La présente invention concerne un siège de véhicule automobile, du type comportant un dossier ayant une armature de support, une matelassure recouvrant l'armature de support, ainsi qu'un dispositif de sécurité à sac gonflable comportant un boîtier ayant un orifice initialement clos de sortie du sac gonflable, lequel dispositif de sécurité à sac gonflable est implanté suivant un côté latéral du dossier. The present invention relates to a motor vehicle seat, of the type comprising a backrest having a support frame, a padding covering the support frame, as well as an airbag safety device comprising a housing having an initially closed outlet orifice the airbag, which airbag safety device is located along a lateral side of the backrest.
On connaît des sièges de véhicule automobile ayant un dossier comportant une armature métallique recouverte par une matelassure qui est ellemême enveloppée dans une coiffe en matériau souple tel qu'un tissu. De tels sièges de véhicules automobiles peuvent comporter un dispositif de sécurité à sac gonflable dans une disposition latérale par rapport au dossier. Motor vehicle seats are known having a backrest comprising a metal frame covered by a padding which is itself wrapped in a cover made of flexible material such as a fabric. Such motor vehicle seats may include an airbag safety device in a lateral arrangement relative to the backrest.
Les dispositifs de sécurité à sac gonflable ou airbags latéraux comportent un boîtier rigide fixé sur l'armature et ayant un orifice de sortie du sac gonflable suivant un côté latéral du dossier. Ce boîtier comporte un couvercle d'obturation qui se brise, lors du gonflement et de la sortie du sac gonflable, lors du déclenchement du dispositif de sécurité, en cas d'accident. The airbag or side airbag safety devices comprise a rigid casing fixed to the frame and having an airbag outlet orifice along a lateral side of the backrest. This box has a shutter cover which breaks, when inflated and when the airbag leaves, when the safety device is triggered, in the event of an accident.
Le dispositif de sécurité à sac gonflable est généralement implanté dans une région de la matelassure recouverte par la coiffe en matériau souple. Ainsi, la coiffe du dossier doit être traversée par le sac gonflable au moment de son gonflement et de sa sortie du boîtier. The airbag safety device is generally located in a region of the padding covered by the cap of flexible material. Thus, the cover of the folder must be crossed by the airbag at the time of its inflation and its exit from the housing.
A cet effet, il est connu de prévoir une ouverture dans la coiffe du siège laissant à découvert le couvercle du boîtier ou au moins la partie du couvercle qui se brise pour laisser le passage au sac gonflable. Le montage de la coiffe sur le dossier doit être réalisé de manière à conserver un aspect visuel satisfaisant du siège. Un tel montage est difficile puisque le raccordement de la coiffe en matériau souple au dispositif à sac gonflable est délicat. For this purpose, it is known to provide an opening in the cover of the seat leaving the cover of the housing uncovered or at least the part of the cover which breaks to allow passage to the airbag. The mounting of the cover on the backrest must be carried out so as to maintain a satisfactory visual appearance of the seat. Such an assembly is difficult since the connection of the cap of flexible material to the airbag device is delicate.
L'invention a pour but de proposer un siège de véhicule automobile pouvant être réalisé facilement. The object of the invention is to propose a motor vehicle seat which can be produced easily.
A cet effet, l'invention a pour objet un siège de véhicule automobile du type précité, caractérisé en ce qu'il comporte une coque de garnissage re- couvrant au moins partiellement la face arrière du dossier, laquelle coque de garnissage comporte au moins un flanc s'étendant au moins partiellement To this end, the subject of the invention is a motor vehicle seat of the aforementioned type, characterized in that it comprises a lining shell covering at least partially the rear face of the backrest, which lining shell comprises at least one sidewall extending at least partially

suivant un côté latéral du dossier au-dessus du dispositif de sécurité à sac gonflable, le flanc présentant une ouverture de passage du sac gonflable. along a lateral side of the backrest above the airbag safety device, the sidewall having an opening for passage of the airbag.
