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 seating arrangement comprising:
- a first 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 foot area (41) situated in front of each seat in the bed configuration and in an extension of each bed plane,
- 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 a second similar block in front of said seats,
- each foot area (41) of the at least first and second seats (3) comprises a rest surface (42) substantially in a horizontal plane of the second block said foot areas (41) being vertically offset such that a first of the rest surfaces (42) is situated at a height of the bed plane (35) of the first seat, and a second of the rest surfaces is situated at a height of the bed plane (35) of the second seat, the height of the bed plane of the first seat and the height of the bed plane of the second seat being different,
- the rest surfaces (42) of the foot areas (41) of the at least first and second seats (3) 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 chair configuration, the seat cushion of the first and second seats are situated at the same height 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 blocks are installed in a cabin, from the bed plane of the other of said at least first and second seats.
7 more elements
A cabin (1), or a part of a cabin, for transporting passengers, comprising:
- at least one line of at least a first and second block (2),
- each block further comprising 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 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 first block being arranged behind the second block in a same orientation,
- wherein the blocks are 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 the first block (2), when in the bed configuration, the bed plane (35) of each seat (3) is extended by a foot area (41) situated in front of said seat, inside the second block, in a built-in space, termed a column, between seat backs (32) of the seats (3, 3′) of said second block,
- said foot areas each comprising a rest surface (42) substantially in a horizontal plane of the column at the height of each bed plane,
- wherein the bed planes (35) of the two adjacent seats (3) of the first block (2) are at different heights above a floor of the cabin (1) such that the rest surfaces (42) of the foot areas (41) of said two adjacent seats are at least partially superposed.
