Description

La présente invention concerne un ensemble de relaxation du type canapé, fauteuil ou siège transformable, c'est-à-dire dont l'inclinaison relative entre l'assise, le dossier et les différents éléments associés est modifiable.The present invention relates to a relaxation assembly of the type sofa, chair or convertible seat, that is to say whose relative inclination between the seat, the backrest and the various associated elements is modifiable.

De nombreux ensembles de relaxation de ce type ont déjà été proposés.Many relaxation sets of this type have already been proposed.

On distingue notamment les sièges comportant un dossier inclinable vers l'arrière et dont l'appui-tête se redresse progressivement en fonction du degré d'inclinaison du dossier vers l'arrière afin que le regard de l'utilisateur installé dans ce type de siège reste constamment parallèle au sol. On trouvera un exemple de ces dispositifs dans le brevet US 3 929 374 , par exemple. Ces sièges ont pour inconvénient de nécessiter un dégagement suffisant à l'arrière, pour permettre le débattement du dossier lorsqu'on l'incline.In particular, the seats comprising a backrest reclining and whose headrest is gradually recovering depending on the degree of inclination of the backrest so that the eyes of the user installed in this type of seat remains constantly parallel to the ground. An example of these devices can be found in US Patent 3,929,374 , for example. These seats have the disadvantage of requiring sufficient clearance at the rear, to allow the movement of the backrest when tilted.

Un autre type de siège de relaxation est celui comportant un bâti fixe avec une assise mobile, coulissant généralement horizontalement, reliée à un dossier mobile et à un appuie-tête. Dans une première position où l'assise est totalement reculée, l'utilisateur se trouve en position assise normale et l'angle entre le dossier et l'assise est voisin de 90°. L'appuie-tête est généralement escamoté puisque l'utilisateur est en position active. Dans le cas contraire où l'utilisateur souhaite adopter une position plus relaxante, il déplace par un simple mouvement de son corps l'assise vers l'avant, ce qui incline le dossier de telle façon que l'angle entre le dossier et l'assise soit supérieur à 90°, tandis que simultanément l'appuie-tête est relevé et vient dans le prolongement du dossier. Les systèmes permettant le relèvement de l'appuie-tête mettent en oeuvre des jeux de bielles et de ressorts relativement complexes. On trouvera un exemple de ce type de siège de relaxation dans le modèle d'utilité allemand DE 89.04.775 U .Another type of relaxation seat is that comprising a fixed frame with a movable seat, sliding generally horizontally, connected to a movable backrest and a headrest. In a first position where the seat is fully retracted, the user is in a normal sitting position and the angle between the backrest and the seat is close to 90 °. The headrest is generally retracted since the user is in the active position. In the opposite case where the user wishes to adopt a more relaxing position, he moves with a simple movement of his body the seat forward, which inclines the backrest so that the angle between the backrest and the sitting is greater than 90 °, while simultaneously the headrest is raised and comes in the extension of the folder. The systems allowing the raising of the headrest implement sets of connecting rods and relatively complex springs. An example of this type of relaxation seat can be found in the utility model German DE 89.04.775 U .

Tous ces dispositifs connus, quelque soit leur type, ont pour inconvénient majeur de mettre en oeuvre des systèmes mécaniques complexes destinés à assurer un redressement progressif de l'appuie-tête en fonction du degré d'inclinaison du dossier.All these known devices, whatever their type, have the major disadvantage of implementing complex mechanical systems for ensuring a progressive recovery of the headrest depending on the degree of inclination of the backrest.

Habituellement, ces mécanismes d'articulation conditionnent beaucoup l'aspect général du siège, conduisant à un résultat à l'esthétique discutable. En outre, le nombre important de pièces requises augmente sensiblement le coût du siège par rapport à un siège non transformable ou comportant seulement une assise et un dossier mobile.Usually, these articulation mechanisms greatly condition the overall appearance of the seat, leading to a questionable aesthetic result. In addition, the large number of parts required substantially increases the cost of the seat compared to a non-convertible seat or having only a seat and a mobile backrest.

