Abstract

Device intended for articulated chairs comprising a tiltable backrest 2 and a tiltable seat 1. According to the invention the tilting of the backrest causes the automatic tilting of the seat or, conversely, the tilting of the seat causes the tilting of the backrest. For this purpose, the length 10 between the point 7 of the lever 6 and the point 8 of the seat 1 is given material form. The same applies to the length 11 between the point 8 and a point 9 on the base 3. The sum 10 + 11 of these lengths is not extensible and optionally not reducible.

Description

la présente invention concerne un systenie permettant d'incliner, en fonction l'un de l'autre, le dossier et l'assise d'un fauteuil, grace a une seule commande. en général pour incliner le dossier et l'assise, il faut deux commandes. le dispositif selon l'invention permet de moduler la variation de chacune des deux inclinaisons respectives, dossier et assise, selon le meilleur critère. le système est simple, s'integre au fauteuil et n'est pas apparent.the present invention relates to a system making it possible to tilt, as a function of one another, the backrest and the seat of an armchair, by means of a single command. in general to tilt the backrest and the seat, two commands are required. the device according to the invention makes it possible to modulate the variation of each of the two respective inclinations, backrest and seat, according to the best criterion. the system is simple, fits into the chair and is not visible.

selon l'invention, le fauteuil est constitué de l'assise (1), du dossier (2), d'un montant ou piètement (3) relié au sol.according to the invention, the armchair consists of the seat (1), the backrest (2), an upright or base (3) connected to the ground.

l'assise s'articule autour d'un point (4); le dossier s'articule autour d'un point (5). (4) et (5) pouvant être confondus.the seat is articulated around a point (4); the file revolves around a point (5). (4) and (5) can be confused.

le dossier comporte un levier (6) pouvant etre conçu comme un arbre à came.the backrest includes a lever (6) which can be designed as a camshaft.

selon l'invention, la longueur (10), comprise entre le point (7) extrémité du levier (6) du dossier et le point (8) solidaire de l'assise, varie, lorsque le dossier s'incline.according to the invention, the length (10), between the point (7) end of the lever (6) of the backrest and the point (8) secured to the seat, varies when the backrest tilts.

de même la longueur (11), comprise entre le point (8) et le point (9) solidaire du piètement, varie lorsque l'assise s'incline. similarly the length (11), between the point (8) and the point (9) integral with the base, varies when the seat reclines.

selon l'invention , des moyens sont prévus, pour que la longueur (10+11) somme des longueurs (10)et (11) soit pour le moins non extensible , et facultativement,non réductible.seront utilisés., par exemple, cable, sangle,flexible, jeux de biellettes, renvois articulés, ou tout autre moyen sans limitation.according to the invention, means are provided, so that the length (10 + 11) sum of the lengths (10) and (11) is at least non-extendable, and optionally, not reducible. will be used., for example, cable , strap, flexible, sets of links, articulated references, or any other means without limitation.

ainsi, lorsque la longueur (10) diminue, sous l'action du dossier s'inclinant en arrière, la longueur (11) augmente et l'assise se relève.lorsque la longueur (10) augmente, le dossier se relevant, la longueur (11) diminue, contraignant l'assise à s'abaisser.thus, when the length (10) decreases, under the action of the backrest tilting back, the length (11) increases and the seat rises. When the length (10) increases, the backrest rises, the length (11) decreases, forcing the seat to lower.

selon une variante l'inverse est possible: les variations de la longueur (11) commandant la longueur (10).according to a variant the reverse is possible: variations in the length (11) controlling the length (10).

le dispositif selon l'invention permet dtincliner très faiblement l'assise pendant que le dossier sera incliné, de la verticale jusqu'a l'horizontale. en équilibrant judicieusement les proportions entre le levier du dossier (6) et les positionnements des points (4), (9), (8), le dossier s'incline de 90 degrés, pendant que l'assise s'incline d'un angle beaucoup plus réduit, par exemple 20 ou 30 degrés.la variation de la longueur (10) correspondant à un angle de 90 degrés du dossier, pendant que la même variation de la longueur (11) correspond à un angle de 20 degrés de l'assise. the device according to the invention makes it possible to tilt the seat very slightly while the backrest is tilted, from the vertical to the horizontal. by judiciously balancing the proportions between the backrest lever (6) and the positions of points (4), (9), (8), the backrest reclines by 90 degrees, while the seat reclines by a much smaller angle, for example 20 or 30 degrees, the variation in length (10) corresponding to a 90-degree angle of the backrest, while the same variation in length (11) corresponds to an angle of 20 degrees in l 'seated.

selon une variante, l'invention permet de limiter la course de l'un des deux éléments,par exemple l'assise, pendant que l'autre élément, par exemple le dossier, continue sa course. en limitant la variation de la longueur (11), le dossier continuera de s'incliner, pendant que l'assise sera bloquée en une position prédéterminée. dans ce cas, la longueur (10+11) sera prévue simplement non extensible, mais reductible, par exemple avec un cable.according to a variant, the invention makes it possible to limit the stroke of one of the two elements, for example the seat, while the other element, for example the backrest, continues its stroke. by limiting the variation in length (11), the backrest will continue to tilt, while the seat will be locked in a predetermined position. in this case, the length (10 + 11) will be provided simply not extensible, but reducible, for example with a cable.

selon une variante, l'invention permet de soumettre l'assise (1) à l'action d'un ressort qui la maintient inclinée vers le haut dans la limite de la longueur (11). l'utilisateur par une pression, de son propre poids par exemple, pourra si il le désire, ramener l'assise à la position horizontale, par la compression du ressort, indépendament de l'action induite par toute modification de la longueur (I0) donc de la position du dossier (2). dans ce cas la longueur (10+11) sera prévue simplement non extensible mais réductible, par exemple avec un cable. according to a variant, the invention makes it possible to subject the seat (1) to the action of a spring which keeps it inclined upwards within the limit of the length (11). the user by a pressure, of his own weight for example, can if he wishes, bring the seat to the horizontal position, by the compression of the spring, independently of the action induced by any modification of the length (I0) therefore the position of the backrest (2). in this case the length (10 + 11) will be provided simply not extensible but reducible, for example with a cable.
