Description

La présente invention concerne un dispositif de commande pour siege de véhicule à dossier orientable. The present invention relates to a control device for a vehicle seat with an adjustable backrest.

I1 est maintenant bien connu de realiser des sièges de véhicule à dossier orientable, le dossier pouvant être verrouillé dans plusieurs positions d'inclinaisons différentes. I1 is now well known to make vehicle seats with adjustable backrest, the backrest being able to be locked in several different tilt positions.

Par ailleurs, on sait que lorsque le siege est transformable en couchette à deux niveaux, il est nécessaire de mettre le dossier en position redressée pour pouvoir maintenir la couchette supérieure en position horizontale. Furthermore, we know that when the seat can be transformed into a two-level berth, it is necessary to put the backrest in the upright position in order to be able to maintain the upper berth in a horizontal position.

Lorsqu'un véhicule comportant un grande nombre de sièges à dossier orientable a éte utilise dans la configuration de sieges et doit etre préparé en configuration de couchettes il est donc nécessaire qu'un operateur mette tous les dossiers en position redressée avant de transformer les sièges en couchettes.When a vehicle with a large number of seats with adjustable backrest has been used in the seat configuration and must be prepared in the berth configuration, it is therefore necessary for an operator to put all the backrests in the upright position before transforming the seats into berths.

Cette manipulation des dossiers est généralement pénible pour 1 'opérateur en raison du caractère peu accessible de l'organe de commande du dispositif de commande de l'orientation de chaque dossier. De plus, lorsque le véhicule comporte des sièges jumelés, c'est-à-dire comportant une assise commune et des dossiers orientables individuels, il est nécessaire que l'opérateur pénètre dans les rangées de sièges pour atteindre l'organe de commande des sièges qui ne sont pas immédiatement contigus à une allée. This handling of the files is generally painful for the operator because of the inaccessibility of the control member of the device for controlling the orientation of each file. In addition, when the vehicle has twin seats, that is to say comprising a common seat and individual adjustable backrests, it is necessary for the operator to enter the rows of seats in order to reach the seat control member. that are not immediately adjacent to an aisle.

Cette manipulation entraîne donc une perte de temps importante et augmente d'autant le coût de gestion du véhicule.This manipulation therefore results in a significant loss of time and therefore increases the cost of managing the vehicle.

Un but de la présente invention est de proposer un dispositif de commande pour siège de véhicule à dossier orientable qui puisse être manoeuvré facilement par un operateur et qui, dans le cas de sièges jumelés, permette de redresser l'ensemble des dossiers des sieges jumelés par une manipulation unique.  An object of the present invention is to provide a control device for a vehicle seat with an adjustable backrest which can be easily maneuvered by an operator and which, in the case of twin seats, makes it possible to straighten all the files of the seats paired by a unique manipulation.

En vue de la réalisation de ce but, on prévoit, selon l'invention, un dispositif de commande pour siège de véhicule à dossier orientable comportant une assise articulée à un châssis et un dossier également articulé au châssis, ce dispositif de commande comportant des moyens de rappel du dossier vers une position redresse, des moyens de verrouillage du dossier dans au moins une position inclinée et un organe de commande des moyens de verrouillage, caractérisé en ce qu'il comporte des moyens de déverrouillage automatique disposés pour laisser libre la manoeuvre de l'organe de commande lorsque l'assise est dans une position de siege et pour agir sur l'organe de commande dans le sens du déverrouillage lorsque l'assise est relevée. In order to achieve this goal, there is provided, according to the invention, a control device for a vehicle seat with an adjustable backrest comprising a seat articulated to a chassis and a backrest also articulated to the chassis, this control device comprising means for returning the file to a straightened position, means for locking the file in at least one inclined position and a member for controlling the locking means, characterized in that it comprises automatic unlocking means arranged to allow the operation of the control member when the seat is in a seat position and to act on the control member in the unlocking direction when the seat is raised.

Ainsi, dans la position de siège de l'assise, l'utilisateur est libre de régler l'inclinaison de son dossier comme il l'entend et de verrouiller le dossier dans l'inclinaison choisie, tandis qu'un operateur externe peut mettre le dossier en position redressée en manoeuvrant simplement 1 'assise des sièges, ce qui est généralement plus simple que d'accéder à l'organe de commande du dispositif de commande. Thus, in the seat position of the seat, the user is free to adjust the inclination of his backrest as he sees fit and to lock the backrest in the chosen inclination, while an external operator can put the backrest in the upright position by simply operating the seat base, which is generally simpler than accessing the control member of the control device.

