ABSTRACT:
A safety helmet has a shell with a visor movably supported on both sides. By means of a bearing pin and a control pin guided along cam surfaces, the visor can be positioned over the face opening of the helmet or swung upwardly. Detents for the pins define positions for the visor including a flush mounting in the face opening, a venting position at which the visor is spaced from the helmet shell but remains over the face opening, and an upward position. These positions are preferably achieved by means of a control disc having displacement and rotation defining detents, engaging the bearing and control pins on each side of the visor.
