Abstract: Vehicle seats are commonly used to transport passengers travelling on different classes of fare, for which seats of different width are often provided. Seats of different width are also desirable to accommodate passengers of different sizes. Adjustable seating units are known which include backrest and bottom parts for a plurality of seats abreast, fixed armrests at the sides and intermediate armrests which can be moved laterally between two or more predetermined positions to separate and define seats of different widths. To improve the appearance and comfort provided by such adjustable seating units, a shroud is provided to fit on or over two intermediate armrests when they are positioned close together between wider seats, the shroud being anchored to the seating unit, for example being mounted on arms pivotally connected to the seating unit, so as to be movable between an operative position, fitting the intermediate armrests, and a stored position.

Abstract: An adjustable seating unit, particularly for aircraft, comprises a backrest part and a bottom part capable of accommodating either three narrower seats or two wider seats, with intermediate armrests which are movable laterally between positions defining respectively the three narrower seats and the two wider seats. The intermediate armrests are anchored to the seating unit by linkages and complementary components are provided on the intermediate armrests and on the seating unit for selective engagement to locate the intermediate armrests positively in their respective positions.
