Cabin seat for aircraft

The seat has a frame, and a wheel cooperating with a floor of a cabin for moving the seat. An actuator rotates the wheel around an axis and has a drive shaft (22). A motor rotates an upstream shaft around the axis with respect to the frame, and a brake blocks the rotation of the upstream shaft around the axis. A reduction chain (50) mechanically connects the upstream shaft and the drive shaft. The chain comprises gear elements (150) arranged coaxial to the drive shaft. The chain comprises a set of satellites (154, 156) cooperating with the gear elements.
