Description

S I EG E D E VE H I C U LE MO D U LAI R E  S I EG E D E VE H I C U THE LA R DA T
La présente invention concerne de manière générale un siège de véhicule modulaire et plus particulièrement en un dossier de siège pivotant monté sur un véhicule automobile. The present invention generally relates to a modular vehicle seat and more particularly to a pivoting seat back mounted on a motor vehicle.
Il est connu dans l'art antérieur des sièges de véhicule automobile agencés pour permettre d'une part le transport de passagers assis, et d'autre part pouvant se rabattre pour permettre le chargement d'objets volumineux dans le véhicule. Un tel siège est notamment décrit dans le document FR2897565. Ce siège comporte une assise et un dossier. Lors de l'utilisation du siège pour transporter un passager assis, l'assise et le dossier sont en position normale d'utilisation, à savoir l'assise est sensiblement horizontale et le dossier est quant à lui sensiblement vertical. Pour permettre d'augmenter le volume de chargement si des objets longs ou volumineux doivent être transportés à l'aide du véhicule, le siège peut être agencé en position repliée, telle que représentée à la Figure 6. Pour passer de la position normale d'utilisation à la position repliée, l'assise pivote entre une position sensiblement horizontale et une position sensiblement verticale au milieu du véhicule, le pivotement se faisant autour d'un axe longeant le côté latéral intérieur du siège. Ensuite, le dossier pivote autour d'un axe horizontal longeant le bord inférieur du dossier, entre la sensiblement verticale d'utilisation et une position repliée, vers l'avant.  It is known in the prior art motor vehicle seats arranged to allow on the one hand the transport of seated passengers, and secondly can be folded to allow the loading of bulky objects in the vehicle. Such a seat is described in particular in the document FR2897565. This seat has a seat and a backrest. When using the seat to transport a seated passenger, the seat and the backrest are in the normal position of use, namely the seat is substantially horizontal and the backrest is substantially vertical. To increase the load volume if long or bulky objects are to be transported by the vehicle, the seat can be arranged in the folded position, as shown in Figure 6. To move from the normal position of use in the folded position, the seat pivots between a substantially horizontal position and a substantially vertical position in the middle of the vehicle, the pivoting being around an axis along the inner lateral side of the seat. Then, the backrest pivots about a horizontal axis running along the bottom edge of the backrest, between the substantially vertical use and a folded position, forwards.
Toutefois, un tel siège présente plusieurs inconvénients. Le premier est de ne pas permettre le pliage du dossier sans mettre préalablement l'assise en position de cloisonnement longitudinal. On ne peut pas faire passer le siège de sa position normale d'utilisation en sa position repliée sans avoir déplacé au préalable l'assise, de manière à pouvoir pivoter le dossier dans la position repliée vers l'avant. Par ailleurs, l'assise de ce siège est mobile. Il en découle que la complexité du siège en est augmentée car il faut prévoir des axes de pivotement sur l'assise, l'assise ne pouvant pas non plus être commune à deux sièges située côte à côte dans le cas de sièges arrières par exemple. Il en résulte que les coûts de fabrication d'assises selon ce modèle sont élevés. Enfin, il faut noter que la mise en configuration du siège en position repliée est fastidieuse, car il faut préalablement mettre en position de cloisonnement longitudinal l'assise d'une part et une fois cette opération réalisée, il faut ensuite mettre en position repliée vers l'avant le dossier d'autre part. However, such a seat has several disadvantages. The first is not to allow the folding of the folder without putting the seat before the position of longitudinal partitioning. The seat can not be moved from its normal position of use to its folded position without first moving the seat, so that the seatback can be pivoted to the folded position forward. Moreover, the seat of this seat is mobile. It follows that the complexity of the seat is increased because it must provide pivoting axes on the seat, the seat can not more common to two seats located side by side in the case of rear seats for example. As a result, the costs of manufacturing seats according to this model are high. Finally, it should be noted that the setting configuration of the seat in the folded position is tedious, because it must first put in longitudinal partitioning position the seat on the one hand and once this operation done, it must then put in the folded position to the front the file on the other hand.
