PCT No. PCT/GB89/01060 Sec. 371 Date May 10, 1991 Sec. 102(e) Date May 10, 1991 PCT Filed Sep. 8, 1989 PCT Pub. No. WO90/02685 PCT Pub. Date Mar. 22, 1990.A main seat support frame includes slidable seat sections to allow the overall length of the seat and the number of sitting positions to be varied as required. The frame is provided with fixing positions for arm dividers which allow delimitation of a predetermined number of sitting positions when the seat is fully expanded corresponding to an economy class configuration and a fewer number of sitting positions of greater sitting width when the seat is contracted corresponding to a business class configuration. Since the width of the seat backs remains constant, bolsters may be attached to them when the seat is contracted for business class usage allowing for rapid conversion of the seating arrangement as between economy and business class usage. |
