Abstract: Modules (30) include lateral bearing beams (32) for distributing cargo loads over a cargo compartment floor (4). Roller trays (34, 34', 34") are secured to and extend longitudinally between the beams (32). A tie-down support beam (38) is secured to and extends longitudinally between outboard portions of adjacent bearing beams (32). The support beam (38) is anchored to a rail (12) mounted in the floor (4). A side guide (40) is attached to of the bearing beams (32) and carries vertical restraint members (46) and a longitudinal restraint latch (48). Adjacent modules (30) are connected by slip joints (68). A cargo tray (80) has sloping sides (86) to conform to curving cargo compartment sidewalls (6). Slots (102) on the sides (86) engage the restraint members (46). The tray (80) has an outer shell (82) and a corrugated inner shell (90) with ridges which form support surfaces ( 98) coplanar with a peripheral horizontal lip (106).

Abstract: The passenger flying in today's high altitude commercial jet airplanes is generally seated in a pressurized compartment which in some airplanes has an overhead passenger service unit that houses emergency oxygen masks which are automatically deployed in the event of cabin depressurization. For high density abreast seating arrangements, the passengers seated in the aisle seats may be outside of the reach radius for the emergency oxygen mask drop zone from the overhead storage unit. Therefore, the present invention relates to apparatus comprising a spring cartridge extension device for laterally extending the required number of oxygen masks, upon release of the door to the oxygen mask container; and positioning them over the abreast seating arrangements, so that an oxygen mask is within the reach of each of the seated passengers.
