摘要:
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).

The invention relates to an oxygen breathing device, in particular for cockpit crew member of an aircraft, comprising a pressurized oxygen source for storing pressurized oxygen, an oxygen mask, adapted to fit to nose and mouth of a person to be supplied with oxygen from the pressurized oxygen source, an oxygen supply line connecting the pressurized oxygen source with the oxygen mask, a pressure regulator/safety valve coupled in the oxygen supply line to selectively open or shut off oxygen flow from the pressurized oxygen source to the oxygen mask and/or to control pressure of said oxygen supplied to the oxygen mask. According to the invention, such oxygen breathing device is improved by having a pneumatic seal adapted to pneumatically seal the pressurized oxygen source in a non-use condition, an opening device adapted to open the pneumatic seal in case of an emergency situation requiring oxygen supply to the person, a change over valve adapted to selectively supply oxygen from the pressurized oxygen source or pressurized air from a pressurized air source to the oxygen mask.
摘要:
The passenger oxygen mask is provided for emergency situations on board an aircraft. The mask body is designed collapsible at least in sections. An axial overall height of the mask body is reduced by way of the one or more mask sections. This simplifies the accommodation of the oxygen mask or even permits a smaller constructional size of the preparation device.
