La présente invention concerne les sièges de repos ou de relaxation du type comprenant un piètement, une assise articulée sur ce piétement autour d'un premier axe, un dossier articulé sur l'assise autour d'un deuxième axe parallèle au premier, et un repose-jambes également articulé sur l'assise autour d'au moins un axe parallèle aux deux autres, des moyens d'actionnement étant prévus pour pouvoir régler de façon indépendante la position de l'assise, du dossier et du repose-jambes.The present invention relates to rest or relaxation seats of the type comprising a base, a seat articulated on this base around a first axis, a file articulated on the seat around a second axis parallel to the first, and a rest legs also articulated on the seat around at least one axis parallel to the other two, actuation means being provided in order to be able to independently adjust the position of the seat, the backrest and the legrest.

Un siège correspondant à cette définition est décrit dans le brevet FR-A-2 392 629. Cependant, dans cet agencement connu, le dispositif d'actionnement comprend trois vérins électriques assurant chacun le déplacement et le positionnement de l'un des trois éléments mobiles. La présence de trois vérins électriques entraine une certaine complexité et un coût élevé de fabrication, ce qui constitue un inconvénient très important.A seat corresponding to this definition is described in patent FR-A-2 392 629. However, in this known arrangement, the actuation device comprises three electric jacks each ensuring the displacement and the positioning of one of the three mobile elements . The presence of three electric cylinders leads to a certain complexity and a high manufacturing cost, which constitutes a very significant drawback.

On connait également (FR-2 470 563) un siège comprenant également un piétement, une assise, un dossier et un repose-jambes, mais dans lequel les déplacements et les réglages des trois éléments mobiles ne sont pas effectués de façon indépendante. De tels sièges présentent l'inconvénient de ne procurer que des possibilités de réglage limitées puisqu'à chaque position déterminée de l'un des éléments correspond une position déterminée d'au moins l'un des deux autres éléments mobiles.There is also known (FR-2,470,563) a seat also comprising a base, a seat, a backrest and a legrest, but in which the movements and adjustments of the three mobile elements are not carried out independently. Such seats have the drawback of providing only limited adjustment possibilities since each determined position of one of the elements corresponds to a determined position of at least one of the two other mobile elements.

Le but de cette invention est par conséquent de fournir un siège du type précité, qui soit de construction relativement économique, et d'un emploi particulièrement commode, tout en étant résistant et fiable.The object of this invention is therefore to provide a seat of the aforementioned type, which is of relatively economical construction, and of particularly convenient use, while being resistant and reliable.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • - les Fig.1 et 2 sont deux vues en coupe d'un siège selon l'invention, représentant ce siège dans deux positions différentes;
  • - la Fig.3 est une vue de détail représentant une variante du dispositif de rappel entre le dossier et l'assise;
  • - la Fig. 4 est une vue schématique en perspective, d'un sous-ensemble complet, selon une variante de réalisation; et
  • - la Fig. 5 est une vue en perspective d'une partie du mécanisme de commande de la Figure 4.
The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which:
  • - Fig.1 and 2 are two sectional views of a seat according to the invention, representing this seat in two different positions;
  • - Fig.3 is a detail view showing a variant of the return device between the backrest and the seat;
  • - Fig. 4 is a schematic perspective view of a complete sub-assembly, according to an alternative embodiment; and
  • - Fig. 5 is a perspective view of part of the control mechanism of FIG. 4.

On voit sur les Fig.1 et 2, un siège suivant l'invention comprenant comme parties essentielles un piétement P, une assise A, un dossier D et un repose-jambes R.We see in Fig. 1 and 2, a next seat the invention comprising as essential parts a base P, a seat A, a backrest D and a leg rest R.

Le piétement comprend de façon classique un bâti schématisé par l'un de ses éléments 10, deux accoudoirs 11 et des éléments de garnissage. Ce bâti ne sera pas décrit en détail et il sera simplement fait référence dans le corps de la description à certains éléments qui jouent un rôle particulier dans l'invention.The base conventionally comprises a frame shown schematically by one of its elements 10, two armrests 11 and trim elements. This frame will not be described in detail and reference will simply be made in the body of the description to certain elements which play a particular role in the invention.

