Description

DISPOSITIF DE MAINTIEN EN DEVERROUILLAGE DE L'ARTICULATION POUR SIEGE INCLINABLE DE VEHICULE DEVICE FOR UNLOCKING THE JOINT FOR A TILTING SEAT OF A VEHICLE
La présente invention concerne un siège de véhicule automobile dont le dossier est articulé sur l'assise, l'inclinaison du dossier par rapport à l'assise étant réglable et verrouillable dans certaines plages angulaires, grâce à un mécanisme spécial communément appelé « articulation ».The present invention relates to a motor vehicle seat whose backrest is articulated on the seat, the inclination of the backrest relative to the seat being adjustable and lockable in certain angular ranges, thanks to a special mechanism commonly called "articulation".
Le principe général de l'articulation de siège est connue depuis longtemps, par exemple par les documents FR 2 599 684 ou EP 0 770 514. Il repose sur l'engrènement, avec une couronne dentée, de trois grains espacés angulairement de 120°, cet engrènement étant débrayable grâce à un axe de l'articulation actionné par une poignée. En position de débrayage, les grains se rapprochent du centre de l'articulation et n'engrènent plus dans la couronne dentée.The general principle of the seat joint has been known for a long time, for example by the documents FR 2 599 684 or EP 0 770 514. It is based on meshing, with a ring gear, of three grains angularly spaced apart by 120 °, this meshing being disengageable thanks to an axis of the articulation actuated by a handle. In the disengaged position, the grains are closer to the center of the articulation and no longer mesh with the ring gear.
Comme l'inclinaison réglable n'est utile que sur une plage angulaire plus limitée que 120°, et qu'il est opportun par ailleurs de ne pas pouvoir verrouiller le siège en dehors de cette plage angulaire, il est connu, par exemple par le document FR 2 659 604, de prévoir sur la couronne dentée de l'articulation des secteurs non crantés, où les grains ne pourront donc pas engrener. Par exemple, il est connu de répartir chaque secteur de 120° de la couronne dentée en un secteur effectivement cranté de 75° et un secteur lisse de 45°. Le secteur cranté supérieur se partage de part et d'autre de la verticale, par exemple entre 65° vers l'arrière et 10° vers l'avant ; ce secteur cranté est donc suivi vers l'avant du secteur lisse de 45°, lui-même suivi, à un inclinaison de 35° sur l'horizontale, du début du secteur cranté suivant. II est souhaitable dans certains véhicules de pouvoir escamoter le siège en amenant le dossier en tablette vers l'avant, à l'horizontale. L'utilisateur doit alors manœuvrer la poignée de l'axe d'articulation et simultanément faire pivoter le dossier vers l'avant ; un fois que l'inclinaison de celui-ci le fait passer dans les secteurs non crantés de l'articulation, c'est-à-dire entre 10° et 55° au-delà de la verticale, l'utilisateur peut lâcher la poignée car le verrouillage du fauteuil n'est plus possible. Mais ce verrouillage redevient possible (au-delà de 55° dans l'exemple donné) avant d'atteindre l'horizontale, si bien que l'utilisateur doit à nouveau actionner la poignée de manœuvre dans la dernière partie de l'opération de mise en tablette, pour éviter le verrouillage du fauteuil avant d'atteindre la position d'escamotage. Par ailleurs, il est difficile pour l'utilisateur d'estimer avec exactitude cette position horizontale, de sorte que le dossier peut finalement être immobilisé dans une position qui n'est pas la position absolument idéale. Le but de l'invention est de remédier à cette difficulté et de permettre à l'utilisateur de relâcher la poignée de manœuvre lorsqu'il escamote le dossier, au moins sur toute la partie finale de la manœuvre et de permettre le verrouillage exactement dans la position désirée pour l'escamotage, en principe la position horizontale.Since the adjustable inclination is only useful over a more limited angular range than 120 °, and it is also advisable not to be able to lock the seat outside this angular range, it is known, for example by the document FR 2 659 604, to provide on the toothed crown of the joint non-toothed sectors, where the grains will not be able to mesh. For example, it is known to distribute each sector of 120 ° of the ring gear in a sector actually notched 75 ° and a smooth sector of 45 °. The upper notched sector is shared on either side of the vertical, for example between 65 ° to the rear and 10 ° to the front; this notched sector is therefore followed towards the front of the smooth sector of 45 °, itself followed, at an inclination of 35 ° on the horizontal, the beginning of the next notched sector. It is desirable in some vehicles to be able to retract the seat by bringing the file back to the shelf, horizontally. The user must then operate the handle of the hinge pin and simultaneously rotate the folder forward; once the inclination of the latter makes it pass into the non-serrated areas of the joint, that is to say between 10 ° and 55 ° beyond the vertical, the user can let go of the handle because locking the chair is no longer possible. But this lock becomes possible (beyond 55 ° in the example given) before reaching the horizontal, so that the user must again operate the handle in the last part of the operation of setting tablet, to prevent locking the chair before reaching the retracted position. Moreover, it is difficult for the user to accurately estimate this horizontal position, so that the file can finally be locked in a position that is not the absolutely ideal position. The object of the invention is to overcome this difficulty and to allow the user to release the handle when he retracts the backrest, at least over the entire final part of the maneuver and allow the lock exactly in the desired position for retraction, in principle the horizontal position.
