A retrofit seat back assembly is disclosed. In various embodiments, the assembly includes a supplemental recline panel having an upper end and a lower end; a pivot member disposed proximate the upper end and configured to pivotally engage a seat back frame of a stowable seat; an actuator disposed proximate the lower end and configured to operably engage the seat back frame and move the supplemental recline panel between a retracted position and a deployed position; and a bias element disposed between the supplemental recline panel and the seat back frame and configured to urge the supplemental recline panel toward the seat back frame.

A passenger seat arrangement for installation in an aircraft comprises at least one seating unit comprising a backrest element and a seat element pivotable relative to the backrest element between a resting position and a position of use. The passenger seat arrangement also has a support frame which bears against the at least one seating unit and which is able to be connected in a load-bearing manner to a structure of the aircraft. The support frame has at least one mechanical interface which, in each case, is assigned to a seating unit and is designed to fasten different mutually exchangeable modular units in a releasable and load-transmitting manner to the support frame.

An interior configuration for an aircraft including a longitudinal aisle and rows of passenger seats, wherein a row of the passenger seats is disposed in a flexible use space adjacent the aisle and a bulkhead, and wherein the flexible use space includes a floor palette and attendant seats equipped with flip-up seat bottoms such that the flexible use space can be configured for passenger seating or to provide securement space within the flexible use space for securing items such as a wheelchair, pet carrier, large items and items of value.

An example seat pan for an aircraft includes a first portion having a first end and a second portion that is adjacent to the first portion and is adjustable to be in a first position in which the second portion forms a seating surface together with the first portion, the seating surface having a width that is wider than a width of the first end of the first portion. The second portion is adjustable to alternatively be in a second position in which the first end of the first portion extends beyond the second portion to be insertable into a footwell.

A bulkhead-mounted aircraft seat assembly configured for independent vertical and horizontal adjustment includes an aircraft seat (seatback and seat frame/cushion) for supporting a pilot, passenger, or other occupant. Parallel rails attach to the bulkhead and extend along the bulkhead (vertically or near vertically) with opposing slots set into each rail. A sled translates along the rails via paired sliding members set into the slots, each pair of sliding members connected to an axle extending through the sled. A four-bar linkage attached to the sled and to the aircraft seat; the four-bar linkage extends from a default position to allow the aircraft seat to translate along a horizontal linear rail under the seat while maintaining a stable vertical reference point above the cabin floor. The seat is independently configured for substantially vertical adjustment via a metering plate attached to the bulkhead.

A seat base assembly for an aircraft seat includes parallel rails attached to an aircraft bulkhead, each rail including a slot extending vertically within the rail. The seat (e.g., seatback and seat frame) is attached to a sled capable of vertical translation relative to the bulkhead via slidable members that translate along the slots. The sled includes a hole for accommodating a locking pin controllable by the seat occupant. A metering plate attached to the seat base behind the sled is folded over a lateral axis into a forward and rear layer, the forward layer including holes for the locking pin wherein each hole corresponds to a desired seat height to which the seat may be adjusted by securing the locking pin through the sled hole and metering hole. In response to an impact event, the metering plate deforms to absorb impact energy and control downward deceleration of the seat.

A cabin attendant seat includes a housing having an upper portion and a lower portion, a headrest rotatably coupled to the upper portion, a seat pan coupled to the lower portion, and a drop-down tray assembly rotatably coupled to the upper portion. The seat pan is detached from the headrest. The drop-down tray assembly and the headrest are configured to rotate along a first axis such that the drop-down tray assembly defines a platform.