L'assise comprend également un bâti 20a, 20b qui peut être de construction traditionnelle et qui est articulé au voisinage de sa partie arrière sur une ferrure 12 du bâti 10, de façon à pouvoir basculer autour d'un axe X-X par rapport au piètement.The seat also includes a frame 20a, 20b which can be of traditional construction and which is articulated in the vicinity of its rear part on a fitting 12 of the frame 10, so as to be able to tilt around an axis X-X relative to the base.

A l'exception de certains composants qui sont disposés dans la partie médiane du siège, ce qui sera précisé par la suite, il est bien entendu que des moyens identiques sont disposés de chaque côté du siège, pour assurer l'articulation de l'assise sur le piétement et du repose-jambes sur l'assise, par exemple.With the exception of certain components which are arranged in the middle part of the seat, which will be explained below, it is understood that identical means are arranged on each side of the seat, to ensure the articulation of the seat. on the base and the legrest on the seat, for example.

Dans une partie intermédiaire avant de l'assise, cette dernière porte des ferrures 21 munies de lumières 22 de forme allongée dans lesquelles sont reçus des doigts 23 portés par des ferrures 13 elles- mêmes solidaires du piétement. Sur chaque doigt, est monté un ressort du type rondelle Belleville et un écrou à papillon 24 permettant de serrer plus ou moins ce ressort. Un tel mécanisme complété par des rondelles de friction constitue un moyen de freinage entre l'assise et le piétement, lors des mouvements de basculement de l'assise autour de l'axe X-X. L'amplitude de ce basculement est limitée par la longueur des lumières 22.In an intermediate front part of the seat, the latter carries fittings 21 provided with lights 22 of elongated shape in which are received fingers 23 carried by fittings 13 themselves integral with the base. On each finger, there is mounted a spring of the Belleville washer type and a butterfly nut 24 making it possible to tighten this spring more or less. Such a mechanism completed by friction washers constitutes a braking means between the seat and the base, during tilting movements of the seat around the axis XX. The amplitude of this tilting is limited by the length of lights 22.

Le dossier D est articulé sur l'assise, à la partie arrière de cette dernière, par exemple entre des ferrures 25, le dossier étant monté basculant autour d'un axe Y-Y parallèle à l'axe X-X. Le basculement du dossier vers l'avant est limité par une butée constituée par l'extrémité d'une ferrure coudée 31 venant en appui contre une partie repliée 25a de la ferrure 25.The backrest D is articulated on the seat, at the rear part of the latter, for example between fittings 25, the backrest being mounted tilting about an axis Y-Y parallel to the axis X-X. The tilting of the backrest towards the front is limited by a stop constituted by the end of a bent fitting 31 coming to bear against a folded part 25a of the fitting 25.

Il est prévu de plus entre la partie inférieure du dossier et la partie arrière de l'assise, un dispositif de rappel, qui peut être unique et disposé dans la partie centrale du siège, ce dispositif comprenant dans le mode de réalisation des Fig.1 et 2, un ressort hélicoidal 32 travaillant en compression, et disposé entre deux surfaces d'appui 33, 34. La première surface d'appui 33 est délimitée par une pièce montée autour d'un axe 35 sur l'assise. La deuxième surface d'appui est constituée par une plaque formant écrou et vissée sur une tige filetée 36, elle-même montée sur le bâti du dossier de façon à pouvoir osciller autour d'un axe 37. On voit que la position de la plaque 34 le long de la tige 36 peut être modifiée en vissant ou en dévissant cette plaque, ce qui permet de modifier les caractéristiques et la course du ressort 32.There is also provided between the lower part of the backrest and the rear part of the seat, a return device, which can be unique and arranged in the central part of the seat, this device comprising in the embodiment of Fig.1 and 2, a helical spring 32 working in compression, and disposed between two bearing surfaces 33, 34. The first bearing surface 33 is delimited by a part mounted around an axis 35 on the seat. The second bearing surface is constituted by a plate forming a nut and screwed onto a threaded rod 36, itself mounted on the backrest frame so as to be able to oscillate around an axis 37. It can be seen that the position of the plate 34 along the rod 36 can be modified by screwing or unscrewing this plate, which makes it possible to modify the characteristics and the stroke of the spring 32.

