Abstract

A helmet system having a visor attached to a support bracket mounted on a helmet wherein the support bracket is formed with an extension operative to block the visor from lifting upwards when the visor is pushed toward the helmet by wind pressure while not obstructing the normal circumferential movement of said visor in the absence of wind pressure.

Claims

1. A helmet system having a visor attached to a support bracket mounted on a helmet wherein the support bracket is formed with an extension operative to block the visor from lifting upwards when the visor is pushed toward the helmet by wind pressure while not obstructing the normal circumferential movement of said visor in the absence of wind pressure.

2. A helmet system according to claim 1 and comprising a display image source attached to the support bracket which projects images onto the visor, wherein the position of the projected images is adjustably changed by changing the mounting position of the bracket on the helmet.

3. A helmet system according to claim 2 wherein an adjustment in the mounting position results in a vertical movement of the image on the visor.

4. A helmet system according to claim 3 wherein an adjustment in the mounting position results in a horizontal movement of the image on the visor.

5. A helmet system according to claim 2 wherein an adjustment in the mounting position results in a horizontal movement of the image on the visor.

6. A helmet system according to claim 1 wherein said visor is constructed out of a relatively shape retaining material.

7. A helmet system according to claim 6 wherein the relatively shape retaining material is polycarbonate plastic.

8. A helmet system according to claim 1 and comprising visor fasteners.

9. A helmet system comprising

a helmet;

a visor attached to said helmet; and

a ridge formed on said helmet operative to prevent said visor from lifting upwards when the visor is pushed toward the helmet by wind pressure while not obstructing the normal circumferential movement of said visor in absence of said wind pressure.

10. A helmet system according to claim 9 and comprising a display image source attached to a bracket which projects images onto the visor, wherein the position of the projected images is adjustably changed by changing the mounting position of the source on the helmet.

11. A helmet system according to claim 10 wherein an adjustment in the mounting position results in a vertical movement of the image on the visor.

12. A helmet system according to claim 10 wherein an adjustment in the mounting position results in a horizontal movement of the image on the visor.

13. A helmet system according to claim 10 wherein an adjustment in the mounting position results in a horizontal movement of the image on the visor.

14. A helmet system according to claim 9 wherein said visor is constructed out of a relatively shape retaining material.

15. A helmet system according to claim 14 wherein the relatively shape retaining material is polycarbonate plastic.

16. A helmet system according to claim 9 and comprising visor fasteners.
