Description

La présente invention concerne le montage d'un élément à inclinaison réglable sur un support, notamment d'un dossier de siège sur un piètement, ce montage comprenant deux organes de liaison symétriques entre le support et l'élément d'inclinaison réglable.The present invention relates to the mounting of an adjustable tilt element on a support, in particular a seat back on a base, this assembly comprising two symmetrical connecting members between the support and the adjustable tilt element.

Dans le domaine des sièges, et plus particulièrement des sièges pour enfants, il est intéressant de pouvoir régler l'inclinaison du dossier, de manière à obtenir au moins une position assise et une position couchée ou semi-couchée, et éventuellement aussi des positions intermédiaires. Dans ce but, et pour cette application particulière, on connaît déjà, par le brevet belge No 706358, un montage du genre rappelé ci-dessus. Ce document décrit, en fait, deux réalisations:

  • - Dans une première réalisation, les organes de liaison entre le piètement et le dossier sont de simples douilles ou manchons. Le changement d'inclinaison est obtenu en retournant le dossier, dont l'armature en U présente des coudes près de ses extrémités raccordées au piètement.
  • - Dans une seconde réalisation, les organes de liaison sont des douilles coudées, l'armature du dossier restant plane. Le changement d'inclinaison est obtenu en orientant les douilles coudées soit vers l'avant, soit vers l'arrière.
In the area of seats, and more particularly seats for children, it is advantageous to be able to adjust the inclination of the backrest, so as to obtain at least a seated position and a lying or semi-lying position, and possibly also intermediate positions. . To this end, and for this particular application is already known, from Belgian Patent No. 706,358, mounting the kind mentioned above. This document describes, in fact, two realizations:
  • - In a first embodiment, the connecting members between the base and the back are simple sockets or sleeves. The inclination change is obtained by turning over the backrest, whose U-shaped frame has elbows near its ends connected to the base.
  • - In a second embodiment, the connecting members are bent sockets, the frame of the backrest remaining flat. The inclination change is obtained by orienting the angled sockets either forwards or backwards.

Dans tous les cas, le changement de position du dossier nécessite un démontage suivi d'un remontage de ce dossier, ce qui complique l'utilisation pratique du dispositif. La présente invention vise à remédier à cet inconvénient, en fournissant un montage permettant le passage d'une première position à une seconde position par un mécanisme extrêmement simple non seulement dans sa réalisation, mais encore dans son utilisation.In all cases, the change of position of the backrest requires disassembly followed by reassembly of this backrest, which complicates the practical use of the device. The present invention aims to remedy this drawback, by providing an arrangement allowing the passage from a first position to a second position by an extremely simple mechanism not only in its production, but also in its use.

A cet effet, l'invention a pour objet un montage d'un élément à inclinaison réglable sur un support, notamment d'un dossier de siège sur un piètement, comprenant deux organes de liaison symétriques entre le support et l'élément d'inclinaison réglable, montage dans lequel chacun de ces deux organes de liaison est articulé, autour d'un premier axe, au support et est articulé, autour d'un second axe concourant avec le premier et faisant avec celui-ci un angle aigu a, à l'élément d'inclinaison réglable, cet élément et/ou le support étant déformables de telle sorte que, par pivotement des deux organes de liaison d'environ 180° autour de leurs axes d'articulation au support, l'élément d'inclinaison réglable puisse passer d'une première position à une seconde position, séparées angulairement de 2 a.To this end, the subject of the invention is the mounting of an adjustable tilt element on a support, in particular a seat back on a base, comprising two symmetrical connecting members between the support and the tilt element adjustable, mounting in which each of these two connecting members is articulated, around a first axis, to the support and is articulated, around a second axis competing with the first and making an acute angle with it, at the adjustable tilting element, this element and / or the support being deformable so that, by pivoting the two connecting members by about 180 ° around their axes of articulation to the support, the tilting element adjustable can go from a first position to a second position, angularly separated by 2 a.

On réalise ainsi un montage nécessitant un nombre de pièces et d'axes minimal, et offrant des positions extrêmes stables; la seule condition particulière à respecter dans sa réalisation est que l'une au moins des deux parties dites support et élément d'inclinaison réglable soit déformable, afin de permettre le retournement de 180° des deux organes de liaison, sans séparer le dossier du piètement. Cette condition est facilement réalisée dans le cas où l'élément d'inclinaison réglable est constitué par un dossier possédant une armature tubulaire en forme d'arceau.This produces an assembly requiring a minimum number of parts and axes, and offering stable extreme positions; the only particular condition to be observed in its realization is that at least one of the two parts called support and adjustable tilting element is deformable, in order to allow the 180 ° reversal of the two connecting members, without separating the back of the base . This condition is easily achieved in the case where the adjustable tilt element is constituted by a backrest having a tubular frame in the form of an arch.