La présente invention vise donc à pallier ces inconvénients en proposant un ensemble de relaxation comportant un bâti fixe, qui est constitué notamment d'un dos globalement vertical, connecté à une base horizontale et à des éléments latéraux formant les joues dudit ensemble, elles-mêmes liées à la base, lequel bâti supporte au moins :

  • un élément d'assise mobile sensiblement horizontal, coulissant parallèlement à la base selon un axe arrière-avant,
  • un premier élément d'appui mobile, tel qu'un dossier ou un cale-rein, incliné par rapport à l'horizontale et articulé par son extrémité inférieure à l'extrémité arrière de l'élément d'assise de manière à s'incliner de haut en bas et d'arrière en avant,
  • un second élément d'appui mobile, tel qu'un dossier ou un appuie-tête, incliné par rapport à l'horizontal et articulé à l'extrémité supérieure du premier élément d'appui, chacun desdits éléments mobiles étant constitué d'au moins un coussin solidaire d'un support, ledit ensemble permettant de passer, grâce à une translation de l'élément d'assise, d'une position initiale où l'utilisateur est en position assise à une position de relaxation où l'utilisateur est en position semi-allongée et inversement ; cet ensemble de relaxation est remarquable en ce que il est muni de moyens de guidage latéraux, solidaires du bâti et aptes à coopérer avec des moyens de coulissement implantés sur les supports de coussin du premier et du second élément d'appui, ces moyens de coulissement procurant en outre un axe de pivotement dans la direction arrière-avant pour chaque support de coussin muni de ces moyens, de sorte que depuis la position initiale dans laquelle les supports de coussin du premier et du second élément d'appui sont alignés, une translation vers l'avant de l'élément d'assise entraîne une translation vers le bas et en suivant les moyens de guidage latéraux desdits moyens de coulissement, ce qui entraîne le pivotement relatif du premier élément d'appui par rapport à l'élément d'assise et du second élément d'appui par rapport au premier élément d'appui, l'angle entre les supports de coussin du premier et du second élément d'appui étant alors inférieur à 180° et l'articulation entre le premier et le second élément d'appui étant globalement déplacée du haut vers le bas et d'avant en arrière.
The present invention therefore aims to overcome these drawbacks by proposing a relaxation assembly comprising a fixed frame, which consists in particular of a generally vertical back, connected to a horizontal base and to side elements forming the cheeks of said assembly, themselves. linked to the base, which frame supports at least:
  • a substantially horizontal movable seat element, sliding parallel to the base along a rear-front axis,
  • a first movable support element, such as a backrest or a kidney block, inclined relative to the horizontal and articulated by its lower end to the rear end of the seat element so as to bow from top to bottom and back to front,
  • a second movable support element, such as a backrest or a headrest, inclined relative to the horizontal and articulated to the upper end of the first support element, each of said movable elements consisting of at least a cushion secured to a support, said assembly making it possible to pass, by means of a translation of the seat element, from an initial position where the user is in a sitting position to a relaxation position where the user is in semi-recumbent position and vice versa; this relaxation assembly is remarkable in that it is provided with lateral guide means, integral with the frame and adapted to cooperate with sliding means implanted on the cushion supports of the first and second bearing element, these sliding means further providing a pivot axis in the rear-front direction for each cushion support equipped with these means, so that from the initial position in which the cushion supports of the first and second bearing elements are aligned, a translation towards the front of the seat member results in a downward translation and following the lateral guide means of said sliding means, which causes the relative pivoting of the first support member relative to the seat member and the second support member relative to the first support member, angle between the cushion supports of the first and the second support element being then less than 180 ° and the articulation between the first and the second support element being generally displaced from the up down and back and forth.

