Description

« Dispositif d'escamotage à au moins deux positions de verrouillage pour un dossier de siège ou une partie de celui-ci ainsi que siège et véhicule automobile comprenant au moins un tel siège» "Retraction device with at least two locking positions for a seat back or part thereof and a seat and a motor vehicle comprising at least one such seat"
La présente invention concerne, d'une façon générale, un dispositif d'escamotage à au moins deux positions de verrouillage pour un dossier de siège ou une partie de celui-ci ainsi qu'un siège et un véhicule automobile comprenant au moins un tel siège.The present invention relates, in general, to a retraction device with at least two locking positions for a seat back or a part thereof and a seat and a motor vehicle comprising at least one such seat .
Plus particulièrement, la présente invention concerne un dispositif d'escamotage d'un dossier de siège ou d'une partie de celui-ci offrant, en partant d'une position d'utilisation normale en tant que siège passager dans laquelle ce dispositif permet un premier verrouillage, au moins une possibilité d'une position d'escamotage partiel ou complet d'au moins une partie de ce dossier, dans laquelle ce dispositif réalise un second verrouillage en position.More particularly, the present invention relates to a device for retracting a seat back or part of it offering, starting from a position of normal use as a passenger seat in which this device allows a first locking, at least one possibility of a partial or complete retraction position of at least a part of this folder, wherein this device performs a second locking in position.
Le siège du véhicule automobile peut être un siège passager avant ou arrière et quand la position d'escamotage est complète, celle-ci est particulièrement bien adaptée pour la réception d'un siège bébé ou d'un rehausseur pour enfant.The seat of the motor vehicle can be a front or rear passenger seat and when the retracted position is complete, it is particularly well suited for receiving a baby seat or booster for children.
L'invention va être présentée ci-après en prenant deux exemples qui ne sont pas limitatifs.The invention will be presented below by taking two examples that are not limiting.
Pour le premier exemple, dans l'habitacle d'un véhicule automobile, lorsque le siège passager avant est inoccupé, le volume de ce siège s'impose inutilement dans l'habitacle intérieur. Ainsi, lors d'un trajet, si un passager occupe la banquette arrière, le dossier et l'appui tête du siège avant inoccupé gênent considérablement son champ de vision. De plus, si ce passager souhaite disposer de plus d'espace vers l'avant, par exemple pour allonger ses jambes, il n'est pas possible actuellement de libérer cet espace devant ce passager sans à avoir à escamoter complètement le siège avant situé devant lui, ce qui est une opération demandant un certain temps de manipulation, voire même un arrêt du véhicule le temps de l'escamotage. Ceci vaut aussi pour le transport de charges longues dans l'habitacle du véhicule. Il y a donc un besoin existant d'élaborer un siège qui soit facilement, au moins en partie, escamotable et dont le verrouillage en position soit garanti. Le second exemple est relatif à l'apport optionnel d'un siège enfant. Aujourd'hui, la réglementation interdit aux jeunes enfants de s'asseoir à même la banquette ou sur les sièges arrière. Il est, de plus, exigé que les bébés de 0 à 9 Kg doivent être placés, de dos à la route, dans des sièges adaptés.For the first example, in the passenger compartment of a motor vehicle, when the front passenger seat is unoccupied, the volume of this seat is required unnecessarily in the interior passenger compartment. Thus, during a trip, if a passenger occupies the rear seat, the backrest and the headrest of the unoccupied front seat greatly hinder his field of vision. In addition, if this passenger wants more space forward, for example to extend his legs, it is not currently possible to release this space in front of the passenger without having to completely retract the front seat in front of him, which is an operation requiring a certain amount of time of handling, or even a stop of the vehicle the time of the retraction. This also applies to the transport of long loads in the passenger compartment of the vehicle. There is therefore an existing need to develop a seat that is easily, at least in part, retractable and locked position is guaranteed. The second example relates to the optional contribution of a child seat. Today, the regulations prohibit young children from sitting on the bench or in the rear seats. It is also required that babies from 0 to 9 kg should be placed back to the road in suitable seats.
Il est ainsi connu de positionner le bébé face au dossier du siège passager ou de la banquette arrière. Une telle disposition gêne cependant la convivialité dans l'habitacle et rend l'installation du bébé dans son siège malaisée.It is thus known to position the baby facing the back of the passenger seat or the rear seat. Such a provision, however, hinders the user-friendliness in the cabin and makes the installation of the baby in his seat difficult.
Les petits enfants sont, en général, installés dans des sièges additionnels à ceintures embarqués et fixés sur le véhicule par un système de fixation normalisé appelé isofix. Pour des enfants plus grands, il est connu d'utiliser un rehausseur d'assise disposé sur une place arrière et fixé par la sangle d'une ceinture de sécurité présente dans le véhicule.Small children are generally installed in additional seats with embedded belts and fixed to the vehicle by a standard fastening system called isofix. For older children, it is known to use a seat booster placed in a rear seat and fixed by the strap of a seat belt present in the vehicle.