Ce but est atteint selon l'invention grâce à un dispositif de maintien en dé verrouillage d'une articulation de siège comprenant un mécanisme de verrouillage débrayable par la rotation d'un axe de l'articulation, caractérisé en ce que le dispositif comprend une came liée au dossier dont le profil est destiné à agir sur des moyens d'entraînement en rotation forcée de l'axe d'articulation à partir d'un premier angle d'inclinaison du dossier vers l'avant et à cesser d'agir sur lesdits moyens d'entraînement à partir d'un second angle d'inclinaison vers l'avant. Ainsi l'utilisateur peut-il relâcher la poignée de manœuvre dès qu'il a passé le premier angle, et le dossier s'inclinera sans verrouillage jusqu'au second angle.This object is achieved according to the invention by means of a locking device for locking a seat hinge comprising a locking mechanism disengageable by the rotation of an axis of the hinge, characterized in that the device comprises a cam linked to the backrest, the profile of which is intended to act on means of driving in forced rotation of the hinge pin from a first angle of inclination of the backrest forward and to stop acting on said driving means from a second inclination angle forward. Thus the user can release the handle as soon as he has passed the first angle, and the backrest will tilt without locking to the second angle.
Le premier angle peut être choisi inférieur ou égal à 10°, ou sinon, il peut être choisi à une valeur quelconque égale ou supérieure à l'entrée dans le secteur non cranté de l'articulation (mais inférieure à l'entrée dans le secteur cranté suivant). Le second angle est avantageusement choisi égal à 90° pour garantir l'escamotage précis à l'horizontale. De cette manière, le dossier se place directement en fin de course vers l'avant dans la position d'escamotage idéale, sans que l'utilisateur n'ait eu à reprendre la poignée de manœuvre.The first angle may be chosen to be less than or equal to 10 °, or otherwise it may be chosen at any value equal to or greater than the entry into the notched area of the joint (but less than the entry into the sector notched next). The second angle is advantageously chosen equal to 90 ° to ensure accurate retraction horizontally. In this way, the folder is placed directly at the end of the race forwards in the ideal retracted position, without the user having to resume the handle.
Le dispositif de l'invention et les moyens d'entraînement en rotation forcés sont extérieurs à l'articulation de sorte qu'on peut utiliser une articulation classique et y adapter les moyens de l'invention.The device of the invention and the forced rotation drive means are external to the joint so that a conventional joint can be used and adapt the means of the invention.
Selon un mode de réalisation, les moyens d'entraînement en rotation forcée comprennent un jeu de biellettes dont l'extrémité de l'une est liée en rotation à l'axe de l'articulation, et dont l'extrémité de l'autre est liée à un organe poussé par la came du dispositif.According to one embodiment, the forced rotation drive means comprise a set of rods whose end of one is rotatably connected to the axis of the articulation, and whose end of the other is linked to an organ pushed by the cam of the device.
L'organe poussé par la came circule avantageusement dans une lumière de guidage. Celle-ci est formée dans la paroi d'une pièce de guidage solidarisée au siège ; cette paroi peut être prévue à une légère distance de la surface d'application au siège pour loger entre elle et le siège le jeu de biellettes. La pièce de guidage peut comporter une surface tourillonnant dans une pièce solidarisée au dossier et venant coiffer la pièce de guidage au voisinage de l'axe de l'articulation. Cette pièce forme avantageusement ladite came au niveau d'une patte.The member pushed by the cam advantageously circulates in a guiding light. This is formed in the wall of a guide piece secured to the seat; this wall may be provided at a slight distance from the application surface to the seat to house between it and the seat the set of rods. The guide piece may comprise a journal surface in a part secured to the backrest and to cap the guide piece in the vicinity of the axis of the joint. This piece advantageously forms said cam at a leg.
