Description

L'invention concerne un siège pliable destiné à équiper les salles recevant du public (amphithéâtres, cinémas, salles de spectacle, salles de conférence, théâtres, etc...).The invention relates to a foldable seat intended to equip the rooms receiving the public (amphitheatres, cinemas, theaters, conference rooms, theaters, etc ...).

Dans l'art antérieur, il est connu des sièges dont l'assise est mobile entre une position d'utilisation sensiblement horizontale et une position pliée afin de limiter l'encombrement du siège lorsqu'il n'est pas utilisé. Ainsi, la mobilité de l'assise permet de répondre à des contraintes normatives et/ou dimensionnelles liés aux salles recevant du public.In the prior art, it is known seats whose seat is movable between a substantially horizontal use position and a folded position to limit the size of the seat when not in use. Thus, the mobility of the seat makes it possible to respond to normative and / or dimensional constraints related to the rooms receiving the public.

Il est notamment connu des sièges à assise mobile dont le dossier est fixe et incliné vers l'arrière afin d'augmenter le confort de l'utilisateur. Cependant, l'inclinaison du dossier augmente l'encombrement du siège lorsqu'il est dans sa position pliée.It is particularly known seats movable seat whose backrest is fixed and tilted back to increase the comfort of the user. However, the inclination of the backrest increases the size of the seat when it is in its folded position.

Il existe également des sièges à assise mobile dont le dossier est fixe et perpendiculaire au sol. Cependant, l'encombrement est diminué au détriment du confort de l'utilisateur.There are also seats with mobile seat whose backrest is fixed and perpendicular to the ground. However, the size is reduced to the detriment of the comfort of the user.

Il existe également des sièges à assise et dossier mobiles, tels que décrit dans les documents US 3093414 A et GB 51087 A .There are also moveable seat and back seats as described in the documents US 3093414 A and GB 51087 A .

L'invention vise à remédier à ces problèmes en proposant un siège pliable possédant une assise inclinée vers l'arrière dans sa position d'utilisation afin d'augmenter le confort de l'utilisateur et présentant un encombrement réduit au maximum dans sa position pliée.The invention aims to remedy these problems by providing a foldable seat having a seat inclined backwards in its position of use to increase the comfort of the user and having a reduced space at the maximum in its folded position.

L'invention vise également à proposer un siège dont le déplacement du dossier et de l'assise s'effectue manuellement et simplement.The invention also aims to provide a seat whose movement of the backrest and the seat is done manually and simply.

À cet effet, et selon un premier aspect, l'invention propose un siège pliable selon la revendication 1.For this purpose, and according to a first aspect, the invention provides a foldable seat according to claim 1.

Ainsi, le dossier est incliné dans sa position d'utilisation et le siège présente un encombrement minimal dans sa position pliée. En effet, le dossier et l'assise sont disposés parallèlement l'un contre l'autre dans la position pliée ce qui permet de réduire au maximum l'encombrement du siège.Thus, the backrest is inclined in its position of use and the seat has a minimal bulk in its folded position. Indeed, the backrest and the seat are arranged parallel to each other in the folded position which minimizes the congestion of the seat.

L'invention propose également un siège dont le déplacement du dossier et de l'assise s'effectue manuellement et dont la position d'équilibre est la position pliée.The invention also proposes a seat whose movement of the backrest and the seat is done manually and whose equilibrium position is the folded position.

Le siège pliable 1, représenté sur la figure 1, possède un pied 2, une assise 3 et un dossier 4.The foldable seat 1, shown on the figure 1 , has a foot 2, a seat 3 and a back 4.

Le pied 2 supporte un dispositif d'articulation du siège. Le dispositif d'articulation comprend une première 5 et une seconde plaque 6 rigide permettant de solidariser respectivement l'assise 3 et le dossier 4 au dispositif d'articulation.The foot 2 supports a seat articulation device. The hinge device comprises a first 5 and a second rigid plate 6 for securing respectively the seat 3 and the backrest 4 to the hinge device.

