Provided are seat track fittings and methods for installing passenger seats in aircraft cabins using these seat track fittings such that the same seat can be installed on different types of seat tracks. A seat track fitting comprises a leg support, a pin, and a base interconnecting the leg support and pin. During installation of the seat track fitting, the pin is inserted into an attachment opening of the seat track. The attachment opening is selected based on the desired position of a seat. A removable fastener then protrudes through the base of the seat track fitting and is inserted into another attachment opening of the seat track. The seat is then attached to the seat track fitting by inserting the stud end of the seat into the leg support of the seat track fitting and fixing the stud end within the leg support.

The invention relates to a device for protecting a detachable equipment anchoring rail having adjustable dimensions, which is lockable, tamper-proof, reusable and consists of elements which are interconnected in such a way as to be secured and deployable and to provide, whatever the level of deployment thereof, all of the functions for protecting the rail against any type of aggression via a locking system.

A vehicle seat includes a seat with a seat pan and a backrest with a backrest bottom edge articulately being disposed adjacent to a seat pan rear edge. The seat pan and the backrest are positionable with respect to one another such that the seat is configurable into at least one of a taxi, takeoff and landing position, a napping position, and a sleeping position. A swivel is disposed beneath the seat. Base tracking also is disposed beneath the seat, permitting the seat to move in a lateral and a longitudinal direction. The seat also includes a first control to lock and unlock movement of the seat in lateral or longitudinal directions and a second control to lock and unlock the swivel. The swivel may be unlocked while movement of the seat in the lateral and the longitudinal direction is locked.

A fastening system for passenger seats in a vehicle cabin has two or more guide rails to be integrated into or onto a cabin floor, and a plurality of slides, to be brought into engagement with the guide rails and having a flange for connection to a passenger seat to retain the passenger seat on a guide rail. Each guide rail has a profile cross section, perpendicularly to a main axis of extent (x), having a base region, a supporting region and an undercut situated therebetween. Each slide has a cavity, of complementary design with the profile cross section, and a necked region, to be brought into engagement with the undercut, thus enabling the supporting region to be enclosed by the cavity of the slide. Each slide has a rotatably mounted roller projecting into the necked region and can be brought into surface contact with a guide rail surface.

Tubular bodies for use in frames for seats of vehicles such as aircraft are described. A tube can include a sidewall that has a variable thickness along the length of the tube. The variable thickness of the sidewalls can result in the tube having a variable inner diameter along the length of the tube. The tube may also include a variable outer diameter.

A seat support for use with a vehicle seat and adapted to engage a track provided on the floor of a vehicle, the track comprising two inwardly-directed lips on opposed sides of a slot, the lips providing first alternating protrusions and recesses along the length of the track, the protrusions being spaced apart by a spacing distance, the first and second protrusions defining shoulder surfaces on each side thereof, the seat support having an elongate main body and comprising: an interface portion which has a profile comprising second alternating protrusions and recesses, the protrusions being spaced apart by the same spacing distance; and a first bracing member provided at or near a forward end of the main body, and a second bracing member provided at or near a rear end of the main body; wherein: the seat support is configured such that the second protrusions may be aligned with the first recesses so that the interface portion may be placed within the slot in an engagement position, the seat support being moveable with respect to the slot, from the engagement position into a bracing position in which the first and second protrusions are substantially aligned, preventing the interface portion from being removed from the slot; one of the first bracing member and the second bracing member is a fixed bracing member, being fixed substantially fixed in place with respect to the main body of the seat support, so that in both the engagement position and the bracing position the first bracing member is received in one of the recesses of the track; the other one of the first bracing member and the second bracing member is a moveable bracing member, being movable with respect to the main body of the seat support, between a retracted position, in which, when the interface portion is placed within the slot, the movable bracing member is above the level of the track, and a locking position, in which, when the interface portion is placed within the slot, the moveable bracing member extends into the slot; and when the seat support is in the bracing position and the movable bracing member is in the locking position, the first and second bracing members are received in respective recesses of the track, the first bracing member is braced against a first pair of shoulders on the track that face towards the rear of the main body, and the second bracing member is braced against a second pair of shoulders on the track that face towards the front of the main body.

An anti-rattle system for a passenger seat includes a foot pad. The foot pad includes an upper surface, a lower surface, and a protrusion extending outward from the lower surface of the foot pad. A method of securing a passenger seat with the anti-rattle system includes providing a seat track defining a track channel. The method further includes securing a leg assembly of the passenger seat to the seat track by adjusting the anti-rattle device such that a forward stud of the leg assembly engages track lips within the channel and the foot pad of the anti-rattle device engages an upper surface of the seat track. Adjusting the anti-rattle device includes positioning the protrusion in a track opening forward of the forward stud.

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.

An electronic housing houses electronics for an aircraft. The electronic housing has an outer wall surrounding an electronic receiving compartment; and fasteners on one side of the outer wall on an outer side. The fasteners are configured to engage in a snap-fit connection to a predefined raceway configured for the attachment of a cover by a snap-fit connection.

A fastening system has a fastening element and at least one fastening device having a flanged housing, a closure element, a hollow-sphere element and a spherical insert. The hollow-sphere element pivots about a first pivoting axis relative to the flanged housing, while the spherical insert pivots about a second pivoting axis in the hollow-sphere element. First engagement means in an opening of the spherical insert are of complementary design to second engagement means of the fastening element. The first and second engagement means are designed such that, in a first rotational position, the fastening element can be inserted freely into the opening and, in a second rotational position, the first and second engagement means engage in one another.