Suivant une forme de réalisation de l'invention, les deux organes de liaison entre le support et l'élément d'inclinaison réglable sont constitués chacun par une pièce massive présentant deux alésages d'axes concourants, et débouchant respectivement sur deux faces opposées de ladite pièce massive, l'un de ces alésages recevant une partie en forme d'extrémité cylindrique ou tubulaire du support, tandis que l'autre alésage reçoit une partie en forme d'extrémité cylindrique ou tubulaire de l'élément d'inclinaison réglable, lesdites parties cylindriques étant montées pivotantes relativement à la pièce massive, suivant les axes des alésages précités. Il est à noter que, dans l'application aux sièges, cette disposition est utilisable sans aucun moyen supplémentaire de retenue axiale des parties cylindriques introduites dans les organes de liaison, ce qui conduit à une réalisation extrêmement simple. Pour faciliter le montage sans erreur de ces organes de liaison, on prévoit avantageusement que les deux alésages de chacun d'eux, de même que les parties correspondantes du support et de l'élément d'inclinaison réglable, ont des diamètres différents. Le choix d'organes de liaison monoblocs facilite aussi la manoeuvre pour le passage d'une position à l'autre et, dans ce but, les pièces considérées possèdent, de préférence, une partie latérale présentant une saillie destinée à leur préhension.According to one embodiment of the invention, the two connecting members between the support and the adjustable tilt element each consist of a solid part having two bores of concurrent axes, and opening respectively on two opposite faces of said massive part, one of these bores receiving a part in the form of a cylindrical or tubular end of the support, while the other bore receives a part in the form of a cylindrical or tubular end of the adjustable tilting element, said cylindrical parts being pivotally mounted relative to the solid part, along the axes of the aforementioned bores. It should be noted that, in the application to seats, this arrangement can be used without any additional means of axial retention of the cylindrical parts introduced into the connecting members, which leads to an extremely simple embodiment. To facilitate the error-free mounting of these connecting members, it is advantageously provided that the two bores of each of them, as well as the corresponding parts of the support and of the adjustable tilt element, have different diameters. The choice of one-piece connecting members also facilitates maneuvering for the passage from one position to another and, for this purpose, the parts considered preferably have a lateral part having a projection intended for their gripping.

Selon une caractéristique complémentaire, des moyens sont prévus pour bloquer angulairement les deux organes de liaison par rapport aux parties correspondantes du support et/ou de l'élément d'inclinaison réglable, de manière à pouvoir immobiliser cet élément dans des positions intermédiaires.According to an additional characteristic, means are provided for angularly blocking the two connecting members with respect to the corresponding parts of the support and / or of the adjustable tilt element, so as to be able to immobilize this element in intermediate positions.

L'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation de ce montage d'un élément à inclinaison réglablesur un support, dans le cas de son application à un dossier de siège réglable en inclinaison:

The invention will be better understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of this mounting of an element with adjustable inclination on a support, in the case of its application to an adjustable seat backrest:
  • fig. 1 is a perspective view of a portable child seat, the back of which is mounted in accordance with the invention;
  • fig. 2 is a sectional view of one of the two connecting members between the base and the back of this seat;

  • fig. 4 is a view similar to FIG. 3, but in the supine position;
  • fig. 5 is a partial front view of the sole frame of the child seat considered, illustrating the passage from one position to the other.

Comme le montrent les fig. 1, 3 et 4, l'invention est ici décrite dans son application particulière à un siège pour enfant, dont les parties principales sont un piètement 1, une assise 2 et un dossier 3 à inclinaison réglable.As shown in fig. 1, 3 and 4, the invention is described here in its particular application to a child seat, the main parts of which are a base 1, a seat 2 and a backrest 3 with adjustable inclination.

Le piètement 1 comprend une traverse arrière 4, reliant des parties latérales horizontales 5, cintrées à l'avant de manière à former deux extrémités 6 tournées vers le haut, mais inclinées par rapport à la verticale de telle manière qu'elles sont aussi tournées vers l'arrière.The base 1 comprises a rear crossmember 4, connecting horizontal lateral parts 5, curved at the front so as to form two ends 6 turned upwards, but inclined relative to the vertical so that they are also turned towards the back.

