Description

La présente invention concerne un fauteuil d'intérieur ou d'extérieur qui comprend, d'une part, une assise supportée par deux paires latérales de jambages s'étendant au-dessus de l'assise pour recevoir des accoudoirs et, d'autre part, un dossier articulé à sa base relativement à l'arrière de cette assise, ainsi qu'au-desssus relativement aux accoudoirs, lesquels sont déplaçables de l'avant vers l'arrière et inversement pour permettre le réglage de l'inclinaison du dossier.The present invention relates to an indoor or outdoor armchair which comprises, on the one hand, a seat supported by two lateral pairs of legs extending above the seat to receive armrests and, on the other hand , a backrest articulated at its base relative to the rear of this seat, as well as above relative to the armrests, which are movable from front to back and vice versa to allow the inclination of the backrest to be adjusted.

Pour que de tels fauteuils identiques entre eux soient empilables, il faut que leurs dossiers soient repliables sur leurs assises et que leurs accoudoirs soient escamotables.In order for such identical chairs to be stackable, their backrests must be foldable on their seats and their armrests must be retractable.

Le brevet français 2.593.686 décrit un fauteuil de ce type empilable. Dans ce fauteuil connu, les jambages de chaque paire convergent vers le haut et sont reliés rigidement par une traverse haute afin d'être empilables ; en outre, chaque accoudoir reposant sur la traverse conjuguée est fixé sur celle-ci de façon démontable et relié au dossier par un axe d'articulation situé au-dessus de l'accoudoir considéré à une distance de l'axe d'articulation du dossier sur l'assise telle, relativement à la distance de ce deuxième axe à l'extrémité antérieure de la traverse conjuguée précitée, que l'extrémité postérieure de l'accoudoir considéré puisse franchir l'extrémité antérieure de ladite traverse, pendant le repliement du dossier sur l'assise.French patent 2,593,686 describes a stackable chair of this type. In this known armchair, the legs of each pair converge upwards and are rigidly connected by a high crosspiece in order to be stackable; in addition, each armrest resting on the conjugate cross-member is fixed thereon in a removable manner and connected to the backrest by a hinge pin situated above the armrest considered at a distance from the hinge axis of the backrest on the seat such, relatively to the distance from this second axis to the anterior end of the above-mentioned conjugate cross-member, that the rear end of the armrest in question can cross the front end of said cross-member, during the folding of the backrest on the seat.

Par ailleurs, chaque accoudoir contient une crémaillère coopérant avec un doigt de la traverse conjuguée, doigt qui est prisonnier de l'accoudoir sur toute la course de réglage grâce à laquelle le dossier est réglable en inclinaison, cet accoudoir présentant une ouverture inférieure située à l'arrière de la crémaillère afin que le doigt puisse échapper lorsque ledit accoudoir est relevé pour replier le dossier.Furthermore, each armrest contains a rack cooperating with a finger of the conjugate crosspiece, finger which is trapped in the armrest over the entire adjustment stroke by means of which the backrest is adjustable in inclination, this armrest having a lower opening situated at the 'rear of the rack so that the finger can escape when said armrest is raised to fold the backrest.

Ainsi, avant gerbage, les accoudoirs sont déplacés vers l'avant en provoquant l'inclinaison du dossier, puis relevés et avancés pour échapper d'abord aux crémaillères et ensuite aux traverses des jambages du piètement, ce qui a pour effet de replier le dossier sur l'assise et concomitamment d'amener les accoudoirs en avant de celle-ci, les crosses de ces accoudoirs butant contre ladite assise.Thus, before stacking, the armrests are moved forward causing the backrest to tilt, then raised and advanced to escape first from the racks and then from the crosspieces of the legs of the legs, which has the effect of fold the backrest onto the seat and, at the same time, bring the armrests in front of it, the arms of these armrests abutting against said seat.

