Abstract

In one aspect, a shroud assembly for headgear includes a frame formed of a polymer material having a shape that matches a contour of the headgear. An insert is formed of metal or metal alloy and is attached to a front side of the frame. The insert is configured for removable attachment to a mounting assembly. The frame includes first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert. The first and second flexible walls are spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls. In another embodiment, the shroud assembly further includes a friction pad disposed on a rear surface of the frame for increasing friction between the shroud assembly and the headgear. In another aspect, a method for attaching a mounting assembly to headgear is provided.

Claims

1. A shroud assembly for headgear, comprising:

a frame having a shape that matches a contour of the headgear;

an insert attached to a front side of the frame, the insert configured for removable attachment to a mounting assembly;

the frame including first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert, said first and second flexible walls spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls;

a friction pad disposed on a rear surface of the frame for increasing friction between the shroud assembly and the headgear; and

a first opening in the insert, a second opening in the frame, and a third opening in the friction pad, wherein the first, second, and third openings are aligned with an opening in the headgear for receiving a mechanical fastener attaching the shroud assembly to the headgear.

2. The shroud assembly of claim 1, wherein the first and second walls extend vertically on opposite lateral sides of the insert.

3. The shroud assembly of claim 1, wherein the first and second walls are configured to be displaced outward when the mounting assembly is removably attached to the insert.

4. The shroud assembly of claim 1, wherein each of the first and second walls have a tapered inward facing surface to facilitate insertion of the mounting system.

5. The shroud assembly of claim 1, further comprising:

said insert defining one or more receptacles configured to removably mate with a latch member of the mounting assembly.

6. The shroud assembly of claim 1, wherein the insert is formed of a metal or metal alloy.

7. The shroud assembly of claim 1, wherein the frame is formed of a material selected from the group consisting of an injection moldable thermoplastic resin, a fiber reinforced polymer matrix composite material, and a glass fiber reinforced polyimide matrix composite material.

8. The shroud assembly of claim 1, further comprising:

at least one opening in the frame configured to receive a mechanical fastener for attaching the shroud assembly to the headgear.

9. The shroud assembly of claim 8, wherein said at least one opening comprises a plurality of openings positioned in accordance with a promulgated standard for headgear drill hole patterns.

10. The shroud assembly of claim 9, wherein the promulgated standard is the MARSOC/WARCOM three-hole pattern.

11. The shroud assembly of claim 1, wherein the position of the first opening corresponds to a military standard headgear single drill hole pattern.

12. The shroud assembly of claim 1, further comprising:

at least one boss protruding from the friction pad and extending through a complementary opening in the frame.

13. The shroud assembly of claim 1, further comprising:

fourth, fifth, and sixth openings in the frame;

seventh, eight, and ninth openings in the friction pad, the seventh, eight, and ninth openings aligned with the fourth, fifth, and sixth openings, respectively; and

a removable plug received in each of the seventh, eight, and ninth openings.

14. The shroud assembly of claim 1, further comprising the mounting assembly.

15. The shroud assembly of claim 14, wherein the mounting assembly is a night vision device mounting assembly.

16. The shroud assembly of claim 1, wherein the frame is formed of a polymer material.

17. A shroud assembly for headgear, comprising:

a frame having a shape that matches a contour of the headgear;

an insert attached to a front side of the frame, the insert configured for removable attachment to a mounting assembly;

the frame including first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert, said first and second flexible walls spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls;

a friction pad disposed on a rear surface of the frame for increasing friction between the shroud assembly and the headgear; and

at least one boss protruding from the friction pad and extending through a complementary opening in the frame.

18. The shroud assembly of claim 17, wherein the first and second walls extend vertically on opposite lateral sides of the insert.

19. The shroud assembly of claim 17, wherein the first and second walls are configured to be displaced outward when the mounting assembly is removably attached to the insert.

20. The shroud assembly of claim 17, wherein each of the first and second walls have a tapered inward facing surface to facilitate insertion of the mounting system.

21. The shroud assembly of claim 17, further comprising:

said insert defining one or more receptacles configured to removably mate with a latch member of the mounting assembly.

22. The shroud assembly of claim 17, wherein the insert is formed of a metal or metal alloy.

23. The shroud assembly of claim 17, wherein the frame is formed of a material selected from the group consisting of an injection moldable thermoplastic resin, a fiber reinforced polymer matrix composite material, and a glass fiber reinforced polyimide matrix composite material.

24. The shroud assembly of claim 17, further comprising:

at least one opening in the frame configured to receive a mechanical fastener for attaching the shroud assembly to the headgear.

25. The shroud assembly of claim 24, wherein said at least one opening comprises a plurality of openings positioned in accordance with a promulgated standard for headgear drill hole patterns.

26. The shroud assembly of claim 25, wherein the promulgated standard is the MARSOC/WARCOM three-hole pattern.

27. The shroud assembly of claim 17, wherein the position of the first opening corresponds to a military standard headgear single drill hole pattern.

28. The shroud assembly of claim 17, further comprising the mounting assembly.

29. The shroud assembly of claim 28, wherein the mounting assembly is a night vision device mounting assembly.

30. The shroud assembly of claim 17, wherein the frame is formed of a polymer material.

31. A shroud assembly for headgear, comprising:

a frame having a shape that matches a contour of the headgear;

an insert attached to a front side of the frame, the insert configured for removable attachment to a mounting assembly;

the frame including first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert, said first and second flexible walls spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls;
