DISPOSITIF DE PROTECTION CONTRE L'INTRUSION D'UN PARE- BRISE DANS UNE CABINE DE CONDUITE DE VEHICULE FERROVIAIRE LORS D'UN CHOC L'invention se rapporte au domaine de la construction de véhicules, en particulier de véhicules ferroviaires, et a pour objet un dispositif de protection contre l'intrusion d'un pare-brise dans une cabine de conduite lors d'un choc ainsi qu'un véhicule comportant un tel dispositif de protection. The invention relates to the field of vehicle construction, in particular rail vehicles, and relates to an object of protection of the intrusion of a windshield into a driver's cab of a rail vehicle. protection device against the intrusion of a windshield into a driver's cabin during an impact as well as a vehicle comprising such a protection device.
Il est connu du document FR-A-2 698 840, de réaliser un véhicule ferroviaire comportant un châssis dont les extrémités sont munies de zones de déformation plastique dynamique, formées d'éléments absorbeurs d'énergie fixes ou interchangeables, ayant pour fonction de protéger les passagers et le conducteur du véhicule en cas de chocs importants, par exemple avec un autre train. It is known from document FR-A-2 698 840 to produce a railway vehicle comprising a chassis, the ends of which are provided with dynamic plastic deformation zones, formed of fixed or interchangeable energy absorbing elements, having the function of protecting the passengers and the driver of the vehicle in the event of a major impact, for example with another train.
De tels véhicules comportent habituellement une cabine de conduite munie d'un pare-brise qui est fixé sur une peau réalisant l'enveloppe esthétique du véhicule, permettant ainsi d'avoir une liaison pare-brise/carrosserie possédant une bonne aérodynamique. Toutefois, une telle peau possède une structure qui n'est pas prévue pour résister aux chocs importants, la rigidité du véhicule étant assurée par une structure indépendante, si bien qu'en cas de choc violent avec un obstacle venant briser la peau, le pare-brise est projeté dans la cabine de conduite mettant en danger la vie du conducteur. Such vehicles usually include a driving cabin provided with a windshield which is fixed to a skin forming the aesthetic envelope of the vehicle, thus making it possible to have a windshield / bodywork connection having good aerodynamics. However, such a skin has a structure which is not designed to withstand large shocks, the rigidity of the vehicle being provided by an independent structure, so that in the event of a violent impact with an obstacle breaking the skin, the barrier -brise is thrown into the driver's cabin endangering the life of the driver.
La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de protection contre l'intrusion d'un pare-brise dans une cabine de conduite d'un véhicule ferroviaire lors d'un choc qui soit simple et économique à réaliser. The object of the present invention is to overcome these drawbacks by proposing a device for protection against the intrusion of a windshield into a driving cabin of a railway vehicle during an impact which is simple and economical to produce.
A cet effet, l'invention a pour objet un dispositif de protection contre l'intrusion d'un pare-brise dans une cabine de conduite d'un véhicule ferroviaire lors d'un choc, caractérisé en ce qu'il comporte un bouclier de protection s'interposant entre le parebrise et l'intérieur de la cabine de conduite et étant relié à un élément de structure du véhicule, le bouclier de protection comportant une ouverture, en regard du pare-brise, de surface réduite par rapport à la surface du pare-brise. To this end, the subject of the invention is a device for protecting against the intrusion of a windshield into a driver's cab of a railway vehicle during an impact, characterized in that it comprises a shield protection interposed between the windshield and the interior of the driver's cab and being connected to a structural element of the vehicle, the protective shield comprising an opening, facing the windshield, of reduced surface area compared to the surface of the windshield.

Selon des modes particuliers de réalisation, le dispositif de protection peut comprendre l'une ou plusieurs des caractéristiques suivantes prises isolément ou selon toutes les combinaisons techniquement possibles : - le bouclier de protection s'étend sensiblement sur toute la hauteur de la cabine de conduite ;
- le bouclier de protection est renforcé de manière à être indéformable ; - l'élément de structure supportant le bouclier de protection est le châssis du véhicule ; - le pare-brise du véhicule est supporté par une peau réalisant l'enveloppe esthétique de l'extrémité du véhicule ; L'invention concerne également un véhicule ferroviaire comportant une extrémité munie d'un pare-brise devant une cabine de conduite, caractérisé en ce qu'il comporte un dispositif de protection conforme aux caractéristiques précédemment décrites. According to particular embodiments, the protection device can comprise one or more of the following characteristics taken in isolation or according to all technically possible combinations: - the protection shield extends substantially over the entire height of the driving cabin;
- the protective shield is reinforced so as to be non-deformable; - the structural element supporting the protective shield is the chassis of the vehicle; - The vehicle windshield is supported by a skin providing the aesthetic envelope of the end of the vehicle; The invention also relates to a rail vehicle comprising an end provided with a windshield in front of a driving cabin, characterized in that it comprises a protection device conforming to the characteristics described above.
On comprendra mieux les buts, aspects et avantages de la présente invention, d'après la description donnée ci-après d'un mode de réalisation de l'invention, présenté à titre d'exemple non limitatif, en se référant aux dessins annexés, dans lesquels :
La figure 1 est une vue en coupe longitudinale d'un véhicule ferroviaire équipé d'un dispositif de protection conforme à l'invention ;
La figure 2 est une vue en perspective du dispositif de protection de la figure 1 représenté seul avec le pare-brise du véhicule. The aims, aspects and advantages of the present invention will be better understood from the description given below of an embodiment of the invention, presented by way of nonlimiting example, with reference to the accompanying drawings, wherein :
Figure 1 is a longitudinal sectional view of a railway vehicle equipped with a protection device according to the invention;
Figure 2 is a perspective view of the protection device of Figure 1 shown alone with the vehicle windshield.
