Description

<B>STRUCTURE DE SUPPORT POUR DOSSIER</B> <B>DE</B> SIEGE <B>DE</B> VEHICULE, <B>NOTAMMENT AUTOMOBILE</B> La présente invention concerne une structure de support de garnissage pour dossier de siège de véhicule, notamment automobile, et plus particulièrement une telle structure comprenant des moyens de liaison à une armature de dossier. BACKGROUND OF THE INVENTION [0001] The present invention relates to a lining support structure for vehicle seat back, particularly automobile, and more particularly such a structure comprising connecting means to a backrest frame.

D'une manière générale les sièges automobiles comprennent principalement une armature rigide, qui supporte garnissages de sièges, constitués la plupart du temps de mousse recouverte de textile ou de cuir, par l'intermédiaire de nappes plus ou moins élastiques généralement planes, métalliques ou textiles, tendues entre les montants desdites armatures par l'intermédiaire d'une pluralité de ressorts de traction. In general, the car seats mainly comprise a rigid frame, which supports upholstered seats, consisting mostly of foam covered with textile or leather, via more or less elastic sheets generally flat, metal or textile tensioned between the uprights of said reinforcement by means of a plurality of tension springs.

De tels agencements procurent un bon niveau de confort mais réagissent globalement comme des ressorts parfaits si l'on néglige les quelques frottements et le faible hystérésis composants couramment employés. Such arrangements provide a good level of comfort but react globally as perfect springs if we neglect the few friction and low hysteresis components commonly used.

La plupart des sièges actuels comporte armature de dossier en forme de U inversé dont les branches sont reliées au système de réglage en inclinaison du dossier par rapport à l'armature d'assise. La barre horizontale du U formant traverse située sensiblement niveau des épaules supporte ou constitue en tout ou pour partie, l'armature en zone appui-tête. Un tel agencement ne permet pas l'implantation des nappes de soutien precitées dans cetie zone et l'on trouve donc généralement une faible épaisseur de mousse directement en appui sur ladite traverse. Most of the current seats have an inverted U-shaped backrest whose branches are connected to the backrest tilt adjustment system relative to the seat frame. The horizontal bar of the U forming a cross member substantially at shoulder level supports or constitutes in whole or in part, the armature in the headrest zone. Such an arrangement does not allow the implementation of the aforementioned support plies in this area and therefore there is generally a small thickness of foam directly bearing on said cross.

D'autre part, des études ergonomiques montrent qu'en position optimum de conduite, la tête du conducteur ne repose jamais sur le coussin d'appui-tête, contrairement au bas de son sur le coussin de dossier. II résulte qu'en cas de chocs par l'arrière du véhicule, après s'être violemment enfoncées dans le dossier du siège sous l'effet de l'accélération transmise au siège par l'intermédiaire du châssis, les différentes parties du corps de l'occupant dudit siège rebondissent avec une violence proportionnelle à la raideur du garnissage qu'elles contactent ou viennent contacter. On the other hand, ergonomic studies show that in the optimum driving position, the driver's head never rests on the headrest cushion, unlike the lower one on the backrest cushion. It follows that in case of shocks from the rear of the vehicle, after violently driven into the seat back under the effect of the acceleration transmitted to the seat via the frame, the various parts of the body of the occupant of said seat bounce with a proportional violence to the stiffness of the lining they contact or come to contact.

On comprendra que la partie supérieure du torse de l'occupant rebondira violemment et prématurément du fait de la faible épaisseur du garnissage dans cette zone. A contrario, la tête dudit occupant, qui n'était pas en contact avec le coussin d'appui-tete rebondira plus tardivement et avec plus ou moins de violence fonction de la souplesse de l'armature dudit appui-tête et de la conception de son garnissage. It will be understood that the upper torso of the occupant will rebound violently and prematurely due to the small thickness of the lining in this area. On the other hand, the head of said occupant, which was not in contact with the headrest cushion, will bounce back later and with more or less violence depending on the flexibility of the armature of said headrest and the design of the headrest. its lining.

