A headlamp adjuster (10, 10a, 10b) configured for engagement with a reflector (16) of a headlamp assembly (12). The headlamp adjuster includes a U-shaped structure (24, 24a, 24b) which is engaged with a screw (22, 22a) and which is engageable with the reflector. The screw is prevented from translating substantially upon rotation, but the headlamp adjuster is configured such that rotation of the screw causes the U-shaped structure to translate thereby moving the reflector. The screw includes an externally threaded shaft portion (28) which is threadably engaged with an internally threaded bore (46) of the U-shaped structure. The U-shaped structure may be a single piece which is engaged with the screw and is engageable with the reflector, or may include a U-shaped member (36b) which is engaged with the screw and a slide member (76), where the slide member is engageable with the reflector.

L'invention concerne un ajusteur (10, 10a, 10b) pour lampe frontale conçu pour recevoir un réflecteur (16) d'ensemble lampe frontale (12). Ledit ajusteur de lampe frontale possède une structure en U (24, 24a, 24b) dans laquelle s'engage une vis (22, 22a) et s'engageant dans le réflecteur. La vis ne peut décrire de mouvement de translation sensible lorsqu'elle est mue en rotation, mais l'ajusteur de lampe frontale est configuré de manière que la rotation de la vis induise la translation de la structure en U et ainsi le déplacement du réflecteur. La vis comprend une partie tige à filetage extérieur(28), qui se vis dans un alésage à filetage intérieur (46) de la structure en U. La structure en U peut se composer d'une seule pièce dans laquelle s'engage la vis et qui s'emboîte avec le réflecteur, ou peut comprendre un élément en U (36b) dans lequel s'engage la vis et un élément coulissant (76), lequel (76) s'engage dans le réflecteur.
