Description
La présente invention concerne un dispositif d'articulation pour dossier démontable de siège arrière de véhicule. The present invention relates to a hinge device for a removable rear seat backrest of a vehicle.
On connait déjà des dossiers articulés sur le plancher d'un véhicule par l'intermédiaire d'axes solidaires de la partie inférieure du dossier et coopérant avec des paliers ou analogues fixés au plancher. There are already known files articulated on the floor of a vehicle by means of axes integral with the lower part of the file and cooperating with bearings or the like fixed to the floor.
Parmi les dossiers que l'on connait, certains ne sont ni démontables ni basculables ; d'autres sont basculables mais non démontables. Dans ce dernier cas, le point d'articulation du dossier par rapport au plancher peut se situer à une hauteur suffisante pour éviter un éventuel déboîtement de l'articulation lors du basculement du dossier, compte tenu de l'existence de l'assise restant en place. Or, dans cette situation particulière, la distance séparant le plan du plancher de celui du dossier une fois basculé est considérable, ce qui limite notablement l'espace de chargement. Among the files we know, some are neither removable nor tiltable; others are tiltable but not removable. In the latter case, the point of articulation of the backrest relative to the floor may be at a height sufficient to avoid possible dislocation of the articulation during the tilting of the backrest, taking into account the existence of the seat remaining in square. However, in this particular situation, the distance separating the plane of the floor from that of the backrest once tilted is considerable, which significantly limits the loading space.
Mais on connait également des dossiers de siège arrière basculables par rotation d'environ 900, l'assise étant escamotable également par rotation de celle-ci autour d'axes fixés sur sa partie inférieure, de manière à ce qu'elle vienne contre la partie arrière des dossiers des sièges avant. But there are also known rear seat backs that can be tilted by rotation of about 900, the seat also being retractable by rotation of the latter around axes fixed on its lower part, so that it comes against the part rear of the front seat backrests.
On connait encore des dossiers de siège arrière de véhicule qui sont démontables, mais cela au moyen d'un outillage particulier. We still know the rear seat backrests of the vehicle which are removable, but that by means of a particular tool.
La présente invention a pour but de résoudre le problème consistant à créer un dossier de siège arrière de véhicule, aisément démontable sans outillage particulier, permettant de diminuer les risques d'endommagement par déboîtement du système d'articulation, risques auxquels l'utilisateur peut être exposé à la suite de mauvaises manipulations. The aim of the present invention is to solve the problem of creating a rear seat backrest for a vehicle, easily removable without special tools, making it possible to reduce the risk of damage by dislodging the articulation system, risks to which the user may be exposed as a result of improper handling.
A cet effet, la présente invention a pour objet un dispositif d'articulation d'un dossier démontable de siège arrière de véhicule, du type reliant la partie inférieure du dossier au plancher du véhicule, grâce à des axes fixés aux armatures du dossier et coopérant respectivement avec des paliers ou analogues solidaires du plancher, ce dispositif étant caractérisé en ce que chaque palier est muni d'un moyen recevant l'axe et entraîné temporairement en rotation par celui-ci, ledit moyen et ledit axe étant conformés de telle manière que le dossier du siège doit être préalablement placé en position rabattue vers le plancher avant de pouvoir être démonté de ce plancher. To this end, the subject of the present invention is a device for articulating a removable backrest of a vehicle rear seat, of the type connecting the lower part of the backrest to the vehicle floor, by means of pins fixed to the armatures of the backrest and cooperating respectively with bearings or the like integral with the floor, this device being characterized in that each bearing is provided with means receiving the axis and temporarily driven in rotation by the latter, said means and said axis being shaped such that the seat back must first be placed in the folded position towards the floor before it can be removed from this floor.
Suivant une réalisation particulière de l'invention, le moyen précité est constitué par une bague fendue, dont la fente est susceptible de coïncider avec un passage ménagé dans le palier pour permettre l'introduction de l'axe dans ledit palier, ou bien sa sortie, après que le dossier ait été mis dans la position rabattue vers le plancher. According to a particular embodiment of the invention, the aforementioned means consists of a split ring, the slot of which is capable of coinciding with a passage formed in the bearing to allow the introduction of the axis into said bearing, or else its exit , after the backrest has been put in the folded down position towards the floor.
