  • Patent number: 6472776
    Abstract: A flip-up helmet mount for a night vision device with a goggle horn for attachment to the helmet mount is disclosed. The flip-up helmet mount includes an adjustable socket assembly for mounting goggle horns with varying dimensions therein, and an improved automatic shutdown assembly that provides for reliable shutdown of the night vision device when not operational. Additionally, 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.

  • Patent number: 6457179
    Abstract: A helmet mount for a night vision device with a goggle horn for attachment to the helmet mount is disclosed. The helmet mount includes an adjustable socket assembly for mounting goggle horns with varying dimensions therein, and a break away latch assembly in the lower socket that allows a goggle horn to be removed if a certain predetermined force is applied to the night vision device. Additionally, the helmet mount includes a vertical adjustment system for changing the vertical position of the night vision device relative to the user's eyes. The vertical movement can be achieved by either a rack/pin system or a gear drive system. Also provided is a locking mechanism that allows the night vision device to be easily changed from the stowed or in use position by compressing an activation button that disengages the locking mechanism and allows the night vision to be flipped up or down.
