Description

L'invention concerne une crémone à têtière à deux tringles de verrouil­lage se déplaçant en sens contraire comprenant, dans un boîtier solidai­re de la têtière, un mécanisme comportant un fouillot présentant une partie saillante traversant une lumière dans la têtière et constituant un pêne battant et commandant directement la première tringle de verrouil­lage et indirectement par l'intermédiaire d'un élément inverseur la se­conde tringle de verrouillage, lesdites tringles de verrouillage étant disposées dans un même alignement et à plat contre la face interne de la têtière, l'extrémité de la première tringle de verrouillage étant dispo­sée le long de la face intérieure du boîtier tandis que l'extrémité de la seconde tringle de verrouillage est renvoyée contre le fond du boîtier.The invention relates to a cremone bolt with two locking rods moving in opposite directions, comprising, in a housing integral with the headrest, a mechanism comprising a nut having a protruding part passing through a light in the headrest and constituting a beating and controlling bolt the first locking rod directly and indirectly via a reversing element the second locking rod, said locking rods being arranged in the same alignment and flat against the internal face of the headrest, the end of the first locking rod being disposed along the inside of the housing while the end of the second locking rod is returned against the bottom of the housing.

On connaît déjà, par le document FR-A-2 116 775, une crémone à têtiè­re à deux tringles de verrouillage se déplaçant en sens contraire com­prenant, dans un boîtier solidaire de la têtière, un mécanisme comportant un fouillot commandant les deux tringles de verrouillage disposées dans un même alignement et à plat contre la face interne de la têtière, l'ex­trémité de la première tringle de verrouillage étant disposée le long de la face intérieure du boîtier tandis que l'extrémité de la seconde tringle de verrouillage est renvoyée contre le fond du boîtier.Document FR-A-2 116 775 already discloses a cremone bolt with a headrest with two locking rods moving in opposite directions, comprising, in a housing integral with the headrest, a mechanism comprising a nut controlling the two locking rods arranged in the same alignment and flat against the internal face of the headrest, the end of the first locking rod being disposed along the internal face of the housing while the end of the second locking rod is returned against the case back.

L'entaillage dans le profilé de l'ouvrant d'une fenêtre, porte-fenêtre ou analogue, pour loger le boîtier de cette crémone, est fonction de la largeur du boîtier qui, elle-même, est variable et dépend de la distance de laquelle l'axe du fouillot est éloigné de la face externe de la têtière.The notching in the profile of the opening of a window, French window or the like, for housing the casing of this cremone bolt, is a function of the width of the casing which itself is variable and depends on the distance from which the axis of the follower is distant from the external face of the headrest.

Pour chaque crémone à têtière comportant une distance différente entre l'axe du fouillot et la face externe de la têtière, il est nécessaire de prévoir un entaillage déterminé. De ce fait, les entaillages comportent des profondeurs différentes.For each headrest lever with a different distance between the axis of the follower and the external face of the headrest, it is necessary to provide a specific notch. As a result, the notches have different depths.

Ainsi, pour une crémone connue dont la distance entre l'axe du fouillot et la face externe de la têtière est de onze millimètres, il est nécessai­re, pour permettre l'insertion du boîtier dans le profilé, de prévoir un logement de vingt huit millimètres de profondeur, alors que pour une crémone dont la distance entre l'axe du fouillot et la face externe de la têtière est de dix sept millimètres, il est nécessaire de prévoir un logement de trente quatre millimètres de profondeur.Thus, for a known cremone bolt whose distance between the axis of the follower and the external face of the headrest is eleven millimeters, it is necessary, to allow the insertion of the housing in the profile, to provide a housing of twenty eight millimeters deep, while for a cremone bolt whose distance between the axis of the follower and the external face of the headrest is seventeen millimeters, it is necessary to provide a housing thirty four millimeters deep.

Ces variations de profondeur du logement obligent le fabricant de fe­nêtres, porte-fenêtres ou analogues, d'une part, de régler sa machine à entailler à la profondeur du logement nécessaire au boîtier, et, d'au­tre part, de prévoir un profilé plus large pour ne pas courir le risque d'affaiblir le montant par une profondeur de logement voisine de la lar­geur dudit profilé.These variations in the depth of the housing oblige the manufacturer of windows, French windows or the like, on the one hand, to adjust his notching machine to the depth of the housing necessary for the housing, and, on the other hand, to provide a more profiled profile. wide so as not to run the risk of weakening the upright by a depth of housing close to the width of said profile.

