A gravity-assisted tracking base assembly for an aircraft seat includes base rails mounted to floor tracks in an aircraft cabin by floor track fittings in fixed positions, the base rails connected by a tracking member for providing longitudinal tracking while minimizing added height. The base rails include tracking slots extending longitudinally, and the tracking member includes tracking elements translatable forward and backward along the tracking slots, allowing an aircraft seat mounted to the tracking member to translate forward and backward relative to the base. The tracking member includes a locking mechanism for locking the tracking member and seat in intermediate positions within the tracking slots. The tracking slots may be oriented slightly downward from the horizontal to allow for gravity-assisted tracking or to counteract the nose-up flight angles associated with cruising altitude, providing for easier seat tracking.

Described are track fitting assemblies for passenger seats. Each track fitting assembly includes a track fitting main body and an anti-rattle shear body. The track fitting main body is connectable to a leg of the passenger seat and includes a forward end, an aft end, and at least one stud configured to engage a track. The anti-rattle shear body is positionable on the track fitting main body and is movable relative to the track fitting main body. The anti-rattle shear body includes a forward end, an aft end, and a plunger at the forward end and configured to engage the track. The anti-rattle shear body is connected to the track fitting main body such that the plunger of the anti-rattle shear body is forward of the forward end of the track fitting main body.

Systems for securing fixtures to the floor of a transportation vehicle. The securing system has a simplified structure comprising a securing device with two C-profiles comprising a web extending between a top plate and a bottom plate, the profiles being joined by an omega-shape fishplate. Vertical lateral walls formed by the webs of the profiles are perforated.

A passenger seat for an aircraft, including a bottom support configured to be connected to a floor of the aircraft, a seat pan frame, and a support structure interconnecting the seat pan frame to the bottom support, the support structure including a front support member pivotally connected to a front end of the seat pan frame, the front support member including a respective strut on each side of the seat pan frame, each respective strut having a bottom end rigidly connected to the bottom support and an opposed top end located under the seat pan frame, the bottom end being inwardly, downwardly and rearwardly offset with respect to the top end.

A seat rail assembly for fastening a seat assembly in a vehicle and a method for making such a seat rail assembly are described. The seat rail assembly includes a seat rail configured to fasten the seat assembly, the seat rail including a metal material. A fastening profile element of the seat rail assembly is configured to receive the seat rail, the fastening profile element being formed of a plastic material. The fastening profile element forms a receiving region, which is configured to receive the seat rail, and the seat rail includes a seat rail crown which is arranged in the receiving region of the fastening profile element such that a wall portion of the fastening profile element at least partly extends around the seat rail crown. The seat rail assembly may be used in an aircraft.

A track filler may include an elongated body. The body may include a first sidewall having a first top end and a first bottom end, and formed along a first side of the body, a second sidewall having a second top end and a second bottom end, and formed along a second side of the body, opposite the first sidewall, and a topwall joining the first top end and the second top end. The body may form at least a partially hollow interior portion, and may also include a plurality of periodic notches along the first bottom end of the first sidewall and the second bottom end of the second sidewall and extending toward the first top end and the second top end, respectively. The body may also include a plurality of periodic grooves extending partially through the topwall, wherein each of the grooves extend from a notch at the first top end to a corresponding notch at the second top end.

An anchor rail for an aircraft floor includes an upper flange with a guideway and two flange wings. The rail is formed of a beam and of an anti-corrosion protection. The beam is formed at least of a body made from a first material and defining the lower stiffening structure and an upper platform. The anti-corrosion protection wholly covers an upper face of the upper platform and therewith constitutes the upper flange of the rail, thus layered. The anti-corrosion protection is at least formed of a protective sheet made of a second material more resistant to corrosion than the first material and selected from a metal and a fiber-reinforced plastic composite material. Such a rail exhibits good corrosion resistance for modest cost.

A seat assembly, a multi-passenger vehicle, and a method for attaching seats to a floor of a vehicle that employ an electromagnetic coupling between the seats and the floor. A power supply supplies electricity to the electromagnetic coupling to secure the seats to the floor and is turned off to release the seats from the floor without tools or workers bending down below the seats to remove coupling devices. The seats can therefore be readily repositioned or rearranged to adjust the spacing between the seats. Resident induction coupling is included between the floor of the vehicle and the seats to provide wireless power to the seats.

A vibration-reducing insert is usable to reduce vibration or play between two metal aircraft components. The insert rotates on a fastener, and includes a shelf that projects into the gap and operates as an indexable cam to establish an appropriate compression in an engaged portion of the shelf.

An aircraft seat connector for mounting an aircraft seat to a mounting rail provided at a floor of an aircraft cabin comprises: a seat connection element for being mounted to the aircraft seat; and a base element for being mounted to the mounting rail. The base element comprises a seat coupling portion which is configured for receiving a mating portion of the seat connection element in at least two different spatial orientations, with the seat coupling portion thus allowing for arranging the seat connection element on the base element in at least two different spatial orientations.
