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).
