Description

La présente invention se rapporte à un siège, notamment un siège de travail, à plusieurs positions, comprenant un châssis monté de préférence de façon réglable en hauteur sur un pied et supportant une structure de soutien du corps, formée d'au moins deux parties comprenant une assise et un dossier reliés de façon articulée entre eux, l'assise étant directement articulée sur le châssis et le dossier étant articulé sur une console de soutien elle-même articulée sur le châssis, de telle manière que les positions de l'assise et du dossier puissent être modifiées conjointement, des moyens étant prévus pour maintenir la console dans les différentes positions.The present invention relates to a seat, in particular a work seat, with several positions, comprising a chassis preferably mounted in height-adjustable manner on a foot and supporting a body support structure, formed of at least two parts comprising a seat and a backrest hingedly linked together, the seat being directly articulated on the chassis and the backrest being articulated on a support console itself articulated on the chassis, so that the positions of the seat and of the backrest can be modified jointly, means being provided to maintain the console in the different positions.

Les sièges connus de ce type nécessitent des moyens de structure compliquée pour assurer la modification de position conjointe des parties de la structure de soutien du corps et où cette structure de soutien du corps ne maintient pas de façon optimale les parties du corps dans toutes les positions.Known seats of this type require complicated structural means to ensure the joint position modification of the parts of the body support structure and where this body support structure does not optimally maintain the body parts in all positions .

La présente invention a pour objet un siège du type défini ci-dessus qui, tout en étant d'une structure très simple, assure un maintien optimal des parties du corps, dans toutes les positions pouvant être occupées par le siège.The present invention relates to a seat of the type defined above which, while being of a very simple structure, ensures optimal maintenance of the parts of the body, in all the positions that can be occupied by the seat.

Sur le siège conforme à l'invention, l'assise est divisée en une partie avant d'assise articulée sur le châssis et en une partie arrière d'assise articulée entre la partie avant d'assise et le dossier. La console est articulée sur le châssis en avant de l'articulation entre la partie arrière et la partie avant d'assise. La partie d'assise est reliée par une liaison non rigide à la console de soutien.On the seat according to the invention, the seat is divided into a front seat part articulated on the frame and a rear seat part articulated between the front seat part and the backrest. The console is articulated on the chassis in front of the articulation between the rear part and the front seat part. The seat part is connected by a non-rigid link to the support console.

Grâce à cet agencement, la structure de soutien du corps, formée de trois parties reliées entre elles de façon articulée, est suspendue en deux points sur châssis par la partie avant d'assise et sur la console par le dossier, de sorte que les trois parties procurent au corps un soutien optimal dans toutes les positions du siège.Thanks to this arrangement, the support structure of the body, formed of three parts linked together in an articulated manner, is suspended at two points on the chassis by the front seat part and on the console by the backrest, so that the three parts provide the body with optimal support in all seat positions.

De préférence, l'articulation entre la partie avant et la partie arrière d'assise comporte une butée limitant le débattement desdites deux parties vers le haut autour de cette articulation.Preferably, the articulation between the front part and the rear seat part comprises a stop limiting the movement of said two parts upwards around this articulation.

Suivant une autre caractéristique avantageuse de l'invention, le châssis comporte une butée, de préférence réglable, limitant le débattement vers le bas et vers l'arrière de la partie avant d'assise autour de l'axe d'articulation de cette partie sur le châssis.According to another advantageous characteristic of the invention, the chassis comprises a stop, preferably adjustable, limiting the downward and rearward movement of the front seat part around the axis of articulation of this part on the chassis.

La liaison non rigide entre la partie arrière d'assise et la console de soutien du dossier peut être avantageusement constituée par un élément élastique tel qu'un ressort.The non-rigid connection between the rear seat part and the backrest support console can advantageously consist of an elastic element such as a spring.

De préférence, le siège conforme à l'invention est équipé d'un dispositif de maintien en position et de rappel qui se trouve armé lors du passage de la structure de soutien du corps d'une position avancée à une position reculée et qui ramène automatiquement la structure de soutien du corps à la position avancée. Ce dispositif qui peut comprendre en parallèle un vérin à gaz, blocable en position, et un ressort mécanique de préférence réglable, agit sur la console, de préférence non pas directement, mais par l'intermédiaire d'un levier à deux bras articulé sur le châssis.Preferably, the seat according to the invention is equipped with a position-holding and return device which is armed when the body support structure passes from an advanced position to a retracted position and which automatically returns the supporting structure of the body in the advanced position. This device which may include in parallel a gas cylinder, lockable in position, and a preferably adjustable mechanical spring, acts on the console, preferably not directly, but by means of a lever with two arms articulated on the frame.

