Liner assembly for a protective helmet
View Patent ↗A liner assembly for a protective helmet has a wrap-around pad inside the helmet with plural circular cells spaced along a curved line, at least one additional cell at each end of the line and one additional cell located off the line. A crown pad removably engageable in a crown of the helmet and two L-shaped jaw pads removably engageable to jaw flaps of the helmet. Each cell includes an outer sheet welded around its perimeter to the perimeter of an inner sheet, each inner sheet engaging a player's head and defining one enclosure for each cell. Each cell containing a foam cushion and multiple spaced apart hollow protrusions contacting the inside of the helmet. Each protrusion has an open large diameter base near the cushion and flat smaller diameter peak engaging the helmet. Each protrusions also having a conical side wall tapering from base to peak.
1. A liner assembly for a protective helmet comprising:
a wrap-around pad adapted to be engaged to an inner surface of the helmet, the wrap-around pad having a plurality of circular cells spaced along a curved line configured to be around the inner surface, and at least one additional cell at each end of the curved line, the wrap-around pad also having one additional cell at each end of the curved line;
a crown pad removably engageable to a crown portion of the inner surface; and
two jaw pads, each jaw pad removably engageable to a respective jaw flap of the helmet, and each jaw pad comprising one cell having two curvilinear segments, the curvilinear segments meeting one another at an angle;
wherein each cell of each of said pads includes an outer sheet of thermoplastic welded around a perimeter of the outer sheet to a perimeter of a second, inner sheet of thermoplastic, each inner sheet being adapted to engage the head of a player when the player is wearing the helmet, and each inner sheet defining one enclosure for each cell;
wherein each cell of each of said pads contains a foam cushion; and
wherein each cell of each of said pads defines multiple spaced apart, outwardly-projecting hollow protrusions adapted to contact the inner surface of the helmet, each of the protrusions having an open base near the foam cushion and having a flat peak adapted to engage the inner surface of the helmet, the base having a larger diameter relative to a diameter of the peak, and each of the protrusions also having a conical side wall that tapers from the base to the peak.
2. The liner assembly of claim 1 , wherein the crown pad comprises 1-5 cells.
3. The liner assembly of claim 2 , wherein the crown pad comprises 3 cells.
4. The liner assembly of claim 1 , wherein there are 2-20 cells along the curved line.
5. The liner assembly of claim 4 , wherein there are 5-15 cells along the curved line.
6. The liner assembly of claim 1 , wherein there are 9 cells along the curved line.
7. The liner assembly of claim 1 , wherein the at least one additional cell at each end of the curved line is located above the curved line.
8. The liner assembly of claim 1 , wherein the at least one additional cell at each end of the curved line is located below the curved line.
9. A liner assembly for a protective helmet comprising:
a wrap-around pad adapted to be engaged with an inside of the helmet, the wrap-around pad having a plurality of circular cells spaced along a curved line configured to be around the inside of the helmet, the wrap-around pad having at least one additional cell at each end of the curved line and one additional cell at each end of the curved line;
a crown pad adapted to be removably engageable to a crown portion of the helmet; and
two jaw pads, each jaw pad having two curvilinear segments, the curvilinear segments meeting one another at an angle, each jaw pad adapted to be removably engageable to a respective jaw flap of the helmet;
each cell includes an outer sheet of thermoplastic welded around a perimeter of the outer sheet to a perimeter of a second, inner sheet of thermoplastic;
each inner sheet configured to engage a player's head when the player is wearing the helmet, and each inner sheet defining one enclosure for each cell;
each cell containing a foam cushion and defining multiple spaced apart, outwardly-projecting hollow protrusions for contacting the inside of the helmet, each protrusion having an open base near the foam cushion and having a flat peak for engaging the inside of the helmet, the base having a larger diameter relative to a diameter of the peak, and each of the protrusions also having a conical side wall that tapers from the base to the peak.
10. The liner assembly of claim 9 , wherein the crown pad comprises 1-5 cells.
11. The liner assembly of claim 10 , wherein the crown pad comprises 3 cells.
12. The liner assembly of claim 9 , wherein there are 2-20 cells along the curved line.
13. The liner assembly of claim 12 , wherein there are 5-15 cells along the curved line.
14. The liner assembly of claim 9 , wherein there are 9 cells along the curved line.
15. The liner assembly of claim 9 , wherein the at least one additional cell at each end of the curved line is located above the curved line.
16. The liner assembly of claim 9 , wherein the at least one additional cell at each end of the curved line is located below the curved line.
