Abstract

The seat, designed to adapt to the shape of the user's body, has a base (2) and side walls (3) made from a rigid, semi-rigid and/or impermeable material, and a top cover (5) made at least partly from an elastic and permeable material. The material used for the base and/or side walls is supple, impermeable and non-stretch, joined together and to the top cover e.g. by seams to make a pouch containing the non-compressible material, which fills its entire volume. In a variant the seat can be contained in an outer ring of a rigid material, rubber or synthetic foam, or inflatable.

Description

La présente invention a pour objet un siège, et plus spécialement un siège de salon comportant une enveloppe à l'intérieur de laquelle sont disposés des éléments de remplissage non compressibles, tels que des billes de polystyrène.The subject of the present invention is a seat, and more specially a salon seat with an envelope inside which are arranged non-compressible filling elements, such as polystyrene beads.

Il existe des sièges de ce type, dans lesquels l'enveloppe qui est, par exemple, réalisée en un matériau textile ou en une matière synthétique étanche, possède un volume intérieur supérieur au volume des billes constitutives des éléments de remplissage. Il est ainsi possible de déplacer les billes à l'intérieur de la poche, pour permettre différentes conformations du siège, et notamment pour adapter le siège à la forme du corps de l'utilisateur, en position assise. Toutefois, les sièges de ce type sont d'une esthétique peu agréable, dans la mesure où il existe un surplus d'enveloppe pour permettre le déplacement des billes de polystyrène, et le siège demeurant, lorsque l'utilisateur le quitte, dans la position dans laquelle il était avant que l'utilisateur ne se lève.There are seats of this type, in which the envelope which is, for example, made of a textile material or a material waterproof synthetic, has an interior volume greater than the volume of constituent balls of the filling elements. It is thus possible to move the balls inside the pocket, to allow different conformations of the seat, and in particular to adapt the seat to the shape of the body of the user, when seated. However, seats of this type have an unpleasant aesthetic, insofar as there is a surplus envelope to allow the displacement of the polystyrene beads, and the seat remaining, when the user leaves it, in the position in which it was before the user got up.

Le but de l'invention est de fournir un siège de ce type, qui soit auto-adaptable à la forme du corps d'un ou de plusieurs utilisateurs, et qui revienne automatiquement dans une position d'origine lorsque l'utilisateur se lève, afin de procurer au siège une excellente esthétique, en période de non utilisation.The object of the invention is to provide a seat of this type, which is self-adaptable to the body shape of one or more users, and who automatically returns to an original position when the user gets up, to give the seat an excellent aesthetic, during not used.

A cet effet, le siège qu'elle concerne, du type précité, comportant une enveloppe à l'intérieur de laquelle sont disposés des éléments de remplissage non compressibles, tels que des billes de polystyrène, est caractérisé en ce qu'il comprend une paroi inférieure et des parois latérales en matériau rigide, semi-rigide et/ou imperméable, et une paroi supérieure dont une partie au moins est réalisée en un matériau élastique et perméable, les éléments de remplissage occupant la totalité du volume délimité par les parois inférieure, latérales et supérieure.For this purpose, the seat it concerns, of the aforementioned type, comprising an envelope inside which are arranged non-compressible filling elements, such as balls polystyrene, is characterized in that it comprises a lower wall and side walls made of rigid, semi-rigid and / or waterproof material, and an upper wall, at least part of which is made of a material elastic and permeable, the filling elements occupying the entire volume delimited by the lower, side and upper walls.

