Universal oxygen mask bayonet and bayonet receiver deflector

A deflector for an oxygen mask bayonet and a bayonet receiver mounted on a helmet, the bayonet having a bayonet tab, the deflector comprising:

• a bayonet receiver deflector being disposed on the helmet between the bayonet receiver and helmet, said bayonet receiver deflector having a contoured side providing a smooth transition between the helmet and the bayonet receiver on at least one side of the bayonet receiver;
• a bayonet deflector connected to the oxygen mask bayonet and having surfaces providing a smooth transition between the oxygen mask bayonet, the helmet and the bayonet receiver deflector;
• wherein said contoured side and said surfaces cooperate to prevent parachute riser and/or shroud line entanglement with the oxygen mask bayonet, bayonet tab and the bayonet receiver during ejection.

An apparatus mounted on a helmet for deflecting parachute riser and shroud line entanglement with a lower edge of an oxygen mask bayonet receiver comprising:

• a bayonet receiver deflector forming a smooth transitional surface between the lower edge of the bayonet receiver and the helmet.

An apparatus mounted on the sliding release tab of an oxygen mask bayonet for deflecting parachute riser and shroud line entanglement with a lower edge of the bayonet comprising:

• a bayonet deflector attached to the bayonet tab and wrapping partially around the bayonet to form a sloping transitional surface at the lower edge while providing clearance for the sliding of the tab.
