Abstract
Abstract A moisture-barriered, body-contact protective interface structure including a core, viscoelastic, acceleration-rate-sensitive cushioning structure, and a moisture-barriering container surrounding the cushioning structure, with the container being operable to block the flow of moisture while accommodating gas breathability for the cushioning structure.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
93 words
A body-contacting interface structure comprising a core, viscoelastic, acceleration-rate-sensitive cushioning structure, formed of a compressible, non-springy, viscoelastic, urethane foam possessing a load-response behavior which (a) resists sudden-movement rapid compression, yet (b) is less resistive to slow-movement compression, wherein the urethane foam behavior is degraded when exposed to water-based moisture, and a moisture-barriering container surrounding and encapsulating said cushioning structure, operable to block the flow of all moisture from all regions outside said container to the inside thereof while accommodating bidirectional gas permeability of all non-water-based gases for the cushioning structure inside said container.
Claim 2
Dependent Claim
93 words
A body-contacting interface structure comprising a core, viscoelastic, acceleration-rate-sensitive cushioning structure, formed of a compressible, non-springy, viscoelastic, urethane foam possessing a load-response behavior which (a) resists sudden-movement rapid compression, yet (b) is less resistive to slow-movement compression, wherein the urethane foam behavior is degraded when exposed to water-based moisture, and a moisture-barriering container surrounding and encapsulating said cushioning structure, operable to block the flow of all moisture from all regions outside said container to the inside thereof while accommodating bidirectional gas permeability of all non-water-based gases for the cushioning structure inside said container.
Claim 3
Dependent Claim
15 words
The interface structure of claim 1 which further comprises a moisture-wicking structure surrounding said container.
Claim 4
Dependent Claim
99 words
A body-contacting interface structure comprising a core, viscoelastic, acceleration-rate-sensitive cushioning structure, formed of a compressible, non-springy, viscoelastic, urethane foam possessing a load-response behavior which (a) resists sudden-movement rapid compression, yet (b) is less resistive to slow-movement compression, wherein the urethane foam behavior is degraded when exposed to water-based moisture, a moisture-barriering container surrounding and encapsulating said cushioning structure, operable to block the flow of all moisture from all regions outside said container to the inside thereof while accommodating bidirectional gas permeability of all non-water-based gases for the cushioning structure inside said container, and a moisture-wicking structure surrounding said container.
Claim 5
Dependent Claim
99 words
A body-contacting interface structure comprising a core, viscoelastic, acceleration-rate-sensitive cushioning structure, formed of a compressible, non-springy, viscoelastic, urethane foam possessing a load-response behavior which (a) resists sudden-movement rapid compression, yet (b) is less resistive to slow-movement compression, wherein the urethane foam behavior is degraded when exposed to water-based moisture, a moisture-barriering container surrounding and encapsulating said cushioning structure, operable to block the flow of all moisture from all regions outside said container to the inside thereof while accommodating bidirectional gas permeability of all non-water-based gases for the cushioning structure inside said container, and a moisture-wicking structure surrounding said container.
