Description
ta présente invention se rapporte aux armatures de sièges de véhicules automobiles, en particulier de sièges arrière. your present invention relates to the frames of motor vehicle seats, in particular rear seats.
Le but de l'invention est de réaliser une armature de siège de véhicule automobile qui soit d'une construction simple et économique et d'un montage facile et rapide. The object of the invention is to provide a motor vehicle seat frame which is simple and economical in construction and easy and quick to assemble.
L'armature selon l'invention est caractérisée en ce qu'elle comprend un premier support pour la partie assise du siège, réalisé en matière plastique, un deuxième support pour le dossier du siège, également réalisé en matière plastique, une paire de charnières latérales servant à articuler les deux supports l'un sur l'autre autour d'un axe transversal horizontal adjacent au bord inférieur du dossier, chaque charnière comprenant deux éléments métalliques articulés l'un sur l'autre et fixés respectivement aux deux supports, et une paire de pattes de fixation destinées à être fixées à la caisse du véhicule et articulées sur le premier support pour tourner autour d'un axe transversal horizontal commun adjacent au bord avant de la partie assise du siège. The frame according to the invention is characterized in that it comprises a first support for the seat part of the seat, made of plastic, a second support for the seat back, also made of plastic, a pair of side hinges used to articulate the two supports one on the other about a horizontal transverse axis adjacent to the lower edge of the backrest, each hinge comprising two metal elements articulated one on the other and fixed respectively to the two supports, and a pair of fixing lugs intended to be fixed to the vehicle body and articulated on the first support to rotate around a common horizontal transverse axis adjacent to the front edge of the seat part of the seat.
Dans la présente description et dans les revendications qui suivent, le terme "transversal" désigne une direction qui est perpendiculaire au plan vertical longitudinal du véhicule automobile dans l'état de montage du siège sur le véhicule. In the present description and in the claims which follow, the term "transverse" designates a direction which is perpendicular to the longitudinal vertical plane of the motor vehicle in the state of mounting of the seat on the vehicle.
Les deux supports en matière plastique présentent de préférence chacun un corps en forme de cuvette destiné à recevoir et à supporter le rembourrage du siège. Le corps en cuvette de chaque support présente un fond qui possède une série de nervures de raidissement. The two plastic supports preferably each have a bowl-shaped body intended to receive and support the padding of the seat. The bowl body of each support has a bottom which has a series of stiffening ribs.
En outre, le deuxième support présente au moins une traverse métallique de raidissement à proximité du bord supérieur du dossier.In addition, the second support has at least one metal stiffening cross member near the upper edge of the backrest.
L'armature selon l'invention permet de réaliser un siège arrière pour véhicules automobiles dans lequel le dossier peut être rabattu vers l'avant jusqu'à atteindre une position sensiblement horizontale au-dessus de la partie assise du siège, pour permettre de basculer ensuite en avant l'ensemble de la partie assise et du dossier ainsi superposés vers une position sensiblement verticale, afin de permettre d'agrandir le plan de charge du véhicule. The frame according to the invention makes it possible to produce a rear seat for motor vehicles in which the backrest can be folded forward until it reaches a substantially horizontal position above the seat part of the seat, so that it can then be tilted. forward all of the seat part and the backrest thus superimposed towards a substantially vertical position, in order to allow the load plane of the vehicle to be enlarged.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de réalisation et en se référant aux dessins annexés sur lesquels,
la figure 1 est une vue en perspective d'une armature de siège selon l'invention
la figure 2 est une vue en coupe selon la ligne
II-II de la figure 1 ; et
la figure 3 est une vue à échelle agrandie d'un détail de la figure 2, indiqué par la flèche III sur cette dernière figure.Other characteristics and advantages of the invention will be better understood on reading the following description of an exemplary embodiment and with reference to the appended drawings in which,
Figure 1 is a perspective view of a seat frame according to the invention
Figure 2 is a sectional view along the line
II-II of Figure 1; and
Figure 3 is an enlarged view of a detail of Figure 2, indicated by arrow III in the latter figure.
Sur les dessins, le numéro de référence 1 désigne dans son ensemble une armature pour siège arrière de véhicule automobile. Le siège 1 comprend un premier support 2 pour la partie assise du siège, et un deuxième support 3 pour le dossier du siège. Les deux supports 2 et 3 sont réalisés en matière plastique et présentent un corps possédant la conformation d'une cuvette qui présente une paroi de fond 4, 5 munie de nervures de raidissement 6, 7. In the drawings, the reference number 1 designates as a whole a frame for a rear seat of a motor vehicle. The seat 1 comprises a first support 2 for the seat part of the seat, and a second support 3 for the seat back. The two supports 2 and 3 are made of plastic and have a body having the conformation of a bowl which has a bottom wall 4, 5 provided with stiffening ribs 6, 7.