Un inconvénient de ce fauteuil connu est que son encombrement en position d'empilage est relativement important du fait que les accoudoirs dépassent largement le siège proprement dit à l'état replié siège qui comporte essentiellement le piètement, l'assise et le dossier rabattu sur celle-ci. Il en résulte que le taux de remplissage des camions ou autres véhicules est limité, ce qui accroît le coût du transport. Il en résulte également que le rangement d'une pile chez l'utilisateur nécessite plus de place.A disadvantage of this known chair is that its size in the stacking position is relatively large because the armrests extend far beyond the seat itself in the folded seat state which essentially comprises the base, the seat and the backrest folded over that -this. As a result, the filling rate of trucks or other vehicles is limited, which increases the cost of transport. It also follows that storing a battery at the user's place requires more space.

Un autre inconvénient de ce fauteuil connu est que les accoudoirs dépassant de la pile de sièges, deviennent fragiles et risquent d'être cassés.Another disadvantage of this known armchair is that the armrests protruding from the stack of seats, become fragile and risk being broken.

Un autre inconvénient encore de ce fauteuil connu est que la crosse qui permet de relever l'axe d'articulation de chaque accoudoir sur le dossier confère audit fauteuil un aspect inhabituel qui ne semble pas plaire à la clientèle.Yet another drawback of this known chair is that the stick which makes it possible to raise the articulation axis of each armrest on the backrest gives said chair an unusual appearance which does not seem to please customers.

Le brevet anglais 1 404 527 décrit également un fauteuil empilable dont le dossier peut être replié sur l'assise et les accoudoirs peuvent être escamotés.British patent 1,404,527 also describes a stackable armchair whose backrest can be folded over the seat and the armrests can be retracted.

Dans cet autre fauteuil connu, chaque accoudoir est relié au dossier par une sorte de cardan situé devant celui-ci. Un axe horizontal de ce cardan permet de relever l'accoudoir considéré tandis qu'un axe vertical dudit cardan permet de rabattre l'accoudoir relevé contre le devant du dossier. Dans cette dernière position des accoudoirs, il est possible de replier le dossier sur l'assise et ainsi de procéder à un gerbage.In this other known armchair, each armrest is connected to the backrest by a sort of gimbal located in front of it. A horizontal axis of this gimbal makes it possible to raise the armrest considered while a vertical axis of said gimbal makes it possible to fold the armrest raised against the front of the backrest. In this last position of the armrests, it is possible to fold the backrest on the seat and thus to stack.

L'avantage de cet autre fauteuil connu par rapport au précédent est que les accoudoirs ne dépassent pas du siège vers l'avant lorsque le dossier est replié sur l'assise. Le taux de remplissage d'un camion semble donc meilleur.The advantage of this other known chair compared to the previous one is that the armrests do not protrude from the seat forward when the backrest is folded over the seat. The filling rate of a truck therefore seems better.

Mais, le gerbage est doûteux et en tout cas instable et relativement encombrant, étant donné que les accoudoirs doivent prendre place entre l'assise et le dossier, lequel ne peut pas être complètement replié puisqu'il bute sur les accoudoirs formant entretoises.However, the stacking is dubious and in any case unstable and relatively bulky, since the armrests must take place between the seat and the backrest, which cannot be completely folded since it abuts on the armrests forming spacers.

La présente invention a pour but de remédier aux inconvénients de ces deux fauteuils connus, tout en conservant leurs avantages.The present invention aims to remedy the drawbacks of these two known armchairs, while retaining their advantages.

Elle vise également à ce que le fauteuil puisse être fabriqué en matière plastique avec un nombre très réduit de composants, donc de moules, et puisse être monté facilement et rapidement sans compétence particulière avec un nombre très faible d'axes de liaison. Cela conduit à ce que le prix de revient soit réduit et permette une commercialisation en grande surface.It also aims to ensure that the chair can be made of plastic with a very small number of components, therefore of molds, and can be mounted easily and quickly without special skill with a very small number of connecting axes. This leads to the cost price being reduced and allowing marketing in supermarkets.