Le dossier 4 et l'assise 3 sont déplaçables manuellement entre une position pliée dans laquelle ils sont disposés parallèlement l'un contre l'autre et une position d'utilisation.The backrest 4 and the seat 3 are manually movable between a folded position in which they are arranged parallel to each other and a position of use.

La position stable du siège 1 est sa position pliée. L'utilisateur, pour effectuer le déplacement manuel entre la position pliée et la position d'utilisation, appuie sur l'assise 3 afin de provoquer sa rotation par rapport au pied 2. Lors de ce mouvement, le dispositif d'articulation provoque également un déplacement du dossier 4.The stable position of the seat 1 is its folded position. The user, to perform the manual movement between the folded position and the position of use, presses the seat 3 to cause its rotation relative to the foot 2. During this movement, the hinge device also causes a moving the file 4.

Le dispositif d'articulation comprend deux bielles 8, 9. Les bielles 8, 9 permettent de monter le dossier 4, l'assise 3 et le dispositif d'articulation sur le pied 2.The hinge device comprises two rods 8, 9. The rods 8, 9 can be used to mount the backrest 4, the seat 3 and the hinge device on the foot 2.

La première bielle 8 est solidaire de l'assise 3 et montée en rotation par rapport au pied 2 et au dossier 4 respectivement selon un premier 10 et deuxième axe de rotation 11 fixe par rapport au dossier. La seconde bielle 9 est montée en rotation par rapport au pied 2 et au dossier 4 respectivement selon un troisième 12 et quatrième axe 13 de rotation fixe par rapport au dossier.The first rod 8 is secured to the seat 3 and rotatably mounted relative to the foot 2 and the backrest 4 respectively according to a first 10 and second axis of rotation 11 fixed relative to the backrest. The second link 9 is rotatably mounted relative to the foot 2 and the backrest 4 respectively according to a third 12 and fourth axis 13 fixed rotation relative to the folder.

A cet effet, la première 8 et la seconde bielle sont montées d'une part en rotation sur le pied 2 et d'autre part sur la seconde plaque rigide 6.For this purpose, the first 8 and the second connecting rod are mounted on the one hand in rotation on the foot 2 and on the other hand on the second rigid plate 6.

Les quatre axes de rotation 10, 11, 12, 13 forment un quadrilatère déformable. Ainsi, le déplacement de l'assise 3 vers sa position d'utilisation provoque le déplacement vers le haut et le déplacement vers l'arrière du dossier 4 de sorte à disposer le siège 1 dans sa position d'utilisation.The four axes of rotation 10, 11, 12, 13 form a deformable quadrilateral. Thus, the displacement of the seat 3 towards its position of use causes the upward movement and the rearward movement of the backrest 4 so as to arrange the seat 1 in its position of use.

Dans un mode de réalisation particulier de l'invention, le quadrilatère déformable est un parallélogramme.In a particular embodiment of the invention, the deformable quadrilateral is a parallelogram.

Selon un premier mode de réalisation représenté sur les figures 1 à 6, le pied 2 possède une embase 7 disposant d'orifices permettant d'introduire un organe de fixation tel qu'une vis afin de fixer le pied 2 au sol.According to a first embodiment shown on the Figures 1 to 6 , the foot 2 has a base 7 having orifices for introducing a fastener such as a screw to secure the foot 2 to the ground.

Selon un mode de réalisation de l'invention, le pied 2 est creux et enferme un vérin à gaz 14 dont une extrémité est montée en rotation sur le pied et l'autre extrémité est montée en rotation sur l'assise 3 ou sur le dispositif d'articulation tel qu'il est décrit dans le brevet FR 2 790 927 . L'utilisation d'un tel vérin 14 permet de ralentir le déplacement de l'assise 3 et du dossier 4 lorsqu'ils se déplacent vers leur position pliée.According to one embodiment of the invention, the foot 2 is hollow and encloses a gas cylinder 14 whose one end is rotatably mounted on the foot and the other end is rotatably mounted on the seat 3 or on the device articulation as described in the patent FR 2,790,927 . The use of such a jack 14 slows the movement of the seat 3 and backrest 4 when moving to their folded position.

