Abstract
Abstract A thin flexible lightweight shoulder protection device for attachment to a shooter's garments to absorb rifle or similar firearm recoil loads. The device includes a flexible cover portion within which an energy absorbing pad is retained. The pad includes a flexible sealed envelope which houses an internal solid thermoplastic elastomer matrix which provides the device with its damping or energy absorbing capability. Retention means are provided for removably locating and securing the device at desired garment locations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
A recoil and shock eliminating device for use in protecting the shoulder of a person operating a rifle or shotgun-type firearm, said device comprising a body disposed within an exterior flexible fabric cover which is constructed to envelope the body and provide attachment means to facilitate releasably securing the device to an associated garment, said body consisting solely of a molded polyurethane elastomeric thermoplastic material that is entirely solid so as to have no internal voids in the material, with said material being capable of distorting in response to a recoil force of an operating firearm juxtapositioned thereagainst, and having sufficient structural integrity to prevent the butt of the firearm from bottoming out against the user's shoulder and thereby absorb and eliminate the recoil force and shock of the operating firearm to prevent injury to the operator and reduce operator's fatigue resulting from both single firing and sustained operation of the firearm, said material having a specific gravity range of approximately 1.02 to approximately 1.03 and having an elongation range of from approximately 300 percent to approximately 1,200 percent.
Claim 2
Dependent Claim
179 words
A recoil and shock eliminating device for use in protecting the shoulder of a person operating a rifle or shotgun-type firearm, said device comprising a body disposed within an exterior flexible fabric cover which is constructed to envelope the body and provide attachment means to facilitate releasably securing the device to an associated garment, said body consisting solely of a molded polyurethane elastomeric thermoplastic material that is entirely solid so as to have no internal voids in the material, with said material being capable of distorting in response to a recoil force of an operating firearm juxtapositioned thereagainst, and having sufficient structural integrity to prevent the butt of the firearm from bottoming out against the user's shoulder and thereby absorb and eliminate the recoil force and shock of the operating firearm to prevent injury to the operator and reduce operator's fatigue resulting from both single firing and sustained operation of the firearm, said material having a specific gravity range of approximately 1.02 to approximately 1.03 and having an elongation range of from approximately 300 percent to approximately 1,200 percent.
Claim 3
Dependent Claim
19 words
A device as set forth in claim 1 wherein said body is disposed in a sealed flexible internal envelope.
Claim 4
Dependent Claim
33 words
A device as set forth in claim 2 wherein said internal envelope is defined by a pair of opposing flexible thin sheets matingly secured to one another adjacent their respective outer peripheral edges.
Claim 5
Dependent Claim
51 words
A device as set forth in claim 1 wherein said cover is formed from a single elongated piece of flexible fabric folded upon itself and matingly assembled along its longitudinal edges to define an external envelope having a front face and a back face and within which said body is disposed.
Claim 6
Dependent Claim
29 words
A device as set forth in claim 4 wherein said front face and said back face are secured to one another long a line extending between said longitudinal edges.
Claim 7
Dependent Claim
35 words
A device as set forth in claim 1 wherein said cover defines a closed external envelope within which said body is carried and which includes a tongue portion upon which said attaching means is located.
Claim 8
Dependent Claim
45 words
A device as set forth in claim 1 wherein said cover defines a front face and a back face, and which includes attaching means operative to interact with said back face and an associated garment to effect releasable attachment of said device to said garment.
Claim 9
Dependent Claim
36 words
The invention according to claim 3 wherein said internal envelope comprises a pair of thin flexible sheets of plastic film matingly assembled to each other adjacent their respective outer peripheral edges by a heat sealing process.
