Abstract

The invention concerns a seat (1) comprising a back (2) provided in its upper part with a headrest (5) adjustable in height including two side walls (6, 7), designed to support the child's head, mounted mobile and guided horizontally on a support plate (9) vertically mobile along the back (2). Each of the side walls (6, 7) comprises a maneuvering finger (13, 14) which, when the support plate (9) moves vertically relative to the back (2), slides simultaneously in a horizontally elongated corresponding guiding slot (11, 12), formed in the support plate (9) and in an elongated corresponding guiding groove (18, 10) formed in the back (2), substantially inclined relative to the general axis (A) of the back (2) so as to move away towards the top of the back (2), such that the vertical movement of the support plate (9) relative to the back (2) causes the spacing of the side walls (6, 7) of the headrest (5) to be modified.

Description

Siège automobile pour enfant Child car seat
La présente invention concerne un siège automobile ou analogue pour enfant. Un tel siège comporte généralement une assise, un dossier et divers éléments de confort et de sécurité comme par exemple une têtière, ou appui-tête, en partie supérieure du dossier.The present invention relates to a car seat or the like for children. Such a seat generally comprises a seat, a backrest and various elements of comfort and safety such as for example a headrest, or headrest, in the upper part of the backrest.
La têtière est habituellement constituée d'une plaque de support formant l'appui-tête proprement dit et, en saillie de part et d'autre de l'appui- tête, de deux joues latérales qui "encadrent" la tête de l'enfant afin de la maintenir. Il est souvent possible d'adapter la hauteur de la têtière sur le dossier au fur et à mesure que l'enfant grandit. Pour ce faire, la plaque de support de la têtière est déplaçable verticalement le long du dossier, ce qui permet d'utiliser le siège durant une période relativement longue de la petite enfance.The headrest usually consists of a support plate forming the headrest itself and, projecting from both sides of the headrest, two lateral cheeks that "frame" the child's head in order to maintain it. It is often possible to adjust the height of the headrest on the backrest as the child grows up. To do this, the support plate of the headrest is movable vertically along the backrest, which allows to use the seat for a relatively long period of infancy.
Toutefois, l'écartement entre les joues latérales de la têtière étant fixe, un tel siège n'est pas tout à fait adapté pour les enfants en bas âge dont la tête est petite et doit être bien maintenue, en particulier durant leur sommeil. Entre les âges d'un an et de sept ans, la tête d'un enfant augmente en effet d'environ deux centimètres de largeur.However, the spacing between the side cheeks of the headrest being fixed, such a seat is not quite suitable for young children whose head is small and must be well maintained, especially during their sleep. Between the ages of one and seven years, the head of a child increases in effect by about two centimeters in width.
La présente invention vise à éviter cet inconvénient en proposant un siège automobile pour enfant dont la têtière soit ajustable à la fois en hauteur et en largeur, les opérations d'ajustement en hauteur et en largeur de la têtière étant rapides et simples à effectuer.The present invention aims to avoid this disadvantage by providing a car seat for children whose headrest is adjustable both in height and width, the adjustment operations in height and width of the headrest being fast and simple to perform.
A cet effet, l'invention a pour objet un siège automobile pour enfant tel que présenté ci-dessus, dans lequel les joues latérales de têtière sont mobiles et guidées horizontalement sur la plaque de support et chacune des joues latérales de la têtière comporte au moins un doigt de manœuvre apte, lors d'un déplacement vertical de la plaque de support par rapport au dossier, à simultanément coulisser, d'une part, dans une lumière de guidage correspondante, de forme horizontalement oblongue, formée dans la plaque de support, et d'autre part, dans une rainure de guidage correspondante formée dans le dossier, de forme oblongue, sensiblement inclinée par rapport à l'axe général du dossier de manière à s'en éloigner en se dirigeant vers le haut du dossier, de sorte que le déplacement vertical de la plaque de support par rapport au dossier s'accompagne d'une modification de l'écartement des joues latérales de la têtière. Ainsi, l'idée inventive consiste à asservir, par une solution simple et efficace, l'écartement des joues latérales de la têtière à la position de celle-ci par rapport au dossier. Les réglages en largeur et en hauteur de la têtière s'effectuent concomitamment, en une manipulation unique, garantissant la simplicité d'usage et l'évolutivité de ce siège pour enfant.For this purpose, the subject of the invention is a child car seat as shown above, in which the lateral headrest cheeks are movable and guided horizontally on the support plate and each of the lateral cheeks of the headrest comprises at least a maneuvering finger adapted, during a vertical displacement of the support plate relative to the backrest, to slide simultaneously, on the one hand, in a corresponding guiding light of horizontally oblong shape, formed in the support plate, and on the other hand, in a corresponding guide groove formed in the backrest, of oblong shape, substantially inclined relative to the general axis of the backrest so as to move away from it towards the top of the backrest, so that the vertical displacement of the support plate relative to the backrest is accompanied by a change in the spacing of the lateral cheeks of the headrest. Thus, the inventive idea is to enslave, by a simple and effective solution, the spacing of the lateral cheeks of the headrest to the position thereof relative to the folder. The width and height adjustments of the headrest are performed concomitantly, in a single manipulation, ensuring the ease of use and scalability of this child seat.
