Description

PROFILE DE RECEPTION D'UN SIEGE ET VEHICULE EQUIPE DE CE PROFILE.PROFILE OF RECEIVING A SEAT AND VEHICLE EQUIPPED WITH THIS PROFILE.
La présente invention concerne un système de fixation d'un siège notamment de véhicule automobile, sur un plancher d'un véhicule notamment d'un véhicule automobile.The present invention relates to a fastening system for a seat including a motor vehicle, on a floor of a vehicle including a motor vehicle.
De manière traditionnelle, l'arrimage d'un siège dans un véhicule se fait par deux glissières qui sont rapportées sur le plancher de véhicule. Ces glissières sont généralement orientées longitudinalement par rapport à la direction de déplacement du véhicule. Le siège présente, pour sa part, des coulisseaux qui lui permettent de s'engager dans les glissières et de se déplacer par rapport à ces dernières. Le siège est de plus équipé au niveau de son piètement de moyens de blocage qui peuvent verrouiller le siège dans plusieurs positions au gré des besoins d'un utilisateur.Traditionally, the stowage of a seat in a vehicle is by two rails that are reported on the vehicle floor. These slides are generally oriented longitudinally with respect to the direction of movement of the vehicle. The seat has, for its part, slides that allow it to engage in the slides and move relative to them. The seat is further equipped at its base with locking means that can lock the seat in several positions according to the needs of a user.
Dans un véhicule automobile, les sièges de rang 1 , c'est-à-dire les sièges qui se trouve en face des portes avant du véhicule sont, sauf rares exceptions, montés sur des glissières et sont donc longitudinalement réglables.In a motor vehicle, the seats of rank 1, that is to say the seats in front of the front doors of the vehicle are, with rare exceptions, mounted on slides and are therefore longitudinally adjustable.
Dans l'aménagement intérieur de véhicule type monospace, les sièges de rang 2 et de rang 3 peuvent également être montés sur des glissières. Par conséquent, dans la mesure où ce type de véhicule peut présenter jusqu'à 7 à 8 sièges, il est prévu de 7 à 8 ensembles de deux glissières parallèles qui sont fixées dans le plancher.In the interior of a minivan type vehicle, the seats of rank 2 and tier 3 can also be mounted on slides. Therefore, since this type of vehicle can have up to 7 to 8 seats, there are 7 to 8 sets of two parallel rails that are fixed in the floor.
En pratique, on constate des dispersions dimensionnelles dans les cotes des planchers de véhicule. Malgré le soin apporté aux opérations de fabrication de la caisse du véhicule à laquelle appartient le plancher et de pose des glissières, le cumul des tolérances produit des dispersions dimensionnelles qui peuvent être préjudiciables au bon fonctionnement du siège.In practice, there are dimensional dispersions in the dimensions of the vehicle floors. Despite the care taken in the manufacturing operations of the body of the vehicle to which the floor belongs and the laying of the slides, the accumulation of tolerances produces dimensional dispersions that may be detrimental to the proper functioning of the seat.
Or, il importe que le parallélisme des glissières sur lesquelles coulisse le siège soit respecté de manière extrêmement rigoureuse. Un défaut de parallélisme se traduit par des bruits parasites et/ou des blocages intempestifs des sièges au cours de leur déplacement sur les glissières.However, it is important that the parallelism of the slides on which slides the seat is respected in an extremely rigorous manner. A lack of parallelism results in noise and / or untimely blocking of the seats during their movement on the slides.
Cela se traduit par de l'inconfort et des désagréments pour l'utilisateur.This results in discomfort and inconvenience for the user.
Les dispersions dimensionnelles que l'on peut constater dans les zones de fixation des glissières peuvent générer des défauts de parallélisme des glissières dans les directions liées au véhicule, longitudinale X et transversale Y définissant le plan du plancher du véhicule mais également dans la direction verticale Z.The dimensional dispersions that can be seen in the fixing zones of the slides can generate parallelism defects of the slides in the directions related to the vehicle, longitudinal X and transverse Y defining the plane of the vehicle floor but also in the vertical direction Z.
