Les extrémités des éléments gonflables cylindriques sont en biseaux et prennent appui sur des flancs inclinés opposés du logement, tandis que les deux autres flancs opposés du logement sont droits.The patent WO 03/024380 discloses a cushion member defining a housing in which is inserted a plurality of cylindrical inflatable elements arranged parallel to each other, free and independent of each other. The ends of the cylindrical inflatable elements are beveled and supported on opposite inclined flanks of the housing, while the other two opposite flanks of the housing are straight.

La présente invention a notamment pour but de proposer un dispositif de support dans lequel les risques de déformation et de désolidarisation des éléments le constituant sont réduits.The present invention is intended to provide a support device in which the risk of deformation and uncoupling of the constituent elements are reduced.

Selon un mode d'exécution, il est proposé un dispositif de support pour supporter un corps ou une partie d'un corps, en particulier un corps humain, qui comprend un élément de support en une matière déformable comprenant une assise et une paroi latérale périphérique en saillie d'un côté de ce plateau d'assise, de façon à délimiter un logement présentant un fond et une face latérale périphérique, et un élément pneumatique comprenant une embase et une pluralité de cellules gonflables en saillie d'un côté de l'embase et situées les unes à côté des autres, selon une matrice de lignes et de colonnes, les cellules gonflables étant engagées dans le logement et s'étendant entre le fond dudit logement et l'embase de l'élément pneumatique.According to one embodiment, there is provided a support device for supporting a body or part of a body, in particular a human body, which comprises a support member of a deformable material comprising a seat and a peripheral side wall protruding from one side of this seat plate, so as to define a housing having a bottom and a peripheral side face, and a pneumatic element comprising a base and a plurality of inflatable cells projecting from one side of the base and located next to each other, according to a matrix of rows and columns, the inflatable cells being engaged in the housing and extending between the bottom of said housing and the base of the pneumatic element.

La paroi latérale périphérique de l'élément de support comprend au moins un bourrelet de retenue en saillie vers l'intérieur et situé à distance du fond du logement, de telle sorte que la face latérale périphérique du logement présente au moins une portion en contre-dépouille, au moins certaines des cellules gonflables adjacentes audit bourrelet de retenue étant aptes, lorsqu'elles sont gonflées, à s'engager latéralement entre ce bourrelet de retenue et le fond du logement et retenir l'élément pneumatique le long de la périphérie ou du pourtour de ce logement.The peripheral side wall of the support member comprises at least one inwardly projecting retaining flange located at distance from the bottom of the housing, such that the peripheral lateral face of the housing has at least one undercut portion, at least some of the inflatable cells adjacent to said retaining bead being adapted, when inflated, to engage laterally between the retaining bead and the bottom of the housing and retain the pneumatic element along the periphery or around this housing.

L'embase de l'élément pneumatique présente un bord s'étendant sur une face d'extrémité de la paroi latérale périphérique de l'élément de support.The base of the pneumatic element has an edge extending on an end face of the peripheral side wall of the support member.

Ledit bourrelet de retenue peut comprendre des portions locales s'étendant respectivement sur une partie de la longueur de la face latérale périphérique dudit logement.Said retaining bead may comprise local portions extending respectively over a portion of the length of the peripheral lateral face of said housing.

Ledit bourrelet de retenue peut s'étendre sur toute la longueur de la face latérale périphérique dudit logement.Said retaining bead may extend over the entire length of the peripheral lateral face of said housing.

L'élément pneumatique peut comprendre au moins un conduit relié à au moins une cellule gonflable et traversant la paroi latérale périphérique de l'élément de support.The pneumatic element may comprise at least one duct connected to at least one inflatable cell and passing through the peripheral lateral wall of the support element.

Une plaque inférieure de support en une matière déformable, peut être prévue pour recouvrir l'embase de l'élément pneumatique et la face d'extrémité de la paroi périphérique de l'élément de support.A lower support plate made of a deformable material may be provided to cover the base of the pneumatic element and the end face of the peripheral wall of the support element.

