Protective helmet system |
摘要 |
A jaw piece is attachable to a base edge of the helmet. The jaw piece and a portion of the base edge of the helmet define a user viewing window. A first face shield is pivotable between an open position and a closed position extending across the viewing window. A seal is provided to engage with a perimeter of the viewing window when the first face shield is in the closed position. The attaching assembly for attaching the first face shield comprises a helmet cam having first helmet cam surfaces configured to releasably attach the first face shield to the protective helmet system and second helmet cam surfaces configured to releasably attach a second face shield to the protective helmet. The attaching assembly generates a first biasing force to bias the seal toward the perimeter of the viewing window when the first face shield is in the closed position.
