Seats (11) face in alternate directions in their rows. They have cushions (12), backrests (13), arm rests (14). The shoulder widths (16) of these seats are conventional. However, the conventional seats have their shoulder width extending to the centre of the arm rests of their seats. In other words, the arms rests are at the seat lateral pitch (5). In Figure 3, the shoulder width extends to the full width of the arm rests. In other words, the arm rests are set in and are arrange at a reduced pitch (15), which is the seat lateral pitch. This is of no inconvenience to the passengers, in that the latter are widest at their shoulders and there is room for their hips between the set in arm rests. The rows are set at a longitudinal pitch (17), shown as the distance between central axes of interdigitated parts of the seat cushions. The seat backs are set on two lines (19), parallel with but spaced from the axes (18). |
