Abstract

An improved helmet mounting device for an optical or other viewing device is provided. The helmet mount includes a mounting assembly removably attachable to the helmet and a pivoting assembly having a first end pivotally attached to the mounting assembly and a second end opposite the first end. A fore and aft adjustment assembly is attached to the second end of the pivoting assembly and a left and right adjustment assembly is rotatably attached to the fore and aft adjustment assembly. The left and right adjustment assembly is pivotal relative to the fore and aft adjustment assembly about a first generally vertical axis. An optical device mounting member is attached to the left and right adjustment assembly and the optical device mounting member is removably attachable to the optical device. The mounting assembly includes a vertical adjust mechanism which has a base plate, a pair of guide rails attached to the base plate and defining a channel therebetween, a sliding plate slidably attached to the guide rails, and a clamping mechanism for selectively applying a clamping force to secure the sliding plate at a desired position relative to said base plate. In further aspects, modular electrical connectors and a remote battery box for providing power to the optical device or other viewing device are provided.
