Abstract

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 engagable 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.

First claim

What is claimed is:

1 . A liner assembly for a protective helmet comprising:
a wrap-around pad adapted to be engaged to the inner surface of the helmet, the wrap-around pad having a plurality of substantially circular cells spaced along a curved line 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 located off the curved line; a crown pad removably engagable to a crown portion of the inner surface; and two jaw pads, each removably engageable to a jaw flap, and each comprising one cell L-shaped cell; wherein each cell of each of said pads includes an outer sheet of thermoplastic welded around its perimeter to the perimeter of a second, inner sheet of thermoplastic, each inner sheet being adapted to engage the head of a player wearing the helmet and defines 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 contacting the inside of the helmet, each of the protrusions having an open base near the foam cushion and flat peak engaging the inside of the helmet, the base having a large diameter relative to the 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 to be engaged inside a helmet, the wrap-around pad having plural substantially circular cells spaced along a curved line around an inside of a helmet with the wrap-around pad, the wrap-around pad having at least one additional cell at each end of the curved line and one additional cell located off the curved line; a crown pad to be removably engagable in a crown portion of a helmet; and two L-shaped jaw pads to be removably engageable to a jaw flap of a helmet; each cell includes an outer sheet of thermoplastic welded around its perimeter to the perimeter of a second, inner sheet of thermoplastic; each inner sheet being for engaging a player's head wearing the helmet, and defining one enclosure for each cell; each cell containing a foam cushion and defining multiple spaced apart, outwardly-projecting hollow protrusions for contacting a inside of a helmet, each protrusion having an open base near the foam cushion and a flat peak for engaging an the inside of a helmet, the base having a large diameter relative to the 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.