Le dispositif peut en outre comprendre une housse extérieure.The device may further comprise an outer cover.

Un dispositif de support va maintenant être décrit à titre d'exemple non limitatif, illustré par le dessin annexé sur lequel :

  • la figure 1 représente une coupe transversale d'un dispositif de support comprenant un élément pneumatique dans un état dégonflé ;
  • la figure 2 représente une coupe transversale du dispositif de support de la figure 1, l'élément pneumatique étant dans un état gonflé ; et
  • la figure 3 représente une coupe transversale locale agrandie de l'élément pneumatique.
A support device will now be described by way of nonlimiting example, illustrated by the appended drawing in which:
  • the figure 1 represents a cross-section of a support device comprising a pneumatic element in a deflated state;
  • the figure 2 represents a cross section of the support device of the figure 1 the pneumatic element being in an inflated state; and
  • the figure 3 represents an enlarged local cross-section of the pneumatic element.

Comme illustré sur les figures 1 et 2, un dispositif de support 1, pouvant constituer par exemple un coussin pour s'asseoir, de forme générale parallélépipédique, comprend un élément de support 2 en une matière déformable, par exemple une mousse synthétique moulée telle qu'une mousse polyuréthane, qui comprend une assise horizontale 3, en forme de plateau, et une paroi périphérique 4 en saillie vers le bas depuis la périphérie de l'assise 3, de telle sorte que cet élément de support 2 délimite un logement en creux 5 ouvert vers le bas. Ce logement 5 présente un fond 6 constitué par une face inférieure de l'assise 3 et une face latérale ou périphérique 7 constituée par le flanc intérieur de la paroi périphérique 4.As illustrated on figures 1 and 2 a support device 1, which may for example constitute a seating cushion of generally parallelepipedal shape, comprises a support element 2 made of a deformable material, for example a molded synthetic foam such as a polyurethane foam, which comprises a horizontal seat 3, shaped tray, and a peripheral wall 4 projecting downwardly from the periphery of the seat 3, so that the support member 2 defines a hollow recess 5 open downwards. This housing 5 has a bottom 6 constituted by a lower face of the seat 3 and a lateral or peripheral face 7 constituted by the inner side of the peripheral wall 4.

La face supérieure de l'assise 3 de l'élément de support 2 peut être plate ou non et présenter une topographie souhaitée. Le fond 6 du logement 5 peut être plat. La face extérieure périphérique de la paroi périphérique 4 peut s'étendre perpendiculairement à la face supérieure de l'assise 3.The upper face of the seat 3 of the support element 2 may be flat or not and have a desired topography. The bottom 6 of the housing 5 can be flat. The outer peripheral face of the peripheral wall 4 can extend perpendicularly to the upper face of the seat 3.

La paroi périphérique 4 comprend un bourrelet périphérique de retenue 8 en saillie vers l'intérieur du logement 5 et situé à distance du fond 6, de telle sorte que la face latérale ou périphérique 7 du logement 5 présente une portion périphérique 7a en contre-dépouille, s'étendant entre le bourrelet périphérique de retenue 8 et le fond 6 du logement 5 et de section plus grande que la section intérieure du bourrelet périphérique 8.The peripheral wall 4 comprises a peripheral retaining bead 8 projecting towards the inside of the housing 5 and located at a distance from the bottom 6, so that the lateral or peripheral face 7 of the housing 5 has a peripheral portion 7a undercut. extending between the peripheral retaining bead 8 and the bottom 6 of the housing 5 and of larger section than the inner section of the peripheral bead 8.