Le document FR-A-2 835 790 montre une manière de gérer les défauts de parallélisme des glissières qui prévoit d'embarquer des organes de calage dans les coulisseaux.Document FR-A-2 835 790 shows a way of managing the parallelism defects of the slideways which provides for the insertion of wedging members into the slides.
Les organes de calage montrés par ce document permettent d'absorber les dispersions dimensionnelles de manière très efficace au prix toutefois d'une certaine complexité mécanique.The wedging members shown in this document make it possible to absorb the dimensional dispersions in a very efficient manner, but at the expense of a certain mechanical complexity.
Il apparaît donc que des améliorations sont souhaitables dans le domaine de la fixation d'un siège réglable longitudinalement sur un plancher d'un véhicule.It therefore appears that improvements are desirable in the field of fixing a longitudinally adjustable seat on a floor of a vehicle.
Un but de l'invention est de proposer un système de fixation d'un siège qui s'affranchisse des dispersions dimensionnelles de la surface qui assure la réception du siège. Un autre but d'invention est de proposer un véhicule dont la fixation des sièges s'affranchit des dispersions dimensionnelles de la surface de réception et dont l'espace intérieur soit optimisé.An object of the invention is to provide a system for fixing a seat that eliminates dimensional dispersions of the surface that ensures the reception of the seat. Another object of the invention is to propose a vehicle whose seat attachment eliminates dimensional dispersions of the receiving surface and whose interior space is optimized.
L'invention concerne donc un profilé de réception d'un siège comprenant deux organes de coulissement parallèles ; le profilé intègre deux glissières parallèles latérales présentant chacune deux ailes formant un U susceptibles d^accueillir respectivement les organes de glissement du siège, et en ce que, au moins, une face latérale d'un profilé présente une rainure en queue d'aronde susceptible de recevoir des organes de glissement d'un siège. L'invention propose d'assurer la réception d'un siège par un profilé unique qui intègre deux glissières. Ce profilé qui peut, par exemple, être réalisé par extrusion a comme caractéristique d'incorporer les deux glissières dans lesquels circulent les organes de coulissement du siège. Ainsi, la gestion du parallélisme des glissières qui est critique pour le bon fonctionnement des sièges est traitée au niveau d'un composant unique en l'occurrence un profilé. Les éventuelles dispersions dimensionnelles longitudinale, transversale ou verticale que l'on peut constater au niveau du plancher du véhicule, sont donc sans conséquence pour les sièges et leur coulissement. De plus, en disposant parallèlement deux profilés, des moyens de réception d'un siège disposés entre les profilés sont crées. Pour assurer la réception d'un siège, il peut être prévu que chacune des ailes d'une glissière soit surmontée d'une lèvre tournée vers l'intérieur de la glissière.The invention therefore relates to a seat receiving profile comprising two parallel sliding members; the profile incorporates two lateral parallel rails each having two wings forming a U likely to respectively accommodate the sliding members of the seat, and in that at least one side face of a profile has a groove dovetail susceptible to receive sliding members of a seat. The invention proposes to ensure the reception of a seat by a single profile that integrates two slides. This profile which can, for example, be made by extrusion has the characteristic of incorporating the two rails in which the sliding members of the seat. Thus, the management of the parallelism of the slides which is critical for the proper functioning of the seats is treated at the level of a single component in this case a profile. Any longitudinal, transverse or vertical dimensional dispersions that can be seen at the floor of the vehicle, are therefore of no consequence for the seats and their sliding. In addition, by arranging two profiles parallel, means for receiving a seat disposed between the profiles are created. To ensure the reception of a seat, it can be expected that each of the wings of a slide is surmounted by a lip facing the inside of the slide.
