Description

SIEGE NOTAMMENT POUR VEHICULE AUTOMOBILE
L'invention concerne un siège, notamment pour véhicule automobile, constitué par un support d'assise et un support de dossier, individuellement ajustables en inclinaison, et montés conjointement sur des glissières de réglage.SEAT IN PARTICULAR FOR A MOTOR VEHICLE
The invention relates to a seat, in particular for a motor vehicle, consisting of a seat support and a backrest support, individually adjustable in inclination, and mounted jointly on adjustment slides.

La publication FR-A-2.561.182 décrit un tel siège dont le dossier est constitué par une partie inférieure porteur de parties latérales, une partie centrale, et une partie supérieure ayant fonction d'appui-tête. L'ensemble étant réglable indépendamment.The publication FR-A-2,561,182 describes such a seat, the back of which consists of a lower part carrying lateral parts, a central part, and an upper part having the function of headrest. The whole being independently adjustable.

Un tel siège permet de s'adapter aux impératifs physiques de chaque passager, au prix d'une mécanique complexe et de commandes électriques, augmentant par conséquent le coût dudit siège tout en limitant les possibilités de polyvalence de ce dernier. Le nombre important de réglages diminue la facilité d'utilisation d'un tel système.Such a seat makes it possible to adapt to the physical requirements of each passenger, at the cost of complex mechanics and electrical controls, consequently increasing the cost of said seat while limiting the possibilities of versatility of the latter. The large number of settings reduces the ease of use of such a system.

Afin de remédier à ces inconvénients, l'invention a pour objet un siège qui a des possibilités d'adaptation à la morphologie des passagers en utilisant des moyens simples et peu onéreux, tout en procurant une modularité accrue de la fonctionnalité du siège.In order to remedy these drawbacks, the invention relates to a seat which has possibilities of adaptation to the morphology of the passengers using simple and inexpensive means, while providing increased modularity of the functionality of the seat.

Selon l'invention, des longerons du support de l'assise sont munis de paliers, porteurs des montants latéraux du support de dossier, répartis de part et d'autre d'un plan de symétrie longitudinal de l'assise du siège, et localisés à l'avant et à l'arrière desdits longerons.According to the invention, side rails of the seat support are provided with bearings, carrying the lateral uprights of the backrest support, distributed on either side of a longitudinal plane of symmetry of the seat seat, and located at the front and rear of said beams.

Le siège ainsi réalisé permet de modifier les zones d'appui et de maintien au niveau du dos et de l'assise en déplaçant des éléments de soutien ou en changeant leurs orientations.The seat thus produced makes it possible to modify the support and support zones at the level of the back and of the seat by moving support elements or by changing their orientations.

Le siège ainsi réalisé permet également de changer le sens du siège en montant le dossier à l'avant ou à l'arrière du support d'assise.The seat thus produced also makes it possible to change the direction of the seat by mounting the backrest at the front or at the rear of the seat support.

Un autre avantage d'un tel siège réside dans le fait que les supports d'assise et de dossier peuvent recevoir, en lieu et place des éléments de soutien, des éléments ayant des fonctions utilitaires. Another advantage of such a seat lies in the fact that the seat and back supports can receive, in place of the support elements, elements having utility functions.

En se rapportant aux figures 1 à 2, le siège 1 est constitué d'un support d'assise 2 ajustable en inclinaison, par l'intermédiaire d'un moyen de commande 11 manuel ou motorisé, monté à rotation autour d'un axe transversal 12 porté par des glissières de réglage 15, et d'un dossier 3 réglable en inclinaison par rapport à l'assise 2 dudit siège 1. Le support d'assise 20 est constitué de longerons 21 munis de paliers 22, porteurs des montants latéraux 31 du support de dossier 30, répartis de part et d'autre du plan de symétrie longitudinal P de l'assise 2 du siège 1, et localisés à l'avant et à l'arrière desdits longerons 21.Referring to Figures 1 to 2, the seat 1 consists of a seat support 2 adjustable in inclination, by means of a manual or motorized control means 11, mounted for rotation about a transverse axis 12 carried by adjustment slides 15, and a backrest 3 adjustable in inclination relative to the seat 2 of said seat 1. The seat support 20 consists of side members 21 provided with bearings 22, carrying the lateral uprights 31 of the backrest support 30, distributed on either side of the longitudinal plane of symmetry P of the seat 2 of the seat 1, and located at the front and at the rear of said longitudinal members 21.

En se rapportant à la figure 3, le support de dossier 30 est constitué de deux montants 31 indépendants qui comportent à leurs extrémités inférieures un pied d'assemblage 32 porteur de crants 33 en coopération avec les dentures 23 des paliers 22 porteurs desdits montants latéraux 31. Referring to Figure 3, the backrest support 30 consists of two independent uprights 31 which have at their lower ends an assembly foot 32 bearing notches 33 in cooperation with the teeth 23 of the bearings 22 carrying said lateral uprights 31 .