Le repose-jambes R est articulé sur la partie avant de l'assise, par l'intermédiaire d'une tringlerie d'articulation 40 du type à ciseaux comprenant deux leviers 41, 42 articulés entre eux en 43 et dont l'un 41 est articulé sur le bâti de l'assise autour d'un axe 44, tandis que l'autre est articulé en 45 sur le repose-jambes. Le premier de ces leviers a une forme coudée, de façon à pouvoir délimiter une partie 41a en retrait par rapport aux axes d'articulation 43, 44, et pouvoir recevoir dans cette partie en retrait la traverse 20a faisant partie de l'assise. La tringlerie d'articulation du repose-jambes sur l'assise est complétée par un premier levier 46 articulé, d'une part, en 46A sur l'assise et, d'autre part, en 47 sur la deuxième extrémité du levier 42, et par une biellette 48 articulée entre le repose-jambes (en 49) et la deuxième extrémité du levier 41, en 50.The legrest R is articulated on the front part of the seat, by means of an articulation linkage 40 of the scissor type comprising two levers 41, 42 articulated together at 43 and one of which 41 is articulated on the seat frame around an axis 44, while the other is articulated at 45 on the legrest. The first of these levers has an angled shape, so that it can delimit a part 41a set back relative to the hinge pins 43, 44, and be able to receive in this set back part the crosspiece 20a forming part of the seat. The articulation linkage of the legrest on the seat is completed by a first lever 46 articulated, on the one hand, at 46A on the seat and, on the other hand, at 47 on the second end of the lever 42, and by a link 48 articulated between the legrest (at 49) and the second end of the lever 41, at 50.

Le dispositif d'actionnement du repose-jambes est disposé à peu près dans l'axe du siège et comprend un vérin pneumatique 51 comprenant un corps 52 et une tige de piston 53. Dans l'exemple représenté, le corps est articulé sur une ferrure 54, elle-même solidaire d'une traverse (non visible sur le dessin) reliant les deux leviers 46 des tringleries d'articulation du repose-jambes. La tige 53 du vérin est quant à elle fixée sur une traverse 55 articulée autour d'un axe transversal entre deux plaques 56 solidaires du bâti de l'assise. Ce vérin pneumatique peut être commandé par des moyens à commande manuelle comprenant une charnière 57 dont l'une des branches 57a est fixée sur la traverse 55 et dont l'autre branche 57g est accrochée sur l'extrémité d'un câble Bowden 58, dont l'autre extrémité est reliée à une manette de manoeuvre 59. La branche mobile 57b agit sur un doigt de commande 60 qui fait saillie à l'extrémité de la tige 53. Un tel vérin pneumatique est connu dans la technique et ne nécessite pas de description plus approfondie.The leg rest actuation device is disposed roughly in the axis of the seat and comprises a pneumatic cylinder 51 comprising a body 52 and a piston rod 53. In the example shown, the body is articulated on a fitting 54, itself secured to a crosspiece (not visible in the drawing) connecting the two levers 46 of the articulation linkages of the legrest. The rod 53 of the jack is in turn fixed to a cross member 55 articulated around a transverse axis between two plates 56 integral with the seat frame. This pneumatic cylinder can be controlled by manual control means comprising a hinge 57 one of the branches 57a of which is fixed to the cross-member 55 and the other branch of which 57g is hung on the end of a Bowden cable 58, of which the other end is connected to an operating lever 59. The movable branch 57b acts on a control finger 60 which projects at the end of the rod 53. Such a pneumatic cylinder is known in the art and does not require any further description.

