Description
PLANCHER D'ASSISE EN TOLE POUR VEHICULE AUTOMOBILE COMPORTANT DEUX RENFORTS EN V. La présente invention concerne un plancher d'assise en tôle pour véhicule automobile comportant des renforts en tôle. Les planchers d'assise de ce type sont le plus souvent en tôle d'acier. Cependant, dans certains cas, ces planchers sont en tôle d'aluminium. L'invention concerne plus particulièrement le plancher d'assise de rang 2 qui est destiné à recevoir les sièges arrière du véhicule.The present invention relates to a sheet metal seat base for a motor vehicle comprising reinforcements made of sheet metal. Seating floors of this type are usually made of sheet steel. However, in some cases, these floors are made of aluminum sheet. The invention relates more particularly to the seat floor of rank 2 which is intended to receive the rear seats of the vehicle.
Ce plancher d'assise de rang 2 est situé entre le plancher arrière de charge ou de coffre et le plancher d'assise de rang 1 destiné à supporter les sièges avant. Les planchers d'assise de rang 2 connus comportent des renforts en tôle pour que le plancher puisse satisfaire aux tests de choc arrière effectués à une vitesse de 16 km/h sous un angle de 100 .This tier 2 seating floor is located between the load or trunk rear floor and the Tier 1 seating floor to support the front seats. Known tier 2 floorboards have sheet metal reinforcements so that the floor can meet rear impact tests at a speed of 16 km / h at an angle of 100.
Un plancher d'assise renforcé de ce type est représenté sur la figure 1. Sur cette figure 1, la référence 1 désigne le bord avant du plancher, la référence 2 le bord arrière, et les références 3 et 4 les deux bords latéraux du plancher. Les renforts comprennent deux renforts transversaux 5 et deux renforts longitudinaux 6 en tôle d'acier fixés au plancher par soudure. Les principaux inconvénients de ces renforts 5, 6 sont les suivants : - ils augmentent considérablement la masse du plancher et, - ils encombrent la surface du plancher. Le but de la présente invention est de remédier aux inconvénients ci-dessus.A reinforced base floor of this type is shown in FIG. 1. In this FIG. 1, the reference 1 designates the front edge of the floor, the reference 2 the rear edge, and the references 3 and 4 the two lateral edges of the floor. . The reinforcements comprise two transverse reinforcements 5 and two longitudinal reinforcements 6 of sheet steel fixed to the floor by welding. The main disadvantages of these reinforcements 5, 6 are as follows: they considerably increase the mass of the floor and they encumber the surface of the floor. The object of the present invention is to overcome the above disadvantages.
Ce but est atteint, selon l'invention, grâce à un plancher d'assise en tôle pour véhicule automobile comportant des renforts en tôle, caractérisé en ce que lesdits renforts comprennent deux renforts disposés selon un V. Les résultats des tests de choc arrière à 16 km/h ont montré que la fixation sur le plancher de deux renforts en V permettait de renforcer efficacement le 30 plancher. En outre, ces deux renforts en V permettent de réduire la masse totale du plancher par rapport à celui renforcé par des renforts transversaux et longitudinaux, représenté sur la figure 1.This object is achieved, according to the invention, thanks to a sheet metal seat for a motor vehicle comprising sheet metal reinforcements, characterized in that said reinforcements comprise two reinforcements arranged according to a V. The results of the rear impact tests to 16 km / h showed that the fixing on the floor of two V reinforcements could effectively strengthen the floor. In addition, these two V-shaped reinforcements reduce the total mass of the floor relative to that reinforced by transverse reinforcements and longitudinal, shown in Figure 1.
