Football helmet with impact attenuation system
A protective football helmet is provided having a one-piece molded shell with an impact attenuation system. This system includes an impact attenuation member formed in an extent of the front shell portion by removing material from the front portion. The impact attenuation member is purposely engineered to change how the front portion responds to an impact force applied substantially normal to the front portion as compared to how other portions of the shell respond to that impact force. In one version, the impact attenuation member is a cantilevered segment formed in the front portion of the shell.
1. A football helmet to be worn by a player while playing football, the helmet comprising:
a one-piece shell including:
a crown portion defining an upper region of the shell;
a front portion extending generally forwardly and downwardly from the crown portion, the front portion including a lower frontal region that extends continuously along the front portion;
left and right side portions extending generally downwardly and laterally from the crown portion, each of the left and right side portions having an ear flap configured to overlie an ear of the player wearing the helmet;
a rear portion extending generally rearwardly and downwardly from the crown portion;
means for dynamically varying impact response of the shell when an impact is applied to the shell, wherein said means includes a cantilevered segment positioned adjacent to a gap formed in the shell above the lower frontal region; and,
wherein when an impact force is applied substantially normal to the front portion of the shell, the cantilevered segment changes how said front portion of the shell responds to said impact force as compared to how the left and right side portions respond to said impact force.
2. The football helmet of claim 1 , wherein the cantilevered segment has a base and a free end extending from the base, and wherein the free end terminates above the gap.
3. The football helmet of claim 2 , wherein the cantilevered segment formed in the front portion of the shell and an extent of a periphery of the cantilevered segment is defined by the gap.
4. The football helmet of claim 2 , wherein the base is a living hinge to facilitate elastic deformation of the cantilevered segment when said impact force is applied to the front portion of the shell.
5. The football helmet of claim 1 , wherein the gap has a U-shaped configuration.
6. The football helmet of claim 1 , wherein the cantilevered segment is elastically displaced inward toward the helmet wearer when said impact force is applied to the front portion of the shell.
7. The football helmet of claim 1 , further comprising a front pad secured to an inner surface of the helmet and extending across a majority of the front portion of the shell and underlying the cantilevered segment, wherein said impact force applied to the front portion causes the cantilevered segment to elastically deform and compress a first portion of the front pad while a second portion of the front pad remains substantially uncompressed.
8. The football helmet of claim 1 , wherein the lower frontal region of the front portion resists inward displacement when said impact force is applied to the front portion of the shell.
9. The football helmet of claim 1 , further comprising a protective face guard coupled to the shell.
10. A football helmet to be worn by a player while playing football, the helmet comprising:
a one-piece shell including:
a crown portion defining an upper region of the shell;
a front portion extending generally forwardly and downwardly from the crown portion, the front portion having a lower frontal shell region that is adjacent a lower frontal edge of the shell;
left and right side portions extending generally downwardly and laterally from the crown portion, each of the left and right side portions having an ear flap configured to overlie an ear of the player wearing the helmet, wherein the lower frontal edge extends continuously between the left and right side portions;
a rear portion extending generally rearwardly and downwardly from the crown portion;
an impact attenuation member formed in the front portion of the shell adjacent and above the lower frontal shell region, said impact attenuation member includes a cantilevered segment; and,
wherein an extent of the impact attenuation member is capable of being elastically displaced inward of the lower frontal shell region when an impact force is applied substantially normal to the front portion of the shell.
11. The helmet of claim 10 , wherein a the lower frontal shell region consists of an intermediate portion and opposed side portions, wherein the impact attenuation member overlies said intermediate portion.
12. The helmet of claim 10 , wherein the impact attenuation member includes a base that acts as a living hinge to facilitate elastic deformation of the cantilevered segment when said impact force is applied to the front portion of the shell.
13. The helmet of claim 10 , further comprising a front pad secured to an inner surface of the helmet and extending across a majority of the front portion of the shell and underlying the impact attenuation member, wherein said impact force causes the cantilevered segment to elastically deform and compress a first portion of the front pad while a second portion of the front pad remains substantially uncompressed.
14. The helmet of claim 10 , wherein the front portion of the shell includes a pair of front vent openings, and wherein the impact attenuation member is positioned between the front vent openings.
15. The helmet of claim 10 , wherein the lower frontal shell region resists inward displacement when said impact force is applied to the front portion of the shell.
16. The helmet of claim 10 , further comprising a protective face guard coupled to the shell.
17. A football helmet to be worn by a player while playing football, the helmet comprising:
a one-piece shell including:
a crown portion defining an upper region of the shell;
a front portion extending generally forwardly and downwardly from the crown portion, the front portion having a continuous lower frontal edge;
left and right side portions extending generally downwardly and laterally from the crown portion, each of the left and right side portions having an ear flap configured to overlie an ear of the player wearing the helmet, and wherein the continuous lower frontal edge extends between the left and right side portion;
a rear portion extending generally rearwardly and downwardly from the crown portion, the rear portion having a continuous lower rear edge;
a first impact attenuation member that includes a first cantilevered segment extending into the front portion of the shell above the continuous lower frontal edge;
a second impact attenuation member that includes a second cantilevered segment extending into the rear portion of the shell; and
a protective face guard coupled to the shell.
18. The helmet of claim 17 , wherein an extent of the first impact attenuation member is capable of being elastically displaced inward toward the helmet wearer when an impact force is applied substantially normal to the front portion of the shell.
19. The helmet of claim 17 , wherein a periphery of the cantilevered segments are defined by a gap formed in the shell.
20. The helmet of claim 17 , wherein the first cantilevered segment is formed in the front portion of the shell and wherein at least an extent of the first cantilevered segment is defined by a gap that is formed in the shell.
21. The helmet of claim 17 , wherein the second cantilevered segment is formed in the rear portion of the shell, and wherein at least an extent of the second cantilevered segment is defined by a gap that is formed in the shell.
22. The helmet of claim 17 , wherein the first impact attenuation member includes a base that acts as a living hinge to facilitate elastic deformation of the first cantilevered segment when an impact force is applied to the front portion of the shell.
