Abstract
A seating unit for a passenger vehicle, especially an aircraft, has a reclinable seat back connected to a seating portion by a hinge. A slider is mounted in a guide track and supports the hinge. A pivotally connected front strut supports the seating portion at a location in front of the hinge. A pivotally connected rear strut supports the seat back at a location spaced apart from the hinge. As the slider along the guide track, the seat back moves to an orientation substantially coplanar with the seating portion so as to provide a flat surface for a sleeping passenger.