L'assise 2 comprend une armature 7 en forme d'étrier, dont les extrémités arrière sont articulées aux parties 6 du piètement 1, autour d'un axe orienté transversalement.The seat 2 comprises a frame 7 in the shape of a stirrup, the rear ends of which are articulated to the parts 6 of the base 1, around an axis oriented transversely.

Le dossier 3 comprend une armature tubulaire 8 en forme d'arceau, dont les deux extrémités inférieures 9 sont reliées aux extrémités supérieures 6 du piètement 1, par l'intermédiaire de deux pièces de liaison 10 symétriques.The backrest 3 comprises a tubular frame 8 in the form of a hoop, the two lower ends 9 of which are connected to the upper ends 6 of the base 1, by means of two symmetrical connecting pieces 10.

Dans l'exemple d'application représenté, les parties en tissu constituant l'assise 2 et le dossier 3, fixées aux armatures respectives 7 et 8, sont reliées entre elles et complétées par des sangles 11 pour le maintien de l'enfant. En outre, le dossier 3 est relié au piètement 1 par l'intermédiaire de deux courroies latérales 12, permettant de porter le siège.In the example of application shown, the fabric parts constituting the seat 2 and the backrest 3, fixed to the respective frames 7 and 8, are interconnected and completed by straps 11 for retaining the child. In addition, the backrest 3 is connected to the base 1 by means of two lateral belts 12, making it possible to carry the seat.

Les pièces de liaison 10 ont une structure bien visible sur la fig. 2. Elles sont massives, mais chacune d'elles présente deux alésages 13 et 14 qui débouchent respectivement sur deux faces opposées 15 et 16 de la pièce considérée. Les axes 17 et 18 de ces deux alésages 13 et 14 sont situés dans un même plan et sont concourants en un point 19; a désigne l'angle aigu formé par ces deux axes 17 et 18, cet angle pouvant être de l'ordre de 15°.The connecting pieces 10 have a structure clearly visible in FIG. 2. They are massive, but each of them has two bores 13 and 14 which open respectively on two opposite faces 15 and 16 of the part considered. The axes 17 and 18 of these two bores 13 and 14 are located in the same plane and are concurrent at a point 19; a denotes the acute angle formed by these two axes 17 and 18, this angle possibly being of the order of 15 °.

Dans l'exemple de réalisation représenté, l'alésage 13 de plus petit diamètre reçoit une extrémité supérieure 6 du piètement 1, et l'alésage 14 de plus grand diamètre reçoit l'extrémité inférieure 9 correspondante de l'armature 8 du dossier 3. Les diamètres différents des deux alésages 13 et 14, ainsi que des parties correspondantes 6 et 9 du piètement 1 et du dossier 3, évitent toute erreur de montage de la part de l'utilisateur.In the embodiment shown, the bore 13 of smaller diameter receives an upper end 6 of the base 1, and the bore 14 of larger diameter receives the corresponding lower end 9 of the frame 8 of the backrest 3. The different diameters of the two bores 13 and 14, as well as the corresponding parts 6 and 9 of the base 1 and of the backrest 3, avoid any assembly error on the part of the user.

Comme le montre la fig. 2, chaque pièce de liaison 10 possède encore, du côté de l'alésage 14, une partie latérale présentant une saillie 20 et une région incurvée concave 21, afin de faciliter la préhension de cette pièce 10.As shown in fig. 2, each connecting part 10 also has, on the side of the bore 14, a lateral part having a projection 20 and a concave curved region 21, in order to facilitate gripping of this part 10.

L'ajustement des parties 6 et 9 dans les deux pièces de liaison 10 est tel qu'il permette le pivotement de ces parties relativement auxdites pièces, suivant les axes 17 et 18; de plus, les divers éléments d'armature 5, 7 et 8 peuvent se déformer dans une certaine mesure, de sorte que le siège est utilisé de la manière suivante:

  • Dans une première position dite assise, représentée sur la fig. 3, les deux pièces de liaison 10 sont situées dans des plans verticaux parallèles, et possèdent une orientation telle que les extrémités inférieures 9 de l'arceau 8 soient moins inclinées par rapport à la verticale que les extrémités supérieures 6 du piètement 1. Le dossier 3 est ainsi placé dans une position relevée.
The adjustment of parts 6 and 9 in the two connecting pieces 10 is such that it allows these parts to pivot relative to said pieces, along axes 17 and 18; moreover, the various reinforcing elements 5, 7 and 8 can deform to a certain extent, so that the seat is used in the following manner:
  • In a first so-called sitting position, shown in FIG. 3, the two connecting pieces 10 are located in parallel vertical planes, and have an orientation such that the lower ends 9 of the arch 8 are less inclined relative to the vertical than the upper ends 6 of the base 1. The backrest 3 is thus placed in a raised position.

