2871348 ASSISE DE SIEGE A FLANCS ANTERIEURS VARIABLES2871348 SEAT SEAT WITH VARIABLE ANTERIOR FLANKS
La présente invention concerne une conception d'assise de siège qui de part des mécanismes réglables peut modifier la surface d'appuis de celui ci et de part la même, modifier l'inclinaison du bassin et donc la position avant arrière de l'utilisateur. The present invention relates to a seat-seat design which, on the basis of the adjustable mechanisms, can modify the support surface of the latter and, by the same, modify the inclination of the pelvis and therefore the front-back position of the user.
Ce système avec une assistance motorisée est particulièrement adapté pour les métiers d'ophtalmologie mais peut être utile pour l'ensemble des personnes positionné sur une assise face à un poste de travail ou en position repos arrière (autocar). This system with motorized assistance is particularly suitable for the ophthalmic trades but can be useful for all people positioned on a seat in front of a workstation or in a rest position (bus).
Les dessins annexés permettront de mieux comprendre les descriptifs et les différentes variantes en construction de cette application: Assise à flancs inclinables - Assise à flancs déformables, avec un schéma permettant de voir l'influence de la forme de l'assise. The attached drawings will help to better understand the descriptions and the different variants of this application: Reclining side seat - Seating with deformable sidewalls, with a diagram to see the influence of the shape of the seat.
Descriptif Le principe de fonctionnement consiste donc à modifier la surface de l'assise de chaque coté, au niveau des muscles inférieurs des cuisses pour ne garder que la partie fessier en appuis en position travail. Pour mieux comprendre, il faut savoir que dans une assise normale complète, le buste d'une personne sans contrainte, prend une position angulaire de quatre vingt dix degrés par rapport à l'assise qui est horizontale. Description The operating principle therefore consists of modifying the surface of the seat on each side, at the level of the lower muscles of the thighs to keep only the gluteal portion in support in the working position. To better understand, you should know that in a full normal seat, the bust of a person without constraint, takes an angular position of ninety degrees relative to the seat which is horizontal.
Hors pour une position de travail, vingt à trente degrés d'inclinaison en avant pour le buste sont nécessaires. Ceci entraîne une compression des muscles inférieurs des cuisses et provoque des tensions dans le dos avec une courbure de celui ci néfaste pour la colonne vertébrale. Out for a working position, twenty to thirty degrees of forward tilt for the bust are needed. This causes compression of the lower muscles of the thighs and causes tension in the back with a curvature of the latter harmful for the spine.
En dégagent l'assise au niveau des cuisses on va sans contrainte, faire basculer le bassin en avant et de part ce fait incliner naturellement le buste en maintenant droite la colonne vertébrale, sans contraintes musculaires. In clearing the seat at the thighs we go without constraint, tilt the pelvis forward and therefore naturally incline the bust while keeping the spine straight, without muscle stresses.
Cas inverse, si l'on veut avoir une position repos arrière on va remonter les flancs d'assise afin de basculer le bassin en position arrière. Conversely, if one wants to have a rest position back we will go up the sidewalls to tilt the pelvis back position.
La conception de l'assise est donc réalisée en trois éléments différents dans le cas d'une conception d'assise rigide: la partie centrale référencée 1, le flanc gauche 2 et le flanc droit 3. La ligne de découpe des flancs doit se situer au niveau du passage des muscles inférieurs des cuisses, afin de garder en appuis que les muscles des fesses. The design of the seat is therefore made of three different elements in the case of a rigid seat design: the central part referenced 1, the left flank 2 and the right flank 3. The cutting line of the flanks must be located at the level of the passage of the lower muscles of the thighs, to keep in support that the muscles of the buttocks.
Il est possible que l'assise soit réalisée en une seule pièce, mais avec une matière souple au 30 niveau des lignes de passage des parties mobiles afin qu'elle soit déformable par une action mécanique extérieure ou par sa propre charge. It is possible that the seat is made in one piece, but with a flexible material at the level of the passage lines of the moving parts so that it is deformable by an external mechanical action or by its own load.
Le principe de déplacement des pièces de flancs peut être réalisé par déplacement de ceux ci d'une manière parallèle par déplacement de l'assise centrale ou bien par rotation des flancs par rapport à l'assise centrale. The principle of displacement of the side pieces can be achieved by moving them in a parallel manner by moving the central seat or by rotation of the sidewalls relative to the central seat.
Z 2871348 Trois positions d'assise caractérisent l'invention. Z 2871348 Three seating positions characterize the invention.
Le système en position que l'on va appeler bassin relevé forme une assise complète avec un angulaire des assises latérales qui prennent un angle relevé , afin d'incliner le dos en arrière en accentuant l'appui sur les muscles des cuisses. The system in the position that is going to be called the raised pelvis forms a complete seat with an angular side seating that takes a raised angle, to tilt the back back by accentuating the support on the muscles of the thighs.
Le système en position que l'on va appeler bassin normal forme une assise complète avec les assises latérales alignées avec celle du centre. The system in position that we will call normal basin forms a complete seat with the side seats aligned with that of the center.
Le système en position que l'on va appeler bassin incliné possède les assises latérales positionnées angulaires négativement par rapport à l'horizontale afin de garder uniquement les muscles fessier en appuis. The system in the position that is going to be called inclined pelvis has the lateral seats positioned angularly negatively relative to the horizontal in order to keep only the gluteal muscles in support.
La mise en oeuvre de ce système consiste par une articulation des flancs 2 et 3 par rapport à un point fixe situé sur la pièce centrale 1.Les mécanismes de déplacement des flancs 2 et 3 sont réalisés avec une architecture classique type moteur / vis / came ou levier mais ont la particularité de se déplacer ensemble d'une façon identique de chaque coté de l'assise centrale. The implementation of this system consists of an articulation of the sidewalls 2 and 3 with respect to a fixed point located on the central part 1.The mechanisms of displacement of the sidewalls 2 and 3 are made with a conventional architecture type motor / screw / cam or lever but have the distinction of moving together in an identical way on each side of the central seat.
Il est évident que cette manipulation du bassin par modification de l'assise peut être utilisé pour incliner le buste dans une bonne position de travail, mais dans le cas d'un montage motorisé, une gestion des mouvements d'une façon cyclique, peut avoir comme action un travail bénéfique sur la colonne vertébrale. It is obvious that this manipulation of the basin by changing the seat can be used to incline the bust in a good working position, but in the case of a motorized mounting, a movement management in a cyclical manner, may have as action a beneficial work on the spine.
