Description

1 La présente invention a pour objet un matelas. Des matelas connusThe present invention relates to a mattress. Known mattresses

comprennent une nappe de suspension à ressorts disposée entre une nappe inférieure et une nappe supérieure, qui sont par exemple réalisées en mousse. De tels matelas permettent d'obtenir une fermeté uniforme prédéfinie sur toute leur surface supérieure. Une telle uniformité peut cependant être préjudiciable au confort de l'usager dont certaines parties du corps nécessitent un meilleur soutien que d'autres. La présente invention a pour but de proposer un matelas qui évite l'inconvénient précité et qui permette de moduler la fermeté, de la tête jusqu'au pied du matelas, pour atteindre un confort optimal de l'usager. A cet effet, l'invention a pour objet un matelas comportant une nappe inférieure, une nappe supérieure, et une nappe de suspension disposée entre ladite nappe inférieure et ladite nappe supérieure, ladite nappe de suspension comportant des ressorts, caractérisé en ce que ladite nappe de suspension comporte des éléments de suspension insérés entre lesdits ressorts dans la direction longitudinale dudit matelas. Avantageusement, au moins un desdits éléments de suspension comporte un ensemble de zones d'élément réparties sur sa longueur, chacune desdites zones d'élément étant caractérisée par sa densité ou dureté. De préférence, lesdits éléments de suspension sont identiques entre eux et disposés parallèlement les uns par rapport aux autres. Selon un mode de réalisation de l'invention, ladite nappe supérieure 25 comporte un ensemble de zones de nappe, chacune desdites zones de nappe étant caractérisée par sa densité ou dureté. Avantageusement, lesdites zones de nappe forment des bandes disposées selon une direction latérale dudit matelas et sont destinées à coopérer avec lesdites zones d'élément.  comprise a spring-shaped suspension ply arranged between a lower ply and an upper ply, which are for example made of foam. Such mattresses make it possible to obtain a predefined uniform firmness over their entire upper surface. Such uniformity may, however, be detrimental to user comfort, with some parts of the body requiring better support than others. The present invention aims to provide a mattress that avoids the aforementioned drawback and that allows to modulate the firmness, from the head to the foot of the mattress, to achieve optimum comfort of the user. For this purpose, the subject of the invention is a mat comprising a lower ply, an upper ply, and a suspension ply disposed between said lower ply and said upper ply, said ply comprising springs, characterized in that said ply suspension comprises suspension elements inserted between said springs in the longitudinal direction of said mattress. Advantageously, at least one of said suspension elements comprises a set of element zones distributed over its length, each of said element zones being characterized by its density or hardness. Preferably, said suspension elements are identical to each other and arranged parallel to one another. According to one embodiment of the invention, said upper ply 25 comprises a set of ply zones, each of said ply zones being characterized by its density or hardness. Advantageously, said ply areas form strips arranged in a lateral direction of said mat and are intended to cooperate with said element areas.

2909535 2 Selon un mode de réalisation de l'invention, lesdits ressorts sont assemblés mécaniquement entre eux à partir de fil d'acier haute résistance. De préférence, ladite nappe inférieure est identique à ladite nappe supérieure.According to one embodiment of the invention, said springs are mechanically assembled together from high strength steel wire. Preferably, said lower ply is identical to said upper ply.

5 L'invention sera mieux comprise, et d'autres buts, détails, caractéristiques et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative détaillée qui va suivre, d'un mode de réalisation de l'invention donné à titre d'exemple purement illustratif et non limitatif, en référence aux dessins schématiques annexés.The invention will be better understood, and other objects, details, features and advantages thereof will become more clearly apparent from the following detailed explanatory description of an embodiment of the invention given by way of purely illustrative and non-limiting example, with reference to the accompanying schematic drawings.

