Description
Structure pour siège de véhicule.Structure for vehicle seat.
La présente invention est relative aux structures pour sièges de véhicules. The present invention relates to structures for vehicle seats.
Plus particulièrement, l'invention concerne une structure pour siège de véhicule comportant une coque rigide en forme de caisson creux. More particularly, the invention relates to a structure for a vehicle seat comprising a rigid shell in the form of a hollow box.
Les structures connues de ce type sont réalisées par assemblage de deux plaques rigides distinctes, ce qui présente les inconvénients suivants :
-les deux plaques rigides doivent tre fabriquées séparément sur des chaînes de fabrication différentes, ce qui renchérit le processus de fabrication de la structure de siège,
-et les deux plaques rigides doivent ensuite tre positionnées de façon précise l'une par rapport à l'autre lors de leur assemblage, ce qui renchérit encore et rend délicat le processus de fabrication de la structure de siège.Known structures of this type are produced by assembling two separate rigid plates, which has the following drawbacks:
the two rigid plates must be manufactured separately on different production lines, which increases the manufacturing process of the seat structure,
and the two rigid plates must then be positioned precisely with respect to one another during their assembly, which further increases the cost and makes the manufacturing process of the seat structure difficult.
La présente invention a notamment pour but de pallier ces inconvénients. The present invention aims in particular to overcome these drawbacks.
A cet effet, selon l'invention, une structure de siège du genre en question est essentiellement caractéri- sée en ce que la coque en forme de caisson est constituée par une seule plaque rigide qui est repliée sur elle-mme selon une ligne de pliage en formant des premier et deuxième volets parallèles rabattus l'un contre l'autre en correspondance mutuelle, au moins le premier volet présen- tant des reliefs qui définissent la forme de caisson de la coque. To this end, according to the invention, a seat structure of the kind in question is essentially characterized in that the box-shaped shell is constituted by a single rigid plate which is folded back on itself along a fold line. by forming first and second parallel flaps folded against each other in mutual correspondence, at least the first flap having reliefs which define the shape of the hull box.
Grâce à ces dispositions, la structure en forme de coque est réalisée en une seule pièce selon un processus de fabrication simplifié, en utilisant une seule chaîne de fabrication pour l'ensemble de la structure. Thanks to these provisions, the shell-shaped structure is made in one piece according to a simplified manufacturing process, using a single production line for the entire structure.
De plus, comme les deux volets formant la structure en forme de coque sont reliés l'un à l'autre par une ligne de pliage, le positionnement relatifs de ces deux volets ne pose pas de difficulté. In addition, since the two flaps forming the shell-shaped structure are connected to each other by a fold line, the relative positioning of these two flaps does not pose any difficulty.
Enfin, il s'avère finalement que la continuité de matière au niveau de la ligne de pliage améliore la résistance mécanique de la structure selon l'invention, alors qu'on aurait pu craindre une diminution de résistance du fait de ce pliage. Finally, it finally turns out that the continuity of material at the level of the fold line improves the mechanical resistance of the structure according to the invention, whereas one might have feared a reduction in resistance due to this folding.
Dans des modes de réalisation préférés de l'inven- tion, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :
-la plaque rigide formant la coque est réalisée en métal ;
-la plaque rigide formant la coque est réalisée en matériau composite ;

-le matériau composite comprend une matrice en matière synthétique dans laquelle sont noyées des fibres de renfort, ledit matériau étant exempt de fibres de renfort au niveau de la ligne de pliage ;
-les reliefs du premier volet comprennent au moins une nervure périphérique en forme d'auge qui suit le contour dudit premier volet et qui fait saillie à l'opposé du deuxième volet, cette nervure périphérique délimitant intérieurement un canal périphérique creux ;
-les reliefs du premier volet comprennent en outre au moins une nervure complémentaire en forme d'auge qui fait saillie à l'opposé du deuxième volet et qui relie l'un à l'autre deux côtés opposés de la nervure périphéri- que, cette nervure complémentaire délimitant un canal in térieur creux qui s'étend entre deux extrémités débouchant dans le canal intérieur creux délimité par la nervure pé riphérique ;

D'autres caractéristiques et avantages de l'inven- tion apparaîtront au cours de la description suivante d'une de ses formes de réalisation, donnée à titre d'exem- ple non limitatif, en regard des dessins joints. Other characteristics and advantages of the invention will appear during the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings.
Sur les dessins :
-la figure 1 est une vue en perspective d'un siège dont le dossier est équipé d'une structure selon une forme de réalisation de l'invention,
-la figure 2 est une vue en perspective de la structure en forme de coque équipant le dossier du siège de la figure 1, en cours de fabrication,
-et la figure 3 est une vue en coupe selon la ligne III-III de la figure 2, une fois la structure terminée.In the drawings:
FIG. 1 is a perspective view of a seat, the back of which is equipped with a structure according to an embodiment of the invention,
FIG. 2 is a perspective view of the shell-shaped structure fitted to the seat backrest of FIG. 1, during manufacture,
-and Figure 3 is a sectional view along line III-III of Figure 2, once the structure completed.
Sur les différentes figures, les mmes références désignent des éléments identiques ou similaires. In the various figures, the same references designate identical or similar elements.
La figure 1 représente un siège de véhicule automobile 1, en l'occurrence une banquette arrière, qui comprend une assise 2 et un dossier 3. Dans l'exemple particulier considéré ici, le dossier 3 comprend deux parties 4,5, qui forment respectivement environ 2/3 et 1/3 de la largeur du dossier 3, et qui sont rabattables vers l'avant indépendamment l'une de l'autre. FIG. 1 represents a motor vehicle seat 1, in this case a rear bench seat, which comprises a seat 2 and a backrest 3. In the particular example considered here, the backrest 3 comprises two parts 4,5, which respectively form approximately 2/3 and 1/3 of the width of the backrest 3, which can be folded forward independently of each other.