Par ailleurs, on connaît également, par le document FR-A-1 036 577, un mécanisme de crémone actionnant deux tringles de verrouillage se dépla­çant en sens contraire. Ce mécanisme comporte un boîtier dont la face avant présente une lumière pour le passage de la partie saillante d'un pêne tournant. Celui-ci est denté sur la plus grande partie de son pour­tour et ses dents engrènent sur la denture d'une crémaillère située dans un même plan que le pourtour denté du fouillot. Cette crémaillère com­porte une seconde denture actionnant une deuxième crémaillère par l'in­termédiaire d'une roue dentée. A ces deux crémaillères sont accrochées les deux tringles de verrouillage.Furthermore, document FR-A-1 036 577 also discloses a lever mechanism actuating two locking rods moving in opposite directions. This mechanism comprises a housing, the front face of which has a lumen for the passage of the projecting part of a rotary bolt. It is toothed over most of its periphery and its teeth mesh with the teeth of a rack located in the same plane as the toothed periphery of the follower. This rack has a second gear actuating a second rack by means of a toothed wheel. The two locking rods are attached to these two racks.

Toutefois, cette crémone nécessite un entaillage profond dans le chant de l'ouvrant du fait que l'interaction du pêne tournant avec la première crémaillère et l'interaction de cette dernière avec la seconde crémaillère sont situées dans un même plan et se font frontalement.However, this lever requires a deep notching in the edge of the opening because the interaction of the bolt with the first rack and the interaction of the latter with the second rack are located in the same plane and are done frontally.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, ré­sout le problème consistant à créer une crémone à têtière à deux trin­gles de verrouillage se déplaçant en sens contraire, comprenant dans un boîtier solidaire de la têtière, un mécanisme comportant un fouillot présentant une partie saillante traversant une lumière dans la têtière et constituant un pêne battant et commandant directement la première tringle de verrouillage et indirectement par l'intermédiaire d'un élément inverseur la seconde tringle de verrouillage, lesdites tringles de ver­rouillage étant disposées dans un même alignement et à plat contre la face interne de la têtière, l'extrémité de la première tringle de verrouil­ lage étant disposée le long de la face intérieure du boîtier tandis que l'extrémité de la seconde tringle de verrouillage est renvoyée contre le fond du boîtier, et dont la première tringle de verrouillage comporte une extrémité chevauchant latéralement le corps du fouillot et dont la seconde tringle de verrouillage comporte une extrémité chevauchant bi­latéralement le corps du fouillot.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, solves the problem of creating a cremone bolt with two locking rods moving in opposite directions, comprising in a housing integral with the headrest, a mechanism comprising a nut having a protruding part passing through a lumen in the headrest and constituting a beating bolt and directly controlling the first locking rod and indirectly via a reversing element the second locking rod, said locking rods being arranged in the same alignment and flat against the internal face of the headrest, the end of the first lock rod lage being arranged along the inner face of the housing while the end of the second locking rod is returned against the bottom of the housing, and whose first locking rod has one end laterally overlapping the body of the follower and the second locking rod has one end bilaterally overlapping the body of the follower.

Par ailleurs, selon l'invention, la commande directe de l'extrémité de la première tringle de verrouillage par le fouillot se conçoit économiquement dès lors que le fouillot comporte un secteur denté, faisant saillie latéra­lement par rapport à son corps, engrenant dans un secteur denté de l'extrémité de la première tringle de verrouillage.Furthermore, according to the invention, the direct control of the end of the first locking rod by the follower is economically conceivable when the follower has a toothed sector, projecting laterally relative to its body, meshing in a sector toothed from the end of the first locking rod.

Une conception particulière de l'invention, évitant un forgeage de l'ex­trémité de la première tringle de verrouillage lorsque le fouillot compor­te un pêne battant, prévoit que la première tringle de verrouillage com­porte une pièce de liaison pourvue du téton engrenant dans la lumière réalisée dans le corps du fouillot.A particular design of the invention, avoiding forging the end of the first locking rod when the follower comprises a beating bolt, provides that the first locking rod comprises a connecting piece provided with the stud engaging in the light produced in the body of the follower.

