Abstract
An armrest assembly includes an armrest body that defines an interior space. A first shaft extends from a first side of the armrest body along an armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis. A second shaft extends from a second side of the armrest body along the armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis. A rotational damper is located in the interior space of the armrest body and includes a first damper part and a second damper part attached to the first damper part for relative rotational movement. The first damper part is fixed to the first shaft, and the second damper part is fixed to the armrest body.

An armrest assembly comprising:
- an armrest body that defines an interior space;
- a first shaft that extends from a first side of the armrest body along an armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis;
- a second shaft that extends from a second side of the armrest body along the armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis;
- and
- a rotational damper located in the interior space of the armrest body, the rotational damper including a first damper part and a second damper part attached to the first damper part for relative rotational movement,
- wherein the first damper part is fixed to the first shaft, and the second damper part is fixed to the armrest body.
A seat assembly comprising:
- a seat;
- a first bracket and a second bracket that are each fixed to the seat;
- an armrest body that defines an interior space;
- a first shaft that extends from a first side of the armrest body along an armrest axis and is fixed to the first bracket, wherein:
- the armrest body is attached to the first shaft for relative rotational movement about the armrest axis;
- a second shaft that extends from a second side of the armrest body along the armrest axis and is fixed to the second bracket, wherein the armrest body is attached to the second shaft for relative rotational movement about the armrest axis;
- and
- a rotational damper located in the interior space of the armrest body, the rotational damper including a first damper part and a second damper part attached to the first damper part for relative rotational movement, wherein the first damper part is fixed to the first shaft and the second damper part is fixed to the armrest body.
An armrest assembly comprising:
- an armrest body that defines an interior space;
- a first shaft that extends from a first side of the armrest body along an armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis, the first shaft including a rotation support portion that extends from a keyed end to a bushing mount, and a fixed support portion that extends from the bushing mount to an inner end of the first shaft, wherein the fixed support portion of the first shaft is located in the interior space of the armrest body;
- a bushing attached to the bushing mount and fixed on the first shaft, wherein the bushing is located between the rotation support portion of the first shaft and the armrest body;
- a second shaft that extends from a second side of the armrest body along the armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis;
- and
- a rotational damper located in the interior space of the armrest body, the rotational damper including a first damper part and a second damper part attached to the first damper part for relative rotational movement, wherein the first damper part is fixed to the fixed support portion of the first shaft and the second damper part is fixed to the armrest body.
