ABSTRACT:
The disclosure concerns a device for adjusting the aiming direction of a motor vehicle headlight reflector, said device comprising three essentially localized bearing points to support said reflector against a relatively fixed structure, the three bearing points being placed at the three apexes of a triangle having one horizontal side, one of said points being fixed and the other two points being adjustable through shifting in a direction that is essentially perpendicular to the plane of said triangle, to cause heightwise and lateral variation in the aiming direction of the reflector, and further comprising driving means capable of moving at least one of the two adjustable points, wherein the two adjustable bearing points are located on one and the same lateral side of the headlight, opposite the fixed support, the driving means include a single driving member, and means are provided for selectively connecting the driving member to a first adjustable bearing point, which is horizontally aligned with the fixed bearing point, or fixing in position said adjustable bearing point, while said driving member is permanently connected to the second adjustable bearing point so as to determine the two modes of adjustment.
