Description

L'invention concerne un siège destiné notamment, mais non exclusivement, à l'équipement de véhicules de transport en commun, par exemple d'autobus, ou même de locaux publics.The invention relates to a seat intended in particular, but not exclusively, for equipping public transport vehicles, for example buses, or even public premises.

On sait que les sièges faisant l'objet de ce type d'utilisation sont soumis à de rudes épreuves. En effet, en plus de l'usure résultant d'une utilisation intensive, sans ménagement, ces sièges subissent constamment toutes sortes d'actes de vandalisme.We know that the seats subject to this type of use are subjected to severe tests. Indeed, in addition to the wear and tear resulting from intensive use, without care, these seats are constantly subjected to all kinds of acts of vandalism.

En conséquence à l'heure actuelle on envisage d'équiper les véhicules ou les locaux les plus exposés à de tels actes, de sièges dans lesquels la résistance a bien souvent été accrue au détriment du confort.Consequently, at present, it is envisaged to equip the vehicles or the premises most exposed to such acts, with seats in which the resistance has very often been increased at the expense of comfort.

Il est clair que du point de vue de la résistance, l'idéal serait de réaliser des sièges totalement métalliques. Cette solution présente cependant un certain nombre d'inconvénients :

  • En règle générale, outre le confort, elle ne permet pas d'obtenir un bon compromis prix de revient/poids/aspect esthétique. Son confort est inexistant. De plus, elle présente des inconvénients dus à la haute conductibilité thermique du métal : Dans le cas où le siège a été exposé à une basse température, l'utilisateur en s'asseyant ressentira le froid. Par contre si le siège a été exposé au soleil il deviendra brûlant et ne pourra pas être utilisé.
It is clear that from the point of view of resistance, the ideal would be to produce completely metallic seats. However, this solution has a number of drawbacks:
  • In general, in addition to comfort, it does not make it possible to obtain a good compromise between cost price / weight / aesthetic appearance. Its comfort is nonexistent. In addition, it has drawbacks due to the high thermal conductivity of the metal: In the case where the seat has been exposed to a low temperature, the user when sitting will feel cold. On the other hand, if the seat has been exposed to the sun, it will become hot and cannot be used.

L'invention a donc pour but de supprimer tous ces inconvénients. Elle propose un siège d'aspect esthétique agréable, résistant aux actes de vandalisme avec cependant un minimum de confort et qui ne comprend pas les inconvénients dus aux propriétés thermiques du métal. Ce siège présente, par ailleurs, l'avantage d'être plus léger que les sièges totalement métalliques de sorte qu'il convient parfaitement aux véhicules de transport en commun tels que des autobus. Il présente en outre l'avantage d'une grande simplicité de fabrication et de montage de sorte que son prix de revient, une fois monté est relativement bas.The invention therefore aims to eliminate all these drawbacks. It offers a seat of pleasant aesthetic appearance, resistant to acts of vandalism with however a minimum of comfort and which does not understand the disadvantages due to the thermal properties of the metal. This seat has, moreover, the advantage of being lighter than completely metal seats so that it is perfectly suitable for public transport vehicles such as buses. It also has the advantage of great simplicity of manufacture and assembly so that its cost, once assembled, is relatively low.

D'une façon plus précise, le siège selon l'invention se compose de deux coquilles s'assemblant l'une à l'autre à savoir :

  • - une coquille en matière plastique compacte formant la superstructure de l'assise et du dossier du siège, cette coquille présentant au moins, au niveau de chacune des deux bordures latérales du dos, un rebord orienté vers le bas et muni d'une rainure rectiligne orientée vers l'intérieur,
  • - une coquille métallique, par exemple en tôle d'acier, dont la bordure périphérique épouse sensiblement les formes de la bordure périphérique de la coquille en matière plastique et qui présente, au niveau de chacune des bordures latérales. au moins un élément en saillie destiné à venir s'engager dans une rainure correspondante de la coquille en matière plastique, de manière à ce que l'assemblage des deux coquilles puisse s'effectuer par coulissement à la façon d'un tiroir.
More specifically, the seat according to the invention consists of two shells joining together, namely:
  • - A compact plastic shell forming the superstructure of the seat and the seat back, this shell having at least, at each of the two lateral edges of the back, a flange oriented downwards and provided with a rectilinear groove inward-facing,
  • - A metal shell, for example of sheet steel, the peripheral edge of which substantially matches the shapes of the peripheral edge of the plastic shell and which has, at each of the lateral edges. at least one projecting element intended to engage in a corresponding groove in the plastic shell, so that the assembly of the two shells can be carried out by sliding in the manner of a drawer.