Selon une version avantageuse de l'invention, les moyens de déverrouillage automatique comprennent un organe d'action disposé au voisinage de l'organe de commande et des moyens de rappel de l'organe d'action pour solliciter celui-ci vers un contact avec l'organe de commande dans le sens du déverrouillage des moyens de verrouillage du dossier, l'organe d'action étant en outre disposé par rapport à l'assise pour être sollicité par celle-ci à l'encontre des moyens de rappel de l'organe d'action lorsque l'assise est en position de siège. Ainsi, l'organe d'action est maintenu en permanence en contact avec 1 'assise par les moyens de rappel de l'organe d'action et le déverrouillage automatique est obtenu dès que 1 'assise est relevée d'une façon suffisante pour l'actionnement de l'organe de commande. According to an advantageous version of the invention, the automatic unlocking means comprise an action member disposed in the vicinity of the control member and means for returning the action member to urge the latter towards contact with the control member in the direction of unlocking the file locking means, the action member being further arranged relative to the seat to be urged by the latter against the return means of the action body when the seat is in the seat position. Thus, the action member is kept permanently in contact with the seat by the return means of the action member and the automatic unlocking is obtained as soon as the seat is raised sufficiently for the actuation of the control member.

Selon un mode de réalisation préfere de l'invention l'organe de commande est un levier allongé, disposé sous un montant du châssis du siège et l'organe d'action est un boulon comportant une tige s'étendant à travers le montant sensiblement perpendiculairement à l'organe de commande et une tête dirigée vers 1 'assise du siège, et les moyens de rappel de l'organe d'action comportent un ressort de compression dispose entre la tête du boulon et le montant du châssis. Ainsi, l'organe de commande du d-ispositif de commande peut être manoeuvré librement tant que l'assise du siège repose sur la tête du boulon. Le but de l'invention est donc atteint au moyen d'une structure très simple. According to a preferred embodiment of the invention, the control member is an elongated lever, disposed under an upright of the seat frame and the action member is a bolt comprising a rod extending through the upright substantially perpendicularly to the control member and a head directed towards the seat, and the return means of the action member comprise a compression spring disposed between the head of the bolt and the amount of the chassis. Thus, the control member of the control device can be operated freely as long as the seat cushion rests on the head of the bolt. The object of the invention is therefore achieved by means of a very simple structure.

Selon une application avantageuse de l'invention, à un siège comportant plusieurs dossiers orientables individuellement et une assise commune, chaque dossier comporte un dispositif de commande individuel comprenant des moyens de déverrouillage automatique disposés en regard de l'assise commune. Ainsi, par une seule manoeuvre de l'assise commune, on obtient le déverrouillage de l'ensemble des dispositifs de commande de l'orientation des dossiers individuels et donc le redressement del'ensemble des dossiers. According to an advantageous application of the invention, to a seat comprising several individually adjustable backrests and a common seat, each backrest comprises an individual control device comprising automatic unlocking means arranged opposite the common seat. Thus, by a single operation of the common seat, the unlocking of all of the devices for controlling the orientation of the individual files is obtained and therefore the recovery of all the files.

D'autres caractéristiques et avantages de 1 'inven- tion résulteront encore de la description ci-après d'un exemple non limitatif en référence aux dessins annexés dans lesquels
- la figure 1 est une vue de côte, partiellement en coupe, d'un siège de véhicule à dossier orientable équipé du dispositif de commande selon l'invention,
- la figure 2 est une vue de dessus de l'organe de commande et des moyens de déverrouillage partiellement en coupe selon le plan II-II delta figure 1,
- la figure 3 est une vue analogue a celle de la figure 1 dans une position différente des éléments constitubants.
Other characteristics and advantages of the invention will also result from the following description of a nonlimiting example with reference to the accompanying drawings in which
FIG. 1 is a side view, partially in section, of a vehicle seat with an adjustable backrest equipped with the control device according to the invention,
FIG. 2 is a top view of the control member and of the unlocking means partially in section along the plane II-II delta in FIG. 1,
- Figure 3 is a view similar to that of Figure 1 in a different position of the constituent elements.

En référence aux figures, le siege de vehicule à dossier orientable comporte d'une façon connue en soi un châssis 1 raccorde à la caisse du véhicule (par des moyens non représentés) supportant d'une part une assise 2 articulée au châssis autour d'un axe 3 et un dossier orientable 4 également supporté par le châssis et articulé autour d'un axe 5. With reference to the figures, the vehicle seat with adjustable backrest comprises in a manner known per se a chassis 1 connected to the vehicle body (by means not shown) supporting on the one hand a seat 2 articulated to the chassis around an axis 3 and an adjustable backrest 4 also supported by the chassis and articulated around an axis 5.

