Helmet with non-Newtonian fluid liner system
A helmet assembly that includes an outer shell having an outer surface and an inner surface and defines a shell interior, a pad system disposed in the shell interior, and at least a first bladder member positioned between the inner surface of the outer shell and the pad system. The first bladder member defines a bladder interior and a non-Newtonian fluid is disposed in the bladder interior.
1. A helmet assembly comprising:
an outer shell that includes an outer surface and an inner surface and defines a shell interior,
a pad system disposed in the shell interior, wherein the pad system includes at least first and second pad members, wherein the first pad member includes a first pocket that includes a non-Newtonian fluid disposed therein, wherein the second pad member includes a second pocket that includes a non-Newtonian fluid disposed therein, and
a first set of coil members that are disposed in the first pocket, wherein the first set of coil members are immersed within the non-Newtonian fluid in the first pocket, a second set of coil members that are disposed in the second pocket, wherein the second set of coil members are immersed within the non-Newtonian fluid in the second pocket.
2. The helmet assembly of claim 1 wherein the first pocket includes a plurality of cells defined therein, wherein each cell includes the non-Newtonian fluid disposed therein, wherein the second pocket includes a plurality of cells defined therein, and wherein each cell includes the non-Newtonian fluid disposed therein.
3. The helmet assembly of claim 2 wherein each cell has a honeycomb shape.
4. The helmet assembly of claim 3 wherein each cell defines a cell axis, and wherein the cell axes are oriented generally perpendicular to the inner surface of the inner surface of the helmet.
5. The helmet assembly of claim 1 wherein the first pocket comprises a first bladder member that comprises a polymer, and wherein the second pocket comprises a second bladder member that comprises a polymer.
6. The helmet assembly of claim 1 wherein the non-Newtonian fluid comprises corn starch and non-toxic antifreeze.
7. The helmet assembly of claim 1 wherein the first and second pad members are temporarily secured to the outer shell.
8. The helmet assembly of claim 7 wherein the first and second pad members are secured to the outer shell using hook and loop fasteners.
