Abstract (en)
[origin: WO2016097505A1] Cut-off mechanism for an automotive vehicle headlamp comprising a strip (5) borne by a movable assembly (40) and shaped to block to a greater or lesser extent a light beam so as to change the optical operating mode of said headlamp, said mechanism furthermore comprising a motor (6) for actuating said movable assembly using an electromagnet including an inductive coil (61) associated with a fixed ferromagnetic core (62) positioned in its centre and with a metal carcass (64) surrounding said coil, said movable assembly being movable under the action of said electromagnet, against the action of a return spring, between a contact position and a distant position, via a first air-gap (h1) of said ferromagnetic core (62). Said movable assembly (40) is shaped to create a rupture in the continuity of the magnetic circuit formed by said ferromagnetic core (62), said metal carcass (64) and said movable assembly (40), when it makes contact with said ferromagnetic core (62).
