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 shear plunger which is a part of a fitting group which connects an aircraft seat to a seat track which is placed on the inside floor of the aircraft. The shear plunger has a flat transition area which is flat and which is formed between a second radiused surface and a second radiused transition surface, a first radiused transition surface which has a radiused form and which is formed between the first radiused surface and second radiused surface, the second radiused transition surface having a radiused form and which is formed between the flat transition area and the third radiused surface in order to provide maximum surface contact between the shear plunger and the seat track.

A seat actuation control system is disclosed. The seat actuation control system may permit multiple functions to be controlled by a single actuator. For example, a seat floor tracking function, and a seat pan track and swivel function may be individually controlled by a single actuator, such as a rotary actuator.

A system for securing a passenger seat to a track can include a fitting coupled with or forming a portion of the passenger seat; a shear plunger coupled with the fitting including a shear plunger body defining a shear plunger locking surface; a guide pin assembly that may include a guide pin movable along a lift axis between a retracted state and an extended state and a locking member extending laterally from the guide pin that may travel in response to a movement of the guide pin from the retracted state to the extended state and may engage the shear plunger locking surface in response to a rotation of the guide pin in the extended state; and a quick install tool operable to raise and twist the guide pin assembly such that the locking member is held in tension against the shear plunger locking surface.

The present invention concerns a mounting structure and arrangement. More particularly, but not exclusively, this invention concerns a mounting structure and arrangement for mounting aircraft furniture in an aircraft. The mounting structure comprises a first connection assembly configured for engagement with a first mounting track; and an associated first support. The first support is configured to abut the first mounting track at a location fore or aft of the first connection assembly. The provision of the support may reduce the number of connection assemblies required to properly secure an item of aircraft furniture in an aircraft cabin using the mounting structure.

A seat indexing system and method for an internal cabin of a vehicle include a seat assembly, and an indexing wheel coupled to the seat assembly. The indexing wheel is configured to be moved between a stowed position, in which the indexing wheel is disengaged from a seat track, and a deployed position, in which the indexing wheel engages the seat track.

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.

An aircraft seat may include an upper aircraft seat assembly, a lower aircraft seat assembly, and a frame actuation assembly configured to actuate the upper aircraft seat assembly relative to the lower aircraft seat assembly. The lower aircraft seat assembly may include at least one spring coupled to a foundation with a sloped actuation surface configured to cause the upper aircraft seat assembly to be at a decreased height when in a bed position. The compressing of the at least one spring may be configured to counterbalance a load within the aircraft seat and generate a controlled actuation of the upper aircraft seat assembly from an upright position to the bed position. A return force provided by the at least one spring may assist the frame actuation assembly during actuation of the upper aircraft seat assembly from the decreased height of the bed position to the upright position.

A seating assembly provides direct aisle access for each seat in a row by employing a seat angling with respect to a cabin centerline. The seat angling opens up an area behind each seat back. Seat density may be increased by staggering the seats such that the opened area behind a forward row may be used to provide an armrest for a passenger in a next row. Seat density may be even further increased by overlapping the assemblies (as seen facing the seat) such that: the armrest for the forward row seat overlaps the legroom of the next row seat.

Systems and methods are disclosed herein for an aircraft seat with a dual-function linear actuator. The linear actuator may activate a first adjustable feature by moving in a first direction, and the linear actuator may activate a second adjustable feature by moving in a second direction. The linear actuator may include a decoupling mechanism. The decoupling mechanism may decouple the first adjustable feature and the second adjustable feature from the linear actuator in response to loss of power to the linear actuator.
