle 2 support de matelas, une traverse 3 support de ladite semelle 2 disposée au-dessous de la semelle et parallèlement à l'axe longitudinal de la semelle et des éléments 4 amortisseurs déformables par compression disposés entre traverse 3 et semelle 2.Each suspension device 1 comprises at least one mattress support flange 2, a support beam 3 for said flange 2 disposed beneath the flange and parallel to the longitudinal axis of the flange and compression-deformable damping elements 4 arranged between crossbar 3 and sole 2.

De manière caractéristique à l'invention, la semelle 2 support de matelas est formée d'une pluralité d'éléments 5 individuels disposés côte à côté d'une extrémité à une autre de ladite semelle. Chaque élément 5 individuel de semelle comprend au moins un plateau 6 avec une face 61 du dessus, dite active, support de matelas et une face 62 du dessous présentant au moins une zone 7 de liaison du plateau 6 support à un élément 4 amortisseur. Cette zone 7 de liaison réalisée d'une seule pièce avec ledit plateau 6 et disposée en saillie de la face 62 du dessous du plateau 6 est une zone élastiquement déformable apte à se déformer dans le sens d'un rapprochement dudit plateau 6 de la, ou au moins une traverse 3 support, sous l'effet d'une charge d'appui appliquée sur la face 61 active du plateau 6.Characteristically to the invention, the mattress support pad 2 is formed of a plurality of individual members disposed side-by-side from one end to another of said pad. Each individual sole element comprises at least one plate 6 with a face 61 of the above, said active, mattress support and a face 62 of the bottom having at least one zone 7 connecting the support plate 6 to a damping element 4. This connecting zone 7 made in one piece with said plate 6 and arranged projecting from the face 62 of the underside of the plate 6 is an elastically deformable zone capable of deforming in the direction of approaching said plate 6 of the, or at least one crosspiece 3 under the effect of a bearing load applied to the active face 61 of the plate 6.

La zone 7 de liaison est configurée pour, sous l'effet de ladite charge d'appui, se déformer avant l'élément amortisseur auquel la zone 7 de liaison est solidarisée.The connecting zone 7 is configured, under the effect of said support load, to deform before the damping element to which the connecting zone 7 is secured.

Dans les exemples représentés, chaque élément 5 individuel de semelle comprend un plateau 6 avec deux zones 7 de liaison du plateau à un élément 4 amortisseur, ces zones 7 de liaison élastiquement déformables étant réalisées d'une seule pièce avec ledit plateau 6.In the examples shown, each individual sole element comprises a plate 6 with two zones 7 for connecting the plate to a damping element 4, these elastically deformable connecting zones 7 being made in one piece with said plate 6.

Ces zones de liaison sont formées chacune d'une base 8 de raccordement de la zone 7 de liaison à l'élément 4 amortisseur et de deux bras 9 reliés à l'une de leurs extrémités par une zone 10 d'affaiblissement ou d'amincissement à ladite base 8 de raccordement et se raccordant à l'autre de leurs extrémités au plateau 6 support. Lesdits bras 9 forment entre eux un V à l'état non sollicité de la face 61 active du plateau 6 et sont aptes à former un V inversé à l'état sollicité de la face active du plateau 6 par une charge d'appui de poids supérieur à une valeur prédéterminée, ladite valeur étant fonction notamment de la conception de la zone d'amincissement.These connection zones are each formed of a base 8 connecting the zone 7 of connection to the damping element 4 and two arms 9 connected at one of their ends by a zone 10 of weakening or thinning at said base 8 of connection and connecting at the other end of their tray 6 support. Said arms 9 form between them a V in the unstressed state of the active face 61 of the plate 6 and are able to form an inverted V in the stressed state of the active face of the plate 6 by a weight bearing load greater than a predetermined value, said value being a function in particular of the design of the thinning zone.

La base 8 de raccordement se présente sous forme d'une platine venant en appui contre une face plane correspondante de l'élément amortisseur. Cette platine est ici munie d'un orifice traversant dont le rôle sera décrit ci-après.The base 8 of connection is in the form of a plate bearing against a corresponding flat face of the damping element. This plate is here provided with a through hole whose role will be described below.

