ABSTRACT:
A dual-visor assembly for use with a helmet such as that of an aircraft crew member in which an inner visor is releasably secured to the helmet by snap fasteners that release toward the rear of the helmet, while an outer visor is releasably secured to the helmet over the inner visor by snap fasteners that release toward the front of the helmet to prevent the inadvertent release of both visors simultaneously. The snap fasteners are carried by straps that are secured to the inner surface of the inner visor and to the outer surface of the outer visor to prevent entanglement. Elements carried by the visors space the inner visor from the outer visor as well as from the surface of the helmet. A soft cover is releasably secured over the outer visor in its raised position to prevent scratching of the outer visor or other structures.
