Description

VEHICULE AUTOMOBILE COMPRENANT UN ORGANE DE PROTECTION DE LA TETE DU PILOTE  MOTOR VEHICLE COMPRISING A PILOT HEAD PROTECTION DEVICE
DOMAINE TECH NIQUE GENERAL ET ART ANTERIEUR La présente invention concerne le domaine de la course automobile et vise plus particulièrement un véhicule automobile comprenant un poste de pilotage ouvert et un organe de protection de la tête du pilote du véhicule. TECHNICAL FIELD AND PRIOR ART The present invention relates to the field of motor racing and more particularly to a motor vehicle comprising an open cockpit and a protection member of the driver's head of the vehicle.
De manière connue, un véhicule automobile pour la course automobile, tel qu'une voiture de formule 1 ou d'Indycar, comprend un châssis en carbone dans lequel est situé le poste de pilotage. As is known, a motor vehicle for motor racing, such as a Formula 1 or Indycar car, comprises a carbon chassis in which the cockpit is located.
En référence à la figure 1 , un pilote P du véhicule 1 accède au poste de pilotage 2 par une ouverture supérieure 3 du châssis 4 et la tête du pilote P dépasse du châssis 4 par cette ouverture 3 lorsqu'il conduit le véhicule 1 . Un tel poste de pilotage 2 est dit « ouvert ». La tête du pilote P est alors exposée aux chocs en cas d'accident, ce qui peut entraîner des blessures graves. Referring to Figure 1, a driver P of the vehicle 1 accesses the cockpit 2 through an upper opening 3 of the frame 4 and the driver's head P protrudes from the chassis 4 through this opening 3 when driving the vehicle 1. Such a cockpit 2 is called "open". The driver's head P is then exposed to impact in the event of an accident, which can lead to serious injuries.
Aussi, pour protéger la tête du pilote P, le châssis 4 comprend, de manière connue, un dispositif de protection arrière 5, connu de l'homme du métier sous le nom de « arceau arrière », s'élevant plus haut que la tête du pilote P afin de protéger le pilote P en cas de retournement du véhicule 1 et permettre son extraction du poste de pilotage 2. Cependant, un tel dispositif de protection arrière 5 ne permet pas de protéger la tête du pilote P des projectiles venant de l'avant, tel que, par exemple, un pneu ou une pièce de carrosserie qui se seraient détachés d'un véhicule concurrent et viendraient heurter la tête du pilote par l'avant. Also, to protect the head of the driver P, the chassis 4 comprises, in known manner, a rear protection device 5, known to those skilled in the art under the name of "rear bow", rising higher than the head pilot P to protect the driver P in the event of overturning of the vehicle 1 and allow its extraction from the cockpit 2. However, such a rear protection device 5 does not protect the head of the pilot P projectiles coming from the front, such as, for example, a tire or a body part that would have detached from a competing vehicle and would hit the pilot's head from the front.
Dans l'art antérieur, il a été proposé d'installer une bulle transparente au-dessus de l'ouverture du châssis afin de protéger le pilote. Cependant, une telle solution présente de nombreux inconvénients. Tout d'abord, une bulle ne possède pas les caractéristiques mécaniques suffisantes pour résister aux chocs les plus importants. De plus, la bulle gênerait le pilote en cas de retournement du véhicule en ralentissant son extraction. La bulle poserait également un problème quant au nettoyage de projections, notamment d'huile et de gomme, sur la bulle durant une course automobile, ce qui pourrait gêner la visibilité du pilote. La bulle est également contraire à la philosophie de ces courses automobiles dans lesquels le public a l'habitude de voir la tête du pilote. II a également été proposé un dispositif de protection en forme de V placé devant le pilote afin de dévier un objet venant de l'avant du véhicule. Cependant, un tel dispositif étant dans le champ de vision du pilote, la visibilité de ce dernier, notamment vers l'avant, est réduite, ce qui présente un inconvénient majeur. L'invention a donc pour but de remédier à au moins certains de ces inconvénients en proposant une protection de la tête du pilote qui soit efficace et qui ne gêne ni la visibilité, ni l'extraction du pilote. In the prior art, it has been proposed to install a transparent bubble above the opening of the frame to protect the pilot. However, such a solution has many disadvantages. First of all, a bubble does not have sufficient mechanical characteristics to withstand the most important shocks. In addition, the bubble would hinder the driver in case of overturning the vehicle by slowing down its extraction. The bubble would also pose a problem in the cleaning of projections, especially oil and gum, on the bubble during a race automobile, which could hinder the visibility of the driver. The bubble is also contrary to the philosophy of these car races in which the public is used to seeing the driver's head. It has also been proposed a V-shaped protective device placed in front of the driver to deflect an object coming from the front of the vehicle. However, since such a device is in the pilot's field of vision, the visibility of the latter, especially towards the front, is reduced, which presents a major drawback. The object of the invention is therefore to remedy at least some of these disadvantages by proposing a protection of the pilot's head which is effective and which does not hinder the visibility or the extraction of the pilot.
