Description

Siège escamotable pour véhicule automobile Retractable seat for a motor vehicle
L'invention concerne un siège escamotable pour véhicule automobile, notamment un siège de troisième rang. On connaît de nombreux agencements de sièges escamotables destinés notamment au troisième rang d'un véhicule automobile.The invention relates to a retractable seat for a motor vehicle, including a third-row seat. Numerous retractable seat arrangements are known, particularly for the third row of a motor vehicle.
Selon le document FR 2 828 845 au nom de la Demanderesse, on connaît un siège comportant un dossier et une assise montés à rotation l'un sur l'autre autour d'un premier pivot transversal, ladite assise étant en outre montée à rotation sur un plancher autour d'un deuxième pivot transversal, le siège étant mobile entre une position déployée dans laquelle l'assise est sensiblement horizontale et prend appui sur le plancher et le dossier est sensiblement redressé par rapport à l'assise, et une position rangée dans laquelle le dossier est sensiblement couché horizontalement à environ 90° en arrière de sa position redressée, avec, contre lui, l'assise également couchée à environ 180° en arrière de sa position déployée, l'assise et le dossier en position rangée étant au moins en partie escamotés dans un décrochement du plancher.According to the document FR 2 828 845 in the name of the Applicant, there is known a seat comprising a folder and a seat rotatably mounted on one another around a first transverse pivot, said seat being further mounted to rotate on a floor around a second transverse pivot, the seat being movable between an extended position in which the seat is substantially horizontal and bears on the floor and the backrest is substantially raised relative to the seat, and a position stored in which the backrest is substantially lying horizontally at about 90 ° back from its upright position, with, against it, the seat also lying at about 180 ° back from its deployed position, the seat and the backrest in the stowed position being at less partially retracted in a recess of the floor.
Dans cette réalisation, l'assise est solidaire d'une plaque d'assise qui vient refermer la cavité formée par le décrochement, lorsque le siège est escamoté, et qui se plaque contre le plancher, sous l'assise et en dépassant de celle-ci quand celle-ci est en position déployée. Pour pouvoir faire tenir à la fois l'assise et le dossier dans la cavité du décrochement, il faut avoir un dossier particulièrement mince au moins en dehors de ses régions de bord pour que l'assise vienne s'y loger. Cela nuit au confort et à l'esthétique du siège déployé.In this embodiment, the seat is secured to a seat plate which closes the cavity formed by the recess, when the seat is retracted, and which is pressed against the floor, under the seat and protruding from the seat. when it is in the deployed position. To be able to hold both the seat and the backrest in the cavity of the recess, it is necessary to have a particularly thin file at least outside its edge regions for the seat to come to lodge there. This is detrimental to the comfort and aesthetics of the deployed seat.
L'invention vise à proposer un nouveau siège escamotable, du même type général que le siège connu, mais n'en présentant pas les inconvénients et permettant au contraire d'obtenir simultanément un siège confortable et esthétique en position déployée et un coffre également esthétique et d'apparence unie en position escamotée.The invention aims to provide a new retractable seat, the same general type as the known seat, but does not have the disadvantages and allowing instead to simultaneously obtain a comfortable seat and aesthetic in the deployed position and a trunk also aesthetic and appearance united in retracted position.
