Abstract
A helmet-mounted night vision system that is compact, light in weight and ejection-safe. The system incorporates a night vision goggles apparatus for receiving incoming infrared and/or visible light from a viewed object and for converting the incoming light to an intensified visible light for presentation to an eye of a user, a visor mounted to a helmet to be worn by the user and adapted to be positioned in front of the night vision goggles apparatus, and connecting structure for connecting the visor to the night vision goggles apparatus for retaining the visor in position in front of the night vision goggles apparatus. By ensuring that the visor is safely retained in front of and substantially fully covers the goggles apparatus at all times, the system of the invention is rendered ejection-safe. The system also provides the user with numerous other structural and operational advantages.
