US Patent 12024296 Passenger seat with non-intrusive recline

Described are passenger seat reclining systems having a seat pan; a seat back fixed with respect to the seat pan; and at least one spreader. Motion track segments of the spreader may cause a particular recline motion. For example, the motion track segments may cause the seat body to rotate about an axis adjacent to the headrest during transition from an upright position to a reclined position of the passenger seat. Additionally or alternatively, the motion track segments may be configured such that the seat pan translates down and forward when the passenger seat transitions from an upright position to a reclined position, and such that the seat back is constrained to undergo less than less than 3 inches (7.62 cm) of rearward translation in recline travel when the passenger seat transitions from the upright position to the reclined position.
