Abstract: A vision system for mounting an imaging assembly to a helmet through a helmet adapter and a mounting assembly. The mounting assembly includes a receiver for removably mounting an imaging assembly. The receiver is coupled to a cross-slide assembly providing fore-aft and side-to-side movement of the imaging assembly relative to the helmet. A stow pivot/slide assembly is coupled between the cross-slide assembly and the helmet adapter for moving the imaging assembly between a stowed and a deployed position. The vertical position and tilt angle of the imaging assembly is also adjustable by the stow pivot/slide assembly.
