Description

La présente invention concerne le domaine des lits de relaxation, notamment ceux dans lesquels il est possible d'incliner une partie buste/tête et/ou une partie pieds.The present invention relates to the field of relaxation beds, in particular those in which it is possible to incline a bust / head portion and / or a foot portion.

La présente invention concerne plus particulièrement les plans de couchage comprenant un cadre de sommier de lit s'étendant selon une direction longitudinale et comportant une première portion de plan et une deuxième portion de plan, des moyens pour incliner la deuxième portion de plan par rapport à la première portion de plan selon un axe transversal au cadre de sommier.The present invention more particularly relates to coating planes comprising a bed frame frame extending in a longitudinal direction and having a first plan portion and a second plan portion, means for inclining the second plan portion relative to the first plan portion along an axis transverse to the bed frame.

De tels plans de couchage sont connus par ailleurs et sont généralement destinés à supporter des matelas dont l'épaisseur peut varier en fonction du confort recherché par l'utilisateur.Such sleeping plans are known elsewhere and are generally intended to support mattresses whose thickness may vary depending on the comfort sought by the user.

En position inclinée, les première et deuxième portions de plan forment un angle, tandis que le matelas est courbé, si bien que la surface externe du matelas, c'est-à-dire celle apte à être en contact avec le plan de couchage, ne peut pas épouser de façon naturelle la partie du plan de couchage formant la jonction entre les première et deuxième portions de plan.In inclined position, the first and second plane portions form an angle, while the mattress is curved, so that the outer surface of the mattress, that is to say that able to be in contact with the coating plane, can not marry in a natural way the part of the sleeping plane forming the junction between the first and second portions of plan.

Dès lors, en l'absence de l'utilisateur, on constate qu'en position inclinée, le matelas décolle du plan de couchage au niveau de la jonction entre les première et deuxième portions de plan, ce décollement étant d'autant plus significatif que la deuxième portion de plan est plus fortement inclinée par rapport à la première portion de plan.Therefore, in the absence of the user, it is noted that in inclined position, the mattress off the sleeping surface at the junction between the first and second plan portions, this detachment being all the more significant that the second plan portion is more strongly inclined relative to the first plan portion.

Par suite, lorsque l'utilisateur s'assied sur le matelas incliné, notamment à l'aplomb de la zone de décollement, le poids de l'utilisateur repousse le matelas contre le plan de couchage, si bien que l'utilisateur a la sensation désagréable de s'enfoncer dans le lit jusqu'au moment où le matelas vient en contact avec le plan de couchage.As a result, when the user sits on the inclined mat, in particular at the level of the separation zone, the weight of the user pushes the mattress against the sleeping surface, so that the user has the sensation unpleasant to sink into the bed until the mattress comes in contact with the sleeping area.

Le but de la présente invention est de donc fournir un plan de couchage présentant un confort amélioré.The object of the present invention is therefore to provide a sleeping surface with improved comfort.

Ce but est atteint par le fait qu'il comporte en outre une portion de plan intermédiaire disposée entre les première et deuxième portions de plan et des moyens pour incliner la portion de plan intermédiaire par rapport aux première et deuxième portions de plan de telle manière que lorsque la deuxième portion de plan est inclinée, l'angle d'inclinaison entre la portion de plan intermédiaire et la première portion de plan est inférieure à l'angle d'inclinaison entre les première et deuxième portions de plan, le plan de couchage comportant en outre des moyens pour déplacer en translation la deuxième portion de plan, la portion de plan intermédiaire étant fixée de manière pivotante à la deuxième portion de planThis object is achieved by the fact that it further comprises an intermediate plane portion disposed between the first and second plane portions and means for inclining the intermediate plane portion with respect to the first and second plane portions such that when the second plane portion is inclined, the angle of inclination between the intermediate plane portion and the first plane portion is less than the angle of inclination between the first and second plane portions, the coating plane further comprising means for translational movement of the second plane portion, the intermediate plane portion being pivotally attached to the second portion; plan

De manière préférentielle, la portion de plan intermédiaire supporte à tout moment le matelas, notamment lorsque celui est en position inclinée.Preferably, the intermediate plane portion supports the mattress at all times, especially when the one is in an inclined position.

