Abstract
A helmet mount includes a helmet block, a chassis attached to the helmet block, the chassis adapted to receive the night vision device, and a vertical adjustment assembly for vertically adjusting a night vision device relative to a user'"'"'s eyes while the helmet mount is secured to the helmet and the night vision device is received in the helmet mount. The vertical adjustment assembly includes a front and back plate that are slidably connected, wherein the front plate is coupled to the chassis and the back plate is coupled to the helmet mount, and a gear drive system. Rotating a lever on the gear drive system rotates the gear so that the vertical position of the chassis is changed relative to the helmet block. The gear driven system further includes at least one biasing means placed between the front plate and the back plate and may include a tapered shaft.
