An armrest assembly for a passenger seat may include an armrest and an attendant step assembly. The armrest may include a top side and a bottom side, and the attendant step assembly may be connected to the bottom of the armrest. The attendant step assembly is movable between a stowed position and a deployed position relative to the bottom side of the armrest.

A structural shroud for a passenger seat assembly includes a hollow body having a first end, a second end opposite from the first end, and a central cavity between the first end and the second end. In certain embodiments, the structural shroud may include a magnesium alloy and/or an aluminum alloy, and may be formed via casting, forging, and/or additive manufacturing, among others. In some embodiments, a base frame assembly for a passenger seat assembly includes a monolithic base frame having a first leg portion and a first tube portion integrally formed with the first leg portion.

An adjustable armrest assembly provides for quick and easy height and tilt adjustments to the armrest. Generally, the armrest assembly disclosed herein includes a base, an armrest, and one or more shafts extending from the base and being pivotably coupled to the armrest. By moving the one or more shafts relative to the base, the height and/or tilt of the armrest relative to the base can be adjusted.

Disclosed is a pilot aircraft system control input arrangement for a light aircraft having primary flight controls, the pilot aircraft system control input arrangement integrated into an armrest for a pilot's seat, the armrest providing forearm support for a pilot and having integrated therein or associated therewith a primary flight control and wherein the pilot aircraft system control input arrangement is disposed to be reached by fingers of a pilot with their forearm resting on the armrest, the pilot system control input arrangement comprising: a numerical keypad interface for inputting data; a rotatable selector for inputting data; a function selector operable to switch the pilot input arrangement between at least two input functions that each enable the pilot input arrangement to receive a different type of input, wherein the types of input for the at least two input functions are selected from at least two of the following input categories: a pressure setting for an altimeter; a transponder code for a transponder; a frequency for radio or navigation equipment; a course or heading for an autopilot or navigation equipment; an interfacing arrangement for communicating inputs to at least two aircraft systems selected from: an altimeter; a transponder; a radio; a navigation system; and an autopilot system.

An arm rest assembly and aircraft passenger seat including the same. The arm rest includes a friction mechanism for resisting abrupt rotational movements of the arm rest. A rotationally fixed frame member defining a rotational axis and receives a rotational member of the arm rest configured to rotate around the rotational axis. A groove formed in an outer circumferential surface of the rotational member seats a O-ring disposed between the groove and an inner circumferential surface of the frame member. Tolerance between the frame member and arm rest is such that the O-ring is held in the groove in a compressed state and frictionally engagement each of the rotational member and the frame member.

A passenger seat for an aircraft is described. The passenger seat is configurable between an upright position and a bed position. The upright position may be provided for taxi, take-off and landing events. The bed position, also referred to as a lie-flat position, is provided for long-haul travel in comfort. The passenger seat includes a seat pan, a seatback, and an armrest. The seat pan, the seatback, and the armrest form a kinematic chain by a number of pivot joints. The passenger seat also includes a linkage connecting the seat pan and the armrest. By the linkage, the armrest follows a motion of the seat pan when the passenger seat is reconfigured.

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.

An aircraft armrest lifting mechanism generally biases the aircraft armrest toward a raised configuration. A linear actuator applies tension to a cable connected to a portion of an armrest hub connected to an armrest shaft. The portion of the armrest hub extends some distance from the armrest shaft so that the linear actuator applies a moment between an attachment point on the armrest and the armrest shaft that tends to rotate the armrest toward a raised configuration.

An adjustable armrest assembly provides for quick and easy height and tilt adjustments to the armrest. Generally, the armrest assembly disclosed herein includes a base, an armrest, and one or more shafts extending from the base and being pivotably coupled to the armrest. By moving the one or more shafts relative to the base, the height and/or tilt of the armrest relative to the base can be adjusted.

The present disclosure provides a deployable and height adjustable armrest assembly for use with, for example, an aircraft pilot seat. The assembly includes an armrest positioned atop a rack comprising a plurality of detents each corresponding to a deployed armrest position. A lever carries a pawl that travels along one edge of the rack which locates in a selected one of the plurality of detents to lock the armrest in one of its deployed positions. The armrest is configured to be raised manually to deploy and adjust the armrest upward. The lever is configured to be actuated manually to disengage the pawl from its engagement in one of the detents to lower or return the armrest to its stowed positions. The armrest is particularly advantageous in close quarters such as a flight deck, or where a stowed armrest can be used to expand the width of the seat bottom.
