Structure having an air chamber
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.
1. A construction comprising at least two air chambers which are enclosed by flexible flat material, wherein flexible crosspieces for stabilization of the outside shape of the at least two air chambers are arranged within the interior of each air chamber, and wherein at least one of the at least two air chambers in the inflated state forms a wall structure and the at least one other of said at least two air chambers forms a ceiling, and wherein the at least two air chambers in the inflated state form a self-supporting three-dimensional structure with side walls and ceiling, which in the inflated state forms a sleeping or resting berth for use in an aircraft, wherein the at least one air chamber forming the wall structure abuts the bottom of the at least one other of said at least two air chambers forming the ceiling with the upper face side, wherein the at least two air chambers consist of a translucent material such that light is emitted through said wall structure into said ceiling.
2. The construction as claimed in claim 1 , wherein the at least two air chambers comprise at least four separate air chambers that are plate-shaped.
3. The construction as claimed in claim 2 , wherein the ceiling comprises at least one additional air chamber.
4. The construction as claimed in claim 1 , wherein the at least one air chamber which forms the ceiling is connected by at least one seam to the at least one air chambers which forms the wall structure.
5. The construction as claimed in claim 1 , wherein the flexible crosspieces in the at least two air chambers run essentially in the vertical direction.
6. The construction as claimed in claim 1 , wherein the at least two air chambers are pressurized with a pressure of up to 150 mbar.
7. The construction as claimed in claim 6 , wherein the at least two air chambers are pressurized with a pressure of 50-90 mbar.
8. The construction as claimed in claim 1 , further comprising a floor shell with an upright wall shoulder onto which the wall structure is subsequently mounted.
9. An aircraft comprising a berth including at least one installed construction as claimed in claim 1 .
