Abstract

En hjelm (10) med lufttilførsel har et visir (14) og en ansiktstetning (12) som er forbundet med visiret. Ansiktstetningen (12) har et tetningselement (18) og et rammeelement (16). Tetningselementet (18) strekker seg radielt innover fra rammeelementet (16) og har første og andre permeabilitetsområder (20 og 22). Det andre området (22) har større permeabilitet enn det første området (20). Bruk av en ansiktstetning (12) med differensiert permeabilitet muliggjør en styrt strøm av luft gjennom det indre av hjelmen (10).