On comprend bien qu'un tel ensemble est d'une cinématique relativement simple au regard des dispositifs antérieurs, permettant de garantir sa robustesse. En outre, le fonctionnement de l'ensemble de relaxation ne nécessite pas d'avoir un dégagement à l'arrière dudit ensemble, ce qui permet de positionner l'ensemble de relaxation directement contre une paroi. Avantageusement, ce système de coopération entre moyens de guidage et moyens de coulissement est adaptable à un grand nombre de modèles de siège, fauteuil, ou canapé d'ameublement ou de siège pour automobiles et en particulier aux banquettes arrières d'automobiles, sans modification importante de leur apparence ou de leur esthétique et ce, à un coût réduit.It is well understood that such an assembly is of a kinematics relatively simple compared to the previous devices, to ensure its robustness. In addition, the operation of the relaxation assembly does not require a clearance at the rear of said assembly, which allows to position the relaxation assembly directly against a wall. Advantageously, this system of cooperation between guide means and sliding means is adaptable to a large number of models of seat, chair, or sofa furniture or seat for cars and in particular to the rear seats of automobiles, without significant modification their appearance or aesthetics at a reduced cost.

D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre du mode d'exécution du dispositif de relaxation selon l'invention, donnés à titre d'exemples non limitatifs, en référence aux figures annexées sur lesquelles :

  • la figure 1 est une vue de côté et en coupe d'un premier mode de réalisation de l'ensemble de relaxation dans sa position initiale d'assise;

En référence à la figure 1, l'ensemble de relaxation 1, comporte un bâti fixe 2, qui est principalement constitué d'un dos 21 globalement vertical, connecté à une base horizontale 22 et à des éléments latéraux formant les joues 23, 24 (figure 3) dudit ensemble, elles-mêmes liées à la base 22.With reference to the figure 1 , the relaxation assembly 1 comprises a fixed frame 2, which consists mainly of a generally vertical back 21, connected to a horizontal base 22 and to side elements forming the cheeks 23, 24 ( figure 3 ) of said set, themselves linked to the base 22.

Le bâti 2 comprend également un élément avant 25 globalement vertical, connecté à la base 22 et reliant les joues 23, 24. Ce bâti 2 est classiquement constitué par un châssis tubulaire métallique habillé de tissu, par exemple. Bien entendu, les éléments du bâti pourront consister en des panneaux, par exemple en bois, sans sortir du cadre de l'invention.The frame 2 also comprises a generally vertical front element 25, connected to the base 22 and connecting the flanges 23, 24. This frame 2 is conventionally constituted by a metal tubular frame dressed with fabric, for example. Of course, the elements of the frame may consist of panels, for example wood, without departing from the scope of the invention.

Ce bâti 2 supporte un élément d'assise mobile 3 sensiblement horizontal, coulissant parallèlement à la base selon un axe arrière-avant. Cet élément d'assise 3 est constitué d'au moins un support d'assise 31, et d'un coussin d'assise 32. L'élément d'assise mobile 3 est monté sur une glissière horizontale 33 fixée sur un socle 34. La glissière horizontale 33 supportant l'élément d'assise 3 pourra être du type à billes, à friction ou tout autre type de glissière habituellement employé pour le coulissement de l'élément d'assise dans des dispositifs de relaxation.This frame 2 supports a substantially horizontal movable seat element 3, sliding parallel to the base along a rear-front axis. This seat element 3 consists of at least one seat support 31, and a seat cushion 32. The movable seat element 3 is mounted on a horizontal slide 33 fixed on a base 34. The horizontal slide 33 supporting the seat member 3 may be of the ball type, friction or any other type of slide usually used for sliding of the seat element in relaxation devices.

Un premier élément d'appui mobile 4, constituant avantageusement un dossier pour l'ensemble de relaxation 1, est articulé par son extrémité inférieure à l'extrémité arrière de l'élément d'assise 3. Ce dossier 4 est également constitué d'au moins un support de dossier 41 et d'un coussin de dossier 42. Un second élément d'appui mobile 5, constituant avantageusement un appuie-tête pour l'ensemble de relaxation 1, comportant au moins un support 51 et un coussin 52, est articulé à l'extrémité supérieure du dossier 4.A first movable support element 4, advantageously constituting a backrest for the relaxation assembly 1, is articulated by its lower end to the rear end of the seat element 3. This folder 4 also consists of less a back support 41 and a back cushion 42. A second movable support element 5, advantageously constituting a headrest for the relaxation assembly 1, comprising at least one support 51 and a cushion 52, is articulated at the upper end of the backrest 4.

