Abstract
There is disclosed a vehicle engine shutter assembly, basically of polymeric material forming a peripheral frame, a plurality of vertical vanes which are rotatable on vertical axes between an open condition and a closed overlapping condition by a horizontally slidable actuator bar which has curvilinear recesses receiving curved lobes on the vane axles. The closed vanes preferably have notched, interfitting leading edges and trailing edges that interfit to form said traps to abate engine noise. The vanes and actuator bar are retained in position on the frame by a lock bar that has resilient legs than snap in place.