Il est fréquent que la solidarisation du siège enfant avec le siège du véhicule ne se fasse que par son sanglage sur la banquette arrière ou le siège avant, ceci à l'aide de la ceinture de sécurité.It is common for the attachment of the child seat with the seat of the vehicle is done only by its strapping on the back seat or the front seat, this using the seat belt.
L'absence d'un autre mode de solidarisation entre le siège enfant et le siège du véhicule pose des problèmes de sécurité en cas de freinage puissant ou de virage serré puisque le siège enfant pourra avoir tendance à glisser dans ces conditions. De plus, le siège enfant est souvent laissé à demeure dans la voiture pour éviter son installation répétitive, et il peut donc gêner lors du transport de passagers ou d'objets encombrants, étant donné qu'il vient en superposition du siège passager qui le supporte.The absence of another mode of connection between the child seat and the vehicle seat poses safety problems in case of strong braking or tight turn as the child seat may tend to slip under these conditions. In addition, the child seat is often left in the car to avoid repetitive installation, and it can interfere with the transport of passengers or bulky objects, since it is superimposed on the passenger seat that supports it .
Il est donc souhaitable que le siège bébé ou enfant puisse être, au moins en partie, encastré dans un siège de véhicule automobile, notamment par escamotage du dossier de ce siège ou d'une partie de ce dossier afin de résoudre les problèmes ci-dessus évoqués.It is therefore desirable that the baby or child seat can be, at least in part, embedded in a motor vehicle seat, including by retraction of the back of this seat or part of this folder to solve the above problems mentioned.
Pour des raisons de sécurité évidentes, il convient aussi de verrouiller cette position d'escamotage du dossier de siège afin d'éviter tout mouvement intempestif du dossier ou d'une partie de ce dossier lors de la marche du véhicule automobile.For obvious safety reasons, it is also necessary to lock this position of retraction of the seat back to prevent inadvertent movement of the backrest or part of this folder during the running of the motor vehicle.
Ceci s'applique aussi pour d'autres formes d'escamotage d'un dossier ou d'une partie d'un dossier d'un véhicule automobile.This also applies to other forms of retraction of a folder or part of a folder of a motor vehicle.
Comme exemple d'autres formes d'escamotage possibles, on pourra citer le siège selon le document FR-As an example of other forms of possible retraction, one can quote the seat according to the document FR-
A-2 886 593 qui est un siège médian arrière et dont les parties haute et latérales du dossier sont rabattues pour former un accoudoir pour les passagers droit et gauche.A-2,886,593 which is a rear medial seat and whose upper and lateral parts of the backrest are folded down to form an armrest for the right and left passengers.
Ce document mentionne un mécanisme débrayable de blocage en position sans le décrire explicitement.This document mentions a disengageable locking mechanism in position without explicitly describing it.
Comme autre forme d'escamotage, le document JP-A- 7/232580 décrit un siège pour un véhicule automobile avec un cadre de dossier entourant une partie centrale dite médaillon. Ce médaillon est pliable en deux parties pour former un siège bébé. Le pliage se fait soit vers l'arrière du siège quand le cadre n'est pas rabattu vers l'assise, soit vers l'avant quand le cadre est rabattu.As another form of retraction, document JP-A-7/232580 describes a seat for a motor vehicle with a backrest frame surrounding a central part called medallion. This medallion is foldable in two parts to form a baby seat. The folding is done towards the back of the seat when the frame is not folded towards the seat, or towards the front when the frame is folded down.
Le dispositif d'escamotage avec blocage en position décrit dans ce document est cependant compliqué et met en jeu de nombreux éléments.The retraction device with locking in position described in this document is however complicated and involves many elements.
Le cas le plus fréquent d'escamotage d'un dossier de siège est cependant le rabattement du dossier contre la face supérieure de l'assise associée afin de former une tablette.The most common case of retraction of a seat back is however the folding of the file against the upper face of the associated seat to form a tablet.
Par exemple, le document FR-A-2 799 420 décrit un siège pour un véhicule automobile avec une structure de dossier rabattable contre l'assise de ce siège. Pour le maintien en position du dossier du siège, ce dernier comprend un premier mécanisme de blocage en position d'utilisation normale, ce mécanisme étant commandé par un premier organe d'actionnement . Ce siège comprend aussi un second mécanisme de blocage commandé par un second organe d'actionnement .For example, document FR-A-2 799 420 describes a seat for a motor vehicle with a folding backrest structure against the seat of this seat. In order to hold the seat back in position, the latter comprises a first locking mechanism in the normal use position, this mechanism being controlled by a first actuating member. This seat also comprises a second locking mechanism controlled by a second actuating member.
Le dispositif d'escamotage divulgué par ce document est compliqué, mettant en jeu de nombreux éléments, prend une grande place en s 'étendant sur une longue partie du côté latéral de la structure de dossier. Il conviendrait de simplifier ce dispositif en combinant, par exemple, les premier et second organes d'actionnement en un unique élément .The retraction device disclosed by this document is complicated, involving many elements, takes a large place by extending over a long portion of the lateral side of the backrest structure. This device should be simplified by combining, for example, the first and second actuators into a single element.