Un but de la présente invention est de répondre aux inconvénients du document de l'art antérieur mentionné ci-dessus et en particulier, tout d'abord, de fournir un siège modulaire pour véhicule permettant d'améliorer l'ergonomie pour permettre d'une part de charger des objets longs ou encombrants et permettre d'autre part de cloisonner longitudinalement le véhicule. Un tel siège, avec une ergonomie améliorée, permet à l'utilisateur de mettre en configuration simplement le véhicule pour répondre à ses besoins et en outre réduit la complexité technique de réalisation du dossier et de l'assise, ce qui permet de réduire les coûts.  An object of the present invention is to meet the disadvantages of the prior art document mentioned above and in particular, first of all, to provide a modular vehicle seat for improving the ergonomics to enable a to load long objects or bulky and also to partition the vehicle longitudinally. Such a seat, with improved ergonomics, allows the user to simply configure the vehicle to meet its needs and further reduces the technical complexity of achieving the backrest and seat, which reduces costs .
Pour cela un premier aspect de l'invention concerne un siège de véhicule comprenant un dossier apte à pivoter entre une position normale d'utilisation et une position repliée vers l'avant, autour d'un premier axe horizontal, caractérisé en ce que le dossier est aussi apte à pivoter, entre la position normale d'utilisation et une position de cloisonnement longitudinal du véhicule, autour d'un deuxième axe contenu dans un plan perpendiculaire au premier axe. De cette manière, on simplifie la fabrication de l'assise, car il n'y a plus besoin de la rendre mobile par rapport au véhicule pour obtenir le cloisonnement longitudinal au moyen du véhicule. De plus, la mise en configuration du véhicule pour pouvoir charger des objets longs ou volumineux est simple, il n'y a que le dossier à faire pivoter. En outre, le dossier en position verticale offrant un cloisonnement dans le sens longitudinal du véhicule, cela permet d'apporter une protection au passager assis sur le siège situé à côté. De préférence, le dossier du siège est apte à pivoter vers l'avant dudit siège, de manière à venir sur le côté de l'assise dudit siège. For this purpose, a first aspect of the invention concerns a vehicle seat comprising a backrest capable of pivoting between a normal use position and a forwardly folded position, around a first horizontal axis, characterized in that the backrest is also rotatable, between the normal position of use and a longitudinal partitioning position of the vehicle, about a second axis contained in a plane perpendicular to the first axis. In this way, it simplifies the manufacture of the seat, because there is no longer need to make it mobile relative to the vehicle to obtain the longitudinal partitioning by means of the vehicle. In addition, the configuration of the vehicle to be able to load long or bulky objects is simple, there is only the folder to rotate. In addition, the upright backrest providing a partition in the longitudinal direction of the vehicle, it provides protection to the passenger sitting in the seat next door. Preferably, the seat back is able to pivot towards the front of said seat, so as to come to the side of the seat of said seat.
De manière avantageuse, le deuxième axe longe le bord latéral du dossier situé du côté intérieur du véhicule. Cet agencement permet d'assurer la cinématique du mouvement du dossier par un mécanisme simple.  Advantageously, the second axis runs along the lateral edge of the backrest located on the inside of the vehicle. This arrangement makes it possible to ensure the kinematics of the movement of the backrest by a simple mechanism.
De manière avantageuse, le siège comporte un premier moyen de verrouillage du dossier sur le véhicule et en ce que le déverrouillage du premier moyen de verrouillage permet le pivotement du dossier autour du premier axe. Cela permet par une seule action de déverrouiller le dossier pour le faire passer de la position normale d'utilisation à la position repliée vers l'avant.  Advantageously, the seat comprises a first means of locking the backrest on the vehicle and in that the unlocking of the first locking means allows the folder to pivot about the first axis. This allows a single action to unlock the folder to move from the normal position of use to the folded position forward.
De manière avantageuse, le siège comporte un deuxième moyen de verrouillage du dossier sur le véhicule et le déverrouillage du premier et du deuxième moyen de verrouillage verrouille le pivotement autour du premier axe et permet le pivotement du dossier autour du deuxième axe. Ainsi, grâce à cet agencement, lorsque tous les moyens de verrouillage sont déverrouillés, le dossier peut pivoter uniquement autour du deuxième axe pendant la mise en place du dossier en position de cloisonnement longitudinal du véhicule est aisée, le dossier n'ayant qu'un degré de liberté.  Advantageously, the seat comprises a second means of locking the backrest on the vehicle and the unlocking of the first and second locking means locks pivoting about the first axis and allows the pivoting of the backrest around the second axis. Thus, thanks to this arrangement, when all the locking means are unlocked, the backrest can pivot only around the second axis during the installation of the backrest in longitudinal partitioning position of the vehicle is easy, the file having only one degree of freedom.
