ABSTRACT:
A fire fighter helmet of the type having a body which includes a peripheral brim, an arcuate face shield having an inwardly extending lip and a flexible gasket on the underside of the lip for forming a watertight seal with the brim when the shield is in a down position, and a pair of hinges attached to opposite sides of the helmet body and pivotably attached to the face shield. The hinges each include a hinge plate and a spring which is connected at one end to the shield and at an opposite to the hinge plate rearwardly and below the pivot connection between the hinge plate and face shield. The hinge plate also includes a stop defining an upper limit of travel for the face shield. The spring urges the shield to pivot either to an up position against the stop, or to a down position in which the gasket forms a watertight seal with the adjacent portion of the helmet body brim.
