Description

Boucle d'attache des sangles d'un harnais de sécurité équipant un siège pour enfant dans un véhicule automobile Buckle for fastening the straps of a safety harness fitted to a child seat in a motor vehicle
La présente invention concerne une boucle d'attache des sangles d'un harnais de sécurité équipant un siège pour enfant dans un véhicule automobile. L'invention s'intéresse en particulier aux moyens de déverrouillage d'une telle boucle d'attache.The present invention relates to a buckle for attaching the straps of a safety harness fitted to a child seat in a motor vehicle. The invention is particularly concerned with the means for unlocking such an attachment loop.
Dans les boucles d'attache connues, le déverrouillage est réalisé au moyen d'un organe mobile, lequel peut être actionné depuis l'extérieur par un bouton de déverrouillage, une clé de déblocage, ou par un dispositif requérant une séquence d'au moins deux opérations. Ces solutions connues sont soit trop faciles à utiliser par un enfant en bas âge et posent alors un problème de sécurité, soit trop complexes à mettre en œuvre et manquent alors de praticité.In the known fastening loops, the unlocking is carried out by means of a movable member, which can be actuated from the outside by an unlocking button, an unlocking key, or by a device requiring a sequence of at least two operations. These known solutions are either too easy to use by a toddler and pose a security problem, too complex to implement and lack practicality.
La présenté invention vise à éviter ces inconvénients en proposant une boucle d'attache qui soit simple à déverrouiller pour un adulte tout en demeurant difficile à déverrouiller pour un enfant en bas âge.The present invention aims to avoid these disadvantages by providing a fastening loop that is simple to unlock for an adult while remaining difficult to unlock for a toddler.
A cet effet, l'invention a pour objet une boucle d'attache des sangles d'un harnais de sécurité équipant un siège pour enfant dans un véhicule automobile, comportant un fermoir lié de façon permanente à une sangle d'entrejambes et dans lequel s'engagent et se chevauchent deux platines chacune liée à une sangle ventrale et présentant un perçage transversal, les perçages des deux platines venant en regard l'un de l'autre à l'intérieur du fermoir de manière à former une gâche dans laquelle s'engage un verrou, déplaçable en translation perpendiculairement à l'axe d'attache des sangles et actionné vers la position verrouillée par un ressort, le verrou présentant de chaque côté au moins une rampe d'appui latérale d'inclinaison ascendante de la périphérie vers le milieu du verrou, le fermoir comportant en vis-à-vis deux boutons-poussoirs latéraux déplaçables en translation perpendiculairement à l'axe d'attache et au déplacement du verrou, chacun rappelé par un ressort latéral et lié à au moins un doigt de déverrouillage susceptible de venir en appui sur une rampe d'appui latérale correspondante du verrou de manière à provoquer un retrait du verrou hors de la gâche formée par les platines.For this purpose, the subject of the invention is a buckle for fastening the straps of a safety harness fitted to a child seat in a motor vehicle, comprising a clasp permanently connected to a crotch strap and in which s 'engage and overlap two plates each connected to a ventral strap and having a transverse bore, the holes of the two plates facing each other inside the clasp so as to form a strike in which s' engages a latch, movable in translation perpendicular to the axis of attachment of the straps and actuated to the locked position by a spring, the latch having on each side at least one lateral ramp of inclination upward from the periphery to the middle of the lock, the clasp having vis-à-vis two lateral push buttons movable in translation perpendicular to the axis of attachment and the movement of the lock, each recalled by a lateral spring and connected to at least one unlocking finger may bear against a corresponding lateral support ramp of the lock so as to cause a withdrawal of the lock out of the striker formed by the plates.
Ainsi, le déverrouillage de la boucle d'attache selon l'invention est réalisé en exerçant une pression simultanée sur deux boutons-poussoirs latéraux du fermoir, lequels comportent des doigts de déverrouillage qui poussent sur des rampes d'appui latérales du verrou de manière à faire reculer le verrou hors de la gâche formée par les platines. Les facultés de coordination motrice requises pour effectuer ce geste ne s'acquièrent qu'à un certain âge de sorte qu'un enfant en bas âge ne pourra pas ouvrir facilement son harnais tandis que cette opération sera très facile et rapide à effectuer pour un adulte ou un enfant plus âgé.Thus, the unlocking of the fastening buckle according to the invention is achieved by exerting a simultaneous pressure on two lateral buttons of the clasp, which include unlocking fingers which push on lateral support ramps of the lock so as to move the lock back out of the lock formed by the plates. The motor coordination faculties required to perform this gesture are only acquired at a certain age so that a toddler will not be able to easily open his harness while this operation will be very easy and quick to perform for an adult or an older child.
