Description

La présente invention se rapporte à tous types de sièges d'ameublement, de véhicules, etc. comportant des moyens de suspension permettant d'apporter à l'utilisateur le support et le confort désirés.The present invention relates to all types of furniture seats, vehicles, etc. comprising suspension means making it possible to provide the user with the desired support and comfort.

On connaît déjà des sièges, notamment pour véhicules, qui comportent un fond et un dossier fixés chacun respectivement à un cadre inférieur et à un cadre supérieur au moyen d'éléments élastiques, par exemple des ressorts hélicoïdaux, le tout étant recouvert selon la destination prévue du siège d'un rembourrage et/ou d'une garniture extérieure. Généralement, le fond et le dossier suspendus aux cadres sont formés d'un treillis métallique rigide. Toutefois, le confort offert par ce type de siège n'est pas toujours satisfaisant, notamment dans le cas d'un véhicule automobile dans lequel l'usager est soumis à des mouvements répétés et brusques. De plus, les ressorts de suspension du fond et du dossier étant très sollicités, ils perdent relativement rapidement leurs caractéristiques élastiques et la suspension devient insuffisante. Enfin, dans ce type de siège, il est nécessaire de prévoir des cadres suffisamment solides et épais pour supporter l'affaiblissement dû aux orifices pratiqués en vue de l'accrochage des ressorts de suspension.There are already known seats, in particular for vehicles, which have a bottom and a back, each fixed respectively to a lower frame and to an upper frame by means of elastic elements, for example helical springs, the whole being covered according to the intended destination. of the seat with padding and / or an exterior trim. Generally, the bottom and the back hanging from the frames are formed of a rigid wire mesh. However, the comfort offered by this type of seat is not always satisfactory, in particular in the case of a motor vehicle in which the user is subjected to repeated and sudden movements. In addition, the suspension springs of the bottom and the backrest being very stressed, they lose their elastic characteristics relatively quickly and the suspension becomes insufficient. Finally, in this type of seat, it is necessary to provide frames which are sufficiently solid and thick to withstand the weakening due to the orifices made for hooking the suspension springs.

Il est également connu du brevet US-A-3.137.489 un siège comportant au cadre inférieur et un cadre supérieur sur lesquels sont fixées des surfaces portantes formant respectivement le fond et le dossier. Au moins une de ces surfaces portantes est constituée par une nappe élastique formée de fils transversaux. Chacun des ces fils ressort comporte des boucles permanentes situées approximativement dans le plan de la nappe. La fabrication de ces boucles est relativement compliquée.It is also known from US-A-3,137,489 a seat comprising at the lower frame and an upper frame on which are fixed bearing surfaces respectively forming the bottom and the backrest. At least one of these bearing surfaces is constituted by an elastic sheet formed of transverse threads. Each of these spring wires has permanent loops located approximately in the plane of the sheet. The manufacture of these loops is relatively complicated.

Le but de cette invention consiste à fournir un siège qui ne présente pas les inconvénients des sièges connus précités. Ce but est atteint par le siège, objet de l'invention, qui comporte un cadre inférieur et un cadre supérieur sur lesquels sont fixées des surfaces portantes formant respectivement le fond et le dossier, dans lequel au moins une des surfaces portantes est constituée par une nappe élastique formée de fils disposés transversalement, chaque fil présentant au moins une déformation permanente située de préférence dans le plan de la nappe, et qui est caractérisé par le fait que ces déformations permanentes sont élastiques et présentent une portion linéaire décalée parallèlement par rapport au reste du fil et reliée à celui-ci par deux portions obliques.The object of this invention is to provide a seat which does not have the disadvantages of the aforementioned known seats. This object is achieved by the seat, object of the invention, which comprises a lower frame and an upper frame on which are fixed bearing surfaces respectively forming the bottom and the backrest, in which at least one of the bearing surfaces is constituted by a elastic ply formed of wires arranged transversely, each wire having at least one permanent deformation preferably situated in the plane of the ply, and which is characterized by the fact that these permanent deformations are elastic and have a linear portion offset parallel to the rest of the wire and connected to it by two oblique portions.

