Abstract: A seat for a vehicle includes a sitting portion, a movable back; and a first guide mechanism configured to move the back from a first edge of the sitting portion to an opposite second edge of the sitting portion. The back is assembled on the sitting portion by a movable element including a base configured to move between the first edge of the sitting portion and the opposite second edge, and a support assembled pivoting on the movable base. The movable base is in a form of a stirrup, a base of the stirrup extending from a first lateral edge to a second latent edge of the sitting portion. Each branch of the stirrup extends substantially parallel to the first lateral edge and is curved at a free end under the sitting portion.

Abstract: A convertible seat to accommodate an aircraft passenger. The seat includes a frame, a sitting portion borne by the frame, a back, and a jointed footrest along the transverse edge of the sitting portion. The seat can change from a so-called seated position in which the back forms an angle with the sitting portion and its base is close to the rear transverse edge of the sitting portion to a so-called lying-down position in which it has a more or less level surface intended to accommodate a passenger in the lying down position. The frame is a fixed frame. At most two of the elements of the whole constituted by the sitting portion, the back, and the footrest form the more or less level surface of the seat in lying-down position. At least one additional berth is provided to cooperate with the sitting portion and/or the back and/or the footrest to form the more or less level surface intended to accommodate a passenger in the lying-down position.

Abstract: An aircraft cabin that includes a main structure being the structure of the aircraft and enclosing the cabin; a bridge forming a flat surface on which the seats are secured; an aisle extending longitudinally in cabin and elevated with respect to bridge, and beds or cots accessed by said aisle and arranged above seats of bridge, transversally with respect to aisle and on both sides of such aisle.

Abstract: A process for adjusting the interior space of a vehicle and a seat for implementation of the process. The process makes it possible to adjust the interior space of a vehicle including seats each having a sitting portion and a back. The process includes, for at least one seat, moving the back of the seat from a first position in which a lower edge of the back is facing a first transverse edge of the sitting portion to a second position in which the lower edge of the back is facing a second transverse edge opposite the first transverse edge. A seat implements the process. Such a process and seat may find application to the interior layout of aircraft.

Abstract: Layout of the top part of an aircraft cabin This layout involves an aircraft cabin (4) that includes a main structure (18) being the structure of the aircraft and enclosing the cabin (4); a bridge (20) forming a flat surface on which the seats (12, 42) are secured; an aisle (32) extending longitudinally in cabin (4) and elevated with respect to bridge (20), and beds or cots (14) accessed by said aisle (32) and arranged above seats (12,42) of bridge (20), transversally with respect to aisle (32) and on both sides of such aisle.