Pour atteindre ce but, le fauteuil met en oeuvre la combinaison de moyens connue par les deux brevets précités. Dès lors, il comprend, d'une part, une assise supportée, de chaque côté, par une paire de jambages s'étendant au-dessus de l'assise et convergeant vers une traverse haute de liaison destinée à recevoir un accoudoir déplaçable longitudinalement et réglable au moyen d'un dispositif à crémaillère et doigt d'arrêt et, d'autre part, un dossier monté pivotant relativement à cette assise, le dossier étant en outre relié à chacun des deux accoudoirs par un dispositif d'articulation à deux axes s'étendant suivant sensiblement une ligne de plus grande pente de ce dossier, dite premier axe et respectivement un deuxième axe sensiblement perpendiculaire au premier et parallèle à l'axe de pivotement dudit dossier relativement à l'assise.To achieve this goal, the chair implements the combination of means known from the two aforementioned patents. Consequently, it comprises, on the one hand, a seat supported, on each side, by a pair of legs extending above the seat and converging towards a high cross-member intended to receive an armrest movable longitudinally and adjustable by means of a rack and pin device and, on the other hand, a pivotally mounted backrest relative to this seat, the backrest being further connected to each of the two armrests by a two-axis articulation device extending substantially along a line of greatest slope of this file, called the first axis and respectively a second axis substantially perpendicular to the first and parallel to the pivot axis of said file relative to the seat.

Conformément à l'invention, chaque dispositif d'articulation est disposé à l'arrière du dossier et en saillie sur une hauteur suffisante pour permettre le passage de l'accoudoir correspondant, par pivotement autour du premier axe, d'une position extérieure à une position intérieure relativement à un élément marginal du dossier qui porte le dispositif considéré, ces deux positions étant décalées de 180 degrés sensiblement et l'accoudoir précité pouvant pivoter dans chacune au moins desdites deux positions autour du deuxième axe pour, dans la position extérieure, s'enclencher sur la traverse conjuguée des jambages lorsque le dossier est relevé et, dans la position intérieure, s'appliquer à plat contre la face arrière du dossier jusqu'à ce que celui-ci repose sur l'assise.According to the invention, each articulation device is arranged at the rear of the backrest and protruding over a height sufficient to allow the passage of the corresponding armrest, by pivoting around the first axis, from a position external to a inner position relative to a marginal element of the backrest which carries the device in question, these two positions being offset by 180 degrees substantially and the aforementioned armrest being able to pivot in each at least of said two positions around the second axis, in the position outside, snap onto the conjugate cross member of the legs when the backrest is raised and, in the internal position, apply flat against the rear face of the backrest until it rests on the seat.

Suivant une forme de réalisation particulièrement avantageuse, pour constituer chaque dispositif d'articulation, l'accoudoir correspondant fait corps avec une tige faisant saillie latéralement dans une direction sensiblement perpendiculaire à son axe longitudinal et prolongée par une rotule montée tournante autour de son centre dans un palier de l'élément marginal précité du dossier, ce palier délimitant une fente qui s'étend, suivant le deuxième axe précité pour que la tige soit guidée et limite ainsi le pivotement de la rotule autour du premier axe, tandis que les chants dudit palier sont susceptibles de coopérer par butée avec le chant conjugué de l'accoudoir considéré pour limiter le pivotement de la rotule autour du deuxième axe.According to a particularly advantageous embodiment, to constitute each articulation device, the corresponding armrest forms a body with a rod projecting laterally in a direction substantially perpendicular to its longitudinal axis and extended by a ball joint rotatably mounted around its center in a bearing of the abovementioned marginal element of the backrest, this bearing delimiting a slot which extends, along the aforementioned second axis so that the rod is guided and thus limits the pivoting of the ball joint around the first axis, while the edges of said bearing are likely to cooperate by abutment with the conjugate edge of the armrest considered to limit the pivoting of the ball joint around the second axis.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Ainsi que cela ressort des figures 1 à 4, le fauteuil comporte une assise 1 venue de moulage en matière plastique avec deux paires latérales de jambages 2, les jambages d'une même paire convergeant vers le haut et s'étendant au-dessus de ladite assise jusqu'à une traverse 3 qui les relie. Ce siège partiel monolithique est conformé au moulage de telle façon que plusieurs sièges identiques puissent être gerbés constituer une pile (figure 4).As is apparent from Figures 1 to 4, the chair has a seat 1 molded from plastic with two lateral pairs of legs 2, the legs of the same pair converging upward and extending above said sitting up to a cross 3 which connects them. This monolithic partial seat is shaped so that several identical seats can be stacked to form a stack (Figure 4).

