ABSTRACT:
Convertible aircraft passenger seat can be quickly changed from a three-seating position configuration to a more spacious two-seating position configuration without the use of tools. Such a seat permits the seating capacity of an aircraft to be altered to match the expected passenger load in different classes, such as tourist and business class. In the three-position configuration, a pair of relatively narrow width armrests, which may contain recline lock control cables or audio cables, project vertically out of the lower seat cushion on either side of the center seating position but are pivotally mounted so that they will overlie the center position in a generally horizontal fashion in the two-position configuration, thus adding several inches of width to the adjacent end seating positions. Each of a pair of elongated back cushion side extensions has fastening means on one side thereof by which it may be alternatively attached to one side of a relatively narrow center position back cushion in the three-position configuration or to an inboard side of one of the end position back cushions in the two-position configuration. In the latter configuration, the relatively narrow center back cushion is folded forward where it conceals the laterally folded narrow armrests and forms a wide armrest and/or cocktail table between the two wide seats.