En l'espèce, comme l'angle d'inclinaison entre la portion de plan intermédiaire et la première portion de plan est avantageusement inférieur à l'angle d'inclinaison entre les première et deuxième portions de plan, on comprend qu'on peut ainsi prévoir que l'inclinaison du plan intermédiaire soit telle que le plan intermédiaire est sensiblement tangent à la surface externe du matelas lorsque celui est incliné, par quoi le matelas en position inclinée demeure supporté par le plan de couchage même en l'absence de l'utilisateur.In the present case, since the angle of inclination between the intermediate plane portion and the first plane portion is advantageously less than the angle of inclination between the first and second plane portions, it will be understood that provide that the inclination of the intermediate plane is such that the intermediate plane is substantially tangential to the outer surface of the mattress when the inclined, whereby the mattress in inclined position remains supported by the sleeping plane even in the absence of the user.

Dès lors, le plan de couchage selon l'invention permet d'éviter que, lorsqu'il s'assied, l'utilisateur ne ressente un enfoncement du matelas lorsque ce dernier est incliné.Therefore, the sleeping surface according to the invention makes it possible to avoid that, when seated, the user feels a depression of the mattress when the latter is inclined.

De manière préférentielle mais non nécessairement, la deuxième portion de plan correspond à la portion du plan qui supporte le buste et éventuellement la tête de l'utilisateur, tandis que la première portion de plan est celle destinée à supporter le reste du corps de l'utilisateur.Preferably, but not necessarily, the second plane portion corresponds to the portion of the plane that supports the bust and possibly the head of the user, while the first portion of the plane is that intended to support the rest of the body of the body. user.

Lorsque l'on incline la deuxième portion de plan par rapport à la première portion de plan, le matelas subit une déformation en flexion de telle sorte que, vu selon sa direction longitudinale, il présente une fibre moyenne, dont la longueur est sensiblement égale à la longueur du matelas déplié et une fibre externe, proche du plan de couchage, dont la longueur est supérieure à celle de la fibre moyenne.When the second planar portion is inclined with respect to the first planar portion, the mattress undergoes flexural deformation such that, viewed along its longitudinal direction, it exhibits an average fiber, the length of which is substantially equal to the length of the unfolded mattress and an outer fiber, close to the coating plane, whose length is greater than that of the average fiber.

Comme la longueur de la fibre externe du matelas est plus grande que celle de la fibre moyenne, il en résulte que la longueur de la surface externe augmente d'autant plus que le matelas est incliné.As the length of the outer fiber of the mattress is greater than that of the average fiber, it follows that the length of the outer surface increases the more the mattress is inclined.

On comprend donc que l'extrémité du matelas qui est situé du côté de la tête de l'utilisateur a tendance à se déplacer vers l'extrémité du plan de couchage située du côté de la tête de l'utilisateur.It is therefore understood that the end of the mattress which is located on the side of the head of the user tends to move towards the end of the sleeping plane located on the side of the user's head.

Grâce à la présente invention, la deuxième portion de plan se déplace en translation lorsque la deuxième portion de plan est inclinée, de manière à accompagner le déplacement du matelas lors de l'inclinaison de celui-ci. Cela permet de garantir un soutien constant du matelas.Thanks to the present invention, the second plane portion moves in translation when the second plane portion is inclined, so as to accompany the movement of the mattress during the inclination thereof. This ensures a constant support of the mattress.