L'effet technique obtenu est essentiellement, d'une part, d'utiliser le même élément de l'assise pour assurer le verrouillage du dispositif d'escamotage dans les deux positions du dossier et, d'autre part, d'entraîner automatiquement le verrouillage du dispositif dans la position escamotée à la fin du déplacement désiré de ce dossier .The technical effect obtained is essentially, on the one hand, to use the same element of the seat to ensure the locking of the retraction device in the two positions of the folder and, secondly, to train automatically locking the device in the retracted position at the end of the desired movement of this folder.
Cela entraîne une simplification du dispositif d'escamotage et des éléments de verrouillage correspondants prévus sur le siège.This results in a simplification of the retraction device and the corresponding locking elements provided on the seat.
Le dispositif d'escamotage, selon la présente invention, est ainsi de forme compacte et tient une place réduite entre la partie latérale inférieure du dossier et la partie de l'assise en vis-à-vis. Le nombre d'éléments mis en jeu lors des verrouillages et déverrouillages est considérablement réduit par rapport aux dispositifs de l'état de la technique.The retraction device according to the present invention is thus compact in shape and has a reduced space between the lower lateral part of the backrest and the part of the seat facing each other. The number of elements involved during locks and unlockings is considerably reduced compared to devices of the state of the art.
L'invention va maintenant être décrite plus en détail mais de façon non limitative en regard des figures annexées, dans lesquelles :The invention will now be described in more detail but in a nonlimiting manner with reference to the appended figures, in which:
- la figure 1 est une vue latérale montrant la partie inférieure du dossier d'un siège avec le dispositif d'escamotage selon la présente l'invention, le dossier de ce siège étant en position normale d'utilisation, c'est à dire non escamotée, la figure 2 est une vue latérale montrant la partie inférieure de la structure d'un siège avec le dispositif d'escamotage selon la présente l'invention, le dossier de ce siège étant en position escamotée, la figure 3 est une vue de derrière en perspective montrant la partie inférieure du dossier du siège avec le dispositif d'escamotage selon la présente l'invention, le dossier de ce siège étant en position escamotée .- Figure 1 is a side view showing the lower part of the back of a seat with the retraction device according to the present invention, the back of this seat being in the normal position of use, ie no 2 is a side view showing the lower part of the structure of a seat with the retraction device according to the present invention, the back of this seat being in the retracted position, FIG. 3 is a view of rear perspective view showing the lower part of the seat back with the retraction device according to the present invention, the back of this seat being in the retracted position.
Dans ce qui va suivre, la ou les positions d'escamotage du siège ne sont pas précisées. II est à garder à l'esprit que le dispositif d'escamotage à deux positions de verrouillage selon la présente invention peut convenir pour toutes formes d'escamotage d'une structure de dossier par rapport à une structure d'assise d'un siège.In what follows, the seat retraction position or positions are not specified. It should be borne in mind that the retraction device with two locking positions according to the present invention may be suitable for all forms retracting a backrest structure relative to a seating structure of a seat.
De même, tout le dossier ou seulement une partie de celui-ci peut être escamoté dans le cadre de la présente invention.Likewise, the whole file or only a part of it can be retracted within the framework of the present invention.
Il est aussi possible qu'une partie du dossier soit escamotée et qu'ensuite le reste du dossier soit aussi escamoté. Dans ce cas, la structure de dossier est composée d'une partie escamotable présentant des moyens de pivotement par rapport à la structure de dossier, cette dernière présentant en outre des moyens de pivotement par rapport à la structure d'assise.It is also possible that part of the file is retracted and then the rest of the file is also retracted. In this case, the backrest structure is composed of a retractable part having pivoting means relative to the backrest structure, the latter further having pivoting means relative to the seat structure.
C'est le cas par exemple quand une partie médiane du dossier ou inversement son pourtour est escamotable par rapport au dossier et que lui-même est ensuite escamotable, le plus fréquemment par rabattement vers l'assise du siège.This is the case for example when a median part of the backrest or conversely its periphery is retractable from the backrest and that it is then retractable, most often by folding towards the seat.
Il est aussi à préciser que le siège comportant le dispositif selon la présente invention peut être un siège quelconque présentant au moins deux positions de réglage qui peuvent être verrouillées et que son utilisation dans un véhicule automobile est seulement une application préférentielle, le siège pouvant être un siège passager de n'importe quel moyen de locomotion. Dans le cas d'un quelconque moyen de locomotion, le siège comportant le dispositif selon la présente invention peut être un siège arrière ou avant, ce siège présentant au moins deux positions de réglage de son dossier ou d'une partie de celui-ci, ces positions pouvant être verrouillées.It should also be noted that the seat comprising the device according to the present invention may be any seat having at least two adjustment positions that can be locked and that its use in a motor vehicle is only a preferential application, the seat being able to be a passenger seat of any means of locomotion. In the case of any means of locomotion, the seat comprising the device according to the present invention may be a rear seat or front, this seat having at least two positions of adjustment of its backrest or part thereof, these positions can be locked.
