Title
(EN) AERODYNAMIC DEFLECTOR DEVICE SITUATED AT THE FRONT OF A MOTOR VEHICLE
(FR) DISPOSITIF DÉFLECTEUR AÉRODYNAMIQUE SITUÉ À L'AVANT D'UN VÉHICULE AUTOMOBILE
Abstract
(EN) Motor vehicle (V) having an aerodynamic deflector device comprising two deflector members mounted unitarily in front of a front wheel (R) of the vehicle, a said member comprising an air-guiding element (1) in the form of an L in which the smaller bar (10) of the L forms the rear part of said element, the large bar (11) of the L being in a position oriented in the longitudinal direction of the vehicle and the small bar (10) of the L being in a position oriented substantially in the vertical direction of the vehicle and directed downwardly when said element occupies an upper position, and said member comprising pivoting means (2) such that said element is able to pass reversibly as a function of speeds with a pivoting movement of approximately 90 degrees from its upper position to a lower position in which the large bar of the L is substantially vertical in front of the wheel.
(FR) Véhicule automobile (V) comportant un dispositif déflecteur aérodynamique comprenant deux organes déflecteurs se montant unitairement devant une roue avant du véhicule (R), undit organe comprenant un élément de guidage d'air (1) en forme de L dont la plus petite barre du L (10) forme la partie arrière dudit élément, la grande barre du L (11) étant dans une position orientée suivant la direction longitudinale du véhicule et la petite barre du L (10) étant dans une position orientée sensiblement suivant la direction verticale du véhicule et dirigée vers le bas quand ledit élément occupe une position haute, et ledit organe comprenant des moyens de pivotement (2) de sorte que ledit élément soit apte à passer réversiblement en fonction de vitesses suivant un pivotement d'environ 90 degrés de sa position haute vers une position basse dans laquelle la grande barre du L est sensiblement verticale devant la roue.
