Abstract

A supplied air helmet 10 that has a visor 14, and a face seal 12 that includes a frame member 16 and a sealing member 18. The frame member 116 can be secured to the visor 14 by frictional engagement. The use of frictional engagement as opposed to pegs, adhesives, and hook and look type fasteners, may reduce the number of parts, may permit face seal installation and/or removal in a less onerous manner, and may reduce the opportunity for fastener failure.