Lorsque l'utilisateur s'assied sur la face supérieure du siège, celle-ci se déforme en formant un creux dans la zone d'assise, les billes se déplaçant pour former un dossier dans une zone où la pression est moindre. Ce déplacement est rendu possible, bien que les éléments de remplissage occupent tout le volume utile, dans la mesure où l'air peut circuler à travers le matériau constitutif de la paroi supérieure. En outre, cette déformation de la partie supérieure est également rendue possible en raison du blocage latéral réalisé par les parois latérales, compte tenu de la nature du matériau constitutif de celles-ci. Lorsque l'utilisateur se relève, la perméabilité du matériau constitutif de la paroi supérieure associée à l'élasticité de ce matériau assure un nouveau déplacement des éléments de remplissage jusqu'à ce que la paroi supérieure forme une surface continue.When the user sits on the upper side of the seat, it deforms, forming a hollow in the seating area, the balls moving to form a folder in an area where pressure is lesser. This displacement is made possible, although the elements of filling occupies the entire usable volume, as far as air can circulate through the material of the upper wall. In addition, this deformation of the upper part is also made possible by because of the lateral blocking carried out by the side walls, taking into account the nature of the material of which they are made. When the user gets up, the permeability of the material of the upper wall associated with the elasticity of this material ensures a new displacement of the elements filling until the top wall forms a surface keep on going.

Afin de favoriser le blocage latéral des éléments de remplissage, les parois latérales comportent un retour réalisé dans le même matériau, au niveau de la paroi supérieure.In order to favor the lateral blocking of the elements of filling, the side walls have a return made in the same material, at the level of the upper wall.

Suivant une caractéristique de l'invention, la paroi inférieure et/ou les parois latérales sont réalisées en une nappe de matériau souple, imperméable et inextensible.According to a characteristic of the invention, the lower wall and / or the side walls are made of a sheet of flexible material, waterproof and inextensible.

Suivant une possibilité dans ce cas, les parois inférieure, latérales et supérieure sont assemblées les unes aux autres, par exemple par couture, et forment une poche contenant les éléments de remplissage.According to one possibility in this case, the lower walls, side and top are joined together, for example by sewing, and form a pocket containing the filling elements.

Selon une autre forme d'exécution de ce siège, les parois latérales sont constituées par une ceinture, à l'intérieur de laquelle est disposée au moins une poche contenant les éléments de remplissage, dont la paroi supérieure est réalisée en matériau élastique et perméable.According to another embodiment of this seat, the walls side consist of a belt, inside which is arranged at least one pocket containing the filling elements, of which the upper wall is made of elastic and permeable material.

Suivant une première possibilité dans ce cas, la ceinture est constituée par un panneau rigide.According to a first possibility in this case, the belt is constituted by a rigid panel.

Suivant une autre possibilité, la ceinture est constituée par un boudin en matériau homogène, tel qu'en caoutchouc ou en mousse de matière synthétique ou par un boudin gonflable.According to another possibility, the belt is constituted by a tube of homogeneous material, such as rubber or foam synthetic material or by an inflatable tube.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, plusieurs formes d'exécution de ce siège :

  • Figure 1 est une vue en perspective d'un premier siège possédant une forme générale de pouf ;
  • Figures 2 et 3 en sont deux vues en coupe transversale respectivement en position de non utilisation et en position d'utilisation ;
  • Figures 4 et 5 sont deux vues en coupe transversale de deux autres sièges, en position de non utilisation.
    • In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, several embodiments of this seat:
  • Figure 1 is a perspective view of a first seat having a general shape of pouffe;
  • Figures 2 and 3 are two cross-sectional views respectively in the non-use position and the use position;
  • Figures 4 and 5 are two cross-sectional views of two other seats, in the non-use position.

    • La figure 1 représente un pouf de forme générale cylindrique comportant une paroi inférieure 2 constituée par une nappe de matériau imperméable et inextensible, prolongée par une paroi latérale 3 constituée dans ce même matériau, cette paroi latérale comportant un retour périphérique 4 au niveau de la paroi supérieure. Le centre de la paroi supérieure est réalisé en une nappe de matériau 5 élastique et perméable. Ces différentes parois 2, 3 et 5 délimitent un volume qui est entièrement rempli par des éléments de remplissage 6 de petites dimensions, tels que des billes de polystyrène.Figure 1 shows a generally cylindrical pouffe having a bottom wall 2 constituted by a sheet of material waterproof and inextensible, extended by a side wall 3 made up in this same material, this side wall comprising a return device 4 at the level of the upper wall. The center of the wall upper is made of a sheet of elastic and permeable material. These different walls 2, 3 and 5 define a volume which is entirely filled with filling elements 6 of small dimensions, such as polystyrene beads.