10 Sur ces dessins : - la figure 1 est une vue schématique simplifiée en perspective d'un matelas selon un mode de réalisation de l'invention ; - la figure 2 est un graphique représentant une série de courbes montrant l'enfoncement de différentes zones du matelas de la figure 1 du fait 15 des ressorts et des éléments de suspension d'une nappe de suspension du matelas, en fonction de la force exercée sur le matelas ; et - la figure 3 est un graphique représentant une série de courbes montrant l'enfoncement de différentes zones du matelas de la figure 1 du fait des ressorts de la nappe de suspension et d'une nappe supérieure du 20 matelas, en fonction de la force exercée sur le matelas. En se référant à la figure 1, on voit un matelas 1 comportant une enveloppe 2 (partiellement représentée sur la figure 1), qui est par exemple réalisée en mousse. L'enveloppe 2 comporte quatre bords, à savoir deux bords latéraux 3, un bord avant et un bord arrière, chaque bord présentant une forme sensiblement parallélépipédique. La longueur des bords latéraux 3 correspond à la longueur du matelas 1, la longueur des bords avant et arrière correspond à la largeur du matelas 1, et la largeur des bords latéraux 3, avant et arrière correspond à la hauteur du matelas 1. Les bords avant et arrière n'ont pas été représentés sur la figure 1 par souci de clarté. L'enveloppe 2 comporte une nappe inférieure 4 et une nappe supérieure 5, 2909535 3 chaque nappe 4, 5 ayant une forme de plaque rectangulaire, de largeur égale à la longueur des bords avant et arrière et de longueur égale à la longueur des bords latéraux 3. Le matelas 1 comprend, à l'intérieur de l'enveloppe 2, une nappe de 5 suspension 6. La nappe de suspension 6 comprend des ressorts 8 qui sont assemblés mécaniquement entre eux à partir de fil d'acier haute résistance. Les ressorts 8 sont par exemple réalisés, de manière connue en soi, par le tricotage d'un fil continu d'acier traité haute résistance en spires. Le fil d'acier a par exemple un diamètre compris entre 16/10è"1e et 19/10ème de millimètres.In these drawings: - Figure 1 is a simplified schematic perspective view of a mattress according to one embodiment of the invention; FIG. 2 is a graph showing a series of curves showing the depression of different areas of the mattress of FIG. 1 due to the springs and suspension elements of a mattress web, depending on the force exerted. on the mattress; and FIG. 3 is a graph showing a series of curves showing the depression of different areas of the mattress of FIG. 1 due to the springs of the suspension ply and an upper ply of the mattress, depending on the force. exercised on the mattress. Referring to Figure 1, there is shown a mattress 1 having an envelope 2 (partially shown in Figure 1), which is for example made of foam. The envelope 2 has four edges, namely two lateral edges 3, a front edge and a rear edge, each edge having a substantially parallelepiped shape. The length of the side edges 3 corresponds to the length of the mattress 1, the length of the front and rear edges corresponds to the width of the mattress 1, and the width of the side edges 3, front and rear corresponds to the height of the mattress 1. The edges front and rear have not been shown in Figure 1 for the sake of clarity. The envelope 2 comprises a lower ply 4 and an upper ply 5, each ply 4, 5 having a rectangular plate shape, of width equal to the length of the front and rear edges and of length equal to the length of the lateral edges. 3. The mattress 1 comprises, inside the casing 2, a suspension ply 6. The suspension ply 6 comprises springs 8 which are mechanically joined to each other from high-strength steel wire. The springs 8 are for example made, in a manner known per se, by the knitting of a continuous thread of high-strength treated steel in turns. The steel wire has for example a diameter of between 16 / 10th and 19 / 10th of a millimeter.

10 L'enveloppe 2 est destinée à être recouverte par une housse (non représentée) en tissu. La nappe de suspension 6 comporte des éléments de suspension 7, par exemple réalisés en mousse, qui sont insérés dans le fil d'acier formant les ressorts 8, c'est-à-dire entre les ressorts 8. Par exemple, les éléments 7 15 sont disposés parallèlement les uns aux autres dans la direction longitudinale X du matelas 1, en deux couches superposées, c'est-à-dire que les éléments 7 sont superposés par paire dans la direction de l'épaisseur Z du matelas 1. Les éléments 7 sont par exemple espacés les uns des autres dans la direction latérale Y du matelas 1 d'une distance correspondant sensiblement 20 à la largeur d'un élément 7. Chaque élément 7 présente globalement la forme d'un parallélépipède dont la section transversale est amincie dans sa zone médiane. Chaque élément 7 comporte un ensemble de zones réparties sur sa longueur, par exemple sept zones 7a à 7g. Une zone 7a à 7g est caractérisée par sa 25 densité ou dureté, qui peut varier d'une zone à l'autre. Les zones 7a à 7g sont réparties de manière similaire sur chacun des éléments 7, c'est-à-dire que la nappe de suspension 6 comporte des zones 6a à 6g, formant des bandes disposées selon la direction latérale Y du matelas 1, chaque bande 6a à 6g étant caractérisée par sa densité ou dureté.The envelope 2 is intended to be covered by a fabric cover (not shown). The suspension ply 6 comprises suspension elements 7, for example made of foam, which are inserted into the steel wire forming the springs 8, that is to say between the springs 8. For example, the elements 7 15 are arranged parallel to each other in the longitudinal direction X of the mattress 1, in two superposed layers, that is to say that the elements 7 are superimposed in pairs in the direction of the thickness Z of the mattress 1. The elements 7 are for example spaced apart from each other in the lateral direction Y of the mattress 1 by a distance substantially corresponding to the width of an element 7. Each element 7 generally has the shape of a parallelepiped whose cross-section is thinned in its median area. Each element 7 comprises a set of zones distributed over its length, for example seven zones 7a to 7g. An area 7a-7g is characterized by its density or hardness, which may vary from area to area. The zones 7a to 7g are similarly distributed on each of the elements 7, that is to say that the suspension ply 6 comprises zones 6a to 6g, forming strips arranged in the lateral direction Y of the mattress 1, each band 6a to 6g being characterized by its density or hardness.