En effet, lorsque l'utilisateur n'exerce plus de pression sur l'assise 3, le poids du dossier 4 provoque le retour du dossier et de l'assise vers leur position pliée. La détente du gaz du vérin 14 permet de ralentir le mouvement du dossier et de l'assise vers leur position pliée de façon efficace et silencieuse. Le mouvement de l'assise 3 et du dossier 4 se fait donc à vitesse constante et contrôlée.Indeed, when the user no longer exerts pressure on the seat 3, the weight of the backrest 4 causes the return of the backrest and the seat to their folded position. The expansion of the gas cylinder 14 slows the movement of the backrest and the seat to their folded position effectively and quietly. The movement of the seat 3 and the backrest 4 is therefore at constant and controlled speed.

Dans un mode de réalisation préférentiel, le vérin 14 utilisé est un vérin dynamique permettant de freiner le déplacement du dossier et de l'assise sur toute leur course.In a preferred embodiment, the jack 14 used is a dynamic cylinder for braking the movement of the backrest and the seat over their entire stroke.

Dans le premier mode de réalisation illustre sur les figures 1 à 6, le siège 1 possède deux accoudoirs 15, 16. Les accoudoirs 15, 16 sont montés en rotation par rapport au dossier 4. Les accoudoirs 15, 16 sont mobiles entre une position déployée et une position rabattue.In the first embodiment illustrated on the Figures 1 to 6 , the seat 1 has two armrests 15, 16. The armrests 15, 16 are rotatably mounted relative to the backrest 4. The armrests 15, 16 are movable between an extended position and a folded position.

Selon un mode de réalisation, les accoudoirs 15, 16 sont également solidarisés à l'assise 3. Ainsi, un mouvement de l'assise 3 vers sa position d'utilisation permet le déploiement des accoudoirs 15, 16 et un mouvement de l'assise 5 vers sa position pliée provoque le rabattement des accoudoirs 15, 16.According to one embodiment, the armrests 15, 16 are also secured to the seat 3. Thus, a movement of the seat 3 towards its position of use allows the deployment of the armrests 15, 16 and a movement of the seat 5 towards its folded position causes the folding of the armrests 15, 16.

Selon le mode de réalisation représenté, des glissières courbées 17 sont disposées dans les accoudoirs 15, 16. Des doigts solidaires de l'assise sont mobiles dans lesdites glissières 17.According to the embodiment shown, curved slides 17 are arranged in the armrests 15, 16. Fingers secured to the seat are movable in said rails 17.

Lorsque les accoudoirs 15, 16 sont dans leur position rabattue, les doigts mobiles se situent sur les parties supérieures des glissières 17. Lors du mouvement de l'assise vers sa position d'utilisation, les doigts mobiles coulissent dans les glissières 17 pour venir en butée contre l'extrémité de la partie inférieure des glissières 17.When the armrests 15, 16 are in their folded position, the movable fingers are located on the upper parts of the slideways 17. During the movement of the seat towards its position of use, the movable fingers slide in the slides 17 to abut against the end of the lower part of the slides 17.

Ainsi, les accoudoirs 15, 16 sont solidarisés à l'assise 3 de telle sorte que la distance entre les accoudoirs 15, 16 et l'assise 3 varie au cours de leur mouvement respectif.Thus, the armrests 15, 16 are secured to the seat 3 so that the distance between the armrests 15, 16 and the seat 3 varies during their respective movements.

