Abstract

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.
