Survival Helmet Device

A survival helmet device for use in combination with a survival suit, and said survival helmet device comprising:

• a helmet surrounding an internal cavity and having an opening that is sized for passage of a user's head therethrough and into the internal cavity, and said helmet being securable to the survival suit;
• an inhale control valve surrounding an inner channel extending between a top end and a bottom end of said inhale control valve;
• an inlet opening formed by said inhale control valve approximate said top end for permitting atmospheric air to flow into said inner channel and a one-way inhale valve approximate said bottom end that is structured and disposed for permitting passage therethrough of air that is directed into the inner channel from the top end of said inhale control valve;
• an inhale control member on said inhale control valve that is manually operable between an open position and a closed position for selectively permitting or preventing the passage of airflow through the inlet opening;
• an inhale hose member in the internal cavity of said helmet, and said inhale hose member being secured to the bottom end of said inhale control valve at an inhale opening on said helmet;
• a mouthpiece in fluid flow connection with said inhale hose member and an exhale hose member, and said mouthpiece forming a breathing port that is sized and configured for selective connection with the user's mouth;
• an exhale control valve surrounding an inner cavity extending between a top end and a bottom end of said exhale control valve and said exhale hose member being located in the internal cavity of said helmet and being secured to the bottom end of said exhale control valve at an exhale opening on said helmet;
• an outlet opening formed by said exhale control valve approximate said top end for permitting air to flow from said inner channel into the atmosphere and a one-way exhale valve approximate said bottom end that is structured and disposed for permitting passage therethrough of air from said exhale hose member into said inner cavity of said exhale control valve;
• an exhale control member on said exhale control valve that is manually operable between an open position and a closed position for selectively permitting or preventing the passage of airflow through the outlet opening;
• at least one air cavity pocket secured to the inner facing surface of the survival suit;
• a T-connector on said exhale hose member and a tube member having a first end extending from said T-connector and a second end extending from said at least one air cavity pocket, said tube member and said at least one air cavity pocket being in fluid flow communication with said exhale hose member;
• a flap valve member on said at least one air cavity packet being operable to permit one-way entry of air into said at least one air cavity packet and a release valve member on said at least one air cavity packet that is operable to permit one-way exit of air into the survival suit;
• wherein the user may selectively position each of said inhale and exhale control members in the open and close positions and selectively open and close said flap valve member and said release valve member to control air supply and buoyancy within said survival helmet device and the survival suit.