Le fauteuil comporte également un dossier 4 en matière plastique dont le démoulage s'effectue par l'arrière. Le dossier présente alors des montants latéraux 5 reliés par une traverse haute 6 et une traverse basse 7 entre lesquelles s'étendent des lamelles montantes 8 moins épaisses que lesdits éléments 5 à 7 qui sont profilés en U et ouverts en arrière.The armchair also has a plastic backrest 4, which is removed from the rear. The file then has lateral uprights 5 connected by an upper cross member 6 and a lower cross member 7 between which extend rising strips 8 thinner than said elements 5 to 7 which are U-shaped and open at the rear.

Les montants 5 du dossier 4 présentent en saillie, à leurs extrémités inférieures, des oreilles 9 disposées contre d'autres oreilles 10 formées en saillie au-dessus et en arrière des côtés de l'assise 1, ces oreilles 9 et 10 étant traversées par des axes alignés de pivotement 11.The uprights 5 of the backrest 4 have protruding, at their lower ends, ears 9 arranged against other ears 10 formed above and behind the sides of the seat 1, these ears 9 and 10 being crossed by aligned pivot axes 11.

Le fauteuil comporte enfin des accoudoirs 12 reposant, de façon réglable dans la direction antéro-postérieure, sur les traverses 3 des jambages 2 et reliés à l'arrière aux montants 5 du dossier par des dispositifs d'articulation 13.Finally, the armchair includes armrests 12 resting, adjustable in the anteroposterior direction, on the crosspieces 3 of the legs 2 and connected at the rear to the uprights 5 of the backrest by articulation devices 13.

Les dispositifs d'articulation 13 sont conçus pour que, comme le montrent les figures 5 à 7 :
- le dossier 4 puisse pivoter dans le sens de la flèche F1 (figure 5) afin de provoquer l'avancement complet des accoudoirs 12, avancement qui s'accompagne d'un léger pivotement desdits accoudoirs autour d'un axe sensiblement horizontal (flèche F2) grâce aux dispositifs 13 et qui en fin de course libère une crémaillère interne 14 de chaque accoudoir relativement à un doigt 15 de la traverse conjuguée 3 du piètement, ceci étant décrit dans ce qui suit en se référant à la figure 8.
- chaque accoudoir 12 qui s'étend normalement à plat sur la traverse conjuguée 3 du piètement suivant une direction antéro-postérieure, puisse pivoter suivant la flèche F2 (figure 5) autour de l'axe sensiblement horizontal précité pour s'élever légèrement et se dégager du doigt 15,
- l'accoudoir considéré 12 puisse ensuite pivoter à plat suivant la flèche F3 (figure 6) autour d'un axe sensiblement vertical grâce au dispositif 13, jusqu'à ce qu'il s'étende non plus vers l'avant, mais vers l'arrière dans une direction sensiblement parallèle à la traverse 3 du piètement,
- ledit accoudoir 12 puisse enfin pivoter à plat suivant la flèche F4 (figure 6) autour de l'axe sensiblement horizontal précité pour s'appliquer à plat sur les lamelles 8 du dossier 4 le long du montant 5 correspondant.
The articulation devices 13 are designed so that, as shown in Figures 5 to 7:
the backrest 4 can pivot in the direction of the arrow F1 (FIG. 5) in order to cause the complete advancement of the armrests 12, advancement which is accompanied by a slight pivoting of the said armrests around a substantially horizontal axis (arrow F2 ) thanks to the devices 13 and which at the end of the stroke releases an internal rack 14 of each armrest relative to a finger 15 of the conjugate cross member 3 of the base, this being described in the following with reference to FIG. 8.
each armrest 12 which normally extends flat on the conjugate cross member 3 of the base in an anteroposterior direction, can pivot according to the arrow F2 (FIG. 5) around the above-mentioned substantially horizontal axis to rise slightly and release finger 15,
- The armrest considered 12 can then pivot flat in the direction of arrow F3 (FIG. 6) around a substantially vertical axis thanks to the device 13, until it no longer extends forwards, but towards the rear in a direction substantially parallel to the cross-member 3 of the base,
- Said armrest 12 can finally pivot flat in the direction of arrow F4 (FIG. 6) around the above-mentioned substantially horizontal axis to apply flat on the slats 8 of the backrest 4 along the corresponding upright 5.

