Abstract

Round articulation without a satellite characterised in that the fixed ring 3 is rendered integral with the fixed armature 1 of the seat cushion of a seat by a shim 6 interacting with nuts and bolts 4, this fixed ring 3 having external teeth 8 intended to interact with the internal teeth 21 of a movable ring 20 fixed to the movable armature 24 of the backrest of the seat in question, the rotational driving of the movable ring 20 relative to the fixed ring 3 being provided by the rotation of a double cam 12-18 whose eccentricity brings about the angular displacement of the movable ring 20 whose internal teeth 21 rotate on the fixed teeth 8 of the fixed ring 3, these two fixed and movable rings 3, 20 being held on one another by a fixed circular cage 27.

Description

Les sièges d'automobile sont maintenant systématiquement munis d'articulations permettant le réglage du dossier d'un siège par rapport à l'assise afin de donner au passager un confort maximum rédui sane la fatigue, ceci étant très important pour le conducteur puisque l'on augmente ainsi la sécurité sur route. Automobile seats are now systematically provided with articulations allowing the adjustment of the back of a seat relative to the seat in order to give the passenger maximum comfort reduced without fatigue, this being very important for the driver since the road safety is thus increased.

Ces articulations, qui doivent être montées sur plusieurs types de sièges, doivent donc être très facilement adaptables tout en ayant, d'une part, un volume le plus réduis possible et, d'autre part, une résistance la plus grande possible. Toutefois, ces articulations sont onéreuses et, c ' est pourquoi, il est nécessaire de créer des mécanismes d'articulation très simples afin de pouvoir équiper les véhicules de bas de gamme. These joints, which must be mounted on several types of seats, must therefore be very easily adaptable while having, on the one hand, the smallest possible volume and, on the other hand, the greatest possible resistance. However, these joints are expensive and, therefore, it is necessary to create very simple joint mechanisms in order to be able to equip low-end vehicles.

C'est le but de la présense invention. This is the aim of the present invention.

Conformément à l'invention, l'articulation ronde sans satellite comporte une couronne fixe qui est rendue solidaire, de l'armature fixe de l'assise d'un siège, par une cale d'épaisseur en coopération avec des boulons et écrous, cette couronne fixe présentant une denture extérieure destinée à coopérer avec la denture intérieure d'une couronne mobile fixée sur l'armature mobile du dossier du siège considéré, l'entralnemeni en rotation de la couronne mobile par rapport à la couronne fixe étant produit par la rot a ilion d'une came double dont l'excentration provoque le déplacement angulaire de la couronne mobile dont la denture intérieure roule sur la denture fixe de la couronne fixe, ces deux couronnes fixe et mobile étant maintenues l'une sur l'autre par une cage circulaire fixe. In accordance with the invention, the round joint without satellite comprises a fixed crown which is made integral with the fixed frame of the seat of a seat, by a thickness block in cooperation with bolts and nuts, this fixed crown having an external toothing intended to cooperate with the internal toothing of a movable crown fixed on the movable frame of the seat back considered, the rotationally centralization of the movable crown relative to the fixed crown being produced by the rot a ilion of a double cam whose eccentricity causes the angular displacement of the mobile crown whose internal toothing rolls on the fixed toothing of the fixed crown, these two fixed and mobile crowns being held one on the other by a fixed circular cage.

Suivant une autre caractéristique de l'invention, sur la partie de la came double est monté un roulement à aiguilles ou à rouleaux interposé entre la périphérie de la came et le trou circulaire central prévu dans la couronne fixe. According to another characteristic of the invention, on the part of the double cam is mounted a needle or roller bearing interposed between the periphery of the cam and the central circular hole provided in the fixed crown.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé. An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.

La fig. 1 est une élévation de face partiellement en coupe du dispositif d'articulasion du dossier du siège par rapport à l'assise, étant entendu que l'articulation de gauche est vue en coupe diamétrale. Fig. 1 is a front elevation partially in section of the articulation device of the seat back relative to the seat, it being understood that the articulation on the left is seen in diametrical section.

La fig. 2 est une coupe prise suivant la ligne Il-Il de la fig. 1.  Fig. 2 is a section taken along the line Il-Il of FIG. 1.

La fig. 3 est une coupe, à grande échelle, de la partie inférieure de l'articulation de la fig. 1.  Fig. 3 is a section, on a large scale, of the lower part of the joint of FIG. 1.

A la fig. 1, on a représenté les parties terminales de l'armature 1 de l'assise qui affectent la forme de flasques plats percés de six trous ronds 2 disposés à 60 les uns par rapport aux autres. In fig. 1, there is shown the end parts of the frame 1 of the seat which affect the shape of flat flanges drilled with six round holes 2 arranged at 60 relative to each other.