Dans l'invention, l'ensemble de relaxation 1 comporte des glissières latérales rectilignes 6 fixes, solidarisées au bâti 2 et inclinées de haut en bas et d'arrière en avant. Ces glissières latérales rectilignes 6 coopèrent avec des roulettes 7 fixées sur les supports de l'appuie-tête 51 et du dossier 41 à proximité de l'articulation entre ces deux éléments mobiles 4, 5.In the invention, the relaxation assembly 1 comprises fixed rectilinear lateral slides 6, secured to the frame 2 and inclined from top to bottom and from back to front. These rectilinear lateral slides 6 cooperate with rollers 7 fixed on the supports of the headrest 51 and the backrest 41 near the articulation between these two movable elements 4, 5.

Selon une autre caractéristique de l'invention, les glissières latérales 6 mises en oeuvre sont rectilignes. De manière avantageuse, comme il est représenté sur les figures, on utilise une même glissière latérale rectiligne 6 sur chacun des côtés pour le guidage des roulettes 7 fixées au dossier 4 et à l'appuie-tête 5.According to another characteristic of the invention, the lateral slides 6 implemented are rectilinear. Advantageously, as shown in the figures, the same rectilinear lateral slideway 6 is used on each of the sides for guiding the rollers 7 fixed to the backrest 4 and to the headrest 5.

Dans la position initiale représentée sur la figure 1, les supports du dossier 41 et de l'appuie-tête 51 sont alignés.In the initial position shown on the figure 1 the supports of the backrest 41 and the headrest 51 are aligned.

En référence à la figure 2, sur laquelle l'ensemble 1 est en position de relaxation, l'angle entre les supports du dossier 41 et l'appuie-tête 51 est inférieur à 180°. Dans l'exemple, le plan du support de l'appuie-tête 51 est avantageusement proche de la verticale, permettant à l'utilisateur dudit ensemble d'avoir en position de relaxation le regard parallèle au sol, ce qui est particulièrement intéressant pour regarder la télévision, par exemple.With reference to the figure 2 , on which the assembly 1 is in the relaxation position, the angle between the supports of the backrest 41 and the headrest 51 is less than 180 °. In the example, the plane of the support of the headrest 51 is advantageously close to the vertical, allowing the user of said set to have in the relaxation position the gaze parallel to the ground, which is particularly interesting to watch television, for example.

Ce changement d'inclinaison relative entre le dossier 4 et l'appuie-tête 5 résulte d'une translation vers l'avant de l'élément d'assise 3 qui entraîne une translation vers le bas et en suivant les glissières latérales rectilignes 6 des roulettes 7. Le détail de la cinématique de l'ensemble 1 sera expliqué plus loin, en référence aux figures 4A et 4B.This change of relative inclination between the backrest 4 and the headrest 5 results from a forward translation of the seat element 3 which results in a downward translation and following the rectilinear lateral rails 6 of the 7. The details of the kinematics of Set 1 will be explained later, with reference to Figures 4A and 4B .

Selon une autre caractéristique de l'invention, les glissières latérales rectilignes 6 sont solidaires des joues 23, 24 de l'ensemble de relaxation 1, tel que représenté sur la figure 3A.According to another characteristic of the invention, the rectilinear lateral slides 6 are integral with the cheeks 23, 24 of the relaxation assembly 1, as shown in FIG. figure 3A .

En référence aux figures 3A et 3B et selon une autre caractéristique de l'invention, les roulettes 7 employées sont constituées d'un profilé métallique en forme de L, dont une première branche 71 est apte à être fixée sur les supports du dossier 41 et de l'appuie-tête 51, par des vis par exemple, et la seconde branche 72 supporte un élément de roulement 73 monté à rotation autour d'un axe 74 fixé perpendiculairement à la surface de ladite seconde branche.With reference to Figures 3A and 3B and according to another characteristic of the invention, the rollers 7 used consist of an L-shaped metal profile, a first branch 71 of which is capable of being fixed on the supports the backrest 41 and the headrest 51, by screws for example, and the second leg 72 supports a rolling member 73 rotatably mounted about an axis 74 fixed perpendicularly to the surface of said second leg.

