  • Readily convertible aircraft passenger seats
    Patent number: 5104065
    Abstract: Two seat assemblies are provided side-by-side, in a row, on opposite sides of an aisle (16). A first seat assembly comprises window, middle and aisle seats (RW, RM, RA) which are movable between a first narrow seat spacing and a second wider seat spacing (FIGS. 7 and 8). The second seat assembly is convertible between three seats (LA, LM, LW) with the first spacing and two seats with the larger spacing (FIGS. 7 and 8). Each seat assembly includes a tube-in-tube support frame for the seats which allows the conversion and seat size to be accomplished by a simple sliding of movement of the aisle and middle seat frames towards and away from the window seat frame which is fixed in position (FIGS. 9 and 10).
