CAPACETE COM SUPRIMENTO DE AR. é descrito um capacete com suprimento de ar (10) que tem um visor (14), uma vedação da face (12) que inclui um elemento de armação (16) e um elemento de vedação (18). O elemento de armação (116) pode ser preso no visor (14) por encaixe por atrito. O uso de encaixe por atrito, opostos a pinos, adesivos e prendedores tipo velcro, pode reduzir o número de partes, pode permitir instalação e/ou remoção da vedação da face de uma maneira menos onerosa, e pode reduzir a oportunidade de falha do prendedor.HELMET WITH AIR SUPPLY. An air-supplied helmet (10) having a visor (14), a face seal (12) including a frame member (16) and a sealing member (18) is described. The frame member 116 may be attached to the viewfinder 14 by frictional engagement. The use of friction fit, as opposed to pins, adhesives and velcro fasteners, can reduce the number of parts, may allow installation and / or removal of the face seal in a less costly manner, and may reduce the chance of fastener failure. .
