Abstract

Attachment systems for attaching accessories to a helmet shell and their methods of use are described. In one embodiment, an attachment system may include a first attachment portion mounted to a helmet shell and extending through an opening in an associated accessory. The attachment system also may include a second attachment portion that is selectively connectable to the first attachment portion. A surface of the second attachment portion facing the helmet shell engages with a bearing surface of the accessory to selectively attach the accessory to the helmet shell. In certain embodiments, the first and second attachment portions may be selectively connected to one another using a connector that moves the second attachment portion both vertically and horizontally relative to the first attachment portion when the connector is tightened.

First claim

What is claimed is:

1. An attachment system comprising:
a first attachment portion that is mountable to a helmet shell, wherein the first attachment portion includes a protrusion that extends through an opening through an accessory; and
a second attachment portion that is selectively connectable to the protrusion of the first attachment portion extending through the opening of the accessory, wherein a surface of the second attachment portion that faces the helmet shell is engagable with a bearing surface of the accessory to selectively attach the accessory to the helmet shell when the second attachment portion is connected to the first attachment portion with the accessory disposed between the first attachment portion and the second attachment portion, and wherein the second attachment portion is moveable along an axis that is angled at a non-orthogonal angle relative to a surface of the underlying helmet shell when the first attachment portion is mounted thereto, and wherein the second attachment portion is moveable along the axis in a direction toward the protrusion of the first attachment portion.

2. The attachment system of claim 1 , further comprising a connector that selectively connects the second attachment portion to the first attachment portion.

3. The attachment system of claim 2 , wherein tightening the connector moves the second attachment portion both horizontally and vertically relative to the first attachment portion.

4. The attachment system of claim 1 , further comprising the accessory.

5. The attachment system of claim 1 , wherein the accessory comprises a front mount.

6. The attachment system of claim 1 , further comprising the helmet shell.

7. The attachment system of claim 1 , further comprising a lock constructed and arranged to maintain a position of the accessory relative to the helmet shell.

8. The attachment system of claim 7 , further comprising the accessory, and wherein the lock comprises a protrusion that complements a size and shape of the opening of the accessory.

9. The attachment system of claim 4 , where the accessory comprises a carrier that is attachable to a front of the helmet shell, the carrier including first and second arms which extend in opposite directions away from a central region of the carrier.

10. An attachment system comprising:
a first attachment portion that is mountable to a helmet shell;
a second attachment portion;
a connector that selectively connects the second attachment portion to the first attachment portion, wherein when the connector is tightened, the second attachment portion moves both vertically and horizontally relative to the first attachment portion and a surface of the underlying helmet shell when the first attachment portion is mounted thereto, and wherein the vertical and horizontal movement of the second attachment portion compresses a bearing surface of an accessory between a first surface of the first attachment portion and a second surface of the second attachment portion located opposite the first surface when the bearing surface is compressed therebetween to selectively attach the accessory to the helmet shell.

11. The attachment system of claim 10 , further comprising the accessory.

12. The attachment system of claim 11 , wherein the accessory comprises a front mount.

13. The attachment system of claim 10 , wherein the accessory comprises a carrier configured to be attached to a front of the helmet shell, the carrier including first and second arms which extend in opposite directions away from a central region of the carrier.

14. The attachment system of claim 10 , further comprising the helmet shell.

15. The attachment system of claim 10 , further comprising a lock constructed and arranged to maintain a position of the accessory relative to the helmet shell.

16. The attachment system of claim 15 , further comprising the accessory, and wherein the lock comprises a protrusion that complements a size and shape of an opening of the accessory.

17. The attachment system of claim 1 , wherein the axis is angled at an angle between or equal to 5° and 30° relative to the surface of the underlying helmet shell when the first attachment portion is mounted thereto.

18. The attachment system of claim 1 , wherein the surface of the second attachment portion that engages the bearing surface of the accessory maintains its orientation relative to the helmet shell while the second attachment portion is moved along the axis angled at a non-orthogonal angle relative to the helmet shell.

19. The attachment system of claim 18 , wherein the surface of the second attachment portion that engages the bearing surface of the accessory is oriented parallel relative to the surface of the underlying helmet shell.

20. The attachment system of claim 10 , wherein the second attachment portion includes a surface that faces the helmet shell and is engageable with a bearing surface of the accessory to selectively attach the accessory to the helmet shell when the second attachment portion is connected to the first attachment portion, and wherein the surface of the second attachment portion that engages the bearing surface of the accessory maintains its orientation relative to the helmet shell while the second attachment portion is moved along an axis angled at a non-orthogonal angle relative to the helmet shell.

21. The attachment system of claim 20 , wherein the surface of the second attachment portion that engages the bearing surface of the accessory is oriented parallel relative to the surface of the underlying helmet shell.

22. The attachment system of claim 1 , wherein the accessory is compressed between the first attachment portion and the second attachment portion.

23. The attachment system of claim 1 , wherein the second attachment portion is displaceable towards the first attachment portion to engage the bearing surface of the accessory.

24. An attachment system comprising:
a first attachment portion that is mountable to a helmet shell, wherein the first attachment portion includes a protrusion that extends outward away from a surface of the underlying helmet shell;
a second attachment portion;
a threaded connector that extends between and selectively connects the second attachment portion to the protrusion of the first attachment portion, wherein the threaded connector is threaded into the protrusion of the first attachment portion and is oriented along an axis that is angled at a non-orthogonal angle relative to an underlying surface of the helmet shell, and wherein adjusting the threaded connector adjusts a spacing between the first and second attachment portions, and wherein an orientation of a surface of the second attachment portion facing the underlying surface of the helmet shell is maintained when the threaded connector is adjusted.

25. The attachment system of claim 24 , wherein the surface of the second attachment portion facing the underlying surface of the helmet shell is parallel to the underlying surface of the helmet shell.

26. The attachment system of claim 24 , wherein the axis of the threaded fastener is parallel to the underlying surface of the underlying helmet shell and the surface of the second attachment portion is not parallel to the underlying surface of the helmet shell.

27. The attachment system of claim 1 , wherein a normal force applied to the bearing surface by the second attachment portion is oriented
