Abstract

Abstract A mounting system for mounting a face guard on a football helmet, wherein the face guard is able to pivot about a horizontal axis about the top portion of the helmet. The improved mounting arrangement includes a pair of straps in the form of loops which enclose wire segments of the face guard. The straps are mounted to be in tension when the face guard encounters a frontal force. The straps are comprised of a resilient polyurethane material and are dimensioned so that most of the shock force encountered by the face guard due to blows thereon is absorbed by the tension mounted straps. The straps include a tapered end portion and an enlarged neck portion to provide sufficient resiliency yet sufficient rigidity to protect the player and to prevent the face guard from being permanently distorted. The head portions of the straps are dimensioned so that the face guard, in case of an injury to the player, can be pivoted past the head portions about the horizontal axis without distortion of the face guard. Since the face guard is mounted sufficiently far back on the helmet, a universal size face guard can be utilized.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 171 words
In a helmet including a pair of ear holes and a grid-like face guard, first mounting means for attaching the guard to the front of a helmet and for permitting said guard to pivot about a horizontal axis away from said helmet, the improvement comprising: a plurality of second mounting means for attaching the sides of said guard to the sides of said helmet, said second mounting means being in tension when said guard encounters a frontal force, the sides of said guard being attached to said second mounting means at points spaced a distance in the range of 1.5 inches to 2.0 inches from the centers of said ear holes, said second mounting means including a head portion, said head portion being dimensioned in a direction perpendicular to the surface of said helmet a distance sufficiently small to permit said guard to clear said head portion without distortion of said guard when said guard is disengaged from said plurality of second mounting means and is pivoted about said horizontal axis.
Claim 2
Dependent Claim 171 words
In a helmet including a pair of ear holes and a grid-like face guard, first mounting means for attaching the guard to the front of a helmet and for permitting said guard to pivot about a horizontal axis away from said helmet, the improvement comprising: a plurality of second mounting means for attaching the sides of said guard to the sides of said helmet, said second mounting means being in tension when said guard encounters a frontal force, the sides of said guard being attached to said second mounting means at points spaced a distance in the range of 1.5 inches to 2.0 inches from the centers of said ear holes, said second mounting means including a head portion, said head portion being dimensioned in a direction perpendicular to the surface of said helmet a distance sufficiently small to permit said guard to clear said head portion without distortion of said guard when said guard is disengaged from said plurality of second mounting means and is pivoted about said horizontal axis.
Claim 3
Dependent Claim 53 words
The helmet according to claim 1 wherein each said second mounting means includes a strap means, said strap means including a loop for encircling a wire member of said guard, the centerline of said loop spaced from the surface of said helmet a distance in the range of 0.300 inch to 0.380 inch.
Claim 4
Dependent Claim 30 words
The helmet according to claim 1 wherein the second mounting means is formed of a polyurethane material with a tensile strength in the range of 6000 psi to 6500 psi.
Claim 5
Dependent Claim 46 words
The helmet according to claim 2 wherein said mounting means includes a neck portion interconnecting said head portion and said loop, the length of said neck portion in the direction from said head to said loop being in the range of 0.188 inches to 0.219 inches.
Claim 6
Dependent Claim 16 words
The helmet according to claim 2 wherein said second mounting means is formed of clear polyurethane.
Claim 7
Dependent Claim 33 words
The helmet according to claim 1 wherein said second mounting means includes a loop portion, the portion of said loop opposite said head portion being tapered in the lengthwise direction of said strap.
