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.
