Description

2883813 DESCRIPTIF2883813 DESCRIPTION

Les enfants transportés à bord des véhicules sont, en cas de collision, soumis à des phénomènes de décélérations brutales qui génèrent sur leur corps des forces de retenue de grande intensité.  In the event of a collision, children transported in vehicles are subject to sudden decelerations that generate high-intensity restraining forces on their bodies.

La protection de ces jeunes passagers de tailles réduites ne peut se faire sans l'utilisation de Dispositifs de Retenue pour Enfants appelés par les spécialistes en Sécurité, DRE, en adéquation avec leur taille et leur poids conformément à l'article R.351 du Code de la Route. Cette contrainte est due au fait que l'habitacle du véhicule et ses sièges sont dimensionnés pour les adultes, et que, de surcroît, les ancrages des ceintures de sécurité sont positionnés pour les dits adultes.  The protection of these small sized passengers can not be achieved without the use of Child Restraint Systems called by Safety Specialists, DRE, in accordance with their size and weight in accordance with Article R.351 of the Code. of the road. This constraint is due to the fact that the cabin of the vehicle and its seats are sized for adults, and that, moreover, the anchorages of the seatbelts are positioned for said adults.

De plus, les systèmes additionnels tels que prétensionneurs et limiteurs d'efforts de sangles et autres sacs gonflables, frontaux et latéraux, sont également localisés et surtout calibrés pour une protection optimisée d'un être humain de taille adulte, de sorte qu'ils constituent plutôt un risque d'être plus ou moins grièvement blessés pour ceux de taille plus réduite.  In addition, the additional systems such as pretensioners and force limiters of straps and other airbags, front and side, are also located and especially calibrated for optimized protection of an adult sized human, so that they constitute rather a risk of being more or less seriously injured for those of smaller size.

A ces problèmes d'ordre technique, viennent s'ajouter des difficultés liées à des vulnérabilités spécifiques des enfants dues principalement à la fragilité de l'empilage cervical qui doit inévitablement supporter les efforts de retenue de la tête en cours de choc; à la forme inachevée des parties antérieures des ailes iliaques du pelvis qui ne peut assurer un appui stable de la sangle sous abdominale, facilitant ainsi un glissement de cette dernière vers la cavité abdominale suivi d' une pénétration profonde souvent responsable de lésions des viscères, souvent graves et difficilement décelables au premier abord. Pour limiter le risque de blessures à l'abdomen consécutives à un basculement du bassin sous la sangle, il convient de placer l'enfant sur un DRE dit rehausseur ou coussin rehausseur qui peut être pourvu ou non d'un dosseret. La fonction essentielle de ce dispositif est de surélever le bassin de l'enfant en augmentant l'angle (1 planche 1/14 figure 1/18) . En cas de collision et d'efforts de retenue élevés, le bassin aura ainsi plutôt tendance à remonter sur la sangle qui s'incrustera et s'appuiera sur l'os du pelvis au pli de l'haine, Cependant, malgré cette amélioration, de nombreux enfants souffrent ou 35 décèdent suite à des blessures à l'abdomen du fait que la sangle est en mauvaise position ou en position dangereuse lorsque, comme observé 2883813 2 fréquemment, le jeune occupant qui se ceinture seul, fait passer le brin pelvien sur les accoudoirs du rehausseur.  To these technical problems, are added difficulties related to specific vulnerabilities of children due mainly to the fragility of the cervical stack which must inevitably withstand the efforts of retaining the head during shock; to the unfinished form of the anterior parts of the pelvic iliac wings which can not provide a stable support of the abdominal strap, thus facilitating a sliding of the latter towards the abdominal cavity followed by a deep penetration often responsible for lesions of the viscera, often severe and difficult to detect at first sight. To limit the risk of injury to the abdomen following a tilting of the pelvis under the strap, it is appropriate to place the child on a DRE said enhancer or booster cushion that may or may not be equipped with a back splash. The essential function of this device is to raise the pelvis of the child by increasing the angle (1 plate 1/14 figure 1/18). In the event of a collision and high restraint efforts, the pelvis will tend to rise on the strap that will incrusta and rely on the pelvic bone in the fold of hate, However, despite this improvement, many children suffer or die from injuries to the abdomen because the strap is in the wrong or dangerous position when, as observed frequently, the young occupant who is seated alone, passes the pelvic strand on the armrests of the booster seat.