Le dispositif de commande de l'orientation du dossier 4 comporte des moyens de rappel du dossier vers une position redressée et des moyens de verrouillage du dossier dans au moins une position inclinée. Dans le mode de réalisation représenté, les moyens de rappel et les moyens de verrouillage sont réalisés par un vérin -à gaz 6 dont le corps 7 est relie au dossier 4 par une articulation 8 et dont la tige 9 passe à travers un arbre 10 monté de façon articulee sur le châssis 1 et est fixée à cet arbre. Le vérin à gaz 6 comporte également un bouton de commande 11 coaxial à la tige 9 selon unestructure connue en soi de sorte qu'au repos il fait saillie par rapport à l'extrémité de la tige 9 opposée au corps 7 du vérin 6. The backrest orientation control device 4 comprises means for returning the backrest to a straightened position and means for locking the backrest in at least one inclined position. In the embodiment shown, the return means and the locking means are produced by a gas cylinder 6 whose body 7 is connected to the backrest 4 by a hinge 8 and whose rod 9 passes through a shaft 10 mounted articulated on the frame 1 and is fixed to this shaft. The gas spring 6 also comprises a control button 11 coaxial with the rod 9 according to a structure known per se so that at rest it projects relative to the end of the rod 9 opposite the body 7 of the cylinder 6.

Le dispositif de commande comporte egalement
un organe de commande 12 se présentant sous la forme d'un levier allongé, et plus précisément une tige 13 montée à l'une de ses extrémités sur un axe 14 dont les extrémites
sont engagées dans des bossages (non représentés) solidaires
du châssis 1. Au voisinage de l'axe 14, l'organe de commande 12 comporte une butee 15 en regard du bouton de commande 11
du vérin à gaz 6. L'organe de commande 12 comporte egalement
un oeillet 16 solidaire de la tige 13 et s'étendant sur
le coté de celle-ci. La tige 13 de l'organe de commande 12
s 'étend généralement sous un montant latéral 17 du châssis 1
du siège. Dans le mode de réalisation représenté, le montant
17 est un montant tubulaire de section carrée.
The control device also includes
a control member 12 in the form of an elongated lever, and more specifically a rod 13 mounted at one of its ends on an axis 14 whose ends
are engaged in integral bosses (not shown)
of the chassis 1. In the vicinity of the axis 14, the control member 12 comprises a stop 15 opposite the control button 11
of the gas spring 6. The control member 12 also comprises
an eyelet 16 integral with the rod 13 and extending over
the side of it. The rod 13 of the control member 12
generally extends under a lateral upright 17 of the chassis 1
from the headquarters. In the embodiment shown, the amount
17 is a tubular upright of square section.

Les moyens de déverrouillage automatique comprennent un organe d'action formé par un boulon 18 comprenant une tige 19 s'étendant à travers le montant 17 sensiblement perpendiculairement à l'organe de commande 12 et une tête 20 dirigée vers 1 'assise 2 du siège. Les moyens de déverrouillage automatique comprennent également des moyens de rappel du boulon 18 formés par un ressort helicoldal 21 entourant la tige 19 du boulon 18 et disposé entre la tête 20 du boulon 18 et la paroi inférieure du montant 17. La tige 19 et le ressort 21 s'étendent à travers une ouverture 22 réalisée dans la paroi supérieure du montant 17. A sa partie inferieure, le boulon 18 comporte un écrou 23 sur lequel s'appuie une rondelle 24 supportant l'oeillet 16 de l'organe de commande 12. The automatic unlocking means comprise an action member formed by a bolt 18 comprising a rod 19 extending through the upright 17 substantially perpendicular to the control member 12 and a head 20 directed towards the seat 2 of the seat. The automatic unlocking means also comprise means for returning the bolt 18 formed by a helical spring 21 surrounding the rod 19 of the bolt 18 and disposed between the head 20 of the bolt 18 and the bottom wall of the upright 17. The rod 19 and the spring 21 extend through an opening 22 made in the upper wall of the upright 17. At its lower part, the bolt 18 comprises a nut 23 on which a washer 24 bears the eyelet 16 of the control member 12 .

