Abstract
A stabilizing arm for use in power operated doors in mass transit vehicles. Doors are of the type where a door panel is moved out of an opening in the car side wall to an opened position outside the car side wall. Stabilization is achieved by moving a rotating arm out of the side wall and capturing the panel in its opened position, thereby minimizing possible hazards in passenger passing through the car opening and damage to the doors either by passengers or others. Operation of the arm is sequenced in the door opening cycle.
