Patent ID: 8882034

Claim:
A cabin set of aircraft seats arrangeable in four columns in the cabin, two against a central divider and two against cabin walls, the seats being of the type which are convertible between a sitting mode and a bed mode, wherein: each seat has: a movable seat cushion, a foot rest support fixed in use adjacent to the central divider or one of the cabin walls, a movable back-rest, the cushion and back-rest being movable from the sitting mode to the bed mode to form a bed upon extension of a leg rest that is supported by the foot rest support in use, a seat direction in which the seat faces and which is defined by a seat axis extending from the middle of the back-rest through the middle of the seat cushion and a seat projection area extending equally on either side of the seat axis forwards of the seat cushion and having the same width as the seat cushion, wherein: each seat includes a swivel on which the seat is mounted for changing the seat's direction in the column, each swivel has a swivel axis, the swivel axes of the seats of each of the four columns defining an axis of the column that is arranged generally parallel with an aircraft central axis and each swivel is limited to provide two use directions of each seat: an oblique sitting mode direction, in which for the second or a subsequent seat in the column; the second or subsequent seat at least partially faces a seat in front in the column; the second or subsequent seat's projection area overlaps the seat in front and the second or subsequent seat's axis makes, with the aircraft central axis and towards the central divider or one of the cabin walls, a sitting mode angle such that a lap belt restraint for taxi, take off and landing is permitted and a more oblique bed mode direction, in which for the second or a subsequent seat in the column; the second or subsequent seat faces to one side of the seat in front; the second or subsequent seat's seat projection area does not overlap the seat in front, but overlaps the second or subsequent seat's own foot rest support; the second or subsequent seat's axis making, with the aircraft central axis and towards the central divider or one of the cabin walls, an angle that is greater than the sitting mode angle; the second or subsequent seat's seat can be extended to bed mode with the foot of the bed at the foot rest support beside the seat in front; and wherein two inside columns of seats face toward the central divider in the oblique bed mode and wherein two outside columns face toward the cabin wall in the oblique bed mode.
