Abstract
A ceiling grille for directing conditioned air from an air conditioning unit mounted upon the roof of a motor vehicle wherein comfort air is delivered into a plenum located inside the vehicle. The plenum has front and rear deflector vanes rotatably mounted therein for directing comfort air into the passenger compartment. Each vane has a rocker arm that is connected through suitable linkage to a cam follower. Each cam follower, in turn, rides on the cam face of a motor driven cam. The profile of the cam face is contoured to position the two vanes to control the direction of comfort air flow into the passenger compartment.