Pour réduire davantage la largeur du boîtier, l'invention prévoit que l'extrémité de la seconde tringle de verrouillage renvoyée contre le fond du boîtier comporte, en regard du fouillot, une lumière de dégagement.To further reduce the width of the housing, the invention provides that the end of the second locking rod returned against the bottom of the housing includes, facing the follower, a release light.

Cette lumière permet, en effet, au corps du fouillot d'empiéter dans le volume occupé par la seconde tringle de verrouillage. Mais, elle permet aussi une réalisation particulière de l'invention selon laquelle le démarra­ge du mouvement de déverrouillage de la crémone est facilité par une disposition de l'invention prévoyant que le corps du fouillot comporte une courbure d'attaque agissant contre une face d'appui de la lumière de dégagement de l'extrémité de la seconde tringle de verrouillage.This light allows the body of the follower to encroach on the volume occupied by the second locking rod. However, it also allows a particular embodiment of the invention according to which the start of the unlocking movement of the lever is facilitated by a provision of the invention providing that the body of the follower has an attack curvature acting against a face of support of the clearance light at the end of the second locking rod.

En effet, cette disposition de l'invention permet une action directe con­juguée du fouillot sur les extrémités des deux tringles de verrouillage à un moment où l'effort à transmettre par le mécanisme de la crémone aux tringles de verrouillage est à son apogée, c'est-à-dire au moment où il s'agit d'amorcer le déverrouillage de la crémone.Indeed, this arrangement of the invention allows a direct combined action of the nut on the ends of the two locking rods at a time when the force to be transmitted by the mechanism of the lever to the locking rods is at its peak, c ' that is to say when it comes to initiating the unlocking of the lever.

Un des avantages obtenus grâce à cette invention consiste essentielle­ ment en ce que la profondeur de l'entaillage du logement pour le boî­tier est ramenée à la profondeur la plus faible, notamment pour les cré­mones comportant une distance maxima entre l'axe du fouillot et la face externe de la têtière. De ce fait, la profondeur de l'entaillage du loge­ment pour le boîtier est identique malgré différentes distances entre l'axe du fouillot et la face externe de la têtière.One of the advantages obtained thanks to this invention consists essential ment in that the depth of the notching of the housing for the housing is reduced to the smallest depth, in particular for the cremone bolts comprising a maximum distance between the axis of the follower and the external face of the headrest. Therefore, the depth of the notching of the housing for the housing is identical despite different distances between the axis of the follower and the outer face of the headrest.

Un autre avantage obtenu grâce à cette invention consiste en ce que, du fait que l'action entre le fouillot et le secteur denté de l'extrémité de la première tringle de verrouillage se fait par l'intermédiaire de mo­yens disposés latéralement par rapport au corps du fouillot, on peut ré­duire une première fois la largeur du boîtier et que, du fait que l'ex­trémité de la seconde tringle de verrouillage comporte une rainure dans laquelle s'engage le fouillot, il est possible de rapprocher cette seconde tringle de verrouillage de la têtière et de diminuer une seconde fois la largeur du boîtier. De ce fait, il est également possible de réduire la profondeur de l'entaille pratiquée dans le chant de l'ouvrant.Another advantage obtained thanks to this invention consists in that, because the action between the follower and the toothed sector of the end of the first locking rod takes place by means arranged laterally relative to the body of the follower, the width of the housing can be reduced for the first time and, since the end of the second locking rod has a groove in which the follower engages, it is possible to bring this second locking rod together. the headrest and decrease the width of the housing a second time. Therefore, it is also possible to reduce the depth of the notch made in the edge of the opening.

On se réfère aux figures 1 à 3.We refer to Figures 1 to 3.

La crémone 1 comporte un boîtier 2 dont l'avant 3 est solidaire de la face interne 4 d'une têtière 5, cette face interne 4 servant également de face intérieure du boîtier 2. Cette face interne 4, dans le sens lon­gitudinal, s'étend de part et d'autre dudit boîtier 2.The cremone bolt 1 comprises a housing 2, the front 3 of which is integral with the internal face 4 of a faceplate 5, this internal face 4 also serving as the internal face of the housing 2. This internal face 4, in the longitudinal direction, s' extends on either side of said housing 2.