Le siège conforme à l'invention peut également être équipé d'une têtière articulée sur l'extrémité supérieure du dossier, cette tétière étant commandée en position conjointement avecla structure de soutien de corps de manière à pivoter vers l'avant lorsque la structure de soutien de corps passe d'une position avancée à une position reculée, et inversement. De préférence, la tétière est commandée par un câble flexible relié, avantageusement de façon réglable, au levier à deux bras par lequel le dispositif de maintien en position et de rappel agit sur la console de soutien du dossier.The seat according to the invention can also be equipped with a headrest articulated on the upper end of the backrest, this headrest being controlled in position jointly with the body support structure so as to pivot forwards when the support structure body moves from an advanced position to a retracted position, and vice versa. Preferably, the headrest is controlled by a flexible cable connected, advantageously in an adjustable manner, to the lever with two arms by which the device for holding in position and for restoring acts on the support console of the backrest.

En se référant aux dessins annexés, on va décrire ci-après plus en détail un mode de réalisation illustratif et non limitatif de l'objet de l'invention; sur les dessins :

  • la figure 1 est une vue schématique en élévation latérale d'un siège conforme à l'invention, en position avancée (position de travail);
  • la figure 2 est une vue correspondant à celle de la figure 1 montrant le même siège en position reculée (position de repos ou détente);
  • la figure 3 représente, à plus grande échelle, l'articulation entre la partie avant et la partie arrière d'assise et les deux butées de limitation de débattement des parties d'assise.
Referring to the accompanying drawings, there will be described below in more detail an illustrative and nonlimiting embodiment of the subject of the invention; on the drawings:
  • Figure 1 is a schematic side elevational view of a seat according to the invention, in the advanced position (working position);
  • Figure 2 is a view corresponding to that of Figure 1 showing the same seat in the retracted position (rest or relaxation position);
  • FIG. 3 represents, on a larger scale, the articulation between the front part and the rear seat part and the two stops for limiting the movement of the seat parts.

Selon la figure 1, un siège réglable, par exemple un siège de travail, comprend une structure 1 de soutien du corps, formé d'une partie avant d'assise 2, d'une partie arrière d'assise 3 et d'un dossier 4. La structure 1 de soutien du corps est montée sur un châssis 5 lui-même supporté, de préférence de façon réglable en hauteur, sur un pied 6 qui peut être par exemple muni de roulettes 7.According to FIG. 1, an adjustable seat, for example a work seat, comprises a structure 1 for supporting the body, formed of a front part seat 2, a rear seat part 3 and a backrest 4. The structure 1 for supporting the body is mounted on a frame 5 itself supported, preferably in adjustable height, on a foot 6 which can for example be provided with rollers 7.

La partie avant d'assise 2 est articulée par un axe 8 horizontal transversal, au voisinage de son extrémité avant, sur l'extrémité avant du châssis 5.The front seat part 2 is articulated by a transverse horizontal axis 8, in the vicinity of its front end, on the front end of the chassis 5.

Le dossier 4 est articulé à faible distance au-dessus de son extrémité inférieure, par un axe 9 horizontal transversal sur une extrémité d'une console 10 sensiblement en coude à 90°, arrondi, dont l'autre extrémité est articulée par un axe 11 horizontal transversal sur le châssis 5 en avant de la liaison de ce châssis 5 avec le pied 6.The backrest 4 is articulated at a short distance above its lower end, by a horizontal transverse axis 9 on one end of a console 10 substantially at 90 ° bend, rounded, the other end of which is articulated by an axis 11 horizontal transverse on the chassis 5 in front of the connection of this chassis 5 with the foot 6.

La partie arrière d'assise 3 est articulée à son extrémité avant par un axe horizontal transversal 12 sur l'extrémité arrière de la partie avant d'assise 2 et à son extrémité supérieure par un axe horizontal transversal 13 sur l'extrémité inférieure du dossier 4. L'axe d'articulation 12 se trouve situé en arrière de l'axe d'articulation 11 de la console 10 sur le châssis 5. La partie arrière d'assise 3 présente, pratiquement sur toute sa longueur, une forme incurvée sensiblement en coude à 90° et se raccorde sensiblement sous forme de tangente à la partie avant d'assise 2 et au dossier 4.The rear seat part 3 is articulated at its front end by a horizontal transverse axis 12 on the rear end of the front seat part 2 and at its upper end by a horizontal transverse axis 13 on the lower end of the backrest 4. The hinge pin 12 is located behind the hinge pin 11 of the console 10 on the chassis 5. The rear seat part 3 has, practically over its entire length, a substantially curved shape. at a 90 ° bend and connects substantially in the form of a tangent to the front seat part 2 and the backrest 4.