PRESENTATION GENERALE DE L'INVENTION GENERAL PRESENTATION OF THE INVENTION
A cet effet, l'invention concerne un véhicule automobile, en particulier pour la course automobile, comportant un châssis structural s'étendant longitudinalement d'arrière en avant et un poste de pilotage ouvert monté dans le châssis structural, le châssis structural comportant une ouverture permettant à un pilote dudit véhicule d'accéder audit poste de pilotage ouvert, l'ouverture comportant une partie avant apte à recevoir un volant et une partie arrière apte à recevoir la tête dudit pilote, le véhicule comprenant en outre au moins un organe de protection, positionné au-dessus du poste de pilotage et configuré pour protéger la tête du pilote, l'organe de protection étant monté audit châssis structural selon une pluralité de points d'ancrage à la périphérie de l'ouverture, un point d'ancrage gauche étant situé latéralement à gauche de l'ouverture, un point d'ancrage droit étant situé latéralement à droite de l'ouverture, l'organe de protection comportant au moins une portion, reliant le point d'ancrage gauche au point d'ancrage droit, qui s'étend en avant des points d'ancrage gauche et droit, la portion s'étendant en avant du point d'ancrage le plus en avant. For this purpose, the invention relates to a motor vehicle, in particular for motor racing, comprising a structural frame extending longitudinally from rear to front and an open cockpit mounted in the structural frame, the structural frame having an opening allowing a pilot of said vehicle to access said open cockpit, the opening having a front portion adapted to receive a steering wheel and a rear portion adapted to receive the head of said pilot, the vehicle further comprising at least one protective member , positioned above the cockpit and configured to protect the pilot's head, the protection member being mounted to said structural frame at a plurality of anchor points at the periphery of the opening, a left anchor point being located laterally to the left of the opening, a right anchor point being located laterally to the right of the opening, the protective member comprises at least one portion, connecting the left anchor point to the right anchor point, which extends forwardly from the left and right anchor points, the portion extending forward of the most before.
Grâce au véhicule selon l'invention, la tête du pilote du véhicule est protégée grâce à l'organe de protection s'étendant au-dessus de l'ouverture du poste de pilotage. De plus, la portion s'étendant en avant du point d'ancrage le plus en avant permet de protéger la tête du pilote sans gêner la visibilité du pilote. En effet, le point d'ancrage demeure en retrait du champ de vision tandis que la portion s'étend en avant pour intercepter tout projectile venant de l'avant et protéger le pilote. Enfin, une telle protection reliée au châssis peut résister à des efforts mécaniques importants lors d'un choc, ce qui permet d'assurer la protection du pilote de manière optimale. Thanks to the vehicle according to the invention, the driver's head of the vehicle is protected by the protective member extending above the opening of the cockpit. In addition, the portion extending forward of the foremost anchor point allows protect the pilot's head without hindering the visibility of the pilot. Indeed, the anchor remains behind the field of vision while the portion extends forward to intercept any projectile coming from the front and protect the pilot. Finally, such a protection connected to the chassis can withstand significant mechanical forces during a shock, which ensures the protection of the driver optimally.
De préférence, l'organe de protection s'étend en avant des points d'ancrage gauche et droit sur une distance supérieure à 18 cm, de préférence supérieure à 25 cm. Ainsi, l'organe de protection est situé au-dessus du champ de vision du pilote afin de ne pas gêner sa visibilité. Preferably, the protective member extends forwardly left and right anchor points over a distance greater than 18 cm, preferably greater than 25 cm. Thus, the protection member is located above the pilot's field of vision so as not to hinder his visibility.
De manière préférée, l'organe de protection est monté mobile par rapport au châssis afin de permettre un accès rapide au poste de pilotage tout en protégeant le pilote. De préférence, l'organe de protection est mobile en rotation par rapport au châssis selon un axe de rotation au niveau d'au moins un des points d'ancrage gauche ou droit. Ainsi, l'organe de protection peut aisément pivoter par rotation, basculant entre une position ouverte et une position fermée. Selon une première forme de réalisation de l'invention, l'axe de rotation est orienté pour permettre une rotation de l'organe de protection sur le côté du véhicule en position ouverte. Preferably, the protection member is mounted movably relative to the frame to allow quick access to the cockpit while protecting the pilot. Preferably, the protective member is rotatable relative to the frame along an axis of rotation at at least one of the left or right anchor points. Thus, the protection member can easily rotate by rotation, tilting between an open position and a closed position. According to a first embodiment of the invention, the axis of rotation is oriented to allow rotation of the protective member on the side of the vehicle in the open position.
