Abstract: Described is a seat track stud for attaching a passenger seat to a seat track having a first stud member, a second stud member, and a pin. The first stud member includes a base portion with at least one flanged edge, a first securing portion extending from the base portion and defining a first securing portion opening; and a second securing portion extending from the base portion at a location opposite the first securing portion and defining a second securing portion opening. The second stud member includes a connecting portion that defines a connecting portion opening and that is sized to fit between the first securing portion and the second securing portion. The pin extends through the first securing portion opening, the connecting portion opening, and the second securing portion opening.

Abstract: 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.

Abstract: A spring clutch arm assembly includes a moveable arm comprising a retracted configuration and a deployed configuration, a fixed shaft, and a spring portion comprising a moving portion with a distal end and a coil portion wrapped around the fixed shaft. The moveable arm may include a moveable member. The distal end may be attached to the moveable member. The moveable arm may be held in the deployed configuration by the spring portion.

Abstract: 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.

Abstract: Described are mounting assemblies for securing aircraft passenger seats, including a beam, an adaptor, and fasteners. The beam can include holes spaced along a flat upper surface. The adaptor can be supported by the beam and include a channel, a bottom thickness, and apertures extending through the bottom thickness. The fasteners can extend through the adaptor's apertures and the beam's holes to secure the adaptor to the beam. The adaptor can receive a fitting of a passenger seat in the channel to secure the passenger seat relative to the beam.

Abstract: A beam clamp (124) for a passenger seat includes a keyhole (126) configured to flex outwardly from an un-flexed position to a flexed position. The diameter of the keyhole in the un-flexed position is less than the diameter of the keyhole in the flexed position. A method of assembling the passenger seat includes assembling a seat base and connecting a seat back to the seat base. Assembling the seat base includes flexing the keyhole of the beam clamp outwards from the un-flexed position to the flexed position and inserting a support beam within the keyhole in the flexed position.

Abstract: Mounting techniques and systems are detailed. Such techniques and systems are particularly, although not necessarily exclusively, useful for connecting vehicle seat tracks to fixtures for dynamic testing. No holes need necessarily penetrate central portions of the base plates of the tracks.

Abstract: A track fitting assembly for removably securing a seat to a generally channel-shaped track secured to the fuselage of an aircraft. The track fitting assembly includes a forged body member having spaced track lugs projecting laterally from a narrow finger portion. The body member has a socket which receives a threaded shear plunger adjusting screw. A head on the adjusting screw moves into the socket to indicate when the shear plunger is properly seated to lock the track lugs in the track.

Abstract: A seat leg and track fitting assembly for removably securing a seat to a generally channel-shaped track secured to the fuselage of an aircraft. The track fitting assembly includes a forged body member having a narrow finger portion; a plurality of spaced track lugs projecting laterally from the narrow finger portion, and an enlarged boss portion having a recess formed therein. The recess extends through the narrow finger portion to form a pair of shoulders adjacent opposite sides of the recess and a plunger has surfaces positioned between the shoulders such that the shoulders limit movement of the plunger. An actuating arm is secured to the plungers in each of a plurality of track fitting assemblies to move the plungers in the recesses between first positions wherein the lower ends of the plungers are positioned adjacent the lower edge of the narrow finger portion of each body and an elevated position wherein the plungers are retracted from the track.
