Abstract

A dual visor and helmet assembly in which inner and outer visors mounted on arbors secured to opposite sides of the helmet for movement between operative and inoperative positions are clamped respectively to one and to the other of the arbors by pre-loaded C-rings coupled to the visors.
Respective manually actuatable operating rings on the visors may be actuated to release the clamping forces of the C-rings and to move the visors between their operative and inoperative positions.
