Abstract
The seat pan of an aircraft passenger sleeper seat is mounted on a pivot axle for movement between a normal substantially horizontal position and a tilted position in which its front edge is lower than its rear edge. The seat back comprises a first portion which is mounted for angular movement between a substantially upright position and a reclined position, and a second portion mounted on a pivot axle for movement between an erect position in which it is substantially parallel to the first portion and a reclined position in which its upper edge is lower than when in its erect position. When the seat pan is tilted and the second portion of the seat back is reclined, their upper surfaces form a substantially plane support surface for a sleeping passenger.
