Systems for restraining palleted cargo within an aircraft are provided. A first system operates to provide vertical and outboard lateral support to cargo at a location where the opposite ends of the system are connected to surfaces that are aligned at different orientations, for example, one end connected to a horizontal floor and the second end connected to a sidewall of the fuselage of the aircraft. A second system operates to provide aft, vertical, and outboard lateral support to cargo upon a pallet proximate to its corner, and at a location where a portion of cargo extends above a stay out zone of the aircraft.

A fixed-wing cargo aircraft having a kinked fuselage is disclosed. The fuselage contains a continuous interior cargo bay, and includes a forward portion, an aft portion, and a kinked portion forming a junction in the fuselage between the forward and aft portions. The kinked portion contains a transition region of the cargo bay and defines a bend between a forward centerline and an aft centerline. The kinked portion is formed with a forward transverse frame section, a separate aft transverse frame section, and a plurality of longitudinal frame elements extending between the forward and aft frame sections, the forward frame being coupled to an aft end of the forward portion and the aft frame section being coupled to a forward end of the aft portion such that the aft frame section is angled with respect to the forward frame section about a lateral axis of the cargo aircraft.

A rail system, in particular for assembling or fastening seats in an aircraft, includes an assembly rail, in particular a seat rail for assembling or fastening a seat, a first panel, in particular a first floor panel for arrangement next to and substantially in parallel with the assembly rail, at least one cover element which is movable for covering the assembly rail, and a levelling device for levelling the upper surface of the first panel, in particular for levelling a recess or depression in said panel when the at least one cover element covers the assembly rail.

A vehicle cabin seat arrangement includes a seat rail having a first and a second side faces; a group of passenger seats held on the seat rail by holding devices resting on a top side of the seat rail; pluralities of first and second holding blocks arranged on the first and second side faces, respectively; and a plurality of stop blocks arranged on a bottom side of a holding device To every passenger seat two first or second holding blocks are assigned, between which a holding device coupled with the passenger seat is displaceable. The respective holding device, includes one of the stop blocks arranged on the bottom side of the holding device such that the stop block is bringable into contact with the two assigned holding blocks on moving the holding device on the seat rail. Passenger seats are alternatingly assigned with first and second holding blocks.

A seat system for a cabin of a transportation system includes a first seat unit, a second seat unit, and a rail system attachable to a floor of the cabin, having two rails that run parallel to each other, for receiving the seat units on selective positions. A line-up of a plurality of first seat units and at least one second seat unit on the rail system constitutes a seat arrangement. The first seat unit includes a seat frame having a seat cushion and a back cushion. The second seat unit includes a seat frame having a foldable seat cushion and a back cushion. The second seat frame includes two forward seat legs supported on two auxiliary rail segments that are arranged between the rails in a region. The forward seat legs are guidable underneath the seat cushion of a first seat unit arranged in front of it.

A cargo restraint assembly may comprise a first bracket slidingly coupled to a housing. A retention block may be pivotably coupled to the first bracket. A second bracket may be slidingly coupled to the housing. The first bracket may be coupled to the second bracket via a spring. The first bracket and the second bracket may be configured to attenuate in response to a cargo deck bending during transportation of cargo in an aircraft.

To reduce strain and mitigate fatigue in an aircraft's airframe, some example dynamic load-sharing systems provide the aircraft with multiple tension devices that share the weight of a load hanging from the aircraft. In some examples, the tension devices are installed in the aircraft's cabin space to protect the surrounding airframe by transmitting a portion of the load's weight directly from the floor to the ceiling of the aircraft. In some examples, the portion of the weight transmitted by the tension devices is proportional to the load's total weight. In some examples, the tension devices are piston/cylinder devices that are interconnected by a manifold to distribute the load equally among the tension devices. Some examples of dynamic load-sharing system include a pressure relief valve and/or an accumulator that limits the maximum load applied to each tension device.

A rail for the fastening of equipment elements, such as, in particular, seats, in aircraft, includes a holding region for connection to an equipment element of an aircraft, and a support region to fasten the rail to a carrier element of the aircraft. The rail has a metallic shell which is, for example, made of titanium and which is filled with a fiber-reinforced thermoplastic filler material which is reinforced by short fibers. To produce the rail, a metallic molded part is used as a casting mold and is filled, for example by injection, with the filler material and, after the rail has been produced, forms the metallic shell for the filler material.