Dans une forme de réalisation possible, deux paires de rampes d'appui latérales en vis-à-vis sont ménagées de part et d'autre, relativement à l'axe d'attache, du verrou. Selon un autre aspect complémentaire, le fermoir comporte une lumière en regard de laquelle apparaît un témoin de verrouillage / déverrouillage, de couleur avantageusement vive, prévu pour signaler un état de verrouillage ou de déverrouillage de la boucle d'attache.In one possible embodiment, two pairs of lateral support ramps facing each other are formed on each side, relative to the axis of attachment, of the lock. According to another complementary aspect, the clasp comprises a light opposite which appears a lock / unlock indicator, color advantageously bright, provided to indicate a locking or unlocking state of the fastening loop.
Dans un mode de réalisation envisageable, le témoin de verrouillage / déverrouillage est solidaire d'une pièce formant butée élastique pour les platines, la pièce formant butée élastique étant déplaçable selon l'axe d'attache, et rappelée par un ressort, entre une position de butée contre les platines et une position d'éjection des platines dans laquelle la gâche formée par les platines est hors de portée du verrou. De toute façon l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cette boucle d'attache.In one possible embodiment, the locking / unlocking indicator is integral with a piece forming an elastic abutment for the plates, the piece forming a resilient abutment being movable along the attachment axis, and biased by a spring, between a position stop against the plates and a platinum ejection position in which the striker formed by the plates is out of range of the lock. 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 example, an embodiment of this attachment loop.
Figure 1 est une vue d'ensemble en perspective d'une boucle d'attache conforme à la présente invention. Figure 2 est une vue de dessus en éclaté de la boucle d'attache de la figure 1.Figure 1 is an overall perspective view of an attachment loop according to the present invention. Figure 2 is an exploded top view of the fastening loop of Figure 1.
Figure 3 est une vue de dessus en écorché de la même boucle d'attache.Figure 3 is a top view in cutaway of the same attachment loop.
Figure 4 est une vue en coupe selon IV-IV de la figure 3. Figure 5 est une vue analogue à la figure 4 dans une autre position de fonctionnement de la boucle d'attache.Figure 4 is a sectional view along line IV-IV of Figure 3. Figure 5 is a view similar to Figure 4 in another operating position of the fastening loop.
Figure 6 est une vue en coupe selon Vl-Vl de la figure 3.Figure 6 is a sectional view according to VI-VI of Figure 3.
Figure 7 est une vue analogue à la figure 6 dans la même position de fonctionnement qu'en figure 5. La boucle d'attache des sangles 2, 5 et 6 d'un harnais de sécurité équipant un siège pour enfant dans un véhicule automobile, représentée en figure 1 , comporte un fermoir 1 en partie inférieure duquel est ménagée une fente 1 b prévue pour recevoir une sangle d'entrejambes 2.FIG. 7 is a view similar to FIG. 6 in the same operating position as in FIG. 5. The buckle for fastening the straps 2, 5 and 6 of a safety harness fitted to a child seat in a motor vehicle, represented in 1 comprises a clasp 1 in the lower part of which is provided a slot 1b provided to receive a crotch strap 2.
Deux platines 3 et 4 sont liées, par leurs parties supérieures 3a et 4a, à des sangles ventrales, gauche 5 et droite 6. Les parties inférieures 3b et 4b des platines 3 et 4 (voir figure 2) sont prévues pour s'engager au travers d'une ouverture 1a en partie supérieure (relativement à l'axe longitudinal A d'attache des sangles 5, 6 et 2) du fermoir 1 , et conformées pour se chevaucher, à l'intérieur du fermoir 1.Two plates 3 and 4 are connected, by their upper parts 3a and 4a, to ventral straps, left 5 and right 6. The lower parts 3b and 4b of the plates 3 and 4 (see Figure 2) are provided to engage at through an opening 1a in the upper part (relative to the longitudinal axis A of fastening of the straps 5, 6 and 2) of the clasp 1, and shaped to overlap, inside the clasp 1.
Dans un souci d'ergonomie, l'une au moins des platines 3, 4 est légèrement vrillée à la jonction entre sa partie supérieure 3a, 3b et sa partie inférieure 3b, 4b de manière à ce que les parties supérieures 3a et 3b des platines 3, 4 soient coplanaires.For the sake of ergonomics, at least one of the plates 3, 4 is slightly twisted at the junction between its upper part 3a, 3b and its lower part 3b, 4b so that the upper parts 3a and 3b of the plates 3, 4 are coplanar.