De manière avantageuse, le dossier est apte à pivoter autour du deuxième axe par l'intermédiaire d'une chape montée en pivot sur un support fixé au véhicule. On comprendra par chape une pièce portant un axe de rotation. Cette réalisation simple permet de n'avoir pas d'autre pièce intermédiaire entre le châssis du véhicule et le dossier.  Advantageously, the backrest is pivotable about the second axis by means of a clevis pivotally mounted on a support fixed to the vehicle. It will be understood by clevis a part carrying an axis of rotation. This simple embodiment makes it possible to have no other intermediate piece between the chassis of the vehicle and the backrest.
De manière avantageuse, le dossier est apte à pivoter autour du premier axe par l'intermédiaire d'un axe monté en pivot sur la chape montée en pivot sur un support fixé au véhicule. Ainsi, le dossier est solidaire de la chape pour pivoter autour du deuxième axe, tout en pouvant pivoter autour d'un axe porté par la chape. On comprend que cette réalisation astucieuse évite de compliquer la conception du dossier, car le premier axe est porté par la chape, qui elle même permet le pivotement du dossier autour du deuxième axe dans la mesure où elle est montée en pivot par rapport à un support fixé au véhicule. Advantageously, the backrest is pivotable about the first axis by means of an axle pivotally mounted on the yoke pivotally mounted on a support fixed to the vehicle. Thus, the backrest is secured to the yoke to pivot about the second axis, while being pivotable about an axis carried by the yoke. We understand that this clever realization avoids complicating the design of the folder, because the first axis is supported by the clevis, which itself allows the pivoting of the backrest around the second axis to the extent that it is pivotally mounted relative to a support attached to the vehicle.
De manière avantageuse, le déverrouillage du deuxième moyen de verrouillage solidarise le dossier du siège avec la chape montée en pivot sur un support fixé au véhicule. Ce mode de réalisation pour bloquer la rotation du dossier autour du premier axe qui ne met en jeu que la chape est simple car il n'y a pas de pièce de solidarisation fixe par rapport au châssis du véhicule. Tous les moyens impliqués pour solidariser le dossier avec la chape sont embarqués sur le dossier. Une fois la chape solidarisée avec le dossier, il reste uniquement un degré de liberté de rotation autour du deuxième axe. Il ne peut plus y avoir de mouvement relatif entre la chape et le dossier.  Advantageously, the unlocking of the second locking means secures the seat back with the clevis pivotally mounted on a support fixed to the vehicle. This embodiment to block the rotation of the backrest around the first axis which involves only the yoke is simple because there is no fixed piece of fastening relative to the vehicle frame. All the means involved to secure the file with the screed are embedded on the file. Once the clevis is secured with the backrest, there remains only one degree of freedom of rotation around the second axis. There can no longer be any relative movement between the clevis and the backrest.
De manière avantageuse, la chape est en forme d'équerre. Cette mise en œuvre permet de simplifier au maximum la chape, ce qui en limite les coûts de fabrication.  Advantageously, the yoke is square-shaped. This implementation makes it possible to simplify the screed as much as possible, which limits the manufacturing costs.
De manière avantageuse, le deuxième moyen de verrouillage comporte trois éléments, un verrou apte à verrouiller le dossier sur le véhicule, une barre de liaison et un crochet, ces trois éléments étant reliés par une liaison rigide, et en ce que le verrou, la barre de liaison et le crochet sont agencés pour que le déverrouillage du verrou solidarise par l'intermédiaire du crochet le dossier du siège avec la chape montée en pivot sur un support fixé au plancher du véhicule. Cette liaison rigide entre le verrou et le crochet par l'intermédiaire de la barre de liaison garantit que le dossier ne peut pas être désolidarisé du véhicule sans empêcher la rotation du dossier autour du premier axe. Cet agencement est gage de sécurité, le dossier ne pouvant pivoter qu'autour d'un axe à la fois. De plus, d'un point de vue ergonomique cela permet à l'opérateur de n'avoir qu'une action à effectuer pour mettre le dossier en position de cloisonnement longitudinal du véhicule. Un second aspect de l'invention est un véhicule automobile comportant au moins un siège selon le premier aspect de l'invention. Advantageously, the second locking means comprises three elements, a lock adapted to lock the backrest on the vehicle, a connecting bar and a hook, these three elements being connected by a rigid connection, and in that the lock, the connecting bar and the hook are arranged so that the unlocking of the lock secures by means of the hook the seat back with the yoke pivotally mounted on a support fixed to the floor of the vehicle. This rigid connection between the latch and the hook via the connecting bar ensures that the backrest can not be detached from the vehicle without preventing rotation of the backrest around the first axis. This arrangement is a guarantee of security, since the backrest can only pivot about one axis at a time. In addition, from an ergonomic point of view, it allows the operator to have only one action to perform to put the folder in longitudinal partitioning position of the vehicle. A second aspect of the invention is a motor vehicle comprising at least one seat according to the first aspect of the invention.