Une couronne circulaire fixe 3 est maintenue sur l'armature fixe 1 par l'intermédiaire de boulons et écrous 4 qui serrent la couronne fixe 3 sur l'armature fixe 1 par l'intermédiaire d'une cale d'épaisseur 5 de forme circulaire, cette cale d'épaisseur présentant sur son pourtour gauche des surépaisseurs 6 pénétrant dans les trous 2 précités tandis que la partie droite de la cale d'épaisseur comporte des évidements 7 dans lesquels pénètrent des surépaisseurs 3a disposées à 60 les unes des autres de la couronne fixe 3. Ceste dernière présente intérieurement une denture 8 circulaire qui est donc fixe et dont le roule sera expliqué plus loin. A fixed circular ring 3 is held on the fixed frame 1 by means of bolts and nuts 4 which tighten the fixed ring 3 on the fixed frame 1 by means of a wedge of thickness 5 of circular shape, this thickness shim having on its left periphery extra thicknesses 6 penetrating the aforementioned holes 2 while the right part of the thickness shim has recesses 7 into which penetrate extra thicknesses 3a arranged at 60 from each other of the crown fixed 3. Ceste last internally has a circular toothing 8 which is therefore fixed and the roll of which will be explained later.

La couronne fixe 3 est percée, en son centre, d'un trou circulaire 9 contenant une bague 10 formant cage pour des rouleaux ou aiguilles 11 qui reposent égalemeni sur la périphérie d'une came 12 solidaire d'un arbre 13 présentant extérieurement un bout d'arbre de grand diamètre 13a traversant des trous 14-15 percés, le premier dans la zone centrale de la cale d'épaisseur 6 et le second dans l'armature fixe 1 de l'assise. The fixed crown 3 is pierced, in its center, with a circular hole 9 containing a ring 10 forming a cage for rollers or needles 11 which also rest on the periphery of a cam 12 secured to a shaft 13 having an outer end of large diameter shaft 13a passing through holes 14-15 drilled, the first in the central zone of the shim of thickness 6 and the second in the fixed frame 1 of the seat.

La came 12 est prolongée par une deuxième came 18 plus petite mais de forme semblable à celle de la came 12. The cam 12 is extended by a second smaller cam 18 but of a shape similar to that of the cam 12.

Comme on peut le voir à la fig. 1, des rivets 19 maintiennent également la couronne fixe 3 sur la cale d'épaisseur 6 dans les trous ne comportant pas les boulons et écrous 4,en général, les trois boulons et écrous 8 et les trois rivets 19 sont disposés à 120 les uns par rapport aux autres. As can be seen in fig. 1, rivets 19 also hold the fixed crown 3 on the shim 6 in the holes not comprising the bolts and nuts 4, in general, the three bolts and nuts 8 and the three rivets 19 are arranged at 120 each compared to others.

La came 18 porte une couronne mobile 20 présentant une denture intérieure 21 destinée à coopérer avec la denture fixe 8 de la couronne fixe 3. La den ture mobile 21, du fait du montage de la couronne mobile 20 sur la came 18, engrène ,à la partie supérieure de l'articulation, avec la denture fixe 8 tandis qu'elle est totalement désengagée de la denture fixe à la partie inférieure. The cam 18 carries a movable crown 20 having an internal toothing 21 intended to cooperate with the fixed toothing 8 of the fixed crown 3. The movable den ture 21, due to the mounting of the movable crown 20 on the cam 18, meshes with the upper part of the joint, with the fixed toothing 8 while it is completely disengaged from the fixed toothing at the lower part.

Ainsi, comme le montre la fig. 2, la denture mobile 21 ne coopère avec la denture fixe que dans la zone A-A1 supérieure. Thus, as shown in fig. 2, the mobile toothing 21 only cooperates with the fixed toothing in the upper zone A-A1.

La couronne mobile, qui présente un découpage 20a vers la droise, est liée par des boulons et écrous 22 à l'armature du dossier 24 de la même manière que la couronne à l'armature fixe 3 de l'assise. Les découpages 20a successifs forment ainsi chacun une protubérance qui pénètre dans les trous 26 percés à 60 dans l'armature mobile 24 du dossier. The movable crown, which has a cutout 20a to the right, is linked by bolts and nuts 22 to the frame of the backrest 24 in the same way as the crown to the fixed frame 3 of the seat. The successive cutouts 20a thus each form a protuberance which penetrates into the holes 26 drilled at 60 in the movable frame 24 of the backrest.

On obtiens ainsi un centrage parfait de la couronne mobile 20 sur l'armature du dossier 24.  This gives perfect centering of the movable crown 20 on the frame of the backrest 24.

Finalement, le maintien de la couronne mobile 20 par rapport à la couronne fixe 3 est assuré par une cage 27 entourant la périphérie extérieure de la couronne fixe 3 et la couronne mobile 20 mais, il est prévu un chemin de billes 28 à la périphérie exsé- rieure de la couronne mobile 20 dans une gorge circulaire 20b de cette dernière pour faciliter la rotation de la couronne mobile 20 dans la cage 27 qui est fixe. Finally, the maintenance of the movable crown 20 relative to the fixed crown 3 is ensured by a cage 27 surrounding the outer periphery of the fixed crown 3 and the movable crown 20 but, a path of balls 28 is provided at the periphery exsé - The lower part of the mobile crown 20 in a circular groove 20b of the latter to facilitate the rotation of the mobile crown 20 in the cage 27 which is fixed.