Par ailleurs, la conformation des deux coquilles est telle qu'en position assemblée, elles viennent en appui l'une sur l'autre dans le plan médian vertical de symétrie du siège.Furthermore, the conformation of the two shells is such that in the assembled position, they come to bear one on the other in the vertical median plane of symmetry of the seat.

L'invention prévoit en outre des moyens de fixation, par exemple par vissage, pour solidariser les deux coquilles au niveau de l'assise ainsi que, dans la coquille métallique, des moyens permettant la fixation du siège sur un élément de support.The invention further provides fixing means, for example by screwing, to secure the two shells at the level of the seat as well as, in the metal shell, means allowing the seat to be fixed on a support element.

Selon une autre caractéristique de l'invention, le siège comprend en outre un élément pouvant comporter une poignée ou une main courante, ou même un appui tête, venant se fixer, par emmanchement, sur la bordure supérieure de la coquille en matière plastique.According to another characteristic of the invention, the seat further comprises an element which may include a handle or a handrail, or even a headrest, coming to be fixed, by fitting, on the upper edge of the plastic shell.

Il devient ainsi possible, en partant d'une coque en matière plastique standard, d'obtenir une pluralité de finitions qui peuvent servir à personnaliser le siège tout en s'intégrant à l'esthétique de l'ensemble.It thus becomes possible, starting from a standard plastic shell, to obtain a plurality of finishes which can be used to personalize the seat while integrating with the aesthetics of the whole.

Selon une autre caractéristique de l'invention, la bordure périphérique de la coquille métallique présente une forme concave de sorte qu'en position assemblée du siège, on obtient, à la périphérie, une structure tubulaire permettant d'augmenter la résistance mécanique du siège et permettant, grâce aux formes arrondies ainsi obtenues, d'augmenter considérablement la sécurité (élimination de toute saillie présentant une quelconque agressivité).According to another characteristic of the invention, the peripheral edge of the metal shell has a concave shape so that in the assembled position of the seat, there is obtained, at the periphery, a tubular structure making it possible to increase the mechanical strength of the seat and allowing, thanks to the rounded shapes thus obtained, to considerably increase safety (elimination of any projection showing any aggressiveness).

Un mode de réalisation de l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels :

  • Figures 19 and 20 show schematically, in longitudinal section (Figure 19) and in cross section (Figure 20) the seat support structure.

Comme précédemment mentionné, le siège représenté sur ces dessins est réalisé par assemblage de deux coquilles, à savoir :

  • - une coquille métallique 1, en tôle mince emboutie, qui constitue l'infrastructure du siège, et,
  • - une coquille en matière plastique rigide 2, obtenue par moulage, qui constitue la superstructure du siège et en particulier la partie sur laquelle l'usager vient s'asseoir et peut venir s'adosser.
As previously mentioned, the seat shown in these drawings is produced by assembling two shells, namely:
  • a metal shell 1, made of stamped thin sheet metal, which constitutes the infrastructure of the seat, and,
  • - A rigid plastic shell 2, obtained by molding, which constitutes the superstructure of the seat and in particular the part on which the user sits and can come to lean.

Dans l'exemple représenté, le siège est supporté par une structure 3 de type cantilever qui vient se fixer latéralement, par exemple sur une paroi verticale. Il est clair que ce type de support n'est pas limitatif et que l'on peut prévoir tout autre type de support sans sortir du cadre de l'invention.In the example shown, the seat is supported by a cantilever type structure 3 which is fixed laterally, for example on a vertical wall. It is clear that this type of support is not limiting and that any other type of support can be provided without departing from the scope of the invention.

Comme on peut le voir, en particulier, sur les figures 3 à 9 la coquille métallique 1 présente un profil (vue de côté représentée figure 3) comprenant une partie sensiblement horizontale 4 servant pour l'infrastructure de l'assise et une partie 5 légèrement inclinée vers la verticale servant d'infrastructure du dossier, ces deux parties étant raccordées par une partie cintrée 6 par exemple de 100° environ.As can be seen, in particular, in FIGS. 3 to 9, the metal shell 1 has a profile (side view represented in FIG. 3) comprising a substantially horizontal part 4 serving for the infrastructure of the seat and a part 5 slightly inclined towards the vertical serving as the backrest infrastructure, these two parts being connected by a curved part 6, for example of approximately 100 °.

