Abstract: A pair of rail adapters which replace visor rails used on the U.S. Army Ahe helmets, i.e. the AH-64 helmet. The rail adapters have a concave inner portion that is form fitted and attachable to the Apache helmet, with one rail adapter on each of the right and left upper front sides of the Apache helmet. The rail adapters have a convex outer portion that interface and is attachable with a visor guard Aviator's Night Vision Imaging System (ANVIS) goggle assembly and visor which are normally used with the U.S. Army ANVIS helmet, i.e. the SPH-4 helmet. Each of the rail adapters is made in one piece which has a thick upper portion with a half dovetailed open track in which the outer portion of the visor guard is attachable thereto. The rail adapters have a thin lower portion which provides clearance with the visor and the ANVIS goggle assembly when the visor and the assembly are in the line of sight position.

Abstract: A face protecting visor is provided for use when wearing optical devices h a helmet. A clear viewing portion of the visor is retained in the helmet by a bezel portion which extends structurally to bear against the outer surface of the helmet, thereby translating impact forces thereagainst to the helmet rather than the face. Included on the visor is one mating part of a catch mechanism located on the bezel portion for detachably affixing the optical devices thereto. Elastic members with snaps are also connected to the bezel portion for removably securing it to the helmet. A catch-stop mechanism on the interior of the bezel portion translates the gravitational loads of the visor to the helmet.
