Abstract:

A headgear (10) for supporting a night vision goggle (12) to the head of a wearer. A flexible temporal strip (18) is joined to a flexible crown strip (20) in the forehead region, at which juncture a pair of integral rails (74, 76) suspend the goggle (12) therefrom. The temporal strip (18) and crown strip (20) include free ends which are directed toward the posterior of the cranium (22) and are connected by straps (36, 46, 48) to a webbed pad (38) which engages the occipital protuberance to prevent forward rotation of the headgear (10) due to the weight of the goggle (12). Lower girth straps (68, 69) maintain attachment of the headgear (10) to the cranium (22) and further aid in antirotational movement.

Appl. No.:

Inventors:

Richard T. Hart - Garland TX

Assignee:

Varo, Inc. - Garland TX

International Classification:

A42B 124
A61F 902

US Classification:

22091

Abstract:

An adjustment mechanism for adjusting headgear-mounted vision equipment with respect to the viewer's eyes. A goggle (14) is mounted to a carriage (20) which is slideable on a frame (10) mounted to the headgear (12). The carriage (20) is slideable on a rail (16) by a tongue and groove arrangement (48), and slideable on a rod (42). The carriage (20) includes a cavity (62) with a coil spring (64) therein encircling the rod (42). In its relaxed state, the coil spring (64) firmly engages the rod (42) and prevents movement of the carriage (20) on the rod (42). The coil spring ends (66, 68) are compressible together to release the engagement of the coil spring (64) about the rod (42). A finger-operated plunger assembly (28) includes a slotted end (118) for engaging one spring end (68). When the plunger button (116) is depressed, the spring ends (66, 68) are pressed together, thereby permitting adjustment of the carriage (20) on the rod (42).
