Aircraft passenger seat assembly including a backrest tilt apparatus

Abstract

An aircraft passenger seat has a seat back including a lower portion pivotably mounted to a seat bottom and an upper portion rotatably coupled to the lower portion. The upper portion may rotate in a forward direction relative to the lower portion during articulation of the seat. An inner diaphragm may be positioned between a headrest and a set of side frame members of the upper portion and is rotatably coupled to the upper portion and lower portion to provide support for an upper back and shoulders of a seated passenger. An actuating assembly may coordinate articulation of the lower portion, the upper portion, and the inner diaphragm to permit articulation of the seat between an upright taxi takeoff and landing (TTOL) position and a reclined position and to enable the seated passenger to achieve more ergonomic postures.

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