L'invention atteint son but grâce à un siège comportant un dossier et une assise, ladite assise ou le dossier étant monté à rotation sur un plancher autour d'un deuxième pivot transversal, le siège étant mobile entre une position déployée dans laquelle l'assise est sensiblement horizontale et prend appui sur le plancher et le dossier est sensiblement redressé par rapport à l'assise, et une position rangée dans laquelle le dossier est sensiblement couché horizontalement à environ 90° en arrière de sa position redressée, avec, contre lui, l'assise également couchée à environ 180° en arrière de sa position déployée, l'assise et le dossier en position rangée étant au moins en partie escamotés dans un décrochement du plancher, l'assise étant solidaire sur sa face inférieure d'un élément plan participant au recouvrement du décrochement lorsque le siège est en position rangée, ledit élément plan étant un tapis formé d'une première plaque rigide accolée à ladite face inférieure de l'assise et d'au moins une autre plaque rigide articulée à la première plaque, lesdites plaques venant, dans la position déployée du siège, se ranger sous l'assise, caractérisé en ce qu'en position rangée, l'assise n'est sensiblement pas contenue dans le volume formé par le décrochement et lesdites plaques viennent recouvrir le siège rangé dans le décrochement et au moins une région de plancher voisine dudit décrochement.The invention achieves its goal through a seat having a backrest and a seat, said seat or backrest being rotatably mounted on a floor around a second transverse pivot, the seat being movable between an extended position in which the seat is substantially horizontal and bears on the floor and the backrest is substantially upright relative to the seat, and a stowed position in which the backrest is substantially lying horizontally about 90 ° back from its upright position, with against it, the seat also recumbents about 180 ° back from its deployed position, the seat and the backrest in the stowed position being at least partly retracted into a recess of the floor, the seat being secured to its underside of an element plan participating in covering the recess when the seat is in the stowed position, said flat element being a mat formed of a first rigid plate accol e to said lower face of the seat and at least one other rigid plate hinged to the first plate, said plates coming, in the deployed position of the seat, to be stored under the seat, characterized in that in a stowed position , the seat is substantially not contained in the volume formed by the recess and said plates are covering the seat stored in the recess and at least one floor region adjacent said recess.
Avantageusement, le tapis est constitué de deux plaques rigides articulées de part et d'autre de ladite première plaque.Advantageously, the belt consists of two rigid plates hinged on either side of said first plate.
Avantageusement, le second pivot sert d'articulation au dossier du siège.Advantageously, the second pivot serves as articulation to the seat back.
Avantageusement, le second pivot sert d'articulation au dossier du siège, par l'intermédiaire d'au moins une bielle prolongeant l'extrémité inférieure du dossier. Avantageusement, le premier pivot d'articulation de l'assise par rapport au dossier est disposé sur ladite bielle.Advantageously, the second pivot serves as a hinge to the seat back, by means of at least one connecting rod extending the lower end of the file. Advantageously, the first articulation pivot of the seat relative to the backrest is disposed on said connecting rod.
Avantageusement, le second pivot est placé en hauteur sur le plancher de ladite région adjacente au décrochement. Très avantageusement, le second pivot est placé sur un support en porte-à-faux fixé au plancher ou au décrochement de manière à dégager sous l'assise un espace de rangement du tapis replié.Advantageously, the second pivot is placed in height on the floor of said region adjacent to the recess. Very advantageously, the second pivot is placed on a cantilever support fixed to the floor or recess so as to release under the seat storage space of the folded carpet.
De préférence, le second pivot est sensiblement au niveau d'un relief du plancher à l'avant du décrochement, destiné à supporter l'avant de l'assise en position déployée, ledit relief constituant avantageusement une barre anti- sous-marinage. Ce même relief sert également de support à la partie avant du tapis déplié lorsque le siège est en position rangée. Un second relief est prévu à l'arrière du décrochement pour servir de support à la partie arrière du tapis déplié lorsque le siège est en position rangée, ce second relief pouvant être constitué par le rebord arrière de carrosserie au niveau de l'ouverture de hayon.Preferably, the second pivot is substantially at a relief of the floor at the front of the recess, intended to support the front of the seat in the deployed position, said relief advantageously constituting an anti-submarining bar. This same relief also serves to support the front portion of the unfolded carpet when the seat is in the stowed position. A second relief is provided at the rear of the recess to serve as support for the rear portion of the unfolded carpet when the seat is in the stowed position, this second relief may be constituted by the rear flange of the body at the hatch opening .
Avantageusement, le siège comporte aussi un tapis auxiliaire destiné à couvrir le bas du dossier en position déployée, à l'arrière.Advantageously, the seat also includes an auxiliary mat for covering the bottom of the backrest in the deployed position, at the rear.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture d'un mode de réalisation de l'invention, en référence aux dessins annexés montrant les différentes étapes de déploiement d'un siège de l'invention et sur lesquels :Other characteristics and advantages of the invention will become apparent on reading an embodiment of the invention, with reference to the appended drawings showing the various stages of deployment of a seat of the invention and in which:
-la figure 1 est une vue schématique latérale d'un siège de l'invention en position rangée dans le coffre, les trois plaques du tapis le recouvrant. -la figure 2 est une vue analogue à la figure 1, après qu'on a commencé à replier une plaque du tapis.FIG 1 is a schematic side view of a seat of the invention in a stowed position in the trunk, the three plates of the carpet covering it. FIG. 2 is a view similar to FIG. 1, after the beginning of folding a plate of the carpet.
