| titleOfInvention | Flexible multi-layer helmet and preparation method thereof |
| abstract | The present invention discloses a protective helmet that can include a shell and a multi-layer liner disposed within the shell and sized to receive a wearer's head. The multilayer liner may include an inner layer, an intermediate layer, and an outer layer. The inner layer may include an inner surface having an inner surface oriented toward an inner region of the helmet for receiving the wearer's head. The inner layer may comprise a medium energy management material with a density in the range of 40-70 g/L. The intermediate layer may be disposed adjacent the outer surface of the inner layer, wherein the intermediate layer comprises a low energy management material having a density in the range of 10-20 g/L. The outer layer may be disposed adjacent to an outer surface of the intermediate layer, the outer layer comprising an outer surface having an orientation toward the outer shell, wherein the outer layer comprises a density of 20-50 grams per liter (g/L). ) range of high energy management materials. |