Le fonctionnement d'un tel siège, qui peut bien entendu être à une ou plusieurs places, découle directement de la description qui vient d'être faite. On notera cependant que la position de chacun des trois éléments mobiles : assise, dossier, repose-jambes, peut être réglée indépendamment des autres, et ce de façon particulièrement simple. L'utilisateur peut, par simple appui sur la partie avant ou la partie arrière de l'assise, faire basculer cette dernière dans un sens ou dans l'autre autour de l'axe X-X, ce mouvement de basculement 'étant contrôlé par le mécanisme de freinage 21-24 interposé entre l'assise et le piétement. Ce mécanisme de freinage est réglé, en serrant plus ou moins l'écrou 24, de façon à équilibrer le poids du corps de l'utilisateur, de sorte que celui-ci est maintenu dans la position d'assise qu'il a choisi.The operation of such a seat, which can of course be in one or more places, follows directly from the description which has just been made. Note, however, that the position of each of the three mobile elements: seat, backrest, legrest, can be adjusted independently of the others, and this in a particularly simple way. The user can, by simply pressing the front part or the rear part of the seat, tilt the latter in one direction or the other around the axis XX, this tilting movement being controlled by the mechanism 21-24 braking interposed between the seat and the base. This braking mechanism is adjusted, by tightening more or less the nut 24, so as to balance the weight of the user's body, so that the latter is kept in the sitting position he has chosen.

De même, le réglage de la position d'inclinaison du dossier s'effectue très simplement, l'utilisateur prenant appui sur les accoudoirs et repoussant le dossier pour le faire basculer en position plus inclinée. Ce déplacement s'effectue en comprimant le ressort 32 dont le réglage est également choisi pour équilibrer le poids du corps de l'utilisateur, en utilisation statique. Lorsque l'utilisateur quitte le siège, le dossier est ramené en position avant sous l'effet de la force du ressort 32.Similarly, the adjustment of the position of the backrest is very simple, the user pressing on the armrests and pushing the backrest to tilt it into a more inclined position. This movement is carried out by compressing the spring 32, the adjustment of which is also chosen to balance the weight of the user's body, in static use. When the user leaves the seat, the backrest is brought back to the front position under the effect of the force of the spring 32.

Le repose-jambes peut occuper l'une quelconque des positions comprises entre la position repliée représentée à la Fig.1 et la position extrême représentée à la Fig.2. Ces changements de position sont commandés par l'utilisateur à partir de la manette 59, par action du vérin pneumatique 51. Il est à noter que compte tenu de la forme du levier 41 faisant partie du mécanisme d'articulation du repose-jambes sur l'assise, ce repose-jambes peut prendre une position haute dans laquelle il se trouve au moins dans le prolongement de l'assise, ce qui permet à l'utilisateur d'adopter une position surélevée des jambes, particulièrement favorable et confortable.The legrest can occupy any of the positions between the folded position shown in Fig.1 and the extreme position shown in Fig.2. These position changes are controlled by the user from the lever 59, by the action of the pneumatic cylinder 51. It should be noted that taking into account the shape of the lever 41 forming part of the articulation mechanism of the legrest on the seat, this legrest can take a high position in which it is at least in the extension of the seat, which allows the user to adopt an elevated position of the legs, particularly favorable and comfortable.

Dans la variante représentée à la Fig.3, le dossier est articulé sur l'assise autour d'un axe Y-Y et comporte un levier coudé 61 également articulé autour de l'axe Y-Y et relié par son autre extrémité à l'assise par un compas ou une genouillère 62. Ce compas comprend deux branches 62a, 62b constituées chacune par une biellette. Ces deux biellettes sont articulées entre elles autour d'un axe 63 et articulées à leurs autres extrémités, respectivement en 64, sur l'assise et en 65 sur le levier 61. Un ressort de traction 66 est interposé entre une zône du levier coudé proche de l'axe Y-Y, et l'une des deux branches du compas où même l'articulation entre ces deux branches. Comme précédemment, la caractéristique de ce ressort, qui fonctionne ici en traction, peut être réglée par un dispositif connu 67 du type à vis et écrou. Le fonctionnement est exactement celui décrit ci-dessus, à l'exception du fait que le ressort de rappel fonctionne en traction au lieu de fonctionner en compression.In the variant shown in FIG. 3, the backrest is articulated on the seat around an axis YY and comprises an angled lever 61 also articulated around the axis YY and connected by its other end to the seat by a compass or a kneepad 62. This compass comprises two branches 62a, 62b each constituted by a link. These two links are articulated together around an axis 63 and articulated at their other ends, respectively at 64, on the seat and at 65 on the lever 61. A tension spring 66 is interposed between a zone of the close bent lever of the YY axis, and one of the two branches of the compass where even the articulation between these two branches. As before, the characteristic of this spring, which operates here in tension, can be adjusted by a known device 67 of the screw and nut type. Operation is exactly as described above, except that the return spring operates in tension instead of operating in compression.

