ABSTRACT:
The vision limiting device, commonly known as a hood 40 comprises a unitary frame structure 41 having an inverted U-shape when in its operative position. The frame structure 41 includes a top wall 43 joining two spaced side walls 42 and 44, wherein when worn on the head of an aviator, the side walls 42 and 44 provide side shields for preventing peripheral view. In addition, the frame structure 41 includes a concave inner edge 45 that is shaped and configured to conform to the unique curvature of the central front outer portion of the Army sound protective helmet (SPH-4), as shown in FIG. 4. A front outer wall 46 connects the top wall 43 and side walls 44, wherein the front outer wall 46 includes a lip 48 which defines a generally inverted U-shaped cutaway opening 49. A bracket 50 supports a quick coupling means 52, which comprises a cylinder 54 having a spring loaded ball 55 on each end thereof. The quick coupling means 52 is compatible with the current quick coupling means located on the mounting structure currently used to mount an ANVIS goggle assembly. The hood 40 is easily attachable and detachable from the mounting structure of the helmet without the requirement of adapting a separate mounting structure for mounting the hood only.