Le boîtier renferme un mécanisme comportant un fouillot 6. Ce fouillot 6 commande deux tringles de verrouillage 7, 8 se déplaçant en sens contraire. Les deux tringles de verrouillage 7, 8 sont disposées dans un même alignement et à plat contre la face interne 4 de la têtière 5. L'extrémité 9 de la première tringle de verrouillage 7 est disposée le long de la face intérieure du boîtier 2 alors que l'extrémité 10, reliée par un renvoi 11 à la seconde tringle de verrouillage 8, et faisant par­tie intégrante de cette dernière, se déplace le long du fond 12 du boî­tier 2.The housing contains a mechanism comprising a follower 6. This follower 6 controls two locking rods 7, 8 moving in opposite directions. The two locking rods 7, 8 are arranged in the same alignment and flat against the internal face 4 of the headrest 5. The end 9 of the first locking rod 7 is arranged along the internal face of the housing 2 then that the end 10, connected by a reference 11 to the second locking rod 8, and forming an integral part of the latter, moves along the bottom 12 of the housing 2.

Le fouillot 6 commande directement l'extrémité 9 de la première tringle de verrouillage 7 par l'intermédiaire d'une liaison 13 disposée perpendi­culairement au corps 14 du fouillot 6. Pour obtenir le résultat recherché, l'extrémité 9 de la première tringle de verrouillage 7 chevauche latéra­lement ledit corps 14 du fouillot 6.The follower 6 directly controls the end 9 of the first locking rod 7 by means of a connection 13 arranged perpendicular to the body 14 of the follower 6. To obtain the desired result, the end 9 of the first locking rod 7 laterally overlaps said body 14 of the follower 6.

L'extrémité 9 de la première tringle de verrouillage 7 est pourvue d'une denture 15 coopérant avec un élément inverseur 16. Celui-ci est avanta­geusement un pignon denté pivotant autour d'un axe 17 solidaire du boî­tier 2. L'élément inverseur 16 coopère avec une denture 18 réalisée dans l'extrémité 10 de la seconde tringle de verrouillage 8. Par cet élément inverseur 16, le fouillot 6 commande indirectement la seconde tringle de verrouillage 8.The end 9 of the first locking rod 7 is provided with a toothing 15 cooperating with a reversing element 16. The latter is advantageously a toothed pinion pivoting about an axis 17 integral with the housing 2. The reversing element 16 cooperates with a toothing 18 produced in the end 10 of the second locking rod 8. By this reversing element 16, the follower 6 indirectly controls the second locking rod 8.

Selon un premier mode de réalisation, la liaison 13 comporte sur la trin­gle 7 de verrouillage de la crémone 1 un secteur denté 15ʹ s'engrenant avec une denture 16ʹ réalisée dans le corps 14 du fouillot 6.According to a first embodiment, the connection 13 comprises on the rod 7 for locking the cremone bolt 1 a toothed sector 15ʹ meshing with a toothing 16ʹ produced in the body 14 of the follower 6.

Selon un second mode de réalisation, la liaison 13 est constituée d'une lumière 20 et d'un téton 21 se déplaçant dans cette lumière 20.According to a second embodiment, the link 13 consists of a lumen 20 and a stud 21 moving in this lumen 20.

Avantageusement, l'extrémité 9 de la première tringle de verrouillage 7 présente la lumière 20 alors que le téton 21 fait saillie latéralement par rapport au corps 14 du fouillot 6.Advantageously, the end 9 of the first locking rod 7 has the lumen 20 while the stud 21 protrudes laterally relative to the body 14 of the follower 6.

Selon un autre mode de réalisation, le téton 21 est solidaire de l'extré­mité 9 de la première tringle de verrouillage 7 alors que la lumière 20 est réalisée dans le corps 14 du fouillot 6.According to another embodiment, the stud 21 is integral with the end 9 of the first locking rod 7 while the opening 20 is produced in the body 14 of the follower 6.

Le guidage de l'extrémité 9 de la première tringle de verrouillage 7 est assuré du fait que cette extrémité 9 comporte à sa face arrière 22 au moins un chant de guidage 23 prenant appui contre l'arbre 24 du fouil­lot 6.The guidance of the end 9 of the first locking rod 7 is ensured by the fact that this end 9 has at its rear face 22 at least one guide edge 23 bearing against the shaft 24 of the follower 6.

