Description

Siège pour véhicule automobile Seat for a motor vehicle

La présente invention concerne un siège pour véhicule automobile comportant une armature siège avec un dossier et une assise montée sur le plancher du véhicule de manière coulissante dans la direction longitudinale du véhicule. Un tel siège est connu par exemple de la demande de brevet français FR 2 757 463 Al. Les sièges avant des véhicules automobiles sont normalement montés sur le plancher du véhicule de manière coulissante dans la direction longitudinale du véhicule. Ceci permet d'adapter la position du siège à la morphologie d'un passager. Dans le cas des véhicules automobiles à trois portes, les sièges avant peuvent être équipés d'un dispositif permettant, en sortant du véhicule, d'avancer ou de basculer le siège avant pour libérer l'accès aux places arrière. The present invention relates to a seat for a motor vehicle comprising a seat frame with a backrest and a seat mounted on the floor of the vehicle slidably in the longitudinal direction of the vehicle. Such a seat is known for example from the French patent application FR 2 757 463 A1. The front seats of motor vehicles are normally mounted on the floor of the vehicle slidably in the longitudinal direction of the vehicle. This makes it possible to adapt the position of the seat to the morphology of a passenger. In the case of motor vehicles with three doors, the front seats may be equipped with a device allowing, when exiting the vehicle, to advance or tilt the front seat to release access to the rear seats.

Pour un véhicule à sept places qui sont disposés sur trois rangées, les sièges en deuxième rangée devant être avancés ou basculés pour libérer l'accès aux places en troisième rangée. Jusqu'à présent, les solutions à ce problème sont peu satisfaisantes car les sièges en deuxième rangée ne peuvent pas être dégagés suffisamment 20 de l'espace défini par la feuillure de porte. La demande de brevet français FR 2 757 463 Al propose un siège pour véhicule automobile comportant une armature siège avec un dossier et une assise, montés sur le plancher du véhicule de manière coulissante dans la direction longitudinale du véhicule au moyen d'une glissière 25 principale de positionnement de ce siège, disposée au-dessous de l'armature siège et s'étendant parallèlement à ladite direction longitudinale, un chariot intermédiaire de déplacement du siège étant interposé entre la glissière principale et l'armature siège. Cette construction permet l'accès aux places arrière d'un véhicule sans 30 obliger l'occupant de ce siège à descendre et permet à cet occupant de sortir plus facilement du véhicule. Cette solution est adaptée aux sièges avant d'un véhicule où l'espace devant le siège est assez important, For a seven-seater vehicle that is arranged in three rows, the seats in the second row to be advanced or tilted to free access to third-row seats. So far, the solutions to this problem are unsatisfactory since the second-row seats can not be released sufficiently from the space defined by the door rabbet. French patent application FR 2 757 463 A1 proposes a seat for a motor vehicle comprising a seat frame with a backrest and a seat, mounted on the floor of the vehicle slidably in the longitudinal direction of the vehicle by means of a main slide 25. positioning of this seat, disposed below the seat armature and extending parallel to said longitudinal direction, an intermediate carriage moving the seat being interposed between the main slide and the seat frame. This construction allows access to the rear seats of a vehicle without requiring the occupant of that seat to descend and allows this occupant to get out of the vehicle more easily. This solution is adapted to the front seats of a vehicle where the space in front of the seat is quite important,

