Description

Dispositif de réglage longitudinal de la position d'un élément, partie d'assise ou de dossier constitutif d'un siège automobile pour enfant. Device for longitudinally adjusting the position of an element, part of the seat or backrest constituting a car seat for a child.
La présente invention a pour un objet un dispositif de réglage longitudinal de la position d'un élément, partie d'assise ou de dossier, constitutif d'un siège automobile pour enfant.The present invention has for one object a longitudinal adjustment device of the position of an element, part of seat or backrest, constituting a child car seat.
Un siège automobile pour enfant comprend un châssis supportant une coque comprenant une assise et un dossier, l'assise possédant généralement des bords latéraux remontant pour former accoudoirs, et le dossier comportant des retours latéraux pour caler la partie supérieure du corps de l'enfant. La coque est revêtue d'une housse assurant la finition et le confort de l'enfant. Le châssis sur lequel est montée la coque se résume souvent à une embase qui est destinée être posée sur le siège, et vis-à-vis de laquelle, l'ensemble de la coque peut effectuer un mouvement de coulissement accompagné d'un mouvement de rotation pour permettre une inclinaison plus ou moins importante de l'ensemble de la coque.A child car seat comprises a frame supporting a shell comprising a seat and a backrest, the seat generally having side edges up to form armrests, and the backrest comprising lateral returns to wedge the upper part of the body of the child. The shell is covered with a cover ensuring the finish and comfort of the child. The frame on which the hull is mounted is often a base that is intended to be placed on the seat, and vis-à-vis which, the entire hull can perform a sliding movement accompanied by a movement of rotation to allow more or less inclination of the entire hull.
Généralement, des crémaillères sont prévues dans l'assise, comportant des crans ouverts vers le haut, dans lesquels est destinée à pénétrer une traverse portée par un levier articulé sur la coque autour d'un axe parallèle à celui de la traverse. Ce levier est maintenu en position poussée vers le bas par un ressort prenant appui sous la face inférieure de la coque, afin de maintenir la traverse en position engagée dans les crémaillères de l'embase. Pour changer de position il convient que l'utilisateur soulève le levier qui est situé sous la partie avant de l'assise, pour dégager la traverse des crans des crémaillères dans lesquels elle est engagée et qu'il déplace la coque vis-à-vis de l'embase pour l'amener dans une nouvelle position avant de relâcher le levier permettant à la traverse de pénétrer dans une autre série de crans des crémaillères. Cette manœuvre n'est pas facile à effectuer, car le levier est peu accessible. En outre, le ressort assurant le maintien de la coque en position vis-à-vis de l'embase prend appui sous la coque, et peut être contraint sous l'effet de mouvements de l'enfant pouvant condurie éventuellement à un déverouillage accidentel, notamment en cas de choc, où la pression exercée par l'enfant sur la coque peut varier fortement.Generally, racks are provided in the seat, having notches open upwards, in which is intended to penetrate a cross carried by a lever hinged to the hull about an axis parallel to that of the cross. This lever is maintained in the downwardly pushed position by a spring bearing under the underside of the shell, in order to maintain the cross member in the engaged position in the racks of the base. To change position, the user must lift the lever located under the front part of the seat, to clear the cross bar of the notches in which it is engaged and that it moves the shell vis-à-vis the base to bring it into a new position before releasing the lever allowing the cross to enter another series of notches rack. This maneuver is not easy to perform because the lever is not very accessible. In addition, the spring ensuring the maintenance of the hull in position vis-à-vis the base is supported under the hull, and can be forced under the effect of the child's movements may eventually lead to accidental unlocking, especially in case of shock, where the pressure exerted by the child on the hull can vary greatly.
Le problème technique à la base de l'invention est la réalisation d'un dispositif de réglage longitudinal de la position d'un élément, partie d'assise ou de dossier consitutif d'un siège automobile pour enfant, visant à permettre un réglage très facile de cet élément, ce dispositif assurant une parfaite sécurité après positionnement, et ce dispositif étant tel qu'il peut s'appliquer à différents éléments du siège, permettant ainsi de réaliser une transformation du siège afin de permettre de l'utiliser soit pour de très jeunes enfants, soit pour des enfants, soit encore comme réhausseur pour des enfants plus grands. Il convient donc de pouvoir régler la position de l'assise, indépendamment de celle du dossier, et de pouvoir régler la position d'un élément de confort disposé à la partie supérieure du dossier, appelé têtière.The technical problem underlying the invention is the production of a device for longitudinally adjusting the position of an element, seat part or consitutive backrest of a car seat for children, to allow a very fine adjustment. easy of this element, this device ensuring a perfect security after positioning, and this device is such that it can be applied to different elements of the seat, thus allowing a transformation of the seat to allow it to be used either for very young children, or for children, still as booster for larger children. It is therefore necessary to adjust the position of the seat, independently of that of the backrest, and to be able to adjust the position of a comfort element disposed at the upper part of the folder, called headrest.
