Abstract

An aircraft interior assembly comprising a fixed element, a sliding element movable between a lockable position and a released position, and a latch mechanism. The latch mechanism comprises a locking arm, mounted on one of the fixed element and the sliding element, which is rotatable around a rotating axis between a locked position and an unlocked position. The latch mechanism further comprises an engagement plate, mounted on the other of the fixed element and the sliding element. When the sliding element is in the lockable position and the locking arm is in the locked position, the locking arm contacts the engagement plate to prevent the sliding element moving out of the lockable position. Conversely, when the sliding element is in the lockable position and the locking arm is in the unlocked position, the locking arm is not in contact with the engagement plate, and the sliding element is free to move out of the lockable position.

Claims (22)

1 . An aircraft interior assembly comprising:

a fixed element;

a sliding element movable between a lockable position and a released position;

a latch mechanism comprising:

a locking arm, mounted on one of the fixed element and the sliding element, the locking arm having an engagement end and being rotatable around a rotating axis between a locked position and an unlocked position;

an engagement plate mounted on the other of the fixed element and the sliding element, the engagement plate comprising an engaging surface;

wherein when the sliding element is in the lockable position and the locking arm is in the locked position, the engagement end of the locking arm contacts the engaging surface of the engagement plate to prevent the sliding element moving out of the lockable position;

wherein when the sliding element is in the lockable position and the locking arm is in the unlocked position, the engagement end of the locking arm is not in contact with the engaging surface of the engagement plate so that the sliding element is free to move out of the lockable position; and

wherein the engaging surface of the engagement plate is shaped such that, when the sliding element is in the lockable position, the surface is an arc of a circle having as its center the rotating axis of the locking arm.

2 . An aircraft interior assembly as claimed in claim 1 , wherein the locking arm is mounted on the fixed element, and the engagement plate is mounted on the sliding element.

3 . An aircraft interior assembly as claimed in claim 1 , wherein the sliding element is movable in a plane perpendicular to the rotating axis of the locking arm.

4 . An aircraft interior assembly as claimed in claim 1 , wherein the end of the locking arm opposite the engagement end comprises a locking area which when pushed rotates the locking arm into the locked position.

5 . An aircraft interior assembly as claimed in claim 1 , wherein the end of the locking arm opposite the engagement end comprises an unlocking area which when pushed rotates the locking arm into the unlocked position.

6 . An aircraft interior assembly as claimed in claim 5 , wherein the end of the locking arm opposite the engaging end comprises a rocker.

7 . An aircraft interior assembly as claimed in claim 1 , wherein the surface of the engagement end of the locking arm is an arc of a circle having as its center the rotating axis of the locking arm.

8 . An aircraft interior assembly as claimed in claim 1 , wherein the engagement plate is adjustably mounted on the fixed element or sliding element so that a distance between the engaging surface of the engagement plate and the rotating axis of the locking arm is adjustable.

9 . An aircraft interior assembly as claimed in claim 1 , wherein the locking arm is removably mounted on the fixed element or sliding element.

10 . An aircraft interior assembly as claimed in claim 1 , wherein, when the sliding element is in the released position and the locking arm is in the locked position, movement of the sliding element into the lockable position causes the locking arm to be rotated out of the locked position.

11 . An aircraft interior assembly as claimed in claim 9 , arranged so that, during movement of the sliding element into the lockable position the engagement plate is brought into contact with the locking arm to rotate the locking arm out of the locked position.

12 . An aircraft interior assembly as claimed in claim 9 , wherein the locking arm is biased to return to the locked position.

13 . An aircraft interior assembly as claimed in claim 1 , wherein the sliding element is a sliding door.

14 . An aircraft interior assembly as claimed in claim 1 , wherein the aircraft interior assembly is an aircraft seat assembly.
