Abstract
An improved helmet padding includes a multi-layered liner including an innermost layer consisting of a comfort liner designed to engage the head of the user, and having an outer surface covered by an inner surface of a relatively low density foam layer. The relatively low density foam layer consists of a first region of relatively uniform thickness with an outer area from which a multiplicity of protuberances extend radially outwardly. The radially outward layer of the inventive padding consists of a layer of relatively high density foam. The outer layer includes a plurality of recesses corresponding to the protuberances of the inner layer and sized to snugly receive the conical protuberances therewithin. The outer surface of the outer foam layer is shaped and configured to engage the outer shell of a helmet in which it is installed.
Claims27
An improved helmet padding for engagement within the outer shell of a helmet, the helmet padding comprising:
- an inner layer of foam padding and an outer layer of foam padding, the inner layer of foam padding including an inner surface and an outer surface, said outer surface of said inner layer defining a plurality of integrally formed conical protuberances, said inner layer of foam padding having a density relatively lower than density of said outer foam layer, said outer layer of foam padding including an inner surface and an outer surface, said inner surface of said outer layer defining a plurality of conical recesses, each of said conical recesses sized to receive, with surface contact, one of said conical protuberances;
- and
- said inner and outer layers being assembled together with said outer surface of said inner layer engaging said inner surface of said outer layer and with said conical protuberances received within respective ones of said conical recesses.
An improved helmet padding for engagement within the outer shell of a helmet, the helmet padding comprising:
- a) an inner layer of foam padding including an inner surface and an outer surface, said outer surface defining a plurality of integrally formed conical protuberances, said inner layer of foam padding having a density of 25 to 50 kg/m3;
- b) an outer layer of foam padding having a density of 60 to 90 kg/m3 and including an inner surface and an outer surface, said inner surface of said outer layer defining a plurality of conical recesses, each of said conical recesses sized to receive, with surface contact, one of said conical protuberances;
- c) said inner and outer layers being assembled together with said outer surface of said inner layer engaging said inner surface of said outer layer and with said conical protuberances received within respective ones of said conical recesses;
- and
- d) a comfort liner engaging said inner surface of said inner layer, said comfort liner having an inner surface adapted to engage a user's head.
A protective helmet comprising:
- a hard outer shell surrounding a multilayer foam padding structure, the multilayer foam padding structure including an inner foam layer disposed adjacent an outer foam layer;
- wherein said inner foam layer includes an inner surface and an outer surface, said outer surface of said inner foam layer defining a plurality of integrally formed conical protuberances, and said inner foam layer having a density relatively lower than density of said outer foam layer;
- wherein said outer foam layer includes an inner surface and an outer surface, said inner surface of said outer foam layer defining a plurality of conical recesses, each of said conical recesses sized to receive, with surface contact, one of said conical protuberances;
- wherein said inner and outer foam layers are assembled together with said outer surface of said inner foam layer engaging said inner surface of said outer foam layer and with said protuberances received within respective ones of said recesses, and said outer surface of said outer foam layer engaging said hard outer shell.