D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante d'un exemple de réalisation. Il sera fait référence aux dessins annexés sur lesquels :Other features and advantages of the invention will emerge from the following description of an exemplary embodiment. Reference will be made to the accompanying drawings in which:

-la figure 5 est une vue schématique des angles d'articulation prévus selon l'invention.FIG 5 is a schematic view of the articulation angles provided according to the invention.
De manière connue en soi, notamment par les documents cités en tête de cette description, l'articulation entre le dossier et l'assise d'un siège est obtenue par un mécanisme d'articulation constitué par deux flasques ronds pouvant tourner entre eux, l'un des flasques étant solidarisé à une ferrure liée à l'assise du siège, dite brancard de siège 1, et l'autre flasque étant solidarisé à une ferrure 6 liée au dossier. La rotation relative des deux flasques est empêchée en temps normal par un système de verrouillage constitué par des grains radiaux dentelés portés par l'un des flasques et venant appuyer radialement contre une couronne dentée formée dans un épaulement circulaire porté par l'autre flasque et munie de secteurs crantés et de secteurs non crantés. Les grains radiaux peuvent être simultanément débrayés de leur engrènement avec l' épaulement circulaire en actionnant un mécanisme commandé par un axe d'articulation 2 portant une poignée de manœuvre (ou relié à des moyens d'actionnement). La manœuvre de l'axe d'articulation 2 permet donc de faire pivoter l'un par rapport à l'autre les deux flasques et donc d'incliner plus ou moins le dossier de siège par rapport à l'assise, et le relâchement de l'axe d'articulation fait engrener à nouveau les grains dans l' épaulement circulaire et fixe une nouvelle position du dossier, sauf si les grains se trouvent alors en face d'une partie non crantée, auquel cas l'inclinaison du dossier se poursuit jusqu'à ce que les grains se trouvent à nouveau devant une partie crantée, la position d'arrivée et de blocage étant du reste approximative.In a manner known per se, in particular by the documents cited at the beginning of this description, the articulation between the backrest and the seat of a seat is obtained by a hinge mechanism consisting of two round flanges that can rotate between them, one of the flanges being secured to a fitting connected to the seat of the seat, said seat stretcher 1, and the other flange being secured to a fitting 6 linked to the backrest. The relative rotation of the two flanges is prevented in normal time by a locking system consisting of radial serrated grains carried by one of the flanges and coming to press radially against a ring gear formed in a circular shoulder carried by the other flange and provided with notched sectors and non-toothed sectors. The radial grains can be simultaneously disengaged from their meshing with the circular shoulder by actuating a mechanism controlled by a hinge pin 2 carrying a maneuvering handle (or connected to actuating means). Maneuvering the hinge pin 2 thus makes it possible to rotate the two flanges relative to one another and thus to incline more or less the seat back relative to the seat, and the relaxation of the hinge axis causes the grains to mesh again in the circular shoulder and fixes a new position of the backrest, unless the grains are then in front of a non-toothed part, in which case the inclination of the file continues until the grains are again in front of a notched part, the arrival and blocking position being approximate.
