Shutter system for vehicle grille

1. An apparatus for use with a vehicle grille comprising:

a frame;

a pair of shutters connected to said frame and pivotable relative thereto between a first position and a second position about a pivot axis, each of said shutters including an engagement member, said shutters restricting airflow through the vehicle grille in said first position and allowing airflow through the vehicle grille in said second position; and

a drive mechanism driving said shutters between said first and second positions, said drive mechanism including a drive shaft rotating relative to said frame and a drive member engaging said drive shaft, said drive member moving linearly relative to said frame, said drive member including an arcuate slot slidably engaging one of said engagement members,

wherein said shutters are connected to said frame for pivotal motion in opposite directions relative to each other between said first and second positions.

2. The apparatus of claim 1 , wherein said engagement member is spaced apart from said pivot axis.

3. The apparatus of claim 1 , wherein said pair of shutters form a generally V-shape during movement between said first and second positions.

4. The apparatus of claim 1 , wherein said drive member includes a pair of arcuate slots, each of said arcuate slots correspond to each of said pair of shutters, said pair of arcuate slots having different arcuate shapes from each other.

5. The apparatus of claim 1 , wherein said drive shaft and said drive member cooperate to form a rack-and-pinion mechanism.

6. The apparatus of claim 1 , wherein each of said shutters includes a reinforcement rib.

7. The apparatus of claim 1 , further comprising a spring member configured to urge at least one of said shutters toward said second position.

8. The apparatus of claim 1 , further comprising a protective member at least partially encasing said drive member.

9. A vehicle comprising:

a vehicle body including a front end;

a grille mounted to said front end; and

a shutter assembly controlling airflow through said grille and including a frame, a plurality of shutters and a drive mechanism, said frame being mounted to said vehicle proximate said grille, said shutters being pivotably supported by said frame and including opposing elongated first and second sides and opposing first and second ends, said drive mechanism including an actuator driving a drive member, said drive member being coupled to each of said shutters at an engagement location disposed along said first end and between said first and second sides to pivot said shutters relative to said grille between a first position and a second position,

wherein said drive mechanism includes a drive shaft rotating relative to said frame and engaging said drive member to move said drive member linearly relative to said frame, and wherein said drive shaft includes a first geared portion and said drive member includes a second geared portion engaging said first geared portion.

10. The vehicle of claim 9 , wherein said shutter assembly includes a plurality of pins and said drive member includes first and second arcuate slots slidably engaging said pins, each of said pins engaging a corresponding one of said shutters at said engagement location.

11. The vehicle of claim 9 , wherein said shutter includes a reinforcement rib.

12. The vehicle of claim 9 , further comprising a spring member configured to urge said shutter toward said second position.

13. The vehicle of claim 9 , wherein a first one of said shutters pivots into said first position in a first direction relative to said frame and a second one of said shutters pivots into said first position in a second direction relative to said frame.

14. The vehicle of claim 9 , wherein said shutter assembly includes a protective member at least partially encasing said drive member.

15. An apparatus for use with a vehicle grille comprising:

a frame;

a pair of shutters connected to said frame and pivotable relative thereto between a first position and a second position, each of said shutters including an engagement member, said shutters restricting airflow through the vehicle grille in said first position and allowing airflow through the vehicle grille in said second position; and

a drive mechanism driving said shutters between said first and second positions, said drive mechanism including a drive shaft rotating relative to said frame and a drive member engaging said drive shaft, said drive member moving linearly relative to said frame, said drive member including a pair of arcuate slots, each of said arcutate slots slidably engaging said engagement member of a corresponding one of said shutters, said pair of arcuate slots having different arcuate shapes from each other.

16. The apparatus of claim 15 , wherein said engagement members are spaced apart from said pivot axis.

17. The apparatus of claim 15 , wherein said drive shaft and said drive member cooperate to form a rack-and-pinion mechanism.

18. The apparatus of claim 15 , further comprising a spring member configured to urge both of said shutters toward said second position.

19. The apparatus of claim 15 , further comprising a protective member at least partially encasing said drive member.

20. The apparatus of claim 15 , wherein each of said shutters includes a reinforcement rib.