La coupe de cette coquille dans le plan médian vertical de symétrie fait apparaître, au niveau de la bordure antérieure de la partie 4 correspondant à l'assise, une concavité 7 légèrement évasée s'ouvrant vers le haut et s'étendant transversalement le long de ladite bordure.The section of this shell in the vertical median plane of symmetry reveals, at the level of the anterior border of the part 4 corresponding to the seat, a slightly flared concavity 7 opening upwards and extending transversely along said border.

De même, au niveau de l'amorce de la partie cintrée 6, la partie correspondant à l'assise 4 comprend une nervuration transversale 8 de concavité orientée vers le haut servant à la fois à augmenter la rigidité transversale de la coquille 1 et à faciliter la fixation de la coquille en matière plastique 2 et de la structure support 3 (trous de passage de vis 9 figure 7).Similarly, at the beginning of the curved part 6, the part corresponding to the seat 4 comprises a transverse rib 8 of concavity oriented upwards serving both to increase the transverse rigidity of the shell 1 and to facilitate fixing the plastic shell 2 and the support structure 3 (screw passage holes 9 in FIG. 7).

La partie 5 correspondant à l'infrastructure du dossier comprend, en outre, au niveau de sa bordure supérieure, une concavité transversale (embouti 10) orientée vers l'avant du siège, et terminée vers le haut par une aile transversale en saillie 11.The part 5 corresponding to the backrest infrastructure further comprises, at its upper edge, a transverse concavity (stamped 10) oriented towards the front of the seat, and terminated upwards by a projecting transverse wing 11.

Par ailleurs, comme on peut le voir sur les figures 5 à 9, la coquille métallique 1 comprend le long de ses bordures latérales une concavité (ou un embouti 12, 13) sensiblement en forme de U sur laquelle viennent se raccorder les emboutis transversaux 7, 8.Furthermore, as can be seen in FIGS. 5 to 9, the metal shell 1 comprises along its lateral edges a concavity (or a deep-drawn 12, 13) substantially in the shape of a U on which the transversal deep-drawn 7 are connected. , 8.

Sur la bordure rectiligne de l'embouti 12 situé dans la partie 5 correspondant à l'infrastructure du dossier l'embouti 12 se trouve prolongé par une aile 14 en saillie venant se raccorder à l'aile transversale 11.On the rectilinear border of the stamped 12 located in the part 5 corresponding to the infrastructure of the file, the stamped 12 is extended by a projecting wing 14 coming to be connected to the transverse wing 11.

Avec référence à la figure 10 le profil de la coquille en matière plastique 2 dans le plan médian vertical de symétrie du siège correspond sensiblement au profil correspondant de la coquille métallique 1, à la différence près qu'au lieu des concavités 7 et 8 de la coquille métallique 1, elle comprend des protubérances 16, 17 munies d'inserts 18, 19 servant pour la fixation par vissage des deux coquilles 1, 2.With reference to FIG. 10, the profile of the plastic shell 2 in the vertical median plane of symmetry of the seat corresponds substantially to the corresponding profile of the metal shell 1, with the difference that instead of the concavities 7 and 8 of the metal shell 1, it includes protrusions 16, 17 provided with inserts 18, 19 used for fixing by screwing the two shells 1, 2.

D'une façon générale la coquille en matière plastique 2 est munie d'un rebord périphérique 20 relativement épais destiné à venir en recouvrement de l'arête périphérique du rebord de la coquille métallique 1.In general, the plastic shell 2 is provided with a relatively thick peripheral rim 20 intended to overlap the peripheral edge of the rim of the metal shell 1.

Ce rebord comprend plus particulièrement, au niveau de la bordure supérieure 21 de la partie destinée à servir de dossier, un tenon 22 et éventuellement une ou plusieurs chevilles 23 permettant l'assemblage par emmanchement d'un élément 24 pouvant par exemple comprendre une poignée ou une main courante 24' ou encore un accessoire de toute autre nature.This rim more particularly comprises, at the upper edge 21 of the part intended to serve as a backrest, a lug 22 and possibly one or more pins 23 allowing the assembly by fitting of an element 24 which may for example include a handle or a 24 'handrail or an accessory of any other kind.