Le fermoir 1 comporte en outre deux boutons-poussoirs latéraux 7 et 8 en vis-à-vis, qui permettent le déverrouillage de la boucle d'attache. Une lumière 1c du fermoir 1 fait apparaître un témoin 9 de couleur avantageusement vive signalant le verrouillage ou le déverrouillage de la boucle d'attache.The clasp 1 further comprises two lateral pushbuttons 7 and 8 vis-à-vis, which allow the unlocking of the fastening loop. A light 1c of the clasp 1 shows an indicator 9 of advantageously bright color signaling the locking or unlocking of the fastening loop.
Comme le montre mieux la figure 2, les platines 3 et 4 comportent sur leurs parties inférieures 3b et 4b, des perçages 3c et 4c destinées à venir en regard l'une de l'autre à l'intérieur du fermoir 1 de manière à former une gâche.As best shown in Figure 2, the plates 3 and 4 have on their lower parts 3b and 4b, bores 3c and 4c intended to come facing one another inside the clasp 1 so as to form a strike.
Le fermoir 1 comporte une demi-coque intérieure 10 plane, prévue pour être appliquée contre le ventre de l'enfant, et une demi-coque extérieure 11 destinée à être fixée contre Ia demi-coque intérieure 10. La face interne de la demi-coque extérieure 11 est représentée en figure 3. Elle comporte deux parois longitudinales 11a et 11 b (par rapport à l'axe A) contre chacune desquelles prennent appui deux ressorts 12, 13 et 14, 15 de rappel pour chaque bouton-poussoir 7 et 8.The clasp 1 comprises a flat inner half-shell 10, intended to be applied against the child's belly, and an outer half-shell 11 intended to be fixed against the inner half-shell 10. The inner face of the half-shell outer shell 11 is shown in Figure 3. It has two longitudinal walls 11a and 11b (relative to the axis A) against which each support two springs 12, 13 and 14, 15 for each push button 7 and 8.
Entre les parois longitudinales 11a et 11 b, deux parois transversales 11c et 11d délimitent une cavité centrale 16 et une cavité inférieure 17.Between the longitudinal walls 11a and 11b, two transverse walls 11c and 11d delimit a central cavity 16 and a lower cavity 17.
Chaque bouton poussoir 7, 8 comporte deux doigts 7a, 7b et 8a, 8b de déverrouillage agissant sur un verrou 18 logé dans la cavité centrale 16. Le témoin 9 de verrouillage / déverrouillage est logé dans la cavité inférieure 17 au niveau de laquelle est ménagée la lumière 1c. Le verrou 18 et le témoin 9 de verrouillage / déverrouillage sont représentés plus particulièrement sur les figures 4 à 7.Each push button 7, 8 comprises two unlocking fingers 7a, 7b and 8a, 8b acting on a latch 18 housed in the central cavity 16. The 9 locking / unlocking indicator is housed in the lower cavity 17 at which is provided the light 1c. The latch 18 and the indicator 9 locking / unlocking are shown more particularly in Figures 4 to 7.
Le verrou 18 est une pièce de forme générale rectangulaire correspondant à la cavité centrale 16, et déplaçable en translation, perpendiculairement à l'axe A. Un ressort 19, de rappel du verrou 18 vers la position verrouillée, est monté en appui contre le fond de la cavité centrale 16.The latch 18 is a piece of generally rectangular shape corresponding to the central cavity 16, and displaceable in translation, perpendicular to the axis A. A spring 19, for returning the latch 18 to the locked position, is mounted in abutment against the bottom of the central cavity 16.
Le verrou 18 comporte en partie supérieure, à l'opposé du ressort 19, une portion centrale saillante 18a formant pêne susceptible de s'engager dans la gâche (les perçages 3c et 4c) formée par les platines 3 et 4 en chevauchement dans le fermoir 1.The latch 18 comprises in the upper part, opposite the spring 19, a projecting central portion 18a forming a bolt capable of engaging in the keeper (the holes 3c and 4c) formed by the plates 3 and 4 overlapping in the clasp 1.
