A protective helmet, including a shell (2) defining a face opening (4) and having left and right side portions (8), a slide (15) arranged on each of the side portions of the shell, wherein the slides are symmetrical relative to a longitudinal plane of symmetry (P) of the shell, a face-shield (3) having a central portion (11) and mounted on the shell and configured to move between a lowered position in which the face-shield extends opposite the face opening and a raised position in which the face opening is substantially bared, and two side wings (12) on the face-shield, each having at least one upper connecting member (16) and at least one lower connecting member (17). The connecting members are configured to engage in a corresponding slide of the shell to guide the movement of the face- shield between the lowered position and the raised position. Methods for placing a face-shield in position on a shell of a protective helmet are also provided. |