D'une manière classique, un siège est composé d'un dossier, ainsi que d'une assise. Il sera fait référence aux structures de dossier et d'assise afin de préciser que le dispositif d'escamotage est intégré dans les composants de base de ce dossier et de cette l'assise.In a classic way, a seat is composed of a backrest, as well as a seat. Reference will be made to the backrest and seat structures in order to specify that the retraction device is integrated into the basic components of this file and this seat.
En se référant aux figures 1 à 3 qui ne montrent que partiellement ces structures de dossier 2a et d'assise 3a, la structure de dossier 2a est articulée à sa partie inférieure adjacente par rapport à la structure d'assise 3a autour d'un axe inférieur Al, cet axe inférieur Al s 'étendant transversalement à la structure d'assise 3a. Ceci est fait par l'intermédiaire du dispositif d'escamotage 1 à deux positions de verrouillage selon la présente invention.Referring to Figures 1 to 3 which only partially show these file structures 2a and 3a seat, the backrest structure 2a is hinged to its lower portion adjacent to the seat structure 3a about a lower axis A1, this lower axis A1 extending transversely to the seat structure 3a. This is done through the retraction device 1 with two locking positions according to the present invention.
La figure 2 montre une position d'escamotage de la structure de dossier 2a. Cet escamotage peut être initié par un mouvement de déverrouillage du dispositif 1 selon la présente invention et un basculement de la structure de dossier 2a vers l'avant, en le rabattant plus ou moins sensiblement contre la structure d'assise 3a.Figure 2 shows a retracted position of the backrest structure 2a. This retraction can be initiated by an unlocking movement of the device 1 according to the present invention and a tilting of the backrest structure 2a towards the front, by folding it more or less substantially against the seat structure 3a.
Ceci est obtenu grâce au déverrouillage du dispositif d'escamotage 1 à deux positions de verrouillage selon la présente invention comme il va être montré ultérieurement.This is achieved by unlocking the retraction device 1 with two locking positions according to the present invention as will be shown later.
Le pivotement de la structure de dossier 2a ou au moins d'une partie de celle-ci peut être avantageusement initié par un moyen quelconque complétant ou remplaçant une poussée de l'utilisateur sur cette structure 2a vers l'assise. Ce moyen quelconque peut être, par exemple, un ressort 22 de torsion, exerçant une force de rappel en position d'escamotage, ce ressort 22 pouvant être enroulé autour de l'axe Al de pivotement du dossier par rapport à 1 'assise .The pivoting of the backrest structure 2a or at least a portion thereof can be advantageously initiated by any means supplementing or replacing a push of the user on the structure 2a towards the seat. This means may be, for example, a torsion spring 22, exerting a restoring force in the retracted position, this spring 22 being able to be wound around the axis A1 of pivoting of the backrest with respect to the seat.
De même, ce pivotement de la structure de dossier 2a ou au moins d'une partie de celle-ci peut être avantageusement réglé en étant limité par une butée de rotation pour obtenir sa position voulue d'inclinaison ou d'au moins une partie de celle-ci par rapport à la structure d'assise 3a.Similarly, this pivoting of the backrest structure 2a or at least a portion thereof can be advantageously adjusted by being limited by a rotation stop to obtain its desired position of inclination or at least a portion of it with respect to the seat structure 3a.
Lors d'un escamotage complet, qui peut être une des formes possibles d'escamotage prévu dans la présente invention, la structure de dossier 2a est alors rabattue plus ou moins complètement contre la structure d'assise 3a. Cette structure de dossier 2a peut être alors rabattue jusqu'à former un angle faible avec la face supérieure de cette structure d'assise 3a, cette face étant sensiblement en position horizontale.When a complete retraction, which may be one of the possible forms of retraction provided in the present invention, the backrest structure 2a is then folded more or less completely against the seat structure 3a. This folder structure 2a can then be folded to form a small angle with the upper face of the seat structure 3a, this face being substantially in a horizontal position.
Les figures 1, 2 et 3 montrent essentiellement le dispositif d'escamotage 1 à au moins deux positions de verrouillage de la structure de dossier 2a dans deux positions et cela selon divers angles de vue.Figures 1, 2 and 3 show essentially the retraction device 1 at at least two locking positions of the backrest structure 2a in two positions and that according to various angles of view.
La figure 1 montre le siège avec son dossier verrouillé en position normale d'utilisation, tandis que les figures 2 et 3 montrent le siège avec son dossier verrouillé en position escamotée, à ces figures un rabattement de ce dossier vers l'assise.Figure 1 shows the seat with its back locked in the normal position of use, while Figures 2 and 3 show the seat with its backrest locked in the retracted position, in these figures a folding of this folder to the seat.
Ce dispositif 1 peut aussi servir pour un escamotage d'une partie du dossier, par exemple de son contour ou au contraire de sa partie centrale ou médaillon, cette partie étant intégrée dans la structure de dossier qui l'entoure au moins latéralement.This device 1 can also be used for a retraction of a part of the file, for example its outline or the opposite of its central part or medallion, this part being integrated into the backrest structure which surrounds it at least laterally.
