Description
<B><U>DISPOSITIF DE PROTECTION DES OCCUPANTS</U></B> <B><U>SUR PARE-BRISE DE CABRIOLET.</U></B> L'invention concerne le domaine des dispositifs de protection anti choc des passagers avant d'un véhicule automobile. The present invention relates to the field of protective devices. </ Div> anti shock front passengers of a motor vehicle.
L'invention a trait plus spécialement à un dispositif de protection de tête des passagers avant d'un véhicule de type cabriolet. The invention relates more specifically to a front passenger head protection device of a cabriolet type vehicle.
Du document DE 43<B>01</B> 175, on connaît un système sac gonflable qui se déploie sous forme de boudins d'axe horizontal et juxtaposé le long des glaces latérales. From DE 43 <B> 01 </ B> 175, there is known an inflatable bag system which deploys in the form of horizontal axis rolls and juxtaposed along the side windows.
Pour les véhicules de type cabriolet décrit par exemple le document EP 411 448, on connaît un système de protection des occupants au retournement tels que ceux comportant deux arceaux de sécurité qui peuvent rapidement se déployer dans la direction transversale du véhicule. For vehicles of the convertible type described for example in EP 411 448, there is known a system for protecting the occupants of the rollover such as those having two rollbars that can quickly deploy in the transverse direction of the vehicle.
un tel système il n'est pas prévu de dispositif de protection de la tête des occupants en cas de choc. such a system there is no provision for protection of the head of the occupants in case of shock.
Le document US 5 362 097 décrit par ailleurs, un dispositif de protection de la tête des occupants d'un véhicule automobile de type coussin gonflable (airbag) monté dans une zone située entre un élément de structure du toit et un montant de porte du véhicule automobile. Document US Pat. No. 5,362,097 furthermore describes a device for protecting the head of the occupants of an airbag-type motor vehicle mounted in an area located between a roof structure element and a vehicle door pillar. automobile.
En outre, le document EP 900 704 concerne un dispositif de sac gonflable se dépoyant sous le pavillon de toit d'un véhicule classique en vue de protéger la tête des occupants. De tels dispositifs ne s'applique à l'évidence aux véhicules de type cabriolet. In addition, the document EP 900 704 relates to an airbag device lying under the roof of a conventional vehicle to protect the head of the occupants. Such devices obviously apply to vehicles of the cabriolet type.
En effet, en particulier lors d'un choc frontal, pour les occupants des places avant d'un véhicule type cabriolet, lorsqu'ils roulent en position découverte, les risques de heurter le pare-brise sont importants. Leur tête, projetée vers l'avant par la violence du choc, vient inévitablement en collision avec la traverse de pare-brise. Indeed, especially during a frontal impact, for the occupants of the front seats of a convertible type vehicle, when driving in the open position, the risk of striking the windshield is significant. Their head, projected forward by the violence of the shock, inevitably collides with the windshield crossbar.
Par ailleurs, les moyens de retenue dont disposent habituellement les véhicules automobiles modernes, comme des ceintures à prétensionneurs, un coussin gonflable dans le volant, par exemple, ne permettent malheureusement pas d'éviter un tel impact. Moreover, the retaining means usually available in modern motor vehicles, such as pretensioner belts, an airbag in the steering wheel, for example, unfortunately do not allow to avoid such an impact.
Au vu de l'art antérieur, il existe donc encore le besoin d'un dispositif de protection de la tête des passagers avant d'un cabriolet. In view of the prior art, there is still the need for a device for protecting the head of passengers before a convertible.
Aussi un objectif de la présente invention est de satisfaire un tel besoin. En conséquence l'invention a trait à un élément de structure de caisse d'un véhicule automobile de type cabriolet comportant un pare-brise avant comprenant au moins un élément horizontal et transversal superieur agencé dans la partie supérieure de la vitre dans région située sensiblement au niveau de la tête d'un occupant dudit véhicule caractérisé en ce que l'élément comporte des moyens d'amortissement d'un choc de la tête de l'occupant. Also an object of the present invention is to satisfy such a need. Accordingly, the invention relates to a body structure element of a cabriolet type motor vehicle comprising a front windshield comprising at least one horizontal and transverse upper element arranged in the upper part of the window in a region located substantially at level of the head of an occupant of said vehicle characterized in that the element comprises damping means of a shock of the head of the occupant.

The element according to the invention while satisfying a felt need, has among other advantages those to be both effective in the head protection of the occupants before a cabriolet-type vehicle and simple to achieve. According to other complementary or alternative features of the present invention the element comprises a windshield upper crossbar surrounded by a lining which delimits at least one cavity; - The shock absorption means are arranged in the cavity; - the cavity is part of the cross; - The shock absorption means are constituted by less than an airbag; the lining comprises at least one passage facing the head of the occupant intended to allow the passage of at least one airbag in the safety position; the airbag is adapted to deploy in a longitudinal direction inclined towards the head of the occupant; the means for absorbing a shock consist of at least one foam cake; - The lining comprises a flexible portion located in a region facing the head of the occupant; at least one inflatable airbag is provided in association with at least one foam roll arranged transversely along the element; - the cavities are equipped with foam bread between the airbag cartridges; - It provides means for preventing the deployment of the airbag when the convertible top, when rolling in undiscovered position; Foam rolls are made of low density plastic materials such as for example polypropylene foams.
