Abstract
Apparatus for detachably securing a night vision goggle mount to a protective helmet visor housing in which the heads of a pair of upper fasteners carried by the mount are adapted to be inserted through the head receiving portions of a pair of upper keyhole slots in a base plate on the housing against the action of a leaf spring on the plate. When the shanks of the fasteners are moved into the lower head-retaining portions of the upper slots, the upper fastener heads are held by ears on the leaf spring to lock the mount. A releasing element on the base plate is adapted to be actuated to flex the spring to a position at which the spring ears are clear of the upper fastener heads to permit the mount to be removed. Preferably, a pair of lower fasteners having heads and a pair of corresponding lower keyhole slots are provided to insure stability and alignment of the night vision goggle mount.
