Abstract: A seating arrangement in an aircraft passenger cabin includes rows of seats, one behind another at a prescribed seat pitch. A wider transverse aisle is formed between successive seat rows at a normal exit or an emergency exit. At least one seat row bordering on and facing the transverse aisle is equipped with foldable passenger seats that each have an upwardly tiltable seat bottom and armrests. By tilting up the seat bottom and the armrests, an enlarged width of the transverse aisle is provided in the event of an emergency evacuation. In normal operation, the prescribed transverse aisle width does not need to be maintained, i.e. can be reduced, so the seat bottom and armrests are tilted down into the normal-use position for a passenger to be seated on the seat. Thereby the seat pitch of this seat row can be reduced and the total seating capacity can be increased.

Abstract: Passengers are transported in a cabin of a passenger aircraft in an upright position. For this purpose the aircraft cabin is equipped with passenger stands. Each stand has a passenger backing and a safety belt, preferably a three-point safety belt. The stands are positioned in a standing room area of the cabin which has a sufficient vertical clearance between floor and ceiling for accommodating passengers in the upright position. The passenger backing has preferably a shell-shape forming a back support as a lean-against portion and at least one side portion for privacy. The shell or flat backing wall may itself be connected either directly or through a post for an angular adjustment relative to the forward flight direction.

Abstract: A storage compartment is combined with an air flow channel (5) between a passenger seat and an aircraft side wall in an aircraft cabin. The storage compartment is constructed of five walls forming a box (3) inserted into the air channel that extends longitudinally along the aircraft side wall and along the cabin floor. The box (3) is upwardly closed by a hinged cover (16) forming a tray (17). The aircraft side wall (2) has at least one air filter element (10) facing into the channel. One or more dado panels (7) with air flow passages (6) enclose the channel toward the cabin. A cabin floor (4) closes the channel (5) downwardly. One or more decompression flaps (15) in the floor (4) normally close the channel (5). Under normal operating conditions air flow into and out of the cabin passes around the box through the channel (5) and the filter element (10).

Abstract: A vacuum plumbing system especially in an aircraft equipped with jet engines, is provided with a tap air supply source (4) that receives the tap air from the engine exhaust and is connected with a nozzle (1A) of at least one ejector or jet air pump (1) while the suction port (1C) of the pump (1) is connected through ducts or pipes (7, 11, 12) to a refuse collecting duct (15) either directly or indirectly through refuse collecting tank (9). Filters in the tank and conveying pumps are thus avoided.
