Description
L’invention concerne une matelassure de siège de véhicule automobile, un siège pourvu d’une telle matelassure et un procédé de réalisation d’une telle matelassure.The invention relates to a seat pad of a motor vehicle, a seat provided with such padding and a method of making such padding.
Il est connu de réaliser une matelassure de siège de véhicule automobile, ladite matelassure comprenant : • un bloc de rembourrage en mousse moulée élastiquement compressible, • une nappe de détection de présence d’un occupant, ladite nappe étant reliée à un câble électrique de manière à pouvoir être intégrée dans un système d’activation de moyens de sécurité - par exemple sous forme d’un airbag - ladite nappe étant logée dans ledit bloc et ledit câble saillant dudit bloc. L’intérêt de mettre en oeuvre une telle nappe de détection est d’opérer une inhibition du déploiement des moyens de sécurité lorsque la matelassure n’est pas occupée.It is known to produce a motor vehicle seat padding, said padding comprising: an elastically compressible molded foam padding pad; an occupant presence detection pad, said pad being connected to an electric cable; it can be integrated in an activation system of safety means - for example in the form of an airbag - said sheet being housed in said block and said cable protruding from said block. The advantage of implementing such a detection web is to operate an inhibition of the deployment of the security means when the padding is not occupied.
Une réalisation connue, notamment du document FR2854363-A1, prévoit la réalisation d’un logement pour la nappe qui soit réalisé par une lame chaude insérée dans le bloc de mousse une fois moulé.A known embodiment, in particular FR2854363-A1, provides for the realization of a housing for the sheet which is made by a hot blade inserted into the foam block once molded.
La nappe étant directement au contact de la mousse, elle présente une grande sensibilité de détection.The web being directly in contact with the foam, it has a high sensitivity of detection.
Cependant, une telle façon de faire conduit à une opération de reprise après moulage qui vient grever le coût de fabrication de la matelassure. L’invention a pour but de pallier cet inconvénient. A cet effet, et selon un premier aspect, l’invention propose une matelassure de siège de véhicule automobile, ladite matelassure comprenant : • un bloc de rembourrage en mousse moulée élastiquement compressible, • une nappe de détection de présence d’un occupant, ladite nappe étant reliée à un câble électrique de manière à pouvoir être intégrée dans un système d’activation de moyens de sécurité, ladite nappe étant logée dans ledit bloc et ledit câble saillant dudit bloc, ladite nappe étant disposée dans un sachet en film thermoplastique pourvu d’une ouverture, ledit sachet étant surmoulé par ledit bloc, ledit câble saillant dudit sachet par ladite ouverture.However, such a method leads to a resumption after molding operation that comes to burden the manufacturing cost of padding. The invention aims to overcome this disadvantage. For this purpose, and according to a first aspect, the invention proposes a seat pad for a motor vehicle seat, said padding comprising: an elastically compressible molded foam pad, an occupant presence detection pad, said pad web being connected to an electrical cable so as to be integrated in an activation system of safety means, said web being housed in said block and said cable protruding from said block, said web being arranged in a thermoplastic film bag provided with an opening, said bag being overmolded by said block, said cable protruding from said bag by said opening.
Avec l’agencement proposé, on s’affranchit de l’opération de reprise sus décrite connue de l’art antérieur.With the proposed arrangement, it overcomes the above described recovery operation known from the prior art.
En outre, le fait d’utiliser un sachet en film thermoplastique conduit, du fait de la grande souplesse d’un tel film, à un comportement de la nappe en détection similaire à celui qu’elle présente dans la réalisation selon l’art antérieur sus évoqué.In addition, the fact of using a thermoplastic film bag leads, because of the great flexibility of such a film, to a behavior of the web detection similar to that it has in the embodiment according to the prior art mentioned above.
Selon d’autres aspects, l’invention propose un siège pourvu d’une telle matelassure et un procédé de réalisation d’une telle matelassure. D’autres particularités et avantages de l’invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une vue schématique en coupe partielle d’une matelassure dans son moule en cours d’expansion de la mousse du bloc.According to other aspects, the invention proposes a seat provided with such a padding and a method of making such padding. Other features and advantages of the invention will appear in the description which follows, with reference to the attached figure which is a schematic partial sectional view of a padding in its mold during expansion of the block foam.
En référence aux figures, on décrit une matelassure 1 - notamment d’assise -de siège de véhicule automobile, ladite matelassure comprenant : • un bloc de rembourrage 2 en mousse moulée élastiquement compressible, notamment de polyuréthanne, • une nappe 3 de détection de présence d’un occupant, ladite nappe étant reliée à un câble électrique 4 de manière à pouvoir être intégrée dans un système d’activation de moyens de sécurité - notamment sous forme d’airbag -, ladite nappe étant logée dans ledit bloc et ledit câble saillant dudit bloc - notamment par l’arrière -, ladite nappe étant disposée dans un sachet 5 en film thermoplastique pourvu d’une ouverture 6, ledit sachet étant surmoulé par ledit bloc, ledit câble saillant dudit sachet par ladite ouverture.With reference to the figures, a padding 1 - in particular seat-seat of a motor vehicle, said padding comprising: • a cushioning pad 2 of elastically compressible molded foam, especially polyurethane, • a sheet 3 of presence detection of an occupant, said sheet being connected to an electric cable 4 so as to be integrated in an activation system of safety means - in particular in the form of an airbag -, said sheet being housed in said block and said projecting cable said block - in particular from the rear -, said sheet being placed in a thermoplastic film bag 5 provided with an opening 6, said bag being overmolded by said block, said cable projecting from said bag by said opening.
