Abstract
An emergency oxygen system is provided for aircraft passengers. The system includes at least one oxygen mask (2), with a sensor (4) for detecting at least one breathing characteristic value of a passenger using this oxygen mask (2). A control unit (10) individually determines the oxygen requirement of the passenger on account of the detected breathing characteristic value. A dosing device (8) is actuated by the control unit (10). The dosing device (8) supplies an oxygen quantity corresponding to the determined oxygen requirement, to the oxygen mask (2).
Claims20
An emergency oxygen system for aircraft passengers, the system comprising:
- an oxygen mask;
- a sensor means for detecting at least one breathing characteristic value of a passenger using said oxygen mask;
- a control means for determining the oxygen requirement of the passenger based on the detected breathing characteristic value;
- and
- a dosing means actuated by said control means for supplying an oxygen quantity corresponding to the determined oxygen requirement to the oxygen mask.
A method for determining the oxygen requirement of an aircraft passenger with an emergency oxygen supply, the method comprising the steps of:
- providing a breathing mask with a sensor;
- detecting a breathing characteristic value of the passenger;
- and
- determining the individual oxygen requirement of the passenger based on the detected breathing characteristic value.
A method according to claim 16, wherein an oxygen requirement of the passenger is allocated to the lung characteristic value based on the flight altitude.
A passenger oxygen mask for an emergency oxygen supply, the mask comprising:
- a mask body;
- a breathing bag;
- an air mixing valve;
- and
- a sensor for detecting the vacuum acting on the air mixing valve within an interior of the oxygen mask.
