A system may include a seat assembly. The seat assembly may include a seat base, a seat portion mounted to the seat base, and an armrest assembly configured to be in an up position or a down position. The armrest assembly may include a handle operable by a user to lock or unlock at least one functionality of at least one adjustable seat assembly feature. Operation of the handle may be configured at least to: unlock the at least one functionality of at least one adjustable seat assembly feature while locking the armrest assembly from moving between the up position and the down position.

Disclosed is an armrest assembly for a vehicle seat such as a pilot seat positioned in an aircraft cockpit. The armrest assembly generally includes a pivoting armrest and an arm pad repositionable relative to the armrest to change the arm pad width. The arm pad includes two functional sides each having a different width dimension. The arm pad is coupled to the armrest such that sequential translational and rotational motion of the arm pad moves one of the first and second sides into a use position atop the armrest and the other of the first and second sides into an out of use position alongside the armrest. The armrest assembly according to the present disclosure is ideal for use in tight quarters within the flight deck, among other installation environments requiring a functional armrest.

The present invention provides an aircraft cabin comprising an aisle defining an aisle axis, a plurality of aircraft passenger seats arranged in a seat column adjacent the aisle, and accessible from the aisle, each aircraft passenger seat comprising a seat pan and a backrest with a front face defining a seat facing direction and a rear face, and each aircraft passenger seat being convertible between a seat configuration and a bed configuration, wherein each aircraft passenger seat in the seat column is able to be angled away from the aisle such that the seat facing direction is at an angle of at least degrees from the aisle axis and wherein each aircraft passenger seat can be in the bed configuration when at that angle. The invention also provides an aircraft passenger accommodation unit, an aircraft, a kit of parts and a method of providing enhanced passenger access to an aircraft passenger accommodation unit.

An aircraft seat (1) is disclosed. The aircraft seat (1) comprises a seating surface (51), an armrest (7), and a gas strut (9) configured such that the armrest (7) can be moved between a raised position a lowered position in which an armrest surface (71) is substantially level with the seating surface (51). The gas strut (9) comprises a switch (92) with an unlocked configuration in which the stroke of the gas strut (9) can be adjusted and a locked configuration for locking the stroke of the gas strut (9) so that the armrest (7) can be held at any position between the raised position and the lowered position. A trigger (117) is configured to move the switch (92) between the locked and unlocked configurations upon actuation of an actuatable member (111) that is located upon a surface of the aircraft seat (1).

A step assembly installable in a structure such as a housing of an armrest assembly, the step assembly including a base attachable to the structure including a mounting plate having a low profile and a fixed receptacle to be received in the structure, a step plate pivotally attached along a first end to the base along a lower end of the receptacle, the step plate pivotable between a stowed position in which the step plate is housed within the fixed receptacle and a deployed position in which the step plate is outside of the fixed receptacle, the step plate having a first side for supporting a foot, and a release mechanism for releasing the step plate from the stowed position to the deployed position. The step plate deployed for use and concealed from view between uses.

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.

A low profile armrest articulation mechanism for a passenger seat is disclosed. The passenger seat has a seatback reclinable from an upright configuration to a berthed or horizontal configuration (e.g., parallel to the seatpan). The mechanism includes moving stops connecting the armrests on either side to the seatback and linkages connecting the moving stops to the seat frame. As the seatback reclines, the moving stops maintain the armrests at an optimally ergonomic angle (e.g., substantially parallel to the seatpan) for as long as possible. When the seatback reaches the fully reclined or berthed configuration, the armrests may be pivoted upward into a berthed orientation flush with the seatback, adding bed space to the berthed configuration.

An aircraft seat system is disclosed, in accordance with one or more embodiments of the present disclosure. In one embodiment, the aircraft seat system includes a seat casement; a headrest portion; a seat back portion; a seat pan; and one or more armrests pivotably coupled to one or more portions of the seat casement. In another embodiment, the one or more armrests include an armrest body; a rotator link system; and a pivot link system. In another embodiment, the pivot link system may be configured to pivotably extend the armrest cap and pivotably retract the armrest cap.

An armrest may comprise a first casing and a second casing coupled to the first casing. An angular armrest adjustment assembly may be located between the first casing and the second casing. The angular armrest adjustment assembly may comprise a hub coupled the first casing, a lever ring configured to engage a splined surface of the hub, and a biasing member configured to bias the second casing away from the lever ring.

An armrest is disclosed that includes an armrest frame rotationally coupled to a seat frame, an armrest subframe pivotably couple to a second end of the armrest frame, and an arm pad laterally aligned and translatably coupled to the armrest subframe. The armrest further includes a tilting mechanism configured to pivot the armrest subframe relative to the armrest frame. The armrest further includes a translation mechanism configured to translate the arm pad relative to the armrest subframe. The armrest further includes a rotation mechanism configured to rotate the armrest relative to the seat frame. At least one of the tilting mechanism, the translation mechanism, or the rotation mechanism includes a spring-loaded linkage.