Suivant des modes particuliers de réalisation, le siège de véhicule comporte l'une ou plusieurs des caractéristiques suivantes : - le boîtier fait partiellement saillie au travers de l'ouverture de passage du sac gonflable ; - le boîtier et le flanc de la coque de garnissage comportent des profils complémentaires d'accrochage ; - les profils d'accrochage complémentaires comportent au moins un crochet ménagé sur la face interne du flanc et au moins une saillie ménagée sur le boîtier et adaptée pour être reçue dans le ou chaque crochet ; - le boîtier est enserré directement entre l'armature de support et le flanc de la coque de garnissage ; - le contour de l'ouverture recouvre le boîtier autour de l'orifice de sortie du sac gonflable ; et - le flanc est réalisé en matière plastique rigide. According to particular embodiments, the vehicle seat comprises one or more of the following characteristics: - the housing partially protrudes through the passage opening of the airbag; - The housing and the side of the lining shell have complementary attachment profiles; - The additional attachment profiles comprise at least one hook formed on the internal face of the sidewall and at least one projection provided on the housing and adapted to be received in the or each hook; - The housing is clamped directly between the support frame and the side of the lining shell; - the outline of the opening covers the housing around the outlet of the airbag; and - the sidewall is made of rigid plastic.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins, sur lesquels : - la figure 1 est une vue de côté d'un siège de véhicule automobile selon l'invention ; et - la figure 2 est une vue partielle en section transversale du dossier prise suivant la ligne tt-ti. The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the drawings, in which: - Figure 1 is a side view of a motor vehicle seat according to the invention; and - Figure 2 is a partial cross-sectional view of the file taken along the line tt-ti.
Le siège représenté sur la figure 1 est un siège de véhicule automobile comportant une assise 10 portée par un piétement 12 à une extrémité de laquelle est articulé un dossier 14 équipé d'un dispositif de sécurité à sac gonflable 16. The seat shown in FIG. 1 is a motor vehicle seat comprising a seat 10 carried by a base 12 at one end of which is articulated a backrest 14 equipped with an airbag safety device 16.
Le dispositif de sécurité 16 est disposé suivant un côté latéral du dossier, par exemple un bord latéral dirigé vers l'extérieur du véhicule automo- bile. Ainsi, le dispositif de sécurité à sac gonflable est disposé dans l'épaisseur du dossier 14 et apparaît suivant son flanc. The safety device 16 is arranged along a lateral side of the backrest, for example a lateral edge directed towards the outside of the motor vehicle. Thus, the airbag safety device is arranged in the thickness of the backrest 14 and appears along its side.
Comme illustré sur la figure 2, le dossier comporte une armature mé- tallique 18 formée d'un profilé de section générale en U. As illustrated in FIG. 2, the backrest comprises a metal frame 18 formed from a profile of general U-shaped section.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
L'armature 18 est garnie, suivant la face avant du dossier, d'une matelassure 20 formée par exemple de mousse. La matelassure 20 définit la surface d'appui du dos pour le passager assis dans le siège. The frame 18 is lined, along the front face of the backrest, with a padding 20 formed for example of foam. The padding 20 defines the back support surface for the passenger seated in the seat.
La matelassure 20 est recouverte au moins sur sa face visible par une coiffe 22 en un matériau souple tel qu'un tissu. La coiffe 22 enveloppe la matelassure du siège. The padding 20 is covered at least on its visible face by a cap 22 made of a flexible material such as a fabric. The cover 22 envelops the padding of the seat.
En outre, le siège comporte une coque 24 réalisée dans un matériau rigide telle qu'une matière plastique. La coque 24 est solidarisée à l'armature de support 18. La coque 24 s'étend suivant la surface arrière du dossier, c'est-à-dire la surface opposée à la surface d'appui du dos du passager. In addition, the seat has a shell 24 made of a rigid material such as a plastic. The shell 24 is secured to the support frame 18. The shell 24 extends along the rear surface of the backrest, that is to say the surface opposite the bearing surface of the passenger's back.
La coque 24 présente au moins un flanc 26 formant au moins partiellement le côté latéral du dossier sur lequel est installé le dispositif de sécurité 16 à sac gonflable. Le flanc 26 est venu de matière avec la surface de la coque formant la surface arrière du dossier. The shell 24 has at least one side 26 at least partially forming the lateral side of the backrest on which the safety device 16 with an airbag is installed. The sidewall 26 came integrally with the surface of the shell forming the rear surface of the backrest.
Le flanc 26 se prolonge vers l'avant du dossier au-delà de l'armature 18 et son bord libre 27 disposé généralement verticalement s'étend audessus de la matelassure 20 recouverte de la coiffe 22. The sidewall 26 extends towards the front of the backrest beyond the frame 18 and its free edge 27 generally arranged vertically extends above the padding 20 covered with the cover 22.
Le flanc 26 recouvre partiellement le dispositif de sécurité 16, celui-ci étant enserré directement entre le flanc 26 et l'armature de support 18. The sidewall 26 partially covers the safety device 16, the latter being clamped directly between the sidewall 26 and the support frame 18.
Le dispositif de sécurité 16 à sac gonflable comporte un boîtier 28 à l'intérieur duquel est reçu un sac gonflable 30 initialement replié ainsi qu'un générateur de gaz 32 permettant le déploiement du sac gonflable. The airbag safety device 16 comprises a housing 28 inside which is received an airbag 30 initially folded as well as a gas generator 32 allowing the deployment of the airbag.