Ce dispositif 1 est actif, d'une part, entre une structure d'assise 3a, reliée au plancher du véhicule, par l'intermédiaire de supports 15 munis avantageusement de glissières afin d'assurer un réglage longitudinal du siège et, d'autre part, une structure de dossier 2a.This device 1 is active, on the one hand, between a seat structure 3a, connected to the floor of the vehicle, via supports 15 advantageously provided with slides to provide longitudinal adjustment of the seat and, on the other hand, part, a file structure 2a.
Un tel dispositif 1 peut être placé sur un côté latéral du siège entre la partie inférieure de la structure de dossier 2a et la structure d'assise 3a ou en alternative des deux côtés latéraux du siège entre ces deux structures 2a et 3a.Such a device 1 can be placed on a lateral side of the seat between the lower part of the backrest structure 2a and the seat structure 3a or alternatively the two lateral sides of the seat between these two structures 2a and 3a.
Ce dispositif d'escamotage 1 selon l'invention présente la caractéristique de pouvoir verrouiller la structure de dossier 2a par rapport à la structure d'assise 3a dans au moins deux positions.This retraction device 1 according to the invention has the characteristic of being able to lock the backrest structure 2a with respect to the seat structure 3a in at least two positions.
La première est une position d'utilisation normale ou le dossier est relevé tandis que la seconde est une position où la structure de dossier 2a est escamotée, aux figures 2 et 3 inclinée vers la structure d'assise 3a.The first is a normal use position or the backrest is raised while the second is a position where the backrest structure 2a is retracted, in Figures 2 and 3 inclined to the seat structure 3a.
Ce dispositif 1 selon l'invention est formé essentiellement d'une partie de liaison 11. Cette partie de liaison est aux figures illustrée par un flasque 11 latéral présentant sensiblement une forme d'équerre, muni de deux branches avec un angle droit à la réunion de ces deux branches. Ce flasque 11, illustrant la partie de liaison, est fixé par l'extrémité de sa première branche à l'extrémité inférieure latérale de la structure de dossier 2a du siège. Cette fixation peut s'effectuer par un plot de contact lia solidaire de la structure de dossier 2a et pénétrant dans la première branche du flasque 11 sans possibilité de déplacement du flasque 11 par rapport à ce plot lia.This device 1 according to the invention consists essentially of a connecting part 11. This part link is shown in Figures illustrated by a side flange 11 having substantially a square shape, provided with two branches with a right angle to the meeting of these two branches. This flange 11, illustrating the connecting part, is fixed by the end of its first branch to the lower lateral end of the backrest structure 2a of the seat. This attachment can be carried out by a contact pad 11a integral with the backrest structure 2a and penetrating into the first leg of the flange 11 without the possibility of movement of the flange 11 relative to the stud 11a.
La fixation entre le flasque 11, illustrant la partie de liaison, et la structure de dossier 2a peut aussi s'effectuer, par exemple par soudage, vissage, collage ou tout autre moyen de solidarisation .Fixing between the flange 11, illustrating the connecting portion, and the backrest structure 2a can also be effected, for example by welding, screwing, gluing or any other securing means.
Ce flasque 11 est aussi relié à la structure d'assise 3a de siège avec une possibilité de pivotement par rapport à celle-ci. Ce pivotement s'effectue latéralement à la structure d'assise 3a de siège par pivotement autour d'un axe Al à l'extrémité de la seconde branche du flasque 11, cet axe Al s 'étendant transversalement à la structure d'assise 3a.This flange 11 is also connected to the seat seat structure 3a with a possibility of pivoting relative thereto. This pivoting is effected laterally to the seat seat structure 3a by pivoting about an axis A1 at the end of the second branch of the flange 11, this axis A1 extending transversely to the seat structure 3a.
Ce flasque 11, représentant la partie de liaison, comprend un premier pion 6 disposé vers son extrémité formant l'angle droit ainsi qu'un second pion 8a disposé à la partie inférieure de sa seconde branche, plus ou moins au voisinage de son axe de pivotement Al par rapport à la structure d'assise 3a. La structure d'assise 3a comprend un moyen de verrouillage complémentaire à ceux portés par le dispositif 1 d'escamotage selon l'invention pour le verrouillage dans chacune des positions. Les moyens de verrouillage du dispositif dans sa seconde position seront décrits ultérieurement.This flange 11, representing the connecting portion, comprises a first pin 6 disposed towards its end forming the right angle and a second pin 8a disposed at the lower part of its second branch, more or less in the vicinity of its axis. Al pivoting with respect to the seat structure 3a. The seat structure 3a comprises a locking means complementary to those carried by the retraction device 1 according to the invention for locking in each of the positions. The locking means of the device in its second position will be described later.
Le moyen de verrouillage complémentaire est sous la forme d'un crochet 20 qui est relié à la structure d'assise 3a par un axe A4 avec possibilité de pivotement autour de cet axe. Dans la position normale d'utilisation, le crochet 20, par sa tête 20a de crochet, coopère avec le premier pion 6 solidaire du flasque 11, ce premier pion 6 formant le premier moyen de verrouillage du dispositif 1 selon l'invention.The complementary locking means is in the form of a hook 20 which is connected to the structure of seat 3a by an axis A4 with possibility of pivoting about this axis. In the normal use position, the hook 20, by its hook head 20a, cooperates with the first pin 6 secured to the flange 11, the first pin 6 forming the first locking means of the device 1 according to the invention.
