Abstract
(EN)

An oxygen generator for use in a passenger aircraft comprises an oxygen generating substance for generating oxygen gas after being activated; an activating substance for activating the oxygen generating substance; a pyroelectric igniter for igniting the activating substance upon receiving an electric trigger input; a housing defining a gas-tight chamber, accommodating the oxygen generating substance, the activating substance and the pyroelectric igniter; at least two electric conductors, coupled to the pyroelectric igniter and extending through a passage in the housing between an interior of the gas-tight chamber and an exterior of the gas-tight chamber; and at least one of a gas-tight glass-to-metal sealing and a gas-tight ceramic-to-metal sealing, sealing the at least two electric conductors with respect to the housing at the passage.