Les avantages d'un tel siège sont les suivants :

  • - les trois mouvements de réglage possibles sont indépendants les uns des autres, ce qui permet à l'utilisateur de varier à l'infini la position de chacun de ces éléments, dans les limites bien entendu des débattements de chacun d'eux;
  • - les réglages de l'assise et du dossier ne sont pas obtenus au moyen de dispositifs d'actionnement compliqués tels que vérins électriques ou analogues, mais par un mécanisme de freinage dans un cas et par un ressort d'équilibrage et de rappel dans l'autre. Le fait que ces deux mécanismes soient réglables permet d'adapter le siège à des utilisateurs différents.
  • - les moyens mis en jeu sont simples, solides et fiables;
  • - le dispositif d'actionnement utilisé pour le repose-jambes est particulièrement efficace et assure en particulier le maintien positif de ce repose-jambes pour toutes les positions;
  • - le mécanisme d'articulation du repose-jambes sur l'assise est tel que ce repose-jambes peut occuper une position très haute, particulièrement favorable pour le confort de l'utilisateur.
The advantages of such a seat are as follows:
  • - The three possible adjustment movements are independent of each other, which allows the user to vary infinitely the position of each of these elements, within the limits of course of the deflections of each of them;
  • the seat and backrest adjustments are not obtained by means of complicated actuating devices such as electric jacks or the like, but by a braking mechanism in one case and by a balancing and return spring in the other. The fact that these two mechanisms are adjustable makes it possible to adapt the seat to different users.
  • - the means involved are simple, solid and reliable;
  • - The actuation device used for the legrest is particularly effective and ensures in particular the positive maintenance of this legrest for all positions;
  • - The articulation mechanism of the legrest on the seat is such that this legrest can occupy a very high position, particularly favorable for the comfort of the user.

On a représenté à la Figure 4 un sous-ensemble complet comprenant les divers mécanismes d'actionnement et de blocage ainsi que leurs moyens de commande, qui constituent une variante de certains des moyens représentés aux Figures 1 à 3.FIG. 4 shows a complete sub-assembly comprising the various actuation and blocking mechanisms as well as their control means, which constitute a variant of some of the means represented in FIGS. 1 to 3.

Les éléments correspondants de ce mode de réalisation sont désignés sur cette Figure 4 par les mêmes numéros de référence que sur les Figures 1 et 2, augmentés de 100.The corresponding elements of this embodiment are designated in this Figure 4 by the same reference numbers as in Figures 1 and 2, increased by 100.

On voit sur la Figure 4 un cadre métallique constitué par deux plaques 120jz reliées par des traverses 155 et 174. Le mécanisme de commande de la position angulaire du dossier comprend un vérin pneumatique 171 analogue au vérin 51 décrit à propos des Figures 1 et 2. Le corps 172 de ce vérin est articulé à la partie inférieure du dossier, au-dessous de l'axe d'articulation de ce dossier sur l'assise et la tige 173 du vérin est fixée sur la traverse 174 elle-même articulée entre deux plaques 175 solidaires des plaques 120b. Ce vérin est commandé par un mécanisme à charnière 176 et câble d'actionnement 177, comme le vérin 151 et le vérin 51 du premier mode de réalisation. Il est à noter que le vérin 171 est disposé sous l'assise, à peu près parallèlement à cette dernière, et ne peut donc constituer aucune gêne pour l'occupant du siège.FIG. 4 shows a metal frame constituted by two 120jz plates connected by crosspieces 155 and 174. The mechanism for controlling the angular position of the backrest comprises a pneumatic cylinder 171 similar to the cylinder 51 described with reference to Figures 1 and 2. The body 172 of this jack is articulated at the lower part of the backrest, below the hinge pin of this backrest on the seat and the rod 173 of the jack is fixed on the cross member 174 itself articulated between two 175 plates integral with the 120b plates. This cylinder is controlled by a mechanism with hinge 176 and actuation cable 177, like the jack 151 and the jack 51 of the first embodiment. It should be noted that the jack 171 is disposed under the seat, approximately parallel to the latter, and therefore cannot constitute any discomfort for the occupant of the seat.