L'axe A4 de pivotement du crochet 20 est disposé dans sa partie médiane et l'extrémité du crochet, opposée à sa tête 20a, est reliée à un câble 5 d'actionnement dont la traction opère le pivotement du crochet 20 autour de son axe A4 médian.The pivot axis A4 of the hook 20 is disposed in its median part and the end of the hook, opposite its head 20a, is connected to an actuating cable 5 whose traction operates to pivot the hook 20 about its axis. Median A4.
Ce crochet 20 est avantageusement doublé afin de pouvoir plus efficacement effectuer le verrouillage du pion 6 du flasque 11 et du pion 21a de l'élément 21 comme il sera vu dans ce qui va suivre.This hook 20 is advantageously doubled in order to more effectively perform the locking of the pin 6 of the flange 11 and the pin 21a of the element 21 as will be seen in what follows.
Ceci est particulièrement visible à la figure 3, qui montre deux crochets 20b et 20c similaires et faiblement espacés. L'axe A4 de pivotement de l'un 20b des crochets est aussi celui de l'autre crochet 20c. En regard de la figure 1, le crochet 20 est solidaire de la structure d'assise 3a par l'intermédiaire d'une plaque 23, sur laquelle il est articulé sensiblement dans sa partie longitudinale médiane autour de son axe de pivotement A4, comme mentionné précédemment .This is particularly visible in Figure 3, which shows two hooks 20b and 20c similar and slightly spaced. The pivot axis A4 of one 20b of the hooks is also that of the other hook 20c. With reference to FIG. 1, the hook 20 is secured to the seat structure 3a by means of a plate 23, on which it is articulated substantially in its central longitudinal part about its pivot axis A4, as mentioned previously.
Le moyen de verrouillage dans une seconde position du dispositif d'escamotage 1 selon la présente invention est porté par un élément 21 qui va être maintenant décrit . Comme il sera vu particulièrement aux figures 2 et 3, cet élément 21 est de forme allongée et est relié à une première extrémité avec le flasque 11, formant la partie de liaison, par des moyens présentant une possibilité limitée de déplacement de ce flasque 11 par rapport audit élément 21.The locking means in a second position of the retraction device 1 according to the present invention is carried by an element 21 which will now be described. As will be seen particularly in FIGS. 2 and 3, this element 21 is of elongate shape and is connected at a first end with the flange 11, forming the connecting part, by means presenting a limited possibility of displacement of this flange 11 by report to said element 21.
L'autre extrémité de cet élément 21 porte le second moyen de verrouillage qui est sous la forme d'un pion 21a. Ce pion 21a de verrouillage pénètre dans la tête de crochet 20a afin de verrouiller en position le dossier rabattu vers l'assise, ce qui constitue le second moyen de verrouillage, ceci pour la position escamotée du dossier.The other end of this element 21 carries the second locking means which is in the form of a pawn 21a. This lock pin 21a enters the hook head 20a to lock in position the folded back to the seat, which is the second locking means, this for the retracted position of the folder.
L'élément 21 peut être avantageusement sous la forme d'une bielle. La géométrie de cet élément 21 peut aussi être différente afin de s'adapter à d'autres cinématiques et distances de verrouillage entre les structures de dossier 2a et d'assise 3a.The element 21 may advantageously be in the form of a connecting rod. The geometry of this element 21 may also be different in order to adapt to other kinematics and locking distances between the backrest structures 2a and seat 3a.
L'élément 21, sous forme d'une bielle aux figures 2 et 3, est avantageusement relié à un point de la base du flasque 11 en forme d'équerre, ceci par l'intermédiaire du second pion 8a porté par ce flasque 11. Avantageusement, ce second pion 8a du flasque 11, aux figures sous forme d'une équerre pour illustrer la partie de liaison entre structures de dossier 2a et d'assise 3a, se trouve à l'extrémité de ce flasque 11 formant son angle droit. Ce pion 8a du flasque 11 pénètre dans une lumière 8b, présente sur l'élément 21 vers son extrémité opposée à celle portant le second moyen de verrouillage 21a. Cela permet une liberté de déplacement de ce pion 8a dans la lumière 8b de l'élément 21, le déplacement de ce pion 8a se produisant principalement lors de l'escamotage du dossier de siège.The element 21, in the form of a connecting rod in FIGS. 2 and 3, is advantageously connected to a point of the base of the flange 11 in the shape of a square, this by means of the second pin 8a carried by this flange 11. Advantageously, this second pin 8a of the flange 11, to the figures in the form of a bracket to illustrate the connection portion between backrest structures 2a and seat 3a, is at the end of the flange 11 forming its right angle. This pin 8a of the flange 11 enters a slot 8b, present on the element 21 towards its end opposite that carrying the second locking means 21a. This allows freedom of movement of the pin 8a in the light 8b of the element 21, the movement of the pin 8a occurs mainly during the retraction of the seat back.