La bague fendue précitée est constituée d'un flasque fendu auquel sont associées au moins deux portées respectivement de part et d'autre de la fente, tandis qu'un anneau fendu monté librement en rotation sur ces deux portées, coopère avec le palier pour constituer une butée de limitation de la course de rotation de la bague. The aforementioned split ring consists of a split flange with which are associated at least two bearing surfaces respectively on either side of the slot, while a split ring mounted freely in rotation on these two bearing surfaces, cooperates with the bearing to constitute a stop for limiting the rotation stroke of the ring.
L'anneau est solidarisé au palier par l'intermédiaire d'une encoche ménagée sur son bord extérieur et coopérant avec un ergot ou analogue prévu sur le palier. The ring is secured to the bearing by means of a notch formed on its outer edge and cooperating with a lug or the like provided on the bearing.
Suivant une autre caractéristique de l'invention, les portées précitées coopèrent avec la forme de l'axe, de manière à permettre l'entrainement en rotation de la bague par l'axe, ou une rotation libre de ce dernier, dans la bague. According to another characteristic of the invention, the abovementioned bearings cooperate with the shape of the axis, so as to allow the rotation of the ring to be driven by the axis, or a free rotation of the latter, in the ring.
L'une des portées est formée de deux demi-portées, coopérant avec l'anneau lors de la rotation de la bague par rapport à l'anneau dans un sens ou dans 1 ' autre. One of the bearing surfaces is formed by two half-bearing surfaces, cooperating with the ring during the rotation of the ring relative to the ring in one direction or in the other.
Selon encore une autre caractéristique de l'invention, les portées précitées comportent au moins une languette destinée à coopérer avec au moins une encoche ménagée sur l'anneau. According to yet another characteristic of the invention, the abovementioned bearing surfaces comprise at least one tongue intended to cooperate with at least one notch formed on the ring.
On précisera que les portées comportent des bords libres formant clips, permettant le clippage de la bague dans le palier et la retenue de l'anneau sur la bague. It will be noted that the bearing surfaces have free edges forming clips, allowing the clipping of the ring in the bearing and the retaining of the ring on the ring.
Suivant encore une autre caractéristique, l'axe du dossier de siège comporte deux méplats opposés et parallèles et se termine par une rondelle d'arrêt. According to yet another characteristic, the axis of the seat back has two opposite and parallel flats and ends with a locking washer.
On précisera encore que les paliers précités peuvent présenter une forme de coupelle ou de chape. It will also be specified that the abovementioned bearings may have a shape of cup or yoke.

- Figures 9, 10, 11, 12 and 13 illustrate in section the operation of the articulation device of the invention for various positions of the seat back and namely an intermediate position for inserting the back (Figure 9), a backrest service position (Figure 10), an intermediate position of the backrest and for which it remains integral by its articulation with the seat cushion (Figure 11), a completely folded position of the backrest towards the seat cushion after retraction of this seat (Figure 12) and a raised position of the back allowing the separation of the back of the seat (Figure 13).
On voit sur la figure 1, deux dossiers 1, 11 de siège arrière d'un véhicule, qui sont constitués principalement chacun, d'une armature 2, 12 sur la partie inférieure desquelles ont été fixés des axes 7, 9, se terminant par une rondelle d'arrêt 8. Ces dossiers 1, 11 sont articulés à la structure du véhicule (non représenté) par l'intermédiaire de paliers P qui sont solidaires du plancher ou du côté de la caisse. We see in Figure 1, two records 1, 11 of the rear seat of a vehicle, which consist mainly each of a frame 2, 12 on the lower part of which have been fixed axes 7, 9, ending with a locking washer 8. These files 1, 11 are articulated to the structure of the vehicle (not shown) by means of bearings P which are integral with the floor or on the side of the body.
