Description

L'invention a pour objet un siège de repos susceptible d'occuper une pluralité de positions, depuis une position dans laquelle son dossier occupe une faible inclinaison assez proche de celle du dossier d'une chaise, jusqu'à une position de relaxation dans laquelle son dossier occupe une forte inclinaison se rapprochant de l'horizontale.The subject of the invention is a rest seat capable of occupying a plurality of positions, from a position in which its backrest occupies a slight inclination fairly close to that of the back of a chair, to a relaxation position in which its backrest occupies a steep inclination approaching the horizontal.

Des sièges de ce type sont connus en soi; et nombreux sont les mécanismes plus ou moins compliqués adoptés pour permettre leurs changements de positions. Quels que soient ces mécanismes, ces sièges présentent une caractéristique commune résidant dans la fixité de la surface servant d'assise, c'est-à-dire de siège proprement dit, seule étant réglagle la position du dossier. De cette fixité de l'assise, il résulte que le confort de l'ensemble du siège n'est véritablement bon que pour une ou certaines inclinaisons du dossier. C'est ainsi que, si la forme et la position de l'assise sont telles que la surface d'assise est sensiblement horizontale, le confort est bon lorsque le dossier occupe une position assez relevée, mais il devient mauvais lorsque le dossier est amené en position inclinée, le corps de l'utilisateur tendant, en effet, à glisser vers l'avant car il n'est pas retenu par la surface d'assise. Inversement, si la surface d'assise occupe une position fixe quelque peu inclinée, le confort du siège est bon lorsque le dossier est fortement incliné, mais est mauvais lorsque le dossier est redressé.Seats of this type are known per se; and many are the more or less complicated mechanisms adopted to allow them to change positions. Whatever these mechanisms are, these seats have a common characteristic residing in the fixity of the surface serving as a seat, that is to say of the seat itself, only the position of the backrest being adjustable. From this fixedness of the seat, it follows that the comfort of the entire seat is only really good for one or certain inclinations of the backrest. Thus, if the shape and position of the seat are such that the seat surface is substantially horizontal, comfort is good when the backrest occupies a fairly raised position, but it becomes poor when the backrest is brought in the inclined position, the body of the user tending, in fact, to slide forward because it is not retained by the seat surface. Conversely, if the seat surface occupies a somewhat inclined fixed position, the comfort of the seat is good when the backrest is strongly inclined, but is poor when the backrest is straightened.

Il y a là une lacune que l'invention palie. Elle a pour objet, à cet effet, un siège dans lequel, l'assise étant articulée sur les pieds avant, le dossier étant articulé sur l'assise, et les accoudoirs étant articulés sur le dossier, ce dernier est articulé sur les pieds arrière par un axe traversant une glissière aménagée dans chacun des deux pieds arrière, et les deux accoudoirs sont reliés au sommet des pieds avant par un système d'encliquetage à plusieurs positions, avec leuquel il est possible de modifier l'inclinaison du dossier dont le changement d'inclinaison entraîne, par déplacement de l'axe dans la glissière une modification de l'inclinaison de l'assise.There is a gap there that the invention overcomes. It has for its object, for this purpose, a seat in which, the seat being articulated on the front feet, the backrest being articulated on the seat, and the armrests being articulated on the backrest, the latter is articulated on the rear feet by an axis crossing a slide arranged in each of the two rear legs, and the two armrests are connected to the top of the front legs by a latching system with several positions, with leuquel it is possible to modify the inclination of the backrest whose change inclination causes, by displacement of the axis in the slide a modification of the inclination of the seat.

Grâce à cet agencement, l'inclinaison de l'assise varie proportionnellement à celle du dossier, ce qui permet d'obtenir un excellent confort dans toutes les positions.Thanks to this arrangement, the inclination of the seat varies proportionally to that of the backrest, which provides excellent comfort in all positions.

Divers moyens peuvent être utilisés pour faire varier l'inclinaison du dossier. Dans une forme d'exécution, le système d'encliquetage reliant chaque pied avant à l'accoudoir correspondant est constitué par l'extrémité supérieure du pied avant qui coopère soit avec l'une ou l'autre de plusieurs butées prévues dans un carter allongé aménagé sous l'accoudoir, soit avec l'extrémité avant de ce carter.Various means can be used to vary the inclination of the backrest. In one embodiment, the latching system connecting each front leg to the corresponding armrest consists of the upper end of the front leg which cooperates with either one or more of the stops provided in an elongated casing fitted under the armrest, ie with the front end of this casing.

