Abstract

Abstract A shock attenuation system for headgear having an outer protective shell, the system comprising a liner adapted to be secured to the internal surface of the shell, the liner comprising a series of tubes of elastomeric material extending with their axes generally parallel to the internal surface of the shell, and generally parallel to one another. Each tube is open at an end thereof and is elastically deformable under loads applied against the side of the tube, whereby, with the headgear worn by a wearer and upon application of an impact load to the headgear, the tubes in the area of impact deform elastically under the applied load and attenuate the shock upon the wearer from the applied load.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 124 words
A shock attenuation system for headgear having an outer protective shell, said system comprising a liner adapted to be secured to the internal surface of the shell, said liner comprising a series of tubes of elastomeric material adapted to extend with their axes generally parallel to the internal surface of the shell, the tubes extending generally parallel to one another, each of said tubes being open at an end thereof and elastically deformable under loads applied against the side of the tube, whereby, with the headgear worn by a wearer and upon application of an impact load to the headgear, the tubes in the area of impact deform elastically under the applied load and attenuate the shock upon the wearer from the applied load.
Claim 2
Dependent Claim 124 words
A shock attenuation system for headgear having an outer protective shell, said system comprising a liner adapted to be secured to the internal surface of the shell, said liner comprising a series of tubes of elastomeric material adapted to extend with their axes generally parallel to the internal surface of the shell, the tubes extending generally parallel to one another, each of said tubes being open at an end thereof and elastically deformable under loads applied against the side of the tube, whereby, with the headgear worn by a wearer and upon application of an impact load to the headgear, the tubes in the area of impact deform elastically under the applied load and attenuate the shock upon the wearer from the applied load.
Claim 3
Dependent Claim 26 words
A shock attenuation system as set forth in claim 1 wherein the liner further comprises an inner layer of cushioning material engageable with the wearer's head.
Claim 4
Dependent Claim 21 words
A shock attenuation system as set forth in claim 1 wherein the tubes of the liner extend in side-by side relation.
Claim 5
Dependent Claim 22 words
A shock attenuation system as set forth in claim 3, wherein adjacent tubes of the liner are joined together at their sides.
Claim 6
Dependent Claim 25 words
A shock attenuation system as set forth in claim 3, wherein the tubes are laced together by lacing extending through the sides of the tubes.
Claim 7
Dependent Claim 25 words
A shock attenuation system as set forth in claim 1, wherein the liner further comprises a carrier sheet, said tubes being joined to said sheet.
Claim 8
Dependent Claim 26 words
A shock attenuation system as set forth in claim 1 wherein the liner further comprises means forming pockets at spaced intervals adapted to receive said tubes.
Claim 9
Dependent Claim 23 words
A shock attenuation system as set forth in claim 1 wherein the sides of the adjacent tubes of the liner are spaced apart.
Claim 10
Dependent Claim 26 words
A shock attenuation system as set forth in claim 1 wherein with the liner secured in the shell the axis of each tube extends generally vertically.
Claim 11
Dependent Claim 25 words
A shock attenuation system as set forth in claim 1, wherein the liner is engageable with and conformable to the internal surface of the shell.
