Abstract

A protective helmet having multiple protective zones, including an inner shell having a first inner surface and a first outer surface, an outer shell having a second inner surface, a second outer surface, and at least one window defined by said outer shell, said outer shell functionally attached to said inner shell, an elastomeric zone between said first outer surface and said second inner surface, a plurality of sinusoidal springs positioned in said elastomeric zone, each of the plurality of sinusoidal springs including a first end, and a second end, a force indicator tab in operative contact with said second end of at least one of said plurality of sinusoidal springs, wherein said force indicator tab is displaced in said at least one window by said second end when said helmet is impacted with sufficient force, and a transmission device.

First claim

What is claimed is:

1. A protective helmet having multiple protective zones, comprising:
an inner shell having a first inner surface and a first outer surface;
an outer shell having a second inner surface, a second outer surface, and at least one window defined by said outer shell, said outer shell functionally attached to said inner shell;
an elastomeric zone between said first outer surface and said second inner surface;
a plurality of sinusoidal springs positioned in said elastomeric zone, each of the plurality of sinusoidal springs comprising:
a first end; and,
a second end;

a force indicator tab in operative contact with said second end of at least one of said plurality of sinusoidal springs, wherein said force indicator tab is displaced in said at least one window by said second end when said helmet is impacted with sufficient force; and, a transmission device.

2. The protective helmet as recited in claim 1 , further comprising a plurality of piston devices arranged between the inner and outer shells, wherein each of said plurality of piston devices comprises:
a first component connected to the second end; and,
a second component.

3. The protective helmet as recited in claim 2 , wherein the second component comprises:
a dashpot;
an arm including a plurality of notches, the arm slidingly engaged with the dashpot; and,
a barrier including a plurality of doors.

4. The protective helmet as recited in claim 3 , wherein the first component is a cylinder and is operatively arranged to:
move axially along the barrier;
pass through the plurality of doors; and,
engage the plurality of notches.

5. The protective helmet as recited in claim 1 , wherein said first end of at least one of said plurality of sinusoidal springs is attached to said first outer surface.

6. The protective helmet as recited in claim 1 , wherein each one of said plurality of sinusoidal springs is attached at a common point on said inner shell.

7. The protective helmet as recited in claim 1 , further comprising a plurality of brackets connected to said first outer surface, said second inner surface, or both said first outer surface and said second inner surface, wherein said plurality of brackets are operatively arranged adjacent to said plurality of sinusoidal springs to limit with a lateral and torsional movement of said plurality of sinusoidal springs.

8. The protective helmet as recited in claim 1 , wherein said at least one window extends in a generally sagittal direction.

9. The protective helmet as recited in claim 1 , wherein said force indicator tab is positioned in a slot or between two rails.

10. The protective helmet as recited in claim 9 , wherein said force indicator tab comprises a return tab.

11. The protective helmet as recited in claim 1 , wherein the transmission device comprises:
a power source;
a sensor arranged to determine a location of the force indicator tab in the window; and,
a transmitter arranged to transmit a signal indicating the location to a remote receiver.

12. The protective helmet as recited in claim 1 , wherein the transmission device comprises:
a power source;
a sensor arranged to determine an extent that the force indicator tab is displaced; and,
a transmitter arranged to transmit a signal indicating the extent to a remote receiver.

13. The protective helmet as recited in claim 1 , further comprising a plurality of locking devices arranged between the inner and outer shells, wherein each of said plurality of locking devices includes:
a first portion comprising a first plurality of teeth, the first portion connected to the second end;
a second portion comprising a second plurality of teeth, the second portion arranged on the first outer surface, wherein the first plurality of teeth are arranged to engage the second plurality of teeth; and,
a release device connected to the first portion, the release device is operatively arranged to release said locking device.

14. A protective helmet having multiple protective zones, comprising:
an inner shell having a first inner surface and a first outer surface;
an outer shell having a second inner surface and a second outer surface, said outer shell functionally attached to said inner shell;
an elastomeric zone between said first outer surface and said second inner surface;
a plurality of sinusoidal springs positioned in said elastomeric zone, each of the plurality of sinusoidal springs comprising:
a first end; and,
a second end; and,
a transmission device, including:
a sensor arranged to determine a location of the second end;
a transmitter arranged to transmit a signal indicating the location; and,
a power source.

15. The protective helmet as recited in claim 14 , further comprising a plurality of piston devices arranged between the inner and outer shells, wherein each of said plurality of piston devices comprises:
a first component connected to the second end; and,
a second component.

16. The protective helmet as recited in claim 15 , wherein the second component comprises:
a dashpot;
an arm including a plurality of notches, the arm slidingly engaged with the dashpot; and,
a barrier including a plurality of doors.

17. The protective helmet as recited in claim 16 , wherein the first component is a cylinder and is operatively arranged to:
move axially along the barrier;
pass through the plurality of doors; and,
engage the plurality of notches.

18. The protective helmet as recited in claim 14 , further comprising a plurality of brackets connected to said first outer surface, said second inner surface, or both said first outer surface and said second inner surface, wherein said plurality of brackets are operatively arranged adjacent to said plurality of sinusoidal springs to limit with a lateral and torsional movement of said plurality of sinusoidal springs.

19. The protective helmet as recited in claim 14 , wherein:
the sensor is arranged to determine an extent of displacement of the second end; and, the transmitter is arranged to transmit a signal indicating the extent to the remote receiver.

20. A protective helmet having multiple protective zones, comprising:
an inner shell having a first inner surface and a first outer surface;
an outer shell having a second inner surface, a second outer surface, and at least one window defined by said outer shell, said outer shell functionally attached to said inner shell;
an elastomeric zone between said first outer surface and said second inner surface;
a plurality of sinusoidal springs positioned in said elastomeric zone, each of the plurality of sinusoidal springs comprising:
a first end; and,
a second end;

a plurality of piston devices arranged between the inner and outer shells, wherein each of said plurality of piston devices comprises:
a first component connected to the second end; and,