Suivant une réalisation particulière de l'invention, les paliers P revêtent la forme d'une coupelle 5 lorsqu'ils relient l'extrémité inférieure et extérieure d'un dossier 1, 11 au côté de la caisse, et d'une chape 6 pouvant recevoir deux axes lorsqu'ils relient au plancher deux axes en regard 7, 9 de deux dossiers 1, 11 disposés côte à côte. Les chape 6 et coupelle 5 comportent chacune d'une part, au moins une ouverture 60, 62, 50 destinée à recevoir un axe 7, 9, et d'autre part un passage 61, 63, 51 prévu au niveau de la partie supérieure de l'ouverture 60, 50, 62, et permettant l'introduction latérale de l'axe 7, 9 dans chaque chape 6 ou coupelle 5, ainsi que le passage de la rondelle d'arrêt 8 de l'axe. According to a particular embodiment of the invention, the bearings P take the form of a cup 5 when they connect the lower and outer end of a backrest 1, 11 to the side of the body, and of a yoke 6 which can receive two axes when they connect to the floor two opposite axes 7, 9 of two files 1, 11 arranged side by side. The yoke 6 and cup 5 each comprise on the one hand, at least one opening 60, 62, 50 intended to receive an axis 7, 9, and on the other hand a passage 61, 63, 51 provided at the level of the upper part of the opening 60, 50, 62, and allowing the lateral introduction of the axis 7, 9 into each yoke 6 or cup 5, as well as the passage of the stop washer 8 of the axis.
Afin d'éviter que l'axe 7, 9 ne se libère inconsidèrement des paliers P, une bague 3, 4 comportant une fente 30, 40 destinée au passage d'un axe 7, 9 permettra lorsqu'elle est entraînée en rotation dans le palier P par ledit axe 7, 9, l'ouverture ou la fermeture du passage latéral 61, 63, 51 de cet axe 7, 9 dans ledit palier P. La structure et le fonctionnement de la bague 3, 4 seront décrits plus précisément dans ce qui va suivre. In order to prevent the axis 7, 9 from being thoughtlessly released from the bearings P, a ring 3, 4 having a slot 30, 40 intended for the passage of an axis 7, 9 will allow when it is rotated in the bearing P by said axis 7, 9, the opening or closing of the lateral passage 61, 63, 51 of this axis 7, 9 in said bearing P. The structure and operation of the ring 3, 4 will be described more precisely in what will follow.
Les bagues 3, 4 dites droite et gauche sont différenciées pour les raisons qui seront exposées ultérieurement. The rings 3, 4 called right and left are differentiated for the reasons which will be explained later.
Sur les figures 2 et 3, l'axe 7, 9 terminé par une rondelle 8, est fixé à l'armature 2 d'un dossier 1 par l'intermédiaire d'un support 10, et présente une section rectangulaire. On voit, que les ouvertures 60, 62, 50 de la chape 6 et de la coupelle conique 5 présentent une forme de canon cylindrique ; ces ouvertures cylindriques 60, 62, 50 sont situées pour la chape sur chacune des ailes du U qu'elle forme ; les passages 63, 61, 51 permettant l'introduction latérale de l'axe 7, 9 et de la rondelle 8, se trouvent dans le prolongement des ouvertures 60, 62, 50. In FIGS. 2 and 3, the axis 7, 9 terminated by a washer 8, is fixed to the frame 2 of a backrest 1 by means of a support 10, and has a rectangular section. It can be seen that the openings 60, 62, 50 of the yoke 6 and of the conical cup 5 have the shape of a cylindrical barrel; these cylindrical openings 60, 62, 50 are located for the yoke on each of the wings of the U that it forms; the passages 63, 61, 51 allowing the lateral introduction of the axis 7, 9 and the washer 8, are located in the extension of the openings 60, 62, 50.