Dans une forme d'exécution de l'invention, Ia partie centrale du profilé comprend un caisson positionné entre les deux glissières. Cette disposition a pour objet d'augmenter l'inertie du profilé. On peut rappeler que, en cas d'une forte décélération consécutive à un accident du véhicule, une partie de l'énergie doit être encaissée par la liaison entre le siège et son support. Une disposition particulière peut prévoir que le caisson comprend cinq alvéoles longitudinales délimitées latéralement par les parois des glissières et centralement par quatre voiles de matière.In one embodiment of the invention, the central part of the profile comprises a box positioned between the two slides. This provision is intended to increase the inertia of the profile. It may be recalled that, in the event of a sharp deceleration following an accident of the vehicle, part of the energy must be cashed by the connection between the seat and its support. A particular arrangement may provide that the box comprises five longitudinal cells delimited laterally by the walls of the slides and centrally by four webs of material.
Il peut être prévu que, au moins l'une des glissières soit pourvue dans au moins l'une de ses ailes d'une pluralité de perçages répartis selon un pas régulier. Ces perçages peuvent accueillir des organes de verrouillage comme, par exemple, des tétons qui permettent de verrouiller le siège dans une position quelconque du choix de l'utilisateur.It can be provided that at least one of the slides is provided in at least one of its wings with a plurality of holes distributed at a regular pitch. These holes can accommodate locking members such as, for example, pins that allow to lock the seat in any position of the user's choice.
Selon un autre aspect, l'invention concerne également un véhicule possédant un plancher équipé de deux profilés tels que précédemment décrits pouvant chacun recevoir un siège.According to another aspect, the invention also relates to a vehicle having a floor equipped with two profiles as previously described, each of which can receive a seat.
De préférence, les profilés sont orientés l'un par rapport à l'autre, de telle sorte que les rainures en queue d'aronde se font face. Ainsi, les deux profilés disposés côte à côte peuvent recevoir chacun un siège qui est porté à moitié par chacune d'eux. Selon un aménagement avantageux du véhicule, une cuvette de rangement d'un siège est ménagée dans le plancher d'un véhicule entre les deux profilés.Preferably, the profiles are oriented relative to each other, so that the dovetail grooves face each other. Thus, the two sections arranged side by side can each receive a seat which is worn half by each of them. According to an advantageous arrangement of the vehicle, a seat storage cup is formed in the floor of a vehicle between the two sections.
Cette disposition s'avère très avantageuse dans la mesure où le siège central qui peut être escamoté dans la cuvette est retenu par deux rainures qui n'interfèrent pas avec cette cuvette.This arrangement is very advantageous insofar as the central seat that can be retracted into the bowl is retained by two grooves that do not interfere with this bowl.
Pour accroître la flexibilité du véhicule, au moins l'un des sièges possède une assise supportée par un piètement, l'assise pouvant se déplacer transversalement par rapport au piètement. Cette disposition s'avère extrêmement utile dans le cas d'un véhicule équipé de deux profilés encastrant une cuvette dans laquelle se range un siège central. Lorsque ce siège est rangé, les deux sièges supportés par les profilés peuvent se rapprocher transversalement l'une de l'autre pour occuper l'espace laissé par le siège central.To increase the flexibility of the vehicle, at least one of the seats has a seat supported by a base, the seat can move transversely to the base. This provision is extremely useful in the case of a vehicle equipped with two profiles embedded in a bowl in which stows a central seat. When this seat is stored, the two seats supported by the profiles can be move transversely towards each other to occupy the space left by the central seat.
De façon concrète, le siège peut comprendre un piètement inférieur comprenant deux coulisseaux parallèles susceptibles d'être engagés dans les deux glissières d'un profilé et un piètement supérieur supportant l'assise relié au piètement inférieur par au moins un rail orienté perpendiculairement par rapport aux coulisseaux sur lequel le piètement supérieur peut coulisser par rapport au piètement inférieur.Specifically, the seat may comprise a lower base comprising two parallel slides that can be engaged in the two rails of a profile and an upper base supporting the base connected to the lower base by at least one rail oriented perpendicular to the sliders on which the upper leg can slide relative to the lower leg.
