Abstract

The Invention relates to a passenger cabin emergency oxygen device for an aircraft, comprising at least one electrically driven activation device for activating the emergency oxygen device, at least one energy storage device and a source of electrical energy. Said source of electrical energy and said energy storage device are coupled together for substantially constant energy transmission from the source of electrical energy to the energy storage device at a first energy level, an activation device and a controller are coupled together for signal transmission from the controller to the activation device, said activation device and said energy storage device are coupled together for energy transmission from the energy storage device to the activation device at a second energy level which is higher than the first energy level.