Dans cette dernière position illustrée par la figure 7, les accoudoirs 12 ne dépassent pas du dossier 4 et l'encombrement en épaisseur de cet ensemble 12,4 se trouve réduit au minimum. Dans ces conditions, lorsque le dossier 4 est replié sur l'assise 1 avec les accoudoirs 12 rabattus, ledit ensemble 12, 4 ne gêne pratiquement pas le gerbage (se reporter à la figure 4), gerbage qui peut, par conséquent, être très tassé c'est-à-dire avec un pas d'emboîtement très réduit.In this last position illustrated in FIG. 7, the armrests 12 do not protrude from the backrest 4 and the space requirement in thickness of this assembly 12.4 is reduced to a minimum. Under these conditions, when the backrest 4 is folded over the seat 1 with the armrests 12 folded down, said assembly 12, 4 practically does not interfere with stacking (see FIG. 4), stacking which can therefore be very packed, that is to say with a very small nesting pitch.

L'exposé qui précède montre que chaque dispositif d'articulation 13 doit comporter au moins deux axes de pivotement, l'un horizontal et l'autre vertical, et que chaque accoudoir 12 doit pouvoir être manoeuvré autour du montant 5 du dossier correspondant sur au moins 180 degrés en se trouvant, en position d'utilisation, du côté extérieur au montant vers l'avant, et en phase finale de repliement, du côté intérieur vers l'arrière puis vers l'avant. Chaque dispositif d'articulation 13 est alors disposé à l'arrière du montant correspondant 5 du dossier et en saillie sur une hauteur suffisante dépendant de la réalisation choisie.The foregoing description shows that each articulation device 13 must have at least two pivot axes, one horizontal and the other vertical, and that each armrest 12 must be able to be maneuvered around the upright 5 of the backrest corresponding over at least 180 degrees while in the position of use, on the outside of the upright, towards the front, and in the final folding phase, on the inside, towards the rear and then towards the front. Each articulation device 13 is then placed at the rear of the corresponding upright 5 of the backrest and protruding over a sufficient height depending on the embodiment chosen.

Deux formes de réalisation de chaque dispositif d'articulation 13 sont représentées sur les figures 9 à 12, mais avant de les décrire, il y a lieu de revenir sur la liaison règlable de chaque accoudoir 12 sur la traverse 3 correspondante du piètement.Two embodiments of each articulation device 13 are shown in FIGS. 9 to 12, but before describing them, it is necessary to return to the adjustable connection of each armrest 12 on the corresponding cross member 3 of the base.