Pour sa bonne compréhension, l'invention est décrite en référence au dessin schématique ci annexé représentant, à titre d'exemple non limitatif, une forme de réalisation d'un profilé de fixation d'un siège et d'un véhicule selon l'invention.For a good understanding, the invention is described with reference to the attached schematic drawing showing, by way of non-limiting example, an embodiment of a section for fixing a seat and a vehicle according to the invention. .
Figure 1 est une vue en coupe transversale d'un véhicule équipé de deux profilés de fixation de siège, Figure 2 est une vue de dessus de ce véhicule,Figure 1 is a cross-sectional view of a vehicle equipped with two seat attachment profiles, Figure 2 is a top view of this vehicle,
Figure 3 est une vue en perspective d'un profilé,Figure 3 is a perspective view of a profile,
Figure 4 montre en perspective un siège fixé sur un profilé,Figure 4 shows in perspective a seat fixed on a profile,
Figure 5 montre une configuration possible d'un véhicule.Figure 5 shows a possible configuration of a vehicle.
De manière générale, un véhicule qu'il soit un véhicule automobile, ferroviaire ou aérien, présente un plancher 2 sur lequel sont fixés un ou plusieurs sièges 3 permettant à des passagers de prendre place et de voyager dans ce véhicule.In general, a vehicle whether it is a motor vehicle, rail or air, has a floor 2 on which are fixed one or more seats 3 allowing passengers to sit and travel in this vehicle.
Dans l'exemple représenté sur le dessin, on peut voir que le plancher du véhicule qui, en l'occurrence est un véhicule automobile, est pourvu de deux profilés 4 qui sont fixés, par exemple, par boulonnage sur le plancher 2. Chacun de ces profilés 4 intègre deux glissières 5 latérales qui, dans l'exemple représenté, sont séparées par un caisson 6 central.In the example shown in the drawing, it can be seen that the floor of the vehicle which, in this case is a motor vehicle, is provided with two profiles 4 which are fixed, for example, by bolting on the floor 2. Each of these sections 4 incorporates two side rails 5 which, in the example shown, are separated by a central box 6.
Chacune des glissières 5 présente une section transversale à deux ailes 8 en forme générale de U. L'extrémité de chacune de ailes 8 est pourvue d'une lèvre 9 tournée vers l'intérieur de la glissière.Each of the slides 5 has a cross section with two wings 8 in the general shape of U. The end of each of wings 8 is provided with a lip 9 facing the inside of the slide.
De manière pratique, les profilés 4 peuvent être en aluminium extrudé. D'autres métaux peuvent bien entendu être envisagés pour réaliser ces profilés et il peut également être tout à fait concevable de les réaliser en matière composite. On note également que, dans chacune des ailes 8 des glissières 5, des perçages 10 sont prévus à un pas régulier. On peut également observer la présence d'un caisson 6 entre les deux glissières 5, ce caisson 6, dans l'exemple représenté possède cinq alvéoles ; il s'agit de trois alvéoles centrales qui sont séparées par quatre voiles de matière 1 1 et de deux alvéoles latérales qui viennent se raccorder à chacune des glissières 5.In practice, the profiles 4 can be extruded aluminum. Other metals can of course be considered to make these profiles and it can also be quite conceivable to make them composite material. It is also noted that in each of the wings 8 of the slides 5, bores 10 are provided at a regular pitch. We can also observe the presence of a box 6 between the two slides 5, this box 6, in the example shown has five cells; it consists of three central cells which are separated by four webs of material 1 1 and two lateral cells which are connected to each of the slides 5.
