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.
Claims29
A safety helmet, comprising:
- a helmet shell having a face cutout;
- a visor which is hingeably supported on both sides of the cutout on means defining a hinge axis and can be translated radially of the hinge axis outwardly from the shell from a tightly closed position to a tilting position, tilted circumferentially about the hinge axis, and locked by a control means at least in a first position in front of the cutout and a second position above the cutout, one of the visor and the shell having a fixed pivot pin and the control means being fixed to the other of the visor and the shell;
- and
- the control means acting radially relative to the hinge axis and having a control element received in a detent defining the tightly closed position, the control means having an elongated slot receiving the pivot pin and controlling tilting movement of the visor, whereby the visor can be sealed, vented and positioned at least at two extreme positions.
