A storage compartment is combined with an air flow channel (,) between a passenger seat and an aircraft side wall in an aircraft cabin. The storage compartment is constructed of five walls forming a box (,) inserted into the air channel that extends longitudinally along the aircraft side wall and along the cabin floor. The box (,) is upwardly closed by a hinged cover (,) forming a tray (,). The aircraft side wall (,) has at least one air filter element (,) facing into the channel. One or more dado panels (,) with air flow passages (,) enclose the channel toward the cabin. A cabin floor (,) closes the channel (,) downwardly. One or more decompression flaps (,) in the floor (,) normally close the channel (,). Under normal operating conditions air flow into and out of the cabin passes around the box through the channel (,) and the filter element (,). Should a decompression occur the flap (,) is opened and pressure equalization is achieved by air flow through the openings in the cabin floor thereby bypassing the air filter element (,) for rapid pressure equalization in different spaces of the aircraft.

Storage compartment and venting channel combination in an aircraft cabin

An overhead luggage compartment for a passenger conveyance is secured to a fixed overhead structure by a single guide lever at each end of the movable trough that can be tilted up or down. Each guide lever has one end journalled to the fixed overhead structure and one end journalled to a respective side wall of the trough. Two gear sectors (6, 7) mesh with a common gear wheel journalled to the guide lever between the gear sectors which have a gear center coinciding with the journal axes of the journals that secure the guide lever. One gear segment is rigidly secured to the overhead structure. The other gear segment is rigidly secured to the trough sidewall. The gears control the up and down motion of the trough. A biasing spring and a shock absorber are also provided.

Overhead luggage compartment, especially for passenger aircraft

An overhead baggage compartment has a lowerable trough, especially for a passenger aircraft, wherein the trough is connected by two quadrilateral bellcrank type levers or links, with the side walls of the trough inside a box-like housing which is open at the bottom and also has two side walls. A substantial weight compensation is achieved by pneumatic springs, whereby each pneumatic spring (14) works on an adjustable attachment point on the corresponding quadrilateral bellcrank link through a guide roller 15. During loading of the trough 3, its weight is so determined and the pneumatic spring 14 is so swivelled by a weighing lever 13, that the guide roller 15 is placed on the corresponding quadrilateral bellcrank link at an attachment point chosen according to the determined weight. It is a special advantage that closing of the baggage compartment only requires a minimal manual force which is largely independent of the weight of the trough.
