Embodiment Construction

[0013]Referring to the drawings in particular, the adaptation of the oxygen supply to the individual requirements of the passenger is effected according to the invention in that at least one oxygen mask 2, as well as a sensor means or sensor 4 for detecting at least one breathing characteristic value of a passenger using this oxygen mask 2, is provided in the emergency oxygen system. In the normal case, the emergency oxygen system comprises a multitude of oxygen masks 2, i.e. at least one for each passenger, wherein a sensor means is allocated to each oxygen mask 2 and detects at least one breathing characteristic value of the passenger who currently uses the associated oxygen mask 2. Furthermore, according to the invention, a control means or control unit 10 is provided which individually determines the oxygen requirement of the passenger on account of the detected breathing characteristic value. With this, preferably an individual control means 10 is allocated to each oxygen mask ...

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).

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority under 35 U.S.C. §119 of German Patent Application DE 10 2004 063 698.2 filed Dec. 28, 2004, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to an emergency oxygen system for aircraft passengers as well as a method for determining the oxygen requirement of an aircraft passenger with the emergency supply of oxygen, and an associated passenger oxygen mask.BACKGROUND OF THE INVENTION[0003]In aircrafts, emergency oxygen systems are provided for the supply of oxygen to the passengers in the case of a pressure drop. Known emergency oxygen systems comprise passenger oxygen masks which at a certain flight altitude are supplied with an oxygen quantity adapted to the flight altitude, or with an adapted oxygen flow.[0004]With regard to greater flight altitudes and new flight paths, an extended oxygen supply to the passengers is to be pr...