Selon une deuxième forme de réalisation de l'invention, l'axe de rotation est orienté sensiblement transversalement de manière à permettre une rotation de l'organe de protection en arrière en position ouverte. According to a second embodiment of the invention, the axis of rotation is oriented substantially transversely so as to allow rotation of the protective member back in the open position.

Ainsi, le sommet de l'organe de protection est situé au- dessus du champ de vision. De manière préférée, l'organe de protection présente une forme arquée vers l'avant afin de dévier sur les côtés un objet venant de l'avant et afin d'augmenter la résistance mécanique de l'organe de protection lors d'un choc.

DESCRIPTION D'UN OU PLUSIEURS MODES DE REALISATION ET DE MISE EN OEUVRE DESCRIPTION OF ONE OR MORE MODES OF REALIZATION AND IMPLEMENTATION
En référence aux figures 2 à 5, il est représenté de manière schématique une forme de réalisation d'un véhicule automobile 10 selon l'invention. Dans cet exemple, il est représenté un véhicule de course monoplace du type formule 1 . Il va de soi que l'invention s'applique aux véhicules biplaces ainsi qu'à tout véhicule dont le poste de pilotage est ouvert, notamment, du type Indycar, Formula E, Superformula, etc. En référence à la figure 2 et de manière connue, le véhicule automobile 10 comprend un châssis 20 s'étendant longitudinalement selon un axe X, orienté de l'arrière vers l'avant, auquel sont fixées des roues 1 1 . Dans cet exemple, le véhicule 10 comporte en outre un nez avant 12 et un aileron arrière 13. Le châssis 20 est la structure rigide sur laquelle sont montés les différents éléments du véhicule 10 tel que les organes de transmission, de motorisation, etc. Un tel châssis 20 est adapté pour supporter des efforts mécaniques importants et permet en outre de protéger le pilote P comme cela sera présenté par la suite. Dans le domaine de la course automobile, un tel châssis 20 est, de préférence, un châssis-coque. Autrement dit, le châssis 20 est intégré à la carrosserie du véhicule 10. Un tel châssis 20 peut être moulé ou tubulaire et, par exemple, réalisé en fibres de carbone ou en aluminium afin d'assurer une bonne rigidité du châssis 20 et de minimiser son poids. En référence aux figures 3 et 4, le châssis 20 comprend en outre une ouverture 21 permettant au pilote P d'accéder à un poste de pilotage 30. Le poste de pilotage 30 comprend un siège (non représenté) sur lequel le pilote P est assis durant une course automobile, et un volant 31 permettant de piloter le véhicule 10. Le poste de pilotage 30 est ouvert, autrement dit, lorsque le pilote P est installé dans le poste de pilotage 30, sa tête dépasse dudit poste de pilotage 30. De manière connue, le volant 31 est amovible afin de faciliter l'accès du pilote P au poste de pilotage 30. De même, le siège peut être extrait du poste de pilotage 30 avec le pilote P après un choc afin de maintenir le dos du pilote P. Le poste de pilotage 30 est situé dans le châssis 20 afin de protéger le pilote P comme cela sera présenté par la suite. En référence à la figure 3, l'ouverture 21 d'accès au poste de pilotage 30 s'étend longitudinalement d'avant en arrière et comprend une partie avant 21 A, apte à recevoir le volant 31 , et une partie arrière 21 B apte à recevoir la tête du pilote P. With reference to FIGS. 2 to 5, there is shown schematically an embodiment of a motor vehicle 10 according to the invention. In this example, there is shown a single-seat race vehicle of the formula 1 type. It goes without saying that the invention applies to two-seater vehicles and any vehicle whose cockpit is open, including the type Indycar, Formula E, Superformula, etc. Referring to Figure 2 and in known manner, the motor vehicle 10 comprises a frame 20 extending longitudinally along an axis X, oriented from the rear to the front, which are fixed wheels 1 January. In this example, the vehicle 10 further comprises a front nose 12 and a rear wing 13. The frame 20 is the rigid structure on which are mounted the various elements of the vehicle 10 such as the transmission members, engine, and so on. Such a frame 20 is adapted to withstand significant mechanical forces and further protects the driver P as will be presented later. In the field of automobile racing, such a chassis 20 is preferably a chassis-shell. Other said frame 20 is integrated with the body of the vehicle 10. Such a frame 20 may be molded or tubular and, for example, made of carbon fiber or aluminum to ensure a good rigidity of the frame 20 and to minimize its weight. With reference to FIGS. 3 and 4, the frame 20 further comprises an opening 21 allowing the pilot P to access a cockpit 30. The cockpit 30 comprises a seat (not shown) on which the pilot P sits during a car race, and a steering wheel 31 for controlling the vehicle 10. The cockpit 30 is open, in other words, when the pilot P is installed in the cockpit 30, his head protrudes from said cockpit 30. known manner, the steering wheel 31 is removable to facilitate access of the pilot P to the cockpit 30. Similarly, the seat can be removed from the cockpit 30 with the driver P after a shock to maintain the back of the pilot P. The cockpit 30 is located in the chassis 20 to protect the pilot P as will be presented later. With reference to FIG. 3, the access opening 21 to the cockpit 30 extends longitudinally from front to back and comprises a front portion 21 A, capable of receiving the steering wheel 31, and a rear portion 21 B adapted to receive the head of the pilot P.
