Abstract

Claims (39)

1 . A protective sports helmet to be worn by a player, the protective sports helmet comprising:

an outer shell;

a multi-layer liner assembly disposed within the outer shell, the multi-layer liner assembly including an inner-layer, a middle-layer, and an outer-layer;

wherein the inner-layer is positioned adjacent to the player's head when the protective helmet is worn by the player, and wherein said inner-layer has: (i) a first density, and (ii) a first thickness at a first location;

wherein the outer-layer has: (i) a second density that is greater than the first density of the inner-layer, and (ii) a second thickness at a second location and a third thickness at a third location, and wherein the second and third thickness are different; and

wherein the middle-layer is positioned between an extent of an outer surface of the inner-layer and an extent of an inner surface of the outer-layer, and wherein said middle-layer has a fourth thickness at a fourth location that is less than each of the second thickness and the third thickness.

2 . The protective helmet of claim 1 , wherein the middle-layer does not continuously extend between a front region of the helmet, through a crown region of the helmet, and to a rear region of the helmet.

3 . The protective helmet of claim 1 , wherein the middle-layer has a periphery that is less than a periphery of the outer-layer whereby the middle-layer underlies less than 90% of the inner surface of the outer-layer.

4 . The protective helmet of claim 1 , wherein the inner-layer includes a segment with an outward extending projection and the outer-layer has a receiver that is configured to receive a portion of the projection.

5 . The protective helmet of claim 1 , wherein the multi-layer liner assembly further includes a comfort liner layer with an outer surface that is positioned adjacent to an inner surface of the inner-layer.

6 . The protective helmet of claim 1 , wherein the middle-layer has a third density that is greater than the first density.

7 . The protective helmet of claim 1 , wherein the inner-layer has a first chemical composition and the outer layer has a second chemical composition that is different from the first chemical composition.

8 . The protective helmet of claim 1 , wherein the middle-layer has a first chemical composition and the inner layer has a second chemical composition that is different from the first chemical composition.

9 . A football helmet to be worn by a player, the football helmet comprising:

an outer shell;

a multi-layer liner assembly disposed within the outer shell, the multi-layer liner assembly including an inner-layer, a middle-layer, and an outer-layer;

wherein the inner-layer is positioned adjacent to the player's head when the football helmet is worn by the player, said inner-layer: (i) including a first material, and (ii) having an inner-layer thickness at a first location;

wherein the outer-layer: (i) includes a second material that is different from the first material, (ii) has a first outer-layer thickness at a second location, and (iii) a second outer-layer thickness at a location in a crown region of the helmet that is different than the first outer-layer thickness, and wherein the outer-layer has a density that is different than a density of the inner-layer; and

wherein the middle-layer is positioned between an extent of an outer surface of the inner-layer and an extent of an inner surface of the outer-layer, and wherein said middle-layer: (i) includes a third material that is different from each of the first and second materials, and (ii) has a middle-layer thickness at a third location that is between the first and second locations, wherein the middle-layer thickness is less than each of the inner-layer thickness, the first outer-layer thickness, and the second outer-layer thickness.

10 . The football helmet of claim 9 , wherein the inner-layer includes a front segment positioned in the front region of the helmet and a rear segment positioned in a rear region of the helmet, and wherein the inner-layer lacks an extent that is positioned in the crown region of the football helmet.

11 . The football helmet of claim 9 , wherein the inner-layer includes a segment with an outward extending projection and the outer-layer has a receiver that is configured to receive a portion of the projection.

12 . The football helmet of claim 9 , wherein the outer-layer density is less than the inner-layer density.

13 . The football helmet of claim 9 , wherein the outer-layer density is greater than the inner-layer density.

14 . The football helmet of claim 9 , wherein the middle-layer has a density, and the inner-layer density is less than the middle-layer density.

15 . The football helmet of claim 9 , wherein the middle-layer has a density, and the outer-layer density is less than the middle-layer density.

16 . The football helmet of claim 9 , wherein the inner-layer has a hardness that is less than a hardness of the middle-layer.

17 . The football helmet of claim 9 , wherein the inner-layer has a hardness that is less than a hardness of the outer-layer.

18 . An American football helmet to be worn by a player, the football helmet comprising:

an outer shell;

a multi-layer liner assembly disposed within the outer shell, the multi-layer liner assembly including an inner-layer, a middle-layer, and an outer-layer;

wherein the inner-layer is positioned adjacent to the player's head when the football helmet is worn by the player, and wherein said inner-layer: (i) includes a first material, and (ii) has a segment with an outward extending projection;

wherein the outer-layer is positioned adjacent to an inner surface of the outer shell, and wherein the outer-layer includes: (i) a second material, and (ii) a receiver that is configured to receive a portion of the projection, and (iii) a first outer-layer thickness at a first location in a front region of the helmet that is different than a second outer-layer thickness at a second location in a crown region of the football helmet; and

wherein the middle-layer is positioned adjacent to an extent of an inner surface of the outer-layer, and wherein said middle-layer includes a third material that is different from both of the first and second materials.

19 . The American football helmet of claim 18 , wherein the inner-layer has a plurality of channels that extend completely through the inner-layer.

20 . The American football helmet of claim 18 , wherein the middle-layer does not continuously extend between the front region of the football helmet, through the crown region of the football helmet, and to a rear region of the helmet.