Selon un autre mode d'exécution, le corps 14 du fouillot 6 comporte une partie saillante 26. Celle-ci traverse une lumière 27 réalisée dans la tê­tière 5. De ce fait, cette partie saillante 26 peut constituer un pêne bat­tant, donc un point de verrouillage situé à hauteur de la poignée.According to another embodiment, the body 14 of the follower 6 has a projecting part 26. The latter passes through a lumen 27 made in the headrest 5. Therefore, this projecting part 26 can constitute a beating bolt, therefore a point lock located at the handle.

Par ailleurs, la première tringle de verrouillage 7 comporte avantageuse­ment une pièce de liaison 28 pourvue du téton 21 engrenant dans la lumière 20 réalisée dans le corps 14 du fouillot 6. Cette pièce de liaison 28 est disposée perpendiculairement par rapport à la face arrière 22 de l'extrémité 9 de la première tringle de verrouillage 7. Cette pièce de liaison 28 présente également le chant de guidage 23 prenant appui con­tre l'arbre 24 du fouillot 6. On pratique dans l'une des extrémités 29 de la pièce de liaison 28 une découpe 30 dans laquelle s'insère un doigt de commande 31 situé à proximité du chant extrême 25 de l'extrémité 9 de la première tringle de verrouillage 7.Furthermore, the first locking rod 7 advantageously comprises a connecting piece 28 provided with the stud 21 meshing in the lumen 20 produced in the body 14 of the follower 6. This connecting piece 28 is arranged perpendicularly to the rear face 22 of the end 9 of the first locking rod 7. This connecting piece 28 also has the guide edge 23 bearing against the shaft 24 of the follower 6. One practices in one of the ends 29 of the connecting piece 28 a cutout 30 into which is inserted a control finger 31 located near the end edge 25 of the end 9 of the first locking rod 7.

Pour diminuer la largeur du boîtier 2, l'extrémité 10 de la seconde trin­gle de verrouillage 8 comporte, en regard du fouillot 6, une lumière de dégagement 32. Cette lumière de dégagement 32 permet au corps 14 du fouillot 6 d'empiéter dans le volume occupé par la seconde tringle de verrouillage 8. Lorsque la crémone 1 est en position de verrouillage, un chant du corps 14 du fouillot 6 constitue une courbure d'attaque (19) coopérant avec une face d'appui 33 de la lumière de dégagement 32. De ce fait, on facilite le démarrage du mouvement de déverrouillage de la crémone 1. Ainsi, la commande directe de la première tringle de verrouillage 7 est assurée par la pièce de liaison 28 coulissant entre une des faces du corps 14 du fouillot 6 et une des faces internes des parois latérales du boîtier 2. Cette pièce de liaison 28 est pependiculai­re à la face interne de la première tringle de verrouillage 7 et coopère, d'une part, avec cette dernière, par l'intermédiaire du doigt de comman­de 31 situé à proximité du chant extrême 25 de l'extrémité 9 de la pre­mière tringle de verrouillage 7 et s'insérant dans une découpe 30 réali­sée dans la pièce de liaison 28 et, d'autre part, avec le fouillot 6 par l'intermédiaire du téton 21 coulissant dans la lumière 20 réalisée dans le corps 14 du fouillot 6.To reduce the width of the housing 2, the end 10 of the second locking rod 8 comprises, facing the follower 6, a clearance light 32. This clearance light 32 allows the body 14 of the follower 6 to encroach on the volume occupied by the second locking rod 8. When the cremone bolt 1 is in the locking position, a song of the body 14 of the follower 6 constitutes an attack curvature (19) cooperating with a bearing face 33 of the release light 32. Therefore, it facilitates the start of the unlocking movement of the lever 1. Thus, the direct control of the first rod locking 7 is ensured by the connecting piece 28 sliding between one of the faces of the body 14 of the follower 6 and one of the internal faces of the side walls of the housing 2. This connecting piece 28 is pependicular to the internal face of the first locking rod 7 and cooperates, on the one hand, with the latter, via the control finger 31 located near the end edge 25 of the end 9 of the first locking rod 7 and fitting into a cutout 30 made in the connecting piece 28 and, on the other hand, with the follower 6 by means of the stud 21 sliding in the slot 20 produced in the body 14 of the follower 6.