Il comprend par ailleurs au niveau des deux bordures latérales et de la bordure supérieure de la coquille 2, dans la partie destinée à servir de dossier, deux rainures rectilignes respectives 25 dans lesquelles peuvent venir s'engager, par coulissement, les ailes 11 et 14 en saillie de la coquille métallique 1. Ces rainures 25 se trouvent mises en évidence sur les demi-coupes représentées figure 12, 13 et 14 qui se rapportent à la figure 11.It also comprises at the two lateral edges and the upper edge of the shell 2, in the part intended to serve as a backrest, two respective rectilinear grooves 25 in which the wings 11 and 14 can engage by sliding projecting from the metal shell 1. These grooves 25 are shown in the half-sections shown in FIG. 12, 13 and 14 which relate to FIG. 11.

Il apparaît donc clairement que le montage des deux coquilles s'obtient en engageant les extrémités supérieures des ailes 14 dans les extrémités inférieures des deux rainures 25 puis en faisant coulisser les deux coquilles 1, 2 l'une par rapport à l'autre.It therefore clearly appears that the mounting of the two shells is obtained by engaging the upper ends of the wings 14 in the lower ends of the two grooves 25 and then sliding the two shells 1, 2 relative to each other.

Au terme de ce coulissement, les profils des deux coquilles 1, 2 dans le plan médian vertical de symétrie viennent s'appliquer l'un contre l'autre en faisant ainsi office de butée de fin de course.At the end of this sliding, the profiles of the two shells 1, 2 in the vertical median plane of symmetry are applied one against the other, thus acting as a limit stop.

La fixation de l'ensemble s'obtient par vissage de vis 26 traversant les perçages 9 de la coquille métallique 1 et venant se visser dans les inserts 18 de la coquille en matière plastique 2.The assembly is obtained by screwing screws 26 passing through the holes 9 of the metal shell 1 and coming to be screwed into the inserts 18 of the plastic shell 2.

Il est clair que le siège ainsi réalisé pourrait se monter sur un piètement de type classique en utilisant les vis de fixation 26.It is clear that the seat thus produced could be mounted on a base of the conventional type using the fixing screws 26.

Toutefois dans les exemples représentés sur les figures 1 et 2, le siège est représenté monté sur une structure support 3 de type spécial convenant pour certains types de véhicules de transport en commun.However in the examples shown in Figures 1 and 2, the seat is shown mounted on a support structure 3 of a special type suitable for certain types of public transport vehicles.

Telle que représentée en détail sur les figures 19 et 20, cette structure support fait intervenir deux tubes de support coudés parallèles 27, 28 présentant :

  • - une partie horizontale 29 sur laquelle vient se fixer la coquille métallique 1 au moyen d'une plaque intermédiaire 30 spécialement conformée à cet effet, et
  • - une partie légèrement inclinée 31 par rapport à l'horizontale dont l'extrémité libre est solidarisée par exemple par soudage à une plaque de fixation 32 qui peut elle-même venir se visser sur une paroi verticale 37, par exemple sur une cloison.
As shown in detail in FIGS. 19 and 20, this support structure involves two parallel bent support tubes 27, 28 having:
  • a horizontal part 29 on which the metal shell 1 is fixed by means of an intermediate plate 30 specially shaped for this purpose, and
  • - a slightly inclined part 31 relative to the horizontal, the free end of which is secured for example by welding to a plate that of fixing 32 which can itself be screwed onto a vertical wall 37, for example on a partition.

Le siège se trouve donc disposé transversalement par rapport aux tubes de support 27, 28 et déporté (en porte à faux) par rapport à la plaque de fixation 32 (structure de type cantilever).The seat is therefore arranged transversely relative to the support tubes 27, 28 and offset (cantilevered) relative to the fixing plate 32 (cantilever type structure).

La rigidité de cette structure est renforcée grâce à une entretoise et contreventement 33 horizontale reliant une platine verticale 34 soudée à l'extrémité de la partie horizontale 29 des tubes de support 27, 28 à la plaque de fixation 32.The rigidity of this structure is reinforced by a horizontal brace and bracing 33 connecting a vertical plate 34 welded to the end of the horizontal part 29 of the support tubes 27, 28 to the fixing plate 32.

Cette platine 34 peut en outre servir, notamment dans le cas de l'équipement de véhicules de transport en commun, à la fixation d'une colonne verticale 35 comme représenté figures 1 et 2.This plate 34 can also be used, in particular in the case of the equipment of public transport vehicles, for fixing a vertical column 35 as shown in FIGS. 1 and 2.