Le dispositif de support 1 comprend en outre un élément pneumatique 9 qui comprend une embase 10 substantiellement plate et relativement rigide, qui est placée parallèlement au fond du logement 5 et dont le bord périphérique 10a est en appui sur une face inférieure d'extrémité 4a de la paroi périphérique 4, parallèle au fond 6 du logement 5, et une pluralité de cellules gonflables 11 en saillie vers le haut d'un côté de l'embase 10 et situées les unes à côté des autres, de telle sorte que ces cellules gonflables 11 sont engagées dans le logement 5 et s'étendent entre l'embase 10 et le fond 6 du logement 5.The support device 1 further comprises a pneumatic element 9 which comprises a base 10 substantially flat and relatively rigid, which is placed parallel to the bottom of the housing 5 and whose peripheral edge 10a is supported on a lower end face 4a of the peripheral wall 4, parallel to the bottom 6 of the housing 5, and a plurality of inflatable cells 11 projecting upwardly from one side of the base 10 and located next to each other, so that these inflatable cells 11 are engaged in the housing 5 and extend between the base 10 and the bottom 6 of the housing 5.

Les cellules gonflables 11 sont reliées entre elles par des canaux de liaison 12 de faibles sections, intégrés à l'embase 10, tandis que l'une des cellules gonflables périphériques 11a est reliée à un conduit 13 qui traverse la paroi périphérique 4 de l'élément de support 2 et qui est muni par exemple d'une valve extérieure d'extrémité 14 sur laquelle peut être branché un appareil de gonflage/dégonflage (non représenté).The inflatable cells 11 are interconnected by connection channels 12 of small sections, integrated into the base 10, while one of the inflatable peripheral cells 11a is connected to a conduit 13 which passes through the peripheral wall 4 of the support member 2 and which is provided for example with an outer end valve 14 on which can be connected an inflation / deflation device (not shown).

Les cellules gonflables 11 sont disposées selon une matrice de lignes et de colonnes, par exemple perpendiculaires. Les cellules gonflables 11 peuvent être disposées en quinconce.The inflatable cells 11 are arranged in a matrix of rows and columns, for example perpendicular. The inflatable cells 11 may be arranged in staggered rows.

Comme illustré sur la figure 3, l'embase 10 de l'élément pneumatique 9 peut comprendre une première feuille plate 15 et une feuille 16 présentant des zones accolées à la feuille 15 et, en ces zones, des déformations en saillie délimitant les cellules gonflables 11 et les canaux de liaison 12.As illustrated on the figure 3 , the base 10 of the pneumatic element 9 may comprise a first flat sheet 15 and a sheet 16 having areas contiguous to the sheet 15 and, in these areas, projecting deformations delimiting the inflatable cells 11 and the connecting channels. 12.

Comme illustré sur les figures 1 et 3, lorsque l'élément pneumatique 9 est dégonflé, les cellules gonflages 11 présentent un volume réduit. Dans cet état dégonflé, les cellules gonflages 11 peuvent être de section circulaire ou polygonale, par exemple de section hexagonale, leurs pieds adjacents à l'embase 10 étant distants les uns des autres.As illustrated on figures 1 and 3 when the pneumatic element 9 is deflated, the inflation cells 11 have a reduced volume. In this deflated state, the inflation cells 11 may be of circular or polygonal section, for example of hexagonal section, their feet adjacent to the base 10 being spaced apart from each other.

A l'état dégonflé, l'élément pneumatique 9 peut être aisément mis en place dans le logement 5 de l'élément de support 2 en faisant passer sans difficulté les cellules gonflables 11 au travers de la section intérieure du bourrelet 8.In the deflated state, the pneumatic element 9 can be easily placed in the housing 5 of the support element 2 by easily passing the inflatable cells 11 through the inner section of the bead 8.

