Headlight for a motor vehicle with a cut-off beam, and a shield assembly for such a headlight

摘要

The object of the invention is a headlight for a motor vehicle comprising a reflector of the ellipsoidal type; a light source placed at a first focus of the reflector; a convergent optical means whose object focus is situated close to the second focus of the reflector; a first shield situated close to the second focus of the reflector and oriented transversely to the optical axis of the headlight with a substantially horizontal top edge; and a second shield substantially parallel to the first shield but offset along the optical axis in order to be situated closer to the optical means. The second shield is fixed to the first in order to form a single-piece assembly with a transverse section substantially in a V or U shape, the two arms of which correspond to the two shields.
