Abstract
A protective helmet and insert for reducing the possibility or severity of a concussion are provided. The insert comprises a shock absorbing portion and a flexible liner portion, the shock absorbing portion to be disposed between a helmet shell and the liner portion. The shock absorbing portion can possess a substantially constant resistive deformation force characteristic for reducing the peak G-force applied to the head during an impact. The insert can comprise a plurality of flexible liner connectors for movably interconnecting the liner portion to a helmet shell to allow for the flexible movement of the liner portion relative the shell. The liner connectors can be in the form of vent shaft walls that each defines a vent shaft for providing fluid communication between a headspace of the liner and an outer side of the shock absorbing portion to ventilate the headspace. A helmet comprising the liner is also provided.

a first shock absorbing portion having a structure that is flexible, deformable, compressible, and capable of substantially recovering from a deformation, and further having a structure possessing a substantially constant resistive deformation force characteristic; and a flexible liner portion, the liner portion being disposed at or proximate the first shock absorbing portion, the liner portion having a thickness that is less than a thickness of the first shock absorbing portion, wherein when the insert is disposed in the helmet, the first shock absorbing portion faces an inner surface of the shell, and the liner portion faces a region of the helmet adapted to receive the head of a wearer.
2. The helmet insert of claim 1 wherein the first shock absorbing portion is in the form of visco-elastic polyurethane foam.
3. The helmet insert of claim 1 wherein the liner portion is in the form of closed-cell foam.
4. The helmet insert of claim 1 wherein the first shock absorbing portion has a thickness of at least 1.5 inches.
5. The helmet insert of claim 1 wherein the liner portion is a waterproof barrier.
6. The helmet insert of claim 1 wherein when the helmet insert is positioned on the head of a wearer, the first shock absorbing portion extends to substantially surround the forehead, left side, right side, and rear regions of the head.
7. The helmet insert of claim 1 wherein the first shock absorbing portion has an outer side and an inner side, the inner side facing the liner portion, wherein the liner portion has an outer side and an inner side, the outer side facing the first shock absorbing portion, and wherein the helmet insert defines at least one aperture therethrough extending between the inner side of the liner portion and the outer side of the first shock absorbing portion for providing fluid communication between the inner side of the liner portion and the outer side of the first shock absorbing portion.
8. The helmet insert of claim 7 further comprising fluid sealing for preventing the ingress into the first shock absorbing portion of any fluid disposed in or flowing through the at least one aperture.
9. The helmet insert of claim 8 wherein the fluid sealing is in the form of one or more vent shaft walls, each vent shaft wall defining a vent shaft therethrough, and being disposed in a one of at least one aperture in the first shock absorbing portion and extending between the inner side and the outer side of the first shock absorbing portion.
10. The helmet insert of claim 9 wherein a proximal end of the one or more vent shaft walls is connected to or is integrally formed with the liner portion.
11. The helmet insert of claim 10 wherein the one or more vent shaft walls are flexible and resilient.
12. The helmet insert of claim 10 wherein the one or more vent shaft walls are flexible, and wherein a distal end of the one or more vent shaft walls extends from the liner portion towards the outer side of the first shock absorbing portion, the distal end being connectable to the shell such that when the helmet insert is disposed within the shell, the one or more vent shaft walls moveably interconnect the liner portion with the shell, thereby allowing for limited and flexible movement of the liner portion relative to the shell.
13. The helmet insert of claim 12 wherein the distal end of the one or more vent shaft walls comprises a flange, the flange being connectable to the shell.
14. The helmet insert of claim 12 wherein when the helmet insert is disposed within the shell, the one or more vent shaft walls are aligned with one or more apertures in the shell to provide fluid communication between the inner side of the liner portion and the outer side of the shell for ventilating a headspace of the helmet.
15. A helmet insert disposable at an inner side of a shell of a helmet, the insert comprising:
a first shock absorbing portion having a structure that is flexible and deformable, the first shock absorbing portion having an outer side and an inner side;
a flexible liner portion, the liner portion being disposed at or proximate the inner side of the first shock absorbing portion;
a plurality of spaced apart flexible liner connectors, each liner connector comprising a proximal end connected to or integrally formed with the liner portion, each liner connector further comprising a distal end extending towards the outer side of the first shock absorbing portion, the distal end of each liner connector being connectable to the shell such that when the helmet insert is disposed within the shell, the liner connectors moveably interconnect the liner portion with the shell, thereby allowing for limited and flexible movement of the liner portion relative to the shell.
a first shock absorbing portion having a structure that is flexible and deformable, the first shock absorbing portion having an outer side and an inner side;
a flexible liner portion, the liner portion being disposed at or proximate the inner side of the first shock absorbing portion;

16. The helmet insert of claim 15 wherein the liner connectors are resilient.
17. The helmet insert of claim 15 wherein the structure of the first shock absorbing portion further possesses a substantially constant resistive deformation force characteristic.
18. The helmet insert of claim 17 wherein the first shock absorbing portion has a thickness of at least 1.5 inches.
19. The helmet insert of claim 15 wherein the liner portion is in the form of closed-cell foam.
20. A protective helmet having an outer portion, and an inner portion for receiving the head of a wearer, the helmet comprising:
an outer shell for circumscribing the head of the wearer;
a first shock absorbing portion disposed within the outer shell and having a structure that is flexible and deformable, the first shock absorbing portion having an outer side and an inner side, the outer side facing the outer shell;
