Abstract

La présente invention concerne un projecteur (10) pour véhicule automobile, comprenant une source lumineuse (16), un réflecteur (14) du type elliptique dont un premier foyer est situé au voisinage de la source (16), une lentille convergente (18) dont un plan focal passe au voisinage d'un second foyer du réflecteur (14), un premier (24) et un deuxième (26) caches qui sont intercalés axialement, suivant l'axe optique (A-A) du projecteur (10), entre le réflecteur (14) et la lentille (18), du type dans lequel le premier cache (24) est monté pivotant autour d'un axe (B-B) sensiblement transversal entre deux positions extrêmes.The present invention relates to a projector (10) for a motor vehicle, comprising a light source (16), a reflector (14) of the elliptical type of which a first focus is located in the vicinity of the source (16), a converging lens (18) a focal plane passes in the vicinity of a second focus of the reflector (14), a first (24) and a second (26) covers which are interposed axially, along the optical axis (AA) of the projector (10), between the reflector (14) and the lens (18), of the type in which the first cover (24) is pivotally mounted about a substantially transverse axis (BB) between two extreme positions.

Selon la présente invention, le second cache (26) est monté à pivotement autour du même axe de pivotement (B-B), le second cache (26) étant monté libre à rotation autour de l'axe de pivotement (B-B) et n'étant soumis qu'à l'action d'un ressort (60, 72) et d'un élément de verrouillage (64, 66 ; 80).

Figure imgaf001
According to the present invention, the second cover (26) is pivotally mounted about the same pivot axis (BB), the second cover (26) being rotatably mounted about the pivot axis (BB) and not subject to the action of a spring (60, 72) and a locking member (64, 66; 80).