Dans cet exemple, en référence aux figures 2 à 5, afin d'assurer la sécurité du pilote P, le châssis 20 comprend, d'une part, un dispositif de protection arrière 22 pour protéger le pilote P en cas de retournement du véhicule 10 et faciliter son extraction et, d'autre part, deux dispositifs de protection latérale basse 23 du pilote P afin de protéger, durant une course automobile, le pilote P en cas de choc latéral bas, c'est-à-dire, au niveau de son poste de pilotage 30, sous la tête du pilote P. Le dispositif de protection arrière 22, connu de l'homme du métier sous le nom de « arceau arrière » ou « arceau central » ou encore « arceau de sécurité », s'étend verticalement vers le haut en arrière du poste de pilotage 30. De préférence, le dispositif de protection arrière 22 s'étend sur une hauteur comprise entre 26 cm et 48 cm au-dessus du poste de pilotage 30. Dans cet exemple, le dispositif de protection arrière 22 et les dispositifs de protection latérale basse 23 sont réalisés en fibres de carbone et issus de matière du châssis 20. De manière classique, un appui tête est monté de manière amovible au dispositif de protection latéral 23. Un tel appui tête présente une forme globale en U afin de maintenir en place la tête du pilote P à l'intérieur du poste de pilotage 30 durant une course. Comme illustré à la figure 2, le châssis 20 comprend de manière optionnelle une protection latérale haute 24 s'étendant verticalement en saillie du dispositif de protection latérale 23 afin de protéger la tête du pilote P des objets venant des côtés. In this example, with reference to FIGS. 2 to 5, in order to ensure the safety of the driver P, the chassis 20 comprises, on the one hand, a rear protection device 22 to protect the driver P in the event of the vehicle being turned over. and facilitate its extraction and, secondly, two low side protection devices 23 of the driver P to protect, during a car race, the driver P in case of side impact low, that is to say, at the level its cockpit 30, under the head of the pilot P. The rear protection device 22, known to those skilled in the art under the name of "rear bow" or "central arch" or "roll bar", s extends vertically upwards behind the cockpit 30. Preferably, the rear protection device 22 extends over a height of between 26 cm and 48 cm above the cockpit 30. In this example, the rear protection device 22 and latching devices 23 are made of carbon fibers and derived from material of the frame 20. In a conventional manner, a head support is removably mounted to the lateral protection device 23. Such a head support has a global U-shape to maintain places the pilot's head P inside the cockpit 30 during a race. As illustrated in FIG. 2, the frame 20 optionally comprises a high lateral protection 24 extending vertically protruding from the lateral protection device 23 in order to protect the driver's head P from the objects coming from the sides.
En référence aux figures 2 à 5, le véhicule 10 comprend en outre un organe de protection 40, positionné au-dessus du poste de pilotage 30. Un tel organe de protection 40 est configuré pour protéger la tête du pilote P sans perturber son champ de vision. Par « champ de vision » du pilote, on entend le champ de vision principal du pilote, autrement dit lorsqu'il regarde vers l'avant du véhicule. Ainsi, l'organe de protection 40 ne perturbe pas son champ de vision en lui laissant la vue sur la route. With reference to FIGS. 2 to 5, the vehicle 10 further comprises a protection member 40 positioned above the flight deck 30. Such a protection member 40 is configured to protect the pilot's head P without disturbing his field of view. vision. By "field of vision" of the pilot is meant the pilot's main field of vision, ie when looking towards the front of the vehicle. Thus, the protection member 40 does not disturb its field of vision by leaving the view on the road.