De plus, les deux renforts en V du plancher selon l'invention encombrent moins sa surface. Dans une version préférée de l'invention, le plancher d'assise comprend un bord avant, un bord arrière et deux bords latéraux, chacun des deux renforts s'étendant entre le bord avant et l'un des bords latéraux. De préférence également, les deux renforts forment un V évasé vers l'arrière. Cette disposition des renforts permet au plancher de satisfaire pleinement au test de choc arrière à 16 km/h. Dans un mode de réalisation particulièrement avantageux de l'invention, l'avant de chacun des deux renforts est situé près du milieu du bord avant du plancher et l'arrière de chacun des deux renforts est situé dans une zone d'un bord latéral du plancher comprise entre le milieu de ce bord latéral et l'arrière de celui-ci. Dans ce mode de réalisation, l'arrière des deux renforts est situé sensiblement dans le prolongement des deux longeronnets latéraux du plancher arrière de charge, ce qui permet de réduire la déformation du soubassement du véhicule en cas de choc arrière à 16 km/h. Selon d'autres particularités avantageuses de l'invention : - chacun des renforts est constitué par une plaque allongée en tôle comportant au moins une nervure longitudinale emboutie ; - les deux renforts sont soudés au plancher. Selon un autre aspect, l'invention concerne également un véhicule automobile équipé d'un plancher d'assise selon l'invention. De préférence, ledit plancher d'assise est un plancher d'assise de rang 2, c'est-à-dire destiné à recevoir les sièges arrière. De préférence également, les deux renforts sont soudés sur la face intérieure du plancher. D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après.In addition, the two V reinforcements of the floor according to the invention encumber less its surface. In a preferred version of the invention, the seat floor comprises a front edge, a rear edge and two lateral edges, each of the two reinforcements extending between the front edge and one of the lateral edges. Also preferably, the two reinforcements form a V flared backwards. This arrangement of reinforcements allows the floor to fully meet the rear impact test at 16 km / h. In a particularly advantageous embodiment of the invention, the front of each of the two reinforcements is located near the middle of the front edge of the floor and the rear of each of the two reinforcements is located in an area of a lateral edge of the floor between the middle of this side edge and the rear thereof. In this embodiment, the rear of the two reinforcements is located substantially in the extension of the two side rails of the load rear floor, which reduces the deformation of the vehicle underbody in case of rear impact at 16 km / h. According to other advantageous features of the invention: - each of the reinforcements is constituted by an elongate sheet metal plate having at least one longitudinal rib stamped; - the two reinforcements are welded to the floor. According to another aspect, the invention also relates to a motor vehicle equipped with a seat floor according to the invention. Preferably, said seat floor is a seat floor of rank 2, that is to say intended to receive the rear seats. Also preferably, the two reinforcements are welded to the inner face of the floor. Other features and advantages of the invention will become apparent throughout the description below.
Aux dessins annexés, donnés à titre d'exemples, non limitatifs : - la figure 2 est une vue en plan d'un plancher d'assise selon l'invention comportant deux renforts en V, - la figure 3 est une vue en plan montrant le plancher arrière de charge et le plancher d'assise selon l'invention ainsi que la barrière mobile utilisée lors d'un test de choc arrière à 16 km/h. La figure 2 représente un plancher d'assise en tôle pour véhicule automobile qui comporte des renforts en tôle 7 et 8. Ces renforts comprennent deux renforts 7 et 8 disposés selon un V. Ce plancher d'assise est un plancher d'assise de rang 2 et comprend un bord avant 9, un bord arrière 10 et deux bords latéraux 11, 12. Chacun des deux renforts 7, 8 s'étend entre le bord avant 9 et l'un des bords latéraux 11, 12. Comme montré sur la figure 2, les deux renforts 7, 8 forment un V évasé vers le bord arrière 10 et l'avant de chacun des deux renforts 7, 8 est situé près du milieu du bord avant 9 du plancher et l'arrière de chacun des deux renforts 7, 8 est situé dans une zone d'un bord latéral 11, 12 du plancher comprise entre le milieu de ce bord latéral 11, 12 et l'arrière de celui-ci. De plus, chacun des renforts 7, 8 est constitué par une plaque allongée en tôle d'acier ou d'aluminium comportant une ou plusieurs nervures longitudinales embouties 13, 14. Les deux renforts 7, 8 peuvent être soudés ou rivetés au plancher.In the accompanying drawings, given by way of non-limiting example: FIG. 2 is a plan view of a seat floor according to the invention comprising two V-shaped reinforcements, FIG. 3 is a plan view showing the rear load floor and the seat floor according to the invention and the movable barrier used in a rear impact test at 16 km / h. FIG. 2 shows a sheet metal seating surface for a motor vehicle which comprises sheet metal reinforcements 7 and 8. These reinforcements comprise two reinforcements 7 and 8 arranged in a V-shape. This floor is a row seat floor. 2 and comprises a front edge 9, a rear edge 10 and two side edges 11, 12. Each of the two reinforcements 7, 8 extends between the front edge 9 and one of the side edges 11, 12. As shown in FIG. 2, the two reinforcements 7, 8 form a V flared towards the rear edge 10 and the front of each of the two reinforcements 7, 8 is located near the middle of the front edge 9 of the floor and the back of each of the two reinforcements 7, 8 is located in an area of a lateral edge 11, 12 of the floor between the middle of this side edge 11, 12 and the rear thereof. In addition, each of the reinforcements 7, 8 is constituted by an elongate sheet steel or aluminum plate having one or more stamped longitudinal ribs 13, 14. The two reinforcements 7, 8 may be welded or riveted to the floor.