La figure 2 montre la manière avec laquelle les profilés peuvent être disposés par rapport à l'architecture générale du plancher du véhicule.Figure 2 shows how the profiles can be arranged with respect to the general architecture of the vehicle floor.
Dans le présent exemple, la fixation des sièges de rang 2 et de rang 3 du véhicule est assurée par deux glissières 5 parallèles qui sont orientées dans l'axe longitudinal du véhicule.In the present example, the fixing of the tier 2 and tier 3 seats of the vehicle is provided by two parallel rails 5 which are oriented in the longitudinal axis of the vehicle.
On note que les deux profilés 4 encadrent une cuvette 12 sensiblement parallélépipédique dans laquelle peut venir se ranger un siège 3 escamotable.It is noted that the two sections 4 frame a substantially parallelepipedal bowl 12 in which can be arranged a retractable seat 3.
Il est à noter que, sur leur face bordant la cuvette 12, les deux glissières 5 sont pourvues d'une rainure 14 en queue d'aronde qui peut servir de. moyen de guidage à un siège 3 central.It should be noted that, on their side bordering the bowl 12, the two rails 5 are provided with a groove 14 dovetail which can serve as. guiding means to a central seat 3.
La forme en queue d'aronde est illustrative de la fonction générale visant à assurer la réception et le guidage d'un organe de glissement d'un siège central. En ce qui concerne les sièges 3 qui vont venir se fixer sur chacun des deux profilés 4, ils peuvent être d'une structure classique. Ces sièges peuvent comprendre un piètement qui présente des organes de fixation sur l'un des profilés 4. Le piètement, de manière générale, intègre deux coulisseaux 16 dont la section est complémentaire de celle des deux glissières 5 présentes dans le profilé 4 ; ces deux glissières 5 sont par construction parallèles, quels que soient les défauts de planéité ou de dimension du plancher sur lequel repose le profilé 4.The dovetail shape is illustrative of the general function to ensure the reception and guidance of a sliding member of a central seat. Regarding the seats 3 which will come to be fixed on each of the two sections 4, they may be of a conventional structure. These seats may comprise a base which has fasteners on one of the profiles 4. The base, in general, incorporates two slides 16 whose section is complementary to that of the two rails 5 present in the section 4; these two slides 5 are by parallel construction, whatever the flatness or size defects of the floor on which the profile 4 rests.
On voit ainsi l'un des avantages tout à fait significatif de l'utilisation de profilé 4 monolithique intégrant deux glissières 5 ; ce type de profilé peut ainsi assurer un excellent parallélisme desdites glissières.One thus sees one of the quite significant advantages of the use of monolithic profile 4 incorporating two slides 5; this type of profile can thus ensure excellent parallelism of said slides.
Compte tenu de la maîtrise du parallélisme des glissières 5 à l'intérieur d'un profilé 4, il peut être envisagé de produire un profilé de grande longueur pour recevoir plusieurs sièges en tandem. Dans le cas d'un véhicule automobile, il peut ainsi être envisagé de placer deux glissières 5 qui s'étendent entre le rang 2 et le rang 3 du véhicule. Dans le cas d'un véhicule de transport en commun routier, ferroviaire ou aérien, des profilés 4 de beaucoup plus grande longueur peuvent être envisagés.Given the mastery of the parallelism of the slides 5 inside a profile 4, it can be envisaged to produce a profile of great length to receive several seats in tandem. In the case of a motor vehicle, it can thus be envisaged to place two slides 5 which extend between the row 2 and the rank 3 of the vehicle. In the case of a road, rail or air transport vehicle, sections 4 of much greater length can be envisaged.
