Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
In a shielding device for protecting an object from an impinging shock wave, a series of adjacently oriented substantially coextensive shielding layers at least partially enclosing the object, at least one of said layers being inflatable to a predetermined internal pressure, inner layers fabricated of a relatively resilient material arranged on each side of said one layer, an outer layer adapted to be directly impinged by a shock wave, a relatively rigid layer for reinforcing the device, said outer layer comprising at least one member inflated to a preselected internal pressure, said outer layer comprising a plurality of spherical members having different resilient characteristics and said spherical members being of different sizes with the larger members being disposed outwardly from the smaller members.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
103 words
In a shielding device for protection from an impinging shock wave, a series of adjacently oriented substantially coextensive shielding layers, at least one of said layers being inflated to a predetermined internal pressure, inner layers of relatively resilient material on opposite sides if said one lAyer, an outer layer adapted to be directly impinged by the shock wave and a relatively rigid layer for reinforcing the device, said one layer including a plurality of inflated spherical members, said inner layers being formed of an elastomeric material, said outer layer being formed of a vulcanized elastomeric material and said rigid layer comprising corrugated members.
Claim 4
Dependent Claim