Le fonctionnement du dispositif est le suivant
Lorsque 1 'assise 2 est en position de siege, elle s'appuie sur la tête 20 du boulon 18 qui est maintenu enfoncé à 1 'encontre du ressort 21. Sous l'effet de son poids, l'organe de commande 12 repose sur la rondelle 24 comme représenté en traits pleins sur la figure 1 et la butee 15 est écartee de l'extrémité de la tige 9 du vérin 6.
The operation of the device is as follows
When the seat 2 is in the seat position, it rests on the head 20 of the bolt 18 which is held pressed against the spring 21. Under the effect of its weight, the control member 12 rests on the washer 24 as shown in solid lines in FIG. 1 and the stop 15 is moved away from the end of the rod 9 of the jack 6.

Le bouton de commande 11 est alors sorti et le vérin 6 est bloque.The control button 11 is then released and the actuator 6 is blocked.

Dans cette position, l'organe de commande 12 peut être librement manoeuvre par un utilisateur et, si celui-ci souhaite modifier l'orientation du dossier 4, il releve l'organe de commande 12 selon la position représentée en pointillés sur la figure 1, ce qui provoque 1 'enfon- cement du bouton de commande 11 du vérin 6 et donc le dé- blocage du vérin. L'utilisateur peut alors exercer une pression sur le haut du dossier 4 pour incliner celui-ci vers 1 'arrière.  In this position, the control member 12 can be freely operated by a user and, if the latter wishes to modify the orientation of the backrest 4, he raises the control member 12 according to the position shown in dotted lines in FIG. 1 , which causes the actuation of the control button 11 of the jack 6 and therefore the release of the jack. The user can then exert pressure on the top of the backrest 4 to tilt it backwards.

Lorsque l'utilisateur relâche l'organe de commande 12, celui-ci retombe contre la rondelle 24 et le vérin 6 est à nouveau bloqué dans la position désirée.  When the user releases the control member 12, it falls back against the washer 24 and the jack 6 is again locked in the desired position.

Lorsqu'on désire mettre le dossier en position redressée, par exemple en vue de transformer le siège en couchette à deux niveaux, on peut bien entendu manoeuvrer l'organe de commande 12 et le vérin 6 s'étend automatiquement sous l'effet du gaz sous pression qu'il contient. When it is desired to put the backrest in the upright position, for example in order to transform the seat into a two-level berth, it is of course possible to operate the control member 12 and the jack 6 extends automatically under the effect of gas under pressure it contains.

De façon alternative, on utilise les moyens de deverrouillage automatique selon l'invention en relevant l'assise 2 qui pivote autour de l'axe 3. Sous l'effet du ressort 21, le boulon 18 remonte alors dans la position représentée sur la figure 3 et dans ce mouvement il entraine la rondelle 24 qui agit sur l'organe de commande 12 pour relever celui-ci avec les effet décrits ci-dessus. Le disposi tif selon l'invention est particulièrement avantageux dans le cas de plusieurs sièges jumelés comportant une assise 2 commune et des dossiers séparés orientables individuellement, comportant chacun un dispositif de commande tel que décrit ci-dessus. Dans ce cas en effet, la manoeuvre de 1 'assise 2 provoque le redressement de l'ensemble des boulons 18 et donc le redressement de chacun des dossiers 4. Lorsque 1 'assise 2 est à nouveau abaissée, le bouton de commande 11 est relâché et chacun des dossiers 4 est verrouillé dans la position redressée. Alternatively, the automatic unlocking means according to the invention are used by raising the seat 2 which pivots about the axis 3. Under the effect of the spring 21, the bolt 18 then rises in the position shown in the figure 3 and in this movement it drives the washer 24 which acts on the control member 12 to raise it with the effects described above. The device according to the invention is particularly advantageous in the case of several twin seats comprising a common seat 2 and separate individually adjustable backrests, each comprising a control device as described above. In this case, in fact, the operation of the seat 2 causes the set of bolts 18 to straighten and therefore the straightening of each of the backrests 4. When the seat 2 is lowered again, the control button 11 is released and each of the files 4 is locked in the upright position.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit ci-dessus, et on peut y apporter des variantes d'exécution. Of course, the invention is not limited to the embodiment described above, and it is possible to make variant embodiments.

En particulier, le vérin 6 peut être remplacé par une structure comportant un ressort de rappel et des moyens de verrouillage séparés, par exemple une crémaillère coopérant avec un levier articulé portant un ergot de blocage. In particular, the jack 6 can be replaced by a structure comprising a return spring and separate locking means, for example a rack cooperating with an articulated lever carrying a locking pin.

De même, le boulon 18 peut etre remplacé par un levier articulé sur un montant du siège et coopérant avec les moyens de verrouillage du dossier pour liberer ceux-ci.  Likewise, the bolt 18 can be replaced by a lever articulated on an upright of the seat and cooperating with the means for locking the backrest to release them.