Ce déphasage de rebond tête / torse qui se traduit par un déplacement relatif entre les vertèbres cervicales est identifié comme étant la principale cause de lésions en cas de chocs par l'arrière d'un véhicule par un autre avec une vitesse différentielle inférieure à 20 km/h II en résulte donc que la sécurité peut être améliorée si l'on peut synchroniser les déplacements de la tête par rapport au torse pendant toutes les phases du choc. This head / torso rebound shift resulting in relative movement between the cervical vertebrae is identified as the main cause of injury in case of shocks from the rear of one vehicle by another with a differential speed of less than 20 km. As a result, security can be improved if the movements of the head relative to the torso can be synchronized during all phases of the impact.

La présente invention vise à pallier ces inconvénients. The present invention aims to overcome these disadvantages.

Plus particulièrement, l'invention a pour but de fournir des moyens permettant d'éviter, ou pour le moins de limiter, le rebond du torse de l'occupant d'un siège de véhicule sous l'effet d'un choc arrière, et les lésions cervicales qui peuvent en résulter. More particularly, the object of the invention is to provide means making it possible to avoid, or at least limit, the rebound of the torso of the occupant of a vehicle seat under the effect of a rear impact, and the cervical lesions that can result.

A cet effet, l'invention a pour objet une structure de support de garnissage pour dossier de siège de véhicule, notamment automobile, comprenant des moyens de liaison à une armature de dossier, caractérisée par le fait que lesdits moyens de liaison comprennent des organes susceptibles de s'allonger avec absorption d'énergie lorsqu'ils sont soumis à une traction supérieure à un seuil prédéterminé. For this purpose, the subject of the invention is a lining support structure for a vehicle seat back, in particular an automobile seat, comprising means for connecting to a backrest frame, characterized in that the said connecting means comprise members that can to elongate with energy absorption when subjected to traction greater than a predetermined threshold.

Dans un mode de réalisation particulier, lesdits organes comprennent un crochet monté sur ladite structure, respectivement sur ladite armature, encagé dans un orifice d'une pièce plate monté sur ladite armature, respectivement sur ladite structure, ladite pièce plate comportant une ligne de déchirure partant dudit orifice dans la direction de la traction de la structure sur l'armature. Plus particulièrement, ladite pièce plate peut être réalisée en matière plastique et ladite ligne de déchirure est formée d'une rainure formée dans l'épaisseur de ladite pièce. In a particular embodiment, said members comprise a hook mounted on said structure, respectively on said frame, encaged in a hole of a flat part mounted on said frame, respectively on said structure, said flat piece having a tear line starting said orifice in the direction of traction of the structure on the frame. More particularly, said flat piece may be made of plastic and said tear line is formed of a groove formed in the thickness of said piece.

Ladite pièce plate peut en outre comprendre un renfort à l'extrémité de ladite ligne de déchirure opposée audit orifice. Said flat piece may further comprise a reinforcement at the end of said tear line opposite said orifice.

On peut en en outre prévoir des moyens élastiques série avec lesdits organes susceptibles de s'allonger. In addition, it is possible to provide series elastic means with said members capable of lengthening.

Plus particulièrement, on peut également prévoir des moyens de blocage desdits moyens élastiques dans leur état contraint. Egalement dans un mode de réalisation particulier de l'invention, ladite structure peut également comprendre une nappe de support ou un plateau généralement rigide supportés à partir de ladite armature par lesdits organes de liaison. More particularly, it is also possible to provide means for locking said elastic means in their constrained state. Also in a particular embodiment of the invention, said structure may also comprise a support ply or a generally rigid plate supported from said armature by said connecting members.