    Lorsque le pouf est en position de non utilisation, il possède la forme représentée à la figure 2. Lorsqu'un utilisateur s'assied sur le pouf, il s'exerce, au niveau de l'assise, une pression F vers le bas, ayant tendance à former un creux par déplacement des billes dans les zones où s'exerce une moindre pression. Les billes sont bloquées latéralement par la paroi latérale, compte tenu de la nature du matériau constitutif de celle-ci. Compte tenu de la perméabilité de la paroi supérieure 5, l'air peut s'échapper dans les zones où existe une moindre pression, comme représenté par des flèches à la figure 3, les billes pouvant se déplacer dans cette zone et former un dossier pour l'utilisateur.When the pouffe is in the non-use position, it has the shape shown in Figure 2. When a user sits on the ottoman, there is pressure, at the level of the seat, downward pressure F, having tendency to form a hollow by displacement of the balls in the zones where less pressure is exerted. The balls are blocked laterally by the side wall, taking into account the nature of the material from which it is made. Given the permeability of the upper wall 5, the air can escape into areas where there is less pressure, such as represented by arrows in figure 3, the balls being able to move in this area and form a folder for the user.

    Lorsque l'utilisateur se relève, le phénomène inverse se produit, sous l'effet de l'élasticité de la paroi supérieure 5, et le pouf revient dans la position de la figure 2, dans laquelle il possède une esthétique parfaite.When the user gets up, the opposite phenomenon occurs, under the effect of the elasticity of the upper wall 5, and the pouffe returns to the position of Figure 2, in which it has a perfect aesthetic.

    La figure 4 représente une seconde forme d'exécution d'un siège selon l'invention, dans lequel la paroi extérieure 7 est constituée par un boudin indépendant d'une poche 8 contenant des éléments de remplissage 9. Le boudin 7 peut être réalisé en caoutchouc ou en mousse, ou être rempli d'air, l'essentiel étant qu'il assure un blocage des éléments de remplissage pour éviter tous mouvements de ceux-ci vers l'extérieur lorsqu'une pression est exercée sur la poche 8. Comme dans la forme d'exécution précédente, au moins la paroi supérieure 10 de la poche 8 est réalisée en une nappe d'un matériau élastique et perméable.Figure 4 shows a second embodiment of a seat according to the invention, in which the outer wall 7 consists of a sausage independent of a pocket 8 containing elements of filling 9. The flange 7 can be made of rubber or foam, or be filled with air, the main thing being that it blocks the elements filling to avoid any movement of these outwards when pressure is exerted on the pocket 8. As in the form previous execution, at least the upper wall 10 of the pocket 8 is made of a sheet of elastic and permeable material.

    La figure 5 représente un siège qui constitue une variante d'exécution du siège de la figure 4, dans lequel les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, la partie centrale du siège est constituée non pas par une poche 8, mais par trois poches 8.FIG. 5 represents a seat which constitutes a variant execution of the seat of Figure 4, in which the same elements are designated by the same references as above. In this case central part of the seat is formed not by a pocket 8, but by three pockets 8.

    Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un siège de structure simple, qui est auto-adaptable à la forme du corps du ou des utilisateurs, et qui revient dans sa position d'origine, dès que toute pression a cessé d'être exercée sur lui.As is apparent from the above, the invention provides a great improvement to the existing technique by providing a seat for simple structure, which is self-adapting to the body shape of the users, and which returns to its original position, as soon as any pressure has ceased to be exerted on him.

    Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce siège, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que les parois latérales pourraient être constituées par des panneaux rigides, ou encore que la paroi supérieure du siège pourrait comporter plusieurs zones réalisées en matériau élastique et perméable, sans que l'on sorte pour autant du cadre de l'invention.It goes without saying that the invention is not limited only to embodiments of this seat, described above by way of example, it on the contrary embraces all variants. This is how in particular the side walls could be formed by rigid panels, or that the upper wall of the seat could include several zones made of elastic and permeable material, without leaving however within the scope of the invention.