Pour qu'en période de non utilisation, le siège puisse être stocké à l'état replié sur lui-même, les pieds avant et arrière du piètement sont articulés entre eux, et les deux glissières permettant le passage des deux axes d'articulation du dossier sur les pieds arrière se prolongent vers l'arrière et vers le bas sur une partie de la hauteur des pieds arrière.So that during periods of non-use, the seat can be stored folded back on itself, the front and rear legs of the base are hinged together, and the two slides allowing the two articulation axes to pass through. backrest on the rear legs extend backwards and downwards over part of the height of the rear legs.

Comme cela est connu en soi, ce siège peut, en outre, être équipé d'un repose-pied afin de constituer une véritable chaise longue. Conformément à l'invention, le dossier se prolonge alors vers le bas par deux bras reliés par un axe à deux bielles articuliées au repose-pied qui est lui-même articulé à l'extrémité avant de l'assise; et suivant une autre caractéristique, chacune de ces deux bielles comporte une lumière allongée à l'extrémité avant de laquelle prend appui l'axe d'articulation au bras du dossier lorsque le siège est utilisé, alors que cet axe prend appui à l'extrémité arrière de cette lumière lorsque le siège est replié.As is known per se, this seat can, moreover, be equipped with a footrest in order to constitute a real chaise longue. According to the invention, the backrest then extends downwards by two arms connected by an axis with two connecting rods articulated to the footrest which is itself articulated at the front end of the seat; and according to another characteristic, each of these two connecting rods has an elongated lumen at the front end of which the hinge pin is supported on the arm of the backrest when the seat is used, while this axis is supported at the end back of this light when the seat is folded.

L'invention sera bien comprise, d'ailleurs, et ses avantages ainsi que d'autres caractéristiques ressortiront bien de la description qui suit, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme d'exécution de ce siège.

Dans ce dessin, (1) et (2) désignent respectivement les pieds avant et les pieds arrière constituant le piètement du fauteuil, et (3), (4) et (5) désignent respectivement sa surface d'assise, son dossier et ses accoudoirs.In this drawing, (1) and (2) respectively designate the front legs and the rear legs constituting the base of the chair, and (3), (4) and (5) respectively designate its seating surface, its backrest and its armrests.

Les pieds avant (1) et arrière (2) sont articulés autour d'un axe (6) grâce auquel il est possible de replier le pied arrière (2) sur le pied avant (1) en vue du repliement de l'ensemble du fauteuil; et sur le pied avant (1), l'assise (3) est articulée autour d'un axe transversal (7) situé sensiblement à mi-longueur de l'assise.The front (1) and rear (2) feet are articulated around an axis (6) by means of which it is possible to fold the rear foot (2) on the front foot (1) for the purpose of folding the whole of the armchair; and on the front leg (1), the seat (3) is articulated around a transverse axis (7) located substantially mid-length of the seat.

A son extrémité, arrière, cette assise est articulée par un axe transversal (8) au dossier (4); et sous son extrémité avant, l'assise (3) reçoit un repose-pied (9) qui lui est articulé autour d'un axe transversal (10).At its rear end, this seat is articulated by a transverse axis (8) to the backrest (4); and under its front end, the seat (3) receives a footrest (9) which is articulated to it around a transverse axis (10).

Quant au dossier (4), il est articulé par un axe (12) sur le pied arrière (2); et cette articulation présente l'originalité de se faire par passage de cet axe (12) au travers d'une lumière (13) aménagée dans le pied arrière (2). Cette lumière présente une zone supérieure rectiligne (13a) dans laquelle l'axe (12) se trouve lorsque le siège est en position d'utilisation, ce qui est le cas pour les deux positions représentées respectivement à la figure 1 et à la figure 2. Cette branche (13a) est rectiligne et est légèrement inclinée de haut en bas depuis l'arrière en direction de l'avant du fau- teuiÎ.As for the backrest (4), it is articulated by an axis (12) on the rear leg (2); and this articulation has the originality of being made by passing this axis (12) through a light (13) arranged in the rear leg (2). This light has a rectilinear upper zone (13a) in which the axis (12) is when the seat is in the position of use, which is the case for the two positions shown respectively in FIG. 1 and in FIG. 2 This branch (13a) is straight and is inclined slightly up and down from the rear towards the front of the chair.

La lumière (13) présente une deuxième branche (13b) qui s'étend sur une partie de la hauteur du pied arrière (2) en direction du bas; cette deuxième branche est destinée à servir au coulissement et au logement de l'axe (12) lorsque le siège passe d'une position d'utilisation à la position de repliement complet représentée par la figure 3.The light (13) has a second branch (13b) which extends over part of the height of the rear leg (2) in the direction of the bottom; this two xth branch is intended to be used for sliding and housing the axis (12) when the seat passes from a position of use to the fully folded position shown in FIG. 3.