Cependant, pour obtenir une bonne qualité du fonctionnement du méca­nisme logé dans le boîtier 2 de la crémone, il est nécessaire d'assurer, lors du montage en usine de la crémone, un bon maintien de la première tringle de verrouillage 7 sur la face interne 4 de la têtière 5. Ce main­tien est réalisé par l'intermédiaire d'un rivet traversant une lumière pra­tiquée dans la première tringle de verrouillage 7 et la coopération du ri­vet et de la lumière assure le guidage de cette dernière. Cette disposi­tion entraîne une augmentation du coût de revient de la crémone mais permet, par contre, de réduire le jeu de l'extrémité de la première trin­gle de verrouillage 7 dans le boîtier 2.However, to obtain a good quality of operation of the mechanism housed in the housing 2 of the cremone bolt, it is necessary to ensure, during the factory mounting of the cremone bolt, good maintenance of the first locking rod 7 on the internal face 4 of the headrest 5. This holding is carried out by means of a rivet passing through a lumen made in the first locking rod 7 and the cooperation of the rivet and the lumen guides the latter. This arrangement leads to an increase in the cost price of the cremone bolt but, on the other hand, makes it possible to reduce the play of the end of the first locking rod 7 in the housing 2.

Toutefois, la pratique a permis de constater que la crémone à têtière présente un certain nombre d'inconvénients. En premier lieu, il s'est avéré que la pièce de liaison 28 présente une certaine fragilité, ce qui diminue la fiabilité de la crémone. Par ailleurs, cette pièce de liaison 28 limite la course de la première tringle de verrouillage 7 et, par voie de conséquence, la course de la seconde tringle de verrouillage 8. En ef­fet, il s'est avéré que la course n'est plus que de seize millimètres alors que, selon les normes traditionnelles, cette course devrait être de dix huit millimètres. Finalement, l'unique guidage de la pièce de liaison 28 contre l'arbre 24 du fouillot 6 lors de la mise en position d'ouverture de la crémone ou contre le rivet d'assemblage des deux parois latérales du boîtier 2 n'assure pas un bon maintien des différents éléments mis en présence. Il peut en résulter un jeu trop important risquant de nuire au bon fonctionnement de la crémone.However, practice has shown that the headrest lever has a number of drawbacks. Firstly, it turned out that the connecting piece 28 has a certain brittleness, which reduces the reliability of the cremone bolt. Furthermore, this connecting piece 28 limits the stroke of the first locking rod 7 and, consequently, the stroke of the second locking rod 8. In fact, it has been found that the stroke is no longer than sixteen millimeters when, according to traditional standards, this stroke should be eighteen millimeters. Finally, the sole guide of the connecting piece 28 against the shaft 24 of the follower 6 when the cremone bolt is placed in the open position or against the assembly rivet of the two side walls of the housing 2 does not provide good maintenance of the various elements brought together. This may result in too much play, which may affect the proper functioning of the cremone bolt.

Il n'est pas possible de pallier à ces inconvénients en utilisant un mé­ tal plus résistant aux efforts demandés lors du fonctionnement car, non seulement l'utilisation d'un métal spécial entraînerait une augmenta­tion du coût de revient de la crémone mais, nécessiterait également un outillage adapté.It is not possible to overcome these drawbacks by using a mé tal more resistant to the forces required during operation because, not only the use of a special metal would lead to an increase in the cost price of the cremone bolt, but would also require suitable tools.

L'invention a également pour but de concevoir une crémone à têtière à deux tringles de verrouillage se déplaçant en sens contraire d'une cour­se au moins égale à la course déterminée par les normes traditionnelles, tout en permettant d'augmenter la résistance de la pièce de liaison aux efforts demandés et d'assurer un bon maintien de toutes les pièces du mécanisme logées dans le boîtier.The invention also aims to design a cremone bolt with two locking rods moving in the opposite direction of a stroke at least equal to the stroke determined by traditional standards, while increasing the resistance of the part of connection to the efforts required and to ensure good maintenance of all the parts of the mechanism housed in the housing.

Il est donc souhaitable de supprimer toute torsion de la pièce de liaison 28 à l'emplacement de l'interaction de cette dernière avec le fouillot 6 tout en améliorant le fonctionnement du mécanisme logé dans le boîtier 2 en assurant un bon maintien de la première tringle de verrouillage 7 con­tre la face interne 4 de la têtière 5 de la pièce de liaison 28 et du fouil­lot 6.It is therefore desirable to suppress any twisting of the connecting piece 28 at the site where the latter interacts with the follower 6 while improving the operation of the mechanism housed in the housing 2 while ensuring good retention of the first rod. locking 7 against the internal face 4 of the headrest 5 of the connecting piece 28 and of the follower 6.