On décrira maintenant, à titre d'exemple non limitatif, des modes de réalisation particuliers de l'invention, en référence aux dessins schématiques annexés dans lesquels - la figure 1 est une vue en perspective d'un premier mode de réalisation du plateau d'un dossier de siège de véhicule automobile ; la figure 2 est une vue en perspective d'un deuxième mode de réalisation de ce plateau ; la figure 3 est une demi coupe horizontale du dossier de ce siège la figure 4 est une vue de détail en perspective d'un élément de structure de support du plateau ; - la figure 5 est une vue en coupe selon la ligne V de la figure 4 ; la figure 6 est une vue similaire à la figure 3 d'un autre mode de réalisation ; et la figure 7 est une vue de détail d'un agencement susceptible d'être utilisé dans le dossier de la figure 6. By way of nonlimiting example, particular embodiments of the invention will now be described with reference to the appended diagrammatic drawings in which - FIG. 1 is a perspective view of a first embodiment of the tray of FIG. a motor vehicle seat back; Figure 2 is a perspective view of a second embodiment of this plate; Figure 3 is a half horizontal section of the back of this seat Figure 4 is a detail view in perspective of a support structure element of the plate; - Figure 5 is a sectional view along the line V of Figure 4; Figure 6 is a view similar to Figure 3 of another embodiment; and FIG. 7 is a detailed view of an arrangement that can be used in the folder of FIG. 6.

On voit à la figure 1 un plateau 1 de support de garnissage pour dossier de siège de véhicule automobile. Ce plateau monté comme cela sera décrit ci-après sur la structure du dossier, cette dernière comprenant deux montants latéraux 2 (figures 3 et 6) réunis par une traverse supérieure pour former une armature en U inversé. FIG. 1 shows a lining support tray 1 for a motor vehicle seat back. This plate mounted as will be described below on the structure of the backrest, the latter comprising two lateral uprights 2 (3 and 6) joined by a top rail to form an inverted U-shaped frame.

Le plateau 1 comporte une extension vers le haut 3 formant une armature d'appui-tête. L'ensemble constitué par le plateau 1 et l'armature du dossier est muni de façon connue d'une garniture en mousse 4 et d'un revêtement extérieur 5, par exemple textile. The plate 1 has an upward extension 3 forming a headrest frame. The assembly constituted by the plate 1 and the frame of the backrest is provided in known manner with a foam lining 4 and an outer covering 5, for example textile.

Les ailes 6 du plateau 1 sont en appui sur les montants latéraux 2 de l'armature du siège et sont reliées à la partie centrale du plateau par une zone élastique de sorte que, lorsque le plateau recule par rapport à l'armature comme cela se produit lors d'un choc arrière, les ailes 6 se referment, maintenant ainsi latéralement l'occupant du siège. Les zones élastiques de liaison peuvent d'ailleurs être prévues pour se déformer plastiquement en cas choc violent de manière à absorber une partie de l'énergie. The wings 6 of the plate 1 bear against the lateral uprights 2 of the seat frame and are connected to the central part of the plate by an elastic zone so that when the plate moves back with respect to the frame as produced during a rear impact, the wings 6 close again, thus maintaining laterally the occupant of the seat. Elastic bonding zones may also be provided to deform plastically in violent shock case so as to absorb a portion of the energy.

Le plateau 1 comporte sur sa face arrière des saillies 7 formant des entretoises dans lesquelles coulissent des sangles 8. extrémités des sangles 8 sont reliées aux montants latéraux 2 l'armature du siège par des tringles 9 pouvant comporter une partie 10 formant ressort. The plate 1 has on its rear face projections 7 forming struts in which the webs slide 8. ends of the straps 8 are connected to the lateral uprights 2 the frame of the seat by rods 9 may comprise a portion 10 forming a spring.

Les extrémités des tringles 9 forment un crochet 11 engage dans un orifice 12 de la sangle 8. L'orifice 12 se prolonge en direction de l'extrémité de la sangle 8 par une rainure 13 à section en V formant une ligne de déchirure se terminant par un renfort évitant en cas de choc suffisamment violent une déchirure complète de la sangle 8. The ends of the rods 9 form a hook 11 engages in an orifice 12 of the strap 8. The orifice 12 extends towards the end of the strap 8 by a groove 13 with a V-shaped section forming a tear line ending by a reinforcement avoiding in case of shock sufficiently violent a complete tear of the strap 8.

