ABSTRACT:
The disclosed pair of hinges enables the visor to be swung with respect to the shell of the helmet in a complex motion that starts in a turned-down position by a motion of translation moving the visor away from the shell of the helmet in order to move it away from a shoulder or joint, if any, and continues up to a raised position by a rotation that retracts the visor over the shell of the helmet. They are synchronized mechanically by a system of gear wheels meshing with racks connected by a sheathed cable and being operated by just one hand by one of the handles with which it is fitted.