L'armature 1 comprend en outre deux charnières latérales 8 servant à articuler les deux supports 2, 3 l'un sur l'autre pour leur permettre de tourner autour d'un axe transversal horizontal 9 adjacent au bord inférieur du dossier du siège. Chaque charnière 8 comprend deux éléments métalliques de charnière 10, 11 qui sont fixés respectivement aux deux supports 2, 3.En particulier, chaque élément métallique 10 comprend une partie de base 10a vissée sur le fond 4 du support 2 et chaque élément métallique ll présente une partie de base lla fixée aux deux ailes longitudinales 12 d'une traverse m & tallique de raidissement 13 (voir en particulier les figures 1, 2) qui présente une section transverale en ome- qa et qui est reçue un logement 14 défini dans le corps du support 3 dans une position adjacente au bord inférieur du dossier. Le corps du support 3 présente en outre un logement transversal allongé 1S; adjacent au bord supérieur du dossier, et dans lequel se place une traverse métallique de raidissement 16 qui est munie à ses ex trématés de plaques 17 servant à la fixer au bord du support 3 en matière plastique.Les plaques 17 servent également à supporter les habituels moyens d'accrochage du dossier sur la caisse, et qui servent eux-mêmes à bloquer le dossier dans la position active d'utilisation normale. Ces moyens sont d'un type connu en soi et ne rentrent pas dans le domaine de l'invention, de sorte qu'ils ne sont pas représentés sur les dessins annexés, ceci afin de rendre la compréhension de ces derniers plus rapide et plus facile. The frame 1 further comprises two lateral hinges 8 serving to articulate the two supports 2, 3 one on the other to allow them to rotate around a horizontal transverse axis 9 adjacent to the lower edge of the seat back. Each hinge 8 comprises two metal hinge elements 10, 11 which are respectively fixed to the two supports 2, 3. In particular, each metal element 10 comprises a base part 10a screwed onto the bottom 4 of the support 2 and each metal element ll has a base part 11a fixed to the two longitudinal wings 12 of a metal stiffening cross member 13 (see in particular FIGS. 1, 2) which has a cross section in omeqa and which is received a housing 14 defined in the support body 3 in a position adjacent to the lower edge of the backrest. The body of the support 3 also has an elongated transverse housing 1S; adjacent to the upper edge of the backrest, and in which is placed a metal stiffening crosspiece 16 which is provided at its ex-jellies with plates 17 serving to fix it to the edge of the support 3 made of plastic. The plates 17 are also used to support the usual means for attaching the file to the body, and which themselves serve to lock the file in the active position of normal use. These means are of a type known per se and do not fall within the scope of the invention, so that they are not shown in the accompanying drawings, this in order to make the understanding of these latter faster and easier. .
L'armature de siège comprend en outre une paire de pattes avant 18 munies de trous 19 destinés à recevoir des vis servant à les fixer à la caisse du véhicule ; ces pattes sont articulées sur la partie avant du corps en cuvette du premier support 2 pour tourner autour d'un axe transversal horizontal commun 20. The seat frame further comprises a pair of front legs 18 provided with holes 19 intended to receive screws used to fix them to the vehicle body; these legs are articulated on the front part of the bowl-shaped body of the first support 2 to rotate around a common horizontal transverse axis 20.
Les deux supports en cuvette 2, 3 sont destinés à recevoir le rembourrage de la partie assise et du dossier du siège, rembourrage qui est lui-même complété par le tissu extérieur de revêtement et par les éventuels moyens de suspension intérieure. The two bowl supports 2, 3 are intended to receive the padding of the seat part and of the seat back, padding which is itself supplemented by the external covering fabric and by the possible internal suspension means.
Ainsi qu'il ressort de façon évidente de la description qui précède, l'armature décrite ci-dessus permet de réaliser des sièges arrière de- véhicules automobiles du type dans lequel le siège peut être placé dans un état replié de faible encombrement pour agrandir le plan de charge du véhicule. Cette condition est obtenue en rabattant tout d'abord le dossier autour de l'axe d'articulation 9, dans un premier temps, pour ltamener dans une position sensiblement horizontale au-dessus de la partie assise du siège (le dossier et la partie assise sont représentés en lignes tiretées sur les dessins an nexés et désignés respectivement par les numéros de référence 21, 22) et, dans un deuxième temps, en basculant l'ensemble de la partie assise et du dossier ainsi superposés autour de l'axe d'articulation 20, pour les amener dans une position sensiblement-verticale. As is evident from the foregoing description, the frame described above makes it possible to produce rear seats for motor vehicles of the type in which the seat can be placed in a folded state with small dimensions to enlarge the vehicle load plan. This condition is obtained by first folding the backrest around the hinge pin 9, firstly, to bring it into a substantially horizontal position above the seat part of the seat (the backrest and the seat part are shown in dashed lines on the appended drawings and designated respectively by reference numbers 21, 22) and, in a second step, by tilting the entire seat part and the backrest thus superimposed around the axis of articulation 20, to bring them into a substantially vertical position.
Il ressort en outre de façon évidente de la description qui précède que la structure de l'armature de siège selon l'invention est d'une construction particu lièrement- simple et économique et qui permet en même temps un montage facile et rapide du siège. It is also evident from the foregoing description that the structure of the seat frame according to the invention is of a particularly simple and economical construction and which at the same time allows easy and rapid mounting of the seat.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of non-limiting example without departing from the scope of the invention.