A cet effet, l'invention concerne un dispositif de réglage longitudinal de la position d'un élément, partie d'assise ou de dossier, consitutifs d'un siège automobile pour enfants, caractérisé en ce qu'il comporte :To this end, the invention relates to a longitudinal adjustment device for the position of an element, seat part or backrest, constituting a car seat for children, characterized in that it comprises:
- au moins une crémaillère ménagée dans une partie fixe, embase d'assise ou dossier, et orientée longitudinalement au déplacement souhaité,at least one rack made in a fixed part, seat base or backrest, and oriented longitudinally to the desired movement,
- un support solidaire de l'élément à régler, s'étendant parallèlement à chaque crémaillère et comportant des moyens de guidage perpendiculairement au support et à chaque crémaillère d'une tige de verrouillage orthogonale à la direction de déplacement,a support integral with the element to be adjusted, extending parallel to each rack and having guide means perpendicular to the support and at each rack of a locking rod orthogonal to the direction of movement,
- un coulisseau, monté sur le support, entre celui-ci et la ou les crémaillère(s), coulissant vis-à-vis du support dans la direction de déplacement de celui-ci, le coulisseau comportant une lumière allongée inclinée par rapport à la direction de mouvement de la tige de verrouillage, la lumière du coulisseau étant traversée par la tige de verrouillage et permettant, dans une première position le maintien de la tige de verrouillage dans chaque crémaillère et dans une seconde position le dégagement de la tige de verrouillage vis-à-vis de chaque crémaillère, et - un ressort monté entre le support et le coulisseau, maintenant normalement celui-ci dans une position dans laquelle la lumière inclinée permet l'introduction de la tige de verrouillage dans chaque crémaillère.a slide, mounted on the support, between the latter and the rack or rails, sliding relative to the support in the direction of movement thereof, the slide having an elongate slot inclined with respect to the direction of movement of the locking rod, the lumen of the slide being traversed by the locking rod and allowing, in a first position, the locking rod in each rack and in a second position the release of the locking rod to each rack, and - a spring mounted between the support and the slide, normally holding it in a position in which the inclined light allows the introduction of the locking rod in each rack.
Pour effectuer le réglage de la position d'un élément, l'opérateur doit actionner le coulisseau, afin de faire varier la position relative de la lumière du coulisseau et de la tige de verrouillage. En actionnant le coulisseau, la tige de verrouillage est déplacée perpendiculairement au support, pour être dégagée de la crémaillère dans laquelle elle était bloquée pour assurer le verrouillage de la partie d'assise ou de dossier. En maintenant le coulisseau dans cette position de dégagement de la tige de verrouillage, la partie d'assise ou de dossier peut être déplacée par rapport au reste de la structure jusque dans la nouvelle position souhaitée, position dans laquelle l'opérateur relâche le coulisseau qui ramène la tige de verrouillage dans une nouvelle position de blocage à l'intérieur de crans d'une ou deux crémaillères.In order to adjust the position of an element, the operator must actuate the slider in order to vary the relative position of the slider light and the locking rod. By actuating the slide, the locking rod is moved perpendicularly to the support, to be released from the rack in which it was locked to ensure the locking of the seat or backrest portion. By maintaining the slide in this position of disengagement of the locking rod, the seat or backrest portion can be moved relative to the rest of the structure to the new desired position, position in which the operator releases the slider which returns the locking rod in a new locking position within notches of one or two racks.
