A novel active hood system is disclosed. The active hood system is designed such that in the event of a pedestrian/vehicle accident, the active hood system will soften the impact between the pedestrian and the vehicle by moving the vehicle hood into an elevated position. In some embodiments, the active hood system is constructed such that during a pedestrian/vehicle collision, the active hood system will raise the vehicle hood into an elevated position by having the hood move through a first travel distance and a second travel distance. The active hood system includes an actuator and a hinge. The actuator may be attached to the hinge. The actuator is designed such that if it is deployed, the actuator will raise the hood into the elevated position. Additional embodiments may also be made in which the actuator is vented during deployment. A dampener is also added to the active hood system. The dampener is designed to dampen the movement of the hood as the hood is moved through the second travel distance.

What is claimed and desired to be secured by United States Letters Patent is: 1. An active hood system comprising: an actuator attachable to a vehicle, the actuator being capable of moving the vehicle hood from a first position to a second, elevated position; and a dampener constructed to dampen the movement of the vehicle hood when said hood is actuated from the first position to the second position, wherein the dampener comprises a deformable material housed within a retention bracket; a retention flange positioned within the retention bracket; and, a cable connected the retention flange, the cable being attachable to the vehicle hood. 2. An active hood system as in claim 1 wherein the system is designed such that impact between a pedestrian and a vehicle hood causes the actuator to compress. 3. An active hood system as in claim 1 wherein the deformable material is positioned such that if the vehicle hood is moved into the elevated position, the dampening material is crushed between the retention flange and the retention bracket. 4. An active hood system as in claim 1 further comprising a hinge that is connected to or positioned proximate the actuator, the hinge constructed to extend when the hood is moved into the second elevated position. 5. An active hood system as in claim 4 wherein the hinge comprises an actuator supporting member that holds the actuator and a base that supports the actuator. 6. An active hood system comprising: an actuator attachable to a vehicle, the actuator being capable of moving the vehicle hood from a first position to a second, elevated position; a dampener constructed to dampen the movement of the vehicle hood when said hood is actuated from the first position to the second position; and a hinge that is connected to or positioned proximate the actuator, the hinge constructed to extend when the hood is moved into the second elevated position, wherein, the hinge comprises an actuator supporting member that holds the actuator and a base that supports the actuator, and wherein the supporting member includes at least one slot that extends into a central aperture. 7. An active hood system as in claim 4 wherein the actuator comprises at least one telescoping stage. 8. An active hood system as in claim 4 wherein the hinge includes at least one linkage. 9. An active hood system as in claim 8 further comprising a holding member that holds the linkages in a contracted position. 10. An active hood system as in claim 9 wherein the system is constructed such that deployment of the actuator moves the linkages from the contracted position into an extended position. 11. An active hood system as in claim 9 wherein the hinge comprises a locking member. 12. An active hood system as in claim 11 wherein the hinge comprises a rotation pin. 13. An active hood system as in claim 9 wherein the actuator is attached to the hinge via an actuator mounting member. 14. An active hood system as in claim 8 wherein the linkages comprise at least one tab. 15. An active hood system as in claim 4 wherein the actuator comprises a cylindrical groove having at least one mating flat. 16. An active hood system as in claim 4 wherein the hinge comprises at least one tab. 17. An active hood system comprising: an actuator attachable to a vehicle, the actuator being capable of moving the vehicle hood from a first position to a second, elevated position; and a dampener constructed to dampen the movement of the vehicle hood when said hood is actuated from the first position to the second position, wherein the dampener comprises a deformable tube; a cable that is attachable to the vehicle hood; and a deforming ball within the deformable tube, the deforming ball being attached to the cable. 18. An active hood system as in claim 17 wherein the deforming ball is positioned such that if the vehicle hood is moved into the elevated position, the deforming ball deforms the deformable tube. 19. An active hood system comprising: an actuator attachable to a vehicle, the actuator being capable of raising the vehicle hood into a second elevated position by moving the hood through a first travel distance and a second travel distance, wherein, the actuator comprises at least one telescoping stage; and a dampener constructed to dampen the movement of the vehicle hood during the travel of the hood through the second travel distance, wherein, the dampener comprises a deformable material housed within a retention bracket, a retention flange positioned within the retention bracket, and, a cable connected to the retention flange, the cable being attachable to the vehicle hood. 20. An active hood system as in claim 19 wherein the deformable material is positioned such that if the vehicle hood is moved through the second travel distance, the dampening material is crushed between the retention flange and the retention bracket. 21. An active hood system as in claim 19 further comprising a hinge that is connected to or positioned proximate the actuator, the hinge constructed to extend when the hood is moved into the second elevated position. 22. An active hood system as in claim 21 wherein the hinge includes at least one linkage. 23. An active hood system as in claim 22 wherein the linkage comprises at least one tab. 24. An active hood system as in claim 22 wherein the hinge further comprises a holding member that holds the linkages in a contracted position. 25. An active hood system as in claim 24 wherein the system is constructed such that deployment of the actuator moves the linkages from the contracted position into an extended position. 26. An active hood system as in claim 24 wherein the hinge further comprises a locking member. 27. An active hood system as in claim 26 wherein the locking member is a shear pin. 28. An active hood system as in claim 26 wherein the locking member is re-installable. 29. An active hood system as in claim 24 wherein the actuator is attached to the hinge via an actuator supporting member that is added to the hinge. 30. An active hood system as in claim 21 wherein the hinge further comprises a rotation pin. 31. An active hood system as in claim 21 wherein the hinge comprises an actuator supporting member that holds that actuator and a base that supports the actuator. 32. An active hood system as in claim 31 wherein the supporting member includes at least one slot that extends into a central aperture.