Dans une seconde position dite couchée, représentée sur la fig. 4, les deux pièces de liaison 10 sont encore situées dans des plans verticaux parallèles, mais possèdent une orientation inverse de la précédente, les saillies 20 étant tournées vers le bas et non plus vers le haut. Il en résulte que les extrémités inférieures 9 de l'arceau 8 sont plus inclinées par rapport à la verticale que les extrémités supérieures 6 du piètement 1. Le dossier 3 est ainsi placé dans une position abaissée.In a second so-called lying position, shown in FIG. 4, the two connecting pieces 10 are still situated in parallel vertical planes, but have an orientation opposite to the previous one, the projections 20 being turned downwards and no longer upwards. It follows that the lower ends 9 of the arch 8 are more inclined relative to the vertical than the upper ends 6 of the base 1. The backrest 3 is thus placed in a lowered position.

Cette position abaissée du dossier 3 est aussi indiquée en traits mixtes sur la fig. 3, laquelle montre que les deux positions sont séparées angulairement de 2 a (a conservant ici, bien entendu, la signification donnée précédemment et illustrée par la fig. 2).This lowered position of the backrest 3 is also indicated in dashed lines in FIG. 3, which shows that the two positions are angularly separated by 2 a (a retaining here, of course, the meaning given above and illustrated in FIG. 2).

Il en résulte aussi de ce qui précède que, pour le passage d'une position à l'autre, il convient de faire pivoter les deux pièces de liaison 10 d'environ 180° autour de leurs axes d'articulation aux extrémités supérieures 6 du piètement 1. On peut manoeuvrer ces deux pièces 10 dans des sens inverses, comme illustré par la fig. 5, pour le passage d'une position à l'autre. Si la forme des parties en tissu du siège le permet, on peut aussi manoeuvrer les deux pièces 10 dans le même sens, en les maintenant parallèles. La fig. 5 montre les déformations subies par les armatures lors du passage d'une position à l'autre.It also follows from the above that, for the passage from one position to another, it is necessary to rotate the two connecting pieces 10 by about 180 ° around their axes of articulation at the upper ends 6 of the base 1. It is possible to operate these two parts 10 in opposite directions, as illustrated in FIG. 5, for switching from one position to another. If the shape of the fabric parts of the seat allows it, the two parts 10 can also be maneuvered in the same direction, keeping them parallel. Fig. 5 shows the deformations undergone by the reinforcements when passing from one position to another.

On comprend que, dans les positions intermédiaires, telles que celle de la fig. 5, le dossier 3 occupe une inclinaison intermédiaire entre celles des positions assise et couchée. Des moyens peuvent être prévus, en complément, pour bloquer angulairement les deux pièces de liaison 10 par rapport aux extrémités correspondantes 6 et/ou 9, appartenant au piètement 1 et/ou au dossier 3, de manière à pouvoir immobiliser ce dossier 3 dans des positions intermédiaires.It is understood that, in the intermediate positions, such as that of FIG. 5, the backrest 3 occupies an intermediate inclination between those of the sitting and lying positions. Means can be provided, in addition, to angularly block the two connecting pieces 10 relative to the corresponding ends 6 and / or 9, belonging to the base 1 and / or to the backrest 3, so as to be able to immobilize this backrest 3 in intermediate positions.

L'invention, décrite ci-dessus dans son cas d'application à un siège pour enfant, peut être aussi appliquée aux sièges en général, ainsi qu'à d'autres domaines techniques dans lesquels se pose le problème du montage d'un élément à inclinaison réglable, par exemple pour des auvents.The invention, described above in its case of application to a child seat, can also be applied to seats in general, as well as to other technical fields in which the problem of mounting an element arises with adjustable inclination, for example for awnings.

Dans une variante, équivalant à la forme de réalisation décrite ci-dessus, les deux organes de liaison entre le support et l'élément à inclinaison réglable peuvent être constitués chacun, à la place des pièces massives décrites plus haut, par deux manchons d'axes concourants, réunis l'un à l'autre par exemple par soudure, et recevant des parties correspondantes du support et de l'élément d'inclinaison réglable.In a variant, equivalent to the embodiment described above, the two connecting members between the support and the element with adjustable inclination may each be constituted, in place of the solid parts described above, by two sleeves. concurrent axes, joined to each other for example by welding, and receiving corresponding parts of the support and of the adjustable tilt element.