Le boîtier 30 présente sur sa face tournée vers l'extérieur un orifice 34 de sortie du sac gonflable. Cet orifice est initialement clos par un couvercle frangible adapté pour se rompre afin de laisser passer le sac gonflable lors de son déploiement. The housing 30 has on its face turned towards the outside an orifice 34 for exiting the airbag. This orifice is initially closed by a frangible cover adapted to rupture in order to allow the airbag to pass during its deployment.
Le flanc 26 présente une ouverture 36 de passage du sac gonflable 30 au travers de laquelle le boîtier 28 du dispositif de sécurité fait partiellement saillie. Ainsi, l'orifice 34 de sortie du sac gonflable, initialement obturé, s'étend coaxialement et en avant de l'ouverture 36 ménagée dans le flanc de la coque de garnissage. The sidewall 26 has an opening 36 for the passage of the airbag 30 through which the housing 28 of the safety device projects partially. Thus, the opening 34 of the inflatable bag outlet, initially closed, extends coaxially and in front of the opening 36 formed in the side of the lining shell.
Afin d'assurer la retenue du dispositif à sac gonflable, le boîtier 28 et la coque 26 présentent des profils complémentaires d'accrochage. En parti- In order to ensure the retention of the airbag device, the housing 28 and the shell 26 have complementary attachment profiles. In part-
<Desc/Clms Page number 4><Desc / Clms Page number 4>
culier, et comme illustré sur la figure 2, ces profils d'accrochage comportent au moins un crochet 40 ménagé sur la face intérieure du flanc 26 en bordure de l'ouverture 36. Le ou chaque crochet 40 est avantageusement venu de matière avec la coque 24. Le boîtier 28 comporte, à sa périphérie, une saillie ou bretelle 42 adaptée pour être reçue dans le ou chaque crochet. culier, and as illustrated in FIG. 2, these attachment profiles comprise at least one hook 40 formed on the inner face of the sidewall 26 at the edge of the opening 36. The or each hook 40 is advantageously made integrally with the shell 24. The housing 28 comprises, at its periphery, a projection or strap 42 adapted to be received in the or each hook.
Dans le mode de réalisation représenté, la saillie 42 forme un bourrelet périphérique s'étendant sur tout le contour du boîtier 28. Le bourrelet 42 s'appuie contre la face intérieure du flanc 26 à la périphérie de l'ouverture 36 dans les régions du flanc 26 dépourvues de crochet 40. In the embodiment shown, the projection 42 forms a peripheral bead extending over the entire contour of the housing 28. The bead 42 bears against the inner face of the sidewall 26 at the periphery of the opening 36 in the regions of the sidewall 26 without hook 40.
Le flanc 26 prend ainsi appui sur le bourrelet 42 suivant toute la périphérie du boîtier 28 maintenant ainsi le boîtier enserré entre l'armature 18 et la coque 24. The sidewall 26 thus bears on the bead 42 along the entire periphery of the housing 28 thus maintaining the housing sandwiched between the frame 18 and the shell 24.
Dans ces conditions, le contour de l'ouverture 36 recouvre le boîtier 28 autour de l'orifice 34 de sortie du sac gonflable, réduisant ainsi la surface exposée du dispositif à sac gonflable et améliorant l'aspect visuel du siège. Under these conditions, the outline of the opening 36 covers the housing 28 around the airbag outlet orifice 34, thereby reducing the exposed surface of the airbag device and improving the visual appearance of the seat.
On comprend qu'avec un tel agencement, l'essentiel du boîtier du dispositif de sécurité est reçu à l'intérieur du dossier et que ce boîtier est recouvert par la coque 24 sauf dans la région de l'ouverture de passage du sac gonflable. Ainsi, le sac gonflable n'a pas à traverser la coiffe 22. Aucun raccordement délicat à exécuter n'existe entre la coiffe 22 et le dispositif de sécurité. It is understood that with such an arrangement, most of the housing of the safety device is received inside the file and that this housing is covered by the shell 24 except in the region of the opening for passage of the airbag. Thus, the airbag does not have to pass through the cover 22. No delicate connection to be made exists between the cover 22 and the safety device.
Le raccordement devant être exécuté entre le boîtier 22 et la coque 24 s'effectue facilement et proprement par simple disposition bord à bord du boîtier 28 et du contour de l'ouverture 36. En effet, le boîtier et la coque étant tous deux réalisés dans des matériaux relativement rigides, leur raccordement peut s'effectuer simplement tout en préservant un aspect visuel agréable. The connection to be made between the housing 22 and the shell 24 is easily and cleanly carried out by simple edge-to-edge arrangement of the housing 28 and of the outline of the opening 36. In fact, the housing and the shell both being produced relatively rigid materials, their connection can be done simply while preserving a pleasant visual appearance.
