An integrated assembly includes a bumper energy absorber section with crush lobes for abutting a bumper beam, an upper air shutter section with subassembled shutter members movable between closed and open positions, a first actuator mechanism for moving the shutter members between positions, an upper fascia support section with upper leg crush lobe therein above the upper air shutter section, a lower air shutter section with subassembled lower shutter members movable between closed and open positions, a second actuator mechanism for moving the lower shutter members between the positions; and a lower leg energy absorber section attached below the lower air shutter section and configured to abut (or replace) a face of a secondary pedestrian impact bar. The shutter members may be molded to a shutter frame using over molding technology rather than separately, manually assembled.

1. An assembly for a vehicle including a bumper reinforcement beam, comprising: a component including an energy absorbing section and a shutter section, the energy absorbing section including at least one crush section configured to absorb energy when crushed against the bumper reinforcement beam, and the shutter section including active shutter members movable between a closed position to block air flow through the shutter section, an open position to allow air flow through the shutter section, and at least one partially-open position there between for allowing limited air flow;wherein the shutter members each include a cross section having a “Y” shape and further have stiffening ribs extending therefrom for increased cross-sectional stiffness, and with a tip of each of the shutter members each being shaped to closely engage a mating surface on an adjacent one of the shutter members to minimize air leakage when the surfaces engage. 2. The assembly defined in claim 1, wherein the component includes a perimeter frame defining an opening, and including a shutter module incorporating the shutter section which fits matably into the opening and that is attached to the perimeter frame, the shutter module including the active shutter members which are movable between a closed position to block air flow through the shutter perimeter frame, an open position to allow air flow through the perimeter frame, and at least one partially-open position there between for allowing limited air flow. 3. The assembly defined in claim 2, wherein the perimeter frame and shutter module include mating features that frictionally engage upon assembly. 4. The assembly defined in claim 3, wherein the mating features snappingly-engage and attach upon assembly. 5. The assembly defined in claim 1, including at least one linkage arm and linkage for selectively moving the shutter members between the different air flow positions, and wherein the actuator mechanism includes an actuator for moving the linkage. 6. A vehicle comprising: a vehicle frame;a bumper reinforcement beam on a front of the vehicle frame;an engine supported on the vehicle frame and located behind the reinforcement beam;a component including a shutter section positioned above the reinforcement beam and at least as far forward as a rear surface of the reinforcement beam, the shutter section including active shutter members movable between a closed position to block air flow through the shutter perimeter frame, an open position to allow air flow through the perimeter frame, and at least one partially-open position there between for allowing limited air flow.a shutter assembly incorporating the component with the shutter section, the shutter members having a cross section with two spaced arms and a stem defining a “Y” shape and further having stiffening ribs extending between the spaced arms for vane stiffness, a tip of one of the arms having a first surface shaped to closely engage a mating surface on the stem to minimize air leakage when the first and mating surfaces engage; andthe shutter assembly further having at least one linkage arm and linkage for selectively moving the shutter vane members between the different air flow positions. 7. An integrated assembly for a vehicle comprising: a unitary molding including a bumper energy absorber section with a plurality of crush lobes configured to abut a face of a primary bumper reinforcement beam, and at least one shutter section with shutter members configured to move between an air-blocking closed position and an air-flow open position; andan actuator mechanism for moving the shutter members between the closed and open positions; andwherein the shutter members are aerodynamically shaped and configured to move toward the open position upon encountering air pressure from the vehicle's movement even if the actuator mechanism fails. 8. The assembly defined in claim 7, wherein the at least one shutter section includes an upper air shutter section attached above the bumper energy absorber section. 9. The assembly defined in claim 7, wherein the at least one shutter section includes a lower air shutter section attached below the bumper energy absorber section. 10. The assembly defined in claim 7, including the bumper reinforcement beam, and wherein the plurality of crush lobes section includes at least one hollow crush lobe with closed end for absorbing energy upon impact against the bumper reinforcement beam. 11. The assembly defined in claim 10, wherein the plurality of crush lobes are spaced uniformly apart across the bumper reinforcement beam. 12. The assembly defined in claim 7, the unitary molding includes a perimeter frame defining an opening, and wherein the at least one shutter section snaps into the perimeter frame as a modular unit.
