Protective helmet pad interface structure

Abstract

A shock-absorbing, protective interface pad structure usable between the shell of a helmet and the head of a helmet wearer including (a) an acceleration-rate-sensitive, viscoelastic core structure made of a product having substantially the same characteristics as at least one of Confor CF-42 or Confor CF-45 manufactured by EAR Specialty Composites in Indianapolis, Ind., and (b) a water-moisture-blocking, bidirectionally gas-permeable barrier layer spray-applied to and fully enclosing the core structure, made of the a product having substantially the same characteristics as the product manufactured, and designated V-2000, by Russell Products Company, Inc. in Akron, Ohio.

1 . A shock-absorbing, protective interface pad structure usable between the shell of a helmet and the head of a helmet wearer comprising
 an acceleration-rate-sensitive, viscoelastic core structure made of a product having substantially the same characteristics as at least one of Confor CF-42 or Confor CF-45 manufactured by EAR Specialty Composites in Indianapolis, Ind., and   a thin and flexible, water-moisture-blocking, but gas-permeable barrier layer spray-applied to and fully enclosing said core structure, made of the a product having substantially the same characteristics as the product designated V-2000 by Russell Products Company, Inc. in Akron, Ohio, completely blocking outside access to the core of all water moisture while accommodating substantially free, bidirectional gas breathability by the core structure.   
   
   
       2 . The interface pad structure of  claim 1  which possesses a body-facing side intended to face a helmet-wearer's head, and which further comprises an expanse of a moisture-wicking material made of a product having substantially the same characteristics as the product sold as Orthowick designated VELCRO® brand Loop 3993 by Velcro Laminates, Inc. in Bristol, Ind., with said expanse having a configuration which is one of (a) substantially completely enveloping the barrier-layer enclosed core structure, or (b) disposed across said pad structure's said body-facing side. 
   
   
       3 . A shock-absorbing, protective interface pad structure usable between the shell of a helmet and the head of a helmet wearer comprising
 an acceleration-rate-sensitive, viscoelastic core structure made of at least one of the product designated Confor CF-42 or Confor CF-45 manufactured by EAR Specialty Composites in Indianapolis, Ind., and   a thin and flexible, water-moisture-blocking, but gas-permeable barrier layer spray-applied to and fully enclosing said core structure, made of the product designated V-2000 by Russell Products Company, Inc. in Akron, Ohio, completely blocking outside access to the core of all water moisture while accommodating substantially free, bidirectional gas breathability by the core structure.   
   
   
       4 . The interface pad structure of  claim 3  which possesses a body-facing side intended to face a helmet-wearer's head, and which further comprises an expanse of a moisture-wicking material made the product sold as Orthowick and designated VELCRO® brand Loop 3993 by Velcro Laminates, Inc. in Bristol, Ind., with said expanse having a configuration which is one of (a) substantially completely enveloping the barrier-layer enclosed core structure, or (b) disposed across said pad structure's said body-facing side.
