Abstract

The bonnet (1) has a movable skirt (2) mounted on a transversal axis (3), and a jack (4) that is arranged such that the skirt is lifted among a predetermined speed. The axis extends perpendicular to a longitudinal axis of a motor vehicle and the jack is coupled to a triggering device which measures the speed of the vehicle. The skirt has a shape optimized according to general geometry of the vehicle.

Description

Domaine techniqueTechnical area

Capot moteur d'un véhicule automobile intégrant un saute vent.  Motor hood of a motor vehicle incorporating a wind jump.

Etat de la technique On sait que les capots des véhicules automobiles intègrent, tant que possible, des aspects aérodynamiques dans leur conception.  STATE OF THE ART It is known that the hoods of motor vehicles include, as far as possible, aerodynamic aspects in their design.

Problème posé par cet état de la technique Mais on sait également que le style du véhicule prime presque toujours sur les considérations techniques et que la présence d'organes considérés comme inesthétiques est prohibée, même si de tels organes procurent de réels avantages techniques.  Problem posed by this state of the art But we also know that the style of the vehicle is almost always preceded by technical considerations and that the presence of organs considered unsightly is prohibited, even if such organs provide real technical advantages.

C'est ainsi que la présence d'un saute vent (ou déflecteur) sur le capot d'un véhicule automobile n'est jamais constatée, sinon sous une forme très embryonnaire, alors qu'un tel organe serait souhaitable pour dévier les lignes de courant vers le haut et éviter des phénomènes tourbillonnaires dus à la dépression qui se crée à la base du pare- brise.  Thus, the presence of a wind deflector (or deflector) on the hood of a motor vehicle is never observed, except in a very embryonic form, whereas such a body would be desirable to deflect the lines of current upwards and avoid swirling phenomena due to the depression that is created at the base of the windshield.

Solution proposée par l'invention L'invention a pour objet un capot de véhicule automobile, caractérisé en ce qu'il comporte un panneau pivotant monté sur un axe essentiellement transversal et un actionneur agencé de manière que ledit panneau mobile se lève à partir d'une vitesse prédéterminée.  The invention relates to a hood of a motor vehicle, characterized in that it comprises a pivoting panel mounted on a substantially transverse axis and an actuator arranged so that said movable panel rises from a predetermined speed.

La position levée du panneau pivotant est définie de préférence comme position permettant de réduire la cassure de pente entre le capot et le pare-brise, de manière que le panneau remplisse ainsi une fonction de becquet ou de spoiler.  The raised position of the pivoting panel is preferably defined as a position to reduce the slope break between the hood and the windshield, so that the panel thus fulfills a spoiler or spoiler function.

Un avantage de l'invention, au-delà des considérations esthétiques, est que le panneau pivotant peut être relativement imposant sans pour cela gêner la visibilité pour le conducteur lors des manoeuvres de stationnement et pour la circulation en ville, car dans ces deux cas la vitesse du véhicule est insuffisante pour déclencher la montée du panneau pivotant.  An advantage of the invention, beyond the aesthetic considerations, is that the pivoting panel can be relatively large without affecting the visibility for the driver during parking maneuvers and city traffic, because in both cases the speed of the vehicle is insufficient to trigger the rise of the pivoting panel.

Modes de réalisation particuliers avantageux - Le capot est réalisé en matière plastique.  Particular advantageous embodiments - The cover is made of plastic.

- Le panneau mobile est réalisé en matière plastique.  - The mobile panel is made of plastic.

Description d'un exempleDescription of an example

Afin de mieux faire comprendre l'invention, on va en décrire un mode de réalisation donné à titre d'exemple non limitatif de la portée de l'invention, à l'aide de la figure unique annexée qui est une vue en perspective d'un capot.  In order to better understand the invention, an embodiment given by way of non-limiting example of the scope of the invention will be described with the aid of the single appended figure which is a perspective view of a cap.

Référence Explication 2 Le bandeau mobile est une pièce en matière plastique.  Reference Explanation 2 The mobile headband is a plastic part.

Sa forme doit être optimisée en fonction de la géométrie générale du véhicule.  Its shape must be optimized according to the general geometry of the vehicle.

3 L'axe, dit essentiellement transversal, est sensiblement vertical une fois le capot monté sur le véhicule, et s'étend perpendiculairement à l'axe longitudinal du véhicule.  3 The axis, said essentially transverse, is substantially vertical once the hood mounted on the vehicle, and extends perpendicularly to the longitudinal axis of the vehicle.

4 L'actionneur est couplé à un dispositif (non représenté) déclencheur qui mesure (ou récupère d'une centrale informatique embarquée) la vitesse de déplacement du véhicule. -3.-  The actuator is coupled to a trigger device (not shown) which measures (or retrieves from an on-board computer unit) the speed of movement of the vehicle. -3.-
