Abstract
The seats are swivellable about axes (1) and arranged with their axes in column axes (2). The seats each have a direction (4) extending from the middle of the seat back through the middle of the seat cushion (22), intersecting the seat's swivel axis. Extending equally on either side of the seat direction is defined a seat projection (5) forwards of the seat cushion and having the same width as the seat cushion. The swivel is set up to allow the seat to be turned through 6 from 17.5 to the longitudinal axis of the column (and the aircraft to be equipped with the seats) to 23.5. At 17.5, as in column IV, the seats partially face the seats in front in the column. This is the maximum angle at which the regulatory authorities will allow a lap belt only to be worn by a passenger for TTL. When the seats are swivelled outwards to 23.5, they face the space (6) along side the seat in front and can be converted to bed mode.
