Abstract

An aircraft lavatory unit includes a second side wall having a long-space-section side wall and a wide-space-section side wall. The long-space-section side wall forms, between it and a first side wall, a long space section that extends with a uniform width. The wide-space-section side wall forms, between it and the first side wall, a wide space section that has a greater width than the long space section. A toilet bowl is arranged at an end in the extending direction of the long space section. A wash basin is arranged at one end in the width direction of the wide space section. A doorway is arranged in a front wall so as to be located closer to the other end in the width direction of the wide space section.

First claim

What is claimed is:

1. An A structure for arranging the aircraft lavatory unit, the
structure comprising:
a fuselage of an aircraft including:
a longitudinal aisle extending in a longitudinal direction of the fuselage;
seat groups having a plurality of seat rows arranged in rows in the longitudinal direction of the fuselage on both left and right sides of the longitudinal aisle, the seat rows having a plurality of seats facing a front of the fuselage and arranged in rows in a latitudinal direction of the fuselage;
a latitudinal aisle extending in the latitudinal direction from a boarding entrance behind the seat groups; and
a rear seat row, constituted by a rearmost seat row of at least one of the seat groups on the left and right sides of the longitudinal aisle, having a seat, located near the longitudinal aisle, removed in comparison to seat rows located in front of the rear seat row,
the aircraft lavatory unit comprising
a body frame including:
a bottom wall;
a first side wall and a second side wall extending from the bottom wall and facing each other;
a rear wall connecting the side walls at one end; and
a front wall connecting the side walls at another end and having a doorway;
the second side wall including a long-space-section side wall located near the rear wall, the long-space-section side wall extending from the bottom wall to at least a height greater than a height of a backrest of an aircraft the seat when in an upright position, the second side wall forming, between the long-space-section side wall and the first side wall, a long space section extending linearly with a uniform width and a wide-space-section side wall located near the front wall, the wide-space-section side wall extending from the bottom wall, connecting to the long-space-section side wall and forming, between the wide-space-section side wall and the first side wall, a wide space section having a greater width than the long space section;
the body frame having a toilet bowl and a wash basin arranged therein to form a lavatory;
the toilet bowl being arranged at an end in an extending direction of the long space section near the rear wall;
the wash basin being arranged at one end in a width direction of the wide space section; and
a width of the body frame where the long-space-section side wall exposed to an outer side of the body frame is located being set to minimum dimensions sufficient for ensuring that the long space section has a width allowing a person to come and go between the doorway and the toilet bowl and allowing a person to sit on the toilet bowl,
the aircraft lavatory unit being arranged so that the long-space-section side wall is located adjacent to a backrest of the seat in the rear seat row, the wide-space-section side wall is located in the location of the removed seat, the first side wall faces the latitudinal aisle, and the front wall faces the longitudinal aisle.

2. The structure for arranging the aircraft lavatory unit according to claim 1 , wherein the doorway is arranged so as to be closer to another end in the width direction of the wide space section.

3. The structure for arranging the aircraft lavatory unit according to claim 2 , wherein the body frame further has a ceiling wall forming a ceiling of the lavatory; and the long-space-section side wall extends from the bottom wall to the ceiling wall.

4. The structure for arranging the aircraft lavatory unit according to claim 3 , wherein a luggage compartment is provided on an outer surface located on an opposite side from the long space section of the long-space-section side wall at a location higher than the height of the backrest of the aircraft seat when in an upright position.

5. The structure for arranging the aircraft lavatory unit according to claim 2 , wherein the body frame further has a ceiling wall forming a ceiling of the lavatory; the long-space-section side wall extends to a height greater than the height of the backrest of the aircraft seat when in an upright position;
a projecting wall section projecting from an upper end of the long-space-section side wall in a direction away from the first side wall and connecting to the ceiling wall and the rear wall is provided; and
a storage shelf for the lavatory is formed at a location inside the projecting wall section.

6. The structure for arranging the aircraft lavatory unit according to claim 5 , wherein the wide-space-section side wall has an extending surface section extending from an end of the long-space-section side wall near the wide-space-section side wall in a direction away from the first side wall, and a side wall section bending away from the extending surface section, extending in parallel with the first side wall, and connecting to the front wall; and the projecting wall section has an undersurface section extending from the upper end of the long-space-section side wall in a direction away from the first side wall, and a side wall section bending away from the undersurface section, extending in parallel with the first side wall, and continuously connecting with the ceiling wall and the side wall section of the wide-space-section side wall.

7. The structure for arranging the aircraft lavatory unit according to claim 6 , wherein the width of the body frame where the wide space section is located is set to minimum dimensions sufficient for ensuring that the wide space section has a width allowing a person to pass through between the wash basin and the first side wall and allowing a person to come and go between the doorway and the long space section.

8. The structure for arranging the aircraft lavatory unit according to claim 7 , wherein the width of the body frame where the long-space-section side wall exposed to the outer side of the body frame is located is from 600 mm to 750 mm.

9. The structure for arranging the aircraft lavatory unit according to claim 1 , wherein the body frame further has a ceiling wall forming a ceiling of the lavatory; and the long-space-section side wall extends from the bottom wall to the ceiling wall.

10. The structure for arranging the aircraft lavatory unit according to claim 9 , wherein a luggage compartment is provided on an outer surface located on an opposite side from the long space section of the long-space-section side wall at a location higher than the height of the backrest of the aircraft seat when in an upright position.

11. The structure for arranging the aircraft lavatory unit according to claim 1 , wherein the body frame further has a ceiling wall forming a ceiling of the lavatory;
the long-space-section side wall extends to a height greater than the height of the backrest of the aircraft seat when in an upright position;
a projecting wall section projecting from an upper end of the long-space-section side wall in a direction away from the first side wall and connecting to the ceiling wall and the rear wall is provided; and
a storage shelf for the lavatory is formed at a location inside the projecting wall section.

12. The structure for arranging the aircraft lavatory unit according to claim 11 , wherein the wide-space-section side wall has an extending surface section extending from an end of the long-space-section side wall near the wide-space-section side wall in a direction away from the first side wall, and a side wall section bending away from the extending surface section, extending in parallel with the first side wall, and connecting to the front wall; and
the projecting wall section has an undersurface section extending from the upper end of the long-space-section side wall in a direction away from the first side wall, and a side wall section bending away from the undersurface secti
