Universal oxygen mask bayonet and bayonet receiver deflector

1. Field of the Invention 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.