Pour faciliter la lecture du dessin, seuls les éléments nécessaires à la compréhension de l'invention ont été représentés. Les mêmes éléments portent les mêmes références d'une figure à l'autre. To facilitate reading of the drawing, only the elements necessary for understanding the invention have been shown. The same elements have the same references from one figure to another.
La figure 1 représente un véhicule ferroviaire comportant une peau 6 réalisant l'enveloppe esthétique du véhicule et comportant un châssis inférieur 4 assurant la rigidité du véhicule et dont l'extrémité avant est munie d'élément absorbeur d'énergie 9. FIG. 1 represents a railway vehicle comprising a skin 6 producing the aesthetic envelope of the vehicle and comprising a lower chassis 4 ensuring the rigidity of the vehicle and the front end of which is provided with an energy absorbing element 9.
<Desc/Clms Page number 3><Desc / Clms Page number 3>
Conformément à la figure 1, la face avant du véhicule ferroviaire comporte un parebrise feuilleté 2 fixé de manière affleurante sur la peau 6 du véhicule. Le châssis inférieur 4 supporte une cabine de conduite 1 disposée derrière la face avant du véhicule, cette cabine de conduite comportant un pupitre de commande 5 placé à proximité de la base du pare-brise 2 du véhicule et un fauteuil en regard du pupitre pour accueillir le conducteur. Un bouclier de protection 3 est interposé entre la face avant du véhicule formée par la peau 6 du véhicule et l'intérieur de la cabine de conduite 1, ce bouclier de protection 3 étant supporté par le châssis inférieur 4. In accordance with FIG. 1, the front face of the railway vehicle comprises a laminated windshield 2 fixed flush with the skin 6 of the vehicle. The lower chassis 4 supports a driving cabin 1 arranged behind the front face of the vehicle, this driving cabin comprising a control console 5 placed close to the base of the windshield 2 of the vehicle and a chair opposite the console to accommodate the driver. A protective shield 3 is interposed between the front face of the vehicle formed by the skin 6 of the vehicle and the interior of the driver's cabin 1, this protective shield 3 being supported by the lower chassis 4.
Conformément à la figure 2, le bouclier de protection 3 comporte une structure métallique supportant une paroi frontale rigide, indéformable, s'étendant sur toute la hauteur de la cabine de conduite 1 et présentant une ouverture 8 disposée en regard du pare-brise 2 du véhicule, cette ouverture 8 permettant la vision du conducteur et possédant une surface réduite par rapport à la surface du pare-brise 2. Le bouclier de protection 3 comporte également deux parois latérales dont l'une est munie d'une ouverture pour permettre l'accès au conducteur. In accordance with FIG. 2, the protective shield 3 comprises a metal structure supporting a rigid, non-deformable front wall, extending over the entire height of the driver's cab 1 and having an opening 8 disposed opposite the windshield 2 of the vehicle, this opening 8 allowing the driver's vision and having a reduced surface relative to the surface of the windshield 2. The protective shield 3 also has two side walls, one of which is provided with an opening to allow the driver access.
Un tel véhicule équipé d'un bouclier de protection 3 permet, lors d'un choc avec un obstacle provoquant la projection du pare-brise 2 en direction de la cabine 1, par exemple par rupture de la coque plastique assurant le maintien de ce dernier, d'empêcher l'intrusion du pare-brise 2 dans la cabine de conduite 1. En effet, dans un tel cas, les bords du pare-brise 2 viennent s'appuyer sur les bords de l'ouverture 8 de la paroi frontale du bouclier de protection 3 limitant ainsi l'intrusion du pare-brise 2 dans la cabine de conduite 1. Such a vehicle equipped with a protective shield 3 makes it possible, during an impact with an obstacle causing the projection of the windshield 2 in the direction of the cabin 1, for example by rupture of the plastic shell ensuring the maintenance of the latter , to prevent the windshield 2 from intruding into the driver's cabin 1. Indeed, in such a case, the edges of the windshield 2 come to bear on the edges of the opening 8 of the front wall of the protective shield 3 thus limiting the intrusion of the windshield 2 into the driver's cabin 1.
De manière préférentielle, la largeur et la hauteur de l'ouverture 8 seront inférieures aux cotes du pare-brise 2 d'une vingtaine de centimètres, la capacité du bouclier de protection 3 à empêcher l'intrusion du pare-brise 2 dans la cabine de conduite 1 étant d'autant plus importante que l'ouverture 8 est de taille réduite par rapport à la taille du pare-brise 2. Preferably, the width and height of the opening 8 will be less than the dimensions of the windshield 2 by about twenty centimeters, the capacity of the protective shield 3 to prevent the intrusion of the windshield 2 into the cabin of pipe 1 being all the more important that the opening 8 is of reduced size compared to the size of the windshield 2.
Il résulte de ce qui précède que les risques d'intrusions du pare-brise ou d'autres objets dans la cabine sont minimisés et que la sécurité du conducteur est It follows from the above that the risks of intrusion of the windshield or other objects in the cabin are minimized and that the driver's safety is

indépendante de la résistance du dispositif de fixation du pare-brise sur la peau du véhicule. independent of the resistance of the windshield fixing device on the skin of the vehicle.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
Ainsi, dans une variante de réalisation non représentée le bouclier de protection pourra être réalisé par un treillis métallique.Thus, in a variant embodiment not shown, the protective shield could be produced by a wire mesh.
