ABSTRACT:
A seat usable in an airplane, train, or bus has a generally horizontal seat part having an upper surface and a rear edge and an upright back part extending upwardly from this rear edge and having a lower edge at the rear edge. A pivot is provided between the back part and the seat part and defines a horizontal pivot axis generally parallel to the edges but substantially above the upper surface of the seat part. In addition this axis is at least as high as the level of the knees of a person sitting behind the seat in another such seat mounted on the same floor level. It is possible to lock the back part relative to the seat part in any of a plurality of anuglarly offset positions.