Il s'agit donc d'une structure simple, ne nécessitant qu'un mouvement simple, puisqu'il s'agit d'un mouvement de coulissement parallèlement à la partie qui doit être déplacée et réglée. Il peut être noté qu'il n'y a pas de risque de déplacement accidentel de cette partie, comme tel est le cas avec les dispositifs déjà connus, dans la mesure où le coulisseau ne peut se déplacer accidentellement si une pression plus ou moins forte est exercée sur l'assise ou le dossier. Suivant une caractéristique de l'invention, ce dispositif comporte deux crémaillères de verrouillage.It is therefore a simple structure, requiring only a simple movement, since it is a sliding movement parallel to the part to be moved and adjusted. It may be noted that there is no risk of accidental displacement of this part, as is the case with the devices already known, insofar as the slide can not move accidentally if a more or less strong pressure is exercised on the seat or back. According to a feature of the invention, this device comprises two locking racks.
Avantageusement les moyens de guidage de la tige de verrouillage sont constitués par deux chapes.Advantageously, the guide means of the locking rod are constituted by two clevises.
Suivant une forme d'exécution de l'invention, dans le cas du réglage de l'assise d'un siège, chaque crémaillère est fixée sur l'embase ou en fait partie intégrante, le support est fixé sous l'assise, et le coulisseau et le ressort associé sont ménagés afin qu'un déverrouillage soit obtenu par traction sur une poignée qui, solidaire du coulisseau, est située sous l'assise et à l'avant de celle-ci, la lumière ménagée dans le coulisseau étant inclinée de haut en bas et de l'arrière vers l'avant.According to one embodiment of the invention, in the case of adjusting the seat of a seat, each rack is fixed to the base or an integral part, the support is fixed under the seat, and the slider and the associated spring are provided so that an unlocking is obtained by pulling on a handle which, secured to the slider, is located under the seat and in front of it, the light in the slider being inclined by up and down and back to the front.
Le réglage de là position de l'assise est très pratique, car il suffit à un opérateur d'appuyer un pouce sur la partie avant de l'assise, et de tirer la poignée solidaire du coulisseau avec les autres doigts de la même main, exerçant ainsi un effet de pince. Lorsque la traction exercée par les autres doigts de la main est relâchée, le coulisseau est ramené dans sa position de verrouillage grâce au ressort.Adjusting the position of the seat is very practical, because it is sufficient for an operator to press a thumb on the front part of the seat, and pull the handle secured to the slide with the other fingers of the same hand, thus exerting a pincer effect. When the traction exerted by the other fingers of the hand is released, the slide is returned to its locking position by means of the spring.
Suivant une forme d'exécution de ce dispositif, l'assise est articulée autour d'un axe horizontal sur le bord inférieur d'un tronçon de dossier, dont le bord supérieur est articulé autour d'un axe horizontal sur un châssis de support du dossier, les deux crémaillères de l'assise étant inclinées de bas en haut et de l'arrière vers l'avant.According to one embodiment of this device, the seat is articulated around a horizontal axis on the lower edge of a backrest section, whose upper edge is articulated about a horizontal axis on a support frame of the backrest, the two racks of the seat being inclined from bottom to top and back to front.
Cet agencement permet de maintenir l'assise en position horizontale, ou sensiblement horizontale, quelle que soit l'avance de l'assise par rapport à l'embase, tout en assurant un bon confort pour l'enfant dans la mesure où l'extrémité arrière de l'assise est articulée sur le bord inférieur d'un tronçon de dossier. Suivant une autre caractéristique de l'invention, dans le cas du réglage en hauteur d'une partie de dossier constituée par une têtière, le châssis comporte au moins une ouverture verticale dont les bords tournés vers l'arrière forment deux crémaillères, le support équipé de la tige de verrouillage et le coulisseau associé étant disposés sur la face postérieure du châssis et le support étant solidarisé à travers les ouvertures du châssis, avec une plaque dorsale qui, portant la têtière, est guidée verticalement sur la face avant du châssis.This arrangement makes it possible to maintain the seat in a horizontal or substantially horizontal position, whatever the advance of the seat relative to the base, while ensuring a good comfort for the child as far as the end is concerned. back of the seat is articulated on the lower edge of a backrest section. According to another characteristic of the invention, in the case of height adjustment of a part of the backrest constituted by a headrest, the frame comprises at least one vertical opening whose edges turned towards the rear form two racks, the support equipped the locking rod and the associated slide being disposed on the rear face of the frame and the support being secured through the openings of the frame, with a back plate which, carrying the headrest, is guided vertically on the front face of the frame.
Le réglage en hauteur de la partie supérieure du dossier constituée par une têtière, permet une utilisation du siège durant une période plus longue que celle obtenue avec les sièges enfants traditionnels, dans la mesure où la hauteur du dossier peut augmenter en même temps que l'enfant grandit.The height adjustment of the upper part of the backrest consists of a headrest, allows use of the seat for a longer period than that obtained with traditional child seats, since the height of the backrest can increase at the same time as the child grows up.