Le déplacement d'un doigt de manœuvre dans une lumière et une rainure oblongues permet de contrôler aisément et efficacement la hauteur et l'élargissement de la têtière.Moving an operating finger in an oblong slot and slot makes it easy and convenient to control the height and width of the faceplate.
Selon le même principe (mais en inversant la disposition précédente des doigts et rainures de guidage), l'invention a également pour objet un siège automobile pour enfant tel que présenté en introduction, dans lequel les joues latérales de têtière sont mobiles et guidées horizontalement sur la plaque de support, et le dossier comporte, de part et d'autre d'un plan médian vertical du dossier, au moins un doigt de manœuvre apte, lors d'un déplacement vertical de la plaque de support par rapport au dossier, à simultanément coulisser, d'une part, dans une lumière de guidage correspondante, de forme horizontalement oblongue, formée dans la plaque de support, et d'autre part, dans une rainure de guidage correspondante formée dans une joue latérale de la têtière, de forme oblongue, sensiblement inclinée par rapport à l'axe général du dossier de manière à s'en éloigner en se dirigeant vers le bas du dossier, de sorte que le déplacement vertical de la plaque de support par rapport au dossier s'accompagne d'une modification de l'écartement des joues latérales de la têtière.According to the same principle (but by reversing the previous arrangement of the fingers and guide grooves), the invention also relates to a car seat for children as presented in the introduction, wherein the side cheek of the headrest are movable and guided horizontally on the support plate, and the backrest comprises, on either side of a vertical median plane of the backrest, at least one suitable operating finger, during a vertical displacement of the support plate relative to the backrest, to simultaneously sliding, on the one hand, in a corresponding guiding light, of horizontally oblong shape, formed in the support plate, and on the other hand, in a corresponding guide groove formed in a side cheek of the headrest, of shape oblong, substantially inclined relative to the general axis of the backrest so as to move away from it by moving towards the bottom of the backrest, so that the vertical displacement of the sup plate relative to the backrest is accompanied by a change in the spacing of the lateral cheeks of the headrest.
De manière avantageuse, la plaque de support présente au moins une ouverture guide sangle pour une sangle de maintien de l'enfant, de sorte que la position verticale, par rapport au dossier, de la sangle de maintien est automatiquement ajustée, en même temps que la hauteur et la largeur de la têtière.Advantageously, the support plate has at least one strap guide opening for a child holding strap, so that the vertical position relative to the backrest of the support strap is automatically adjusted, at the same time as the height and width of the headrest.
Afin de guider le mouvement de translation horizontale des joues latérales de têtière sur la plaque de support, chacune des joues latérales de têtière peut présenter par exempleIn order to guide the horizontal translation movement of the lateral cheeks of the headrest onto the support plate, each of the lateral cheeks of the headrest may have, for example,
- au moins une nervure horizontale prévue pour coopérer avec une nervure horizontale correspondante de la plaque de support, et/ouat least one horizontal rib intended to cooperate with a corresponding horizontal rib of the support plate, and / or
- au moins une lumière de forme horizontalement oblongue formant glissière, prévue pour recevoir au moins un coulisseau solidaire de la plaque de support. D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante de deux exemples de réalisation de l'invention et des dessins annexés.at least one light of horizontally oblong shape forming a slide, designed to receive at least one slide integral with the support plate. Other characteristics and advantages of the invention will emerge more clearly on reading the following description of two exemplary embodiments of the invention and the appended drawings.