Les bras 9 de la zone 7 de liaison sont, en position extrême de déformation de ladite zone 7 de liaison sous charge, en position d'appui sur l'élément 4 amortisseur.The arms 9 of the connecting zone 7 are, in the extreme position of deformation of said bonding zone 7 under load, in the bearing position on the damping element 4.

Chaque élément 4 amortisseur est, quant à lui, formé d'au moins un corps 11 élastiquement déformable comprenant une structure 12 tubulaire ou une pluralité de structures 12 tubulaires superposées organisées chacune, de préférence, autour d'un axe parallèle à l'axe longitudinal de la ou d'une traverse 3 support, ledit corps 11 étant muni, à sa base 8, d'au moins un organe 13 de liaison à la ou une traverse 3 support et, à son sommet, de moyens 14 de solidarisation à la ou une zone 7 de liaison du plateau 6 support de matelas.Each element 4 damper is, for its part, formed of at least one elastically deformable body 11 comprising a tubular structure 12 or a plurality of superimposed tubular structures 12 each preferably arranged around an axis parallel to the longitudinal axis of the support or cross support 3, said body 11 being provided, at its base 8, with at least one connecting member 13 to the cross member or support 3 and, at its top, means 14 for securing to the or a zone 7 for connecting the mattress support tray 6.

Dans l'exemple représenté, l'élément amortisseur comprend deux corps 11 entretoisés solidarisés chacun à une zone 7 de liaison d'un plateau 6 support. Chaque corps est formé de deux structures 12 tubulaires superposées organisées chacune autour d'un axe parallèle à l'axe longitudinal des traverses support. Chaque structure tubulaire affecte la forme d'un losange.In the example shown, the damping element comprises two braced bodies 11 each secured to a connection zone 7 of a support plate 6. Each body is formed of two superimposed tubular structures 12 each organized around an axis parallel to the longitudinal axis of the support rails. Each tubular structure has the shape of a diamond.

La structure 12 tubulaire du corps 11 d'élément 4 amortisseur solidarisée à la ou une zone 7 de liaison du plateau 6 support de matelas affecte la forme d'un losange à sommet aplati dans sa zone de solidarisation à la zone 7 de liaison.The tubular structure 12 of the body 11 of the damping element 4 secured to the or a connecting zone 7 of the mattress support plate 6 has the shape of a rhombus with a flattened crown in its zone of attachment to the zone 7 of connection.

Les côtés du losange jouxtant ledit sommet aplati sont aptes à former des butées de fin de course d'au moins une partie de la zone 7 de liaison, en l'occurrence des bras 9 de ladite zone en position extrême de déformation de ladite zone de liaison, à l'état sollicité de la face 61 active du plateau 6 par une charge d'appui tandis que le sommet aplati du losange forme une surface d'appui de la base 8 de raccordement de la zone 7 de liaison du plateau 6 support à l'élément 4 amortisseur. Ce sommet aplati du losange comporte un orifice traversant positionné en regard de l'orifice traversant de la base 8 de raccordement de la zone 7 de liaison du plateau 6 support. Un rivet est inséré dans le passage ménagé par l'alignement d'orifices.The sides of the rhombus adjacent to said flattened top are able to form end stops of at least a portion of the connecting zone 7, in this case arms 9 of said zone in the extreme position of deformation of said zone. connection, in the biased state of the active face 61 of the plate 6 by a bearing load while the flattened crown of the rhombus forms a bearing surface of the base 8 of the connecting zone 7 connecting the support plate 6 to the element 4 shock absorber. This flattened top of the diamond has a through hole positioned facing the through hole of the base 8 connecting the zone 7 of the support plate 6. A rivet is inserted into the passage formed by the alignment of orifices.

Les moyens 14 de solidarisation de l'élément amortisseur aux zones 7 de liaison du plateau 6 support de matelas sont donc des moyens de solidarisation par rivetage.The means 14 for securing the damping element to the zones 7 of connection of the mattress support plate 6 are thus securing means by riveting.