En outre, on comprend que la deuxième portion de plan ne peut que pivoter par rapport à la portion de plan intermédiaire. Il n'y a donc pas d'éloignement relatif entre la portion de plan intermédiaire et la deuxième portion de plan.In addition, it is understood that the second plane portion can only pivot relative to the intermediate plane portion. There is therefore no relative distance between the intermediate plane portion and the second plane portion.

Avantageusement, la portion de plan intermédiaire est fixée de manière pivotante à la première portion de plan.Advantageously, the intermediate plane portion is pivotally attached to the first plane portion.

Avantageusement, les moyens pour incliner la deuxième portion de plan par rapport à la première portion de plan comportent au moins un bras d'appui monté pivotant autour d'un axe transversal au sommier.Advantageously, the means for inclining the second plane portion relative to the first plane portion comprise at least one support arm pivotally mounted about an axis transverse to the bed.

De manière préférentielle, le bras d'appui s'étend selon la direction longitudinale du plan de couchage, vers l'extrémité du plan de couchage située du côté de la tête de l'utilisateur.Preferably, the support arm extends in the longitudinal direction of the coating plane, towards the end of the coating plane located on the side of the head of the user.

Préférentiellement, le cadre de sommier comporte au moins un long pan s'étendant selon la direction longitudinale du sommier tandis que le bras d'appui est avantageusement fixé de manière pivotante à ce long pan.Preferably, the bed frame has at least one long pan extending in the longitudinal direction of the bed base while the support arm is advantageously pivotally attached to this long pan.

On comprend donc que le bras d'appui peut être incliné par rapport au long pan.It is therefore understood that the support arm can be inclined relative to the long pan.

Avantageusement, les moyens pour incliner la portion de plan intermédiaire comportent un moyen de guidage apte à coopérer avec ledit au moins un bras d'appui, de telle sorte que l'inclinaison du bras d'appui entraîne l'inclinaison de la portion de plan intermédiaire.Advantageously, the means for inclining the intermediate plane portion comprise a guiding means adapted to cooperate with said at least one support arm, so that the inclination of the support arm causes the inclination of the plane portion. intermediate.

Avantageusement, le moyen de guidage comporte au moins une roue fixée à la portion de plan intermédiaire tout en étant apte à se déplacer le long du bras d'appui.Advantageously, the guide means comprises at least one wheel fixed to the intermediate plane portion while being able to move along the support arm.

De manière préférentielle, la roue est destinée à rouler le long du bras d'appui.Preferably, the wheel is intended to roll along the support arm.

On comprend donc que lorsque l'on incline le bras d'appui, la roue se déplace en roulant vers l'extrémité du bras d'appui qui est située du côté de la tête de l'utilisateur.It is therefore understood that when the support arm is inclined, the wheel moves while rolling toward the end of the support arm which is located on the side of the user's head.

De manière préférentielle, les moyens pour incliner la deuxième portion de plan par rapport à la première portion de plan comportent deux bras d'appui disposés de part et d'autre de la largeur du cadre de sommier.Preferably, the means for inclining the second plane portion relative to the first plane portion comprise two support arms arranged on either side of the width of the bed frame.

Le moyen de guidage comporte préférentiellement deux roues aptes à se déplacer le long des bras d'appui, afin d'améliorer la stabilité de la deuxième portion de plan lors de son inclinaison.The guide means preferably comprises two wheels able to move along the support arms, in order to improve the stability of the second plane portion during its inclination.

Avantageusement, les moyens pour incliner la deuxième portion de plan comportent un dispositif de guidage apte à guider le déplacement de la deuxième portion de plan par rapport audit au moins un bras d'appui, lorsque la deuxième portion de plan est inclinée.Advantageously, the means for inclining the second plane portion comprise a guiding device adapted to guide the displacement of the second plane portion relative to said at least one support arm, when the second plane portion is inclined.

De préférence, la première portion de plan est disposée sensiblement dans un plan défini par le cadre de sommier.Preferably, the first plane portion is disposed substantially in a plane defined by the bed frame.