Certains sièges connus, destinés plus particulièrement à équiper des automobiles, sont du type illustré sur la figure 1 et comportent deux cadres respectivement supérieur 1 et inférieur 2 généralement métalliques et réalisés par des pièces embouties, des profilés ou des éléments tubulaires. Les surfaces portantes ou de support, à savoir le dossier et le fond, peuvent être constituées par des treillis métalliques 3, 4, fixés à des baguettes latérales 5, 6. Chaque ensemble rigide treillis-baguettes latérales est fixé latéralement au cadre respectivement supérieur et inférieur au moyen de ressort 7, 8, ceux-ci étant d'une part accrochés aux baguettes latérales 5, 6 et d'autre part fixés dans des orifices pratiqués dans les cadres respectifs 1, 2. Bien entendu, les cadres et les treillis sont recouverts par exemple avec de la mousse plastiques et un tissu ou un autre matériau extérieur enveloppant celle-ci afin de constituer la siège fini.Certain known seats, intended more particularly for equipping automobiles, are of the type illustrated in FIG. 1 and comprise two respectively upper 1 and lower 2 frames, generally metallic and produced by stamped parts, profiles or tubular elements. The bearing or support surfaces, namely the backrest and the bottom, can be constituted by wire mesh 3, 4, fixed to lateral strips 5, 6. Each rigid mesh-lateral strip assembly is fixed laterally to the respectively upper frame and lower by means of spring 7, 8, these being on the one hand hooked to the side rods 5, 6 and on the other hand fixed in orifices made in the respective frames 1, 2. Of course, the frames and the trellises are covered for example with plastic foam and a fabric or other external material enveloping it in order to constitute the finished seat.

Sur la figure 2 est illustrée une réalisation d'une nappe élastique 10 fixée au cadre supérieur 11 d'un siège selon l'invention et constituant le dossier der celui-ci. Cette nappe 10 est formée d'une pluralité de fils métalliques 12 disposés transversalement pratiquement parallèlement les uns aux autres. Chaque fil présente une déformation élastique permanente 13, ici dans la portion médiane du fil. Celui-ci peut être constitué dans un fil de fer, ou de préférence d'un fil en acier ressort normal ou trempé (par exemple selon norme DIN 2076).In FIG. 2 is illustrated an embodiment of an elastic sheet 10 fixed to the upper frame 11 of a seat according to the invention and constituting the backrest thereof. This sheet 10 is formed of a plurality of metal wires 12 arranged transversely practically parallel to one another. Each wire has a permanent elastic deformation 13, here in the middle portion of the wire. This can be made of an iron wire, or preferably of a normal or hardened spring steel wire (for example according to standard DIN 2076).

La déformation que présente chaque fil est de préférence située dans un plan, et plus particulièrement celui de la nappe; sa géométrie peut être celle illustrée sur la figure 2, c'est-à-dire avec une portion linéaire décalée parallèlement par rapport au reste du fil et reliée à celui-ci par deux portions obliques (ci-après désignée comme forme «en cuvette»). Le fil peut présenter sur sa longueur une seule ou plusieurs de ces déformations.The deformation presented by each wire is preferably located in a plane, and more particularly that of the sheet; its geometry can be that illustrated in FIG. 2, that is to say with a linear portion offset parallel to the rest of the wire and connected to it by two oblique portions (hereinafter referred to as "bowl" shape "). The wire can have one or more of these deformations along its length.

Les fils transversaux 12 sont de préférence fixés par leurs extrémités aux branches latérales d'un élément-support 14 ici en forme de U. L'élément-support 14 portant la nappe élastique ou ressort 10 est fixé au cadre au moyen de clips 15 pincés sur le tube 11 constituant ce cadre. Les figures 6 et 7 illustrent deux variantes 15,15' de ces clips, qui peuvent être réalisées en acier ressort, en matière plastique, etc.The transverse wires 12 are preferably fixed by their ends to the lateral branches of a support element 14 here in the shape of a U. The support element 14 carrying the elastic sheet or spring 10 is fixed to the frame by means of clips 15 pinched on the tube 11 constituting this frame. Figures 6 and 7 illustrate two variants 15,15 'of these clips, which can be made of spring steel, plastic, etc.

Pour maintenir l'écartement entre les fils 12 constituant la nappe élastique 10, des éléments 16 sont disposés dans le plan de la nappe perpendiculairement aux-dits fils, ceux-ci passant dans des orifices transversaux pratiqués dans ces éléments à intervales réguliers. Ces éléments d'écartement 16 peuvent par exemple être constitués de cordes en polypropylène.To maintain the spacing between the wires 12 constituting the elastic ply 10, elements 16 are arranged in the plane of the ply perpendicular to said wires, the latter passing through transverse orifices made in these elements at regular intervals. These spacers 16 may for example be made of polypropylene cords.

La coupe de la figure 3 permet de mieux illustrer d'une part le fait que la déformation 13 que présente la partie médiane du fil 12 est bien dans le plan de la nappe, et d'autre part la fixation du support 14 de la nappe au cadre tubulaire 11 au moyen du clips 15. Quant à la coupe de la figure 4, elle montre la déformation du fil 12 sous l'effet d'une poussée selon les flèches V due par exemple à l'appui contre le dossier du dos de l'utilisateur du siège.The section of FIG. 3 makes it possible to better illustrate on the one hand the fact that the deformation 13 presented by the middle part of the wire 12 is indeed in the plane of the sheet, and on the other hand the fixing of the support 14 of the sheet to the tubular frame 11 by means of the clips 15. As for the section of FIG. 4, it shows the deformation of the wire 12 under the effect of a push according to the arrows V due for example to the support against the backrest of the back of the seat user.

