Description
La présente invention est relative à des articles de confort, tels que des sièges pour véhicules de transport en commun et plus particulièrement pour avions, accoudoirs, appuis-tête, banquettes, bornes d'amortissement ou analogues, comportant des âmes de garnissage équipées de barrière anti-feu. The present invention relates to comfort articles, such as seats for public transport vehicles and more particularly for airplanes, armrests, headrests, benches, damping stations or the like, comprising lining cores equipped with barrier. anti fire.
Il est connu de pourvoir l'ossature des sièges de véhicules d'un garnissage amortisseur de chocs, dont la forme s'adapte à celle de l'ossature du siège et qui est constitué par des mousses comportant un revêtement externe en un tissu décoratif. It is known practice to provide the framework of vehicle seats with a shock-absorbing lining, the shape of which adapts to that of the framework of the seat and which is constituted by foams comprising an external covering in a decorative fabric.
Il est, en outre, désormais classique d'utiliser à cet effet des mousses de polyuréthane qui sont, parmi les polymères amortisseurs de chocs existant dans le commerce, probablement les meilleurs matériaux du point de vue des propriétés mécaniques et du prix de revient. It is, moreover, now conventional to use for this purpose polyurethane foams which are, among the shock absorbing polymers existing on the market, probably the best materials from the point of view of mechanical properties and cost price.
Toutefois, étant donné que, malheureusement, les mousses de polyuréthane sont très sensibles à la température (parce que leurs groupes uréthane subissent facilement la pyrolyse et leurs liaisons aliphatiques sont thermiquement oxydables, la décomposition de ces mousses commence déjà à partir d'environ 2500C), il est de pratique courante de protéger contre le feu un garnissage en mousse de polyuréthane à l'aide d'une barrière anti-feu constituée par une doublure ou housse ignifuge, donc résistant au feu, interposée entre le garnissage et le revêtement décoratif. However, since, unfortunately, polyurethane foams are very sensitive to temperature (because their urethane groups easily undergo pyrolysis and their aliphatic bonds are thermally oxidizable, the decomposition of these foams already starts from around 2500C) , it is common practice to protect against fire a polyurethane foam lining using a fire barrier constituted by a fire-retardant lining or cover, therefore fire-resistant, interposed between the lining and the decorative coating.
Il est aussi connu de rendre les silicones, dont la combustion ne donne pas de produits toxiques, parfaitement ignifugéesàl'aide de charges (additifs) de formulation également connue. It is also known to make silicones, the combustion of which does not give toxic products, perfectly fireproofed using fillers (additives) of also known formulation.
La présente invention s'est donné pour but de pourvoir à une barrière anti-feu à base de silicone ignifugée qui répond mieux aux nécessités de la pratique que les barrières anti-feu existant antérieurement et visant au même but, notamment en ce que - elle permet d'obtenir une protection contre la flamme sans
modification des articles de confort,ni de leur procédé de
fabrication, - le coût de cette barrière anti-feu est nettement inférieur
au coût des barrières anti-feu de l'Art antérieur, - elle permet de protéger les articles de confort déjà exis
tants et la réparation de barrières anti-feu défectueuses
ou dégradées.The object of the present invention is to provide a fire barrier based on flame retardant silicone which better meets the needs of the practice than the fire barriers existing previously and aiming at the same goal, in particular in that - it provides flame protection without
modification of comfort items, or their process
manufacturing, - the cost of this fire barrier is much lower
at the cost of the fire barriers of the prior art, - it makes it possible to protect the comfort items already existing
tants and repair of defective fire barriers
or degraded.
La présente invention a pour objet des articles de confort, tels que sièges, appuis-tête, accoudoirs , banquettes, bornes d'amortissement ou analogues, comportant une âme en une matière polymère inflammable (notamment constituée par une mousse en polyuréthane) et une barrière de protection contre le feu de ladite âme inflammable, caractérisée en ce que la barrière anti-feu comporte un tissu présentant un haut degré de résistance à la flamme enduit (rendu étanche),sur au moins une de ses faces, d'une dissolution d'un mélange élastomère/silicone ignifugé. The present invention relates to comfort articles, such as seats, headrests, armrests, benches, damping posts or the like, comprising a core made of a flammable polymeric material (in particular constituted by a polyurethane foam) and a barrier. of fire protection of said flammable core, characterized in that the fire barrier comprises a fabric having a high degree of flame resistance coated (rendered waterproof), on at least one of its faces, with a dissolution of '' a flame-retardant elastomer / silicone blend.
Selon un mode de réalisation préféré de la barrière anti-feu conforme à l'invention, le tissu présentant un haut degré de résistance à la flamme est constitué par un tissu de verre. According to a preferred embodiment of the fire barrier in accordance with the invention, the fabric having a high degree of flame resistance consists of a glass fabric.
Selon une disposition avantageuse de ce mode de réalisation, le tissu de verre est sous forme de toile. According to an advantageous arrangement of this embodiment, the glass fabric is in the form of a canvas.
Selon une variante préférée de cette disposition, le tissu de verre est sous forme de jersey. According to a preferred variant of this arrangement, the glass fabric is in the form of jersey.
Selon un autre mode de réalisation avantageux de la barrière anti-feu conforme à l'invention, le tissu présentant un haut degré de résistance à la flamme est constitué par un tissu de fibres préoxydées. According to another advantageous embodiment of the fire barrier in accordance with the invention, the fabric having a high degree of flame resistance consists of a fabric of preoxidized fibers.
Outre les dispositions qui précèdent, l'invention comprend encore d'autres dispositions, qui ressortiront de la description qui va suivre. In addition to the foregoing provisions, the invention also comprises other provisions, which will emerge from the description which follows.