Les bagues fendues 3, 4 réalisées en un matériau souple, sont constituées d'un flasque fendu 31, 41 en forme d'anneau, sur la circonférence intérieure duquel s'étendent, perpendiculairement à sa surface, et de part et d'autre de la fente 30, 40, des portées 32, 42 dont les bords libres 33, 43 forment des clips. Les bagues 3, 4 sont destinées à être introduites axialement dans l'une des ouvertures cylindriques de la chape 6 ou de la coupelle 5, les deux bords de la fente 30, 40 se rapprochant au fur et à mesure de leur introduction, et le maintien en position des bagues 3, 4 étant obtenu par clippage des bords libres 33, 43 des portées 32,42 sur les bords de l'ouverture 60, 62, 50 des paliers P. The split rings 3, 4 made of a flexible material, consist of a split flange 31, 41 in the form of a ring, on the inner circumference of which extend, perpendicular to its surface, and on either side of the slot 30, 40, the bearing surfaces 32, 42 whose free edges 33, 43 form clips. The rings 3, 4 are intended to be introduced axially into one of the cylindrical openings of the yoke 6 or of the cup 5, the two edges of the slot 30, 40 approaching as they are introduced, and the holding the rings 3, 4 in position by clipping the free edges 33, 43 of the bearing surfaces 32, 42 on the edges of the opening 60, 62, 50 of the bearings P.
Un anneau 15 est monté librement en rotation sur les portées 32, 42 de chaque bague 3, 4, et sera solidarisé au palier P après mise en place de chaque bague 3, 4, au moyen d'une encoche (non visible sur les figures 2 et 3, mais repérée en 153 sur la figure 6) ménagée sur son bord extérieur, et coopérant avec un ergot 600, 500 prévu sur le bord de l'ouverture 60, 62, 50 de la chape 6 ou de la coupelle 5. A ring 15 is mounted freely in rotation on the bearing surfaces 32, 42 of each ring 3, 4, and will be secured to the bearing P after positioning of each ring 3, 4, by means of a notch (not visible in the figures 2 and 3, but identified at 153 in FIG. 6) formed on its outer edge, and cooperating with a lug 600, 500 provided on the edge of the opening 60, 62, 50 of the yoke 6 or of the cup 5.
La figure 4 montre les formes et positions des portées 42 d'une bague 4 dite gauche ; c'est-à-dire dont lesdites portées 42 sont orientées du côté gauche du véhicule ; ces portées 42 sont au nombre de deux dont l'une située à gauche de la fente est formée de deux demi-portées 420, 421 ; la demi-portée 420 revêt la forme, si l'on exclut les rebords 43, d'une partie d'anneau, sa courbure intérieure prolongeant le bord de l'ouverture circulaire de la bague 4, alors que l'autre demi-portée 421 ainsi que la deuxième portée 422 située à droite de la fente 40, ont également la forme d'une partie d'anneau, leur courbure extérieure prolongeant le bord de l'ouverture de la bague 3, 4. FIG. 4 shows the shapes and positions of the bearings 42 of a so-called left ring 4; that is to say, whose said scopes 42 are oriented on the left side of the vehicle; these spans 42 are two in number, one of which located to the left of the slot is formed by two half-spans 420, 421; the half-span 420 takes the form, if the edges 43 are excluded, of a ring part, its internal curvature extending the edge of the circular opening of the ring 4, while the other half-span 421 as well as the second bearing 422 situated to the right of the slot 40, also have the shape of a ring part, their external curvature extending the edge of the opening of the ring 3, 4.
Sur les figures 5 et 6, l'anneau 15 précité est pourvu sur sa périphérie, d'un élément en saillie 150 (figure 8) dont l'un des bords latéraux 151 est destiné à réaliser une butée de limitation de la course de rotation de la bague 4, en venant en contact avec le bord libre du rebord 43 de la demi-portée 421. Ce bord libre est pourvu en outre d'une languette 423 destinée à venir s'insérer dans une encoche 152 ménagée dans l'élément en saillie 150, dans le prolongement de la périphérie intérieure de l'anneau 15, afin de réaliser un clippage de faible résistance, comme ceci apparalt sur la figure 5. Ce clippage permet de conserver à l'ensemble une position ouverte avec l'entrée libre lors de son transport, et de son montage.On voit en outre (figure 6) que l'élément en saillie 150 comporte une encoche 153 précédemment mentionnée et destinée à coopérer avec un ergot (en 600 et 500 sur les figures 2 et 3) et situé sur le bord de l'ouverture du palier pour assurer le blocage de l'anneau 15 dans le palier. In FIGS. 5 and 6, the aforementioned ring 15 is provided on its periphery with a projecting element 150 (FIG. 8) one of the lateral edges 151 of which is intended to produce a stop for limiting the rotational stroke of the ring 4, coming into contact with the free edge of the rim 43 of the half-span 421. This free edge is further provided with a tongue 423 intended to be inserted in a notch 152 formed in the element protruding 150, in the extension of the inner periphery of the ring 15, in order to carry out a clipping of low resistance, as this appears on FIG. 5. This clipping makes it possible to preserve the whole an open position with the entry free during transport and assembly. We can also see (Figure 6) that the protruding element 150 has a notch 153 previously mentioned and intended to cooperate with a lug (at 600 and 500 in Figures 2 and 3 ) and located on the edge of the bearing opening for a Ensure that the ring 15 is blocked in the bearing.
