Abstract: A passenger lift assembly includes a spine defining a motion path, a lift mechanism attached to the spine and configured to travel along the motion path, and a plurality of branch subassemblies attached to the spine, each branch subassembly including at least one leg configured to engage an upstanding wall of a seat shell positioned in relation to a passenger seat. In use, the passenger lift assembly mounts to a seat shell positioned in relation to a seat to facilitate transfer of a passenger from the wheelchair to a seat, and collapses for compact stowing between uses. The passenger lift assembly is particularly well suited for use with seats surrounded by upstanding walls and curved pathways extending from an aisle to a passenger seat.

Abstract: A method for changing passenger seating angle according to an aircraft flight mode utilizing a raked passenger seat configuration in which the seat angle relative to an aircraft longitudinal axis increases as the passenger seat transitions from an upright condition to a reclined condition. Such a passenger seat may be utilized in an aircraft passenger seating arrangement to maximize seating density while complying with defined taxi, takeoff and landing (TTOL) certification criteria for oblique seats, among other applications and benefits.