L'élément 21 est aussi articulé dans sa partie médiane autour de l'axe A3 solidaire de la structure 3a d'assise comme montré aux figures 2 et 3. Cette solidarisation s'effectue par l'intermédiaire de la plaque 23 déjà mentionnée.The element 21 is also articulated in its median part about the axis A3 integral with the seat structure 3a as shown in Figures 2 and 3. This connection is effected via the plate 23 already mentioned.
Le fonctionnement du dispositif d'escamotage 1 avec au moins deux positions de verrouillage lors de l'escamotage partiel ou complet du dossier de siège va être expliqué ci-après.The operation of the retraction device 1 with at least two locking positions during the partial or complete retraction of the seat back will be explained below.
L'initiation du mouvement d'escamotage de la position normale d'utilisation en tant que siège passager à la position escamotée s'effectue par l'intermédiaire d'un moyen de commande de déverrouillage, par exemple comme une poignée de commande, avantageusement disposée à la partie supérieure d'un côté latéral de la structure de dossier 2a.The initiation of the retraction movement from the normal position of use as a passenger seat in the retracted position is effected by means of an unlocking control means, for example as a control handle, advantageously arranged at the upper part of a lateral side of the backrest structure 2a.
La traction d'un opérateur sur cette poignée commande la désolidarisation du crochet 20 avec le premier pion 6 du flasque 11 par l'intermédiaire d'un câble 5, ce qui correspond à la désolidarisation de la première position de verrouillage correspondant à une utilisation normale du dossier du siège.The traction of an operator on this handle controls the separation of the hook 20 with the first pin 6 of the flange 11 by means of a cable 5, which corresponds to the separation of the first locking position corresponding to normal use of the seat back.
Ce câble 5 est relié à l'extrémité du crochet 20 opposée à celle portant sa tête 20a. La traction du câble 5 sur cette extrémité fait pivoter le crochet 20 autour de son axe A4 médian, ce qui libère le pion de verrouillage 6 du flasque 11 de sa retenue opérée par la tête 20a correspondante du crochet 20.This cable 5 is connected to the end of the hook 20 opposite to that carrying its head 20a. The traction of the cable 5 on this end pivots the hook 20 about its median axis A4, which releases the locking pin 6 of the flange 11 of its retention operated by the corresponding head 20a of the hook 20.
Cela permet ainsi la mise en pivotement selon la flèche Fl de la structure de dossier 2a, afin qu'elle soit rabattue vers la partie supérieure formant siège de la structure d'assise 3a.This allows the pivoting according to the arrow Fl of the backrest structure 2a, so that it is folded towards the upper part forming seat of the seat structure 3a.
Il est possible de prévoir une poignée comme moyen de commande de déverrouillage sur le côté latéral de la structure de dossier 2a ainsi que le même mécanisme de commande de déverrouillage de chaque côté latéral de la structure d'assise 3a.It is possible to provide a handle as an unlocking control means on the lateral side of the backrest structure 2a and the same unlocking control mechanism on each lateral side of the seat structure 3a.
Pendant l'escamotage de la structure de dossier 2a, le pion 8a porté par le flasque 11 et donc solidaire du dossier coulisse dans la lumière 8b de l'élément 21. La mise en seconde position d'escamotage et le verrouillage dans cette position par le dispositif 1 selon l'invention va maintenant être décrit, principalement en regard de la figure 2.During the retraction of the backrest structure 2a, the pin 8a carried by the flange 11 and thus secured to the backrest slides in the light 8b of the element 21. The setting second retraction position and locking in this position by the device 1 according to the invention will now be described, mainly with regard to FIG.
Comme il est vu à cette figure 2, le verrouillage de la structure de dossier 2a est effectué, au moins sur un côté latéral de la structure d'assise 3a, par l'action de l'élément 21. Cet élément 21 est bloqué, à sa première extrémité, par la coopération de sa lumière 8b avec le pion 8a du flasque 11 et, à son autre extrémité, par la coopération de la tête 20a de crochet 20 avec son pion 21a de verrouillage.As seen in this FIG. 2, the locking of the backrest structure 2a is performed, at least on one lateral side of the seat structure 3a, by the action of the element 21. This element 21 is blocked, at its first end, by the cooperation of its light 8b with the pin 8a of the flange 11 and, at its other end, by the cooperation of the hook head 20a 20 with its locking pin 21a.
Avantageusement, une butée d'angle présente à chaque extrémité de l'axe Al limite le débattement angulaire de la structure de dossier 2a.Advantageously, an angle stop at each end of the axis Al limits the angular displacement of the backrest structure 2a.
Pour assurer un blocage en position d'escamotage, l'élément 21 est entraîné en pivotement autour de son axe central A3 par l'intermédiaire de sa lumière 8b dans laquelle coulisse le pion 8a appartenant au flasque 11.To ensure a locking in the retracted position, the element 21 is pivotally driven about its central axis A3 through its light 8b in which slides the pin 8a belonging to the flange 11.