Selon une réalisation, le film présente une épaisseur comprise entre 30 et 100 microns.In one embodiment, the film has a thickness of between 30 and 100 microns.
Une épaisseur de film aussi fine permet à la nappe 3 de présenter une grande sensibilité de détection.Such a thin film thickness allows the web 3 to have a high detection sensitivity.
Selon une réalisation, notamment lorsque le bloc 2 est à base de polyuréthanne, le film est bicouche et comprend une couche interne en polyéthylène et une couche externe en polyuréthanne qui présente l’avantage de permettre une parfaite adhésion entre ledit bloc et le sachet 5.According to one embodiment, especially when the block 2 is based on polyurethane, the film is bilayer and comprises an inner layer of polyethylene and an outer layer of polyurethane which has the advantage of allowing perfect adhesion between said block and the bag 5.
Selon diverses réalisations, le sachet 5 est confectionné par couture, soudure ou collage.According to various embodiments, the bag 5 is made by sewing, welding or gluing.
Selon la réalisation représentée, la nappe 3 est disposée vers le fond du sachet - correspondant notamment à l’avant dudit sachet -, le câble 4 s’étendant en partie dans le reste dudit sachet avant d’en déboucher.According to the embodiment shown, the sheet 3 is disposed towards the bottom of the bag - corresponding in particular to the front of said bag -, the cable 4 extending in part in the remainder of said bag before unblocking.
Une telle réalisation permet d’éviter à la mousse du bloc 2 de s’introduire jusqu’à la nappe 3 lors du moulage dudit bloc.Such an embodiment makes it possible to prevent the foam of the block 2 from being introduced to the sheet 3 during the molding of said block.
On décrit à présent, de façon non représentée, un siège de véhicule automobile comprenant une armature et une telle matelassure 1, ladite matelassure étant fixée sur ladite armature.Now described, not shown, a motor vehicle seat comprising a frame and such padding 1, said padding being fixed on said armature.
On décrit enfin un procédé de réalisation d’une telle matelassure 1, ledit procédé comprenant les étapes suivantes : • prévoir un moule 7 définissant une cavité de moulage 8, • prévoir au moins une lame 9, montée par une de ses extrémités 10 dans ledit moule de manière à pouvoir adopter une position saillante dans ladite cavité, • insérer ladite lame dans un sachet 5 à base de film thermoplastique dans lequel est logée une nappe 3 de détection de présence, ladite nappe étant reliée à un câble électrique 4 saillant dudit sachet et de ladite cavité - ledit câble passant ici par un orifice 11 prévu dans ledit moule -, • injecter dans ladite cavité un mélange précurseur de mousse, ladite lame étant en position saillante, de manière à réaliser un bloc de rembourrage 2 surmoulant ledit sachet, • après expansion de ladite mousse, démouler ledit bloc obtenu en extrayant ladite lame dudit sachet.Finally, a method of producing such a padding 1 is described, said method comprising the following steps: • providing a mold 7 defining a molding cavity 8, • providing at least one blade 9, mounted by one of its ends 10 in said mold so as to be able to adopt a projecting position in said cavity, • insert said blade in a bag 5 based on thermoplastic film in which is housed a presence detection web 3, said web being connected to an electrical cable 4 protruding said bag and said cavity - said cable passing here through an orifice 11 provided in said mold -, • injecting into said cavity a foam precursor mixture, said blade being in projecting position, so as to produce a padding block 2 overmolding said bag, After expansion of said foam, demolding said block obtained by extracting said blade from said bag.
De façon non représentée, on peut prévoir que le mélange précurseur de mousse soit injecté dans une coiffe de revêtement disposée au préalable dans le moule 7, de manière à obtenir une matelassure 1 dont ladite coiffe est surmoulée par le bloc 2.Not shown, it can be provided that the foam precursor mixture is injected into a coating cap previously disposed in the mold 7, so as to obtain a padding 1 which said cap is overmolded by the block 2.
Selon la réalisation représentée, la lame 9 est montée dans le moule 7 de façon déplaçable entre sa position saillante et une position permettant un démoulage du bloc 2.According to the embodiment shown, the blade 9 is mounted in the mold 7 in a displaceable manner between its projecting position and a position allowing demolding of the block 2.
Selon la réalisation représentée, la lame 9 est montée amovible dans le moule 7 de manière à pouvoir passer de l’une à l’autre de ses positions.According to the embodiment shown, the blade 9 is removably mounted in the mold 7 so as to pass from one to the other of its positions.
Selon la réalisation représentée, une extrémité 10 de la lame 9 est insérée dans un logement 12 prévu dans le moule 7.According to the embodiment shown, an end 10 of the blade 9 is inserted into a housing 12 provided in the mold 7.
Selon une réalisation, l’extrémité 10 de la lame peut être maintenue en place par des moyens magnétiques non représentés.In one embodiment, the end 10 of the blade can be held in place by magnetic means not shown.
En variante non représentée, la lame 9 est montée en articulation dans le moule 7 de manière à pouvoir passer de l’une à l’autre de ses positions.In variant not shown, the blade 9 is hingedly mounted in the mold 7 so as to be able to move from one to the other of its positions.