Un autre avantage de l'invention est que, non seulement les profilés peuvent assurer la réception d'un ou de deux sièges placés en tandem, mais deux profilés 4 disposés parallèlement l'un à l'autre peuvent assurer la fixation d'un siège central qui, dans l'exemple représenté, peut être escamoté dans la cuvette présente au centre du véhicule.Another advantage of the invention is that, not only can the profiles ensure the reception of one or two seats placed in tandem, but two sections 4 arranged parallel to each other can ensure the attachment of a seat central which, in the example shown, can be retracted into the bowl in the center of the vehicle.
On voit ainsi apparaître une seconde fonction des profilés qui est, par leurs rainures 14 en queue d'aronde, d'assurer à eux deux la fixation d'un siège central. Cette disposition est tout à fait intéressante dans le cas d'un siège qui a vocation à être escamoté puisque les moyens de fixation de ce siège n'interfèrent pas avec la cuvette 1 2 et donc ne gênent pas l'escamotage du siège.This shows a second function of the profiles which is, by their grooves 14 dovetail, to ensure the two of them fixing a central seat. This provision is very interesting in the case of a seat which is intended to be retracted since the fastening means of this seat does not interfere with the bowl 1 2 and therefore do not interfere with the retraction of the seat.
On peut noter maintenant un second aspect de l'invention qui peut être mis en œuvre lorsque le siège central est escamoté ou lorsque aucun siège central n'est prévu dans le véhicule. Par siège central, on entend un siège qui vient prendre position entre chacun des profilés.It may be noted now a second aspect of the invention that can be implemented when the central seat is retracted or when no central seat is provided in the vehicle. By central seat is meant a seat that comes to take a position between each of the profiles.
Dans ce cas de figure, on constate qu'un espace relativement important est dégagé entre deux sièges 3 supportés respectivement par un profilé. La figure 5 illustre ce cas de figure avec un siège 3 central escamoté dans la cuvette.In this case, it is found that a relatively large space is cleared between two seats 3 supported respectively by a profile. Figure 5 illustrates this case with a central seat 3 retracted in the bowl.
Pour une utilisation plus rationnelle de l'espace intérieur du véhicule, il est alors prévu une disposition particulière des sièges supportés par chacun des profilés 4. II est envisagé, comme on peut le voir sur la figure 3 par exemple, que Ie piètement de ces sièges est scindé en un piètement inférieur 1 7 et en un piètement supérieur 1 8 ; le piètement inférieur 1 7 et le piètement supérieur 18 sont reliés entre eux par des moyens autorisant un déplacement du piètement supérieur 1 8 par rapport au piètement inférieur 1 7 dans une direction perpendiculaire à la direction des profilés 4.For a more rational use of the interior space of the vehicle, it is then provided a particular arrangement of the seats supported by each of the profiles 4. It is envisaged, as can be seen in Figure 3 for example, that the base of these seats is split into a lower leg 1 7 and an upper leg 1 8; the lower base 17 and the upper base 18 are interconnected by means allowing movement of the upper base 18 relative to the lower base 17 in a direction perpendicular to the direction of the profiles 4.
En d'autres termes, comme cela apparaît sur la figure 4, on voit que le piètement inférieur 1 7 est constitué par deux coulisseaux 1 6 venant s'engager dans chacune des glissières 5 d'un profilé 4. On remarque que chacun des coulisseaux 16 est équipé de moyens permettant de verrouiller longitudinalement le siège par rapport au profilé. Ces moyens peuvent, par exemple, prendre la forme de téton venant s'engager dans l'un des perçages prévus dans les ailes des glissières.In other words, as can be seen in FIG. 4, it can be seen that the lower leg 1 7 is constituted by two slides 1 6 coming into each of the slides 5 of a section 4. Note that each of the slides 16 is equipped with means for locking longitudinally the seat relative to the profile. These means may, for example, take the form of a stud coming into one of the holes provided in the wings of the slides.
