A flip-up helmet mount for a night vision device is disclosed. The flip-up helmet mount includes a position adjustment assembly for adjusting the position of the night vision device between a use and a stowed position, a tilt adjustment assembly for adjusting the tilt angle of the night vision device relative to a user's eyes, and a focal adjustment assembly for adjusting the focus or location of the night vision device relative to the user's eyes. The assemblies provided for position, tilt, and focus adjustment all permit one-handed adjustment of these features of the flip-up helmet mount. Additionally, the flip-up helmet mount includes an improved automatic shutdown assembly that provides reliable shutdown of the night vision device when not in the use position.