Le dispositif de l'invention vise à exercer automatiquement, lors de l'inclinaison du dossier dans certaines positions, une action positive sur l'axe d'articulation pour empêcher le verrouillage en position. Le dispositif de l'invention vient s'adapter sur le brancard 1, lequel est en forme de L avec une branche horizontale destinée à la fixation sur l'assise de siège (non représentée) et une branche verticale dont la partie supérieure 3 arrondie et munie d'une bordure loge le mécanisme de l'articulation de type connu ayant sensiblement une forme de disque. Des trous permettent la fixation solide dudit mécanisme. L'axe ou tige d'articulation 2 dépasse du brancard 3 pour former une partie terminale 4 de section non circulaire (par exemple carrée) de manière à pouvoir recevoir en emboîtement un élément destiné à manœuvrer l'axe d'articulation 2. Un pièce de guidage 10 vient se fixer contre la surface extérieure de la branche verticale du brancard 1 en étant maintenue d'une part par des moyens de maintien 36 qui seront décrits ultérieurement et maintiennent la pièce 10 autour de l'embout sortant de l'axe 2 qui pénètre dans une ouverture 11 de la pièce de guidage, et d'autre part par un rivet d'assemblage 12 passant dans les trous 5 et 13 du brancard 1 et de la pièce de guidage 10. Autour de l'ouverture 11, une nervure circulaire 14 est formée pour recevoir en rotation un organe de came 30 décrit plus loin. Enfin, la pièce de guidage 10 comporte en son milieu une lumière de guidage 15 en forme de pistolet dont la pointe est dirigée vers la l'ouverture 11. La lumière 15, entourée d'une plage 15', est formée dans une paroi 16 de la pièce de guidage 10 qui se trouve décalée en avant par rapport à la paroi dans laquelle est pratiqué le trou 13 de fixation, de manière que, quand la pièce de guidage 10 est fixée contre le brancard 1, il y ait derrière la paroi 16 suffisamment de place pour le logement et le déplacement d'autres organes plats du mécanisme de l'invention, à savoir une biellette arrière 20 et une biellette avant 21. La biellette avant 21 est un simple bras court comportant vers une extrémité une lumière 22 destinée à engager avec jeu l'embout 4 de l'axe d'articulation 2 de façon à en être solidaire en rotation, et vers l'autre extrémité un trou 23. La biellette arrière 20 est en arc de cercle et comporte à ses extrémités des trous 24 et 25. Un rivet de maintien 26 vient traverser la lumière 15 de la pièce de guidage 10 et se fixer derrière le trou 24 de la biellette 20 ; le rivet 26 est maintenu en saillie à l'avant de la lumière 15 grâce à une bague de frottement 27 qui vient frotter sur la plage 15' entourant la lumière 15. Un rivet 28 et une rondelle 29 viennent assembler en articulation la biellette 20 et la biellette 21 par leur trou respectif 25 et 23. Une pièce de came 30 est rendue solidaire de la ferrure 6 du dossier de siège grâce à des rivets d'assemblage 31 et des trous 32 dans la came 30. La pièce 30 a une forme plate pliée en Z de manière à former une partie 33 en contact avec la ferrure 6 du dossier située à un niveau différent de la partie opposée parallèle 35, ces deux parties 33 et 35 parallèles à la ferrure 6 étant séparées par une partie perpendiculaire 34. La partie 35 vient coiffer l'organe de guidage 10 et le maintenir en position grâce à la coopération de la nervure circulaire 14 et d'un orifice 36 dans lequel elle s'introduit avec jeu. La partie 35 comporte une patte de came 37 définissant un profil de came destiné à coopérer avec le rivet de maintien 26 disposé dans la lumière 15 de l'organe de guidage. La forme et la fonction de cette page de came ressortiront des explications qui vont être données en liaison avec les figures 2 à 5. La figure 2 montre le siège en position de confort, comme le montre l'inclinaison légère vers l'arrière (25°) de la ferrure 6 de dossier par rapport au brancard de siège 1. Dans cette position, la patte de came 37 est dirigée vers le bas et n'interfère pas avec le rivet de maintien 26 qui se trouve à l'extrémité droite de la lumière 15 de la pièce de guidage 10. Dans la figure 3, le siège est en position extrême de verrouillage vers l'avant, avec la ferrure 6 inclinée vers l'avant (par exemple 10°). Le rivet de maintien 26 est logé dans un creux 38 du profil gauche de la patte de came 37, juste avant d'aborder une rampe 39 qui s'éloigne de l'axe 4 de la pièce 30. Pour aborder cette rampe, il faut manœuvrer d'abord le mécanisme d'articulation par la tige 4 ce qui a pour effet, par le jeu des biellettes 20, 21, d'envoyer le rivet de maintien 26 au fond opposé de la lumière 15, à gauche, comme représenté dans la figure 4 et de rendre possible la rotation du siège.The device of the invention aims to automatically exert, during the inclination of the backrest in certain positions, a positive action on the axis of articulation to prevent locking in position. The device of the invention fits on the stretcher 1, which is L-shaped with a horizontal branch for attachment to the seat cushion (not shown) and a vertical branch whose