Abstract
A reclinable passenger seat includes a seat pan linear actuator having a rear end pivotally connected to the rear end of the seat pan frame, and a front end pivotally connected to the base by a third fixed pivot. A backrest linear actuator has an upper end pivotally connected to the upper backrest member, and a lower end pivotally connected to the base. A length of the backrest linear actuator is defined between the upper and lower ends. The backrest frame and seat pan frame are configured to move simultaneously between at least a reclined configuration and a berth configuration through pivoting motion about the first and second fixed pivots and about the first and second locations. The length of the backrest linear actuator is substantially the same in the reclined configuration and in the berth configuration.
