ABSTRACT:
In a passenger seat arrangement a passenger seat with backrest is arranged movably on a support structure including two side support bases and a mounting beam structure extending across the support bases and having spaced box frame members including T-shaped grooves, the seat is mounted on bearing structures disposed in the grooves of the box frame members thereby providing for the movability of the seat relative to an adjacent seat mounted on the same support structure for adjustability of the seat spacing without obstruction of the leg room underneath the seats.