La figure 1 représente un siège automobile pour enfant désigné globalement par la référence 1.Figure 1 shows a child car seat generally designated by the reference 1.
Le siège 1 comporte une embase 3 sur laquelle est montée une coque dont une partie supérieure forme un dossier 2 et une partie inférieure forme une assise 4 avec deux retours latéraux formant des accoudoirs. L'ensemble de ces principaux éléments est revêtu d'éléments de rembourrage, non représentés au dessin, ménagés par exemple dans une housse.The seat 1 comprises a base 3 on which is mounted a shell whose upper part forms a backrest 2 and a lower part forms a seat 4 with two lateral returns forming armrests. All of these main elements are covered with padding elements, not shown in the drawing, arranged for example in a cover.
Le dossier 2 est équipé dans sa partie supérieure d'une têtière 5 réglable en hauteur, comprenant deux joues latérales 6 et 7 de section en forme de "L", prévues pour caler la tête de l'enfant.The backrest 2 is equipped in its upper part with a headrest 5 adjustable in height, comprising two side cheeks 6 and 7 of section L-shaped, provided to wedge the head of the child.
Comme indiqué sur la figure 2, les "fonds" de ces deux joues latérales 6 et 7 sont intercalés entre une platine appui-tête 8 et une plaque porte harnais 9 montée mobile verticalement sur le dossier 2.As indicated in FIG. 2, the "bottoms" of these two lateral cheeks 6 and 7 are interposed between a headrest plate 8 and a harness plate 9 mounted vertically on the backrest 2.
La platine appui-tête 8 est fixée en 8a et 8b (voir figure 4) par des vis ou des clips (non représentés) sur la plaque porte harnais 9 en 9a et 9b (voir figure 5).The headrest plate 8 is fixed at 8a and 8b (see Figure 4) by screws or clips (not shown) on the harness plate 9 at 9a and 9b (see Figure 5).
Les deux joues latérales 6 et 7 de la têtière 5 possèdent des nervures horizontales 21 , 22 (voir figure 3) qui coopèrent avec des nervures horizontales 10 ménagées sur la plaque porte harnais 9 (voir figure 5) pour guider la translation horizontale des joues latérales 6 et 7 par rapport à la plaque porte harnais 9 et à la platine appui-tête 8.The two lateral cheeks 6 and 7 of the headrest 5 have horizontal ribs 21, 22 (see FIG. 3) which cooperate with horizontal ribs 10 formed on the harness plate 9 (see FIG. 5) to guide the horizontal translation of the lateral cheeks. 6 and 7 with respect to the harness plate 9 and to the headrest plate 8.
La plaque porte harnais 9, représentée plus en détail sur la figure 5, présente deux lumières 11 et 12 de forme horizontalement oblongue, chacune traversée par un doigt de manœuvre 13, 14 de l'une des joues latérales 6, 7 de la têtière 5.The harness plate 9, shown in greater detail in FIG. 5, has two slots 11 and 12 of horizontally oblong shape, each traversed by a maneuvering finger 13, 14 of one of the lateral cheeks 6, 7 of the headrest 5. .
Les deux doigts 13, 14 assurent une synchronisation du déplacement horizontal des joues latérales 6, 7 de la têtière 5. La longueur des lumières 11 , 12 dans la plaque porte harnais 9 définit le débattement horizontal maximal des doigts de manœuvre 13, 14 des joues latérales 6, 7, et par conséquent l'écartement maximal des joues latérales 6, 7.The two fingers 13, 14 ensure a synchronization of the horizontal displacement of the lateral cheeks 6, 7 of the headrest 5. The length of the lights 11, 12 in the harness plate 9 defines the maximum horizontal movement of the operating fingers 13, 14 of the cheeks 6, 7, and consequently the maximum spacing of the side flanges 6, 7.

La plaque porte harnais 9 comporte aussi des nervures verticales 17 qui coopèrent avec des nervures verticales 23 du dossier 2 (voir figure 6) afin de guider le mouvement de translation verticale de la plaque porte harnais 9 sur le dossier 2.The harness plate 9 also has vertical ribs 17 which cooperate with vertical ribs 23 of the backrest 2 (see FIG. 6) in order to guide the vertical translation movement of the harness plate 9 on the backrest 2.
