Embodiment Construction

[0031] FIG. 1 shows a simplified version of an emergency oxygen device 100 in view (A) of FIG. 1 . The system may be implemented by a passenger service unit 1000 or by an arrangement similar to a plurality of oxygen supply devices on a ceiling panel along an aircraft cabin, for example, along a row or aisle of an aircraft cabin as shown in view (B) of FIG. 1 The arrangement of 1100.

[0032] The emergency oxygen unit 100 has an oxygen source 20, an activation assembly 40, and a plurality of oxygen masks 30, which will be described in more detail below. According to the main concept of the invention illustrated in FIG. 1 , the activation assembly 40 comprises an actuator 10 based on a shape memory material.

[0033] The chemical oxygen generator 21 shown in the figure can be used as an alternative to an oxygen pressure cylinder or similar device in the oxygen source 20 . The chemical oxygen generator is housed in a cylindrical type case in which a chemical such as sodium chlo...

Abstract

The invention relates to an emergency oxygen device for at least one passenger of an aircraft, comprising a chemical oxygen generator and / or oxygen pressure cylinder including an oxygen source and a starter unit adapted for initiating a reaction in said oxygen source producing oxygen, at least one oxygen mask each connected with the oxygen source such that an oxygen fluid flow from said oxygen source after said starter unit has initiated the reaction is receivable at the oxygen mask, an activation assembly for activating the starter unit, and whereby the activation assembly comprises an actuator assembly comprising a shape memory material based actuator. The invention further relates to a method for activating an emergency oxygen device for at least one passenger of an aircraft, initiating by means of a starter unit a reaction of an oxygen source producing oxygen, wherein a chemical oxygen generator and / or oxygen pressure cylinder includes the oxygen source, receiving at an oxygen mask an oxygen fluid flow from said oxygen source after said starter unit has initiated the reaction, wherein each of the oxygen masks is connected with the oxygen source, activating the starter unit by means of an activation assembly, whereby the passengers emergency release action and the reaction initiation of the source are coupled by means of a shape memory material based actuator of an actuator assembly, wherein the activation assembly comprises the actuator assembly.

Description

technical field [0001] The invention relates to emergency oxygen equipment for supplying oxygen to at least one passenger in an aircraft, comprising: a chemical oxygen generator and / or an oxygen pressure pump comprising a source of oxygen and a starter unit adapted to initiate a reaction in the source of oxygen to produce oxygen ; at least one oxygen mask, each oxygen mask is connected to an oxygen source, so that after said starter unit has initiated a reaction, the flow of oxygen fluid flowing from said oxygen source can be received at the oxygen mask; an activation assembly for Activate starter unit. The invention still further relates to an oxygen supply system and a method for activating emergency oxygen equipment for supplying oxygen to at least one passenger in an aircraft. Background technique [0002] These emergency oxygen units are used to provide oxygen to aircraft passengers in emergency situations such as depressurization or smoke on board. Typically, each ox...