Selon une forme de réalisation préférée, l'organe de protection 40 est monté mobile par rapport au châssis structural 20 afin de basculer entre une position fermée de protection de la tête du pilote P comme illustré à la figure 2, par exemple durant une course automobile, et une position ouverte facilitant l'accès du pilote P au poste de pilote 30 comme illustré à la figure 3. Il a été présenté un organe de protection 40 mobile par rapport au châssis 20, mais il va de soi que l'organe de protection 40 pourrait être monté fixe sur le châssis 20. According to a preferred embodiment, the protective member 40 is mounted to move relative to the structural frame 20 to switch between a closed position of protection of the head of the driver P as shown in Figure 2, for example during a car race , and an open position facilitating the access of the pilot P to the pilot station 30 as shown in FIG. 3. A protective member 40 has been shown movable relative to the frame 20, but it goes without saying that the protection 40 could be fixedly mounted on the chassis 20.
Selon une première forme de réalisation, l'organe de protection 40 est monté solidairement audit châssis structural 20 selon une pluralité de points d'ancrage. Dans cet exemple, en référence à la figure 4, l'organe de protection 40 est fixé au châssis 20 en deux points d'ancrage PI , P2 : un point d'ancrage gauche PI situé latéralement à gauche de l'ouverture 21 , de préférence au niveau d'un dispositif de protection latéral 23, de préférence encore à l'avant du dispositif de protection latéral 23, et un point d'ancrage droit P2 situé latéralement à droite de l'ouverture 21 , de préférence au niveau d'un dispositif de protection latéral 23, de préférence encore à l'avant du dispositif de protection latéral 23. De préférence, les points d'ancrage gauche et droit PI , P2 sont situés symétriquement de chaque côté de l'ouverture 21 . According to a first embodiment, the protection member 40 is integrally mounted to said structural frame 20 according to a plurality of anchor points. In this example, with reference to FIG. 4, the protection member 40 is fixed to the frame 20 at two anchoring points PI, P2: a left anchor point PI located laterally to the left of the opening 21, preferably at the level of a lateral protection device 23, more preferably at the front of the lateral protection device 23, and a right anchor point P2 located laterally to the right of the opening 21, preferably at the level of a lateral protection device 23, preferably still in front of the lateral protection device 23. Preferably, the left and right anchor points PI, P2 are located symmetrically on each side of the opening 21.
Comme illustré à la figure 4, l'organe de protection 40 comporte une portion 41 , reliant le point d'ancrage gauche PI au point d'ancrage droit P2, qui s'étend latéralement en avant du pilote P afin de le protéger, c'est-à-dire sensiblement perpendiculairement à l'axe X du véhicule 10. La portion 41 présente une forme arquée vers l'avant et s'étendant en avant des points d'ancrage gauche et droit PI , P2. Autrement dit, la portion 41 s'étend, jusqu'à un sommet S, en avant des points d'ancrage gauche et droit P I , P2, de préférence à une distance longitudinale Ll supérieure à 18 cm, de préférence comprise entre 18 cm et 45 cm, de préférence de l'ordre de 30 cm comme illustré à la figure 6. L'organe de protection 40 pourrait également comprendre un sommet S pointu. As illustrated in FIG. 4, the protection member 40 comprises a portion 41 connecting the left anchor point PI to the right anchor point P2, which extends laterally in front of the pilot P in order to protect it, c that is to say substantially perpendicularly to the X axis of the vehicle 10. The portion 41 has an arcuate shape forward and extending forward left and right anchor points PI, P2. In other words, the portion 41 extends, up to a vertex S, in front of the left and right anchor points PI, P2, preferably at a longitudinal distance L1 greater than 18 cm, preferably between 18 cm and 45 cm, preferably of the order of 30 cm as shown in Figure 6. The protection member 40 could also include a pointed vertex S.
La portion 41 s'étend verticalement vers le haut depuis chacun des points d'ancrage gauche et droit PI , P2 jusqu'au sommet S sur une hauteur hl comprise entre 5 cm et 16 cm, de préférence de l'ordre de 8 cm. Vu de côté, l'organe de protection est incliné vers l'avant d'un angle a l compris entre 10° et 35° par rapport au plan horizontal. Ainsi, le sommet S, bien que situé en avant des points d'ancrage gauche et droit PI , P2, protège la tête du pilote P sans gêner son champ de vision du fait que le sommet S s'étend en hauteur des points d'ancrage PI , P2. En particulier, le sommet S s'étend au- dessus du champ de vision du pilote P. Ainsi, l'organe de protection 40 s'étend au- dessus de la tête du pilote P afin de le protéger. The portion 41 extends vertically upwards from each of the left and right anchor points PI, P2 to the top S on a height h1 between 5 cm and 16 cm, preferably of the order of 8 cm. Seen from the side, the protection member is inclined forwards at an angle to l between 10 ° and 35 ° relative to the horizontal plane. Thus, the top S, although located in front of the left and right anchor points PI, P2, protects the head of the pilot P without hindering his field of view because the vertex S extends in height of the points of PI anchoring, P2. In particular, the summit S extends above the field of view of the pilot P. Thus, the protection member 40 extends above the head of the pilot P to protect it.