On se réfère aux figures 4 et 5.We refer to Figures 4 and 5.

La pièce de liaison est une fourche 34 composée de deux branches 35, 36 parallèles aux faces 37, 38 du corps 14 du fouillot 6.The connecting piece is a fork 34 composed of two branches 35, 36 parallel to the faces 37, 38 of the body 14 of the follower 6.

Selon un premier mode de réalisation, le plan médian de la fourche 34 est situé dans un même alignement que le plan médian 39 du fouillot 6.According to a first embodiment, the median plane of the fork 34 is located in the same alignment as the median plane 39 of the follower 6.

Selon un second mode de réalisation préférentiel, le plan médian de la fourche 34 est désaxé par rapport au plan médian 39 du fouillot 6. Se­lon ce mode de réalisation, la fourche 34 comporte une branche 35 cou­lissant le long de la face interne 40 de l'une des parois latérales 41 du boîtier 2 et une branche 36 composée de deux ailes 42, 43 reliées par une cambrure 44. L'une des ailes 42 est solidaire de la branche 35 alors que l'autre aile 43 est disposée entre la face 37 du fouillot 6 et la face interne 45 de l'autre paroi latérale 46 du boîtier 2.According to a second preferred embodiment, the median plane of the fork 34 is offset from the median plane 39 of the follower 6. According to this embodiment, the fork 34 comprises a branch 35 sliding along the internal face 40 of the 'one of the side walls 41 of the housing 2 and a branch 36 composed of two wings 42, 43 connected by a camber 44. One of the wings 42 is integral with the branch 35 while the other wing 43 is disposed between the face 37 of the follower 6 and the internal face 45 of the other side wall 46 of the housing 2.

Selon un mode d'exécution, les deux branches 35, 36 forment une seule pièce.According to one embodiment, the two branches 35, 36 form a single piece.

Selon un autre mode d'exécution, les deux branches 35, 36 sont deux pièces distinctes reliées entre-elles par un moyen d'assemblage. Even­tuellement, les deux branches 35, 36 sont séparables et le moyen d'as­semblage est formé soit par un axe 47 reliant la branche 35 de la four­che 34 à l'aile 42 de la branche 36 de la fourche 34, soit par au moins un repli repoussé ou découpé dans le corps de la branche 35 ou de l'ai­le 42 et s'engrenant dans au moins une lumière réalisée dans le corps de la branche 35 ou de l'aile 42. Ainsi, en cas de détérioration, il est possible de remplacer l'une ou l'autre des deux branches 35, 36.According to another embodiment, the two branches 35, 36 are two separate parts interconnected by an assembly means. Optionally, the two branches 35, 36 are separable and the assembly means is formed either by an axis 47 connecting the branch 35 of the fork 34 to the wing 42 of the branch 36 of the fork 34, or by at least one folded back or cut in the body of the branch 35 or the wing 42 and meshing in at least one lumen made in the body of the branch 35 or the wing 42. Thus, in the event of deterioration, it is it is possible to replace either of the two branches 35, 36.

Le téton 21 peut être solidaire de la face interne 48 de la branche 35 ou de la face interne 49 de l'aile 43 de la branche 36. Avantageusement, ce téton 21 peut être remplacé par un axe dont les extrémités 50, 51 sont engagées dans des orifices 52, 53 réalisés respectivement dans la branche 35 et dans l'aile 43 de la branche 36.The stud 21 can be integral with the internal face 48 of the branch 35 or the internal face 49 of the wing 43 of the branch 36. Advantageously, this stud 21 can be replaced by an axis whose ends 50, 51 are engaged in orifices 52, 53 made respectively in branch 35 and in wing 43 of branch 36.

