Abstract
The present invention provides a seat for a passenger vehicle, particularly an aircraft, which seat comprises a first fixed part for supporting the seat adjacent a floor of a vehicle; a second movable part comprising a seat pan component, a back-rest component and a leg-rest component. A guiding device between the first fixed and second movable part for guiding movement of the movable parts relative to the fixed part between an upright position and a fully reclined position, such that as the movable part is moved towards the fully reclined position, said back-rest component is lowered translationally towards the floor. A reclining device for reclining the back-rest component from an upright orientation to a fully reclined orientation as the movable portion is moved from the upright to the fully reclined positions. A first pivot for allowing the leg-rest component to be pivoted relative to the seat pan component between a raised position and a lowered position; and second pivot for allowing the seat pan component to be pivoted relative to the back-rest component. A locking drive is associated with one of the first and second pivots for pivoting relative to each other the components pivoted on the one pivot, free pivoting is allowed of the components pivoted about the other pivot and a control is provided for controlling the operation of the locking drive. The arrangement being such that the locking drive is controlled such that the back-rest, seat pan and leg-rest components are oriented to define successive comfortable positions for a passenger, with the leg-rest remaining in contact with the floor.