L'invention sera mieux comprise à l'aide du complément de description qui va suivre, qui se réfère au dessin annexé dans lequel la figure unique représente un article de confort constitué par un coussin protégé par la barrière anti-feu selon l'invention. The invention will be better understood with the aid of the additional description which follows, which refers to the attached drawing in which the single figure represents a comfort item consisting of a cushion protected by the fire barrier according to the invention.
Le coussin 1 comporte une âme en polyuréthane 2 revêtue par une barrière anti-feu 3 . Cette barrière est réalisée,conformément à l'invention, à l'aide d'un tissu présentant un haut degré de résistance à la flamme dont au moins une de ses faces est enduite, à savoir rendue étanche, par une dissolution d'un mélange élastomère/silicone ignifugé. Ce tissu est, de préférence, constitué par un tissu de verre, notamment du type "STEVENS-GENIN T235" dont le poids est d'environ 90 grammes par m2. Après enduction et vulcanisation, le tissu de verre présente un poids d'environ 110 grammes par m2.Le tissu ainsi enduit et le coussin en mousse de polyuréthane sont conformes à la norme ATS 1000.
En ce qui concerne le procédé de fabrication, celui-ci consiste à - nettoyer la surface du coussin en polyuréthane pour
enlever les copeaux, les poussières, etc... à l'aide d'un
solvant à évaporation rapide ne faisant pas trop
gonfler le polyuréthane, notamment à l'aide d'alcool
éthylique, - découper le patron correspondant à la barrière anti-feu
dans le-tissu enduit comme indiqué plus haut, en ménageant
de légers recouvrements aux découpes pour assurer l'étan
chéité au collage, - enduire le tissu de colle, à la racle, et imprégner légère-
ment la surface du polyuréthane de colle, - mettre en contact la barrière anti-feu découpée et enduite
de colle sur le coussin de polyuréthane(également enduit
de colle),touten exerçant une légère pression.The cushion 1 has a polyurethane core 2 coated with a fire barrier 3. This barrier is produced, in accordance with the invention, using a fabric having a high degree of flame resistance with at least one of its faces being coated, namely made waterproof, by dissolving a mixture elastomer / flame retardant silicone. This fabric is preferably made up of a glass fabric, in particular of the "STEVENS-GENIN T235" type, the weight of which is approximately 90 grams per m2. After coating and vulcanization, the glass fabric has a weight of approximately 110 grams per m2. The fabric thus coated and the polyurethane foam cushion comply with the ATS 1000 standard.
Regarding the manufacturing process, this consists of - cleaning the surface of the polyurethane cushion to
remove shavings, dust, etc ... using a
fast evaporating solvent not doing too much
inflate the polyurethane, in particular using alcohol
ethylene, - cut the pattern corresponding to the fire barrier
in the coated fabric as indicated above, taking care
slight overlaps at the cutouts to ensure the etan
bonding, - coat the fabric with glue, with a doctor blade, and lightly impregnate -
the surface of the polyurethane glue, - bring the cut and coated fire barrier into contact
glue on the polyurethane cushion (also coated
glue), while exerting slight pressure.
Pour permettre au solvant de nettoyage de s'évaporer, il est nécessaire de procéder par étapes. To allow the cleaning solvent to evaporate, it is necessary to proceed in stages.
En ce qui concerne la colle utilisée pour obtenir une liaison intime entre la barrière anti-feu selon l'invention et le coussin en mousse de polyuréthane, celle-ci est de préférence constituée par une silicone réticulable à froid, diluée dans un solvant : bien entendu, il faut régler la viscosité pour faciliter l'enduction qui, de préférence,est effectuée sur les deux faces accolées . Ce tissu est avantageusement sous forme de toile ou, de préférence, sous forme de jersey. As regards the adhesive used to obtain an intimate connection between the fire barrier according to the invention and the polyurethane foam cushion, this is preferably constituted by a cold crosslinkable silicone, diluted in a solvent: well Of course, the viscosity must be adjusted to facilitate the coating which, preferably, is carried out on the two adjoining faces. This fabric is advantageously in the form of canvas or, preferably, in the form of jersey.
La présente invention permet donc de réaliser des barrières anti-feu qui sont très légères, tout en présentant un comportement au feu exceptionnel. The present invention therefore makes it possible to produce fire barriers which are very light, while exhibiting exceptional fire behavior.
Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de réalisation et d'application qui viennent d'être décrits de façon plus explicite ; elle en embrasse, au contraire, toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée, de la présente invention : en particulier, bien que l'utilisation du tissu de verre soit préférable dans le cadre de l'invention en instance, on peut également utiliser d'autres tissus présentant un haut degré de résistance à la flamme et, en particulier, un tissu de fibres préoxydées, notamment celui connu sous la marque de fabrique ZFIROTEX". As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the framework, or the scope, of the present invention: in particular, although the use of the fabric glass is preferable in the context of the present invention, it is also possible to use other fabrics having a high degree of flame resistance and, in particular, a fabric of preoxidized fibers, in particular that known under the trademark ZFIROTEX ".
En outre, bien que la liaison intime entre la barrière anti-feu et le coussin en mousse de polyuréthane soit préférable à la liaison lâche ou flottante, à savoir sans adhérisation mutuelle, rien ne s'oppose à l'adoption de cette deuxième solution. In addition, although the intimate connection between the fire barrier and the polyurethane foam cushion is preferable to the loose or floating connection, that is to say without mutual adhesion, there is nothing to prevent the adoption of this second solution.
De plus, il va de soi que la barrière anti-feu selon l'invention peut coopérer avec un revêtement décoratif choisi parmi ceux qui sont connus des techniciens en la matière et selon chaque cas d'espèce. In addition, it goes without saying that the fire barrier according to the invention can cooperate with a decorative coating chosen from those which are known to technicians in the field and according to each case.