En outre, les deux renforts 7, 8 sont de préférence soudés ou rivetés sur la face intérieure du plancher. La figure 3 représente, à échelle réduite, un plancher d'assise de rang 2 identique à celui représenté sur la figure 2 qui s'étend entre deux longerons supérieurs 15, 16.In addition, the two reinforcements 7, 8 are preferably welded or riveted on the inner face of the floor. FIG. 3 represents, on a reduced scale, a seat floor of rank 2 identical to that shown in FIG. 2 which extends between two upper longitudinal members 15, 16.
A l'arrière de ce plancher d'assise est situé un plancher arrière de charge 17 qui s'étend entre deux longeronnets 18, 19. Ce plancher arrière de charge 17 peut être en tôle ou en matière composite. On voit sur cette figure 3 que l'arrière des deux renforts 7, 8 du plancher d'assise est situé dans le prolongement des longeronnets 18, 19.At the rear of this seat floor is a rear load floor 17 which extends between two longitudinal members 18, 19. This load rear floor 17 may be sheet metal or composite material. It can be seen in this FIG. 3 that the rear of the two reinforcements 7, 8 of the seat floor is located in the extension of the longitudinal members 18, 19.
Lors d'un test de choc arrière, on déplace à une vitesse égale à 16 km/h, une barrière 20 inclinée de 100 contre le coin arrièregauche du véhicule. La flèche F représentée sur la figure 3 symbolise la direction du choc. Ce choc est encaissé par le longeron net arrière gauche 19.In a rear-impact test, a barrier inclined 100 against the rear-left corner of the vehicle is moved at a speed equal to 16 km / h. The arrow F shown in Figure 3 symbolizes the direction of impact. This shock is cashed by the left rear net spar 19.
L'arrière du renfort 8 du plancher d'assise situé dans le prolongement du longeronnet 19 permet à l'ensemble de la structure de résister au choc arrière en limitant l'endommagement du plancher d'assise. Le choc arrière exercé dans le sens de la flèche F de la figure 3, compte- tenu de l'inclinaison de sa direction, tend à déformer en parallélogramme le rectangle délimité par les deux longeronnets 18, 19 et les longerons 15, 16. Les deux renforts en V 7, 8 permettent d'éviter une telle déformation. Le renfort constitué par deux éléments en V permet également de réduire la masse par rapport au cas des deux longerons transversaux et longitudinaux représentés sur la figure 1. De plus, les deux renforts en V permettent de réduire l'encombrement sur la surface du plancher.The rear of the reinforcement 8 of the seat floor located in the extension of the spar 19 allows the entire structure to resist the rear impact by limiting damage to the seat floor. The rear impact exerted in the direction of the arrow F of Figure 3, given the inclination of its direction, tends to deform in parallelogram the rectangle defined by the two longitudinal members 18, 19 and the longitudinal members 15, 16. The two V-shaped reinforcements 7, 8 make it possible to avoid such deformation. The reinforcement constituted by two V-shaped elements also makes it possible to reduce the mass with respect to the case of the two transverse and longitudinal longitudinal members shown in FIG. 1. In addition, the two V-shaped reinforcements make it possible to reduce the space requirement on the surface of the floor.