Un élément de liaison 14 non rigide, de préférence un élément élastique tel qu'un ressort mécanique ou autre (par exemple un silent-bloc) relie l'élément arrière d'assise 3 de façon souple à la console 10 entre les deux axes d'articulation 12 et 13.A non-rigid connecting element 14, preferably an elastic element such as a mechanical spring or the like (for example a silent block) connects the rear seat element 3 flexibly to the console 10 between the two axes d hinge 12 and 13.

Un dispositif 15 de maintien en position et de rappel comprenant de préférence un vérin pneumatique blocable en position et, en parallèle avec ce vérin, un ressort mécanique de préférence réglable en tension, est prévu entre le châssis 5 et la console 10. Le dispositif 15 est articulé à une extrémité par un axe horizontal transversal 16 sur le châssis 5, au voisinage de l'extrémité avant du châssis 5, et à son autre extrémité par un axe horizontal transversal 17 sur une extrémité d'υn levier 18 à deux bras qui est articulé par un axe 19 horizontal transversal sur le châssis 5 et dont l'autre extrémité est articulée par un axe horizontal transversal 20 sur la console 10, de préférence dans une lumière 21 de cette dernière.A device 15 for holding in position and for restoring preferably comprising a pneumatic cylinder lockable in position and, in parallel with this cylinder, a mechanical spring preferably adjustable in tension, is provided between the chassis 5 and the console 10. The device 15 is articulated at one end by a transverse horizontal axis 16 on the chassis 5, in the vicinity of the front end of the chassis 5, and at its other end by a transverse horizontal axis 17 on one end of a lever 18 with two arms which is articulated by a transverse horizontal axis 19 on the frame 5 and the other end of which is articulated by a transverse horizontal axis 20 on the console 10, preferably in a slot 21 in the latter.

Le siège illustré par la figure 1 comprend, en outre, une tétière 22 articulée par un axe horizontal transversal 23 sur l'extrémité supérieure du dossier 4. La tétière 22 est commandée en position par un câble flexible 24 sous une gaine, le câble 24 étant relié à l'axe 17 du levier 18 actionné par le dispositif 15. La gaine non représentée du câble 24 prend appui sur le châssis 5 par l'intermédiaire d'un dispositif de réglage 25 permettant un réglage de la longueur de la gaine entre ces deux points d'appui, donc un réglage de la tension du câble 24.The seat illustrated in FIG. 1 further comprises a headrest 22 articulated by a horizontal transverse axis 23 on the upper end of the backrest 4. The headrest 22 is controlled in position by a flexible cable 24 under a sheath, the cable 24 being connected to the axis 17 of the lever 18 actuated by the device 15. The sheath, not shown, of the cable 24 bears on the frame 5 by means of an adjustment device 25 allowing an adjustment of the length of the sheath between these two support points, therefore an adjustment of the tension of the cable 24.

Comme le montre la figure 1 et, de façon plus détaillée, la figure 3, le châssis 5 porte une butée 26 réglable pour la partie avant d'assise 2. La butée 26 constituée par une vis engagée dans un trou taraudé du châssis 5 et bloquée en position à l'aide d'un contre-écrou est disposée en arrière de l'axe 8 mais en avant de l'axe 12. La butée 26 limite le débattement angulaire vers le bas et vers l'arrière de la partie avant d'assise 2 en position reculée du siège (figure 2).As shown in FIG. 1 and, in more detail, in FIG. 3, the chassis 5 carries an adjustable stop 26 for the front seat part 2. The stop 26 constituted by a screw engaged in a threaded hole in the chassis 5 and locked in position using a lock nut is disposed behind the axis 8 but in front of the axis 12. The stop 26 limits the angular movement downwards and rearwards of the front part seat 2 in the retracted position of the seat (Figure 2).

On reconnaît par ailleurs sur la figure 3 que l'articulation entre les deux parties d'assise 2 et 3 (axe d'articulation 12) comporte deux pièces de butée 27 et 28 sur lesdites deux parties 2 et 3, les deux pièces 27 et 28 venant buter l'une contre l'autre, au-dessus de l'axe d'articulation 12, lorsque le siège est en position avancée (figure 1) pour limiter, dans cette position, le débattement vers le bas des deux parties 2 et 3 autour de l'axe 12 et donner aux deux parties 2 et 3 une légère inclinaison vers le bas et vers l'avant.It is also recognized in FIG. 3 that the articulation between the two seat parts 2 and 3 (articulation axis 12) comprises two abutment parts 27 and 28 on said two parts 2 and 3, the two parts 27 and 28 abutting against each other, above the hinge pin 12, when the seat is in the advanced position (Figure 1) to limit, in this position, the downward movement of the two parts 2 and 3 around the axis 12 and give the two parts 2 and 3 a slight downward and forward tilt.