Par conséquent, tel qu'il est représenté sur les figures 1 et 6, les accoudoirs 15, 16 sont disposés contre la seconde plaque rigide 6, dans leur position rabattue, lorsque le siège est dans sa position pliée, afin de limiter l'encombrement du siège et les accoudoirs 15,16 sont à distance de l'assise 3, dans leur position déployée, lorsque le siège est dans sa position d'utilisation.Therefore, as represented on the figures 1 and 6 , the armrests 15, 16 are arranged against the second rigid plate 6, in their folded position, when the seat is in its folded position, in order to limit the size of the seat and the armrests 15, 16 are at a distance from the seat 3, in their deployed position, when the seat is in its position of use.

Notons que dans le mode de réalisation représenté figures 1 à 6, le dossier 4 et l'assise 3 ne s'étendent pas sur la totalité de la surface des plaques rigides 5, 6 afin de disposer d'un emplacement pour les accoudoirs 15, 16 lorsque le siège est plié.Note that in the embodiment shown Figures 1 to 6 , the backrest 4 and the seat 3 do not extend over the entire surface of the rigid plates 5, 6 to have a location for the armrests 15, 16 when the seat is folded.

Dans un mode de réalisation préférentiel de l'invention, le dossier 4 présente une forme sensiblement complémentaire à l'assise 3 afin de diminuer l'épaisseur du siège 1 lorsque celui-ci est dans sa position pliée.In a preferred embodiment of the invention, the backrest 4 has a shape substantially complementary to the seat 3 to reduce the thickness of the seat 1 when it is in its folded position.

Tel qu'il est connu par l'homme du métier, le pied 2 possède une butée permettant de définir une position extrême de l'assise 3, et par conséquent du dossier 4, lorsque le siège 1 est dans sa position d'utilisation.As known to those skilled in the art, the foot 2 has a stop for defining an extreme position of the seat 3, and therefore of the backrest 4, when the seat 1 is in its position of use.

Dans un second mode de réalisation de l'invention représenté sur les figures 7 à 9, le pied 2 est composé d'un premier 18 et d'un second élément latéral 19 disposés de part et d'autre de l'assise et du dossier. Chaque élément 18, 19 possède des moyens de fixation au sol.In a second embodiment of the invention shown in Figures 7 to 9 , the foot 2 is composed of a first 18 and a second side member 19 disposed on either side of the seat and backrest. Each element 18, 19 has ground fixing means.

Les éléments latéraux 18, 19 sont agencés pour former accoudoir lorsque ledit siège est dans sa position d'utilisation. A cet effet, chaque élément latéral 18, 19 est équipé d'un repose bras 20, 21 disposé sur l'extrémité supérieure dudit élément latéral. Les repose-bras 20, 21 sont de préférence réalisés en mousse. La hauteur des éléments latéraux 20, 21 est ajustée pour fournir un maximum de confort à l'utilisateur.The side members 18, 19 are arranged to form an armrest when said seat is in its position of use. For this purpose, each lateral element 18, 19 is equipped with a support arm 20, 21 disposed on the upper end of said side member. The armrests 20, 21 are preferably made of foam. The height of the side members 20, 21 is adjusted to provide maximum comfort to the user.

Dans le mode de réalisation représenté, les éléments latéraux 19, 20 comprennent des profilés assemblés pour former un bâti. Les bâtis sont ensuite recouverts de tissu et/ou de mousse.In the embodiment shown, the side members 19, 20 comprise sections assembled to form a frame. The frames are then covered with fabric and / or foam.

La première 8 et la seconde bielle 9 sont d'une part montées en rotation sur un premier élément latéral 18 et d'autre part montées en rotation par rapport au dossier 4 par l'intermédiaire de la seconde plaque rigide 6. Comme dans le mode de réalisation précédent, la première bielle 8 est solidaire de la première plaque rigide 5 et par conséquent de l'assise 3.The first 8 and the second connecting rod 9 are mounted on a first lateral element 18 and rotated relative to the backrest 4 via the second rigid plate 6.
