<p>A vehicle engine shutter assembly, basically of polymeric material, forming a peripheral frame (12), and a plurality of vertical vanes (18) which are rotatable on vertical axes between an open condition and a closed overlapping condition by a horizontally slidable actuator bar (24) which has curvilinear recesses (24a) receiving curved lobes (30) on the vane axles. The closed vanes preferably have notched, interfitting leading edges and trailing edges that interfit to form traps to abate engine noise The vanes (18) and actuator bar (24) are retained in position on the frame (12) by a lock bar (20) that has resilient legs that snap in place.</p> |
