Abstract

L'invention vise à certifier un siège pour une campagne HIC qui, au vu de son design, présente des caractéristiques défavorables (cavité et rangement du dossier positionnés au-dessus de la tablette dorsale) en utilisant une pièce qui joue le rôle de déflecteur lorsque la tête du mannequin positionné sur le siège arrière vient impacter le dossier du siège de devant.The invention aims to certify a seat for an HIC campaign which, in view of its design, has unfavorable characteristics (cavity and storage of the backrest positioned above the back pad) using a piece which acts as a deflector when the head of the manikin positioned in the back seat impacts the back of the front seat.

Description

s configurations actuelles de dossier, la barre est droite, comme cela est montré par la flèche de la figure 1.s current folder configurations, the bar is right, as shown by the arrow in Figure 1.

[011] Les différentes caractéristiques ci-dessous pourront être utilisées seules ou en combinaison pour définir la protection de la barre selon l'invention.The different characteristics below can be used alone or in combination to define the protection of the bar according to the invention.

[012] L'invention vise à certifier un siège pour une campagne HIC qui, au vu de son design, présente des caractéristiques défavorables (cavité et rangement du dossier positionnés au-dessus de la tablette dorsale) en utilisant une pièce qui joue le rôle de déflecteur lorsque la tête du mannequin positionné sur le siège arrière vient impacter le dossier du siège de devant.The invention aims to certify a seat for an HIC campaign which, in view of its design, has unfavorable characteristics (cavity and storage of the file positioned above the back shelf) by using a part which plays the role deflector when the head of the mannequin positioned on the rear seat impacts the front seat backrest.

[013] Les objectifs de la barre selon l'invention sont les suivants:The objectives of the bar according to the invention are as follows:

- supprimer le « chin attrapment >> en réduisant fortement les efforts s’appliquant sur le cou du mannequin, et tout particulièrement le moment My (upper neck) de manière à ce qu’il reste inférieur au maximum acceptable de 135 N.m.- remove the "chin catch" by greatly reducing the forces applied to the dummy's neck, and in particular the My (upper neck) moment so that it remains below the maximum acceptable of 135 N.m.

- Atteindre un score HIC inférieur à la valeur de 1000 qui correspond au maximum imposé par la règlementation,- Achieve a HIC score below the value of 1000 which corresponds to the maximum imposed by the regulations,

- Conserver une inertie constante sur la majeure partie de la pièce afin d’optimiser une efficacité maximale sur une large zone d’impact,- Maintain constant inertia over most of the part in order to optimize maximum efficiency over a large impact area,

- Grâce à sa forme adaptée, éviter l’ouverture de la tablette indésirable lors du glissement de la tête du mannequin sur le dossier après l’impact primaire.- Thanks to its suitable shape, avoid opening the unwanted shelf when the mannequin's head slides over the backrest after the primary impact.

[014] L’ invention consiste en l’utilisation d’une barre de déflection:[014] The invention consists in the use of a deflection bar:

- suffisamment rigide pour éviter que la tête ne se coince dans le logement supérieur (entrée pochette littérature),- rigid enough to prevent the head from getting stuck in the upper housing (literature pocket entry),

- à géométrie optimisée pour que la tête puisse glisser vers le bas en évitant la tablette et son attache de verrouillage lors des tests de choc de tête.- with optimized geometry so that the head can slide down while avoiding the tablet and its locking clip during head impact tests.

[015] Les dimensions de la barre respectent l’enveloppe du siège.[015] The dimensions of the bar respect the envelope of the seat.

[016] La barre est située dans une zone amenity pocket, située entre îo l’écran et la tablette dorsale.The bar is located in an amenity pocket area, located between the screen and the back shelf.

[017] Il sera possible de laisser un accès à la fonction rangement téléphone + littérature dans sa partie supérieure, démontable, laissant un accès au nettoyage entre sa partie inférieure et le capot.It will be possible to leave access to the telephone + literature storage function in its upper part, which can be dismantled, leaving access to cleaning between its lower part and the cover.

[018] La barre présente une longueur, une largeur, et une épaisseur. La longueur de la barre est orientée transversalement par rapport à la direction d'allongement longitudinale du dossier. La largeur de la barre est orientée sensiblement suivant la direction d'allongement longitudinale du dossier.The bar has a length, a width, and a thickness. The length of the bar is oriented transversely to the direction of longitudinal extension of the backrest. The width of the bar is oriented substantially in the direction of longitudinal elongation of the backrest.

[019] La barre présente une portion intermédiaire incurvée s'étendant entre deux extrémités rectilignes de la barre.The bar has a curved intermediate portion extending between two straight ends of the bar.

[020] Autrement dit, la barre présente un décrochement par rapport à ses extrémités dans sa partie intermédiaire.In other words, the bar has a recess with respect to its ends in its intermediate part.

[021] La barre présente une portion intermédiaire de forme bombée. La forme bombée est dirigée vers le passager, c’est-à-dire du côté opposé au dossier du siège.[021] The bar has an intermediate portion of domed shape. The curved shape is directed towards the passenger, that is to say on the side opposite the seat back.

[022] Par rapport à un point de référence du dossier, au moins une partie de la surface externe de la barre tournée du côté opposé au dossier est située à une hauteur supérieure à celle d'une attache de fermeture de tablette. Ces hauteurs sont mesurées suivant une direction sensiblement perpendiculaire à un plan d'extension de la tablette.[022] With respect to a reference point of the backrest, at least part of the external surface of the bar turned on the side opposite the backrest is situated at a height greater than that of a shelf closing fastener. These heights are measured in a direction substantially perpendicular to a plane of extension of the tablet.

[023] Une surface externe de la barre présente une forme de rampe.[023] An external surface of the bar has the shape of a ramp.

[024] Par rapport à une direction verticale, la rampe est inclinée suivant 5 une direction sensiblement perpendiculaire au plan d'extension de la tablette.Relative to a vertical direction, the ramp is inclined in a direction substantially perpendicular to the plane of extension of the tablet.

[025] En vue de côté, une intersection entre la rampe et un plan vertical est situé du côté d'un bord supérieur de la barre.[025] In side view, an intersection between the ramp and a vertical plane is located on the side of an upper edge of the bar.

[026] La barre est cintrée.[026] The bar is curved.

[027] La barre présente une section quasi-constante en zone centrale.The bar has an almost constant section in the central zone.

îo [028] La barre présente une section sensiblement triangulaire à bord arrondi.îo [028] The bar has a substantially triangular section with rounded edge.

[029] La barre est réalisée dans un matériau rigide, de préférence dans un matériau métallique.[029] The bar is made of a rigid material, preferably a metallic material.

[030] La barre est par exemple réalisée en aluminium.The bar is for example made of aluminum.

Le décalage de la barre, lié à sa géométrie, évite que te menton ne raccroche au retour, et réduit te niyeau de force subi par te passage pendant te choc.The offset of the bar, linked to its geometry, prevents your chin from hanging up on the return, and reduces the level of force undergone by your passage during your shock.
