Aircraft passenger seat assembly including backrest reclining device

Abstract

An aircraft passenger seat has a seat back including a lower portion pivotally mounted to a seat bottom and an upper portion rotatably coupled to the lower portion. During an articulated movement of the seat, the upper part may pivot forward relative to the lower part. An inner diaphragm may be positioned between the head restraint and a set of side frame members of the upper section and rotatably coupled to the upper and lower sections to provide support for the upper back and shoulders of a seated occupant. The actuation assembly provides coordinated articulation of the lower, upper, and inner diaphragms to allow the seat to articulate between an upright taxi takeoff and landing (TTOL) and reclined position and allow for more ergonomic seated occupants pose.

AI Technical Summary

Problems solved by technology

Actuators and associated components such as motors, circuitry, and cables add to the overall weight of an aircraft seat, which can limit the number of sleeper seats that can be added to an aircraft

Additionally, these traditional seats may rely on multiple articulating elements, such as the seat back, headrest, or legrest, for added passenger comfort, which can make it difficult to adjust and find a comfortable position

For example, in these conventional seats, each hinge element may have to be actuated individually and sequentially one by one
