Abstract: An improved articulated coupling assembly which connects the ends of a motor driven torsion bar to a pair of headlamp concealment door crank arm pivot pins. A plastic spool member, having a square sectioned passage terminated in an outboard socket, is telescopically mounted at each end of the torsion bar. Each crank arm pivot pin has a ball portion formed on its inboard end for reception in its associated spool socket. A spring wire clip, removably snapped on the spool member, has a cross pin portion received in aligned apertures in the spool socket and a registering diametrical slot in the ball portion. The coupling provides limited axial and universal movement of the spool member during opening and closing of the doors. Removal of the spring wire clip allows the spool member to slide inboard on the bar freeing its crank arm pivot pin for ready removal.