Dans une autre variante non représentée, les moyens de coulissement 7 coopérant avec les glissières latérales rectilignes 6 pourront également consister en des tétons issus perpendiculairement des bords latéraux des supports du dossier 41 et de l'appuie-tête 51. Bien entendu, tout autre type de moyens de coulissement connu de l'Homme du Métier et applicable à l'ensemble de relaxation selon l'invention pourra être employé. A ce titre, on pourra envisager d'utiliser comme moyens de guidage 6 des rails fixes sur lesquels viendront coulisser des moyens de coulissement 7 solidaires des supports du dossier 41 et de l'appuie-tête 51, lesdits moyens de coulissement 7 consistant avantageusement en des profilés métalliques en forme de U.In another variant not shown, the sliding means 7 cooperating with the rectilinear side rails 6 may also consist of pins derived perpendicularly from the lateral edges of the supports of the backrest 41 and the headrest 51. Of course, any other type sliding means known to those skilled in the art and applicable to the relaxation assembly according to the invention may be used. In this respect, it will be possible to envisage using as guiding means 6 fixed rails on which sliding means 7 integral with the supports of the backrest 41 and of the head restraint 51 will slide, said sliding means 7 advantageously consisting of U-shaped metal profiles.

Selon une dernière caractéristique de l'invention, l'articulation rigide entre les éléments mobiles 3, 4, 5 est réalisée aux moyens de charnières 9.According to a last characteristic of the invention, the rigid articulation between the movable elements 3, 4, 5 is achieved by means of hinges 9.

L'ensemble de relaxation 1, tel que décrit en référence à la figure 1, pourra se décliner selon plusieurs variantes sans modifier fondamentalement son principe général de fonctionnement. En particulier, il sera envisageable d'utiliser comme premier élément d'appui mobile un cale-rein, disposé au niveau des reins de la personne assise, et comme second élément d'appui mobile un dossier pouvant, selon le cas, servir d'appuie-tête. Dans une autre variante possible, on pourra prévoir d'adjoindre un troisième élément d'appui mobile à la variante précédente, ledit élément étant articulé à son extrémité inférieure à l'extrémité supérieure du second élément et constituant un véritable appuie-tête.The relaxation set 1, as described with reference to the figure 1 , can be declined according to several variants without modifying fundamentally its general principle of operation. In particular, it will be conceivable to use as a first mobile support element a kidney-wedge, disposed at the level of the kidneys of the seated person, and as second movable support element a folder that can, depending on the case, serve as headrest. In another possible variant, provision may be made to add a third movable support element to the previous variant, said element being articulated at its lower end to the upper end of the second element and constituting a true headrest.

On décrira maintenant le fonctionnement de l'ensemble de relaxation représentée à la figure 1 en référence aux figures 4A et 4B.The operation of the relaxation assembly shown in FIG. figure 1 with reference to Figures 4A and 4B .

