ABSTRACT:
An assembly for mounting a shield on a safety helmet of the type having a helmet body in the front opening, includes two male locking members, each secured to a respective left and right outer surface of the helmet body, and two female locking members, each secured to a respective left and right shield side. Each male locking member includes a recess having an inlet portion at the periphery thereof and an engaging shoulder. Each female locking member includes a boss and a guide piece at the periphery thereof for insertion in a respective recess and inlet portion only when the shield is moved to a disengagement position above the normal upper limit position. The guide piece of each female locking member is engaged by the engaging shoulder of the respective male locking member when the shield is moved out of the disengagement position, with the recess and boss rotatably supporting the shield for rotational movement on the helmet body. A moderating device for guiding the shield during rotation thereof includes a resilient engaging piece mounted on each male locking member and an arcuate guide groove is formed in the respective female locking member for receiving the resilient engaging piece and guiding the same during rotation of the shield. A stopper is mounted on the male locking member for engaging the lower peripheral edge of the shield during normal operation thereof, so as to define the upper limit of rotation of the shield at such time.
