The invention relates to an oxygen supply unit equipped with an oxygen generator for supplying one or more oxygen masks. These masks and the generator are accommodated in an openable housing. The oxygen supply unit is improved in that a highest possible savings in weight is achieved while maintaining the stability of the entire arrangement so that oxygen generators can be installed which are useable for a longer duration. For this purpose, the oxygen generator is attached to a strut which is releasably connected to a reinforcing frame of the housing.

Oxygen supply unit having an oxygen generator

The invention relates to a protective hood having a viewing window and an oxygen mask equipped with a breathing-gas connection for an oxygen supply. The protective hood is improved in that the oxygen supply is first established unhindered and the protective hood can be pulled over the head with a reliable manual movement when required without the oxygen supply having to be interrupted. Such a protective hood is especially useable by passengers in an aircraft. The protective hood is packed such that the hood is rolled up toward the front in four mutually perpendicular directions in the direction of the breathing-gas connection for the oxygen mask so that a rip loop holds the rolled parts together by means of a VELCRO closure. The rip loop is attached to the hood in the region thereof corresponding to the nape of the neck. For the required situation and while the user holds the oxygen mask in place on the face, the user need only pull on the loop thereby causing the rolled hood to unfold and the edge of the hood can be simply pulled over the head.