Quand la structure de dossier 2a et le flasque 11 en forme d'équerre pivotent dans le sens de la flèche Fl de la figure 1 autour de l'axe Al de pivotement du flasque 11, l'élément 21 pivote dans le sens de la flèche F2 autour de son axe de pivotement A3, comme montré à la figure 2.When the backrest structure 2a and the flange 11 in the form of bracket rotate in the direction of the arrow Fl of Figure 1 about the pivotal axis A1 of the flange 11, the element 21 pivots in the direction of the arrow F2 about its pivot axis A3, as shown in Figure 2.
En fin de course d'escamotage, le pion 8a du flasque 11 entraînant l'élément 21 a permis le pivotement de ce dernier. Le pion 21a de verrouillage, porté par l'extrémité de l'élément 21 opposée à celle portant la lumière 8b, se verrouille alors dans la tête 20a du crochet 20. Cet élément 21, ainsi verrouillé, maintient la structure 2a de dossier dans sa position escamotée, cette position étant la seconde position de verrouillage selon la présente invention.At the end of the retraction stroke, the pin 8a of the flange 11 driving the element 21 allowed the pivoting of the latter. The lock pin 21a, carried by the end of the element 21 opposite the one carrying the light 8b, then locks in the head 20a of the hook 20. This element 21, thus locked, maintains the backrest structure 2a in its retracted position, this position being the second locking position according to the present invention.
Par exemple, dans la position d'escamotage, montrée à la figure 2, la structure de dossier 2a peut s'étendre de manière plus ou moins inclinée vers la structure d'assise 3a. Ceci peut être ajusté par les paramètres de l'élément 21, notamment sa longueur, sa forme et/ou la longueur de sa lumière 8b. II est aussi possible de rabattre plus la structure de dossier 2a contre la structure d'assise 3a que montré à la figure 2, le cas échéant en pouvant appliquer celle- ci contre la face supérieure de la structure d'assise 3a.For example, in the retracted position, shown in Figure 2, the backrest structure 2a may extend more or less inclined towards the seat structure 3a. This can be adjusted by the parameters of the element 21, in particular its length, its shape and / or the length of its light 8b. It is also possible to fold more the backrest structure 2a against the seat structure 3a that shown in Figure 2, if necessary by being able to apply it against the upper face of the seat structure 3a.
Pour revenir en position initiale, le dispositif d'escamotage 1 à au moins deux positions de verrouillage est à déverrouiller de sa position escamotée par l'utilisation de l'élément de commande, comme une poignée, agissant sur le câble 5 qui fait de nouveau basculer au moins un crochet 20 autour de son axe A4 de pivotement et libère le pion 21a de l'élément 21 du contact avec la tête 20a dudit crochet 20.To return to the initial position, the retraction device 1 with at least two locking positions is to be unlocked from its retracted position by the use of the control element, like a handle, acting on the cable 5 which is again to swing at least one hook 20 about its axis A4 of pivoting and releases the pin 21a of the element 21 from contact with the head 20a of said hook 20.
La structure de dossier 2a est alors pivotée dans le sens contraire de la flèche Fl de la figure 1 et retrouve sa position normale d'utilisation dans laquelle elle est à nouveau verrouillée par la coopération du premier moyen de verrouillage 6 du flasque latéral 11 avec le crochet 20 de la structure d'assise 3a.The backrest structure 2a is then rotated in the opposite direction of the arrow F1 in FIG. 1 and returns to its normal position of use in which it is locked again by the cooperation of the first locking means 6 of the lateral flange 11 with the hook 20 of the seat structure 3a.
L'avantage majeur de la présente invention est de regrouper deux verrouillages, chacun dans une position différente dans un seul dispositif d'escamotage, ce qui procure un gain de place et de pièces à mettre en oeuvre pour effectuer ces verrouillages. De plus, le moyen complémentaire de verrouillage porté par la structure d'assise est commun pour les deux verrouillages.The major advantage of the present invention is to group two locks, each in a different position in a single retraction device, which provides a saving of space and parts to implement to perform these locks. In addition, the complementary locking means carried by the seat structure is common for both locks.
Une modularité aisée des sièges d'un véhicule automobile est ainsi obtenue. Cela ne nécessite qu'un procédé d'escamotage et un verrouillage en position simples de fonctionnement.Easy modularity of the seats of a motor vehicle is thus obtained. This only requires a method of retraction and locking in simple operating position.
Un tel siège avec dossier escamotable selon la présente invention permet aussi de maintenir valide tous les réglages existants de siège, ceux-ci étant à commande mécanique ou électrique.Such a seat with retractable backrest according to the present invention also keeps valid all existing seat settings, they being mechanically or electrically controlled.
Le réglage de dossier peut ainsi rester traditionnel ainsi que son verrouillage et sa commande, ce qui représente une simplification des adaptations à entreprendre pour l'utilisation d'un tel siège selon la présente invention. L'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemples. The backrest adjustment can thus remain traditional and its locking and control, which represents a simplification of the adaptations to be undertaken for the use of such a seat according to the present invention. The invention is in no way limited to the described and illustrated embodiments which have been given by way of example only.
