Abstract: An anti-rattle track fastener assembly for attaching a fixture to a vehicle that has a track formed therein. The track includes upper walls that form a longitudinally-extending slot. Spaced-apart segments extend from the upper walls into the slot to provide undercut areas in the slot positioned under the segments. Spaced-apart openings are positioned between the segments. The fastener assembly includes a stud that extends from the fixture and is dimensioned to be received within the slot for engaging the spaced-apart segments. The fastener also includes an eccentrically-mounted cam movable between a first position and a second position. When the cam is in the first position, the stud can engage the spaced-apart segments with clearance, and when the cam is in the second position, the stud can tightly engage the spaced-apart segments.

Abstract: A passenger seat includes a rigid frame, a seat pan supported by the frame and movable relative to the frame, a leg rest pivotally attached to a forward end of the seat pan, a seat back pivotally attached to a rearward end of the seat pan, and a single actuator linked to the leg rest such that extension of the actuator causes the leg rest to pivot forward, the seat pan to move forward, and the seat back to recline. A method of adjusting the passenger seat includes activating the actuator such that extension of the actuator causes the leg rest to pivot forward, the seat pan to move forward, and the seat back to recline.

Abstract: An aircraft passenger seat that includes a frame with a seat bottom mounted for translating fore and aft movement, and a seat back linked to the seat bottom and mounted for generally vertical movement between a lowered and upright position. A stationary seat back shell assembly is provided within which the seat back is mounted for movement. A seat back position indicator is carried by the shell proximate a top end thereof and cooperates with the seat back. The seat back position indicator has a first condition indicating that the seat back is in the lowered position within the shell and a second condition indicating that the seat back is in the upright position within the shell.

Abstract: A passenger seat for a vehicle having a floor includes a footrest positioned forward of a seat bottom. The footrest includes a resilient support surface positioned above the floor for supporting a passenger's feet. The footrest may be an enclosure suspended below the bottom of a forward-positioned seat. In an alternative embodiment, the footrest may include a resilient support surface footrest which allows each of a passenger's feet to be supported above the floor in different longitudinal positions.

Abstract: A passenger seat for a vehicle is mounted by an extendible stud assembly which includes a housing attached to the seat; and a movable plunger carried by the housing and including a locking stud adapted for engaging a locking track. The housing is constructed such that movement of the stud relative to the housing under an applied load causes deformation of the housing which resists the motion. This controlled motion of the locking stud allows a deck of the aircraft to deform under crash loads without imposing excessive loads on the passenger seat.

Abstract: A passenger seat includes a frame, a bottom, a back, and a headrest, and incorporates a cylindrical motion support member. The support member includes a stationary member carried by the passenger seat, including a concave surface having a cylindrical curvature. A moveable member has a convex surface with a cylindrical curvature disposed in contact with the concave surface, and a support surface for supporting at least a part of a passenger's body The moveable member is selectively positionable along the concave surface. In another variation, the seat back and/or seat bottom is moveable in a conical motion.

Abstract: A locking apparatus for a moveable component of an aircraft seat. The locking apparatus includes a housing for being slidably received in a track, a first pair of opposed cams pivotally mounted in the housing, and a release member. The cams are moved between a lock position where the cams prevent the housing from sliding within the track and a release position. The release member is selectively moveable between a first position where the cams are maintained in the lock position and a second position where the cams are maintained in the release position.

Abstract: A frame assembly for vehicle passenger seat, including at least one leg unit, including a cantilevered transverse main beam carried by a fore and aft-extending seat leg for being mounted to the floor of the vehicle, a transversely extending front beam positioned forward of the seat leg, a backshell attached to and carried by the transverse main beam, a seat back carried on the backshell, and a seat bottom carried by a perimeter frame mounted on the backshell.

Abstract: A passenger seat for a vehicle, including a frame for being attached to a floor of the vehicle, a fixed backshell attached to the frame, and a seat back attached to the backshell. A seat bottom is attached to the backshell, and a headrest assembly attached to the backshell at a position above the seat back. The headrest assembly includes left and right spaced-apart side wings, each of the side wings comprising a rigid support and a wedge-shaped cushion attached to the rigid support by a pivot. The left and right cushions are each translatable in a direction parallel to the rigid support to selectively increase or decrease the effective width of the headrest assembly by increasing or decreasing the distance between the left and right side wings. The left and right cushions are each mounted for rotation about the pivot for selectively changing the angle of a forward face of the cushion relative to the rigid support to thereby permit selection by a seat occupant of a desired cushion position.

Abstract: A passenger seat for a vehicle includes a seat back; and a seat bottom. The seat bottom is selectively moveable between a first, generally flat position for supporting a passenger in an upright seating position with the passenger's hips located at a first height above the floor, and a second, raised position for supporting a passenger in a semi-standing position wherein the passenger's hips are positioned at a second height above the floor substantially greater than the first height.

Abstract: A tilting seat bottom assembly for a passenger seat includes: a seat pan assembly for supporting a passenger and a pivot assembly for being attached to the seat frame. The seat pan assembly is mounted for pivotal motion about at least two axes relative to the seat frame, and can be locked in a selected orientation by the passenger.

Abstract: A passenger seat for a vehicle includes a seat back; and a seat bottom, which may be mounted to a fixed backshell. The seat bottom is selectively configurable such that at least a portion of one side thereof is higher than at least a portion of the opposite side thereof, relative to a floor of said vehicle, so as to support a passenger who is seated on said seat bottom in a rotated position wherein one of said passenger's hips is higher than the other hip relative to said floor.

Abstract: A track fastener assembly for securing a seat or cargo apparatus to a floor track of a vehicle. The assembly includes a bottom rail with forward and aft ends. Front and rear movable slides carrying locking studs are carried by the bottom rail. A locking rod having a helical groove formed in its outer surface is operatively connected to the bottom rail and the slides. Rotation of the locking rod causes the slides to move axially from an installation position to a locking position. As the slides move to the locking position, they are deflected upwards along with the attached locking studs, clamping the track fastener assembly to the track.