Comme indiqué sur la figure 6, le dossier 2 comporte deux rainures oblongues 18 et 19 symétriquement inclinées par rapport à l'axe général A du dossier 2, de manière à diverger en direction du haut du dossier 2. Les doigts de manœuvre 13, 14 des joues latérales 6, 7 de la têtière 5 coulissent dans ces rainures 18, 19 lors d'un déplacement vertical de la têtière 5 par rapport au dossier 2 du siège 1.As shown in Figure 6, the backrest 2 has two oblong grooves 18 and 19 symmetrically inclined relative to the general axis A of the backrest 2, so as to diverge towards the top of the backrest 2. The operating fingers 13, 14 of the lateral cheeks 6, 7 of the headrest 5 slide in these grooves 18, 19 during a vertical displacement of the headrest 5 with respect to the backrest 2 of the seat 1.
Ainsi, le déplacement vertical de la têtière 5 s'accompagne d'un déplacement horizontal des doigts de manœuvre 13, 14 des joues latérales 6,Thus, the vertical displacement of the headrest 5 is accompanied by a horizontal movement of the operating fingers 13, 14 of the lateral cheeks 6,
7 de la têtière 5, assurant ainsi un réglage de i'écartement desdites joues latérales 6, 7, c'est-à-dire de la largeur de la têtière 5, en fonction du réglage en hauteur de cette dernière sur le dossier 2 du siège 1.7 of the headrest 5, thus ensuring adjustment of the spacing of said lateral cheeks 6, 7, that is to say the width of the headrest 5, depending on the height adjustment of the latter on the backrest 2 of the seat 1.
En position basse (voir figure 7) de la têtière 5 par rapport au dossier 2, les deux joues latérales 6, 7 de la têtière 5 sont rapprochées. Les doigts de manœuvre 13, 14 des deux joues latérales 6, 7 sont situés à une extrémité inférieure des rainures de guidage 18, 19 du dossier 2 et viennent en butée contre le côté intérieur des lumières 11 , 12 de la plaque porte harnais 9.In the lower position (see Figure 7) of the headrest 5 relative to the backrest 2, the two lateral cheeks 6, 7 of the headrest 5 are close together. The operating fingers 13, 14 of the two lateral cheeks 6, 7 are located at a lower end of the guide grooves 18, 19 of the backrest 2 and abut against the inside of the slots 11, 12 of the harness plate 9.
En revanche, en position haute (voir figure 8) de la têtière 5 par rapport au dossier 2, les deux joues latérales 6, 7 de la têtière 5 sont écartées au maximum l'une de l'autre. Les doigts de manœuvre 13, 14 des deux joues latérales 6, 7 sont situés à une extrémité supérieure des rainures de guidage 18, 19 du dossier 2 et viennent en butée contre le côté extérieur des lumières 11 , 12 de la plaque porte harnais 9. Les figures 9 à 11 , sur lesquelles les numéros de référence précédents sont repris pour désigner des éléments similaires, représentent un autre exemple de siège automobile pour enfant selon l'invention, dans lequel la platine d'appui-tête et la plaque porte harnais sont une seule et même plaque 9 guidée verticalement sur la face avant du dossier 2. Sur la figure 9, seule la face arrière d'une moitié gauche de la plaque porte harnais 9 est visible. Cette moitié gauche comporte, en partie supérieure, deux parties formant coulisseau supérieur 25a, et en partie inférieure, une partie formant coulisseau inférieur 25b.In contrast, in the up position (see Figure 8) of the headrest 5 relative to the backrest 2, the two lateral cheeks 6, 7 of the headrest 5 are spaced at most from one another. The operating fingers 13, 14 of the two lateral flanges 6, 7 are located at an upper end of the guide grooves 18, 19 of the backrest 2 and abut against the outside of the openings 11, 12 of the harness plate 9. FIGS. 9 to 11, on which the preceding reference numerals are used to designate similar elements, represent another example of a child car seat according to the invention, in which the headrest plate and the harness plate are a single plate 9 guided vertically on the front of the backrest 2. In Figure 9, only the rear face of a left half of the harness plate 9 is visible. This left half comprises, in the upper part, two upper slider portions 25a, and in the lower part, a lower slider portion 25b.
