Claim 0:
1. An arm rest assembly, comprising:
a rotationally fixed frame member defining a rotational axis for an arm rest;
an arm rest member including a rotational member rotatably disposed through the frame member, the rotational member configured to rotate around the rotational axis, and the rotational member having a rigid outer circumferential surface comprising an annular shoulder bearing against one side of the frame member;
a separate arm rest member removably attached to the rotational member, the separate arm rest member receiving one end of the rotational member, and the separate arm rest member bearing against an opposing side of the frame member such that the frame member is captured between the annular shoulder and the separate arm rest member;
a groove formed in the outer circumferential surface of the rotational member; and
an O-ring disposed in the groove;
wherein the O-ring is disposed between the outer circumferential surface of the rotational member and an inner circumferential surface of the frame member;
wherein a tolerance between the outer circumferential surface of the rotational member and the inner circumferential surface of the frame member is such that the O-ring is held in the groove in a compressed state and in frictional engagement with each of the rotational member and the frame member; and
wherein the arm rest comprising the arm rest member and the separate arm rest member each configured to rotate between a stowed condition and a deployed condition for receiving and supporting an arm of a user.