La figure 1 représente deux sièges et un banquette de véhicule dont un siège 1 , vu de l'avant du véhicule, comporte un dossier 10 et une assise 20. Le dossier est représenté en position pivoté vers l'avant pour permettre le chargement d'objets longs ou volumineux. Le pivotement se fait autour du premier axe de rotation représenté par l'axe imaginaire en trait mixte 30.  FIG. 1 represents two seats and a vehicle seat, of which a seat 1, seen from the front of the vehicle, has a backrest 10 and a seat 20. The backrest is shown in a pivoted position forward to allow the loading of long or bulky objects. Pivoting is around the first axis of rotation represented by the imaginary axis in dotted line 30.
Sur la figure 2, le dossier 10 du siège 1 est représenté en position de cloisonnement longitudinal du véhicule. Pour arriver en position de cloisonnement longitudinal du véhicule, le dossier a pivoté autour du deuxième axe de rotation représenté par l'axe imaginaire en trait mixte 40.  In FIG. 2, the backrest 10 of the seat 1 is shown in the longitudinal partitioning position of the vehicle. To arrive in longitudinal partitioning position of the vehicle, the backrest has rotated about the second axis of rotation represented by the imaginary axis in dotted line 40.
La figure 3 représente le siège 1 , vu de l'arrière du véhicule, avec le dossier 10 en position de cloisonnement longitudinal du véhicule. A cet effet, le dossier 10 a pivoté autour du deuxième axe 40. Pour permettre le pivotement du dossier autour du deuxième axe 40, un premier moyen de verrouillage comportant un verrou 1 1 a été déverrouillé. De plus, un deuxième moyen de verrouillage comportant un verrou 12 a aussi été déverrouillé. Lors du déverrouillage du deuxième moyen de verrouillage, le pivotement du dossier 10 autour du premier axe 30 a été verrouillé, de sorte que le dossier ne peut pas pivoter autour de ce premier axe 30.

In addition, a second locking means having a latch 12 has also been unlocked. When unlocking the second locking means, the pivoting of the backrest 10 about the first axis 30 has been locked, so that the backrest can not pivot about this first axis 30. The latch 12 of the second locking means is integral with a connecting bar 13 which is connected at its other end with a hook 14.
La figure 4 représente un détail du siège des figures 1 à 3 en position normale d'utilisation. Le premier axe de rotation 30a est monté en pivot dans une chape 60 qui a la forme d'une équerre. Lors du pivotement du dossier entre la position normale d'utilisation et la position repliée vers l'avant, l'axe 30 pivote dans la chape 60. La chape 60 peut elle même tourner autour du deuxième axe 40 de rotation, elle est montée en pivot sur le support 55 qui est fixé au châssis du véhicule 50.  Figure 4 shows a detail of the seat of Figures 1 to 3 in the normal position of use. The first axis of rotation 30a is pivotally mounted in a yoke 60 which has the shape of a square. When pivoting the backrest between the normal position of use and the folded position forward, the axis 30 pivots in the yoke 60. The yoke 60 itself can turn about the second axis 40 of rotation, it is mounted in pivot on the support 55 which is fixed to the frame of the vehicle 50.
La figure 5 représente le même détail du siège 1 que la figure 4, mais sur cette figure, le dossier 10 est en position de cloisonnement longitudinal du véhicule. Le dossier 10 a pivoté autour de l'axe 40. Pour permettre un pivotement aisé du dossier 10 autour du deuxième axe 40, lors du déverrouillage du deuxième moyen de verrouillage, le crochet 14 a solidarisé le dossier 10 avec la chape 60 en pénétrant dans un trou 65 ménagé dans la chape 60. Ainsi, le dossier 10 étant solidaire de la chape 60, le pivotement autour de l'axe 40 se fait par l'intermédiaire de la chape 60.  Figure 5 shows the same detail of the seat 1 as Figure 4, but in this figure, the backrest 10 is in longitudinal partitioning position of the vehicle. The backrest 10 has pivoted about the axis 40. To allow easy pivoting of the backrest 10 around the second axis 40, when unlocking the second locking means, the hook 14 secured the backrest 10 with the yoke 60 by penetrating into the seat. a hole 65 formed in the yoke 60. Thus, the backrest 10 being integral with the yoke 60, the pivoting about the axis 40 is via the yoke 60.