30 La nappe supérieure 5 comporte également un ensemble de zones, par exemple sept zones 5a à 5g, chaque zone 5a à 5g étant caractérisée par sa densité ou dureté. Les zones 5a à 5g forment des bandes disposées 2909535 4 selon la direction latérale Y du matelas 1, chaque zone 5a à 5g étant disposée au droit d'une zone 6a à 6g. L'utilisation de zones 5a à 5g et 7a à 7g de différentes densités permet de moduler la fermeté du plan de couchage du matelas 1 d'une part via la nappe de suspension 6 et d'autre 5 part via la nappe supérieure 5. La nappe inférieure 4 peut être identique à la nappe supérieure 5 pour que le matelas 1 puisse être utilisé indifféremment des deux côtés. La figure 2 montre des courbes 11 à 13 représentant l'enfoncement en millimètres (axe x) de trois zones du matelas, respectivement, du fait de la 10 nappe de suspension 6, en fonction de la force exercée sur le matelas 1 en Newton (axe y). La courbe 13 représente l'enfoncement de la zone 6b, destinée à soutenir les épaules d'une personne. La courbe 12 représente l'enfoncement de la zone 6d, destinée à soutenir les lombaires de la personne. La courbe 11 représente l'enfoncement de la zone 6e, destinée à 15 soutenir la lordose de la personne. Ainsi, pour une force donnée, l'enfoncement du matelas 1 est moins important dans la zone 6e que dans la zone 6d et dans la zone 6d que dans la zone 6b. Le matelas 1 permet donc un soutien adapté aux différentes parties du corps, ce qui a pour effet un meilleur confort de la personne. A titre comparatif, la courbe 14 représente 20 l'enfoncement d'un matelas dont la couche de suspension comprend uniquement des ressorts. La figure 3 montre des courbes 15 à 17 représentant l'enfoncement en millimètres (axe x) de trois zones du matelas 1, respectivement, du fait des ressorts 8 et de la nappe supérieure 5, en fonction de la force exercée sur le 25 matelas 1 en Newton (axe y). La courbe 17 représente l'enfoncement de la zone 5b, destinée à soutenir les épaules d'une personne. La courbe 162 représente l'enfoncement de la zone 5d, destinée à soutenir les lombaires de la personne. La courbe 15 représente l'enfoncement de la zone 5e, destinée à soutenir la lordose de la personne. Les zones 5b, 5d et 5e sont associées 30 respectivement aux zones 6b, 6d et 6e, l'enfoncement du matelas 1 étant moins important dans la zone 5e que dans la zone 5d et dans la zone 5d que dans la zone 5b. La nappe 5 coopère donc avec la nappe 6 pour réaliser la 2909535 5 segmentation morphologique du matelas 1, ce qui a pour effet un meilleur confort de la personne. Bien que l'invention ait été décrite en relation avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et 5 qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.The upper ply 5 also comprises a set of zones, for example seven zones 5a to 5g, each zone 5a to 5g being characterized by its density or hardness. The zones 5a to 5g form bands arranged in the lateral direction Y of the mattress 1, each zone 5a to 5g being arranged in line with an area 6a to 6g. The use of zones 5a to 5g and 7a to 7g of different densities makes it possible to modulate the firmness of the coating plane of the mattress 1 on the one hand via the suspension ply 6 and on the other hand via the upper ply 5. lower sheet 4 may be identical to the upper sheet 5 so that the mattress 1 can be used indifferently on both sides. FIG. 2 shows curves 11 to 13 showing the depression in millimeters (x axis) of three zones of the mattress, respectively, because of the suspension ply 6, as a function of the force exerted on the mattress 1 in Newton ( y axis). Curve 13 represents the depression of zone 6b, intended to support the shoulders of a person. Curve 12 represents the depression of zone 6d, intended to support the lumbar of the person. Curve 11 represents the depression of zone 6e, intended to support the lordosis of the person. Thus, for a given force, the depression of the mattress 1 is less important in the zone 6e than in the zone 6d and in the zone 6d that in the zone 6b. The mattress 1 thus allows a support adapted to different parts of the body, which has the effect of a better comfort of the person. By way of comparison, curve 14 represents the depression of a mattress whose suspension layer comprises only springs. FIG. 3 shows curves 15 to 17 showing the depression in millimeters (x-axis) of three zones of the mattress 1, respectively, because of the springs 8 and the upper ply 5, as a function of the force exerted on the mattress 1 in Newton (y axis). Curve 17 represents the depression of zone 5b, intended to support the shoulders of a person. The curve 162 represents the depression of the zone 5d, intended to support the lumbar of the person. Curve 15 represents the depression of the zone 5e, intended to support the lordosis of the person. Zones 5b, 5d and 5e are respectively associated with zones 6b, 6d and 6e, the depression of the mattress 1 being less important in zone 5e than in zone 5d and in zone 5d than in zone 5b. The web 5 thus cooperates with the web 6 to achieve the morphological segmentation of the mattress 1, which has the effect of a better comfort of the person. Although the invention has been described in connection with a particular embodiment, it is quite obvious that it is in no way limited and that it includes all the technical equivalents of the means described as well as their combinations if these These are within the scope of the invention.