permettant un mouvement avant sur une distance relativement grande. En deuxième rangée, il n'y a pas suffisamment d'espace devant les sièges pour effectuer la manoeuvre décrite ci-dessus. La demande de brevet français FR 2 474 409 Al décrit un siège de véhicule à assise et dossier mobiles. Ce siège est utilisable notamment dans des voitures de chemins de fer à compartiments. Des sièges décrits dans ce document peuvent être commodément nettoyés du fait que leur assise peut être relevée par simple pivotement. Ceci permet en outre d'agrandir l'espace disponible autour du siège et d'en faciliter l'accès. Ces sièges sont fixés sur le plancher du véhicule et reposent au niveau du dos contre une cloison du véhicule, par exemple. Ce type de siège ne se prête pas à l'utilisation en deuxième rangée d'une voiture à sept places car l'accès en troisième rangée ne peut pas être dégagé. L'invention a pour but d'éviter ces inconvénients décrits ci-dessus en proposant un siège pour véhicule automobile qui peut être efficacement dégagé de l'espace d'accès en troisième rangée d'un véhicule à 7 places. L'invention a pour objet un siège pour véhicule automobile comportant une armature siège avec un dossier et une assise montée sur le plancher du véhicule de manière coulissante dans la direction longitudinale du véhicule au moyen d'une glissière principale du positionnement de ce siège disposée au-dessous de l'armature siège et s'étendant parallèlement à ladite direction longitudinale, un chariot intermédiaire de déplacement du siège étant interposé entre la glissière principale et l'armature siège , l'assise est rabattable contre le dossier et le chariot intermédiaire comporte un rail fixe inférieur solidaire ou monobloc avec un rail mobile de la glissière principale et un rail mobile, sur laquelle l'armature siège est montée, l'armature sur son rail mobile peut glisser jusqu'à l'extrémité avant du rail fixe du chariot et le rail fixe du chariot peut glisser avec le rail mobile de la glissière principale au-delà de l'extrémité avant d'un rail fixe de la glissière principale, le chariot étant guidé et maintenu par son extrémité arrière en gardant son engagement dans le rail fixe de la glissière principale. allowing forward movement over a relatively large distance. In the second row, there is not enough space in front of the seats to perform the maneuver described above. French patent application FR 2 474 409 A1 describes a vehicle seat with movable seat and back. This seat can be used in particular in railway cars compartments. Seats described herein may be conveniently cleaned because their seating can be lifted by simply pivoting. This also makes it possible to enlarge the available space around the seat and to facilitate access to it. These seats are fixed on the floor of the vehicle and rest at the back against a partition of the vehicle, for example. This type of seat does not lend itself to second-row use of a seven-seater because third-row access can not be cleared. The object of the invention is to avoid these disadvantages described above by providing a seat for a motor vehicle that can be effectively removed from the third-row access space of a 7-seater vehicle. The invention relates to a seat for a motor vehicle comprising a seat frame with a backrest and a seat mounted on the vehicle floor slidably in the longitudinal direction of the vehicle by means of a main slide of the positioning of the seat disposed at below the seat armature and extending parallel to said longitudinal direction, an intermediate carriage moving the seat being interposed between the main slide and the seat frame, the seat is foldable against the backrest and the intermediate carriage comprises a fixed or integral monoblock fixed rail with a movable rail of the main slide and a movable rail, on which the seat frame is mounted, the frame on its movable rail can slide to the front end of the fixed rail of the carriage and the fixed rail of the carriage can slide with the movable rail of the main slide past the front end of a fixed rail of the a main slide, the carriage being guided and held by its rear end keeping its engagement in the fixed rail of the main slide.

Selon un mode de réalisation préféré, le parcours du chariot sur la glissière principale et le parcours de l'armature sur le chariot sont limités par des butées de fin de course. According to a preferred embodiment, the travel of the carriage on the main slide and the path of the armature on the carriage are limited by end stops.

Selon un autre mode de réalisation préféré, un renfort articulé sur l'extrémité avant du rail fixe du chariot supportant l'extrémité avant du rail fixe sur le plancher quand l'extrémité avant du rail fixe du chariot dépasse l'extrémité avant du rail fixe de la glissière principale dans la direction avant du véhicule. According to another preferred embodiment, a hinged reinforcement on the front end of the fixed rail of the carriage supporting the front end of the fixed rail on the floor when the front end of the fixed rail of the carriage exceeds the front end of the fixed rail of the main slide in the forward direction of the vehicle.