L'organe de protection 40 comporte une première extrémité 41 A et une deuxième extrémité 41 B, chaque extrémité 41 A, 41 B reliant l'organe de protection 40 au châssis 20 au niveau d'un des points d'ancrage gauche PI ou droit P2. The protection member 40 has a first end 41 A and a second end 41 B, each end 41 A, 41 B connecting the protection member 40 to the frame 20 at one of the left or right anchor points PI P2.
Dans cette forme de réalisation, l'organe de protection 40 comprend respectivement, au niveau de ses extrémités 41 A, 41 B, une charnière 6 et un système de verrouillage 7 de l'organe de protection 40 en position fermée. Ainsi, l'organe de protection 40 peut être ouvert et fermé de manière pratique. In this embodiment, the protection member 40 comprises respectively, at its ends 41A, 41B, a hinge 6 and a locking system 7 of the protective member 40 in the closed position. Thus, the protection member 40 can be conveniently opened and closed.
Comme illustré à la figure 7, la charnière 6 est montée au niveau de la première extrémité 41 A de la portion 41 de l'organe de protection 40. Dans cet exemple, la charnière 6 comporte un corps longitudinal 42 s'étendant selon un axe de rotation XI . Le corps longitudinal 42 est adapté pour être monté mobile dans le châssis 20 afin de permettre la rotation de l'organe de protection 40 selon l'axe de rotation XI . Le corps longitudinal 42 comprend une surface cylindrique s'étendant selon l'axe de rotation XI afin de permettre la rotation par complémentarité de forme avec le châssis 20. Avantageusement, l'axe de rotation XI s'étend coaxialement à l'axe selon lequel s'étend la première extrémité 41 A de la portion 41 afin de permettre la rotation de l'organe de protection 40 sur le côté du véhicule 10. De préférence, l'axe de rotation XI est incliné par rapport au plan horizontal selon l'angle d'inclinaison al de l'organe de protection 41 . De préférence, le corps longitudinal 42 s'étend dans le prolongement de la portion 41 de l'organe de protection 40. De préférence encore, le corps longitudinal 42 est issu de matière de ladite portion 41 . As illustrated in FIG. 7, the hinge 6 is mounted at the first end 41A of the portion 41 of the protection member 40. In this example, the hinge 6 comprises a longitudinal body 42 extending along an axis of rotation XI. The longitudinal body 42 is adapted to be movably mounted in the frame 20 to allow the rotation of the protective member 40 along the axis of rotation XI. The longitudinal body 42 comprises a cylindrical surface extending along the axis of rotation XI in order to allow rotation by complementary form with the frame 20. Advantageously, the axis of rotation XI extends coaxially with the axis along which extends the first end 41 of the portion 41 to allow the rotation of the protective member 40 on the side of the vehicle 10. Preferably, the axis of rotation XI is inclined relative to the horizontal plane according to the inclination angle α1 of the protection member 41. Preferably, the longitudinal body 42 extends in the extension of the portion 41 of the protective member 40. More preferably, the longitudinal body 42 is made of material of said portion 41.
Il a été présenté un corps longitudinal 42, mais il va de soi que toute autre forme de charnière permettant la rotation de l'organe de protection 40 pourrait convenir. De même, tout système autre qu'une charnière et permettant la rotation de l'organe de protection 40, en particulier selon un axe, pourrait convenir. It has been shown a longitudinal body 42, but it goes without saying that any other form of hinge allowing the rotation of the protective member 40 could be suitable. Similarly, any system other than a hinge and allowing the rotation of the protective member 40, in particular along an axis, could be suitable.