Quant au piètement supérieur 1 8 qui reçoit l'assise et le mécanisme d'articulation d'un dossier, celui-ci est relié au piètement inférieur par deux rails 20 transversaux qui permettent donc un déplacement dans un sens transversal au véhicule de l'assise et du dossier du siège. Ainsi, il est possible de mettre à profit l'espace qui se trouve entre les deux profilés pour rapprocher transversalement l'un vers l'autre deux sièges qui se trouvent respectivement sur chaque profilé 4. Lorsque les sièges sont rapprochés, il est bien entendu impossible de déployer le siège qui est escamoté dans la cuvette.As for the upper leg 1 8 which receives the seat and the hinge mechanism of a backrest, it is connected to the lower leg by two transverse rails 20 which allow a movement in a direction transverse to the vehicle of the seat and the seat back. Thus, it is possible to take advantage of the space between the two sections to move two seats transversely towards one another on each profile 4. When the seats are close together, it is of course impossible to deploy the seat that is retracted into the bowl.
La disposition permettant de rapprocher transversalement deux sièges peut être mise à profit dans un véhicule ayant une configuration de 2 - 3 - 2 c'est-à-dire deux sièges de rang 1 , trois sièges de rang 2 et deux sièges de rang 3 dans laquelle la fixation des sièges de rang 2 et de rang 3 se fait exclusivement par deux profilés qui s'étendent sur toute la longueur de la partie arrière du véhicule.The provision for bringing two seats transversely can be put to use in a vehicle having a configuration of 2 - 3 - 2 that is to say two seats of rank 1, three seats of rank 2 and two seats of rank 3 in which the fixing of the seats of rank 2 and rank 3 is made exclusively by two sections which extend over the entire length of the rear part of the vehicle.
Dans ce cas de figure, on peut envisager d'avoir pour le rang 2 trois sièges, deux sièges latéraux supportés par chacun des profilés et un siège central supporté par chacun des profilés au niveau des rainures en queue d'aronde ; en ce qui concerne le rang 3, il est peut être prévu d'avoir des sièges du type précité, c'est-à-dire permettant un déplacement transversal qui, compte tenu des impératifs architecturaux notamment de passage de roues, doivent être rapprochés transversalement l'un de l'autre. Ainsi, un tel véhicule pourrait utiliser quatre sièges totalement interchangeables qui peuvent être utilisés comme sièges latéraux de rang 2 et sièges de rang 3, tout en ne prévoyant pour la fixation de ces sièges que deux profilés qui s'étendent sur le plancher du véhicule au niveau des rangs 2 et des rangs 3. On voit ainsi que l'invention propose en premier lieu un profilé permettant d'assurer la réception et fixation d'un siège dans lequel Ie parallélisme est totalement indépendant de la planéité et des éventuelles dispersions dimensionnelles du plancher sur lequel le profilé est fixé et en second lieu l'invention permet, de manière simple, d'assurer la fixation d'un siège central escamotable ou non escamotable. Bien entendu, l'invention n'est pas limitée aux formes de réalisation décrites ci-dessus à titre d'exemples non limitatifs, mais elle en embrasse au contraire toutes les formes de réalisation. In this case, it is conceivable to have for rank 2 three seats, two side seats supported by each of the profiles and a central seat supported by each of the profiles at the grooves dovetail; with regard to the rank 3, it may be provided to have seats of the aforementioned type, that is to say, allowing a transverse displacement which, taking into account the architectural requirements including wheel passage, must be brought transversely one of the other. Thus, such a vehicle could use four fully interchangeable seats that can be used as tier 2 side seats and tier 3 seats, while providing for the attachment of these seats only two profiles that extend on the floor of the vehicle at row level 2 and ranks 3. It can thus be seen that the invention proposes in the first place a profile for ensuring the reception and fixing of a seat in which the parallelism is totally independent of the flatness and possible dimensional dispersions of the floor on which the profile is fixed and secondly the invention allows a simple way to ensure the attachment of a central seat retractable or non-retractable. Of course, the invention is not limited to the embodiments described above by way of non-limiting examples, but it encompasses all the embodiments.