Afin d'améliorer le caractère pratique du réglage de la têtière, le coulisseau et le ressort associé sont ménagés afin qu'un déverrouillage soit obtenu par traction verticale de bas en haut sur une poignée solidaire du coulisseau et située à l'extrémité supérieure de celui-ci, la lumière ménagée dans le coulisseau étant orientée de l'avant vers l'arrière et de haut en bas.In order to improve the practical nature of the adjustment of the headrest, the slider and the associated spring are arranged so that an unlocking is obtained by vertical traction upwards on a handle secured to the slider and located at the upper end of the Here, the light formed in the slide being oriented from front to rear and from top to bottom.
Avantageusement, la tige de verrouillage est équipée de deux doigts parallèles destinés à pénétrer dans les crémaillères du châssis du dossier. Cela permet de loger la tige de verrouillage dans un boîtier prenant appui sur la face arrière du châssis du siège, seuls les doigts solidaires de l'axe de verrouillage faisant saillie à l'intérieur des crémaillères.Advantageously, the locking rod is equipped with two parallel fingers intended to penetrate the racks of the backrest frame. This accommodates the locking rod in a housing resting on the rear face of the seat frame, only the fingers integral with the locking pin projecting inside the racks.
De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution de dispositif appliqué respectivement à l'assise d'un siège et à la têtière disposée à la partie supérieure du siège.In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of non-limiting examples, two embodiments of device applied respectively to the seat of 'a seat and the headrest arranged at the top of the seat.

La figure 1 représente un siège automobile pour enfant désigné par la référence générale 2 comportant une embase 3 et un châssis de dossier 4. Sur l'embase 3 est montée une coque 5 dont la partie centrale 6 forme l'assise et dont les deux retours latéraux 7 forment des accoudoirs. Dans la forme d'exécution représentée au dessin, le bord arrière de l'assise est articulé autour d'un axe horizontal 8 sur le bord inférieur d'un tronçon 9 de dossier, dont la partie supérieure est elle-même articulée autour d'un axe horizontal 10 sur le châssis du dossier. Le dossier est équipé dans sa partie supérieure d'une têtière 12 réglable en hauteur. L'ensemble de ces principaux éléments est revêtu d'éléments de rembourrage, non représentés au dessin, ménagés par exemple dans une housse.FIG. 1 represents a child car seat designated by the general reference 2 comprising a base 3 and a backrest frame 4. On the base 3 is mounted a shell 5 whose central portion 6 forms the seat and whose two returns side 7 form armrests. In the embodiment shown in the drawing, the rear edge of the seat is hinged about a horizontal axis 8 on the lower edge of a section 9 of the backrest, whose upper part is itself hinged around a horizontal axis 10 on the backrest frame. The back is equipped in its upper part with a headrest 12 adjustable in height. All of these main elements are covered with padding elements, not shown in the drawing, arranged for example in a cover.
L'embase 3 comporte deux ailes verticales orientées longitudinalement, c'est-à-dire de l'arrière vers l'avant, dans lesquelles sont ménagées trois encoches 13 formant, avec le bord supérieur, une crémaillère 14. Il doit être noté que la crémaillère 14 est inclinée de bas en haut et de l'arrière vers l'avant.The base 3 comprises two vertical wings oriented longitudinally, that is to say from the rear to the front, in which are formed three notches 13 forming, with the upper edge, a rack 14. It should be noted that the rack 14 is inclined from the bottom upwards and from the rear to the front.