upper part 3 rounded and provided with a border houses the mechanism of the known type of articulation having substantially a disc shape. Holes allow the solid attachment of said mechanism. The axis or hinge pin 2 protrudes from the stretcher 3 to form an end portion 4 of non-circular section (for example square) so as to be able to receive in interlocking an element intended to maneuver the hinge pin 2. One piece guide 10 is fixed against the outer surface of the vertical branch of the stretcher 1 being maintained on the one hand by holding means 36 which will be described later and maintain the piece 10 around the tip out of the axis 2 which enters an opening 11 of the guide piece, and secondly by an assembly rivet 12 passing through the holes 5 and 13 of the stretcher 1 and the guide piece 10. Around the opening 11, a circular rib 14 is formed to receive in rotation a cam member 30 described later. Finally, the guide piece 10 comprises at its center a guide light 15 in the form of a gun whose tip is directed towards the opening 11. The light 15, surrounded by a beach 15 ', is formed in a wall 16 the guide piece 10 which is offset forwards with respect to the wall in which the fixing hole 13 is made, so that when the guide piece 10 is fixed against the stretcher 1, there is behind the wall 16 sufficient room for housing and moving other flat members of the mechanism of the invention, namely a rear link 20 and a front link 21. The front link 21 is a simple short arm having a light towards one end 22 intended to engage with play the tip 4 of the hinge pin 2 so as to be integral in rotation, and towards the other end a hole 23. The rear link 20 is in an arc and has at its ends holes 24 and 25. One bank holding t 26 passes through the lumen 15 of the guide piece 10 and is fixed behind the hole 24 of the rod 20; the rivet 26 is held projecting at the front of the slot 15 by means of a friction ring 27 which rubs on the beach 15 'surrounding the slot 15. A rivet 28 and a washer 29 come together in articulation with the link 20 and the rod 21 by their respective hole 25 and 23. A cam member 30 is secured to the fitting 6 of the seat back by means of assembly rivets 31 and holes 32 in the cam 30. The piece 30 has a shape flattened Z-shaped so as to form a part 33 in contact with the fitting 6 of the backrest situated at a different level from the parallel opposite part 35, these two parts 33 and 35 parallel to the fitting 6 being separated by a perpendicular part 34. The part 35 caps the guide member 10 and maintain it in position through the cooperation of the circular rib 14 and an orifice 36 into which it is introduced with clearance. The portion 35 comprises a cam lug 37 defining a cam profile intended to cooperate with the retaining rivet 26 disposed in the slot 15 of the guide member. The shape and function of this page will appear from the explanations that will be given in connection with Figures 2 to 5. Figure 2 shows the seat in the comfort position, as shown by the slight backward tilt (25). °) of the backrest fitting 6 with respect to the seat stretcher 1. In this position, the cam lug 37 is directed downwards and does not interfere with the retaining rivet 26 which is at the right end of the seat strut. the light 15 of the guide piece 10. In FIG. 3, the seat is in the extreme forward locking position, with the fitting 6 inclined forwards (for example 10 °). The retaining rivet 26 is housed in a recess 38 of the left profile of the cam lug 37, just before approaching a ramp 39 which moves away from the axis 4 of the part 30. To approach this ramp, it is necessary to firstly operate the hinge mechanism by the rod 4 which has the effect, by the play of rods 20, 21, to send the retaining rivet 26 to the opposite end of the light 15, on the left, as shown in FIG. Figure 4 and make possible the rotation of the seat.
Le mécanisme étant déverrouillé, le siège peut être rabattu plus avant comme le montre la figure 4 ; ce faisant, une partie circulaire 40 de la patte de came 37 succède à la rampe 39 et maintient le rivet 26 en position à gauche dans la lumière 15, c'est-à-dire en position de déverrouillage de l'articulation, même si celle-ci les grains de celle-ci sont devant un secteur cranté de l'articulation. Les grains n'engrènent pas puisque le mécanisme est déverrouillé, et le siège ne se bloque pas dans cette position mais peut poursuivre sa course jusqu'à la position représentée en figure 5 où le siège est horizontal.The mechanism being unlocked, the seat can be folded further forward as shown in Figure 4; in doing so, a circular portion 40 of the cam tab 37 succeeds to the ramp 39 and maintains the rivet 26 in the left position in the slot 15, that is to say in the unlocked position of the joint, even if this one the grains of this one are in front of a notched sector of the articulation. The grains do not mesh since the mechanism is unlocked, and the seat does not lock in this position but can continue its race to the position shown in Figure 5 where the seat is horizontal.