Soit l'une des branches 35, 36, soit les deux branches 35, 36 de la fourche 34 comportent sur le chant 54 dirigé vers l'extrémité 9 de la première tringle de verrouillage 7 un décrochement 55 pourvu d'un té­ton de commande 56 s'engageant dans un orifice 57 réalisé dans ladite extrémité 9 de la première tringle de verrouillage 7. Ainsi, cette der­nière est guidée, d'une part, par la face interne 4 de la têtière 5, et, d'autre part, par le décrochement 55 de la fourche 34. Pour verrouiller cette liaison constituée par l'interaction du téton 56 et de l'orifice 57, on pourvoit la fourche 34 d'au moins un moyen de guidage.Either one of the branches 35, 36, or the two branches 35, 36 of the fork 34 have on the edge 54 directed towards the end 9 of the first locking rod 7 a recess 55 provided with a control stud 56 engaging in an orifice 57 produced in said end 9 of the first locking rod 7. Thus, the latter is guided, on the one hand, by the internal face 4 of the headrest 5, and, on the other hand, by the step 55 of the fork 34. To lock this connection formed by the interaction of the stud 56 and the orifice 57, the fork 34 is provided with at least one guide means.

Ce moyen de guidage peut être constitué par un téton ou une languette 58 faisant saillie par rapport à la face externe 59 de la branche 35 et coulissant dans une lumière oblongue 60 réalisée dans la paroi latérale 41 du boîtier 2. On peut parfaire ce guidage en pourvoyant la face ex­terne 61 de l'aile 43 de la branche 36 d'un téton ou d'une languette saillante 62 coulissant dans une lumière oblongue 63 réalisée dans la pa­roi latérale 46 du boîtier 2.This guide means can be constituted by a stud or a tongue 58 projecting relative to the external face 59 of the branch 35 and sliding in an oblong slot 60 produced in the side wall 41 of the housing 2. This guidance can be improved by providing the external face 61 of the wing 43 of the branch 36 with a stud or a protruding tongue 62 sliding in an oblong opening 63 made in the side wall 46 of the housing 2.

Avantageusement, les deux lumières oblongues 60, 63 ne se font pas fa­ce mais sont décalées l'une par rapport à l'autre dans le sens de la course de la fourche 34. De ce fait, le guidage de cette dernière s'effec­tue sur une certaine longueur et on consolide ledit guidage. Ainsi, il devient possible d'allonger la course de la fourche 34 et, par voie de conséquence, la course des deux tringles de verrouillage 7, 8. Bien entendu, la longueur des lumières oblongues 60, 63 est au moins égale à la longueur de la course de la fourche 34.Advantageously, the two oblong slots 60, 63 do not face each other but are offset with respect to each other in the direction of travel of the fork 34. As a result, the latter is guided on a certain length and consolidating said guide. So, he becomes possible to lengthen the stroke of the fork 34 and, consequently, the stroke of the two locking rods 7, 8. Of course, the length of the oblong slots 60, 63 is at least equal to the length of the stroke fork 34.

Par le fait que le plan médian de la fourche 34 est désaxé par rapport au plan médian 39 du fouillot 6, on obtient un autre avantage. En effet, il devient possible de réaliser la denture 15 dans le chant opposé 64 de l'extrémité 9 de la première tringle de verrouillage 7, ce qui permet, en rapprochant l'élément inverseur 16 de la face interne 45 de la paroi latérale 46 du boîtier 2, de consolider le maintien dudit élément inver­seur 16. De ce fait, l'extrémité 10 de la seconde tringle de verrouillage 8 comporte une denture latérale ouverte 18, ce qui facilite l'interpéné­tration des dents de l'élément inverseur 16 et celles de la denture la­térale ouverte 18 de l'extrémité 10 de la seconde tringle de verrouillage 8. Ainsi, il est possible de désaxer la lumière de dégagement 32 et de la disposer du côté de la denture latérale ouverte 18.By the fact that the median plane of the fork 34 is offset from the median plane 39 of the follower 6, another advantage is obtained. Indeed, it becomes possible to make the toothing 15 in the opposite edge 64 of the end 9 of the first locking rod 7, which allows, by bringing the reversing element 16 closer to the inner face 45 of the side wall 46 of the housing 2, to consolidate the retention of said reversing element 16. As a result, the end 10 of the second locking rod 8 has an open lateral toothing 18, which facilitates the interpenetration of the teeth of the reversing element 16 and those of the open lateral toothing 18 of the end 10 of the second locking rod 8. Thus, it is possible to offset the clearance light 32 and to arrange it on the side of the open lateral toothing 18.
