Description

L'invention concerne un composant de garnissage d'un siège de véhicule automobile et un procédé de réalisation d'un tel composant. Il est connu de réaliser un composant de garnissage d'un siège de véhicule automobile, ledit composant comprenant : - un bloc de rembourrage en mousse élastiquement compressible, ledit bloc comprenant une face d'appui, une tranche périphérique et une face d'envers, - une coiffe de revêtement de ladite face d'appui et d'au moins une partie de ladite tranche, ladite coiffe étant surmoulée par ledit bloc, - une plaque rigide de recouvrement de ladite face d'envers, ladite plaque étant surmoulée par ledit bloc, - une sangle associée à ladite plaque par insertion d'au moins l'une de ses extrémités à travers un orifice prévu dans ladite plaque, ladite extrémité étant fixée à un élément d'ancrage rigide de taille supérieure à celle dudit orifice et plaqué contre la périphérie intérieure dudit orifice, de sorte que ledit organe soit ancré par ledit orifice. Un composant tel que décrit ci dessus est typiquement un élément central de dossier arrière rabattable depuis une position d'appui dos, où la plaque est cachée et sensiblement verticale, vers une position d'utilisation où la plaque est disposée horizontalement pour recevoir des objets. Dans le cas où l'on souhaite réaliser un composant dont le bloc de mousse surmoule la plaque et la coiffe, afin notamment d'assurer une robustesse optimale dudit composant, on injecte un mélange précurseur de mousse dans l'espace délimité par ladite plaque et ladite coiffe qui ont été au préalable disposés dans un moule.The invention relates to a lining component of a motor vehicle seat and a method of producing such a component. It is known to produce a lining component of a motor vehicle seat, said component comprising: an elastically compressible foam padding block, said block comprising a bearing face, a peripheral wafer and an upside-down face, a covering cap of said bearing face and at least a part of said wafer, said cap being overmolded by said block, a rigid plate for covering said backside face, said plate being overmolded by said block; a strap associated with said plate by insertion of at least one of its ends through an orifice provided in said plate, said end being fixed to a rigid anchoring element of size greater than that of said orifice and pressed against the inner periphery of said orifice, so that said member is anchored by said orifice. A component as described above is typically a central backrest element foldable from a backrest position, where the plate is hidden and substantially vertical, to a position of use where the plate is arranged horizontally to receive objects. In the case where it is desired to produce a component whose foam block overmoulds the plate and the cap, in particular to ensure optimum strength of said component, is injected a precursor mixture of foam in the space defined by said plate and said cap which have been previously arranged in a mold.

La présence d'un orifice de fixation de la bande élastique dans la plaque risque de conduire à une fuite de mousse à travers ledit orifice lors de son expansion, ceci du fait d'un placage insuffisant de l'élément d'ancrage rigide contre la périphérie intérieure de l'orifice, ladite mousse débordant sur la face visible de la plaque, ce qui est esthétiquement préjudiciable. Par ailleurs, l'élément d'ancrage doit présenter une rigidité suffisante pour assurer un bon ancrage. Il faut donc concilier pour l'élément d'ancrage deux propriétés antagonistes : - d'une part il doit présenter une rigidité suffisante pour assurer sa fonction d'ancrage, - d'autre part il doit présenter une souplesse suffisante pour se conformer au mieux à la périphérie intérieure de l'orifice pendant l'expansion de ladite mousse, afin d'éviter des fuites de mousse. L'invention a pour but de proposer un agencement permettant de répondre simultanément à ces exigences. A cet effet et selon un premier aspect, l'invention propose un composant de garnissage d'un siège de véhicule automobile, ledit composant comprenant : - un bloc de rembourrage en mousse élastiquement compressible, ledit bloc comprenant une face d'appui, une tranche périphérique et une face d'envers, - une coiffe de revêtement de ladite face d'appui et d'au moins une partie de ladite tranche, ladite coiffe étant surmoulée par ledit bloc, - une plaque rigide de recouvrement de ladite face d'envers, ladite plaque étant surmoulée par ledit bloc, - une sangle associée à ladite plaque par insertion d'au moins l'une de ses extrémités à travers un orifice prévu dans ladite plaque, ladite extrémité étant fixée à un élément d'ancrage de taille supérieure à celle dudit orifice et plaqué contre la périphérie intérieure dudit orifice, de sorte que ledit organe soit ancré par ledit orifice, ledit élément étant sous forme d'un flan de matériau souple, ledit flan comprenant au moins une couche poreuse, ledit élément étant surmoulé par ledit bloc et ladite mousse imprégnant ladite couche poreuse de manière à la rigidifier. Avec l'agencement proposé, l'élément d'ancrage conserve sa souplesse tant qu'il n'a pas été imprégné par la mousse ce qui lui permet de garantir l'étanchéité en périphérie de l'orifice pendant l'expansion de la mousse. Par ailleurs, l'élément d'ancrage se rigidifie en fin d'expansion de la mousse par imprégnation de la couche poreuse, ce qui permet d'assurer un ancrage très efficace de la sangle, et ceci d'autant plus que l'élément d'ancrage est surmoulé par la mousse. Selon un deuxième aspect, l'invention propose un procédé de réalisation d'un tel composant.The presence of an orifice for fixing the elastic band in the plate may lead to a foam leakage through said orifice during its expansion, this due to insufficient plating of the rigid anchoring element against the inner periphery of the orifice, said foam overflowing on the visible face of the plate, which is aesthetically detrimental. In addition, the anchoring element must have sufficient rigidity to ensure good anchoring. It is therefore necessary to reconcile the anchoring element two antagonistic properties: - on the one hand it must have sufficient rigidity to ensure its anchoring function, - on the other hand it must have sufficient flexibility to comply at best at the inner periphery of the orifice during expansion of said foam, to prevent foam leakage. The object of the invention is to propose an arrangement making it possible to meet these requirements simultaneously. For this purpose and according to a first aspect, the invention provides a lining component of a motor vehicle seat, said component comprising: - an elastically compressible foam padding block, said block comprising a bearing face, a slice peripheral and an upside-down face, - a covering cap of said bearing face and at least a portion of said wafer, said cap being overmolded by said block, - a rigid plate for covering said reverse face said plate being overmolded by said block, - a strap associated with said plate by insertion of at least one of its ends through an orifice provided in said plate, said end being fixed to an anchoring element of greater size to that of said orifice and pressed against the inner periphery of said orifice, so that said member is anchored by said orifice, said element being in the form of a blank of flexible material, said blank comprising at least one porous layer, said element being overmoulded by said block and said foam impregnating said porous layer so as to stiffen it. With the proposed arrangement, the anchoring element retains its flexibility as long as it has not been impregnated with the foam, which enables it to guarantee the tightness at the periphery of the orifice during the expansion of the foam. . Furthermore, the anchoring element is stiffened at the end of expansion of the foam by impregnation of the porous layer, which ensures a very effective anchoring of the strap, and all the more so that the element Anchor is overmolded by the foam. According to a second aspect, the invention proposes a method for producing such a component.