Avantageusement, la portion de plan intermédiaire comporte un élément de soutien apte à supporter un matelas.Advantageously, the intermediate plane portion comprises a support member adapted to support a mattress.

Cet élément de soutien peut comprendre par exemple mais non nécessairement une latte de suspension.This support element may comprise for example but not necessarily a suspension slat.

Par ailleurs, on peut prévoir d'autres dispositifs de suspension disposés sur les première et/ou deuxième portion(s) de plan, telles des lattes fixées à leurs extrémités à des embouts à lattes.Furthermore, other suspension devices may be provided on the first and / or second portion (s) plane, such slats attached at their ends to slatted ends.

Dans les plans de couchage déjà connus, certains comportent de tels dispositifs de suspension munis de lattes disposés sur les première et deuxième portions de plan. Pour ceux-ci, lorsque la deuxième portion de plan est inclinée, on constate que les dispositifs de suspension se rapprochent si bien que le matelas a tendance à être pincé entre les dispositifs de suspension des première et deuxième portions de plan, ce qui risque d'endommager le matelas.In the already known sleeping planes, some comprise such suspension devices provided with slats arranged on the first and second plan portions. For these, when the second portion of plane is inclined, it is found that the suspension devices are so close that the mattress tends to be pinched between the suspension devices of the first and second plan portions, which may 'damage the mattress.

Grâce à la présente invention, comme les première et deuxième portions de plan sont davantage écartées du fait de la présence de la portion de plan intermédiaire, on comprend que l'on évite substantiellement ce phénomène de pincement du matelas.With the present invention, as the first and second plan portions are further apart due to the presence of the intermediate plane portion, it is understood that this phenomenon of pinching of the mattress is substantially avoided.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux à la lecture de la description qui suit d'un mode de réalisation de l'invention donné à titre d'exemple non limitatif.Other features and advantages of the invention will appear better on reading the following description of an embodiment of the invention given by way of non-limiting example.

Sur la figure 1 , on a représenté un plan de couchage 10 selon l'invention qui comporte un cadre de sommier de lit 12 comprenant deux longs pans 28 s'étendant selon la direction longitudinale du plan de couchage 10. On the figure 1 , there is shown a coating plane 10 according to the invention which comprises a bed base frame 12 comprising two long panels 28 extending in the longitudinal direction of the coating plane 10.

Le plan de couchage 10 selon l'invention comprend une première portion de plan 14 et une deuxième portion de plan 16 destinées à supporter un matelas 32. The coating plane 10 according to the invention comprises a first plane portion 14 and a second plane portion 16 for supporting a mattress 32.

Sur l'exemple représenté à la figure 1 , la première portion de plan 14 correspond à une portion du plan de couchage 10 qui est destinée à supporter les jambes de l'utilisateur (non représenté ici), tandis que la deuxième portion 16 est quant à elle destinée à supporter le buste et la tête de l'utilisateur.In the example shown in figure 1 , the first plane portion 14 corresponds to a portion of the lying plane 10 which is intended to support the legs of the user (not shown here), while the second portion 16 is in turn intended to support the bust and the head of the user.

Comme on le voit sur la figure 2 , la deuxième portion de plan 16 est apte à être inclinée par rapport à la première portion de plan 14 grâce à des moyens 18, 20,22 pour incliner la deuxième portion de plan 16 par rapport à la première portion de plan 14 autour d'un axe transversal au cadre de sommier 12. As we see on the figure 2 , The second plane portion 16 is adapted to be inclined with respect to the first plane portion 14 with means 18, 20,22 for inclining the second plane portion 16 relative to the first plane portion 14 around a transverse axis to the bed frame 12.

