Abstract

A protective helmet includes: a rigid shell including a generally domed-shaped section, a three attenuating liner within the dome-shaped section shell and operatively connected to the rigid shell; and a visor mount in operative connection with the force attenuating liner, the visor mount be adapted to have a visor mounted thereto.

Claims (17)

1. A protective helmet comprising:

a rigid shell including a generally domed-shaped section,

a force attenuating liner within the dome-shaped section of the rigid shell and operatively connected to the rigid shell; and

a visor mount in operative connection with the force attenuating liner, the visor mount being adapted to have a visor mounted thereto; and

a chin strap attached to the force attenuating liner;

a visor pivotably mounted to the visor mount so that the visor is pivotable to a stowed state between the force attenuating liner and the rigid shell,

wherein the force attenuating liner is adapted to disconnect from operative connection with the rigid shell under a predetermined load, the visor mount being adapted to remain in connection with the force attenuating liner upon disconnection of the force attenuating liner from operative connection with the rigid shell.

2. The protective helmet of claim 1 wherein the visor mount includes a section that extends at least partially around an outer surface of the force attenuating liner.

3. The protective helmet of claim 2 wherein the section of the visor mount extends over a top of the force attenuating liner.

4. The protective helmet of claim 3 wherein the rigid shell includes a rib extending side to side over a top of the dome-shaped section, at least a portion of the visor mount being located within an interior portion of the rib.

5. The protective helmet of claim 3 wherein the dome-shaped section of the rigid shell includes a rib extending front to back, at least a portion of the visor mount being located within the top center portion of the rib.

6. The protective helmet of claim 3 wherein the dome-shaped section of the rigid shell is generally rounded over the dome-shaped section, at least a portion of the visor mount being located adjacent to an interior surface of the dome shaped section.

7. The protective helmet of claim 2 wherein the section of the visor mount extends around a side of the force attenuating liner.

8. The protective helmet of claim 2 wherein the section of the visor mount extends around a perimeter of the force attenuating liner.

9. The protective helmet of claim 1 wherein the visor mount and the force attenuating liner are operatively connected to the rigid shell via a connector which disconnects from operative connection with the rigid shell under a predetermined load.

10. The protective helmet of claim 1 wherein the visor mount is operatively connected to the rigid shell via a connector which disconnects from operative connection with the rigid shell under a predetermined load.

11. The protective helmet of claim 10 wherein the force attenuating liner is connected to the visor mount so that upon disconnection of the visor mount from the rigid shell, the force attenuating liner disconnects from operative connection with the rigid shell and remains connected to the visor mount.