C'est de ce constat qu'est né le concept d'un rehausseur de haute sécurité.  This is what led to the concept of a high security booster.

Ce dispositif présente l'avantage d'exploiter l'existence des barres d'ancrage (25 planche 14/14 figure 18/18) standardisées pour DRE dites ISOFIX dont sont dotés tous les véhicules récents.  This device has the advantage of exploiting the existence of the anchor bars (25 board 14/14 figure 18/18) standardized for DRE called ISOFIX which are equipped with all recent vehicles.

Ce dispositif peut être ainsi assujetti facilement, de façon rigide ou semi rigide au plancher du véhicule ou à l'ossature tubulaire rigide de la banquette, cette liaison présentant plusieurs avantages incontestable: elle permet de s'affranchir du rajout des accoudoirs des rehausseurs traditionnels. Ces appendices ont pour fonction première d'empêcher le glissement du rehausseur sous les fessiers de l'enfant pendant le choc. En supprimant les accoudoirs, on éradique le risque de positionnement extrêmement dangereux des brins de la ceinture de sécurité sur ces derniers au niveau du plexus de l'enfant.  This device can thus be easily secured rigidly or semi-rigidly to the floor of the vehicle or to the rigid tubular frame of the seat, this connection having several undeniable advantages: it eliminates the addition of armrests traditional boosters. These appendages have the primary function of preventing the booster from sliding under the glutes of the child during the shock. By removing the armrests, we eradicates the risk of extremely dangerous positioning of the strands of the seat belt on the latter at the plexus of the child.

L'accrochage du rehausseur aux points d'ancrage ISOFIX permet de faire bénéficier l'enfant d'un système de protection abdominale mis au point pour l'adulte et communément utilisé sur tous les véhicules modernes: la rame anti sous-marinage (11 planche 7/14 figure 9/18) (12 rampe J J planche 8/14 figure 10/18) . Il s'agit dans ce cas, d'un dispositif simple, constitué d'une forme en tôle emboutie associée au plancher ou à l'assise de banquette, permettant l'appui des ischions du bassin au début du processus de retenue. Ce calage des pointes inférieures de l'os pelvien empêche sa rotation, prévenant ainsi tout risque de sous-marinage. De plus, les efforts supportés par les os ischions, se soustraient aux forces appliquées par la sangle sous abdominale sur la partie supérieure du pelvis et/ou l'abdomen.  Attaching the booster seat to the ISOFIX anchorage points allows the child to benefit from an abdominal protection system developed for adults and commonly used on all modern vehicles: the anti-submarine train (11 board 7/14 Figure 9/18) (12 ramp JJ Plate 8/14 Figure 10/18). In this case, it is a simple device consisting of a stamped sheet metal form associated with the floor or the seat base, allowing the support of the ischium basin at the beginning of the process of restraint. This wedging of the lower points of the pelvic bone prevents its rotation, thus preventing any risk of submarining. In addition, the forces supported by the ischial bones, are evading the forces applied by the sub-abdominal strap on the upper part of the pelvis and / or the abdomen.

Dans le cas du rehausseur ou de siège faisant l'ob jet de la présente demande de brevet d'invention, la rampe d'appui (8 planche 4/14 figure 4/18) (13 planche 9/14 figure 11/18) est intégrée à la coque et sa fonction protectrice peut être réalisée grâce à l'assujettissement du dispositif aux structures rigides du véhicule et à la compression de la mousse ou/et de poches gonflables qui comblent la cavité (9 planche 4/14 figure 4/18) , ménagée dans le rehausseur ou le siège.  In the case of the booster or seat subject of the present invention patent application, the support ramp (8 board 4/14 figure 4/18) (13 board 9/14 figure 11/18) is integrated into the hull and its protective function can be achieved by securing the device to the rigid structures of the vehicle and the compression of the foam and / or inflatable pockets that fill the cavity (9 plate 4/14 figure 4 / 18) in the booster seat or seat.