En position initiale, où l'utilisateur est en position assise, le dossier 4 et l'appuie-tête 5 sont alignés et l'élément d'assise 3 reculée en butée arrière. L'inclinaison des moyens de guidage, qui sont des glissières 6 dans l'exemple de réalisation donné, détermine l'inclinaison relative initiale du dossier 4 par rapport à l'élément d'assise 3. Le passage en position de relaxation, tel que représenté sur la figure 4B, découle d'une translation vers l'avant de l'élément d'assise 3. L'élément d'assise 3, le dossier 4 et l'appuie-tête 5 étant mécaniquement reliés, les moyens de coulissement 7 fixés au dossier 4 et à l'appuie-tête 5 vont subir une translation vers le bas selon l'axe défini par les moyens de guidage 6. L'articulation 9 entre l'appuie-tête 5 et le dossier 4 étant rigide, la contrainte de déplacement exercée va provoquer le pivotement de l'appuie-tête 5 par rapport au dossier 4, l'angle entre les supports de ces deux éléments devenant alors inférieur à 180°. Il en résulte également un déplacement global de l'articulation 9 disposée entre le dossier 4 et l'appuie-tête 5 du haut vers le bas et en arrière du plan d'alignement défini par les supports du dossier 41 et de l'appuie-tête 51 en position initiale.In the initial position, where the user is seated, the backrest 4 and the headrest 5 are aligned and the seat member 3 back to the rear stop. The inclination of the guide means, which are slides 6 in the given embodiment, determines the initial relative inclination of the backrest 4 with respect to the seat element 3. The transition to the relaxation position, such as represented on the Figure 4B derives from a translation towards the front of the seat element 3. The seat element 3, the backrest 4 and the headrest 5 being mechanically connected, the sliding means 7 fixed to the backrest 4 and the headrest 5 will be translated downwardly along the axis defined by the guide means 6. The articulation 9 between the headrest 5 and the backrest 4 being rigid, the displacement stress exerted will cause the pivoting of the headrest 5 relative to the backrest 4, the angle between the supports of these two elements then becoming less than 180 °. This also results in an overall displacement of the articulation 9 disposed between the backrest 4 and the headrest 5 from the top to the bottom and behind the alignment plane defined by the supports of the backrest 41 and the backrest. head 51 in the initial position.

On comprend bien que le positionnement des moyens de coulissement 7 à proximité de l'extrémité supérieure du dossier 4 et de l'extrémité inférieure de l'appuie-tête 5, de part et d'autre de l'articulation 9 entre ces deux éléments mobiles, va déterminer l'angle final d'inclinaison relative entre ces deux éléments. On comprend également que l'inclinaison relative entre le dossier 4 et l'élément d'assise 3, lorsque l'ensemble est en position de relaxation, est fonction de la course de l'élément d'assise 3 sur sa glissière horizontale 33. Bien entendu, l'Homme du Métier est à même d'effectuer les réglages permettant d'obtenir des valeurs d'inclinaison intermédiaires et finales déterminées à l'avance, prenant en compte la forme et l'épaisseur des coussins du dossier 42 et de l'appuie-tête 52.It is well understood that the positioning of the sliding means 7 near the upper end of the backrest 4 and the lower end of the headrest 5, on either side of the hinge 9 between these two elements mobile, will determine the final angle of relative inclination between these two elements. It is also understood that the relative inclination between the backrest 4 and the seat element 3, when the assembly is in the relaxation position, is a function of the travel of the seat element 3 on its horizontal slideway 33. Of course, the skilled person is able to make the adjustments to obtain intermediate and final inclination values determined in advance, taking into account the shape and thickness of the cushions of the folder 42 and the head restraint 52.

Dans les variantes précédemment décrites ainsi que dans toutes les variantes de l'invention pouvant être envisagées par l'Homme du métier, il va de soi qu'on pourra doter l'ensemble de relaxation de moyens de verrouillage afin de déterminer des positions intermédiaires entre la position assise et la position semi-allongée finale et doter ledit ensemble d'une motorisation, sans sortir du cadre de l'invention.In the variants previously described as well as in all the variants of the invention that can be envisaged by those skilled in the art, it goes without saying that the relaxation assembly may be provided with locking means in order to determine intermediate positions between the sitting position and the final semi-recumbent position and provide said assembly with a motor, without departing from the scope of the invention.

Enfin, il va de soi que l'ensemble de relaxation selon l'invention peut-être appliqué aux sièges d'intérieur mais aussi aux sièges d'avions, de trains ou d'automobiles et en particulier aux banquettes arrières à deux positions de confort, et que l'exemple de réalisation que l'on vient de décrire, n'est qu'une illustration particulière en aucun cas limitative des domaines de l'invention.Finally, it goes without saying that the relaxation assembly according to the invention can be applied to the interior seats but also to the seats of aircraft, trains or automobiles and in particular to the rear seats with two comfort positions. and that the embodiment which has just been described, is only a particular illustration in no way limiting the fields of the invention.
