The invention relates to an aircraft seat attachment (100) including a body (20), a plunger (30), and an activation lever (50). The activation lever (50) includes a locking system (54) adapted to go from an open position corresponding to a free state of the activation lever (50) to a closed position corresponding to a locked state of the activation lever (50). The attachment also enables, in a locked state of said attachment, clamping of a seat rail between at least one boss (22) of said body (20) and the plunger (30), which includes a system (41) for maintaining by friction a force clamping the attachment to the rail in the locked state so that the activation lever (50) does not participate in maintaining said clamping force.

An embodiment of the invention relates to a system for receiving cargo or passengers in a vehicle. The system includes a bottom beam and several functional units, wherein each functional unit includes a floor segment and a seat row with several passenger seats being attached to the floor segment. Each functional unit is assigned to a pivoting device for pivoting the functional unit relatively to bottom beam. Another embodiment of the invention relates to a vehicle having such a system.

A tooling making it possible to mount a module directly in an aircraft without making any modifications to the module. This tooling is made up of upper beams connected to the structure of the aircraft, lower beams secured to the module, lift elements connecting the lower beams to the upper beams and a drive system. The lift elements can move along the upper beams. The drive system makes it possible to convey the module to its functional location in the aircraft, by moving it along the upper beams via the lift elements. The principle of this tooling is to suspend the module in order to ensure and control its movement in the aircraft.

Different advantageous embodiments provide a method and apparatus to increase a clearance of a cargo area of an aircraft. The apparatus and method may comprise an aircraft with a cargo area. A tray system may have a plurality of segment trays with each segment tray positioned between a plurality of floor beams located underneath a surface of the floor of the cargo area. A plurality of rollers in the tray system may be configured to allow an object to be moved across the cargo area.

A pallet system for a vehicle may include a cargo pallet having an orthogonal shape. A pallet adapter may be mounted on the cargo pallet. The pallet adapter may be sized and shaped complementary to the cargo pallet and may be attached to an upper side of the cargo pallet. The pallet adapter may include a panel assembly having frame members covered by one or more top skin panels and/or bottom skin panels. The pallet system may include one or more flight test equipment units mounted to the panel assembly.

A rail for an aircraft floor includes an upper plate for supporting a set of floor panels covering the plate, and a lower stiffening structure. The rail is formed by a beam and by an anticorrosion protection. The beam is at least formed by a body made of a first material and defining the lower stiffening structure and an upper platform. The anticorrosion protection fully covers an upper face of the upper platform and forms therewith the upper plate of the rail, thus layered. The anticorrosion protection is at least formed by a protective sheet made of a second material that is more corrosion resistant than the first material and is selected from a metal and a fiber-reinforced plastic composite material. Such a rail exhibits good corrosion resistance at a moderate cost.