L'arbre 13 relie normalement deux articulations identiques de façon à assurer la mobilité du dossier du siège par rapport à Irassise bien que, dans certains cas, il ne soit pas possible de n'avoir qu'une seule articulation sur un seul côté du siège, l'autre côté comportant simplement sur l'armature du siège 24 un axe autour duquel tourne l'armature du dossier. The shaft 13 normally connects two identical joints so as to ensure the mobility of the seat back relative to Irassise although, in some cases, it is not possible to have only one joint on one side of the seat , the other side simply comprising on the frame of the seat 24 an axis around which the frame of the backrest rotates.

Comme cela est représenté schématiquement à la fig. 1, l'entraînement en rotation des cames 12 et 18 se fait par le bout de l'arbre 13a au moyen d'un bouton de commande 30. As shown schematically in FIG. 1, the cams 12 and 18 are driven in rotation by the end of the shaft 13a by means of a control button 30.

Lorsque l'on veut actionner le dispositif autrement qu'à la main, on peut également remplacer
cette commande manuelle, placée tantôt à droite, tan- tat à gauche du siège, suivant ltespace libre prévu pour cette commande dans le véhicule considéré, par un organe moteur électrique, pneumatique ou hydraulique qui agit directement sur l'arbre 13 parfois sous le contrôle d'un asservissement électronique permettant de régler, avec mémoire, le dossier par rapport à l'assise suivant la morphologie du passager occupant le siège.
When you want to operate the device other than by hand, you can also replace
this manual control, sometimes placed on the right, standing on the left of the seat, according to the free space provided for this control in the vehicle in question, by an electric, pneumatic or hydraulic drive member which acts directly on the shaft 13 sometimes under control an electronic servo-control making it possible to adjust, with memory, the backrest relative to the seat according to the morphology of the passenger occupying the seat.

Comme on peut s'en rendre compte à la fig. 1, lorsque l'on fait tourner l'arbre 13, la rotation entralne la rotation des cames 12 et 18 et, cette dernière, du fais de son excentration, provoque une réaction, en opposition, sur le palier circulaire consti- tué par la cage à rouleaux ouàaiguilles 11 entralnans ainsi l'engagement des dentures 8 et 21 à la partie supérieure de I'articulation en faisant ainsi rouler la couronne mobile 20 sur la couronne fixe 8, ce qui provoque le déplacement en avant ou en arrière de l'armature 24 du dossier du siège suivant le sens de rotation de l'arbre 13 et donc le réglage en continu entre une position maximum verticale et une position maximum inclinée du dossier du siège. As can be seen in fig. 1, when the shaft 13 is rotated, the rotation causes the rotation of the cams 12 and 18 and, the latter, due to its eccentricity, causes a reaction, in opposition, on the circular bearing constituted by the cage with rollers or needles 11 thus entering the teeth 8 and 21 at the upper part of the joint, thereby rolling the movable crown 20 on the fixed crown 8, which causes the forward or backward movement of the frame 24 of the seat back following the direction of rotation of the shaft 13 and therefore the continuous adjustment between a maximum vertical position and a maximum inclined position of the seat back.

Du fait de frottements des dentures l'une sur l'autre es de la réaction de la came 18 sur le palier constitué par la cage à aiguilles ou à rouleaux 11, on obtiens un blocage dans toutes les positions depuis la position verticale jusqu'à la position la plus inclinée, blocage qui est renforcé du fait du palier lisse constitué par la surface extérieure de la came 18 portant sur la périphérie du trou 20e percé dans la couronne mobile 20 pour lè passage de cette came. Due to friction of the teeth on each other due to the reaction of the cam 18 on the bearing constituted by the needle or roller cage 11, a blockage is obtained in all positions from the vertical position to the most inclined position, blocking which is reinforced due to the smooth bearing formed by the outer surface of the cam 18 bearing on the periphery of the hole 20e drilled in the movable ring 20 for the passage of this cam.

Comme on peut le voir à la fig î1la zone comprise entre la périphérie extérieure de la couronne mobile 20 et la périphérie intérieure de la cage 27 équivaut à l'excentration de la came 18 permettant le déplacement du flasque mobile 20. As can be seen in FIG. 1, the area between the outer periphery of the movable ring 20 and the inner periphery of the cage 27 is equivalent to the eccentricity of the cam 18 allowing the displacement of the movable flange 20.

Bien que ce disposiiif soit décrit dans ce qui précède pour le réglage en inclinaison d'un dossier de siège, on peut également l'utiliser pour le réglage de l'assiette d1un siège (réglage vertical avant, arrière ou avant et arrière de l'assise d'un siège).  Although this device is described in the above for adjusting the inclination of a seat back, it can also be used for adjusting the attitude of a seat (vertical adjustment front, rear or front and rear of the seat).
