A patent for diagonal seating rows has been filed at the US Patent and Trademark Office. For wide-body aircraft, this arrangement allows a possible 12-abrest (3-6-3) configuration in Economy Class. Welcome to the slave ship! In addition, the drawing features triangular lavatories for optimal room usage.
Let’s hope that no carrier will adopt this strange seating configuration!
A seating arrangement for a vehicle, especially an aircraft, in which seats are arranged in a plurality of generally parallel ranks, each rank extending in a fore-and-aft direction, and in a plurality of rows, each row extending at an angle other than a right angle with respect to said fore-and-aft direction and wherein adjacent seats in a row overlap in a transverse direction. In the preferred embodiment, the seats of a row also overlap in said fore-and-aft direction and include a truncated armrest at one side of the seat arranged to fit behind an adjacent seat. The seats further include an armrest at the other side of the seat, the armrest comprising a bar which extends from the rear of the seat so that a portion of one seat is located beneath the armrest provided at said other side of an adjacent seat.