Sur la face inférieure de l'assise est monté un support 15, qui peut éventuellement appartenir au fond même de l'assise. Sur ce support sont disposées deux chapes 16 parallèles, tournées vers le bas. Ces chapes sont verticales. Ces chapes 16 servent au guidage vertical d'une tige de verrouillage horizontale, destinée à s'engager dans l'une deux encoches 13 en vis-à-vis appartenant aux deux crémaillères 14, pour maintenir l'assise dans une position déterminée. Sur la face inférieure du support 15 est monté, coulissant longitudinalement, un coulisseau 18, maintenu poussé vers l'arrière par l'intermédiaire d'un ressort 19 dont l'autre extrémité prend appui contre une butée 20 solidaire du support 16. A l'intérieur du coulisseau 18 est ménagée une lumière allongée transversale 22, destinée au passage de l'axe de verrouillage 17, incliné de haut en bas et de l'arrière vers l'avant. La distance verticale entre les deux extrémités de la lumière 22 est supérieure à la profondeur des encoches 13 des crémaillères 14. Le coulisseau 18 est solidaire, au niveau de sa face avant, d'une poignée 23 disposée sous l'avant de l'assise du siège.On the underside of the seat is mounted a support 15, which may possibly belong to the bottom of the seat. On this support are disposed two parallel yokes 16, facing downwards. These screeds are vertical. These clevises 16 serve for the vertical guidance of a horizontal locking rod, intended to engage in one of two notches 13 vis-à-vis belonging to the two racks 14, to maintain the seat in a specific position. On the underside of the support 15 is mounted, sliding longitudinally, a slide 18, maintained pushed back by means of a spring 19 whose other end bears against a stop 20 secured to the support 16. A inside the slider 18 is provided an elongate transverse slot 22, for the passage of the locking pin 17, inclined from top to bottom and from rear to front. The vertical distance between the two ends of the lumen 22 is greater than the depth of the notches 13 of the racks 14. The slide 18 is secured, at its front face, with a handle 23 arranged under the front of the seat from the headquarters.
Le fonctionnement de ce dispositif est le suivant. Dans une première position représentée à la figure 2, la tige de verrouillage 17 est engagée dans les encoches 13 des crémaillères 14, situées le plus en arrière. Pour déplacer l'assise vers l'avant, l'opérateur exerce une traction sur la poignée 23, cette traction sur la poignée 23 déplaçant le coulisseau 18, qui va exercer, par le fond supérieur de sa lumière 22, un mouvement sur la tige de verrouillage 17, provoquant le passage de la tige de verrouillage d'une position basse dans laquelle elle est engagée dans deux encoches 13 à une position haute à laquelle elle échappe à ces deux encoches 13. L'assise peut alors être déplacée, la tige de verrouillage 17 étant maintenue en position haute. L'assise peut être amenée par exemple dans la position la plus avancée représentée à la figure 4. Dans cette position, l'opérateur cesse d'exercer une action sur la poignée 23, et le ressort 19 ramène le coulisseau 18 en arrière, permettant à la tige 17 de descendre à l'intérieur de la lumière 22 et de pénétrer dans les encoches 13 situées le plus en avant.The operation of this device is as follows. In a first position shown in Figure 2, the locking rod 17 is engaged in the notches 13 of the racks 14, located further back. To move the seat forward, the operator pulls on the handle 23, this traction on the handle 23 moving the slide 18, which will exert, by the upper bottom of its light 22, a movement on the rod locking 17, causing the passage of the locking rod from a low position in which it is engaged in two notches 13 to an upper position to which it escapes these two notches 13. The seat can then be moved, the rod locking 17 being held in the up position. The seat can be brought for example to the most advanced position shown in FIG. 4. In this position, the operator stops exerting an action on the handle 23, and the spring 19 brings the slide 18 backwards, allowing at the rod 17 to descend inside the light 22 and to enter the notches 13 located furthest forward.
Il doit être noté que, comme montré à la figure 4, l'assise 6 étant articulée par son extrémité arrière sur le bord inférieur d'un tronçon 9 de dossier, l'avant de l'assise se déplace vers le haut au cours de son mouvement d'avance, ce qui est rendu possible par la position inclinée des crémaillères 14. L'assise demeure ainsi horizontale.It should be noted that, as shown in Figure 4, the seat 6 being articulated by its rear end on the lower edge of a section 9 of the backrest, the front of the seat moves upwards during its movement in advance, which is made possible by the inclined position of the racks 14. The seat remains horizontal.
