Description

La présente invention concerne un dispositif de déverrouillage pour le dégagement d'une tige portante guidée d'appui-tête, où il est prévu à l'extrémité libre de la tige portante un rétrécissement coopérant avec un verrou sollicité par ressort lorsque la longueur maximale de déploiement de I'appui-tte est atteinte, et où ce verrou peut être débloqué par l'intermédiaire d'un organe de commande accessible au niveau du bord supérieur du dossier, dans lequel l'organe de commande est agencé sous la forme d'une tige d'actionnement orientée à peu près dans la direction axiale de la tige portante, et qui, par sa manoeuvre, tend à permettre le déplacement du verrou dans une position de déverrouillage, tandis que, lors d'un nouvel enfoncement de la tige portante, le verrou est débloqué par celle-ci, et peut à nouveau être~ramené en position active au retour de ladite tige d'actionnement, conformément au brevet principal. The present invention relates to an unlocking device for the release of a guide rod carrying a headrest, where there is provided at the free end of the supporting rod a narrowing cooperating with a bolt biased by spring when the maximum length of deployment of the headrest is reached, and where this lock can be released by means of a control member accessible at the upper edge of the backrest, in which the control member is arranged in the form of an actuating rod oriented approximately in the axial direction of the bearing rod, and which, by its operation, tends to allow the displacement of the bolt in an unlocked position, while, when the rod is pressed again bearing, the lock is released by the latter, and can again be brought back to the active position upon return of said actuating rod, in accordance with the main patent.

Un tel dispositif de déverrouillage permet, en cas de besoin, après suppression de la fixation, d'enlever facilement l'appui-tête avec les deux mains, et, après une nouvelle mise en place de l'appui-tete, un rétablissement automatique de la fixation. Such an unlocking device allows, if necessary, after removal of the attachment, to easily remove the headrest with both hands, and, after a new installation of the headrest, automatic recovery fixing.

L'invention a pour but, en conservant les avantages décrits, de proposer un agencement particulier du dispositif de déverrouillage qui soit approprié pour la fabrication en grande série, tout en restant de manoeuvre aisée. The object of the invention is, while retaining the advantages described, to propose a particular arrangement of the unlocking device which is suitable for mass production, while remaining easy to maneuver.

Ce problème est résolu en ce que la tige d1action- nement reçoit de façon articulée, à son extrémité inférieure, un bras d'un levier à deux bras, monté de façon à pouvoir pivoter sur une partie fixe d'obturation entourant un guide d'appui-tête, en ce que du verrou fait saillie un étrier comportant deux zones d'appui definissant pour un des bras du levier deux positions limites déterminées, et et en ce que, lorsque la tige d'actionnement est déplacée vers le bas en opposition à la force d'un ressort, ledit bras du levier est déplacé dans sa position limite inférieure et simultanément le verrou est dégagé du rétrécissement, l'autre bras étant amené par pivotement en travers de la voie de glissement suivie par la tige portante. This problem is solved in that the actuating rod receives in an articulated manner, at its lower end, an arm of a two-arm lever, mounted so as to be able to pivot on a fixed closure part surrounding a guide. headrest, in that from the bolt protrudes a stirrup comprising two support zones defining for one of the arms of the lever two determined limit positions, and and in that, when the actuating rod is moved down in opposition by the force of a spring, said lever arm is moved to its lower limit position and simultaneously the latch is released from the narrowing, the other arm being brought by pivoting across the sliding track followed by the supporting rod.

Selon un autre aspect avantageux de l'invention, l'extrémité supérieure de la tige d'actionnement est guidée dans un palier formé sur le guide d'appui-tête -en passant au travers d'une oreille située sur le côté supérieur du dossier et servant au passage de la tige portanteà peu près parallèlement à l'axe de la tige portante. r
On obtient une structure plus simple lorsque le verrou est relié de façon monobloc au guide d'appui-tête.According to another advantageous aspect of the invention, the upper end of the actuating rod is guided in a bearing formed on the headrest guide - passing through an ear located on the upper side of the backrest and serving for the passage of the carrying rod approximately parallel to the axis of the carrying rod. r
A simpler structure is obtained when the lock is connected in one piece to the headrest guide.

D'autres caractéristiques et avantages de l'invention seront mis en évidence dans la suite de la description, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels - la figure 1 représente un dispositif de déverrouillage
pour une tige portante d'appui-tête conforme à l'inven
tion, comportant un.verrou s'appuyant sur la périphérie
de la tige portante, - la figure 2 montre l'agencement de la figure 1 lorsque le
dispositif de déverrouillage entre en action, - la figure 3 montre le dispositif de déverrouillage lors
que la tige d'actionnement est enfoncée et que le ver
rou est écarté par pivotement.Other characteristics and advantages of the invention will be highlighted in the following description, given by way of nonlimiting example, with reference to the appended drawings in which - FIG. 1 represents an unlocking device
for a supporting headrest rod in accordance with the invention
tion, comprising a lock leaning on the periphery
of the supporting rod, - Figure 2 shows the arrangement of Figure 1 when the
unlocking device comes into action, - Figure 3 shows the unlocking device during
that the actuation rod is pressed and that the worm
rou is swiveled away.