Le témoin 9 de verrouillage / déverrouillage est réalisée sous la forme d'une pièce de forme générale rectangulaire logée dans la cavité inférieure 17, et surmontée et solidaire d'une pièce saillante 9a hors de la cavité 17 et formant une butée élastique pour les extrémités des platines 3, 4. La pièce saillante 9a formant butée élastique est rappelée par un ressort 20, et déplaçable en translation selon l'axe A, entre une position de butée contre les extrémités des platines 3, 4, lorsque la boucle d'attache est verrouillée (voir figure 4), et une position de butée du témoin 9 contre la paroi transversale 11d de la cavité inférieure 17, lorsque la boucle d'attache est déverrouillée (voir figure 5).The locking / unlocking indicator 9 is in the form of a piece of generally rectangular shape housed in the lower cavity 17, and surmounted and secured to a projecting piece 9a outside the cavity 17 and forming an elastic stop for the ends plates 3, 4. The protruding piece 9a forming elastic stop is biased by a spring 20, and displaceable in translation along the axis A, between an abutment position against the ends of the plates 3, 4, when the fastening loop is locked (see Figure 4), and a stop position of the control 9 against the transverse wall 11d of the lower cavity 17, when the fastening loop is unlocked (see Figure 5).
La pièce saillante 9a formant butée élastique permet de faciliter le retrait des platines 3, 4 hors du fermoir 1 en éjectant les platines 3, 4 lors du déverrouillage de manière à ce que les ouvertures transversales 3c et 4c des platines 3, 4 ne soient plus accessibles au verrou 18. Le témoin 9 comporte deux zones distinctes colorées, par exemple l'une en rouge et l'autre en vert, espacées axiaiement, l'une ou l'autre pouvant venir en regard de la lumière 1c du fermoir 1 afin de signaler, respectivement, que la boucle est déverrouillée ou verrouillée, selon que la pièce saillante 9a est ou non en butée contre les extrémités des platines 3, 4. Comme le montrent mieux les figures 6 et 7, deux paires de rampes d'appui latérales 21a, 21 b et 22a, 22b sont ménagées sur le verrou 18, de part et d'autre (relativement à l'axe A) de la portion centrale saillante 18a formant pêne. Les rampes d'appui latérales 21a, 21 b et 22a, 22b présentent une inclinaison ascendante depuis la périphérie jusqu'au milieu du verrou 18. Une pression conjuguée des deux boutons-poussoirs 7 et 8 permet d'actionner les doigts de déverrouillage 7a, 7b et 8a, 8b qui exercent alors une poussée vers le milieu du verrou 18, perpendiculairement à l'axe A et au déplacement du verrou 18, sur les rampes d'appui latérales 21a, 21b et 22a,The projecting piece 9a forming an elastic stop facilitates the withdrawal of the plates 3, 4 from the clasp 1 by ejecting the plates 3, 4 during unlocking so that the transverse openings 3c and 4c of the plates 3, 4 are no longer accessible to the latch 18. The indicator 9 has two distinct colored areas, for example one in red and the other in green, spaced axially, one or the other may come opposite the light 1c of the clasp 1 so to indicate, respectively, that the loop is unlocked or locked, depending on whether the projecting piece 9a is or not abutting against the ends of the plates 3, 4. As best shown in Figures 6 and 7, two pairs of support ramps 21a, 21b and 22a, 22b are provided on the latch 18, on both sides (relative to the axis A) of the projecting central portion 18a forming a bolt. The lateral bearing ramps 21a, 21b and 22a, 22b have an upward inclination from the periphery to the middle of the latch 18. A combined pressure of the two pushbuttons 7 and 8 makes it possible to actuate the unlocking fingers 7a, 7b and 8a, 8b which exercise then a pushing towards the middle of the latch 18, perpendicular to the axis A and the displacement of the latch 18, on the lateral bearing ramps 21a, 21b and 22a,
22b (voir figure 6).22b (see Figure 6).
Du fait de l'inclinaison, ascendante vers le milieu du verrou 18, des rampes 21a, 21b et 22a, 22b, le verrou 18 recule dans la cavité centrale 16 et comprime le ressort 19 contre le fond de la cavité 16 (voir figure 7). La boucle d'attache est déverrouillée lorsque la portion centrale saillante 18a formant pêne ne retient plus les platines 3 et 4 dans le fermoir 1.Due to the inclination, upwards towards the middle of the latch 18, ramps 21a, 21b and 22a, 22b, the latch 18 moves back into the central cavity 16 and compresses the spring 19 against the bottom of the cavity 16 (see FIG. ). The fastening loop is unlocked when the projecting central portion 18a forming a bolt no longer holds the plates 3 and 4 in the clasp 1.
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cette boucle d'attache, qui a été décrite ci-dessus à titre d'exemple ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe. It goes without saying that the invention is not limited to the sole embodiment of this attachment loop, which has been described above as an example; it embraces, on the contrary, all variants of implementation and application respecting the same principle.