On peut remarquer sur la figure 7 que les rebords des portées formant clips 43 participent au maintien de l'anneau 15 en position autour de la bague 4. It can be seen in FIG. 7 that the edges of the bearing surfaces forming clips 43 participate in maintaining the ring 15 in position around the ring 4.
On expliquera ci-après le fonctionnement du dispositif d'articulation qui vient d'être décrit en s'aidant des figures 9 à 13. The operation of the articulation device which has just been described will be explained below with the aid of FIGS. 9 to 13.
Sur la figure 9 on voit la mise en place du dossier 1, l'assise 100 ayant été basculée vers l'avant du véhicule jusqu'à venir contre le dossier du siège avant. Dans cette configuration, on voit la bague 4 dite gauche et son anneau associé 15 qui est mis en place dans l'ouverture 50 de la coupelle 5, l'anneau 15 solidaire de la coupelle 5 se bloquant contre l'ergot 500 (figure 3) de ladite ouverture ce qui permet l'indexage et le détrompage de la bague 4. Le même montage est réalisé pour les bagues 3 dites droites, dans l'ouverture de la chape 6. Les fentes de la bagues 4 et de l'anneau 15 ainsi que le passage 51 dans la coupelle 5 se trouvant en colncidence, on procède alors à l'introduction latérale de l'axe 9. Les deux méplats 90, 91 de ce dernier viennent en contact avec respectivement les faces en regard de la portée 422 et de la demi-portée 421.Le dossier 1 sera alors basculé vers l'arrière du véhicule, jusqu'à ce qu'il prenne la position de service. Le basculement du dossier 1 va entraîner l'axe 9 en rotation, lequel entravera la bague 4 à l'intérieur de l'anneau 15 et du palier P, comme on le voit sur la figure 10. Le basculement du dossier 1 est limité d'une part, par un système de verrouillage 101 prévu à sa partie supérieure, d'autre part par la mise en contact de l'extrémité 155 de l'anneau 15 avec l'extrémité de la demi-portée 420 qui obstrue à cet instant le passage du palier P.Lors du basculement du dossier 1 vers l'avant du véhicule dans le but de le retirer, l'assise 100 ayant été replacée entre temps, l'axe 9 va tourner librement en rotation dans la bague 4 jusqu'à ce que les méplats 90, 91 viennent en contact respectivement avec les faces en regard de la portée 422 et de la demi-portée 421 (figure 11).. In Figure 9 we see the establishment of the backrest 1, the seat 100 having been tilted towards the front of the vehicle until it comes against the backrest of the front seat. In this configuration, we see the ring 4 called left and its associated ring 15 which is placed in the opening 50 of the cup 5, the ring 15 secured to the cup 5 blocking against the lug 500 (Figure 3 ) of said opening which allows the indexing and the coding of the ring 4. The same assembly is carried out for the rings 3 said straight, in the opening of the yoke 6. The slots of the rings 4 and of the ring 15 as well as the passage 51 in the cup 5 being in coincidence, one then proceeds to the lateral introduction of the axis 9. The two flats 90, 91 of the latter come into contact with the opposite faces of the bearing respectively 422 and the half-span 421. The backrest 1 will then be tilted towards the rear of the vehicle, until it takes the service position. The tilting of the backrest 1 will cause the axis 9 to rotate, which will hamper the ring 4 inside the ring 15 and the bearing P, as can be seen in FIG. 10. The tilting of the backrest 1 is limited d on the one hand, by a locking system 101 provided at its upper part, on the other hand by bringing the end 155 of the ring 15 into contact with the end of the half-span 420 which obstructs at this instant the passage of the bearing P. During the tilting of the backrest 1 towards the front of the vehicle in order to remove it, the seat 100 having been replaced in the meantime, the axis 9 will rotate freely in rotation in the ring 4 until that the flats 90, 91 come into contact respectively with the opposite faces of the bearing 422 and the half-bearing 421 (FIG. 11).
