Description

GOUSSET DE RENFORT ENTRE PIED ARRIÈRE ET GOUTTIÈRE DE VOLET ARRIÈRE SUR CAISSE DE VÉHICULE AUTOMOBILEREINFORCEMENT GUSSET BETWEEN REAR PILLAR AND REAR SHUTTER GUTTER ON MOTOR VEHICLE BODY

L’invention a trait au domaine des véhicules automobiles, plus particulièrement des caisses ou structures de carrosserie de véhicules automobiles.The invention relates to the field of motor vehicles, more particularly bodies or bodywork structures of motor vehicles.

Une caisse ou structure de carrosserie de véhicule automobile comprend, classiquement, à chaque côté latéral, un pied avant ou A, un pied milieu ou B, et un pied arrière ou C. Par pied on entend un montant en forme de profilé creux greffé au longeron inférieur par une zone élargie à la manière d’un pied. Le pied milieu ou B et le pied arrière ou C délimitent une ouverture de porte latérale arrière pour les passagers arrière. Le pied arrière ou C s’étend vers le haut jusqu’au toit du véhicule automobile. Il délimite aussi l’avant d’un passage de roue arrière. Cette dernière est suspendue à la caisse du véhicule automobile via un ressort et un amortisseur, fixés à la caisse dans le passage de roue, c’est-à-dire à proximité immédiate du pied arrière ou C.A motor vehicle body or body structure conventionally comprises, on each lateral side, a front pillar or A, a middle pillar or B, and a rear pillar or C. By pillar is meant an upright in the form of a hollow profile grafted to the lower spar by an area widened like a foot. The middle pillar or B and the rear pillar or C define a rear side door opening for the rear passengers. The rear foot or C extends upward to the roof of the motor vehicle. It also delimits the front of a rear wheel arch. The latter is suspended from the body of the motor vehicle via a spring and a shock absorber, fixed to the body in the wheel arch, that is to say in the immediate vicinity of the rear foot or C.

De manière générale, les points d’appui de suspension sont des zones sujettes à déplacement dynamique lors du roulage du véhicule. Il est généralement désirable de rigidifier au maximum ces zones.In general, the suspension support points are areas subject to dynamic displacement when the vehicle is moving. It is generally desirable to stiffen these areas as much as possible.

Le document de brevet publié FR 2 962 967 A1 divulgue une structure de carrosserie de véhicule automobile, comprenant une assise de banquette arrière rehaussée et pourvue de renforts latéraux ménageant des passages pour les ceintures de sécurité vers leurs points d’ancrage inférieur. Ces renforts latéraux compensent la rehausse de l’assise due à l’implantation de batteries d’accumulateurs électriques de traction sous l’assise en question. Ils n’augmentent pas intrinsèquement la rigidité de la structure, en particulier des points d’ancrage de la suspension arrière.The published patent document FR 2 962 967 A1 discloses a motor vehicle body structure, comprising a raised rear bench seat and provided with side reinforcements providing passages for the seat belts towards their lower anchor points. These side reinforcements compensate for the raising of the seat due to the installation of electric storage batteries for traction under the seat in question. They do not inherently increase the rigidity of the structure, in particular of the rear suspension mounting points.

L’invention a pour objectif de pallier au moins un inconvénient de l’état de la technique susmentionné. Plus particulièrement, l’invention a pour objectif d’augmenter la rigidité de la structure de carrosserie d’un véhicule automobile, au niveau des points d’ancrage de la suspension arrière.The aim of the invention is to overcome at least one drawback of the aforementioned state of the art. More particularly, the aim of the invention is to increase the rigidity of the body structure of a motor vehicle, at the level of the anchor points of the rear suspension.

L’invention a pour objet une structure de carrosserie pour véhicule automobile, comprenant, à un ou chacun des deux côtés latéraux, une platine d’appui pour un dossier de banquette arrière ; une gouttière de volet arrière ; remarquable en ce que la structure de carrosserie comprend, en outre, au côté latéral ou à chacun des deux côtés latéraux, une platine de renfort s’étendant entre, et reliant, la platine d’appui et la gouttière de volet arrière.The subject of the invention is a body structure for a motor vehicle, comprising, on one or each of the two lateral sides, a support plate for a rear seat backrest; a tailgate gutter; remarkable in that the bodywork structure further comprises, on the lateral side or on each of the two lateral sides, a reinforcement plate extending between, and connecting, the support plate and the rear flap gutter.

Selon un mode avantageux de l’invention, la platine de renfort comprend un guide de ceinture de sécurité pour la banquette arrière.According to an advantageous embodiment of the invention, the reinforcement plate comprises a seat belt guide for the rear seat.

Selon un mode avantageux de l’invention, le guide de ceinture de sécurité comprend une fente formée dans la platine de renfort.According to an advantageous embodiment of the invention, the seat belt guide comprises a slot formed in the reinforcing plate.

Selon un mode avantageux de l’invention, la fente formée dans la platine de renfort présente, à une extrémité latérale intérieure, une ouverture latérale.According to an advantageous embodiment of the invention, the slot formed in the reinforcing plate has, at an inner lateral end, a lateral opening.

Selon un mode avantageux de l’invention, le guide de ceinture de sécurité est situé totalement sur une portion de la platine de renfort correspondant à un tiers supérieur de ladite platine de renfort.According to an advantageous embodiment of the invention, the seat belt guide is located entirely on a portion of the reinforcement plate corresponding to an upper third of said reinforcement plate.

Selon un mode avantageux de l’invention, la platine de renfort est reliée à une face inférieure de la gouttière.According to an advantageous mode of the invention, the reinforcement plate is connected to an underside of the gutter.

Selon un mode avantageux de l’invention, la structure de carrosserie comprend, en outre, au côté latéral ou à chacun des deux côtés latéraux, une doublure d’aile arrière, la platine de renfort étant reliée à ladite doublure d’aile arrière.According to an advantageous embodiment of the invention, the body structure further comprises, on the lateral side or on each of the two lateral sides, a rear wing liner, the reinforcing plate being connected to said rear wing liner.

Selon un mode avantageux de l’invention, la platine de renfort comprend un bord latéral extérieur fixé à la doublure d’aile intérieure et un bord supérieur fixé à une face inférieure de la gouttière de volet arrière.According to an advantageous embodiment of the invention, the reinforcement plate comprises an outer side edge fixed to the inner wing lining and an upper edge fixed to an underside of the rear flap gutter.

Selon un mode avantageux de l’invention, la platine de renfort est alignée avec la platine d’appui de dossier.According to an advantageous embodiment of the invention, the reinforcement plate is aligned with the backrest support plate.

Selon un mode avantageux de l’invention, la platine de renfort est un embouti avec au moins une nervure de rigidification.According to an advantageous embodiment of the invention, the reinforcing plate is a stamped with at least one stiffening rib.

Les mesures de l’invention sont avantageuses en ce qu’elles permettent de rigidifier de manière optimale la structure de carrosserie, en particulier de manière effective au niveau des points d’ancrage de la suspension arrière, et ce avec des moyens simples, économiques et pouvant assurer, en outre, une fonction de guidage de ceinture de sécurité.The measures of the invention are advantageous in that they make it possible to stiffen the bodywork structure in an optimal manner, in particular effectively at the level of the anchoring points of the rear suspension, and this with simple, economical and which can also ensure a safety belt guiding function.