Ces moyens 18, 20,22 comportent une paire de bras d'appui 20, qui s'étendent selon la direction longitudinale du cadre de sommier 12 vers l'extrémité du plan de couchage située du côté de la tête de l'utilisateur, chacun des bras d'appui étant fixé de manière pivotante à l'un des deux longs pans 28. These means 18, 20, 22 comprise a pair of support arms 20, which extend in the longitudinal direction of the bed frame 12 towards the end of the sleeping surface situated on the side of the user's head, each bearing arms being pivotally attached to one of the two long pieces 28.

Comme on le voit sur la figure 2 , ces moyens 18,20,22 comportent en outre des moyens moteur 18 permettant de faire pivoter les bras d'appui 20, ainsi qu'un dispositif de guidage 22 apte à guider le déplacement de la deuxième portion de plan 16 par rapport aux bras d'appui 20. Ledit dispositif de guidage 22 comporte une paire de pièces triangulaires 22 qui sont fixées à chacune des extrémités transversales de la deuxième portion de plan 16, ainsi que des roulettes 22' destinées à coopérer avec les bras d'appui 20. As we see on the figure 2 These 18,20,22 means further comprises motor means 18 for pivoting the support arms 20, and a guide device 22 adapted to guide the displacement of the second plane portion 16 relative to the arms 20. Said guide device 22 comprises a pair of triangular pieces 22 which are fixed at each of the transverse ends of the second plane portion 16, as well as rollers 22 ' intended to cooperate with the support arms 20.

À l'aide des figures 1 et 2 , on comprend que, partant de la position non inclinée de la figure 1 , lorsque l'on incline les bras d'appui 20 d'un angle β par rapport à un plan défini par le cadre de sommier 12 (en l'espèce, sensiblement horizontal), les bras d'appui 20 agissent sur les pièces triangulaires 22 en les poussant par le biais des roulettes 22', ce qui entraîne l'inclinaison de la deuxième portion de plan 16 selon un angle α. En outre, on prévoit qu'en position inclinée, l'angle d'inclinaison α de la deuxième portion de plan 16 est égal ou légèrement supérieure à l'angle d'inclinaison β des bras d'appui 20. Using the help of Figures 1 and 2 , we understand that, starting from the non-inclined position of the figure 1 , When the inclined support arm 20 by an angle β relative to a plane defined by the bed frame 12 (in this case, substantially horizontal), the support arms 20 act on the triangular pieces 22 by pushing them through the rollers 22 ', resulting in the inclination of the second plane portion 16 at an angle α. In addition, it is expected that in an inclined position, the angle of inclination α of the second plane portion 16 is equal to or slightly greater than the angle of inclination β of the support arms 20.

Comme on le constate à l'aide des figures 3 et 4 , le plan de couchage 10 selon l'invention comporte en outre une portion de plan intermédiaire 24 s'étendant transversalement par rapport au plan de couchage, cette portion de plan intermédiaire 24 étant disposée entre la première portion de plan 14 et la deuxième portion de plan 16. As can be seen from the Figures 3 and 4 , the coating plane 10 according to the invention further comprises an intermediate plane portion 24 extending transversely to the coating plane, this intermediate plane portion 24 being disposed between the first plane portion 14 and the second portion of the plane. plan 16.

De manière avantageuse, la portion de plan intermédiaire 24 est fixée en rotation d'une part à la première portion de plan 14 par le biais d'un axe de pivotement B transversal au cadre de sommier 12, et d'autre part à la deuxième portion de plan 16 par le biais d'un axe de pivotement C également transversal au cadre de sommier 12. De manière préférentielle, l'axe de pivotement des bras d'appui 20 et l'axe de pivotement C entre la deuxième portion de plan 16 et la portion de plan intermédiaire 24 sont disposés dans un même plan qui est sensiblement orthogonal au plan défini par le cadre du sommier 12, ou légèrement inclinée par rapport à celui, comme cela représenté sur la figure 3 . Advantageously, the portion of intermediate plane 24 is fixed in rotation on the one hand to the first plane portion 14 by means of a pivot axis B transversal to the frame of bed base 12, and secondly to the second portion of plane 16 through a pivot axis C also transverse to the bed frame 12. Preferably, the pivot axis of the support arm 20 and the pivot axis C between the second portion of plane 16 and the intermediate plane portion 24 are arranged in the same plane which is substantially orthogonal to the plane defined by the frame of the bed base 12, or slightly inclined with respect to that, as represented on the figure 3 .

