This frame 2 comprises two substantially vertical arms 3, 4 at the end of which the framework 5 of the backrest is mounted in a tilting fashion; adjustable means such as springs 26, 27 acting as a return spring are fixed between the tilting dynamic framework 5 and the horizontal frame 2, so as to enable the backrest 6 to be adjusted in an angular and dynamic manner. The invention applies to seats, particularly of motor vehicles, aircraft, as well as in the furniture industry.

Description

L'invention a pour objet un siège dynamique dont l'inclinaison du dossier et de l'appui-tête indépendant l'un de l'autre varie en fonction des accélérations et des décélérations et selon la volonté de l'utilisateur. L'invention s'applique aux sièges de véhicules automobiles les aeronefs, ainsi que dans l'ameublement. The subject of the invention is a dynamic seat, the inclination of the backrest and of the headrest independent of one another varies according to the accelerations and decelerations and according to the will of the user. The invention applies to the seats of motor vehicles, aircraft, as well as in furniture.

Actuellement, il existe de nombreux sièges dont le dossier ou siège est réglable angulairement par rapport à la base ou au coussin du siège. Currently, there are many seats whose backrest or seat is angularly adjustable relative to the base or the seat cushion.

Ces réglages peuvent se faire manuellement ou à l'aide d'un moteur électrique. Dans tous les cas, une fois que le réglage du siège est choisi il ne peut être modifié que par la volonté de l'utilisateur. Or, bien souvent l'utilisateur choisit un réglage de son siège pour une position donnée, mais, la fatigue se faisant sentir, l'utilisateur change de position sans changer la position angulaire de son siège. De même, la position de l'utilisateur, la place de sa colonne vertébrale contre le dossier, varient en fonction des différentes accélérations et décélérations du véhicule ; or, le siège ne change pas et ne réagit pas à tous ces paramètres. L'utilisateur a mal au dos et se fatigue, il n'y a pas un massage dynamique de la colonne vertébrale.These adjustments can be made manually or using an electric motor. In any case, once the seat setting is chosen it can only be changed by the will of the user. However, very often the user chooses an adjustment of his seat for a given position, but, fatigue being felt, the user changes position without changing the angular position of his seat. Similarly, the position of the user, the place of his spine against the backrest, vary according to the different accelerations and decelerations of the vehicle; however, the seat does not change and does not react to all these parameters. The user has back pain and gets tired, there is no dynamic massage of the spine.

L'inventeur a déja décrit dans une demande de brevet d'invention un siège dynamique NO FR-A-85 17428 déposée le 22 novembre 1985. Dans cette demande de brevet d'invention, la partie principale du dossier se trouvait solidaire et dans le prolongement de l'axe qui maintenait l'appui-tête. The inventor has already described in a patent application for an invention a dynamic seat NO FR-A-85 17428 filed on November 22, 1985. In this patent application, the main part of the file was secured and in the extension of the axis that held the headrest.

Ainsi l'appui-tête et le dossier ne pouvaient se déplacer indépendamment l'un de l'autre. Or la tête réagit plus vite aux accélérations et aux décélérations, il était donc nécessaire que l'appui-tête se situe dans un plan mobile dynamique indépendant de celui du dossier. Cette solution technique permet, notamment, d'éviter le "coup du lapin".Thus the headrest and the backrest could not move independently of each other. However, the head reacts faster to accelerations and decelerations, so it was necessary for the headrest to be in a dynamic mobile plane independent of that of the backrest. This technical solution makes it possible, in particular, to avoid "whiplash".

A cet effet, le siège selon l'invention est composé d'un châssis horizontal qui reçoit la partie horizontale non mobile du siège, ce châssis comporte deux bras sensiblement verticaux à l'extrémité desquels est monté un axe horizontal sur lequel est monté oscillant le cadre du dossier
Des moyens réglables tels que des ressorts faisant office de ressort de rappel sont fixés entre le cadre dynamique oscillant et le châssis horizontal, de manière à permettre le réglage angulaire dynamique du dossier.To this end, the seat according to the invention is composed of a horizontal frame which receives the non-movable horizontal part of the seat, this frame comprises two substantially vertical arms at the end of which is mounted a horizontal axis on which is mounted oscillating the file frame
Adjustable means such as springs acting as return spring are fixed between the oscillating dynamic frame and the horizontal frame, so as to allow dynamic angular adjustment of the backrest.

La partie supérieure du cadre comporte un cylindre monté rotatif autour de la traverse dudit cadre, sur ce cylindre est fixé l'armature qui reçoit 1 'appui-tête, des moyens réglables faisant office de ressort de rappel sont fixés entre le cadre et le châssis, des moyens de commande permettent de faire varier l'angle de l'armature de l'appui-tête par rapport au cadre. The upper part of the frame comprises a cylinder rotatably mounted around the crosspiece of said frame, on this cylinder is fixed the frame which receives one headrest, adjustable means acting as return spring are fixed between the frame and the chassis , control means make it possible to vary the angle of the frame of the headrest relative to the frame.