Avantageusement le rehausseur ou siège est installé à demeure sur la banquette du véhicule, empêchant l'enfant de l'écarter sous prétexte qu'il est grand et que son emploi est superflu, comportement avéré suite à de nombreuses enquêtes d'usage réel.  Advantageously, the booster seat or seat is permanently installed on the seat of the vehicle, preventing the child to dismiss it on the grounds that it is large and that its use is superfluous, proven behavior following many investigations of actual use.

2883813 3 Un système détectant la présence de l'enfant sur le rehausseur et déclenchant un signal sonore temporisé complètera ses fonctions sécuritaires en remémorant à l'enfant, au conducteur et passagers que la ceinture de sécurité doit être bouclée.  2883813 3 A system that detects the presence of the child on the booster seat and triggers a delayed beeper will complete its safety functions by reminding the child, driver and passengers that the seat belt needs to be buckled.

Avantageusement le dispositif, rehausseur ou siège semble pouvoir grandement diminuer le risque de lésions abdominales chez l'enfant en exploitant de façon simple, donc peut coûteuse, la possibilité d'utilisation des ancrages dits ISOFIX dont sont pourvus tous les véhicules récents. Il fait bénéficier l'enfant d'un principe adopté depuis pratiquement deux décades pour protéger l'adulte des effets dits de sous-marinage . Ce principe a été évalué en laboratoire avant sa commercialisation et a prouvé son efficacité lors d'accidents analysés par les experts. Il apporte de surcroît une solution radicale aux problèmes de positionnements dangereux des sangles de la ceinture de sécurité inhérents à la présence d'accoudoirs proéminents. Il oblige l'enfant à s'asseoir sur le dispositif qui se trouve ainsi installé à demeure sur la banquette et,enf in, rappelle par avertisseur sonore que la place est occupée et que dès lors la ceinture doit être bouclée.  Advantageously, the device, booster or seat seems to greatly reduce the risk of abdominal lesions in children by operating in a simple way, so can expensive, the possibility of use anchors called ISOFIX which are provided with all recent vehicles. It provides the child with a principle adopted for almost two decades to protect the adult so-called submarine effects. This principle was evaluated in the laboratory before its commercialization and proved its effectiveness during accidents analyzed by the experts. It also provides a radical solution to the problem of dangerous positioning of the seat belt straps inherent to the presence of prominent armrests. It forces the child to sit on the device which is thus permanently installed on the bench and, in this case, reminds by buzzer that the place is occupied and that therefore the belt must be buckled.

Ce système, compte tenu de sa simplicité, de son prix de revient industriel modéré, et des avantages sécuritaires qu'il présente, devrait rendre obsolète tout dispositif non directement assujetti à la structure rigide du véhicule ou du siège.  This system, given its simplicity, its moderate industrial cost price, and the security advantages it presents, should render obsolete any device not directly subject to the rigid structure of the vehicle or the seat.

Il est indéniable que le présent dispositif fera diminuer de façon drastique, le nombre d'enfants grièvement atteints à l'abdomen lors d'accidents routiers.  It is undeniable that the present device will drastically reduce the number of children seriously injured in the abdomen in road accidents.

La planche 1/14 figure 1/18 représente un enfant assis directement sur la banquette du véhicule automobile.  The plate 1/14 figure 1/18 represents a child sitting directly on the bench of the motor vehicle.

La planche 2/14 figure 2/18 représente le même enfant pendant une décélération du véhicule. L'enfant s'enfonce dans le siège. Son abdomen est compressé.  Plate 2/14 figure 2/18 represents the same child during a deceleration of the vehicle. The child sinks into the seat. His abdomen is compressed.

La planche 3/14 figure 3/18 représente le même enfant. Sous l'effet de la décélération la sangle, entrée profondément dans l'abdomen (2 planche 3/14 figure 3/18), va écraser la rate, les intestins et endommager gravement la plèvre et la base des poumons.  Plate 3/14 figure 3/18 represents the same child. Under the effect of deceleration the strap, entered deeply into the abdomen (2 plate 3/14 figure 3/18), will crush the spleen, intestines and severely damage the pleura and the base of the lungs.