Selon une autre variante, l'extrémité libre du renfort est pourvue d'une roulette facilitant le mouvement du renfort sur le plancher. Selon une autre caractéristique, l'articulation du renfort avec le rail fixe du chariot est précontrainte par un ressort débloquant le renfort dès que le chariot dépasse avec son extrémité avant le rail fixe de la glissière principale, le renfort prenant appui sur le plancher. Selon un autre mode de réalisation préféré, le pivotement du renfort est limité par une butée de fin de course pour l'arrêter dans sa position support. Les caractéristiques et avantages de l'invention apparaîtront au cours de 20 la description qui va suivre, donnée à titre d'exemple et faisant référence aux dessins annexés, sur lesquels: Fig. 1 montre une vue de côté d'un mode de réalisation d'un siège pour véhicule automobile selon l'invention; Fig. 1-1 montre une vue détaillée des composants inférieurs du siège de 25 Fig. 1. Fig. 2 montre le siège selon Fig. 1 avec assise repliée; Fig. 3 montre le siège selon Fig. 2 avec chariot avancé; et Fig. 4 montre le siège selon Fig. 3 avec son armature, avancé sur le chariot. 30 Fig. 1 et Fig. 1-1 montrent une vue de côté d'un siège 1 d'un véhicule automobile disposé en deuxième rangée de siège d'un véhicule à sept According to another variant, the free end of the reinforcement is provided with a wheel facilitating the movement of the reinforcement on the floor. According to another characteristic, the articulation of the reinforcement with the fixed rail of the carriage is preloaded by a spring unlocking the reinforcement as soon as the carriage protrudes with its end before the fixed rail of the main slide, the reinforcement resting on the floor. According to another preferred embodiment, the pivoting of the reinforcement is limited by an end stop to stop in its support position. The features and advantages of the invention will become apparent from the following description given by way of example and with reference to the accompanying drawings, in which: FIG. 1 shows a side view of an embodiment of a seat for a motor vehicle according to the invention; Fig. 1-1 shows a detailed view of the lower components of the seat of FIG. 1. Fig. 2 shows the seat according to FIG. 1 with folded seat; Fig. 3 shows the seat according to FIG. 2 with advanced carriage; and 4 shows the seat according to FIG. 3 with its frame, advanced on the cart. Fig. 1 and FIG. 1-1 show a side view of a seat 1 of a motor vehicle disposed in the second row seat of a vehicle to seven

places réparties sur trois rangées. En pointillé, la feuillure 12 d'une porte est dessinée. Le siège 1 comporte une armature siège 2 avec un dossier 3 et une assise 4. L'assise 4 est rabattable, comme le montre Fig. 2. L'armature 2 est montée par son extrémité inférieure sur un rail mobile 7b d'un chariot intermédiaire 7. Ce chariot intermédiaire comporte ledit rail mobile 7b, qui peut coulisser sur un rail fixe 7a. Une butée de fin de course 8 limite le mouvement avant du rail fixe 7b. Le rail fixe 7a du chariot intermédiaire 7 est de son côté solidaire avec un rail mobile 6a qui glisse sur un rail fixe 6b de la glissière principale 6. Le rail fixe 7a du chariot intermédiaire 7 et le rail mobile 6a de la glissière principale 6 peuvent être monobloc, c'est-à-dire faits d'une seule pièce. Un renfort 10, qui va être décrit plus en détail ultérieurement, est articulé à l'extrémité avant du chariot intermédiaire 7. Le siège 1 est monté avec sa 15 glissière principale 6 sur le plancher 5. Fig. 2 montre le siège 1 avec son assise 4 rabattue contre le dossier 3. Ainsi le siège 1 est devenu, vu de côté, très étroit. Le but de la présente invention est de proposer un mécanisme permettant de pousser le siège avec son assise rabattue vers l'avant le plus possible 20 pour dégager au maximum l'espace devant la feuillure 12. Ainsi, comme on le voit sur Fig. 3, dans une deuxième démarche, le chariot intermédiaire est glissé sur la glissière principale 6 vers l'avant jusqu'à une position où il est arrêté par une butée 9. Dans cette position, le chariot intermédiaire 7 reste avec son rail fixe 7a engagé dans le rail fixe 25 de la glissière principale 6. L'articulation du renfort 10, à l'extrémité avant du chariot intermédiaire 7 permet au renfort 10 de se déplier vers le bas sous l'action d'un ressort (non représenté), qui le fait pivoter jusqu'à une position de support, définie par une butée de fin de course (non représentée sur les figures).places spread over three rows. Dotted, the rabbet 12 of a door is drawn. The seat 1 comprises a seat frame 2 with a backrest 3 and a seat 4. The seat 4 is foldable, as shown in FIG. 2. The armature 2 is mounted at its lower end on a movable rail 7b of an intermediate carriage 7. This intermediate carriage comprises said movable rail 7b, which can slide on a fixed rail 7a. A limit stop 8 limits the forward movement of the fixed rail 7b. The fixed rail 7a of the intermediate carriage 7 is on its side secured to a movable rail 6a which slides on a fixed rail 6b of the main slide 6. The fixed rail 7a of the intermediate carriage 7 and the movable rail 6a of the main slide 6 can to be monoblock, that is to say, made in one piece. A reinforcement 10, which will be described in more detail later, is articulated to the front end of the intermediate carriage 7. The seat 1 is mounted with its main slide 6 on the floor 5. FIG. 2 shows the seat 1 with its seat 4 folded against the backrest 3. Thus the seat 1 became, seen from the side, very narrow. The object of the present invention is to provide a mechanism for pushing the seat with its seat folded forward as much as possible to maximize the space in front of the rabbet 12. Thus, as seen in FIG. 3, in a second step, the intermediate carriage is slid on the main slide 6 forward to a position where it is stopped by a stop 9. In this position, the intermediate carriage 7 remains with its fixed rail 7a engaged in the fixed rail 25 of the main slide 6. The articulation of the reinforcement 10, at the front end of the intermediate carriage 7 allows the reinforcement 10 to unfold downwardly under the action of a spring (not shown), which rotates it to a support position, defined by an end stop (not shown in the figures).