Chacun des deux accoudoirs (5) est librement articulé sur le dossier (4) autour d'un axe horizontal (14); et sous sa face inférieure, chaque accoudoir est aménagé pour former un petit carter allongé (15) dont la face inférieure est ouverte. Ce petit carter sert au logement, au coulissement et à l'arrêt de l'extrémité supérieure (16) du pied avant correspondant (1).Each of the two armrests (5) is freely articulated on the backrest (4) around a horizontal axis (14); and under its underside, each armrest is arranged to form a small elongated casing (15) whose underside is open. This small housing is used for housing, sliding and stopping the upper end (16) of the corresponding front leg (1).

Quant au repose-pied (9), il est relié par un axe (17) à und bielle (18) située sous l'assise (3). Par un axe (19), cette bielle (18) est articulée à un bras (20) prolongeant le dossier (4) vers le bas. Cet axe (19) traverse non pas un trou circulaire, mais une lumière en arc de cercle (21) aménagée dans la partie arrière de la bielle (18).As for the footrest (9), it is connected by a pin (17) to a connecting rod (18) located under the seat (3). By an axis (19), this connecting rod (18) is articulated to an arm (20) extending the backrest (4) downwards. This axis (19) crosses not a circular hole, but a light in an arc (21) arranged in the rear part of the connecting rod (18).

Lorsque le siège est en position d'utilisation en fauteuil de table, c'est-à-dire occupe la position représentée à la figure 1, le dossier se trouve dans une position rapprochée au maximum de la verticale, l'axe (12) d'articulation de l'ensemble dossier (4) - assise (3) sur les pieds arrière (2) se trouve placé dans la partie arrière de la branche supérieure (13a) de la lumière (13) aménagée dans le pied arrière (2), les accoudoirs (5) occupent une position basse dans laquelle l'extrémité supérieure (16) du pied avant (1) se trouve verrouillée entre la face arrière du petit carter (15) et une butée (22), et le repose-pied (9) est escamoté sous l'assise (3), l'axe (19) d'articulation de chaque bras (20) du dossier se trouvant en appui à l'extrémité avant de la lumière (21) de la bielle (18). Dans cette position de fauteuil de table, l'assise (3) occupe une position très peu inclinée vers le bas depuis l'avant en direction de l'arrière.When the seat is in the table chair use position, that is to say occupies the position shown in FIG. 1, the backrest is in a position as close as possible to the vertical, the axis (12) of articulation of the backrest assembly (4) - seat (3) on the rear legs (2) is placed in the rear part of the upper branch (13a) of the light (13) arranged in the rear leg (2 ), the armrests (5) occupy a low position in which the upper end (16) of the front leg (1) is locked between the rear face of the small casing (15) and a stop (22), and the foot (9) is retracted under the seat (3), the axis (19) of articulation of each arm (20) of the file being in abutment at the front end of the light (21) of the connecting rod ( 18). In this table chair position, the seat (3) occupies a position which is very slightly inclined downwards from the front towards the rear.

Pour passer de cette position de fauteuil de table à cette de fauteuil de relaxation, il suffit de soulever passagèrement les deux accoudoirs (5) et d'exercer une poussée sur le dossier (4) en direction de l'arrière. Lorsque l'extrémité supérieure (16) du pied avant (1) a en effet été degagée de son logement entre la face arrière du carter (15) et la butée (22), le dossier (4) est libre de se déplacer vers l'arrière; et par poussée vers l'arrière, il est possible de l'amener dans la position d'inclinaison recherchée. Si cette poussée est effectuée jusqu'à son maximum, le fauteuil adopte la position de relaxation représentée à la figure 2.To move from this table chair position to that of a relaxation chair, it suffices to temporarily lift the two armrests (5) and exert a push on the backrest (4) towards the rear. When the upper end (16) of the front leg (1) has indeed been released from its housing between the rear face of the casing (15) and the stop (22), the backrest (4) is free to move towards the 'back; and by pushing backwards, it is possible to bring it into the desired tilt position. If this push is carried out to its maximum, the chair adopts the relaxation position shown in Figure 2.

Dans cette position, l'axe (12) d'articulation de l'ensemble dossier (4) - assise (3) sur le pied arrière (2) s'est déplacé en direction de l'avant jusqu'à buter contre l'extrémité avant de la branche (13a) de la lumière (13). Ce déplacement de l'ace (12) conduit, par abaissement de l'ensemble porté par l'axe (12), à un abaissement du dossier (4), de ses bras de prolongement (10) et de son axe (8) d'articulation à l'assise (3). Il en résulte que l'assise pivote autour de son axe (7) d'articulation au pied avant (1), ce qui amène finalement cette assise à occuper une position beaucoup plus inclinée que sa position primitive représentée à la figure 1. Il ressort bien de la figure 2 que l'augmentation de l'inclinaison du dossier (4) vers le bas s'est accompagnée d'une augmentation de l'inclinaison de l'assise vers le bas depuis l'avant en direction de l'arrière.In this position, the axis (12) of articulation of the backrest (4) - seat (3) assembly on the rear foot (2) has moved in the forward direction until it stops against the front end of the branch (13a) of the light (13). This displacement of the ace (12) leads, by lowering the assembly carried by the axis (12), to a lowering of the backrest (4), of its extension arms (10) and of its axis (8) hinge at the seat (3). It follows that the seat pivots about its axis (7) of articulation at the front foot (1), which ultimately causes this seat to occupy a position much more inclined than its original position shown in Figure 1. It emerges Figure 2 shows that the increase in the inclination of the backrest (4) downwards is accompanied by an increase in the inclination of the seat downwards from the front towards the rear. .

