Abstract
Abstract Disclosed is a protective vest having a collar or neck guard intended for use with helmets and, optionally, with shoulder pads or harnesses, of the types worn by players in contact sports. The protective vest has a flexible body with shoulder portions between chest and back panels. Surrounding an opening for receiving a player's neck is a raised collar, integrally formed with the body, which has an upper ring-like surface for contacting the bottom edge of the player's helmet. When contacted by the player's helmet, the collar, formed of resilient material, is placed in energy-absorbing compression. Also, the chest and back panels surrounding the collar, also being made of resilient material, are placed in a tension and compression loading, to further aid in absorbing the loading applied to the collar. The body portion and, particularly, the chest and neck panels are pliable so as to conform to the topography of the player's upper torso and to frictionally engage the player's body and any clothing in contact with the player's body underneath the protective vest, so as to provide the frictional engagement necessary for efficient energy absorption.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
A protective device for use with helmets of the type worn by players in contact sports, comprising: a flexible body of resilient material having shoulder, chest and back portions covering substantial portions of the shoulders, chest and back of a player respectively, and having a raised resilient collar immediately adjacent a central portion of the device defining an opening for the head of a wearer of the device, said raised resilient collar integrally formed with and continuously joined to said chest and said back portions so as to transmit thereto forces applied to an upper surface of said raised collar by the bottom of a helmet worn by the wearer, said body having an inner surface for frictionally engaging the body of a wearer so as to maintain said device in a preselected position about the body of a wearer so that displacement of said raised resilient collar portion is resisted with a resilient bias force which maintains said collar portion in said preselected position about the body of a wearer.
Claim 2
Dependent Claim
171 words
A protective device for use with helmets of the type worn by players in contact sports, comprising: a flexible body of resilient material having shoulder, chest and back portions covering substantial portions of the shoulders, chest and back of a player respectively, and having a raised resilient collar immediately adjacent a central portion of the device defining an opening for the head of a wearer of the device, said raised resilient collar integrally formed with and continuously joined to said chest and said back portions so as to transmit thereto forces applied to an upper surface of said raised collar by the bottom of a helmet worn by the wearer, said body having an inner surface for frictionally engaging the body of a wearer so as to maintain said device in a preselected position about the body of a wearer so that displacement of said raised resilient collar portion is resisted with a resilient bias force which maintains said collar portion in said preselected position about the body of a wearer.
Claim 3
Dependent Claim
47 words
The protective device of claim 1 wherein said device is pliable so as to generally conform to the shoulders, chest and back of the wearer and garments in contact therewith, so as to increase the area of frictional engagement therewith when said device is placed under stress.
Claim 4
Dependent Claim
46 words
The protective device of claim 2 further comprising joining members joining said chest and back portions, so as to encircle the upper torso of the player with a compressive engagement so as to maintain said device in said preselected position about the body of the wearer.
Claim 5
Dependent Claim
27 words
The protective device of claim 3 wherein joining members comprise straps having first ends affixed to said chest portions and second ends affixed to said back portion.
Claim 6
Dependent Claim
24 words
The protective device of claim 3 wherein said joining members comprise side panels of resilient foam material intermediate said chest and said back portions.
Claim 7
Dependent Claim
28 words
The protective device of claim 1 wherein the chest portion thereof is comprised of two separable parts to provide ready placement about the upper torso of a wearer.
Claim 8
Dependent Claim
24 words
The protective device of claim 6 wherein said separable parts of said chest portion include releasable fasteners for releasably joining the separable portions together.
Claim 9
Dependent Claim
23 words
The protective device of claim 1 wherein said raised collar is comprised of plural layers of foam material having different compression-resisting resilient forces.
Claim 10
Dependent Claim
31 words
The protective device of claim 8 wherein said plural foam layers comprise foam layers of different densities, with a layer of lesser density adjacent the, upper surface of said raised collar.
Claim 11
Dependent Claim
34 words
The protective device of claim 1 wherein said raised collar is comprised of a unitary molded construction having differing density portions with a lesser density portion adjacent the upper surface of said raised collar.
Claim 12
Dependent Claim
35 words
The protective device of claim 1 further comprising layers of wear-resisting material on the upper surface of said raised collar, protecting said raised collar from wear caused by contact with the bottom of said helmet.
Claim 13
Dependent Claim
31 words
The protective device of claim 1 wherein said raised collar forms a generally V-shaped joinder with said back portion, said V-shaped joinder having an included angle not more than 90 degrees.
Claim 14
Dependent Claim
30 words
The protective device of claim 1 wherein said raised collar forms a generally V-shaped joinder with said back portion, said V-shaped joinder having an included angle greater than 90 degrees.