Par conséquent, en cas de choc, le plateau 1 recule et ressort 10 commence par se tendre puis, si la traction est maintenue par la violence du choc, la ligne 10 se déchire jusqu'au renfort 14 en absorbant une partie de l'énergie, limitant ainsi l'effet de rebond. Therefore, in the event of a shock, the plate 1 moves backward and starts to stretch then, if the traction is maintained by the force of the shock, the line 10 tears up to the reinforcement 14, absorbing part of the energy , thus limiting the rebound effect.

Dans le mode de réalisation des figures 6 et 7, une tringle est munie d'un ressort central 10' et reçoit les entretoises 7. Les extrémités de la tringle 9' sont reliées comme précédemment à tronçons de sangle 8' dont une extrémité est fixée aux montants 2 de l'armature du siège et dont l'autre extrémité est munie d'une ligne de déchirure. In the embodiment of FIGS. 6 and 7, a bead wire is provided with a central spring 10 'and receives the spacers 7. The ends of the bead wire 9' are connected as previously to belt sections 8 ', one end of which is fixed. to the uprights 2 of the frame of the seat and whose other end is provided with a tear line.

Cet agencement fonctionne comme celui de la figure 3. On a prévu à la figure 7, au dos de la plaque 1, des formes d'encliquetage qui reçoivent les extrémités du ressort 10' lorsque celui-ci est suffisamment distendu sous l'effet d'un choc violent. Une partie de l'énergie du choc est donc emmagasinée dans le ressort sous la forme d'énergie potentielle et ne peut pas être restituée au plateau . On limite ainsi également l'effet de rebond. This arrangement functions like that of FIG. 3. In FIG. 7, on the back of the plate 1, latching shapes are provided which receive the ends of the spring 10 'when the latter is sufficiently distended under the effect of FIG. a violent shock. Part of the shock energy is stored in the spring in the form of potential energy and can not be restored to the plateau. This also limits the rebound effect.

La figure 2 illustre une variante 1' du plateau de la figure 1. L'armature 3' de l'appui-tête est ici rapportée ' l'aide de deux broches engagées dans des gaines 17 réalisées d'une seule pièce avec la partie basse 18 du plateau 1'. L'appui-tête peut ainsi être réglable hauteur. FIG. 2 illustrates a variant 1 'of the plate of FIG. 1. The reinforcement 3' of the headrest is here reported by means of two pins engaged in sheaths 17 made in one piece with the part bottom 18 of the plate 1 '. The headrest can thus be adjustable height.

ailleurs, les ailes 6' du plateau 1' sont ici munies de renfoncements 19 formant des cavités de logement pour des coussins gonflables de sécurité. elsewhere, the wings 6 'of the plate 1' are here provided with recesses 19 forming housing cavities for airbags.

Dans les deux cas (figures 1 et 2), il est prévu un bouton de réglage 20 de la convexité du plateau, et donc du dossier. In both cases (FIGS. 1 and 2), there is provided a knob 20 for adjusting the convexity of the plate, and therefore of the backrest.

A cet effet, le bouton 20 est monté sur l'armature du siège et est relié par une tige 21 à une came 22 en appui sur le dos du plateau. Ainsi, une rotation du bouton 20 entraîne modification de la convexité du plateau. For this purpose, the button 20 is mounted on the armature of the seat and is connected by a rod 21 to a cam 22 resting on the back of the plate. Thus, a rotation of the knob 20 causes the convexity of the plate to change.

On observera que l'on a décrit l'utilisation d'organes susceptibles de s'allonger avec absorption d'énergie comme moyens de suspension d'un plateau rigide. Toutefois, cet agencement peut trouver une application directe sur les sièges traditionnels pour supporter les nappes en intercalant de telles organes soit entre nappe et ressort ou entre ressort et armature.It will be observed that the use of energy-absorbing elongate members has been described as a means of suspending a rigid plate. However, this arrangement can find a direct application on traditional seats to support the plies by interposing such bodies either between the ply and spring or between spring and frame.