Ledit moyen de commande peut être un câble. Said control means can be a cable.

Les moyens faisant office de ressort de rappel peuvent être des ressorts qui sont disposés entre la traverse inférieure du cadre rotatif du dossier et l'une des traverses horizontales du châssis horizontal. The means acting as return spring can be springs which are arranged between the lower cross member of the rotary frame of the backrest and one of the horizontal cross members of the horizontal frame.

L'armature mobile de l'appui-tête et le cadre dudit dossier sont reliés de manière dynamique par des moyens d'asservissement. L'axe cylindrique sur lequel est fixée l'armature comporte une poulie fixe et une poulie rotative est montée sur la traverse inférieure du cadre du dossier , un câble est fixé à une traverse horizontale du châssis, puis ledit câble vient sur la poulie rotative de la traverse inférieure du cadre et passe par les autres traverses dudit cadre, puis est frappé après les quelques tours nécessaires sur la poulie fixe, de manière à ce que le déplacement du dossier en inclinaison vers l'arrière de sa partie supérieure entraine la rotation du sommet de l'armature de l'appui-tête vers l'avant. The movable frame of the headrest and the frame of said backrest are dynamically connected by servo means. The cylindrical axis on which the frame is fixed comprises a fixed pulley and a rotary pulley is mounted on the lower cross member of the backrest frame, a cable is fixed to a horizontal cross member of the frame, then said cable comes on the rotary pulley of the lower cross member of the frame and passes through the other cross members of said frame, then is struck after the necessary few turns on the fixed pulley, so that the displacement of the backrest in inclination towards the rear of its upper part causes the rotation of the top of the headrest frame forward.

Un moyen de commande permet de manoeuvrer à volonté 1 'appui-tête indépendamment du dossier. L'axe cylindrique sur lequel est montée l'armature de l'appui-tête comporte un moyen faisant office de bras de levier et auquel est fixé l'extrémité d'un câble. L'autre extrémité du câble est munie d'une poignée de manoeuvre et est disposée au niveau d'un des bras verticaux dans un support dans lequel il coulisse, ledit support étant lui fixé au bras vertical. A control means makes it possible to maneuver the headrest independently of the backrest. The cylindrical axis on which the armature of the headrest is mounted comprises means acting as a lever arm and to which the end of a cable is fixed. The other end of the cable is provided with an operating handle and is arranged at one of the vertical arms in a support in which it slides, said support being fixed to the vertical arm.

Des moyens de blocage permettent à volonté à l'utilisateur de bloquer le balancement du cadre du dossier . Le cadre comporte, dans sa partie inférieure, une glissière en arc de cercle dans laquelle viennent un boulon et un écrou qui peuvent être serrés par une molette empêchant ainsi tout balancement du cadre
Les dessins ci-joints sont donnés à titre d'exemple indicatif et non limitatif. Ils représentent un mode de réalisation préféré selon l'invention. Ils permettront de comprendre aisément l'invention.Blocking means allow the user to block the swinging of the backrest frame at will. The frame has, in its lower part, a slide in an arc of circle in which come a bolt and a nut which can be tightened by a knob thus preventing any swinging of the frame
The attached drawings are given by way of non-limiting example. They represent a preferred embodiment according to the invention. They will allow the invention to be easily understood.

Le siège 1 est composé d'un châssis 2 horizontal qui reçoit la partie horizontale non mobile du siège et qui n'est pas représenté à la figure 1. The seat 1 is composed of a horizontal frame 2 which receives the non-movable horizontal part of the seat and which is not shown in FIG. 1.

Ce châssis 2 comporte deux bras 3, 4 sensiblement verticaux à l'extrémité desquels est monté oscillant le cadre 5 du dossier.This chassis 2 comprises two substantially vertical arms 3, 4 at the end of which the frame 5 of the backrest is mounted to oscillate.

Des moyens réglables tels que des ressorts 26, 27 faisant office de ressort de rappel sont fixés entre le cadre dynamique oscillant 5 et le châssis horizontal 2, de manière à permettre le réglage angulaire dynamique du dossier 6. Adjustable means such as springs 26, 27 acting as return spring are fixed between the oscillating dynamic frame 5 and the horizontal frame 2, so as to allow dynamic angular adjustment of the backrest 6.