30 L'articulation du renfort 10 est précontrainte par le ressort (non représenté) qui libère le renfort 10 dès que l'extrémité avant du chariot 7 dépasse le rail fixe de la glissière principale. A l'extrémité inférieure du renfort 10 est montée une roulette 11 pour 5 faciliter le déplacement du renfort 10 sur le plancher 5, normalement couvert d'une moquette. Ensuite, comme le montre Fig. 4, l'armature siège 2 qui est montée sur le rail mobile 7b du chariot intermédiaire 7 est poussée vers l'avant et le rail mobile 7b glisse sur le rail fixe 7a du chariot intermédiaire 7 jusqu'à la 10 butée 8 frontale du chariot intermédiaire 7. Ainsi, l'armature siège s'est approchée au maximum de la face arrière du dossier du siège avant du véhicule. L'espace devant la feuillure 12 de la porte latérale est dégagé au maximum et les sièges en troisième rangée du véhicule peuvent être accessibles dans 15 de bonnes conditions. Non seulement l'accès à la troisième rangée de sièges est rendu plus aisée, mais encore dans le cas où la troisième rangée de sièges est démontée ou repliée pour augmenter le volume du coffre de la voiture, ce dernier est davantage augmenté grâce à l'arrangement efficace des sièges de 20 deuxième rangée. The articulation of the reinforcement 10 is prestressed by the spring (not shown) which releases the reinforcement 10 as soon as the front end of the carriage 7 exceeds the fixed rail of the main slide. At the lower end of the reinforcement 10 is mounted a roller 11 to facilitate the movement of the reinforcement 10 on the floor 5, normally covered with a carpet. Then, as shown in Fig. 4, the seat armature 2 which is mounted on the movable rail 7b of the intermediate carriage 7 is pushed forward and the movable rail 7b slides on the fixed rail 7a of the intermediate carriage 7 to the 10 abutment 8 front of the carriage intermediate 7. Thus, the seat frame has approached the maximum of the rear face of the seat back of the vehicle. The space in front of the rebate 12 of the side door is maximally disengaged and the seats in the third row of the vehicle can be accessed in good conditions. Not only is access to the third row of seats made easier, but also if the third row of seats is dismantled or folded to increase the volume of the trunk of the car, the latter is further increased thanks to the effective arrangement of 20 second row seats.