L'accoudoir 12 considéré est profilé en U et présente en saillie interne sous son dessus des nervures transversales 16 régulièrement espacées et constituant les dents de la crémaillère 14 précitée. L'accoudoir délimite sous celle-ci un couloir 17 pour le passage du doigt 15 précité ; ce doigt fait saillie des deux côtés d'une patte 18 venue de moulage avec les traverses 3 du piètement; les flancs de l'accoudoir font corps avec deux rebords 19 délimitant entre eux une fente 20 d'accès au couloir ; lors du réglage de la position longitudinale de cet accoudoir et, par conséquent, de l'inclinaison du dossier, la patte 18 est disposée entre les rebords 19 et, l'accoudoir 12 étant soulevé pour que les parties extrêmes saillantes du doigt 15 reposent sur ces rebords, ledit doigt se trouve placé sous la crémaillère 14 dans le couloir 17.The armrest 12 considered is U-shaped and has an internal projection beneath its top of the transverse ribs 16 regularly spaced and constituting the teeth of the aforementioned rack 14. The armrest defines under it a corridor 17 for the passage of the aforementioned finger 15; this finger projects from the two sides of a tab 18 molded with the cross members 3 of the base; the sides of the armrest form a body with two flanges 19 delimiting between them a slot 20 for access to the corridor; during the adjustment of the longitudinal position of this armrest and, consequently, of the inclination of the backrest, the tab 18 is disposed between the flanges 19 and, the armrest 12 being raised so that the projecting end portions of the finger 15 rest on these edges, said finger is placed under the rack 14 in the corridor 17.

Dès lors, l'accoudoir est prisonnier du doigt 15, mais est libre de se déplacer en translation en étant guidé par les rebords 19. La position choisie étant atteinte, il suffit de laisser retomber l'accoudoir et le doigt 15 se met en prise avec la nervure 16 sélectionnée de la crémaillère 14.Therefore, the armrest is trapped in the finger 15, but is free to move in translation being guided by the flanges 19. The chosen position having been reached, it suffices to drop the armrest and the finger 15 engages with the selected rib 16 of the rack 14.

A proximité du dispositif d'articulation 13, les rebords 19 sont interrompus et les flancs de l'accoudoir 12 délimitent entre eux un passage 21 à travers lequel le doigt 15 peut passer. Ainsi, lors du repliement du fauteuil, les accoudoirs 12 sont tirés vers l'avant et en fin de course, sont soulevés pour échapper aux doigts 15 grâce aux passages 21. L'opération de repliement décrite dans ce qui précède en se référant aux figures 5 à 7 peut alors se dérouler.Near the articulation device 13, the edges 19 are interrupted and the sides of the armrest 12 delimit between them a passage 21 through which the finger 15 can pass. Thus, during the folding of the chair, the armrests 12 are pulled forward and at the end of the stroke, are raised to escape the fingers 15 thanks to the passages 21. The folding operation described in the foregoing with reference to FIGS. 5 to 7 can then take place.

Suivant une première forme de réalisation de chaque dispositif d'articulation 13 de réalisation illustrée par les figures 9 et 10, chaque accoudoir 12 est venu de moulage avec une tige 22 faisant saillie du côté intérieur près de son extrémité postérieure et s'étendant dans une direction sensiblement perpendiculaire à son axe longitudinal, la tige étant prolongée par une rotule 23.According to a first embodiment of each articulation device 13 of embodiment illustrated by FIGS. 9 and 10, each armrest 12 has come from molding with a rod 22 projecting from the interior side near its rear end and extending in a direction substantially perpendicular to its longitudinal axis, the rod being extended by a ball joint 23.

Le montant 5 correspondant du dossier est venu de moulage avec un corps de palier 24 dans lequel s'emboîte un couvercle 25 en matière plastique moulée. Dans le corps 24, fait saillie un tube 26 dont l'extrémité annulaire supérieure constitue un siège 27 pour la rotule 23 qui est maintenue appliquée contre ce siège par une portée 28 du couvercle 25. La rotule 23 est prisonnière du palier 24, 25 du fait que le couvercle 25 est fixé sur le corps 24 au moyen de vis 29 bloquées dans des manchons 30 de l'accoudoir. Ces vis sont disposées de part et d'autre d'une fente 31 ménagée dans le couvercle 25 pour permettre à la tige 22 de pivoter autour de l'axe longitudinal 32 du montant 5 du dossier de 180 degrés environ.The corresponding amount 5 of the back came from molding with a bearing body 24 in which fits a cover 25 of molded plastic. In the body 24, a tube 26 projects, the upper annular end of which constitutes a seat 27 for the ball joint 23 which is held pressed against this seat by a bearing 28 of the cover 25. The ball joint 23 is trapped in the bearing 24, 25 of the fact that the cover 25 is fixed to the body 24 by means of screws 29 locked in sleeves 30 of the armrest. These screws are arranged on either side of a slot 31 formed in the cover 25 to allow the rod 22 to pivot around the longitudinal axis 32 of the upright 5 of the backrest by about 180 degrees.

