Abstract

An armrest pivot assembly may be provided for a passenger seat. An armrest pivot assembly includes an armrest support defining an aperture having an aperture wall. The aperture wall includes a first pivot-limiting feature. The armrest pivot assembly also includes an armrest pivot within the aperture of the armrest support and rotatable within the aperture relative to the armrest support. The armrest pivot includes a perimeter wall having a second pivot-limiting feature, and the first pivot-limiting feature and the second pivot-limiting feature define a range of rotation of the armrest pivot relative to the armrest support.

First claim

That which is claimed is:

1 . An armrest pivot assembly for a passenger seat, the armrest pivot assembly comprising:
an armrest support defining an aperture comprising an aperture wall, wherein the aperture wall comprises a first pivot-limiting feature; an armrest coupled to an armrest pivot; and the armrest pivot within the aperture of the armrest support, the armrest pivot having a center axis extending through the aperture, wherein the armrest pivot is rotatable relative to the armrest support within the aperture about the center axis, wherein the armrest pivot comprises a perimeter wall, wherein the armrest is rotatable relative to the armrest support about the center axis, wherein the perimeter wall comprises a second pivot-limiting feature, wherein the first pivot-limiting feature and the second pivot-limiting feature define a range of rotation of the armrest pivot relative to the armrest support, wherein the armrest comprises an end, the end comprising a first extension and a second extension, and wherein the first extension and the second extension of the armrest overlap the aperture and the armrest pivot.

2 . The armrest pivot assembly of claim 1 , wherein the first pivot-limiting feature comprises a ridge extending inwards from the aperture wall, and wherein the second pivot-limiting feature of the armrest pivot comprises a recessed surface recessed into the armrest pivot relative to the perimeter wall.

3 . The armrest pivot assembly of claim 2 , wherein the ridge is elongated and comprises a first end and a second end within the aperture, wherein the recessed surface is elongated and comprises a first end and a second end, wherein the first end of the ridge is configured to engage the first end of the recessed surface when the armrest pivot is at first angular position, and wherein the second end of the ridge is configured to engage the second end of the recessed surface when the armrest pivot is at a second angular position.

4 . The armrest pivot assembly of claim 3 , wherein a length of the ridge is less than a length of the recessed surface.

5 . The armrest pivot assembly of claim 2 , wherein the recessed surface comprises a non-linear curvature, and wherein the ridge comprises an innermost surface comprising a non-linear curvature.

6 . The armrest pivot assembly of claim 1 , wherein the armrest pivot is rotatable between a first angular position and a second angular position, wherein the first pivot-limiting feature further comprises an angle adjuster configured to adjust at least one of the first angular position or the second angular position.

7 . The armrest pivot assembly of claim 6 , wherein the angle adjuster comprises a set screw.

8 . The armrest pivot assembly of claim 1 , wherein the armrest pivot comprises at least one support location for the armrest.

9 . The armrest pivot assembly of claim 1 , further comprising a friction device within the aperture between the perimeter wall of the armrest pivot and the aperture wall of the aperture.

10 . The armrest pivot assembly of claim 1 , wherein the armrest pivot further comprises a locking mechanism configured to lock the armrest pivot at an angular position relative to the armrest support.

11 . The armrest pivot assembly of claim 1 , wherein a thickness of a portion of the armrest support defining the aperture is a same as a thickness of the armrest pivot.

12 . The armrest pivot assembly of claim 1 , wherein the armrest pivot comprises a first end and a second end, wherein the perimeter wall extends from the first end to the second end, and wherein the second pivot-limiting feature comprises a recessed surface that is recessed relative to the perimeter wall and extends from the first end to the second end.

13 . The passenger seat of claim 1 , further comprising a first friction device between the first extension of the armrest and the armrest pivot assembly and a second friction device between the second extension of the armrest and the armrest pivot assembly.

14 . An armrest assembly for a passenger seat, the armrest assembly comprising:
an armrest support comprising an aperture and a first pivot-limiting feature within the aperture; an armrest coupled to an armrest pivot; and the armrest pivot comprising:
a first side;
a second side;
a perimeter wall between the first side and the second side, the perimeter wall extending from the first side to the second side,
wherein the armrest pivot is positioned within the aperture and is rotatable relative to the armrest support about a center axis of the armrest pivot extending through the aperture,
wherein the armrest is rotatable relative to the armrest support about the center axis,
wherein a portion of the perimeter wall between the first side to the second side comprises a second pivot-limiting feature configured to engage the first pivot-limiting feature based on rotation of the armrest pivot about the center axis,
wherein the armrest comprises an end, the end comprising a first extension and a second extension, and
wherein the first extension and the second extension of the armrest overlap the aperture and the armrest pivot.

15 . The armrest assembly of claim 14 , further comprising the armrest, the armrest comprising a first extension and a second extension, wherein the first extension is coupled to the first side of the armrest pivot and the second extension is coupled to the second side of the armrest pivot.

16 . An armrest pivot assembly comprising:
an armrest support comprising an aperture and a first pivot-limiting feature within the aperture; an armrest coupled to an armrest pivot; and the armrest pivot within the aperture of the armrest support and rotatable within the aperture relative to the armrest support about a center axis of the armrest pivot extending through the aperture, wherein the armrest is rotatable relative to the armrest support about the center axis, wherein the armrest pivot comprises a second pivot-limiting feature, the second pivot-limiting feature within the aperture defined by the armrest support, wherein the second pivot-limiting feature is configured to selectively engage the first pivot-limiting feature based on rotation of the armrest pivot about the center axis, wherein the armrest comprises an end, the end comprising a first extension and a second extension, and wherein the first extension and the second extension of the armrest overlap the aperture and the armrest pivot.

17 . The armrest pivot assembly of claim 16 , wherein the second pivot-limiting feature is configured to engage the first pivot-limiting feature when the armrest pivot is rotated to a first angular position or a second angular position relative to the armrest support, and wherein the armrest pivot assembly further comprises an angle adjuster at least partially within the aperture and configured to adjust at least one of the first angular position or the second angular position.