-la figure 3 est une vue analogue à la figure 2, après qu'on a totalement replié ladite plaque du tapis. -la figure 4 est une vue analogue à la figure 3, après qu'on a commencé à relever le dossier et l'assise du siège.FIG. 3 is a view similar to FIG. 2, after having completely folded said carpet plate. FIG 4 is a view similar to Figure 3, after we began to raise the backrest and seat cushion.
-la figure 5 est une vue analogue à la figure 4, après qu'on a baissé l'assise du siège. Les figures montrent la partie arrière de plancher d'un véhicule non représenté dans sa totalité, et comprenant essentiellement un plancher 1 formant à l'avant un relief 2 (bossage d'anti-sous-marinage) et à l'arrière un décrochement 3 destiné à loger au moins partiellement le siège 10 en position rangée. Le siège 10 comporte un dossier 11 dont la partie inférieure se prolonge vers l'avant par deux pattes latérales 12 servant de support à un premier pivot 13 sur lequel pivote l'assise 14 par rapport au dossier. Le pivot 13 est situé vers la partie supérieure de l'assise, près de l'arrière de l'assise 14 (en position déployée de la figure 5), et vers la partie avant du dossier 11, juste au-dessous du bord du dossier (toujours sur la figure 5).FIG 5 is a view similar to Figure 4, after we lowered the seat cushion. The figures show the rear floor of a vehicle not shown in its entirety, and essentially comprising a floor 1 forming a front 2 relief (anti-submarining boss) and rear a recess 3 intended to at least partially accommodate the seat 10 in the stowed position. The seat 10 has a backrest 11 whose lower part is extended forward by two lateral lugs 12 serving to support a first pivot 13 on which pivots the seat 14 relative to the backrest. The pivot 13 is located towards the upper part of the seat, near the rear of the seat 14 (in the extended position of FIG. 5), and toward the front part of the backrest 11, just below the edge of the seat. folder (still in Figure 5).
Les pattes 12 s'étendent jusqu'à former un second pivot horizontal 15 porté par un support 16 coudé s' appuyant sur le fond du décrochement 3 et venant en porte-à-faux au-dessus du plancher 2 mais sans empiéter sur celui- ci. A la partie inférieure de l'assise 14 (« inférieure » quand l'assise est en position déployée d'utilisation) est attachée une plaque centrale de tapis principal 20, entourée de deux plaques 21, 22 articulées à la plaque centrale 20 en 23, 24.The tabs 12 extend to form a second horizontal pivot 15 carried by a bracket 16 bent pressing on the bottom of the recess 3 and cantilever above the floor 2 but without encroaching on it. this. At the lower part of the seat 14 ("lower" when the seat is in the deployed position of use) is attached a central core plate 20, surrounded by two plates 21, 22 hinged to the central plate 20 in 23 , 24.
A l'arrière du dossier 11 est attaché la plaque supérieure 30 d'un tapis auxiliaire en deux plaques articulées 30, 31.At the back of the backrest 11 is attached the upper plate 30 of an auxiliary belt in two articulated plates 30, 31.
Dans sa position de rangement de la figure 1, le dossier 11 est entièrement contenu dans le volume formé par le décrochement 3 dont la profondeur est sensiblement celle du dossier 11. L'assise 14 est plaquée à l'envers contre le dossier 11, et l'épaisseur de l'assise 14 est voisine de celle de la bosse 2.In its storage position of Figure 1, the backrest 11 is entirely contained in the volume formed by the recess 3 whose depth is substantially that of the backrest 11. The seat 14 is plated to upside down against the backrest 11, and the thickness of the seat 14 is close to that of the boss 2.