La planche 4/14 figure 4/18 représente le rehausseur ou l'assise du siège 40 enfant, objet de la présente demande de brevet d'invention. Le dit 15 20 25 2883813 4 rehausseur ou siège est rendu solidaire du véhicule automobile de la façon suivante: Un crochet (3 planche 4/14 figure 4/18) ou mousqueton, ouvert ou fermé, est accroché à la barre d'ancrage (4 planche 4/14 figure 4/18) du véhicule automobile. Le dit croché est relié à une sangle (5 planche 4/14 figure 4/18) à l'aide d'une couture (6 planche 4/14 figure 4/18) industrielle de haute résistance mécanique. La dite sangle traverse un dispositif (7 planche 4/14 figure 4/18) de fermeture-ouverture-blocage à cames, laissant passer librement la sangle lorsque le dispositif est ouvert et empêchant la sangle de se déplacer et glisser lorsque le dispositif est fermé. Le dispositif de fermetureouverture-blocage est relié au rehausseur ou siège dans sa partie inférieure, logé dans une rainure (10 planche 6 figure 7/18) (23 planche 12/14 figure 14/18) allant de l'arrière à l'avant du rehausseur ou siège. La sangle est logée dans la même rainure, cette dernière étant fermée à l'aide d'une plaque (24 planche 13/14 figure 17/18) venant s'encastrer dans le fond du rehausseur ou siège. A titre indicatif et non exhaustif la rainure décrite précédemment peut être remplacée par un canal traversant de part en part la coque du rehausseur ou par un canal débouchant sous le siège afin d'y loger le dispositif de fermeture- ouverture-blocage de la sangle.  The board 4/14 figure 4/18 represents the booster seat or the seat of the child seat 40, subject of the present patent application. The said booster or seat is secured to the motor vehicle as follows: A hook (3 plate 4/14 figure 4/18) or carabiner, open or closed, is attached to the anchor bar ( 4/4 plate 4/18) of the motor vehicle. The said hook is connected to a strap (5 4/14 board figure 4/18) using a seam (6 board 4/14 Figure 4/18) industrial high mechanical strength. The said strap passes through a device (7 plate 4/14 FIG. 4/18) for closing-opening-locking with cams, allowing the strap to pass freely when the device is open and preventing the strap from moving and sliding when the device is closed. . The closure-locking device is connected to the booster or seat in its lower part, housed in a groove (10 board 6 figure 7/18) (23 board 12/14 figure 14/18) going from the back to the front booster seat or seat. The strap is housed in the same groove, the latter being closed by means of a plate (24 plate 13/14 Figure 17/18) coming to fit into the bottom of the booster seat. As an indication and not exhaustive, the groove described above can be replaced by a channel passing right through the shell of the booster or by a channel opening under the seat to accommodate the closure-opening-locking device of the strap.

La planche 5/14 figure 5/18 et 6/18 représente un modèle de crochet ou mousqueton plat pouvant s'accrocher correctement sur la barre d'ancrage du véhicule automobile.A titre indicatif le crochet ou le mousqueton peut être remplacé par une double pince venant serrer et bloquer la sangle.  The board 5/14 figure 5/18 and 6/18 represents a model of hook or carabiner flat being able to hang correctly on the bar of anchorage of the motor vehicle. As an indication the hook or the karabiner can be replaced by a double clamp coming to tighten and lock the strap.

La planche 6/14 figure 7/18 représente le profil avant du rehausseur. On remarque la rainure recevant le dispositif à fermeture-ouvertureblocage et la sangle.  Plate 6/14 Figure 7/18 shows the front profile of the booster. Note the groove receiving the closure-opening device and the strap.

La planche 6/14 figure 8/18 représente une vue de dessous du rehausseur. On remarque les rainures et les plaques de fermeture empêchant la sangle de sortir de son logement.  Plate 6/14 Figure 8/18 shows a bottom view of the booster. We notice the grooves and closing plates preventing the strap out of its housing.

La planche 7/14 figure 9/18 représente une plaque anti sous marinage pour adulte. Cette plaque se déforme lors d'un choc du véhicule.  The plate 7/14 figure 9/18 represents an anti-submarining plate for adults. This plate is deformed during a shock of the vehicle.