D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes, dans lesquelles : - la figure 1 est une représentation en perspective d'un composant selon une réalisation dans son environnement, ledit composant étant un accoudoir rabattable en configuration de réception d'objets sur sa plaque, - la figure 2 est une vue de détail du composant de la figure 1 selon un mode de réalisation.Other features and advantages of the invention will appear in the description which follows, with reference to the appended figures, in which: FIG. 1 is a perspective representation of a component according to an embodiment in its environment, said component being a foldable armrest in an object receiving configuration on its plate, - Figure 2 is a detailed view of the component of Figure 1 according to one embodiment.

En référence aux figures, on décrit un composant 1 de garnissage d'un siège de véhicule automobile, ledit composant comprenant : - un bloc 2 de rembourrage en mousse - notamment de polyuréthanne - élastiquement compressible, ledit bloc comprenant une face d'appui 3, une tranche 4 périphérique et une face d'envers 5, - une coiffe 6 de revêtement de ladite face d'appui et d'au moins une partie de ladite tranche, ladite coiffe étant surmoulée par ledit bloc, - une plaque 7 rigide de recouvrement de ladite face d'envers, ladite plaque étant surmoulée par ledit bloc, - une sangle 8 associée à ladite plaque par insertion d'au moins l'une de ses extrémités à travers un orifice 9 prévu dans ladite plaque, ladite extrémité étant fixée à un élément 10 d'ancrage de taille supérieure à celle dudit orifice et plaqué contre la périphérie intérieure dudit orifice, de sorte que ledit organe soit ancré par ledit orifice, ledit élément étant sous forme d'un flan de matériau souple, ledit flan comprenant au moins une couche poreuse 12, ledit élément étant surmoulé par ledit bloc et ladite mousse imprégnant ladite couche poreuse de manière à la rigidifier. Selon la réalisation représentée, la sangle 8 est associée à l'élément 10 d'ancrage par couture 11. Selon une réalisation, la couche poreuse 12 est à base de fibres, par exemple en étant sous la forme d'un tissu qui a l'avantage de présenter une bonne résistance à l'arrachement, notamment lorsque la sangle 8 est fixée par couture 11. En variantes, on peut prévoir d'utiliser par exemple un non tissé ou un feutre. De façon non représentée, la couche poreuse 12 peut être pourvue d'une sous couche à base de mousse élastiquement compressible, une telle sous couche 25 permettant de donner de la tenue à l'élément 10 pendant le laps de temps s'écoulant entre son montage contre l'orifice 9 et l'imprégnation par la mousse de ladite couche poreuse. Selon la réalisation représentée, le flan est replié en deux. 30 Le flan présente ainsi une meilleure tenue qu'un flan en simple épaisseur pendant le laps de temps s'écoulant entre son montage contre l'orifice 9 et l'imprégnation par la mousse de la couche poreuse 12. 20 De façon non représentée, la coiffe 6 peut être pourvue d'un profilé périphérique rapporté, notamment par couture, ledit profilé étant emboité dans une gorge de réception prévue en périphérie de la plaque 7.Referring to the figures, there is described a lining component 1 of a motor vehicle seat, said component comprising: a block 2 of foam padding, in particular of elastically compressible polyurethane, said block comprising a bearing surface 3, a peripheral wafer 4 and a back face 5, - a cover 6 for coating said support surface and at least a portion of said wafer, said cover being overmolded by said block, - a rigid cover plate 7 said backside face, said plate being overmolded by said block, - a strap 8 associated with said plate by insertion of at least one of its ends through an orifice 9 provided in said plate, said end being fixed to an anchoring element of greater size than that of said orifice and pressed against the inner periphery of said orifice, so that said member is anchored by said orifice, said element being in the form of a blank of flexible material, said blank comprising at least one porous layer 12, said element being overmolded by said block and said foam impregnating said porous layer so as to stiffen it. According to the embodiment shown, the strap 8 is associated with the seam anchoring element 11. In one embodiment, the porous layer 12 is based on fibers, for example being in the form of a fabric which has the advantage of having a good resistance to tearing, especially when the strap 8 is fixed by sewing 11. In variants, it can be provided to use for example a nonwoven or felt. In a manner not shown, the porous layer 12 may be provided with a sub-layer based on elastically compressible foam, such a sub-layer 25 making it possible to give resistance to the element 10 during the lapse of time flowing between its mounting against the orifice 9 and the impregnation by the foam of said porous layer. According to the embodiment shown, the blank is folded in half. The blank thus has a better hold than a single-thickness blank during the lapse of time between its mounting against the orifice 9 and the impregnation with the foam of the porous layer 12. the cap 6 may be provided with a peripheral profile attached, in particular by stitching, said profile being fitted into a receiving groove provided on the periphery of the plate 7.