Comme illustré à la figure 8, le système de verrouillage 7 est monté au niveau de la deuxième extrémité 41 B de la portion 41 de l'organe de protection 40. Dans cet exemple, le système de verrouillage 7 comprend une goupille 43 adaptée pour traverser, au moins partiellement, le châssis 20 et l'organe de protection 40 afin de les verrouiller ensemble et interdire toute rotation. Ainsi, la goupille 43 est insérée dans le châssis 20 et dans l'organe de protection 40 au niveau de sa deuxième extrémité 41 B pour bloquer la rotation de l'organe de protection 40 par rapport au châssis 20. Ainsi, l'organe de protection 40 est solidaire du châssis 20 en position fermée afin de protéger la tête du pilote P. Pour que le pilote P rentre ou sorte du poste de pilotage 30, la goupille 43 est retirée, permettant ainsi le basculement de l'organe de protection 40 jusqu'à sa position ouverte. Avantageusement, une telle goupille 43 est aisée à retirer afin de permettre une extraction rapide du pilote P du poste de pilotage 30. De plus, la goupille 43 peut être aisément retirée par le pilote P ou bien par une personne tierce située en dehors du véhicule 10, notamment par le personnel de secours. As illustrated in FIG. 8, the locking system 7 is mounted at the second end 41 B of the portion 41 of the protection member 40. In this example, the locking system 7 comprises a pin 43 adapted to traverse , at least partially, the frame 20 and the protection member 40 to lock them together and prohibit any rotation. Thus, the pin 43 is inserted in the frame 20 and in the protective member 40 at its second end 41 B to block the rotation of the protective member 40 relative to the frame 20. Thus, the member of protection 40 is secured to the frame 20 in the closed position to protect the head of the pilot P. For the pilot P to enter or exit the cockpit 30, the pin 43 is removed, thus allowing the tilting of the protection member 40 to its open position. Advantageously, such a pin 43 is easy to remove in order to allow rapid extraction of the pilot P from the cockpit 30. In addition, the pin 43 can be easily removed by the pilot P or by a third person located outside the vehicle 10, especially by the rescue staff.
Il a été présenté une goupille 43, cependant il va de soi que tout autre système permettant le blocage de l'organe de protection en position fermé pourrait convenir, en particulier, une broche. It has been shown a pin 43, however it goes without saying that any other system for locking the protective member in closed position could be suitable, in particular, a pin.
Il a été présenté une charnière 6 montée au niveau du point d'ancrage gauche PI et un système de verrouillage 7 au niveau du point d'ancrage droit P2, cependant il va de soi que la charnière 6 pourrait être montée au niveau du point d'ancrage droit P2 et que le système de verrouillage 7 pourrait être monté au niveau du point d'ancrage gauche PI . L'organe de protection 40 pivotant alors vers la droite. De préférence, l'organe de protection 40 se présente sous la forme d'une structure tubulaire ou profilée, dite en aile d'avion. Dans cet exemple, la portion 41 de l'organe de protection 40 est tubulaire et présente une section sensiblement circulaire. Il a été présenté un organe de protection 40 présentant une section circulaire cependant il va de soi que toute autre section, par exemple ovale ou rectangulaire, pourrait convenir. Une telle structure tubulaire est discrète et n'impacte pas visuellement l'esthétique du véhicule automobile. En particulier, le pilote P demeure visible depuis l'extérieur du véhicule 10 malgré la présence de l'organe de support 40. Selon un premier mode de réalisation, la structure tubulaire est pleine afin d'optimiser la résistance mécanique de l'organe de protection 40. Selon un deuxième mode de réalisation, la structure tubulaire est creuse afin de limiter la masse de l'organe de protection 40 tout en présentant une résistance mécanique élevée. It was presented a hinge 6 mounted at the left anchor point PI and a locking system 7 at the right anchor point P2, however it goes of course that the hinge 6 could be mounted at the right anchor point P2 and that the locking system 7 could be mounted at the left anchor point PI. The protection member 40 then pivots to the right. Preferably, the protection member 40 is in the form of a tubular or profiled structure, called an aircraft wing. In this example, the portion 41 of the protection member 40 is tubular and has a substantially circular section. It has been presented a protective member 40 having a circular section however it is obvious that any other section, for example oval or rectangular, could be suitable. Such a tubular structure is discrete and does not visually impact the aesthetics of the motor vehicle. In particular, the pilot P remains visible from outside the vehicle 10 despite the presence of the support member 40. According to a first embodiment, the tubular structure is solid in order to optimize the mechanical strength of the protection 40. According to a second embodiment, the tubular structure is hollow in order to limit the mass of the protection member 40 while having a high mechanical strength.
De préférence, l'organe de protection 40 est réalisé en un matériau léger présentant une résistance importante aux efforts mécaniques, par exemple de la fibre de carbone ou du titane. De manière avantageuse, tout effort mécanique reçu par l'organe de protection 40 est ainsi transmis au châssis 20, les efforts mécaniques étant alors absorbés de manière optimale par le véhicule 10. Preferably, the protection member 40 is made of a light material having a high resistance to mechanical forces, for example carbon fiber or titanium. Advantageously, any mechanical force received by the protection member 40 is thus transmitted to the frame 20, the mechanical forces then being absorbed optimally by the vehicle 10.