Cet agencement est très intéressant car le nombre de pièces mises en œuvre est très limité, et le réglage est très simple, pouvant être réalisé à l'aide d'une seule main, le pouce prenant appui sur la face avant de l'assise et les autres doigts de la main exerçant une traction sur la poignée 23. Il doit également être noté que le dispositif de réglage et de verrouillage n'est nullement perturbé par des chocs volontaires ou accidentels pouvant intervenir lors de l'utilisation du siège, comme tel est le cas avec les dispositifs connus précédemment. Les figures 6 à 8 représentent une application du dispositif selon l'invention à la fixation et au réglage vertical d'une têtière 12. Dans ce cas, le châssis comporte une ouverture verticale 25 dont les bords tournés vers l'arrière comportent des encoches 26 destinées à la formation de deux crémaillères 27. Sur la face arrière du châssis 4 est disposé un support 28 équipé d'une tige de verrouillage 29, laquelle tige de verrouillage 29 porte deux doigts 30 destinés à être engagés dans les encoches 26 des crémaillères. Sur le support 28 est destiné à être monté un coulisseau 32, comportant une lumière 33 inclinée de bas en haut et de l'arrière vers l'avant, cette lumière 33 étant destinée à être traversée par la tige de verrouillage 29. La tige de verrouillage 29 est guidée perpendiculairement au plan du châssis par des coulisseaux désignés par la référence 34. Le coulisseau 32 est prolongé vers le haut par une poignée d'actionnement 35, l'ensemble étant fermé par un capot 36 présentant une ouverture pour l'actionnement de la poignée 35. Un ressort 37 prend appui d'une part sur le coulisseau et d'autre part sur une butée 38 solidaire du capot 36. Le support 28 est rendu solidaire à travers l'ouverture 25 d'une plaque dorsale 39 guidée verticalement sur la face avant du châssis 25. Sur cette plaque dorsale 39 est fixée la têtière 40.This arrangement is very interesting because the number of parts used is very limited, and the adjustment is very simple, can be achieved with one hand, the thumb resting on the front of the seat and the other fingers of the hand exerting traction on the handle 23. It should also be noted that the adjustment and locking device is not affected by any deliberate or accidental shocks that may occur during the use of the seat, as such is the case with previously known devices. FIGS. 6 to 8 show an application of the device according to the invention to the fixing and the vertical adjustment of a headrest 12. In this case, the frame has a vertical opening 25 whose rearwardly facing edges have notches 26 for the formation of two racks 27. On the rear face of the frame 4 is disposed a support 28 equipped with a locking rod 29, which rod locking 29 carries two fingers 30 to be engaged in the notches 26 of the racks. On the support 28 is intended to be mounted a slide 32, having a slot 33 inclined upwards and from the rear towards the front, this slot 33 being intended to be traversed by the locking rod 29. locking 29 is guided perpendicular to the plane of the frame by sliders designated by the reference 34. The slider 32 is extended upwardly by an actuating handle 35, the assembly being closed by a cover 36 having an opening for actuation of the handle 35. A spring 37 is supported on the one hand on the slide and on the other hand on a stop 38 secured to the cover 36. The support 28 is secured through the opening 25 of a back plate 39 guided vertically on the front face of the frame 25. On this dorsal plate 39 is fixed the headrest 40.
En pratique, lorsque la têtière est dans la position représentée à la figure 6, et que l'on souhaite la déplacer vers le haut, il convient pour l'opérateur d'actionner la poignée 35 vers le haut, mouvement au cours duquel le coulisseau 32 se déplace à rencontre de l'action du ressort 39, la lumière 33 provoquant le déplacement vers l'arrière de la tige de verrouillage 29 et des doigts 30 qui échappent aux crans 26 de la crémaillère dans laquelle ils sont engagés. Il est alors possible à l'opérateur de déplacer la têtière verticalement, jusque dans une autre position, par exemple la position représentée à la figure 8, avant de relâcher la traction exercée sur la poignée 35. La têtière se trouve alors verrouillée dans une nouvelle position.In practice, when the headrest is in the position shown in Figure 6, and it is desired to move it upwards, it is appropriate for the operator to operate the handle 35 upwards, movement in which the slide 32 moves against the action of the spring 39, the light 33 causing the rearward movement of the locking rod 29 and the fingers 30 which escape the notches 26 of the rack in which they are engaged. It is then possible for the operator to move the headrest vertically to another position, for example the position shown in Figure 8, before releasing the tension exerted on the handle 35. The headrest is then locked in a new position. position.
Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant un dispositif de réglage simple et fiable de la position d'un élément de siège automobile pour enfant, permettant notamment la transformation et l'adaptation de ce siège pour améliorer le confort d'un enfant, ainsi que pour permettre une utilisation sur une plage d'âge plus importante.As can be seen from the foregoing, the invention brings a great improvement to the existing technique, by providing a simple and reliable adjustment device for the position of a car seat element for a child, notably enabling the transformation and adaptation of this seat to improve the comfort of a child, as well as to allow use over a longer age range.