Une tige portante 1 d'un appui-tête (non représenté) réglable graduellement en hauteur par translation, est montée dans un guide d'appui-tête 2 monté sur un cadre de dossier 3 , le guide 2 se prolonge à son extrémité inférieure par un verrou 4 sur lequel est formé un étrier 5 comportant deux zones d'appui 6 et 7. Le guide d'appui-tête 2 est entouré par une partie d'obturation 8 également montée sur le cadre de dossier 3, et recevant un ressort 9 sollicitant le verrou 4 ; il est de plus prévu, en bas de la partie d'obturation 8, un support 10 pour un levier 11 à deux bras. L'un des bras 12 est articulé sur l'extrémité inférieure 13 d'une tige d'actionnement 15, représentant une partie d'un organe de commande 14, et qui est associée à un ressort 16.L'extrémité supérieure 17 de la tige d'actionnement 15 est reçue dans un palier 18 du guide d'appuitête 2, et passe au travers d'un oeillet de passage 20 prévu sur le coté supérieur du dossier 19 pour la tige portante 1. La tige portante 1 est pourvue d'un rétrécissement 22 à son extrémité libre 21. A supporting rod 1 of a headrest (not shown) gradually adjustable in height by translation, is mounted in a headrest guide 2 mounted on a backrest frame 3, the guide 2 extends at its lower end by a lock 4 on which is formed a stirrup 5 comprising two support zones 6 and 7. The headrest guide 2 is surrounded by a closure part 8 also mounted on the back frame 3, and receiving a spring 9 requesting the lock 4; there is also provided, at the bottom of the closure part 8, a support 10 for a lever 11 with two arms. One of the arms 12 is articulated on the lower end 13 of an actuating rod 15, representing a part of a control member 14, and which is associated with a spring 16. The upper end 17 of the actuating rod 15 is received in a bearing 18 of the appetite guide 2, and passes through a passage eyelet 20 provided on the upper side of the backrest 19 for the supporting rod 1. The supporting rod 1 is provided with 'A narrowing 22 at its free end 21.

Dans la position de la tige portante 1 illustrée à la figure 1, le verrou 4 s'appuie contre la périphérie de la tige portante 1, et celle-ci peut coulisser librement vers le haut ou vers le bas. La tige d'actionnement- 15 est alors placée dans sa position supérieure, et le bras 12 du levier à deux bras 11 se trouve dans une position limite déterminée correspondant à la zone d'appui 6 de l'étrier 5, tandis que le second bras 23 s'appuie contre la partie d'obturation 8, à l'intérieur de celle-ci. In the position of the supporting rod 1 illustrated in FIG. 1, the latch 4 bears against the periphery of the supporting rod 1, and the latter can slide freely up or down. The actuating rod 15 is then placed in its upper position, and the arm 12 of the two-arm lever 11 is in a determined limit position corresponding to the bearing area 6 of the stirrup 5, while the second arm 23 bears against the shutter part 8, inside the latter.

Lorsque la tige portante 1 -comme le montre la figure 2- est tirée complètement vers le haut, le verrou 4 sollicité par le ressort 9 se déplace alors contre le rétrécissement 22 et limite ainsi le mouvement de sortie par butée de l'extrémité de la tige portante. Lorsque la tige d'actionnement 15 est poussée vers le bas, conformément à la figure 3, il se produit un pivotement du levier 11 à deux bras, dont le bras 12 passe maintenant dans son autre position limite déterminée correspondant à la zone d'appui 7 de l'étrier 5, tandis que son autre bras 23 quitte sa position escamotée pour se placer en travers du trajet suivi par la tige portante 1. Au cours de ce mouvement, le verrou 4 est dégagé du rétrécissement 22 par pivotement, de sorte que la tige portante 1 peut être tirée vers le haut et l'appui-tête enlevé. When the supporting rod 1 -as shown in Figure 2- is pulled completely upwards, the latch 4 urged by the spring 9 then moves against the narrowing 22 and thus limits the exit movement by abutment from the end of the bearing rod. When the actuating rod 15 is pushed downwards, in accordance with FIG. 3, there is a pivoting of the lever 11 with two arms, the arm 12 of which now passes into its other determined limit position corresponding to the support zone 7 of the stirrup 5, while its other arm 23 leaves its retracted position to be placed across the path followed by the supporting rod 1. During this movement, the latch 4 is released from the narrowing 22 by pivoting, so that the supporting rod 1 can be pulled upwards and the headrest removed.

Lors d'une nouvelle introduction de la tige portante 1, celle-ci vient buter par son extrémité libre contre le second bras 23 du levier 11, lequel exécute alors un mouvement inverse, de sorte que le dispositif dW déverrouillage et la tige portante reprennent à nouveau la position initiale représentée sur la figure 1.  During a new introduction of the carrying rod 1, it abuts by its free end against the second arm 23 of the lever 11, which then performs a reverse movement, so that the unlocking device dW and the carrying rod resume at again the initial position shown in Figure 1.
