Abstract

The present invention relates to an assembly of individual seats intended to be installed in an aircraft cabin, the assembly comprising: —a first seat and a second seat, a central console arranged between the first seat and the second seat, the central console comprising a first foot area and a second foot area extending in two opposite directions, —a seat surface width of the first seat being smaller in a portion of the seat opposite the second foot area in relation to a width of a portion of the seat surface opposite the first foot area so as to increase a space between the seat surface of the first seat and the second foot area.

First claim

The invention claimed is:

1. An assembly of individual seats to be installed in an aircraft cabin, said assembly comprising:
a first seat and a second seat facing each other, each seat comprising a seating surface and a backrest,
a central console between the first seat and the second seat, said central console comprising a first foot zone and a second foot zone extending in two opposite directions,
the first foot zone being associated with the first seat facing an opening of the first foot zone, said first foot zone being delimited by an upper wall forming a table for a passenger in the second seat with no access to the opening of the first foot zone,
the second foot zone being associated with the second seat facing an opening of the second foot zone, said second foot zone being delimited by an upper wall forming a table for a passenger in the first seat with no have access to the opening of the second foot zone,
characterized in that a width of the seating surface of the first seat is smaller in a part of the seating surface facing the second foot zone than a width of a part of the seating surface facing the first foot zone as to increase a space between the seating surface of the first seat and the second foot zone,
and in that said assembly comprises a double-door module provided with two doors movable between a stored position and an extended position in which a door is able of transversely closing a corresponding space between a seat and the central console, the doors at least partly overlapping inside the double-door module when the doors are in the stored position,
wherein in the part of the seating surface of the first seat facing the second foot zone, at least a portion of a front edge of said seating surface has a curved shape, this curved portion of the front edge of the seating surface is located in the extension of a rectilinear portion of the front edge facing the first foot zone, the curved portion extending from the middle of the seating surface of the first seat up to the extremity of the seating surface of the first seat positioned on the side of the second foot zone, the curved portion being defined by a radius of curvature of about 70 cm,
wherein a width of the seating surface of the second seat is smaller in a part facing the first foot zone than a width of a part of the seating surface facing the second foot zone so as to increase a space between the seating surface of the second seat and the first foot zone,
wherein in the part of the seating surface of the second seat facing the first foot zone, at least a portion of a front edge of said seating surface has a curved shape, this curved portion of the front edge of the seating surface is in the extension of a rectilinear portion of the front edge facing the second foot zone, the curved portion extending from the middle of the seating surface of the second seat up to the extremity of the seating surface of the second seat positioned on the side of the first foot zone, the curved portion being defined by a radius of curvature of about 70 cm.

2. The assembly of seats according to claim 1 , characterized in that each seat has side edges aligned with side edges of the other seat.

3. The assembly of seats according to claim 1 , characterized in that it comprises two retractable panels movable between a stored position and an extended position in which a panel closes a corresponding space above a side edge of a seat on the side of an aisle.

4. The assembly according to claim 1 , characterized in that a ratio of a sum of a width of the central console and two thicknesses of fixed shells surrounding the backrests divided by a length of one pitch of said assembly of two seats is between 25% and 40%.

5. The assembly of seats according to claim 1 , characterized in that, as a seat is convertible between a seating position and a lying position, a space between the seat and the central console is to be filled by at least a portion of the seat when the latter is in the lying position.

6. The assembly of seats according to claim 5 , characterized in that, when a seat is in the lying position, at least a portion of the seating surface is vertically superimposed with a closed foot zone on the side of the seat comprising the seating surface.

7. The assembly of seats according to claim 1 , characterized in that, as a lying surface is formed by at least a portion of the seating surface and at least a portion of the backrest when the seat is in the lying position as well as an internal wall of the open foot zone associated with said seat, a ratio of an area of the lying surface to an area of a living space associated with a seat is between 90% and 100%.

8. The assembly of seats according to claim 1 , characterized in that the central console has a partition wall.

9. An aircraft cabin, characterized in that it comprises at least one column of assemblies of seats as defined according to claim 1 .
