A fastening system for a seat includes a base associated with the rest of the seat and including a grip for attachment by gripping of the seat on the rail, movable between a free position and an active attachment position of the seat, via a maneuvering lever movable between a free position and an active position for blocking in the active position of the grip. The system includes a lock for locking the lever in the active blocking position. The lock includes an axle that is rotatable relative to one of the lever and the base between an unlocked position and a locked position. The axle is provided with an indexing element provided to engage with a complementary portion of the other of the lever and the base in the locked position of the axle.

Seat fittings for attaching seats to seat tracks in a vehicle and related systems and methods are described herein. An example seat fitting includes a body having a bottom surface to face a seat track, a locking stud, and a solenoid disposed in the body. The solenoid is operable to move the locking stud between a retracted position in which the locking stud is disposed in the body and an extended position in which the locking stud extends outward from the bottom surface of the body and into the seat track.

A seat assembly that is attached to a floor of a vehicle. The seat assembly can include a seat with one or more flex beams that support the seat above the floor. The flex beams comprise a bowed shape with a curving intermediate section positioned between opposing ends. The flex beam is configured to compress when a force is applied to the seat assembly to absorb energy. The flex beam is also configured to impede the return of the flex beam to the first position after the force is removed.

An ottoman for an aircraft passenger seat is disclosed. In one or more embodiments, the ottoman may include a base. The ottoman may include a frame. The ottoman may include a shell. The ottoman may include a resting surface. The ottoman may include an actuation assembly. The actuation assembly is configured to actuating the resting surface from a first actuation position relative to the base. The ottoman may include an attachment surface. The attachment surface provides and anchor point for the actuation assembly.

A seat unibeam may include a defined cavity, a hole in an end of the seat unibeam, and an exterior surface. The defined cavity may be dimensioned to receive an electronics package inserted within the seat unibeam. The electronics package may include a plurality of electronics package sections. The hole may lead to the defined cavity. Each of the plurality of electronics package sections may be inserted into the cavity defined in the seat unibeam via the hole in the end of the seat unibeam. The exterior surface may be dimensioned to pass through at least one hole in a plurality of seat legs. The exterior surface may be dimensioned to pass through at least one hole in a plurality of spreaders including adjacent spreaders configured to support one or more components of an aircraft seat of the set of aircraft seats.

A rail system for a vehicle includes a floor rail integratable into or onto the floor, first elongate movement rail elements, second elongate movement rail elements, holding devices to hold the movement rail elements on the floor rail, and gliders supportable on the movement rail elements in a gliding manner. The movement rail elements have a rail profile cross-section perpendicular to their main extension axis; the cross-section has an undercut that faces laterally outwards. The movement rail elements each have two opposed end faces, which can be brought into contact with end faces of other movement rail elements, such that at least one continuous movement rail with a constant rail profile cross-section is created. The gliders include a recess corresponding to the rail profile cross-section for gliding support.

The invention relates to an aircraft passenger seat, comprising a frame intended to be fastened to a floor of an aircraft passenger cabin, a seat base movably mounted on the frame, and a movably mounted seat back. The aircraft passenger seat is characterized in that at least one rail is fastened to the frame and in that the seat base is slidably arranged on the rail by means of guide elements.

An aircraft seat fixation device for a fixation at least of a portion of an aircraft seat on at least one fixation rail that is fixated on an aircraft structure comprises a seat base structure which is configured such that at least the aircraft seat is mounted thereon at least partially, further comprises at least one seat foot which is connected to the seat base structure, and comprises at least one fitting element which is connected to the seat foot and is at least configured to be coupled with the fixation rail,

wherein the aircraft seat fixation device comprises at least one compensation unit, which is arranged on the seat base structure, the seat foot and/or the fitting element and which is configured to permit at least one compensation movement of the seat base structure at least in an overload case.

A floor structure for an aircraft includes a rail that defines a recess having an opening and a bottom and designed to receive one or more attachment elements, a covering element arranged above a segment of the recess so as to provide a complementary bearing surface above the opening, and a cellular supporting structure having a first end that rests on the bottom of the recess, and a second end supporting the covering element. Thus, the covering element can be sufficiently thin to avoid or limit the formation of steps at the surface of the floor structure.

A seat frame fastening assembly for laterally fastening a seat frame in a vehicle, wherein the seat frame fastening assembly comprises a holding rail arranged in a longitudinal direction of the vehicle, and a lateral element laterally fastened to a seat frame and coupled to the holding rail. The holding rail comprises a first power- and/or data-transfer interface and the lateral holding element comprises a second power- and/or data-transfer interface. The second power- and/or data-transfer interface is furthermore arranged in the lateral holding element such that a position of the second power- and/or data-transfer interface corresponds to a position of the first power- and/or data-transfer interface when the lateral holding element is coupled to the holding rail. Furthermore, a seat frame has such a seat frame fastening assembly, a vehicle portion has a corresponding seat frame and a vehicle has such a vehicle portion.
