Abstract: A recline mechanism is described. The recline mechanism provides for adjusting an angle of a seatback of a passenger seat. The recline mechanism prevents angular adjustments of the seatback when a cylinder and piston assembly is in a locked state and permits the angular adjustments when in an unlocked state. A solenoid is provided to lock and unlock a valve of the recline mechanism. The solenoid is engaged and disengaged in response to receiving electrical signals from a button. The button generates an electrical signal when the button is depressed and again when the button is released. The button includes an electromagnet or a piezoelectric for generating the electrical signals.

Abstract: The present disclosure provides an aircraft monument housing a crew quarters positionable in an aircraft cabin adjacent a longitudinal aisle, and a combination including a passenger suite and an aircraft monument housing a crew quarters. The aircraft monument includes a transverse wall forming part of the monument and separating interior space within the monument from the adjacent passenger suite. The interior space of the monument is divided by a shelf into upper and lower compartments and the crew quarters is positioned in the upper compartment for resting and sleeping use by the cabin crew. The lower compartment may be used by the cabin crew or for locating galley components. The transverse wall may be contoured such that the interior space and the passenger suite nest to maximize density. A footwell serving the passenger suite may be recessed into the transverse wall.

Abstract: An aircraft interior structure for an aircraft cabin may include a main body with a plurality of walls, where at least one wall of the plurality of walls may be shared with an adjacent passenger suite including an aircraft seat. The passenger suite may be installed at an angle relative to an aisle of the aircraft cabin. The aircraft interior structure may include a cavity defined within the main body. The cavity may be a trapezoidal shape defined at least in part by the angle at which the passenger suite is installed in the aircraft cabin. The cavity may be configured to receive a plurality of galley carts. A length of each of the plurality of galley carts may be dependent on a depth of the cavity at respective locations in the trapezoidal shape.
