Airbus has filed a 13 pages patent application with the US Patent and Trademark Office on March 26, 2015 which illustrating the “Elevated deck structure” passengers seat arrangement. The inventors are Benedict Kircher, Paul Edwards and Stephan Sontag.
According to the paper published on October 1, 2015, the passenger seats arrangement comprises of two levels, a first lower level, and the second elevated level. Each of the seats comprises a supporting surface for upright seating as well as the reclined laying position.
Airbus: In modern means of transport, in particular in aircraft, it is very important from an economic point of view to make optimum use of available space in a passenger cabin.
This U.S Patent #: US20150274298 aim to propose the position of an elevated deck structure on a main deck floor in the passenger cabin of a wide-body aircraft for providing a mezzanine seating area. Airbus believed that this would permits optimum use of the space in a passenger cabin of an aircraft with high level of comfort for the passengers.
“Simultaneously, as compared to usual one level seat arrangements, the passenger seat arrangement allows the installation of a higher number of seats within a given installation space inside a passenger cabin of a vehicle. The passenger seat arrangement thus is in particular suitable for use in, for example the Business Class area of an aircraft cabin.” Airbus further illustrated.
Interestingly, as mentioned in the application paper, the passenger seat arrangement may further comprise an ottoman arranged at the first lowered level in front of the first seat. The ottoman then may be used for providing an additional feet supporting portion for the passenger occupying the first seat. Further, the ottoman may be equipped with storage compartments for storing items such as newspapers and the like. A stair or ladder for providing access to the second seat may be mounted to a side surface of the ottoman.
However, Airbus has yet to make official announcement on the application of this concept into the actual aircraft.