La partie supérieure 7 du cadre 5 comporte un cylindre 8 monté rotatif autour de la traverse 9 dudit cadre 5, sur ce cylindre 8 est fixé l'armature 10 qui reçoit l'appui-tête, des moyens réglables faisant office de resort de rappel sont fixés entre le cadre et le châssis, des moyens de commande 12 permettent de faire varier l'angle de 1' armature 10 de l'appui-tête par rapport au cadre 5. The upper part 7 of the frame 5 comprises a cylinder 8 rotatably mounted around the cross member 9 of the said frame 5, on this cylinder 8 is fixed the frame 10 which receives the headrest, adjustable means acting as a return resort are fixed between the frame and the chassis, control means 12 make it possible to vary the angle of the frame 10 of the headrest relative to the frame 5.

Ledit moyen de commande peut être un câble 12. Said control means can be a cable 12.

Les moyens faisant office de ressort de rappel peuvent être des ressorts 6, 7 qui sont disposés entre la traverse inférieure 16 du cadre rotatif 5 du dossier 6 et l'une des traverses horizontales 13 du châssis 2 horizontal. The means acting as a return spring can be springs 6, 7 which are arranged between the lower cross member 16 of the rotary frame 5 of the backrest 6 and one of the horizontal cross members 13 of the horizontal frame 2.

L'armature mobile 10 de l'appui-tête et le cadre 5 dudit dossier 6 sont reliés de manière dynamique par des moyens d'asservissement. L'axe cylindrique 8 sur lequel est fixée l'armature 10 comporte une poulie fixe 14 et une poulie rotative 15 est montée sur la traverse inférieure 16 du cadre 5 du dossier 6, un câble 12 est fixé à une traverse horizontale 17 du châssis 2, puis ledit câble 11 vient sur la poulie rotative 15 de la traverse inférieure 16 du cadre 5 et passe par les autres traverses dudit cadre 5 puis est frappé après les quelques tours nécessaires sur la poulie fixe 14, de manière à ce que le déplacement du dossier 6 en inclinaison vers l'arrière de sa partie supérieure 7 entraine la rotation du sommet de l'armature 10 de l'appui-tête vers l'avant. The movable frame 10 of the headrest and the frame 5 of said backrest 6 are dynamically connected by servo means. The cylindrical axis 8 on which the frame 10 is fixed comprises a fixed pulley 14 and a rotary pulley 15 is mounted on the lower cross member 16 of the frame 5 of the backrest 6, a cable 12 is fixed to a horizontal cross member 17 of the chassis 2 , then said cable 11 comes on the rotary pulley 15 of the lower cross member 16 of the frame 5 and passes through the other cross members of said frame 5 then is struck after the few necessary turns on the fixed pulley 14, so that the displacement of the backrest 6 inclined towards the rear of its upper part 7 causes the top of the frame 10 of the headrest to rotate forward.

Un moyen de commande 12 permet de manoeuvrer à volonté l'appui-tête indépendamment du dossier 6. L'axe cylindrique 8 sur lequel est montée l'armature de l'appui-tête comporte un moyen faisant office de bras de levier 18 et auquel est fixé l'extrémité 19 d'un câble 12. L'autre extrémité 20 du câble 12 est munie d'une poignée de manoeuvre 21 et est disposée au niveau d'un des bras verticaux 3 dans un support 22 dans lequel il coulisse, ledit support 22 étant lui fixé au bras vertical 3. A control means 12 allows the headrest to be maneuvered independently of the backrest 6. The cylindrical axis 8 on which the frame of the headrest is mounted comprises means acting as a lever arm 18 and to which the end 19 of a cable 12 is fixed. The other end 20 of the cable 12 is provided with an operating handle 21 and is disposed at one of the vertical arms 3 in a support 22 in which it slides, said support 22 being fixed to the vertical arm 3.

Des moyens de blocage 23 permettent à volonté à l'utilisateur de bloquer le balancement du cadre 5 du dossier 6. Le cadre 5 comporte dans sa partie inférieure une glissière 24 en arc de cercle dans laquelle viennent un boulon et un écrou qui peuvent être serrés par une molette 23 empêchant ainsi tout balancement du cadre 5. Locking means 23 allow the user at will to block the swinging of the frame 5 of the backrest 6. The frame 5 has in its lower part a slide 24 in an arc of a circle in which come a bolt and a nut which can be tightened by a wheel 23 thus preventing any swinging of the frame 5.

Dans la figure 6 le siège est représenté schématiquement avec un dossier 25 et son appui-tête 26. C'est le mouvement du dossier 25 sur son axe qui empêche l'engourdissement et le tassement de la colonne vertébrale 27 et permet ainsi un échange constant entre la tête, le tronc et les jambes evitant ainsi la fatigue, les douleurs, le sommeil et tous les autres inconvénients. La tête se trouve en contact permanent avec l'appui-tête 26.  In Figure 6 the seat is shown schematically with a backrest 25 and its headrest 26. It is the movement of the backrest 25 on its axis which prevents numbness and compaction of the spine 27 and thus allows a constant exchange between the head, trunk and legs thus avoiding fatigue, pain, sleep and all other inconveniences. The head is in permanent contact with the headrest 26.