Lorsque le plan de couchage n'est pas incliné, comme cela a représenté sur la figure 3 , on constate que la portion de plan intermédiaire 24 supporte une zone du matelas 32. Autrement dit, les première et deuxième portions de plan ainsi que la portion de plan intermédiaire 24 s'étendent sensiblement dans un même plan.When the sleeping plane is not inclined, as has been shown on the figure 3 , It is observed that the intermediate plane portion 24 supports an area of the mattress 32. In other words, first and second plan portions and the intermediate plane portion 24 extend substantially in the same plane.

On constate également que les axes de pivotement B et C de la portion de plan intermédiaire 24 sont contenus, dans la position non inclinée de la figure 3 , dans un plan situé à distance d'un plan longitudinal au cadre de sommier 12 et contenant l'axe de pivotement des bras d'appui 20. It can also be seen that the pivot axes B and C of the intermediate plane portion 24 are contained in the non-inclined position of the figure 3 , In a plane spaced from a longitudinal plane to the platen frame 12 and containing the pivot axis of the support arm 20.

Le plan de couchage 10 selon l'invention comporte en outre des moyens 26,20 pour incliner la portion de plan intermédiaire 24 par rapport aux première et deuxième portions de plan. L'angle d'inclinaison entre la portion de plan intermédiaire 24 et la première portion de plan porte la référence γ sur la figure 4 . The coating plane 10 according to the invention further comprises means 26,20 for inclining the intermediate plane portion 24 with respect to the first and second plane portions. The angle of inclination between the intermediate plane portion 24 and the first plane portion bears the reference γ on the figure 4 .

Les moyens pour incliner la portion de plan intermédiaire 24 comportent un moyen de guidage 26 apte à coopérer avec les bras d'appui 20, de telle sorte que l'inclinaison des bras d'appui 20 entraîne l'inclinaison de la portion de plan intermédiaire 24.
Le moyen de guidage 26 comporte de manière préférentielle deux roues 26 ayant des axes de rotation transversaux au cadre de sommier 12, chacune des roues 26 étant fixée en rotation à l'extrémité d'une tige 29 de la portion de plan intermédiaire 24 s'étendant orthogonalement par rapport à une direction longitudinale de la portion de plan intermédiaire 24, cette direction étant sensiblement transversale au cadre de sommier 12. The means for inclining the intermediate plane portion 24 comprise a guiding means 26 adapted to cooperate with the support arms 20, so that the inclination of the support arms 20 causes the inclination of the intermediate plane portion. 24.
The guiding means 26 preferably comprises two wheels 26 having axes of rotation transverse to the bed frame 12, each of the wheels 26 being fixed in rotation at the end of a rod 29 of the intermediate plane portion 24 s'. extending orthogonally with respect to a longitudinal direction of the intermediate plane portion 24, this direction being substantially transverse to the bed frame 12.

Comme on le constate sur la figure 3 , lorsque la deuxième portion de plan n'est pas inclinée, les axes de rotation des roues 26 sont préférentiellement disposés entre l'axe de pivotement des bras d'appui 20 et l'extrémité du plan de couchage 10 situé du côté de la tête de l'utilisateur.As we see on the figure 3 When the second plane portion is not inclined, the rotational axes of wheels 26 are preferably arranged between the pivot axis of the support arm 20 and the end of the lying surface 10 located on the side of the head of the user.

