Abstract: A universal dual visor assembly for helmets in which inner and outer lenses are supported by a pair of hollow shafts rotatably carried by the helmet and provided with bores of noncircular cross section which slidably receive pushbuttons of corresponding noncircular cross section for axial movement between a shaft locking position at which locking elements thereon selectively engage in spaced recesses in the shaft housing to hold the corresponding shaft in a selected position and a release position at which the shaft is free to rotate. One lens is coupled to one of the shafts for rotation therewith while being free to rotate with respect to the other shaft while the other lens is coupled to the other shaft for rotation therewith while being free to rotate with respect to the one shaft.
