ABSTRACT:
A curved visor mechanism for helmets with laterally moveable visors that move on guides that define a track attached to the helmet. The visors are curved in the shape of a sector of an annulus of a circle. Using such a shape allows the track defined by the visors to maintain a nonzero rake angle at the front of the face area of the helmet, while preventing retracted visors from extending too close to the bottom of the back of the helmet. Removal of the visors from the helmet is accomplished by removing sections of the guides in which the visors move, preferably at the front of the helmet. This creates notches in the guides through which a visor can easily be inserted into and out of the helmet.