Comme illustré sur la figure 2, lorsque l'on gonfle l'élément pneumatique 9, les cellules gonflages 11 se gonflent et viennent latéralement en appui les unes contre les autres, selon des génératrices perpendiculaires à l'embase 10, et contre le fond 6 du logement 5,As illustrated on the figure 2 when the pneumatic element 9 is inflated, the inflation cells 11 swell and come laterally against one another, along generatrices perpendicular to the base 10, and against the bottom 6 of the housing 5,

En outre, les cellules gonflages périphériques 11a de l'élément pneumatique 9, adjacentes au bourrelet de retenue 8, s'engagent latéralement dans l'évidement périphérique aménagé entre le bourrelet intérieur de retenue 8 et le fond 6 du logement 5 et peuvent venir en appui contre la portion en contre-dépouille 7a de la paroi latérale périphérique 7 du logement 5. Ainsi, la périphérie de l'élément pneumatique 9 est retenue le long de la périphérie du logement 5.In addition, the peripheral inflation cells 11a of the pneumatic element 9, adjacent to the retaining bead 8, engage laterally in the peripheral recess arranged between the inner retaining bead 8 and the bottom 6 of the housing 5 and may come into pressing against the undercut portion 7a of the side wall device 7 of the housing 5. Thus, the periphery of the pneumatic element 9 is retained along the periphery of the housing 5.

L'élément pneumatique 9, gonflé, occupe tout ou une grande partie du volume du logement 5 de l'élément de support 2, en fonction de la pression du gaz introduit, et forme un support pneumatique cohérent du fait que les cellules gonflées sont en appui les unes contre les autres et que les cellules gonflées périphériques sont en appui contre la portion en contre-dépouille 7a.The pneumatic element 9, inflated, occupies all or a large part of the volume of the housing 5 of the support element 2, as a function of the pressure of the introduced gas, and forms a coherent pneumatic support because the inflated cells are in against each other and that the inflated peripheral cells are in abutment against the undercut portion 7a.

Par rapport à des flancs droits, le bourrelet intérieur périphérique de retenue 8 constitue, le long de la périphérie du logement 5, un obstacle contre l'extraction des cellules gonflables périphériques 11a de l'élément pneumatique 9 à l'état gonflé et en conséquence de l'ensemble de l'élément pneumatique 9.With respect to straight flanks, the peripheral retaining bead 8 constitutes, along the periphery of the housing 5, an obstacle against the extraction of the inflatable peripheral cells 11a from the pneumatic element 9 in the inflated state and consequently of the entire pneumatic element 9.

Ainsi, grâce à l'existence du bourrelet intérieur périphérique de retenue 8, l'élément pneumatique gonflable 9, à l'état gonflé, est retenu contre son extraction du logement 5 de l'élément de support 2.Thus, thanks to the existence of the peripheral retaining bead 8, the inflatable pneumatic element 9, in the inflated state, is retained against its extraction from the housing 5 of the support element 2.

Optionnellement, le dispositif de support 1 peut comprendre une plaque inférieure de support 17 en une matière déformable, par exemple une mousse synthétique telle qu'une mousse polyuréthane, qui recouvre l'embase 10 de l'élément pneumatique 9 et la face inférieure 4a de la paroi périphérique 4 de l'élément de support 2, en prenant entre elles le bord périphérique 10a de l'embase 10. Selon une variante de réalisation, le bord périphérique 10a de l'embase 10 et/ou la plaque inférieure 17 peuvent être collés sur la face inférieure 4a de la paroi périphérique 4 de l'élément de support 2.Optionally, the support device 1 may comprise a lower support plate 17 made of a deformable material, for example a synthetic foam such as a polyurethane foam, which covers the base 10 of the pneumatic element 9 and the lower face 4a of the peripheral wall 4 of the support member 2, taking between them the peripheral edge 10a of the base 10. According to an alternative embodiment, the peripheral edge 10a of the base 10 and / or the lower plate 17 may be glued on the lower face 4a of the peripheral wall 4 of the support element 2.

Le dispositif de support 1 peut en outre comprendre une housse extérieure 18 en deux parties assemblées par une fermeture rapide périphérique 19, également traversée par le conduit 13. Cette housse peut être une toile éventuellement étanche.The support device 1 may further comprise an outer cover 18 in two parts assembled by a peripheral quick closure 19, also traversed by the conduit 13.
