Abstract: Seating assemblies, principally for passenger vehicles such as aircraft, are detailed. Memory devices associated with the seats may receive information in the form of seat-adjustment preferences for the passengers to whom the seats are assigned for a journey. The information may be provided directly by a passenger while on-board the vehicle or in advance of the journey. Crew overrides of the adjustment preferences may occur. The seats additionally may include alarms or provide other functionality of interest to passengers and authorities.