2883813 5 La planche 9/14 figure 11/18 représente un enfant assis sur le rehausseur ou assise de siège, ob jet de la présente demande de brevet d'invention. On remarque la plaque anti sous marinage, l'excavation où sont logés le ou les blocs de mousse ou/et les poches gonflées munies de leurs évents. En cas de freinage intempestif ou choc le rehausseur ne se déplacera pas d'arrière en avant ou latéralement ce qui n'est pas le cas des rehausseurs mis sur le marché actuellement. Les rehausseurs actuels du marché, non habillés de tissu ou matière anti dérapante dans leurs parties inférieures, glissent sous l'enfant et sont dangereux, l'enfant étant rarement dans une position de sécurité.  The board 9/14 figure 11/18 shows a child sitting on the booster or seat seat, ob jet of the present patent application. Note the anti-submarining plate, the excavation where are housed or foam blocks or / and inflated pockets with their vents. In the event of inadvertent braking or shock the booster will not move backwards or forwards, which is not the case with the boosters currently on the market. The current market boosters, not dressed in fabric or anti-slip material in their lower parts, slide under the child and are dangerous, the child is rarely in a position of safety.

La planche 10/14 figure 12/18 représente le même enfant. La décélération fait déplacer son corps vers l'avant celui-ci s'enfonçant dans les blocs de mousse et/ou poches gonflées. La sangle pelvienne est dans sa bonne position.  Plate 10/14 Figure 12/18 represents the same child. The deceleration causes the body to move forwards as it sinks into the foam blocks and / or inflated pockets. The pelvic strap is in its good position.

La planche 11/14 figure 13/18 représente l'enfant enfoncé dans les blocs de mousse et/ou poches gonflées munies d'évents. On remarque que la cale anti sous marinage a retenu l'enfant.  Plate 11/14 Figure 13/18 shows the child embedded in the foam blocks and / or inflated pockets provided with vents. It is noted that the anti-submarine hold has retained the child.

ira planche 12/14 figure 14/18 représente une vue avant des blocs de mousse et/ou poches gonflées. La planche 12 figure 15/18 représente une vue arrière des blocs de mousse et/ou poches gonflées. II est possible d'associer blocs de mousse et poches gonflées afin d'obtenir un meilleur résultat en temps et en efficacité de l'affaissement extrèmement rapide du bassin de l'enfant.  12/14 Figure 14/18 shows a front view of the foam blocks and / or inflated pockets. The board 12 figure 15/18 shows a rear view of the foam blocks and / or inflated pockets. It is possible to associate foam blocks and inflated pockets to obtain a better result in time and efficiency of the extremely rapid collapse of the child's pelvis.

A titre d'exemple et non exhaustif la figure 14/18 représente quatre blocs de mousse, le premier (15 planche 12/14 figure 14/18) ayant une densité de vingt kilos, le deuxième (16 planche 12/14 figure 14/18) une densité de vingt kilos, le troisième (17 planche 12/14 figure 14/18) une densité de quarante kilos, le quatrième (18 planche 12/14 figure 14/18) une densité de soixante kilos.  By way of non-exhaustive example, FIG. 14/18 shows four blocks of foam, the first (board 12/14 FIG. 14/18) having a density of twenty kilos, the second (16 board 12/14 FIG. 18) a density of twenty kilos, the third (17 plank 12/14 figure 14/18) a density of forty kilos, the fourth (18 plank 12/14 figure 14/18) a density of sixty kilos.

A titre d'exemple et non exhaustif la figure 15/18 représente quatre poches gonflées dans lesquelles sont insérées des mousses de maintien et de confort pour l'enfant, la première poche (19 planche 12/14 figure 15/18) comportant huit évents, la seconde poche (20 planche 12/14 figure 15/18) comportant six évents, la troisième poche (21 planche 12/14 figure 15/18) comportant quatre évents, la quatrième poche (22 planche 12/14 figure 15/18) comportant deux évents. Le dégonflage programmé des poches calculé en millisecondes permet de rendre plus efficace la retenue du bassin de l'enfant par la cale anti sous marinage, 10 2883813 6 sachant que le siège est solidement ancré aux barres isofix du véhicule automobile.  By way of example and not exhaustive Figure 15/18 shows four inflated pockets in which are inserted foams for maintenance and comfort for the child, the first pocket (19 board 12/14 figure 15/18) having eight vents the second pocket (20/6/15/18) having six vents, the third pocket (21/9/14 figure 15/18) having four vents, the fourth pocket (22/9/14 figure 15/18). ) having two vents.