Partant de la position représentée sur la figure 3 , dans laquelle les bras d'appui 20 sont en contact avec les roulettes 22', on comprend que lorsque l'on incline les bras d'appui 20, on incline tout d'abord la deuxième portion de plan jusqu'à ce que les bras d'appui 20 viennent en contact avec les roues 26. Starting from the position represented on the figure 3 , in which the support arms 20 are in contact with the rollers 22 ', it is understood that when the support arms 20 are inclined, the first plane portion is first inclined until the support arms 20 come into contact with the wheels 26.

Dans cette position, la deuxième portion de plan 16 est inclinée par rapport à portion de plan intermédiaire 24, tandis que cette dernière n'est pas inclinée par rapport à la première portion de plan 14, si bien que l'angle inclinaison γ entre la portion de plan intermédiaire et la première portion de plan (sensiblement nul en l'espèce) est bien inférieure à l'angle inclinaison α entre les première et deuxième portions de plan.In this position, the second plane portion 16 is inclined relative to the intermediate plane portion 24, while the latter is not inclined with respect to the first plane portion 14, so that the inclination angle γ between the intermediate plane portion and the first plane portion (substantially zero in this case) is much lower than the inclination angle α between the first and second plane portions.

Comme cela est bien visible sur la figure 4 , lorsque l'on incline encore les bras d'appui 20, ceux-ci agissent sur les roues 26 entraînant ainsi la portion de plan intermédiaire 24 par rapport à la première portion de plan 14. As is clearly visible on the figure 4 , When still tilts the supporting arm 20, the latter acting on the wheels 26 thereby causing the intermediate plane portion 24 relative to the first portion of plane 14.

Par ailleurs, du fait de la position relative de l'axe de pivotement A des bras d'appui 20 par rapport à l'axe de pivotement B de la portion de plan intermédiaire 24 par rapport à la première portion de plan 14, les roues 26 se déplacent en roulant le long des bras d'appui 20, lorsque les bras d'appui 20 sont inclinés.Moreover, because of the relative position of the pivot axis A of the support arms 20 with respect to the pivot axis B of the intermediate plane portion 24 with respect to the first plane portion 14, the wheels 26 move by rolling along the support arms 20, when the support arms 20 are inclined.

En outre, notamment du fait que l'axe de pivotement A des bras d'appui 20 est situé entre l'axe de pivotement B de la portion de plan intermédiaire 24 par rapport à la première portion de plan 14, et l'extrémité du plan de couchage située du côté de la tête de l'utilisateur, on comprend que l'angle inclinaison β des bras d'appui 20 est supérieur à l'angle inclinaison γ de la portion de plan intermédiaire 24 par rapport à la première portion de plan 14 et que par conséquent, conformément à l'invention, l'angle d'inclinaison γ de la portion de plan intermédiaire 24 par rapport à la première portion de plan 14 est inférieur à l'angle d'inclinaison α de la deuxième portion de plan 16 par rapport à la première portion de plan 14. In addition, in particular because the pivot axis A of the support arms 20 is situated between the pivot axis B of the intermediate plane portion 24 with respect to the first plane portion 14, and the end of the lying plane on the side of the user's head, it is understood that the inclination angle β of the support arms 20 is greater than the inclination angle γ of the intermediate plane portion 24 with respect to the first portion of the plan 14 and that therefore, according to the invention, the inclination angle γ of the intermediate plane portion 24 with respect to the first plane portion 14 is less than the angle of inclination α of the second portion of plane 16 with respect to the first plane portion 14.