Les coulisseaux supérieurs 25a sont montés coulissants dans une lumière (non représentée), de forme horizontalement oblongue, formant glissière en partie supérieure de la joue latérale gauche 6 de la têtière 5. De même, le coulisseau inférieur 25b est monté dans une lumière (non représentée), de forme horizontalement oblongue, formant glissière en partie inférieure de la joue 6. Bien entendu, la joue latérale 7 droite, non représentée sur la figure 9, présente également de façon symétrique deux glissières, l'une en partie supérieure et l'autre en partie inférieure de la joue 7, afin de recevoir des coulisseaux inférieur et supérieurs de la moitié droite (non représentée) de la plaque porte harnais 9.The upper slides 25a are slidably mounted in a slot (not shown), of horizontally oblong shape, forming a slide in the upper part of the left side cheek 6 of the headrest 5. Similarly, the lower slide 25b is mounted in a light (no shown), of horizontally oblong shape, forming a slider in the lower part of the cheek 6. Of course, the right side cheek 7, not shown in FIG. 9, also symmetrically has two sliders, one in upper and lower part of the cheek 7, to receive lower and upper slides of the right half (not shown) of the harness plate 9.
Les coulisseaux de la plaque porte harnais 9 possèdent une semelle élargie (non représentée), en saillie sur la face avant de la plaque porte harnais 9, qui assure une retenue, selon l'axe général A du dossier 2 et selon un axe perpendiculaire au plan général du dossier 2, de la joue latérale correspondante 6 ou 7 sur la plaque porte harnais 9, tout en autorisant les joues latérales 6, 7 de la têtière 5 à se déplacer en direction horizontale par rapport à la plaque porte harnais 9.The sliders of the harness plate 9 have an enlarged sole (not shown), projecting on the front face of the harness plate 9, which ensures a retention, along the general axis A of the backrest 2 and along an axis perpendicular to the general plan backrest 2, the corresponding side cheek 6 or 7 on the harness plate 9, while allowing the side cheeks 6, 7 of the headrest 5 to move in the horizontal direction relative to the harness plate 9.
Comme dans la forme de réalisation précédente, la synchronisation du déplacement des joues latérales 6, 7 est assurée au moyen d'un doigt de manœuvre 13, 14 de chacune des joues latérales 6, 7 qui traverse une lumière horizontale oblongue 11 , 12 correspondante de la plaque porte harnais 9, et coulisse dans une rainure de guidage (non représentée sur la figure 9) inclinée correspondante du dossier 2.As in the previous embodiment, the synchronization of the displacement of the lateral cheeks 6, 7 is ensured by means of a finger 13, 14 of each of the lateral cheeks 6, 7 which passes through an oblong horizontal light 11, 12 corresponding to the harness plate 9, and slides in a guide groove (not shown in FIG. 9) corresponding inclined backrest 2.
Ici, le doigt de manœuvre 13, la lumière 11 et la rainure de guidage correspondantes, sont agencés non plus en partie haute mais en partie centrale de la plaque porte harnais 9 et du "fond" de la joue latérale correspondante 6.Here, the operating finger 13, the corresponding light 11 and guide groove, are arranged no longer in the upper part but in the central part of the harness plate 9 and the "bottom" of the corresponding lateral cheek 6.
Par ailleurs, le dossier 2 comporte au moins une ouverture verticale 30 dont les bords tournés vers l'arrière forment deux crémaillères 31 , 32 orientées longitudinalement au déplacement souhaité de la têtière 5.Furthermore, the backrest 2 comprises at least one vertical opening 30 whose rearwardly facing edges form two racks 31, 32 oriented longitudinally to the desired displacement of the headrest 5.
Un dispositif 33 de réglage en hauteur de la têtière 5 par rapport au dossier 2 du siège est prévu qui comporte principalement un support de poignée 35 et une poignée de déverrouillage 34 accessible et actionnable par une ouverture dans le support de poignée 35.A device 33 for adjusting the height of the headrest 5 relative to the backrest 2 of the seat is provided which mainly comprises a handle support 35 and an unlocking handle 34 accessible and actuable by an opening in the handle support 35.
La poignée 34 est montée coulissante, parallèlement aux crémaillères 31 , 32, entre le support de poignée 35 et la face postérieure du dossier 2.The handle 34 is slidably mounted, parallel to the racks 31, 32, between the handle support 35 and the rear face of the backrest 2.