La structure 1 de soutien du corps forme donc un ensemble de trois parties 2, 3, 4 articulées, suspendu en deux points 8 et 9 et maintenu, au niveau de la partie médiane 3 par une liaison souple et déformable 14.The body support structure 1 therefore forms a set of three articulated parts 2, 3, 4, suspended at two points 8 and 9 and held, at the level of the middle part 3 by a flexible and deformable connection 14.

Dans la position avancée (figure 1), la partie avant d'assise 2 sensiblement plane adopte une position légèrement inclinée vers l'avant et vers le bas par rapport à l'horizontale, de sorte que cette partie 2 qui soutient les cuisses de l'utilisateur ne perturbe pas l'appui au sol des pieds de l'utilisateur et ne risque pas de bloquer la circulation sanguine au-dessus des genoux.In the advanced position (Figure 1), the substantially flat front seat part 2 adopts a position slightly inclined forward and downward relative to the horizontal, so that this part 2 which supports the thighs of the he user does not disturb the support on the ground of the feet of the user and does not risk blocking the blood circulation above the knees.

Lors du passage de la position avancée selon la figure 1 à la position reculée selon la figure 2, qui se fait, après déblocage du dispositif 15, sous la pression exercée vers l'arrière sur le dossier 4 par l'utilisateur, la console 10 pivote vers le bas autour de son axe d'articulation 11, ce qui provoque d'abord un pivotement vers le bas de l'ensemble de la structure de soutien de corps 1 autour de l'axe 8 et, après l'entrée en contact de la partie avant d'assise 2 avec la butée 26, un transfert du mouvement de pivotement sur l'axe 9, c'est-à-dire un pivotement du haut du dossier 4 vers l'arrière autour de l'axe 9 et, en même temps, un pivotement vers le haut et l'avant de la partie arrière d'assise 3 autour de l'axe 12. L'articulation du dossier 4 sur la console et sur la partie arrière d'assise 3 est telle que la partie du dossier 4 située en dessous de l'axe 9 décrive, lors du changement de position, une trajectoire telle qu'elle soutienne efficacement les reins de l'utilisateur dans toutes les positions du siège. Il y a lieu de noter que dans sa position en appui sur la butée 26, la partie avant d'assise 2 se trouve légèrement inclinée vers l'arrière et vers le bas de manière à éviter le glissement vers l'avant du corps, en position reculée du siège.During the passage from the advanced position according to FIG. 1 to the retracted position according to FIG. 2, which is done, after unlocking of the device 15, under the pressure exerted backwards on the backrest 4 by the user, the console 10 pivots down around its hinge axis 11, which first causes the entire body support structure 1 to pivot downward around the axis 8 and, after the front seat part 2 comes into contact with the stopper 26, a transfer of the pivoting movement on the axis 9, that is to say a pivoting from the top of the back 4 towards the rear around the axis 9 and, at the same time, a pivoting upwards and forwards of the rear seat part 3 around the axis 12. The articulation of the backrest 4 on the console and on the rear seat part 3 is such that the part of the backrest 4 located below the axis 9 describes, when changing position, a path such that it effectively supports the kidneys of the user in all positions of the seat. It should be noted that in its position in abutment on the stop 26, the front seat part 2 is slightly inclined backwards and downwards so as to avoid sliding the body forward, in back seat position.

La têtière 22 pivote en opposition au dossier 4 sur lequel elle est articulée, c'est-à-dire qu'elle avance lors du recul de ce dernier, pour occuper, en position reculée du siège, une position davantage inclinée vers l'avant qu'en position avancée du siège. C'est dans la position reculée du siège qui correspond à la position de détente ou de repos que la tétière est la plus utilisée.The headrest 22 pivots in opposition to the backrest 4 on which it is articulated, that is to say it advances when the latter recedes, in order to occupy, in the retracted position of the seat, a position more inclined towards the front only in the advanced position of the seat It is in the retracted position of the seat which corresponds to the position of relaxation or rest that the headrest is most used.

Par un réglage du ressort prévu dans le dispositif 15 de maintien en position et de rappel, il est possible de régler l'équilibre entre les deux couples agissant sur le levier 18, d'une part en fonction du poids de l'utilisateur et d'autre part en fonction de la force de rappel du dispositif 15.By adjusting the spring provided in the device 15 for holding in position and returning, it is possible to adjust the balance between the two couples acting on the lever 18, on the one hand according to the weight of the user and d on the other hand depending on the return force of the device 15.
