Abstract: A passenger seating assembly with an integrated cabin attendant seat (CAS) is disclosed. In embodiments, a CAS folds down from a monument mounted to the cabin floor via a combined track fitting that secures into the left-side or right-side track rail. A group of passenger seats (e.g., two to five) faces opposite the CAS monument and includes left-side and right-side leg assemblies mountable to the track rails via track fittings. One rear portion of a leg assembly attaches to the combined track fitting to integrate the passenger seats and CAS monument, eliminating unused space between the passenger seats and CAS monument.

Abstract: 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.
