Description

1 L'invention concerne une matelassure de siège de véhicule automobile.The invention relates to a seat pad of a motor vehicle.

Il est connu, notamment du document EP-1 772 309, de réaliser une matelassure de siège de véhicule automobile comprenant une coiffe de revêtement, notamment à base de textile ou de cuir, et un bloc en mousse, notamment de polyuréthanne, ladite coiffe comprenant une zone centrale et une zone latérale, formant un bourrelet et étant destinée à être tournée vers l'extérieur du véhicule, ladite zone centrale étant surmoulée par ledit bloc et ladite zone latérale étant dissociée dudit bloc.  It is known, in particular from document EP-1 772 309, to produce a seat pad for a motor vehicle comprising a covering cap, in particular made of textile or leather, and a block made of foam, in particular polyurethane, said cap comprising a central zone and a lateral zone, forming a bead and being intended to be turned towards the outside of the vehicle, said central zone being overmolded by said block and said lateral zone being dissociated from said block.

Une telle réalisation, dans laquelle la coiffe n'est que partiellement surmoulée, permet de limiter la présence de plis sur la matelassure, dus à des dispersions dimensionnelles de coiffes.  Such an embodiment, in which the cap is only partially overmolded, makes it possible to limit the presence of folds on the padding, due to dimensional dispersions of caps.

Lors des entrées et sorties de passagers, la zone latérale, formant un bourrelet de maintien du passager assis, est sollicitée en flexion, notamment par les jambes du passager. Il en résulte une résistance limitée dans le temps, le bloc pouvant se fissurer superficiellement au niveau de l'interface entre les zones latérale et centrale.  At the entrances and exits of passengers, the lateral zone, forming a support bead of the seated passenger, is biased in bending, in particular by the passenger's legs. This results in limited resistance over time, the block being able to crack superficially at the interface between the lateral and central zones.

Une telle dégradation est principalement due au fait que la surface du bloc présente un frottement important avec l'envers de la zone latérale. Les mouvements de la zone latérale générés par les entrées et sorties du passager sont donc intégralement transmis au bloc et entraînent à la longue sa fissuration.  Such degradation is mainly due to the fact that the surface of the block has a significant friction with the back of the lateral zone. The movements of the lateral zone generated by the entrances and exits of the passenger are therefore integrally transmitted to the block and cause in the long run its cracking.

L'invention a pour but de pallier cet inconvénient.  The invention aims to overcome this disadvantage.

A cet effet, l'invention propose une matelassure de siège de véhicule automobile comprenant une coiffe de revêtement et un bloc à base de mousse, ladite coiffe comprenant une zone centrale et une zone latérale, formant un bourrelet, ladite zone centrale étant surmoulée par ladite mousse et ladite zone latérale étant dissociée dudit bloc, la surface dudit bloc disposée en regard de 2 ladite zone latérale étant pourvue d'une couche de glissement destinée à faciliter le glissement de ladite zone latérale contre ledit bloc.  For this purpose, the invention proposes a motor vehicle seat padding comprising a covering cap and a foam-based block, said cap comprising a central zone and a lateral zone, forming a bead, said central zone being overmolded by said foam and said lateral zone being dissociated from said block, the surface of said block disposed opposite said lateral zone being provided with a sliding layer intended to facilitate the sliding of said lateral zone against said block.

Dans cette description, les termes de positionnement dans l'espace (latéral,...) sont pris en référence à la matelassure disposée dans le véhicule.  In this description, the positioning terms in the space (lateral, ...) are taken with reference to the padding arranged in the vehicle.

Avec l'agencement proposé, la surface du bloc faisant face à la zone latérale est pourvue d'une couche de glissement permettant que les mouvements de la zone latérale générés par les entrées et sorties du passager ne soient pas intégralement transmis au bloc en entraînant sa fissuration.  With the proposed arrangement, the surface of the block facing the lateral area is provided with a sliding layer allowing the movements of the lateral zone generated by the entrances and exits of the passenger are not fully transmitted to the block by causing its cracking.

D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une représentation schématique partielle en coupe d'une matelassure selon une réalisation.  Other features and advantages of the invention will appear in the description which follows, with reference to the attached figure which is a partial schematic sectional representation of a padding according to one embodiment.

En référence aux figures, on décrit une matelassure 1 de siège de véhicule automobile comprenant une coiffe 2 de revêtement, notamment à base de textile ou de cuir 13, et un bloc 3 à base de mousse, notamment à base de polyuréthanne, ladite coiffe comprenant une zone centrale 4 et une zone latérale 5, formant un bourrelet, et étant destinée à être tournée vers l'extérieur du véhicule, ladite zone centrale étant surmoulée par ladite mousse et ladite zone latérale étant dissociée dudit bloc, la surface dudit bloc disposée en regard de ladite zone latérale étant pourvue d'une couche de glissement 6 destinée à faciliter le glissement de ladite zone latérale contre ledit bloc.  With reference to the figures, a padding 1 of a motor vehicle seat comprising a covering cap 2, in particular based on textile or leather 13, and a block 3 based on foam, in particular based on polyurethane, said cap comprising a central zone 4 and a lateral zone 5, forming a bead, and intended to be turned towards the outside of the vehicle, said central zone being overmolded by said foam and said lateral zone being dissociated from said block, the surface of said block disposed in view of said lateral zone being provided with a sliding layer 6 intended to facilitate the sliding of said lateral zone against said block.

Selon une réalisation, la couche de glissement 6 est surmoulée par la mousse du bloc 3.  In one embodiment, the sliding layer 6 is overmolded by the foam of the block 3.

Selon la réalisation représentée, la couche de glissement 6 est associée à la zone latérale 5 au niveau de la ligne frontière 7 entre ladite zone latérale et la zone centrale 4, notamment par couture 12, ce qui permet un bon 3 positionnement de ladite couche de glissement par rapport à ladite zone latérale.  According to the embodiment shown, the sliding layer 6 is associated with the lateral zone 5 at the border line 7 between said lateral zone and the central zone 4, in particular by seam 12, which allows a good positioning of said sliding relative to said lateral zone.

Selon la réalisation représentée, la couche de glissement 6 est à base de mousse 8 dont la face tournée vers la zone latérale 5 est associée, notamment par collage, à un matériau textile 9 de glissement, par exemple sous forme de non tissé ou de charmeuse.  According to the embodiment shown, the sliding layer 6 is based on foam 8 whose face facing the lateral zone 5 is associated, in particular by gluing, with a slip material 9, for example in the form of a nonwoven or a charmeuse .

Selon une variante non représentée, la couche de glissement 6 est sous forme d'un film de matière plastique, par exemple à base de polyuréthanne.  According to a variant not shown, the sliding layer 6 is in the form of a plastic film, for example based on polyurethane.

Selon la réalisation représentée, l'envers de la zone latérale 5 est formé d'une couche de mousse 10 dont la face tournée vers le bloc 3 est associée, notamment par collage, à un matériau textile de glissement 11, par exemple sous forme de non tissé ou de charmeuse.  According to the embodiment shown, the backside of the lateral zone 5 is formed of a layer of foam 10 whose face facing the block 3 is associated, in particular by gluing, with a sliding textile material 11, for example in the form of non-woven or charmeuse.

Une telle réalisation permet d'optimiser le glissement recherché.  Such an embodiment makes it possible to optimize the desired sliding.