Il a été présenté un organe de protection 40 comprenant une unique portion 41 . Cependant, il va de soi que l'organe de protection 40 pourrait comprendre deux portions, chaque portion comprenant à une extrémité une charnière et à une autre extrémité un système de verrouillage. Chaque portion étant ainsi montée mobile par rapport au châssis au niveau de leur charnière et étant reliée ensemble par leur système de verrouillage. It has been presented a protection member 40 comprising a single portion 41. However, it goes without saying that the protection member 40 could comprise two portions, each portion comprising at one end a hinge and at another end a locking system. Each portion thus being mounted movable relative to the frame at their hinge and being connected together by their locking system.
Selon une deuxième forme de réalisation et en référence aux figures 9 et 10, l'organe de protection 40 comprend une charnière (non représentée) au niveau de chacune de ses extrémités 41 A, 41 B. L'axe de rotation des charnières s'étend transversalement, c'est-à-dire perpendiculairement à l'axe X du véhicule, afin de permettre à l'organe de protection 40 de pivoter vers le haut. Avantageusement, les axes de rotation des charnières sont coaxiaux afin de faciliter la rotation de l'organe de protection 40. Une telle charnière peut par exemple comprendre un corps longitudinal, tel que décrit précédemment, s'étendant transversalement. According to a second embodiment and with reference to FIGS. 9 and 10, the protection member 40 comprises a hinge (not shown) at each of its ends 41 A, 41 B. The axis of rotation of the hinges extends transversely, that is to say perpendicularly to the axis X of the vehicle, to allow the protection member 40 to pivot upwards. Advantageously, the axes of rotation of the hinges are coaxial to facilitate the rotation of the protective member 40. Such a hinge may for example comprise a longitudinal body, as described above, extending transversely.
Comme illustré à la figure 1 1 , la portion 41 de l'organe de protection 40 présente, vue de côté, une première partie avant s'étendant sensiblement horizontalement depuis le sommet S et une deuxième partie arrière s'étendant obliquement vers le bas jusqu'à un des points d'ancrage gauche ou droit PI , P2. Le véhicule automobile 10 comprend deux renforts 50 s'étendant sensiblement verticalement depuis chacun des dispositifs de protection latérale 23. En position fermée, l'organe de protection 40 est en appui, au niveau de sa partie avant, sur les renforts 50.

'at one of the left or right anchor points PI, P2. The motor vehicle 10 comprises two reinforcements 50 extending substantially vertically from each of the lateral protection devices 23. In the closed position, the protection member 40 is supported, at its front portion, on the reinforcements 50.
Il a été présenté des renforts 50 s'étendant depuis le châssis 20, cependant il va de soi que ces renforts 50 pourraient être solidaires de l'organe de protection 40 et s'étendre verticalement sous la partie avant de l'organe de protection 40 de manière à être en appui sur le châssis 20 en position fermée de l'organe de protection 40. It has been shown reinforcements 50 extending from the frame 20, however it goes without saying that these reinforcements 50 could be integral with the protective member 40 and extend vertically under the front portion of the protective member 40 so as to bear on the frame 20 in the closed position of the protection member 40.
De préférence, l'organe de protection 40 comprend un système de verrouillage de l'organe de protection 40 en position fermée. Un tel système de verrouillage permet de relier de manière solidaire l'organe de protection 40 et le châssis 20 et d'interdire toute ouverture. De préférence, le système de verrouillage est adapté pour coopérer avec au moins un des renforts 50 afin de verrouiller la position de l'organe de protection 40 par rapport au châssis 20. Le système de verrouillage pourrait comprendre une goupille telle que décrite précédemment. Preferably, the protection member 40 comprises a locking system of the protection member 40 in the closed position. Such a locking system makes it possible to connect the protection member 40 and the frame 20 together and to prevent any opening. Preferably, the locking system is adapted to cooperate with at least one of the reinforcements 50 to lock the position of the protective member 40 relative to the frame 20. The locking system could comprise a pin as described above.
Pour permettre l'accès au poste de pilotage 30, le système de verrouillage est tout d'abord déverrouillé puis l'organe de protection 40 pivote vers le haut, laissant libre accès à l'ouverture 23 d'accès au poste de pilotage 30. To allow access to the cockpit 30, the locking system is first unlocked and then the protection member 40 pivots upwards, leaving free access to the access opening 23 to the cockpit 30.
