Background Art

[0002] Fixings in the floor area of ​​an aircraft cabin are arranged for mounting cabin interior equipment, such as passenger seats. An example of such a fixing is a so-called seat track. A longitudinal profile with a defined cross section is provided, which allows the clamping of seat leg fittings along the track. The upper part of the seat track provides a recess or protrusion for the form-fitting engagement of the fitting. Since the provided tracks may be arranged throughout the cabin space, their upper profiles should be flush with the adjacent floor panels to avoid obstructions to passengers in areas where the seat tracks are not used to fix seats. Although the seat track should be light and allow the releasable mounting of equipment, such as passenger seats, in various positions along the track, there is an increasing demand regarding the sealing capability along the seat track. Summary of the invention

[0003] Therefore, there may be a need for a lightweight fixing interface with improved sealing.

Figure 1b The side view schematically shows Figure 1a The fixing interface 10 can be adapted to include a plurality of connecting posts 12. The connecting posts 12 include a mounting foot region 14 and a connecting head region 16, such as Figure 1a The mounting foot region 14 is configured to be inserted into one of a plurality of interface points in a floor assembly (see also Figure 2 The connector region 16 is configured to be engaged by a fitting of equipment to be secured to the floor installation. The connecting post 12 is configured to be releasably connected to an adjacent interface point in the floor installation, thereby providing a longitudinally extending fixed interface section for installation of equipment.

[0051] The interface point in the floor device can be set to floor device interface point 18, also refer to Figure 2 The interface points may also be provided to perform other tasks, such as serving as interface points for connecting the corrugated floor panels to the floor support structure.

[0052] The term "fixing interface" relates to a device that provides a mechanical interaction for mounting a component to a cabin floor. A component can be releasably fixed by means of an interface. A fixing interface may also be referred to as a fixing device, a mounting interface, a mounting device, a connecting interface or a connecting device.

[0053] The term "adaptable" relates to the option of providing joining sections of connecting posts only where needed.

[0054] The term “aircraft cabin floor” relates to a floor within an aircraft cabin, for example in the fuselage of an aircraft which separates a cabin area from a cargo area arranged below the cabin area.

[0055] The term "connection post" relates to a pin-shaped element that can be inserted into a recess of a floor support to serve as a connection interface. The post can also be referred to as a bolt or a pin. Thus, the connection post can have an insertion direction or an installation direction. In an option, the insertion direction or the installation direction is aligned with the Z direction in the aircraft during installation, i.e. assembly.

[0061] The term "fixed interface section" relates to an interface provided by several connecting columns, which interface can receive fittings for fixing the device, etc. The term "section" means a linear arrangement along the interface point, and more sections can also be provided. The section forms a kind of track section. Therefore, several sections form a virtual track with track sections, i.e. track segments, and intermittent track sections, i.e. intermittent track segments.

[0062] The term "equipment" refers to seats, cubical objects, toilets, galleys and other components arranged in the cabin space.

[0066] In an option, the connecting posts are configured to form the track. However, since the track is adjusted so that interfaces are provided only where required, a significant weight saving is provided. The supporting floor structure can be said to play the role of providing the main structure of the track, while the connecting posts provide the joint profile sections.

[0067] The advantage of this track-type profile is exploited, namely the ease with which fittings can be connected along small pitches, thereby allowing greater freedom in the location of attachment, while eliminating the disadvantage of incurring weight along the entire length.
