The control panel may be embedded in one of the surfaces of a tray table and may control at least one piece of cabin equipment associated with a passenger seat having the tray table. The table support may be connected between opposing sides of a tray table to pivotably support the tray table on a seat back of a passenger seat having the tray table.

Abstract: Described is an adjustable friction slider assembly having a rail member and a carriage assembly moveably coupled to the rail member, the carriage assembly having a bracket member and a plurality of roller elements moveably coupled to the rail member and coupled to the bracket member using a plurality of attachment members, the plurality of roller elements comprising at least one adjustable roller element coupled to the bracket member using a moveable attachment member, wherein moving the moveable attachment member adjusts a friction between the plurality of roller elements and the rail member.

Abstract: Described are tray table assemblies for a passenger seat, such as an aircraft passenger seat. The tray table assembly includes a tray table with a top surface and a holder assembly. The holder assembly includes a first holder pivotably attached to the tray table and a second holder pivotably attached to the first holder.

Abstract: Described are aircraft seat frame assemblies comprising a tube and a seat frame component mounting system. The seat frame component mounting system comprises a first tube mounting member and a second tube mounting member separable from the first tube mounting member. The tube is positionable between the first tube mounting member and the second tube mounting member. The seat frame component mounting system further comprises a fastener extending at least partially through the second tube mounting member, the tube, and the first tube mounting member to couple the second tube mounting member to the first tube mounting member. A clamping force is substantially evenly applied from the second tube mounting member and the first tube mounting member against an outer circumferential surface of the tube via the fastener.

Abstract: A passenger seat includes a spreader with one or more open slot. The slot may be positioned on a lateral side of the spreader and may receive a portion of a seat base of the passenger seat within the slot. In some aspects, the slot may be elongated, and an insertion opening for the slot is provided in a top side of the spreader.

Abstract: Described is a passenger seat assembly that may include a seat back including a rearward surface, a seat shroud positioned proximate to the rearward surface of the seat back and fixedly coupled to a seat frame, wherein the seat shroud remains stationary as the seat back moves between a stowed position and a deployed position, and at least one moveable shroud member coupled to the seat shroud at an attachment point and positioned proximate a rearward surface of the seat shroud, wherein a location of the attachment point is adjustable.

Abstract: Described are seat backs for passenger seats. The seat back includes a frame, and the frame includes an upper portion and a lower portion. The upper portion includes a top end of the seat back, and the lower portion is adjacent to the upper portion. A thickness of the upper portion of the frame may be less than a thickness of the lower portion of the frame.

Abstract: Described are base frame assemblies for a passenger seat having an elongated tube and a connector. The elongated tube may include an inner surface, an outer surface, and a connecting aperture extending from the inner surface to the outer surface. The connector may include a first end, a second end, a central opening extending from the first end to the second end, a first stopper at the first end, a second stopper proximate to the second end, a contact surface between the first stopper and the second stopper, and an adjustment slot defined as extending from the first end to the second end.

Abstract: Described are passenger seat reclining systems having a seat pan; a seat back fixed with respect to the seat pan; and at least one spreader. Motion track segments of the spreader may cause a particular recline motion. For example, the motion track segments may cause the seat body to rotate about an axis adjacent to the headrest during transition from an upright position to a reclined position of the passenger seat. Additionally or alternatively, the motion track segments may be configured such that the seat pan translates down and forward when the passenger seat transitions from an upright position to a reclined position, and such that the seat back is constrained to undergo less than less than 3 inches (7.62 cm) of rearward translation in recline travel when the passenger seat transitions from the upright position to the reclined position.