Comme représenté sur les figures 2 et 3, la structure, respectivement 6,7 de chacune des deux parties 4,5 du dossier, est constituée par une coque rigide en forme de caisson creux. As shown in FIGS. 2 and 3, the structure, respectively 6.7 of each of the two parts 4.5 of the backrest, consists of a rigid shell in the form of a hollow box.
Plus particulièrement, la coque rigide formant chacune des structures 6,7 est constituée par une seule plaque rigide, réalisée par exemple en métal (acier, aluminium, etc.) ou en matériau composite comprenant des fibres de renfort (fibres de verre, fibres de carbone, etc.) noyées dans une matrice en matière synthétique. More particularly, the rigid shell forming each of the structures 6,7 is constituted by a single rigid plate, made for example from metal (steel, aluminum, etc.) or from a composite material comprising reinforcing fibers (glass fibers, carbon, etc.) embedded in a plastic matrix.
Cette plaque rigide est repliée sur elle-mme selon une ligne de pliage, respectivement 8,9, en formant des premier et deuxième volets, respectivement 10, 11 et 12,13, qui présentent des contours identiques et qui sont rabattus l'un contre l'autre en correspondance mutuelle avant d'tre solidarisés l'un à l'autre par collage, soudage, rivetage, ou autres. This rigid plate is folded back on itself along a fold line, respectively 8.9, forming first and second flaps, respectively 10, 11 and 12.13, which have identical contours and which are folded one against the other. the other in mutual correspondence before being joined to one another by bonding, welding, riveting, or the like.
Lorsque la structure 6,7 est en matériau composite, ce matériau comporte de préférence uniquement, au niveau de la ligne de pliage 8,9, de fibres de renfort parallèles à ladite ligne de pliage. Avantageusement, le matériau composite est mme exempt de toute fibre de renfort au niveau de la ligne de pliage 8,9. When the structure 6,7 is made of composite material, this material preferably only comprises, at the level of the fold line 8,9, reinforcing fibers parallel to said fold line. Advantageously, the composite material is even free from any reinforcing fiber at the fold line 8, 9.
Par ailleurs, dans l'exemple particulier représen- té sur les dessins, la forme de caisson creux de la structure en forme de coque 6,7 est définie par des reliefs du premier volet 10,11 de cette structure, le deuxième volet 12,13 présentant quant à lui une forme plane, de préfé- rence dépourvue d'évidement. Furthermore, in the particular example shown in the drawings, the shape of the hollow box of the shell-shaped structure 6,7 is defined by reliefs of the first flap 10,11 of this structure, the second flap 12, 13 having a flat shape, preferably without a recess.
Plus particulièrement, les reliefs du premier volet comprennent au moins une nervure périphérique 14,15 en forme d'auge qui suit le contour dudit premier volet sur ses quatre côtés et qui fait saillie à l'opposé du deuxième volet 12,13. Cette nervure périphérique 14,15 comprend un fond 16 et deux parois latérales 17 délimitant intérieurement un canal périphérique creux 18. More particularly, the reliefs of the first flap comprise at least one peripheral rib 14, 15 in the form of a trough which follows the outline of said first flap on its four sides and which projects away from the second flap 12, 13. This peripheral rib 14, 15 comprises a bottom 16 and two side walls 17 internally delimiting a hollow peripheral channel 18.
Avantageusement, les reliefs du premier volet 10 de la structure 6 la plus large comprennent en outre au moins une nervure complémentaire 19 en forme d'auge qui fait saillie à l'opposé du deuxième volet 12 et qui relie l'un à l'autre deux côtés opposés de la nervure périphéri- que 14. Cette nervure complémentaire 19 comprend un fond 20 et deux parois latérales 21 délimitant un canal intérieur creux 22 qui s'étend entre deux extrémités débou- chant dans le canal intérieur creux 18 délimité par la nervure périphérique. Advantageously, the reliefs of the first flap 10 of the widest structure 6 further comprise at least one complementary rib 19 in the form of a trough which projects away from the second flap 12 and which connects to one another two opposite sides of the peripheral rib 14. This complementary rib 19 comprises a bottom 20 and two side walls 21 defining a hollow interior channel 22 which extends between two ends opening into the hollow interior channel 18 delimited by the rib peripheral.
Enfin, le premier volet 15 de la structure 7 la moins large comporte un évidement 23 au centre de la nervure périphérique 15, tandis que le premier volet 14 de la structure 6 la plus large comporte deux évidements 24,25 au centre de la nervure périphérique 14, ces deux évidements étant séparés par la nervure complémentaire 19. Finally, the first flap 15 of the narrower structure 7 has a recess 23 at the center of the peripheral rib 15, while the first flap 14 of the widest structure 6 has two recesses 24.25 at the center of the peripheral rib 14, these two recesses being separated by the complementary rib 19.
De préférence, les différentes nervures 14,15,19 de chaque structure 6,7 sont bordées de chaque côté par des rebords périphériques 26,27,28,29,30 qui s'éten- dent parallèlement au deuxième volet correspondant 12,13 et qui facilitent la fixation des premier et deuxième volets l'un sur l'autre. Preferably, the different ribs 14, 15, 19 of each structure 6, 7 are bordered on each side by peripheral edges 26, 27, 28, 29, 30 which extend parallel to the corresponding second flap 12, 13 and which facilitate the fixing of the first and second flaps one on the other.
