A visor assembly for an aviation helmet includes a lens, lens/strap anti-tear interface assemblies, retainer plates, and attachment strap assemblies. A friction strip mounted on the brim of the helmet operates to increase the friction between the visor lens and the helmet. The combined function of the friction strip and the configuration of the strap assemblies operate to maintain the visor in a deployed (as-worn) positioned in front of the wearer's face, even during high speed wind blasts of up to 600 KEAS (Knots Equivalent Air Speed).

A universal oxygen mask bayonet and bayonet receiver deflector includes a bayonet receiver deflector disposed on the helmet between the bayonet receiver and helmet, and a bayonet deflector connected to the oxygen mask bayonet. The bayonet receiver deflector includes a contoured side for providing a smooth transition between the helmet and the bayonet receiver on at least one side of the bayonet receiver. The oxygen mask bayonet deflector is made of two parts consisting of a bayonet ramp deflector and a bayonet tab deflector. The bayonet ramp deflector includes a ramped side and the bayonet tab deflector is generally frusto-conical in shape and includes a stem and a notch on the stem. The contoured side of the bayonet receiver deflector, the ramped side of the bayonet ramp deflector and the frusto-conical shape of the tab deflector cooperate to eliminate all potential hang up points and thereby parachute riser and/or shroud line entanglement with the oxygen mask bayonet, bayonet tab and the bayonet receiver during pilot ejection.