Le support de poignée 35 est disposé, parallèlement à chaque crémaillère 31 , 32, sur la face arrière du dossier 2 et solidarisé, à travers l'ouverture 30 du dossier 2, avec la plaque porte harnais 9 par un axe de liaison 37 qui traverse un téton 36 de fixation de la plaque porte harnais 9. Un axe de harnais 38 est fixé sur le support de poignée 35, en regard des ouvertures guide sangle 15, 16 de la plaque porte harnais 9. La poignée 34 est solidaire d'une rampe de guidage 38, orientée de l'avant vers l'arrière du dossier 2 et de haut en bas, et contre laquelle vient en appui une tige de verrouillage 39 orthogonale à la direction du déplacement souhaité de la têtière 5. La tige de verrouillage 39 est équipée de deux doigts parallèles destinés à pénétrer dans les encoches des crémaillères 31 , 32 du dossier 2.The handle support 35 is arranged, parallel to each rack 31, 32, on the rear face of the backrest 2 and secured, through the opening 30 of the backrest 2, with the harness plate 9 by a connecting pin 37 which passes through a pin 36 for fixing the harness plate 9. A harness pin 38 is fixed on the handle support 35, opposite the strap guide openings 15, 16 of the harness plate 9. The handle 34 is integral with a guide ramp 38, oriented from the front to the back of the backrest 2 and from top to bottom, and against which bears a locking rod 39 orthogonal to the direction of the desired movement of the headrest 5. The locking rod 39 is equipped with two parallel fingers intended to penetrate the notches of the racks 31, 32 of the backrest 2.
Comme illustré sur les figures 10 et 11 , une simple traction verticale, exercée de bas en haut sur la poignée 34 à rencontre d'un ressort de rappel 40 de la poignée 34, permet de déverrouiller le dispositif de réglage 33. Le ressort de rappel 40 prend appui d'une part sur une butée 41 solidaire du support de poignée 35 et d'autre part sur une butée 42 solidaire de la poignée 34.As illustrated in Figures 10 and 11, a simple vertical pull, exerted upwardly on the handle 34 against a return spring 40 of the handle 34, to unlock the adjusting device 33. The return spring 40 is supported on the one hand on a stop 41 secured to the handle support 35 and on the other hand on a stop 42 integral with the handle 34.
Au cours de ce mouvement, la rampe de guidage 38 repousse les doigts de la tige de verrouillage 39 hors des encoches des crémaillères 31, 32 du dossier 2 dans lesquelles ils sont engagés (voir figure 11).During this movement, the guide ramp 38 pushes the fingers of the locking rod 39 out of the notches of the racks 31, 32 of the folder 2 in which they are engaged (see Figure 11).
Il est alors possible à l'opérateur de déplacer la têtière 5 verticalement le long du dossier 2, jusque dans une autre position, par exemple la position représentée à la figure 8, avant de relâcher la traction exercée sur la poignée 34. La têtière 5 se trouve alors verrouillée dans une nouvelle position. Cet agencement est 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. En outre, le dispositif de réglage et de verrouillage 33 de la position de la têtière 5 n'est pas perturbé par des chocs pouvant intervenir lors de l'utilisation du siège 1. Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant un siège automobile pour enfant, permettant notamment la transformation et l'adaptation de ce siège pour permettre une utilisation sur une plage d'âge plus importante.It is then possible for the operator to move the headrest 5 vertically along the backrest 2, to another position, for example the position shown in Figure 8, before releasing the tension exerted on the handle 34. The headrest 5 is then locked in a new position. This arrangement is interesting because the number of parts implemented is very limited, and the setting is very simple, can be achieved with one hand. In addition, the adjustment and locking device 33 of the position of the headrest 5 is not disturbed by shocks that can occur during the use of the seat 1. As can be seen from the foregoing, the invention provides a great improvement to the existing technique, providing a car seat for children, including the transformation and adaptation of this seat to allow use over a longer age range.
Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce dispositif décrites ci-dessus, à titre d'exemple ; elle en embrasse au contraire, toutes les variantes de réalisation et d'application demeurant dans le cadre des revendications qui suivent. Par exemple, les formes des différentes lumières et rainures de guidage ne sont pas obligatoirement rectilignes. It goes without saying that the invention is not limited to the embodiments of this device described above, by way of example; it embraces the contrary, all variants and application remaining within the scope of the claims that follow. For example, the shapes of the various lights and guide grooves are not necessarily rectilinear.
