Abstract
A block of two seats side by side which can be converted individually between a chair configuration and a horizontal flat bed configuration, the longitudinal axes of two of the seats in the bed configuration converging towards a point situated in front of the seats at a distance such that the foot areas in front of the seats in the bed configuration are superposed. Bed planes of the two seats of the block are vertically offset and extended by rest surfaces of the foot areas arranged in a column arranged between the seat backs of the seats of a block situated in front, making it possible to reduce the seat pitch while not affecting comfort, and allowing an improved cabin layout for transporting passengers.
Claims19
A block (2), comprising:
- a first seat;
- and
- a second seat adjoining said first seat, said first and second adjoining seats (3) each including elements that include a seat cushion (31) and a seat back (32), and each seat being convertible, individually, by a relative movement of said elements including the seat cushion (31) and the seat back (32) between i) a chair configuration in which an occupant of the seat is in a seated position, and ii) a bed configuration in which the elements of the seat form a bed plane (35) and in which an occupant of the seat is stretched out substantially flat and substantially horizontally,
- the first and second seats (3) being arranged side by side and oriented substantially in a same direction, wherein,
- each of the at least first and second seats (3) is associated with a space situated in front of said seat in the bed configuration and in an extension of the bed plane, a so-called foot area (41), a longitudinal axis (34) of each of the at least first and second seats (3) in the bed configuration converges towards a convergence point situated in a vertical plane of symmetry of another block in front of said seats such that adjacent the foot areas (41), a leg rest portion of said at least first and second seats of the block are at least partially superposed, one over the other, in a vertical projection, and
- when the at least first and second seats (3) are both in the bed configuration, the bed plane (35) of one of said at least first and second seats is situated at a different height, relative to a reference surface corresponding to a cabin floor when said block is installed in a cabin, from the bed plane of the other of said at least first and second seats.
A cabin (1), or a part of a cabin, for transporting passengers, comprising:
- at least one line of at least two blocks (2) of at least first and second seats (3, 3′),
- wherein, in each of said blocks, each seat (3) of a block (2) is convertible individually, by a relative movement of elements (31, 32, 33) of the seat, between a chair configuration in which an occupant of the seat is in a seated position and a bed configuration in which the elements of the seat form a bed plane and in which an occupant of the seat is stretched out substantially flat and substantially horizontally,
- wherein, for each of said blocks, the seats (3, 3′) are arranged side by side and oriented substantially in a same direction, said at least two blocks being arranged one behind the other in a same orientation and separated, in a direction of the line of blocks, by a pitch X characterizing the distance between a reference point of each of the blocks (2),
- wherein, for each of the seats (3, 3′) of a block (2), following another preceding block, in the bed configuration a bed plane (35) of each seat (3) is extended by a foot area (41) situated in front of said seat, inside the preceding block, in a built-in space, termed a column, between seat backs (32) of the seats (3, 3′) of said preceding block, and in that the bed planes (35) of the two adjacent seats (3) of the block (2), both of said two adjacent seats (3) of the block (2) being in the bed configuration, are at different heights above a floor of the cabin (1) such that adjacent the foot areas (41), a leg rest portion of said two adjacent seats of the block (2) being superposed, one over the other, outside said column.