Certaines caractéristiques de la présente invention vont maintenant être décrites de manière plus détaillée à l'aide dessins annexés donnés à titre illustratif et non limitatif et dans lesquels - la Figure 1 est une représentation schématique, d'un élément de structure de caisse conforme à l'invention; - la Figure 2 est une représentation schématique, élément de structure de caisse conforme à l'invention, comportant un pain de mousse<B>;</B> et - la Figure 3 montre le déploiement d'un coussin de sécurite gonflable à partir d'un élément de structure de caisse conforme à l'invention. Certain features of the present invention will now be described in more detail with the aid of the accompanying drawings given for illustrative and non-limiting purposes and in which - Figure 1 is a diagrammatic representation of a body structure element according to the invention. 'invention; FIG. 2 is a schematic representation of the body structure element according to the invention, comprising a foam pad <B>; and FIG. 3 shows the deployment of an inflatable safety pad from a body structure element according to the invention.
Comme illustré à la Figure 1, conformément à la présente invention, l'élément de structure de caisse d'un véhicule automobile de type cabriolet comporte un pare-brise avant 10 comprenant au moins un élément horizontal et transversal supérieur 12 agencé dans la partie supérieure de la vitre dans une région située sensiblement au niveau de la tête d'un occupant dudit vehicule. As illustrated in FIG. 1, in accordance with the present invention, the body structure element of a convertible-type motor vehicle comprises a front windshield 10 comprising at least one upper horizontal and transverse element 12 arranged in the upper part. of the window in a region substantially at the level of the head of an occupant of said vehicle.
Ledit élément 12 comporte une traverse supérieure de pare brise 1 entourée d'un garnissage 18 qui délimite au moins une cavité Des moyens d'ammortissement 14 d'un choc sont agencés dans cavité et sont constitués par un coussin de sécurité gonflable représenté en position déployée hors de sa cartouche rangement. Said element 12 comprises an upper windscreen cross member 1 surrounded by a lining 18 which delimits at least one cavity. A shock absorbing means 14 is arranged in a cavity and is constituted by an airbag represented in the deployed position. out of its storage cartridge.
Dans mode de réalisation de l'élément conforme à l'invention, est prévu un système de gonflage et des moyens de commande gonflage non représentés car de type connu. Le système gonflage du sac de sécurité peut être constitué, par exemple, une réserve de gaz sous pression ou un système pyrotechnique classique. Les moyens de commande de gonflage du sac de sécurite comprennent de préférence un capteur de choc émettant un signal en cas choc tel qu'un accéléromètre et un calculateur recevant un tel signal et apte à émettre un ordre de gonflage en direction sytème gonflage du sac de sécurité. In embodiment of the element according to the invention, there is provided an inflation system and inflation control means not shown because of known type. The inflation system of the security bag may consist, for example, of a pressurized gas supply or a conventional pyrotechnic system. The security bag inflating control means preferably comprise a shock sensor emitting a signal in the event of an impact such as an accelerometer and a computer receiving such a signal and able to issue an inflation command in the direction of the bag inflation system. security.
Le garnissage 18 comporte au moins un passage 24 ou une partie à section réduite pour permettre la rupture du garnissage regard de la tête de l'occupant destiné à permettre le passage d'au moins un coussin gonflable 22 en position de sécurité. The lining 18 comprises at least one passage 24 or a portion of reduced section to allow the rupture of the facing lining of the head of the occupant intended to allow the passage of at least one airbag 22 in the safety position.
La direction longitudinale de déploiement du sac de sécurité gonflable 22 est inclinée vers la tête de l'occupant selon la flèche F. Ainsi, lors d'un choc (Figure 3), tête de l'occupant ne vient plus heurter violemment la traverse supérieure de pare-brise qui est réalisé habituellement en un matériau très rigide. Gràce à l'élément conforme à l'invention, sont évitées les conséquences très graves pour les occupants avant du cabriolet car l'impact a alors lieu sur le coussin gonflable déployé et amorti par déformation de ce dernier. The longitudinal direction of deployment of the airbag 22 is inclined towards the head of the occupant according to the arrow F. Thus, during an impact (Figure 3), the head of the occupant does not come up against the upper crossbar violently windshield which is usually made of a very rigid material. Thanks to the element according to the invention, the consequences are very serious for the front occupants of the convertible because the impact is then on the inflated airbag and cushioned by deformation of the latter.
La Figure 2 illustre une variante de l'élément conforme à l'invention dans laquelle les moyens d'absorption sont constitués d'un pain de mousse 26 en lieu et place d'un sac de sécurité gonflable. Figure 2 illustrates a variant of the element according to the invention wherein the absorption means consist of a foam roll 26 instead of an inflatable bag.
Dans cette variante, le garnissage comporte de préférence une partie souple située dans une région 28 tournée vers la tête de l'occupant. In this variant, the lining preferably comprises a flexible portion located in a region 28 facing the head of the occupant.
Bien entendu les deux représentations ci-dessus de l'élément de l'invention sont données dans un but purement illustratif et non limitatif et des modifications ultérieures pourront être apportées par l'homme du métier sans pour autant sortir du cadre de la présente invention.Of course the two above representations of the element of the invention are given for a purely illustrative and non-limiting purpose and further modifications may be made by those skilled in the art without departing from the scope of the present invention.