En dimensionnant de manière appropriée le diamètre des roues 26 et/ou la longueur des tiges 29, ainsi que la position des axes de pivotement B et C, il est possible d'ajuster le rapport entre l'angle d'inclinaison γ de la portion de plan intermédiaire 24 et l'angle d'inclinaison β des bras d'appui 20. De même, il est possible d'ajuster le rapport entre l'angle d'inclinaison β des bras d'appui et l'angle d'inclinaison α de la deuxième portion de plan 16 en réglant la position des roulettes 22' par rapport aux bras d'appui 20, de telle manière que la portion de plan intermédiaire supporte le matelas 32 tout en étant tangente à la surface externe 32' dudit matelas 32. By suitably dimensioning the diameter of the wheels 26 and / or the length of the rods 29, as well as the position of the pivot axes B and C, it is possible to adjust the ratio between the angle of inclination γ of the portion intermediate plane 24 and the angle of inclination β of the support arms 20. Similarly, it is possible to adjust the ratio between the angle of inclination β of the support arms and the angle of inclination α of the second plane portion 16 by adjusting the position of the rollers 22 ' relative to the support arm 20, so that the intermediate plane portion supports the mattress 32 while being tangential to the outer surface 32 ' of said mattress 32.

De manière préférentielle, la portion de plan intermédiaire 24 est tangente au sommet de l'extrados constitué par la surface externe 32' du matelas 32. Preferably, the portion of intermediate plane 24 is tangent to the top of the extrados constituted by the outer surface 32 ' of the mattress 32.

Par ailleurs, lorsque l'on incline les bras d'appui 20, on comprend à l'aide de la figure 4 que l'inclinaison de la portion de plan intermédiaire 24 entraîne le déplacement de la deuxième portion de plan 16 le long des bras d'appui 20, ce déplacement étant guidé par les roulettes 22' du dispositif de guidage 22 déjà mentionné ci-dessus.Moreover, when the support arms 20 are inclined , it is possible to understand by means of the figure 4 that the inclination of the portion of intermediate plane 24 causes the displacement of the second portion of plane 16 along the support arms 20, this movement being guided by the rollers 22 ' of the guide device 22 already mentioned above.

Sur la figure 5 , on a représenté un mode de réalisation de la portion de plan intermédiaire 24. On the figure 5 There is shown one embodiment of the intermediate planar portion 24.

De manière avantageuse, la portion de plan intermédiaire comporte en outre un élément de soutien 30 apte à supporter le matelas 32, ainsi qu'un corps 34. Advantageously, the intermediate plane portion further comprises a support element 30 able to support the mattress 32, as well as a body 34.

Cet élément de soutien 30 comporte de préférence un dispositif de suspension comprenant une latte de suspension 36 unique fixée à chacune de ses extrémités au corps 34 par des embouts de lattes 38. This support element 30 preferably comprises a suspension device comprising a single suspension slat 36 fixed at each of its ends to the body 34 by slat ends 38.

Selon une variante avantageuse, on remplace la latte simple par une paire de lattes de suspension parallèles entre elles.According to an advantageous variant, the simple batten is replaced by a pair of suspension slats parallel to each other.

Selon une autre variante avantageuse, le dispositif de suspension comprend une triade de lattes de suspension comportant deux lattes supérieures, une latte inférieure et un curseur monté coulissant sur la latte inférieure et qui soit apte à entrer en contact avec les lattes supérieures lorsque la pression appliquée sur le dispositif de suspension est supérieure à une pression prédéterminée, le curseur étant déplaçable afin de régler la raideur du dispositif de suspension.According to another advantageous variant, the suspension device comprises a triad of suspension slats comprising two upper slats, a lower slat and a slider slidably mounted on the lower slat and which is adapted to come into contact with the upper slats when the applied pressure on the suspension device is greater than a predetermined pressure, the slider being movable to adjust the stiffness of the suspension device.

Le corps 34 comprend quant à lui une barre transversale 40 à laquelle sont fixées orthogonalement les deux tiges 29, et aux extrémités de laquelle sont disposées des éléments 42 pour fixer les embouts de lattes 38. Les roues 26 sont pour leur part montées pivotantes aux extrémités des tiges 29. The body 34 comprises meanwhile a transverse bar 40 to which are fixed orthogonally the two rods 29, and at the ends of which are arranged elements 42 for fixing the ends of slats 38. The wheels 26 are for their part pivotally mounted at the ends stems 29.
