Problems solved by technology
The disadvantage of using an emergency opening device with a safety pin is that, depending on the overall configuration of the overhead storage box and the resulting leverage conditions on the guided cables of the retention system, very high forces may be required to trigger the emergency opening device
Due to manufacturing and assembly errors, there may also be large deviations in the trigger force
Especially in the event of a fire in the overhead storage compartment, the emergency opening must be actuated by pulling the lowerable housing, smoke or flames could escape from the overhead storage compartment and injure the person actuating the emergency opening, this is Adverse
Finally, there is also the risk of inadvertently triggering the emergency opening device during normal operation of the overhead storage compartment

Embodiment Construction
[0040] The overhead storage box 10 shown in FIGS. 1 and 2 includes a lowerable housing 12 that includes a base 14 and two mutually opposite side walls 16 . The lowerable housing 12 is pivotable from its upper closed position shown in FIG. 1 , where it is received in the overhead bin shell 18 , to a lower open loading or unloading position shown in FIG. 2 . The overhead bin housing 18 is rigidly fastened to the ceiling structure of the aircraft cabin, not shown in the figures.
[0041] The lowerable housing 12 of the overhead storage box 10 is connected to the overhead storage box housing 18 by means of two holding systems 20 which are each arranged in the region of the side walls 16 of the lowerable housing 12 . Each retention system 20 includes a guide roller 22 secured to the overhead bin shell 18 . Cables 24 shown in FIG. 1 are guided on guide rollers 22 and provide the connection of the lowerable housing 12 to the overhead bin housing 18 . For the sake of clarity, the ca...

An emergency opening device (30) for an overhead storage box (10) having a lowerable housing (12), comprising a connecting element (32) capable of being connected to a holding system (20) for the holding system For fastening the lowerable housing to the part (18) fixed to the structure. The emergency opening device also comprises a locking device (34) connectable to the lowerable housing or to a part fixed to the structure, wherein the locking device is adapted to fasten the connection element (32) to the lowerable position in the locked position. The housing (12) is fastened to either the structure-fixed part (18) and in the unlocked position allows the coupling element (32) to be detached from the lowerable housing or the structure-fixed part (18).
Description
technical field [0001] The invention relates to an emergency opening device for an overhead storage box with a lowerable housing and to an overhead storage box equipped with such an emergency opening device. Background technique [0002] Overhead storage boxes with lowerable housings are now used in passenger aircraft, not least because they advantageously allow an optimal use of space while also being extremely easy to operate. The lowerable housing pivots from an upper closed position to a lower open loading or unloading position, where it ensures optimum head freedom for passengers seated under the overhead storage bins. Even relatively short persons can comfortably access luggage items to and from the housing in the loading or unloading position of the housing. [0003] Such overhead storage bins typically include a retention system for pivotally securing the lowerable housing to a component fixed to a structural member, such as an overhead storage bin enclosure and / or ...
