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 engageable 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 single lever can be activated to accomplish both mounting, dismounting and adjustment in the two directions indicated above.