Un tel agencement permet au bloc 2 d'être confiné dans un volume délimité par la coiffe 6 et la plaque 7. Selon la réalisation représentée en figure 1, qui représente un accoudoir rabattable faisant office de dossier en position relevée, la sangle 8 est une bande élastique de maintien d'objets posés sur la plaque 7, ladite sangle étant accrochée par ses extrémités sur une étendue de la face visible de ladite plaque, au moins une desdites extrémités étant fixée à un élément 10 d'ancrage surmoulé par le bloc 2.Such an arrangement allows the block 2 to be confined in a volume delimited by the cap 6 and the plate 7. According to the embodiment shown in FIG. 1, which represents a foldable armrest acting as a backrest in the raised position, the strap 8 is a elastic band for holding objects placed on the plate 7, said strap being hooked by its ends over an extent of the visible face of said plate, at least one of said ends being fixed to an anchoring element 10 molded by the block 2 .

Selon une variante non représentée, la sangle 8 est une poignée de saisie du composant 1, les extrémités de ladite sangle étant fixées à un élément 10 d'ancrage commun surmoulé par le bloc 2.According to a variant not shown, the strap 8 is a gripping handle of the component 1, the ends of said strap being fixed to a common anchoring element 10 overmoulded by the block 2.

Une telle poignée peut notamment être disposée sur un accoudoir rabattable du type de celui présenté en figure 1. On décrit à présent un procédé de réalisation d'un composant 1, ledit procédé comprenant les étapes suivantes : - prévoir une coiffe 6 de matériau de revêtement, - prévoir une sangle 8 fixée par au moins une de ses extrémités à un élément 10 d'ancrage, ledit élément étant sous forme d'un flan de matériau souple, ledit flan comprenant au moins une couche poreuse, - prévoir une plaque 7 rigide pourvue d'un orifice 9 de taille inférieure à celle dudit élément, - insérer ladite sangle dans ledit orifice et plaquer ledit élément contre la périphérie intérieure dudit orifice, - disposer ladite coiffe et ladite plaque dans un moule, de façon à définir un espace d'injection de mousse délimité par ladite plaque et ladite coiffe, ladite sangle étant disposée à l'extérieur dudit espace, - injecter un mélange précurseur de mousse élastiquement compressible dans ledit espace, de façon à réaliser un bloc 2 de mousse surmoulant ladite coiffe, ladite plaque et ledit élément d'ancrage, - après expansion de la mousse, démouler le composant 1 obtenu.Such a handle may in particular be arranged on a folding armrest of the type shown in FIG. 1. A method of producing a component 1 is now described, said method comprising the following steps: providing a cap 6 of coating material - providing a strap 8 fixed by at least one of its ends to an anchoring element 10, said element being in the form of a blank of flexible material, said blank comprising at least one porous layer, - providing a rigid plate 7 provided with an orifice 9 of a size smaller than that of said element, - inserting said strap into said orifice and pressing said element against the inner periphery of said orifice, - arranging said cap and said plate in a mold, so as to define a space of foam injection defined by said plate and said cap, said strap being disposed outside said space, injecting a precursor mixture of elastomer foam only compressible in said space, so as to produce a block 2 of foam overmolding said cap, said plate and said anchoring element, - after expansion of the foam, demold component 1 obtained.
