Passenger accommodations are easily and rapidly convertible from conventional seats to bunk beds and back. A support structure ( 9 ) supports a seat pad ( 13 ) and a seat pad extension ( 15 ) and also rotatably supports a seat back ( 5 ). The seat pad extension ( 15 ) and seat back ( 5 ) are partially supported by the support structure ( 9 ) of a row of seats ahead of the convertible seats when the convertible seats are converted to bunk beds. A third bunk bed ( 21,23 ) may be unfolded under the lower bunk bed formed by the seat pad ( 13, 15 ). |
