Abstract
Description
Dans la pratique courante, les sièges pour véhicules, et en particulier pour automobiles sont composés d'une armature d'assise et d'une armature de dossier que l'on rend solidaires l'une de l'autre par différents moyens connus. Dans certains cas il est possible de monter, entre l'armature d'assise et l'armature de dossier, des mécanismes de positionnement variable du dossier par rapport à l'assise. Le garnissage du siège est fait ensuite. In current practice, the seats for vehicles, and in particular for cars, are composed of a seat frame and a back frame which are made integral with one another by various known means. In certain cases it is possible to mount, between the seat frame and the back frame, mechanisms for variable positioning of the backrest relative to the seat. The seat upholstery is then made.
Cela est vrai également pour les banquettes que l'on utilise le plus souvent à l'arrière du véhicule mais lorsque les deux armatures sont réunies, l'ensemble est très encombrant et lourd et, de ce fait, le montage dans l'habitacle d'un véhicule est toujours fastidieux et nécessite, le plus souvent, l'emploi de deux intervenants. This is also true for the benches that are most often used at the rear of the vehicle, but when the two frames are combined, the assembly is very bulky and heavy and, therefore, the mounting in the passenger compartment. 'a vehicle is always tedious and most often requires the employment of two workers.
On a cherché à automatiser le montage des sièges mais, du fait de l'encombrement et du poids de chacun de ceux-ci, il est nécessaire d'utiliser des moyens complexes pour contourner les difficultés d'introduction dans l'habitacle de ces sièges surtout lorsqu'ils sont équipés d'un appui-tête. Attempts have been made to automate the mounting of the seats but, owing to the size and the weight of each of them, it is necessary to use complex means to circumvent the difficulties of introduction into the passenger compartment of these seats. especially when equipped with a headrest.
On connaît déjà et en particulier par le
FR-A-8814698 un dispositif permettant la réalisation séparée de l'armature du dossier de l'armature de l'assise qui sera montée seule sur le plancher du véhicule en automatique dans un premier poste de montage de la chaîne. Puis dans un deuxième poste de montage de cette même chaine, on peut positionner l'armature du dossier sur l'armature de l'assise soit manuellement, soit automatiquement. I1 est également possible dans l'art antérieur de réaliser la fixation de l'armature du dossier sur l'armature de l'assise manuellement et sans outil en utilisant des butées prépositionnées.We already know and in particular by the
FR-A-8814698 a device for the separate production of the back frame of the seat frame which will be mounted alone on the vehicle floor automatically in a first assembly station of the chain. Then in a second assembly station of this same chain, the back frame can be positioned on the seat frame either manually or automatically. I1 is also possible in the prior art to fix the back frame on the seat frame manually and without tools using pre-positioned stops.
Cependant des difficultés ont été rencontrées en particulier, il se produit des jeux qui font que le dossier n'est pas complètement fixe, ce qui donne un sentiment d'insécurité aux passagers. However, difficulties have been encountered in particular, there are games which cause the backrest to not be completely fixed, which gives passengers a feeling of insecurity.
La présente invention remédie à ces inconvénients en créant un dispositif de positionnement d'assemblage et de blocage monté en automatique, d'une armature de dossier sur une armature d'assise de siège avec une complète sécurité et un blocage parfait des deux éléments l'un par rapport à l'autre, sans les inconvénients mentionnés ci-dessus. The present invention overcomes these drawbacks by creating an assembly positioning and locking device mounted automatically, of a back frame on a seat seat frame with complete security and perfect blocking of the two elements. one over the other, without the disadvantages mentioned above.
Conformément à l'invention les boîtiers comportent à deux emplacements superposés et alignés, des renflements destinés chacun à contenir un galet strié présentant en leur centre un tourillon central permettant l'accrochage d'une des extrémités d'un ressort de rappel dont l'autre extrémité est fixe sur un redent prévu à la partie inférieure des boîtiers, ces boîtiers assemblés recevant par introduction verticale les extrémités inférieures de l'armature de l'assise constituées par des lames de forme sensiblement trapézodale et présentant sur leur grandes faces opposées des stries coopérant avec les galets. In accordance with the invention, the housings have, at two superimposed and aligned locations, bulges each intended to contain a striated roller having in their center a central pin allowing the attachment of one of the ends of a return spring, the other of which end is fixed on a recess provided at the lower part of the housings, these assembled housings receiving by vertical introduction the lower ends of the seat frame constituted by blades of substantially trapezoidal shape and having on their large opposite faces co-operating grooves with the pebbles.
Suivant une autre caractéristique de l'invention, les ressorts sont des ressorts de traction. According to another characteristic of the invention, the springs are tension springs.
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, aux dessins annexés. An embodiment of the object of the invention is shown, by way of example, in the accompanying drawings.
La fig. 1 montre de face, la zone de jonction de l'armature du dossier sur l'armature d'assise étant entendu que l'on n'a représenté qu'un côté du siège pour faciliter la compréhension. Fig. 1 shows from the front, the junction area of the back frame on the seat frame, it being understood that only one side of the seat has been shown to facilitate understanding.
La fig. 2 est une coupe, à grande échelle, suivant la ligne II-II de la fig. 1. Fig. 2 is a section, on a large scale, along the line II-II of FIG. 1.
