Abstract: A chemical oxygen generator with a chemical mass, which is accommodated inside a container, generates oxygen by a chemical reaction, and is held in the container by a gas-permeable fibrous material. The fibrous material is arranged around the chemical mass. The fibrous material is designed as a chemical sorption filter.

Abstract: The invention relates to a chemical oxygen generator having a chemical charge arranged within a housing. This chemical charge is brought to an exothermal oxygen-releasing reaction by an ignition device with the reaction running through the chemical charge in the form of a reaction front defining a surface and starting from the ignition-end wall of the housing. The oxygen generator has at least one reaction-control member arranged within the chemical charge. In one embodiment, the reaction-control member is disposed transversely to the direction of movement of the reaction front and overlaps a part of the surface of the reaction front. In another embodiment, the reaction-control member extends parallelly to the direction of movement of the reaction front. The oxygen generator of the invention is improved in that the oxygen flow and the duration of supply can be influenced beyond that obtained with a purely geometric extension of the reaction path.

The oxygen generator has at least one reaction-control member arranged within the chemical charge. A generator of this kind is improved in that the oxygen flow and the supply duration can be influenced by the material and/or the shape of the reaction-control member. The improvement is achieved in that one or more reaction-control members made of sheet metal are arranged parallel to the direction of movement of the reaction front. As an alternative, the reaction-control member can be configured in the form of a spiral conveyor which is made of sheet metal or a thermally-insulating material.