Enfin, la figure 5 montre plus en détail et en plan la déformation élastique 13 du fil 12. En trait plein est illustrée la position du fil 12 avant l'assemblage de la nappe sur le cadre. Le rapport entre les dimensions des portions obliques 13' et de la portion linéaire décalée 13" de la déformation en forme de cuvette peut être modifié selon l'effet ressort recherché. En trait interrompu est illustrée la forme de la déformation 13 dans la position de repos du fil 12, la nappe élastique étant fixée au cadre et les montants-supports 14 étant légèrement plus écartés l'un de l'autre, alors que les traits mixtes illustrent la forme de ladite déformation 13 lorsque le fil 12 est sollicité par une poussée sensiblement perpendiculaire au plan de la nappe ressort.Finally, Figure 5 shows in more detail and in plan the elastic deformation 13 of the wire 12. In solid line is illustrated the position of the wire 12 before the assembly of the sheet on the frame. The ratio between the dimensions of the oblique portions 13 ′ and of the offset linear portion 13 ″ of the cup-shaped deformation can be modified according to the desired spring effect. In dashed line is illustrated the shape of the deformation 13 in the position of rest of the wire 12, the elastic sheet being fixed to the frame and the support uprights 14 being slightly more apart from one another, while the dashed lines illustrate the shape of said deformation 13 when the wire 12 is stressed by a thrust substantially perpendicular to the plane of the spring ply.

Comme dans le cas des sièges de type classique, le siège selon l'invention tel qu'il a été décrit ci-dessus en référence aux dessins est encore recouvert par exemple avec une mousse plastique, un tissu ou un autre matériau eveloppant celle-ci pour constituer le siège fini.As in the case of seats of the conventional type, the seat according to the invention as described above with reference to the drawings is still covered, for example, with a plastic foam, a fabric or another material enveloping it. to constitute the finished seat.

Par rapport au sièges avec suspension connus, le siège selon l'invention présente notamment l'avantage d'être plus confortable, la nappe ressort présentant de meilleures caractéristiques d'élasticité qu'un treillis rigide suspendu latéralement, du fait qu'elle s'étend sur une partie au moins de la surface portante. En outre, la possibilité de prévoir différentes formes de déformations et de les disposer différemment sur la surface de la nappe élastique permet de conférer au siège selon l'invention des caractéristiques élastiques différentes et réparties différemment en fonction, par exemple, de la garniture extérieure envisagée du siège (forme et élasticité propre du rembourrage notamment), de la nature du véhicule destiné à être équipé du siège (automobile utilitaire, de luxe, de sport, etc.) et d'autres facteurs tels que le poids de l'utilisateur, caractéristiques de la suspension du véhicule, etc.Compared to known suspension seats, the seat according to the invention has the particular advantage of being more comfortable, the spring ply having better elasticity characteristics than a rigid trellis suspended laterally, because it s extends over at least part of the bearing surface. In addition, the possibility of providing different forms of deformation and of arranging them differently on the surface of the elastic ply allows the seat according to the invention to be given different elastic characteristics which are distributed differently depending, for example, on the external lining envisaged. the seat (shape and elasticity of the padding in particular), the nature of the vehicle intended to be fitted with the seat (utility, luxury, sports car, etc.) and other factors such as the weight of the user, vehicle suspension characteristics, etc.

De plus la fixation de la nappe élastique sur le cadre au moyen de simples clips d'une part facilite la fabrication, puisqu'elle évite le percement d'orifices dans le cadre et permet l'utilisation de cadres tubulaires légers, et d'autre part permet la livraison en pièces détachées du siège et rend son assemblée final aisé.In addition, the fixing of the elastic sheet to the frame by means of simple clips on the one hand facilitates manufacture, since it avoids the drilling of orifices in the frame and allows the use of light tubular frames, and on the other part allows the delivery in parts of the seat and makes its final assembly easy.

Enfin, la suppression des ressorts hélicoïdaux habituellement utilisés pour suspendre le fond et le dossier des sièges conus, et qui sont généralement au nombre de huit, et leur remplacement par de simples clips (par exemple six) dans le siège selon l'invention, permet d'obtenir pour celui-ci un gain de poids appréciable.Finally, the removal of the coil springs usually used to suspend the bottom and back of the designed seats, which are generally eight in number, and their replacement by simple clips (for example six) in the seat according to the invention, allows obtain an appreciable weight gain for the latter.
