Aircraft fuselage

An aircraft fuselage comprising:

• fore and aft sections of the aircraft fuselage, a barrier wall separating the fore and aft sections and the barrier wall defining an opening therebetween;
• a rail attached to the barrier wall;
• a door moveable across the barrier wall between an open position in which the door is offset from the opening and a closed position in which the door covers the opening;
• a first roller and a second roller each rotatably fixed to the door and moveable on the rail along respective first and second paths to move the door between the open and closed positions;
• wherein the rail includes a first ramp configured to engage the first roller as the first roller moves along the first path, the first ramp configured to direct the first roller towards the barrier wall, and a second ramp configured to engage the second roller as the second roller moves along the second path, the second ramp configured to direct the second roller towards the barrier wall;
• wherein the first roller is configured to engage the first ramp as the second roller engages the second ramp to move the door towards the barrier wall;
• wherein the first and second rollers each have a width extending parallel to a rotational axis of a respective roller, wherein the width of the second roller is greater than the width of the first roller;
• and
• wherein a width difference between the first and second rollers is substantially the same as a height of the second ramp.