Le pied d'assemblage 32 a la forme d'un segment circulaire creux dans lequel est monté à coulissement un pêne 34 de même géométrie, ce dernier est muni d'un bouton de commande 35, guidé par une lumière 36 réalisée dans le pied 32 du montant et permettant de produire une course angulaire dudit pêne 34. La position sortie du pêne 34 enveloppe le palier 22, produisant ainsi l'immobilisation du montant 31 sur ledit palier 22, dans la position d'utilisation souhaitée.The assembly foot 32 has the shape of a hollow circular segment in which is slidably mounted a bolt 34 of the same geometry, the latter is provided with a control button 35, guided by a light 36 produced in the foot 32 of the upright and making it possible to produce an angular travel of said bolt 34. The extended position of the bolt 34 envelops the bearing 22, thus producing the immobilization of the upright 31 on said bearing 22, in the desired position of use.

L'assise 2 et le dossier 3 sont constitués d'une pluralité d'éléments de soutien 4 et 5 empilables et amovibles, ces derniers comportent une armature intérieure 40 et 50 qui permet d'entretoiser les montants 31 du support de dossier 30 et les longerons 21 du support d'assise 20. Un élément de rembourrage fixe 6 est prévu au niveau de l'axe 12 de rotation de l'assise 2.The seat 2 and the backrest 3 consist of a plurality of support elements 4 and 5 stackable and removable, the latter have an internal frame 40 and 50 which makes it possible to brace the uprights 31 of the backrest support 30 and the side members 21 of the seat support 20. A fixed padding element 6 is provided at the axis 12 of rotation of the seat 2.

En se rapportant aux figures 4 et 5, les éléments de soutien 4 et 5 peuvent avoir une forme excentrée par rapport aux axes 41 et 51 des armatures ce qui permet, par retournement de 1800 de l'élément, de faire varier le relief de l'assise 2 et du dossier 3 et de modifier la position des points d'appui au niveau du dos et de l'assise du passager.Referring to Figures 4 and 5, the support elements 4 and 5 may have an eccentric shape relative to the axes 41 and 51 of the frames which allows, by inversion of 1800 of the element, to vary the relief of the seat 2 and backrest 3 and modify the position of the support points at the back and the passenger seat.

Les éléments de soutien 4 du dossier 3 sont portés par une armature intérieure 40 munie à chaque extrémité d'une partie tubulaire 42 qui coopère avec un montant 31 du support de dossier 30. Les éléments de soutien 5 du support d'assise 20 sont portés par une armature intérieure 50 munie à chaque extrémité d'un embout rainuré 52 qui coopère avec une nervure 24 du longeron 21.The support elements 4 of the backrest 3 are carried by an internal frame 40 provided at each end with a tubular part 42 which cooperates with an upright 31 of the backrest support 30. The support elements 5 of the seat support 20 are carried by an internal frame 50 provided at each end with a grooved end piece 52 which cooperates with a rib 24 of the spar 21.

Afin d'assurer un bon confort au passager, les éléments de soutien 4 et 5, constituant le dossier 3 et l'assise 2, sont munis d'une armature 40 et 50 ayant des caractéristiques élastiques. Pour permettre une bonne rigidité structurelle du dossier 3 et de l'assise 2, les éléments de soutien terminaux 45 et 55 ont une armature rigide.In order to ensure good comfort for the passenger, the support elements 4 and 5, constituting the backrest 3 and the seat 2, are provided with a frame 40 and 50 having elastic characteristics. To allow good structural rigidity of the backrest 3 and of the seat 2, the terminal support elements 45 and 55 have a rigid frame.

Les supports d'assise et de dossier ont la possibilité de recevoir en lieu et place des éléments de soutien 4 et 5, des éléments ayant une fonction utilitaire. Un exemple de réalisation de tels éléments est représenté à la figure 6, les montants 31 du support de dossier et les longerons 21 du support d'assise 20 peuvent recevoir chacun un plateau 7 et 70 porteur de fixations diverses, telles que passe sangle 71 et support de roue 72, en vue du transport de matériel. Les plateaux 7 et 70 sont munis de moyens de liaisons qui permettent leurs adaptations sur les longerons 21 du support d'assise 20 ou sur les montants 31 du support de dossier 30.The seat and back supports have the possibility of receiving instead of support elements 4 and 5, elements having a utility function. An exemplary embodiment of such elements is shown in FIG. 6, the uprights 31 of the back support and the side members 21 of the seat support 20 can each receive a plate 7 and 70 carrying various fixings, such as strap pass 71 and wheel support 72, for transporting equipment. The plates 7 and 70 are provided with connection means which allow their adaptations to the side members 21 of the seat support 20 or to the uprights 31 of the file support 30.

La conception du siège 1 permet l'utilisation éventuelle du dossier 300, d'un autre siège 100 du véhicule 8, afin de transformer en couchette ledit siège 1. La transformation s'effectue en procédant à l'assemblage du dossier 300 sur les paliers 22 situés à l'avant du support d'assise 20, tel que représenté à la figure 7.The design of seat 1 allows the possible use of the backrest 300, of another seat 100 of the vehicle 8, in order to transform said seat 1 into a berth. The transformation is carried out by assembling the backrest 300 on the bearings 22 located at the front of the seat support 20, as shown in FIG. 7.

La possibilité de permuter les éléments de soutien 4 et 5 permet de modifier l'esthétique du siège en utilisant des éléments de couleurs différentes.The possibility of swapping the support elements 4 and 5 makes it possible to modify the aesthetics of the seat by using elements of different colors.

L'invention n'est nullement limitée au mode de réalisation et aux transformations décrites à titre d'exemple. The invention is in no way limited to the embodiment and to the transformations described by way of example.