Dans cette configuration la demi-portée 420 bloque toujours le passage 51 du palier P ; pour libérer ce passage, il est donc nécessaire d'entraîner la bague 4 en rotation par un basculement du dossier 1 vers l'avant jusqu'à ce que ce dernier prenne la position de l'assise 100; il est donc indispensable pour en arriver à cette fin de retirer cette assise 100 ; comme on le voit sur la figure 12. In this configuration, the half-span 420 always blocks the passage 51 of the bearing P; to free this passage, it is therefore necessary to drive the ring 4 in rotation by tilting the backrest 1 forward until the latter takes the position of the seat 100; it is therefore essential to arrive at this end to remove this seat 100; as seen in Figure 12.
Dans cette configuration le passage 51 de l'axe 9 est dégagé, la bague 4 est en butée au niveau de la demi-portée 421 contre l'élément en saillie 150 de l'anneau 15, la languette (423, figure 4) de la bague 4 étant clippée dans l'encoche (152, figure 6) de l'anneau 15. I1 suffira alors pour procéder au retrait du dossier 1 de basculer celui-ci vers l'arrière jusqu'à ce que les méplats 90, 91 de l'axe 9 se trouvent dans le prolongement des bords de la fente 51 de passage de l'axe 9 ; ce qui est bien visible sur la figure 13 ; on se retrouve alors dans la configuration de départ correspondant à la position d'insertion du dossier visible sur la figure 9.On peut noter qu'au cours de toutes ces manipulations l'axe 9 ne se trouve jamais en contact direct avec le palier ; les portées de la bague 3, 4, ou bien l'anneau 15 étant toujours interposées entre l'axe et le palier P, ce qui évite les bruits indésirables produits par le contact métal contre métal. In this configuration the passage 51 of the axis 9 is cleared, the ring 4 is in abutment at the level of the half-bearing 421 against the projecting element 150 of the ring 15, the tongue (423, FIG. 4) of the ring 4 being clipped into the notch (152, FIG. 6) of the ring 15. I1 will then suffice to proceed with the removal of the backrest 1 to tilt the latter backwards until the flats 90, 91 of the axis 9 are in the extension of the edges of the slot 51 for passage of the axis 9; which is clearly visible in Figure 13; we then find ourselves in the initial configuration corresponding to the position of insertion of the backrest visible in FIG. 9. We can note that during all these manipulations the axis 9 is never in direct contact with the bearing; the bearing surfaces of the ring 3, 4, or else the ring 15 is always interposed between the axis and the bearing P, which avoids the undesirable noises produced by the metal against metal contact.
On a donc réalisé suivant l'invention, un dispositif d'articulation de dossier de siège arrière de véhicule, qui rend nécessaire le basculement complet du dossier vers le plancher pour procéder à son retrait, ce qui évite les retraits intempestifs sous l'effet d'une manoeuvre de celui-ci alors que l'assise n'est pas elle-même basculée. Autrement dit, grâce à la présente invention on évite avantageusement les déboitements intempestifs ou l'endommagement de l'articulation. We have therefore produced according to the invention, a rear seat backrest articulation device of the vehicle, which makes it necessary to tilt the backrest completely to the floor to proceed with its removal, which avoids untimely withdrawals under the effect of 'a maneuver thereof while the seat is not itself tilted. In other words, thanks to the present invention advantageously avoids untimely dislocations or damage to the joint.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit. On the contrary, the invention includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
