An articulating arm assembly for a passenger seat, the articulating arm assembly comprising:

• a static portion attachable to the passenger seat;
• a rotation portion attached to the static portion such that the rotation portion is pivotable about a rotation axis, wherein the static portion defines a first end of the articulating arm assembly along the rotation axis and wherein the rotation portion defines a second end of the articulating arm assembly along the rotation axis;
• an arm body attached to the rotation portion, wherein the rotation portion and the arm body are movable between a stowed position and a deployed position;
• and
• a wiring portion disposed inside the arm body and extending from the arm body into the rotation portion, wherein the wiring portion is disposed such that the wiring portion extends parallel to the rotation axis from the rotation portion toward and into the static portion,
• wherein the static portion comprises a main portion and a housing portion having a cavity, wherein the main portion defines an internal cavity having a depth along the rotation axis and configured to receive a pin, the housing portion comprising a recessed area that is at least partially cylindrical, is outside of the internal cavity of the main portion, and corresponds to an external surface of the rotation portion,
• wherein the static portion further comprises a plunger and a spring located within the cavity of the housing portion, and
• wherein the spring is configured to cause the plunger to push the rotation portion away from the stowed position.