Grâce à ce pivotement, l'accoudoir peut occuper soit la position intérieure précitée représentée en trait plein sur la figure 9, soit la position extérieure représentée en trait mixte. Dans ces positions, le pivotement de la rotule 23 est limité à un pivotement autour d'un axe transversal 33 perpendiculaire à l'axe 32 et parallèle aux axes de pivotement 11 du dossier, étant donné que les chants 34 et 35 du palier 24, 25 coopèrent par butée et frottement avec le chant conjugué 36 de l'accoudoir 12. Ces pivotements autour de l'axe 33 permettent, lorsque l'accoudoir est en position extérieure (trait mixte), de l'amener sur la traverse correspondante 3 du piètement et, lorsque l'accoudoir est en position intérieure (trait plein) de l'appliquer contre la face arrière des lamelles 8 du dossier 4.Thanks to this pivoting, the armrest can occupy either the abovementioned interior position shown in solid lines in FIG. 9, or the exterior position shown in phantom. In these positions, the pivoting of the ball joint 23 is limited to a pivoting around a transverse axis 33 perpendicular to the axis 32 and parallel to the pivot axes 11 of the backrest, given that the edges 34 and 35 of the bearing 24, 25 cooperate by abutment and friction with the conjugate edge 36 of the armrest 12. These pivotings around the axis 33 allow, when the armrest is in the external position (dashed line), to bring it onto the corresponding cross member 3 of the base and, when the armrest is in the internal position (solid line) to apply it against the face back of the slats 8 of the backrest 4.

Suivant la deuxième forme de réalisation illustrée par les figures 11 et 12, chaque dispositif d'articulation 13 comporte un té monolithique 37 présentant un tourillon 38 s'étendant suivant l'axe transversal 33 précité et deux autres tourillons 39, 40 alignés suivant l'axe longitudinal 32 précité.According to the second embodiment illustrated in FIGS. 11 and 12, each articulation device 13 comprises a monolithic tee 37 having a pin 38 extending along the aforementioned transverse axis 33 and two other pins 39, 40 aligned along the longitudinal axis 32 above.

Le tourillon 38 est monté tournant dans un manchon 41 venu de moulage dans l'accoudoir 12 et il y est immobilisé en translation par une collerette 42 et un anneau démontable 43 connu sur le nom de circlip.The pin 38 is rotatably mounted in a sleeve 41 molded in the armrest 12 and there it is immobilized in translation by a flange 42 and a removable ring 43 known on the name of circlip.

Les tourillons 39, 40 sont montés tournants et immobilisés en translation dans un palier constitué, comme dans la première forme de réalisation, par un corps 24 venu de moulage avec le montant 5 correspondant du dossier 4 et par un couvercle 25 en matière plastique, le couvercle étant fixé sur le corps au moyen de vis 29 bloquées dans des manchons 30 du montant. Dans ce palier, le tube 26 présente, à son extrémité libre, un siège cylindrique 47 et le couvercle délimite, de part et d'autre de la fente 31 prévue pour le passage du tourillon 38, des portées semi-cylindriques 45, les tourillons 39, 40 étant guidés entre le siège 44 et les portées 45.The pins 39, 40 are mounted to rotate and immobilized in translation in a bearing constituted, as in the first embodiment, by a body 24 molded with the corresponding amount 5 of the backrest 4 and by a cover 25 made of plastic, the cover being fixed on the body by means of screws 29 blocked in sleeves 30 of the upright. In this bearing, the tube 26 has, at its free end, a cylindrical seat 47 and the cover delimits, on either side of the slot 31 provided for the passage of the pin 38, semi-cylindrical bearings 45, the pins 39, 40 being guided between the seat 44 and the bearing surfaces 45.