Dans cette position, la patte de came 37 offre soudainement un profil creux 41 au rivet 26, qui, au sortir du plateau 40 tombe donc dans ce profil creux et vient, sous l'effet de l'élasticité du mécanisme d'articulation, regagner l'extrémité droite de la lumière 15 et donc reverrouiller le mécanisme d'articulation. Les grains peuvent alors engrener avec le secteur denté qu'ils ont en face d'eux, et le siège se trouve verrouillé dans cette position en tablette, exactement à l'horizontale. Pour remettre le siège en position droite, il suffit de manœuvrer la tige 4 pour déverrouiller le mécanisme et, la manœuvre de la tige 4 ayant par l'intermédiaire des biellettes 20, 21 repoussé le rivet de maintien vers la gauche, de redresser librement le siège. La figure 6 résume les possibilités d'inclinaison de siège et de verrouillage en position conformément à l'invention. On y voit en A la position couchette du siège, à 65° d'inclinaison vers l'arrière par rapport à l'axe vertical Y (inclinaison maximale limitée par une butée mécanique), en B la position dite de confort à 25° vers l'arrière, et en X la position escamotée ou rabattue en tablette vers l'avant, confondue avec l'axe horizontal.In this position, the cam lug 37 suddenly offers a hollow profile 41 to the rivet 26, which, at the end of the plate 40 therefore falls into this hollow profile and comes, under the effect of the elasticity of the articulation mechanism, regain the right end of the light 15 and thus relock the hinge mechanism. The grains can then mesh with the toothed sector they have in front of them, and the seat is locked in this tablet position, exactly horizontal. To return the seat to the upright position, it is sufficient to maneuver the rod 4 to unlock the mechanism and, the maneuvering of the rod 4 having, by means of the rods 20, 21 pushed back the retaining rivet to the left, to freely straighten the seat. Figure 6 summarizes the possibilities of seat inclination and locking in position according to the invention. It shows in A the bunk position of the seat, at 65 ° inclination towards the rear relative to the vertical axis Y (maximum inclination limited by a mechanical stop), in B the so-called comfort position at 25 ° towards the back, and in X the retracted position or folded forward tablet, confused with the horizontal axis.
Par ailleurs, le mécanisme d'articulation utilisé, connu en soi, comporte trois secteurs de 120° coopérant avec trois grains, chaque secteur de 120° se divisant en un secteur cranté C, C, C" de 75° et un secteur non cranté NC, NC, NC" faisant les 45° restants. L'utilisateur règle la position du siège dans la zone angulaire « beta ». S'il souhaite escamoter le dossier du siège en position X, il doit manœuvrer le mécanisme d'articulation ce qui désengrène les grains d'avec les secteurs crantés C, C et C". Mais, une fois passé les 10° en avant de la zone angulaire « gamma », il peut relâcher la poignée de manœuvre, puisque dans les 45° suivants, les grains seront devant les secteurs non crantés NC, NC, NC", et qu'à partir de la zone terminale « alpha » de 35°, le dispositif de l'invention forcera, grâce à la came 37, la tige de manœuvre en position déverrouillée, empêchant l'engrènement des grains jusqu'à ce que la position X soit effectivement atteinte et que le profil de came 41 fasse revenir la tige de manœuvre 4 en position de verrouillage et donc d'engrènement des grains avec la zone crantée.Furthermore, the hinge mechanism used, known per se, comprises three sectors of 120 ° cooperating with three grains, each sector of 120 ° dividing into a notched sector C, C, C "of 75 ° and a notch sector NC, NC, NC "making the remaining 45 °. The user sets the position of the seat in the angular zone "beta". If he wishes to retract the seat back in position X, he must maneuver the articulation mechanism which disengages the grains from the notched sectors C, C and C. "But, once past the 10 ° ahead of the angular zone "gamma", it can release the handle, since in the next 45 °, the grains will be in front of the non-toothed sectors NC, NC, NC ", and that from the terminal zone" alpha "of 35 °, the device of the invention will force, thanks to the cam 37, the operating rod in the unlocked position, preventing the meshing of the grains until the position X is actually reached and the cam profile 41 makes return the operating rod 4 in the locking position and thus meshing grains with the notched zone.
Il va de soi qu'on peut choisir d'autres configurations angulaires pour définir les secteurs crantés et non crantés. Ainsi on peut , si on le souhaite, éviter d'avoir la zone angulaire « gamma » de 10° vers l'avant où le dossier est verrouillable, soit par un autre mécanisme de came ou un profil de came adapté qui éclipse le verrouillage dans cette zone soit plus simplement en tournant la couronne dentée de l'articulation de 10° vers l'arrière pour décaler d'autant les zones de crantage. It goes without saying that other angular configurations can be chosen to define the notched and notched sectors. Thus one can, if one wishes, to avoid having the angular zone "gamma" of 10 ° towards the front where the backrest is lockable, either by another mechanism of cam or a adapted profile of cam that eclipses the lock in this area is more simply by turning the ring gear of the articulation of 10 ° towards the back to shift all the notches zones.
