Patent ID: 8316752

Claim:
A shock-attenuating assembly that is sufficiently flexible to wrap around any shaped structure, said assembly comprising, in combination, (a) a first film of flexible resin material, wherein said first film of flexible resin material is optionally water-impermeable or is optionally coated with a water-impermeable material; (b) a second film of flexible resin material, wherein said second film of flexible resin material is optionally water-impermeable or is optionally coated with a water-impermeable material, wherein said second film of flexible resin material has attached pockets spaced from each other along the second film; (c) the first film is attached to the second film via a plurality of seams, wherein the seams surround each of the spaced pockets in such a manner as to make the assembly sufficiently flexible to surround a structure of any shape; (d) each of the pockets is filled with a flowable shock wave attenuating material selected from the group consisting of volcanic foam glasses, perlite, vermiculite and pumice; and (e) wherein both the first film and the second film are sufficiently porous with respect to acoustic or shock waves or gas to allow the acoustic or shock wave to penetrate the film to reach the flowable shock wave attenuating material.