Dans cette position, le tapis 20, 21, 22 est maintenu d'une part sur l'assise 14 du siège, et d'autre part sur la bosse 2 et sur un support 4 sensiblement de même hauteur prévu à cet effet à l'arrière du coffre. Le tapisIn this position, the belt 20, 21, 22 is held on the one hand on the seat 14 of the seat, and on the other hand on the hump 2 and on a support 4 of substantially the same height provided for this purpose to the back of the chest. The carpet
20, 21, 22 forme donc un tapis sensiblement plat au fond du coffre ou de l'arrière du véhicule.20, 21, 22 therefore forms a substantially flat carpet at the bottom of the trunk or the rear of the vehicle.
La figure 2 montre la première étape de déploiement du siège, consistant à relever la plaque arrière 21 du tapis en la faisant pivoter sur son articulation 23 avec la plaque centrale 20, de façon à la rabattre complètement contre la plaque centrale 20 comme montré dans la figure 3.FIG. 2 shows the first stage of deployment of the seat, of raising the rear plate 21 of the belt by pivoting it on its articulation 23 with the central plate 20, so as to fold it completely against the central plate 20 as shown in FIG. figure 3.
On peut alors, comme montré sur la figure 4, soulever le dossier 11 (et donc l'assise 14) du siège 10 en le faisant pivoter autour du second pivot 15 prévu en surplomb du plancher 1. Un système non représenté permet de bloquer le dossier 11 dans cette position. Ce faisant, cela rapproche globalement le tapis 20, 21, 22 vers l'avant et fait glisser un peu la plaque 22 vers l'avant sur la bosse 2. Par ailleurs la plaque supérieure 30 du tapis auxiliaire arrière suit le dossier 11 et vient se placer sensiblement verticalement derrière le bas du dossier 11, en cachant ce qui se trouve en dessous.It is then possible, as shown in FIG. 4, to raise the backrest 11 (and therefore the seat 14) of the seat 10 by pivoting it around the second pivot 15 provided above the floor 1. A system not shown can block the folder 11 in this position. In doing so, this brings the belt 20, 21, 22 generally towards the front and slides the plate 22 a little forwardly on the hump 2. Furthermore, the upper plate 30 of the rear auxiliary belt follows the file 11 and comes place substantially vertically behind the bottom of the backrest 11, hiding what is underneath.
L'étape suivante et finale est représentée sur la figure 5 : on abaisse l'assise 14 en la faisant pivoter sur le premier pivot 13, jusqu'à sa position de butée définie par la butée de l'arrière de l'assise 14 contre le bas du siège 11 et/ou par le fait que l'avant de l'assise vient contre la bosse 2. Ce faisant, la plaque 22 du tapis est emmenée vers l'arrière et vient se replier contre les deux autres plaques 20, 21 déjà repliées sous l'assise. Ce repliement intégral du tapis 20-22 est rendu possible par le fait que les supports 16 sont en porte-à- faux et n'entravent pas le recul du tapis, parce que leurs pieds sont situés suffisamment en arrière, au niveau du décrochement 3. Le rangement du siège 10 s'effectue en inversant les manœuvres qui viennent d'être expliquées.The next and final stage is shown in FIG. 5: the seat 14 is lowered by pivoting it on the first pivot 13, to its abutment position defined by the abutment of the rear of the seat 14 against the bottom of the seat 11 and / or in that the front of the seat comes against the hump 2. In doing so, the plate 22 of the carpet is led backwards and is folded against the other two plates 20, 21 already folded under the seat. This integral folding of the belt 20-22 is made possible by the fact that the supports 16 are cantilevered and do not hinder the recoil of the carpet, because their feet are located sufficiently behind, at the recess 3 . The storage of the seat 10 is done by reversing the maneuvers just explained.
Naturellement, il peut être prévu un tapis 20-22 pour chacun des sièges 10 de troisième rang (par exemple, deux sièges), dont la manœuvre est indépendante.Naturally, there may be provided a carpet 20-22 for each of the seats 10 of third rank (for example, two seats), the maneuver is independent.
Le logement dégagé dans le décrochement 3 quand un siège est relevé peut être utilisé comme espace de rangement supplémentaire.The housing cleared in the recess 3 when a seat is raised can be used as additional storage space.
On peut aussi utiliser l'espace 5 laissé entre le tapis 20-22 et le siège 10 rangé (cf. figure 1) pour y ranger un cache-bagage à enrouleur. It is also possible to use the space left between the carpet 20-22 and the tidy seat 10 (see FIG. 1) to store a luggage cover with a reel.