Le repose-jambes est relié à l'assise par un mécanisme d'articulation 140 du type à ciseaux. Les deux leviers 141 qui sont articulés sur les plaques 120h autour d'axes 144, sont reliés par une traverse 141A sur laquelle est articulé et agit le vérin 151. Ce vérin 151 est actionné par un câble 158.The legrest is connected to the seat by a hinge mechanism 140 of the scissor type. The two levers 141 which are articulated on the plates 120h around axes 144, are connected by a cross-member 141A on which is articulated and acts the jack 151. This jack 151 is actuated by a cable 158.

Suivant une caractéristique particulièrement intéressante de ce mode de réalisation, les deux vérins 151 et 171 sont commandés à partir d'un même mécanisme de commande 180 représenté plus en détail à la Figure 5. Ce mécanisme comprend un support 181 destiné à être fixé sur le piètement du siège. Ce support comporte à sa partie inférieure deux ailes 182 sur lesquelles prennent apppui les gaines des câbles 158 et 177. Un organe de manoeuvre unique 183 formant levier est articulé à la partie supérieure du support 181. De part et d'autre de ce levier de manoeuvre 183 sont articulés sur le support deux leviers 184, 185 sur les extrémités inférieures 184a, 185a, desquels sont fixées les extrémités des câbles 158 et 177. De préférence, le levier 183 comporte à sa partie inférieure un rebord 183a destiné à améliorer la portée sur les leviers 184, 185. Dans sa partie centrale, le support 181 comporte une butée 186, obtenue par exemple par crevé, et contre laquelle les leviers 184, 185 viennent en appui, lorsqu'ils sont sollicités par leurs câbles respectifs 158, 176.According to a particularly advantageous characteristic of this embodiment, the two cylinders 151 and 171 are controlled from the same control mechanism 180 shown in more detail in FIG. 5. This mechanism comprises a support 181 intended to be fixed on the seat base. This support comprises at its lower part two wings 182 on which the sheaths of the cables 158 and 177 take support. A single operating member 183 forming a lever is articulated at the upper part of the support 181. On either side of this lever operation 183 are articulated on the support two levers 184, 185 on the lower ends 184a, 185a, which are fixed the ends of the cables 158 and 177. Preferably, the lever 183 has at its lower part a flange 183a intended to improve the range on the levers 184, 185. In its central part, the support 181 comprises a stop 186, obtained for example by a puncture, and against which the levers 184, 185 come to bear, when they are stressed by their respective cables 158, 176 .

Ce mode de réalisation offre pour l'essentiel les mêmes avantages que le précédent, auxquels s'ajoute celui de disposer d'un organe de manoeuvre unique 183 qui permet selon qu'il est manoeuvré dans un sens ou dans l'autre, d'agir sur l'un ou l'autre des deux vérins 151 et 171. L'utilisateur peut ainsi très facilement choisir la position qui lui convient pour le repose-pieds et pour le dossier. De plus, comme cela a déjà été indiqué, la position du vérin d'actionnement du dossier est particulièrement favorable puisque ce vérin ne peut constituer aucune gêne pour l'utilisateur et que le point d'application de la force de basculement du dossier est également particulièrement favorable.This embodiment provides for the essen tiel the same advantages as the previous one, to which is added that of having a single operating member 183 which allows depending on whether it is operated in one direction or the other, to act on one or the other of the two cylinders 151 and 171. The user can thus very easily choose the position which suits him for the footrest and for the backrest. In addition, as has already been indicated, the position of the actuator for the backrest is particularly favorable since this actuator cannot constitute any discomfort for the user and since the point of application of the tilting force of the backrest is also particularly favorable.

Bien entendu, le terme de siège utilisé dans ce mémoire n'est pas limitatif et vise tout siège proprement dit, fauteuil, canapé, etc. quels que soit son usage et son implantation.Of course, the term seat used in this specification is not limiting and refers to any seat itself, armchair, sofa, etc. whatever its use and location.