D'autres moyens 14 de solidarisation auraient pu être imaginés. Ainsi le sommet aplati du losange aurait pu être équipé d'un plot inséré à force dans l'orifice traversant de la base 8 de raccordement de la zone 7 de liaison du plateau support.Other means 14 of solidarity could have been imagined. Thus the flattened top of the diamond could have been equipped with a stud inserted forcibly into the through hole of the base 8 for connecting the zone 7 of connection of the support plate.

Les entretoises 15 entre corps de l'élément amortisseur confèrent ici à la zone entretoisée la forme d'un losange. Ces entretoises s'étendent ici entre les sommets de deux losanges disposés sensiblement à un même niveau, chaque losange appartenant à un corps de l'élément amortisseur. Une entretoise supplémentaire est disposée au niveau de la structure tubulaire la plus inférieure de la superposition de structures tubulaires de chaque corps et relie entre elles lesdites structures au niveau de leur organe 13 de liaison à une traverse support.The spacers 15 between the body of the damping element here confer the zone braced in the shape of a rhombus. These spacers extend here between the vertices of two lozenges arranged substantially at the same level, each rhombus belonging to a body of the damping element. An additional spacer is disposed at the level of the lowest tubular structure of the superposition of tubular structures of each body and interconnects said structures at their member 13 connecting to a cross support.

L'organe 13 de liaison de chaque corps 11 de l'élément 4 amortisseur à une traverse support affecte, quant à lui, la forme d'un anneau accolé par sa surface périphérique externe au pourtour périphérique du corps 11 de l'élément 4 amortisseur, la traverse 3 support étant enfilée dans ledit anneau.The connecting member 13 of each body 11 of the damping member 4 to a support cross member, for its part, has the shape of a ring joined by its outer peripheral surface to the periphery of the body 11 of the element 4 damper, the crosspiece 3 support being threaded into said ring.

Le dispositif comporte donc ici deux traverses 3 support parallèles. Ces traverses 3 support sont fixées à chacune de leurs extrémités à un longeron. La fixation peut s'opérer par vissage, emboîtement ou autre.The device therefore comprises here two parallel support rails 3. These support rails 3 are fixed at each of their ends to a spar. Fixing can be done by screwing, interlocking or other.

Une fois positionné entre deux longerons, un tel dispositif de suspension est apte à se déformer d'une manière conforme à celle représentée aux figures 3 à 6.Once positioned between two longitudinal members, such a suspension device is able to deform in a manner consistent with that shown in FIGS. Figures 3 to 6 .

La figure 3 illustre le dispositif de suspension au repos en l'absence de toute sollicitation.The figure 3 illustrates the suspension device at rest in the absence of any solicitation.

Généralement lorsqu'un matelas est posé sur la face 61 active du plateau 6, la force d'appui du matelas est insuffisante pour générer une déformation du dispositif de suspension.Generally when a mattress is placed on the active face 61 of the plate 6, the support force of the mattress is insufficient to generate a deformation of the suspension device.

Lorsqu'une personne vient s'asseoir ou se coucher en un emplacement du matelas reposant localement sur le dispositif de suspension, on observe une déformation progressive du dispositif avec, dans un premier temps, une déformation de la zone de liaison (figure 4) jusqu'à une position extrême de déformation (figure 5) dans laquelle les bras de la zone de liaison viennent en appui sur les côtés supérieurs d'un losange du corps d'élément amortisseur.When a person comes to sit or lie down at a location of the mattress resting locally on the suspension device, a progressive deformation of the device is observed with, initially, a deformation of the connecting zone ( figure 4 ) to an extreme position of deformation ( figure 5 ) in which the arms of the connection zone bear on the upper sides of a rhombus of the damping element body.

La déformation se poursuit ensuite par déformation des structures tubulaires du corps (figure 6). Selon le poids et la position de l'utilisateur sur le matelas, on observe ou non tous les stades de déformation décrits ci-dessus.The deformation is then continued by deformation of the tubular structures of the body ( figure 6 ). Depending on the weight and the position of the user on the mattress, we observe or not all stages of deformation described above.
