Abstract: The invention comprises a structure having at least two separate air chambers (7) enclosed by flexible, flat material (8) and having flexible bars (9) in the interior thereof for stabilizing an external shape of the air chambers (7). The structure is characterized in that the air chambers (7) form a wall structure (4) in the inflated state. By means of such a wall structure (4)—preferably in conjunction with a corresponding ceiling structure (16)—lightweight berths (1), particularly for aircraft crew, flight passengers, or transported injured persons, can be set up quickly and simply.

Abstract: A protective helmet having an inner hood includes a spacer knitted fabric of a monofilament yarn. The hood is covered by a pneumatic central layer which can be pressurized by means of compressed air and can be inflated by means of an air pump which can be, for example, removed and provided with valves. An outer layer consists of an inner textile layer which lies over the pneumatic central layer, and plates which are fixed to the textile layer, for example by adhesion. The plates include, for example, of plastic, composite materials, or natural materials. The plates can be arranged in such a way that joints are created thereinbetween, the outer layer thus being provided with a certain elasticity in order to cater for different head shapes and sizes.
