Abstract A mounting device and head support structure for carrying optical equipment, such as night vision goggles, on the head of a person, and including a structure which permits ready mounting and dismounting of the mounting device and the optical equipment carried thereby and also easy adjustment of the optical equipment in a vertical direction as well as along the line of vision after mounting. The mounting device includes a lever mounted in a housing and engagable by the user's hand when the mounting device and the optical equipment are grasped for mounting, and the lever is movable to a position to unlock engaging parts so as to permit the mounting device to move relative to the head support assembly and/or permit the part of the mounting device to which the optical equipment is attached to move relative to the housing. The two directions of movement are at 90° relative to each other, i.e., one is in the vertical direction and the other is in the horizontal direction, so as to be able to adjust the height of the optical equipment relative to the line of vision and to adjust along the line of vision. Additionally, it is possible to provide between the part of the mounting device which carries the optical equipment and the housing a pivot axis and adjustment member for engagement as well by the mounting hand of the wearer to accomplish a desired tilt of the optical equipment relative to the normal line of vision. The parts which provide the sliding connection between the housing of the mounting device and the head support assembly may be formed to permit complete separation when the lever is moved to an unlocking position so that the single lever can be activated to accomplish both mounting, dismounting and adjustment in the two directions indicated above. The head support assembly is designed to be worn continuously whenever it may be desirable to mount the optical equipment and permanently carries one of the separable parts in position exposed in front of the wearer's forehead. The head support assembly includes a main head piece which has a relatively rigid portion in the front and more flexible side and top pieces for fitting to a variety of head shapes. Webbing members connect the head piece to a chin piece and are of adjustable nature to provide strong securement to the wearer's head while permitting adjustment.