La fig. 3 est une coupe suivant la ligne III-III de la fig. 1. Fig. 3 is a section along line III-III of FIG. 1.
A la fig. 1, on a représenté d'une manière schématique l'armature 100 du dossier du siège considéré, cette armature n'étant figurée que par sa partie inférieure terminale. La partie inférieure solidaire de l'assise est une lame 101 plane presque trapézoldale (voir fig. 2 et 3) qui présente sur ses faces opposées 101a, 101b des crantages 102. In fig. 1, there is shown schematically the frame 100 of the seat back in question, this frame being only shown by its lower terminal part. The lower part integral with the seat is a planar blade 101 almost trapezoidal (see FIGS. 2 and 3) which has notches 102 on its opposite faces 101a, 101b.
L'armature 100 du dossier du siège porte un boîtier de forme sensiblement trapézoldale 104 constitué par deux pièces 105, 106 réunies par soudure et/ou agrafées aux points 107, 108, 109. Ce boîtier présente comme cela est très visible i la fig. 2, deux zones renflées 104a, l'une a la partie supérieure et, l'autre n sa partie inférieure (voir fig. 1) ces deux zones renflées étant alignées l'une sous l'autre. Les bords du boîtier comportent des redents 110 pour assurer la fixation des ressorts spiraux 111. L'extrémité libre lila de chaque ressort 111 est accrochée sur un tourillon 112 central de chaque galet strié 113 dont les stries 114 coopèrent avec les stries des crantages 102 de l'armature 101 de l'assise (voir fig. 2).Les ressorts 111 tendent du fait de leur disposition t abaisser les galets 113 vers le bas. I1 est signalé que les extrémités lîla des ressorts 111 traversent la zone renflée 104a de chaque boîtier 104 par des ouvertures 116. The frame 100 of the seat back carries a box of substantially trapezoidal shape 104 consisting of two pieces 105, 106 joined by welding and / or stapled at points 107, 108, 109. This box has, as can be seen in FIG. 2, two swollen zones 104a, one at the upper part and the other at its lower part (see FIG. 1) these two swollen zones being aligned one under the other. The edges of the housing have redents 110 to secure the spiral springs 111. The lilac free end of each spring 111 is hung on a central pin 112 of each striated roller 113 whose ridges 114 cooperate with the ridges of the notches 102 of the frame 101 of the seat (see fig. 2). The springs 111 tend because of their arrangement to lower the rollers 113 downwards. It is pointed out that the ends of the springs 111 pass through the bulged area 104a of each box 104 through openings 116.
I1 y a lieu de remarquer également a la fig. 2, qu'un seul ressort est représenté pour le galet strié 113, car l'autre galet strié 113, du côté gauche du dessin, se trouve placé en arrière et n'est donc pas visible. Un montage de l'ensemble s'effectue de la façon suivante : lorsqu'un boîtier 104 est en place sur l'un des côté de l'armature de dossier d'un siège (voir fig. It should also be noted in FIG. 2, only one spring is shown for the striated roller 113, because the other striated roller 113, on the left side of the drawing, is placed behind and is therefore not visible. The assembly is carried out as follows: when a housing 104 is in place on one of the sides of the seat back frame of a seat (see fig.
1) et que l'autre côté de l'armature de ce siège comporte également le même boîtier 104 symétriquement disposé, il suffit d'engager l'extrémité inférieure triangulaire de l'armature 100 du dossier de façon que l'extrémité d'armature 101 de l'assise vienne en butée sur la partie intérieure du boîtier 104. Les galets striés 113 en coopérant avec les crantages 102 de l'armature de l'assise 101 bloquent alors cette dernière du fait que les ressorts 111 tendent à faire descendre les galets 113 vers le bas en bloquant ainsi fermement l'armature du dossier sur l'armature de l'assise.1) and that the other side of the frame of this seat also has the same symmetrically arranged housing 104, it suffices to engage the triangular lower end of the frame 100 of the backrest so that the frame end 101 of the seat comes into abutment on the inner part of the housing 104. The striated rollers 113 by cooperating with the notches 102 of the frame of the seat 101 then block the latter because the springs 111 tend to lower the rollers 113 downwards, thus firmly locking the back frame on the seat frame.
Pour le démontage du dossier il suffit de dégager les galets 113 en les ramenant vers le haut dans la zone renflée 104a pour libérer les crantages 102 des stries 114 des galets 113. Le dossier est alors libre. For dismantling the backrest, it suffices to disengage the rollers 113 by bringing them upwards in the bulged area 104a to release the notches 102 from the ridges 114 of the rollers 113. The backrest is then free.
Cette construction permet un montage rapide et sûr du dossier sur l'assise et ce travail peut donc être effectué sur machine automatique. De plus la conception simple mais efficace du coincement par galets striés assure un blocage sans jeu et une grande sécurité de la liaison du dossier avec le siège, ce d'autant plus que les renflements 104a sont à une distance suffisante l'un de l'autre. This construction allows quick and safe mounting of the backrest on the seat and this work can therefore be carried out on an automatic machine. In addition, the simple but effective design of wedging by ridged rollers ensures blockage without play and great security in the connection of the backrest with the seat, all the more so that the bulges 104a are at a sufficient distance from one of the other.