Le mouvement de basculement du dossier (4) vers l'arrière s'est en outre accompagné d'un mouvement de dégagement du repose-pied (9) vers le haut. En se délaçant angulairement en direction de l'avant, les deux bras (20) prolongeant le dossier (4) ont en effet exercé par leurs axes (19) une poussée sur l'extrémité avant des lumières (21) des deux bielles (18), amenant ainsi le développement du repose-pied (9) vers l'avant.The backrest tilting movement (4) backwards was also accompanied by an upward movement of the footrest (9). By angularly moving in the direction of the front, the two arms (20) extending the backrest (4) have in fact exerted by their axes (19) a push on the front end of the lights (21) of the two connecting rods (18 ), thus bringing the development of the footrest (9) forward.

Grâce à son agencement, ce fauteuil présente l'avantage de permettre un excellent confort dans ses diverses positions d'utilisation. Au fur et à mesure qu'augmente l'inclinaison du dossier (4) vers l'arrière, l'inclinaison de l'assise (3) de haut en bas et en direction de l'arrière varie en effet dans les mêmes proportions.Thanks to its layout, this chair has the advantage of allowing excellent comfort in its various positions of use. As the inclination of the backrest (4) increases towards the rear, the inclination of the seat (3) from top to bottom and towards the rear varies in effect in the same proportions.

En raison de son agencement, ce fauteuil présente en outre l'avantage de pouvoir, comme le montre la figure 3, être entièrement replié sous un faible encombrement, notamment une faible épaisseur, lorsqu'il n'est pas utilisé. Ce faible encombrement est dû au fait que les divers éléments du fauteuil s'imbriquent entre eux grâce à:

  • - l'articulation des pieds arrière (2) sur les pieds avant (1) autour d'un axe (6),
  • - l'articulation de l'assise (3) à la fois sur les pieds avant (1) autour de l'axe (7), et sur le dossier (4) autour de l'axe (8),
  • - l'articulation des accoudoirs (5) sur le dossier (4) autour des axes (14), et la possibilité de dégagement de ces accoudoirs hors des extrémités supérieures des pieds avant (1),
  • - l'articulation du repose-pied (9) sous l'assise (3) autour d'un axe (10),
  • - l'articulation de l'ensemble dossier (4) - assise (3) sur chaque pied arrière (2) au moyen d'un axe (12) coopérant avec une lumière (13) dont la branche (13b) s'étend sur une partie de la longueur du pied arrière (2),
  • - et la présence dans la partie arrière de chaque bielle (18) d'une lumière (21) jusqu'à l'extrémité arrière de laquelle coulisse, en position de repliement du siège, l'axe (19) d'articulation de cette bielle au bras correspondant (20) du dossier (4).
Because of its arrangement, this chair also has the advantage of being able, as shown in Figure 3, to be fully folded up in a small footprint, especially a small thickness, when not in use. This small footprint is due to the fact that the various elements of the chair interlock with each other thanks to:
  • - the articulation of the rear feet (2) on the front feet (1) around an axis (6),
  • - the articulation of the seat (3) both on the front legs (1) around the axis (7), and on the backrest (4) around the axis (8),
  • - the articulation of the armrests (5) on the backrest (4) around the axes (14), and the possibility of disengaging these armrests from the upper ends of the front legs (1),
  • - the articulation of the footrest (9) under the seat (3) about an axis (10),
  • - the articulation of the backrest assembly (4) - seat (3) on each rear leg (2) by means of an axis (12) cooperating with a light (13) whose branch (13b) extends over part of the length of the rear leg (2),
  • - And the presence in the rear part of each connecting rod (18) of a light (21) to the rear end of which slides, in the folded position of the seat, the axis (19) of articulation of this connecting rod to the corresponding arm (20) of the backrest (4).

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce siège multi- positions qui a été ci-dessus indiquée, à titre d'exemple; elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the sole embodiment of this multi-position seat which has been indicated above, by way of example; on the contrary, it embraces all of its variant embodiments.
