An active front deflector assembly for a vehicle, comprising: at least one deflector panel, where the deflector panel selectively deploys and retracts between a deployed position and a stowed position, where the deployment of the deflector panel improves aerodynamics; at least two linkage assemblies (12, 14) attached to the deflector panel and to the vehicle, each linkage assembly (12, 14) forming a trapezium shape when in the deployed position; a drive shaft operably coupled to the at least two linkage assemblies (12, 14) wherein the drive shaft transmits the drive from one linkage assembly (12, 14) to the other; an actuator operably coupled to the linkage assemblies (12, 14), where the actuator is in communication with the vehicle and deploys and retracts the deflector panel under predetermined conditions; wherein the at least two linkage assemblies (12, 14) each further comprise: a coupler link, where the coupler link is attached to an upper spine of the deflector panel; a fixed base link, where the fixed base link is attached to the vehicle; a drive link pivotably connected to the coupler link and fixed base link; and a follower link pivotably connected to the coupler link and fixed base link; where the coupler link, drive link, follower link, and fixed base link are at predetermined angles and ratios to each other to move the deflector panel between the deployed and retracted position; characterized in that, when in the deployed position, the angle between the fixed base link and drive link in the deployed position is 75-85 degrees, and/or the length of the fixed base link is two times the length of the coupler link, and/or the drive link is three times the length of the coupler link, and/or the follower link is 3.875 times the length of the coupler link; and wherein the actuator has object detection and de-clutches upon impact at a predetermined force the deflector panel to rotate freely out of the way to prevent damage, wherein this motion is achieved with the geometry of the linkage systems and the ratio of the links to each other. at least one deflector panel, where the deflector panel selectively deploys and retracts between a deployed position and a stowed position, where the deployment of the deflector panel improves aerodynamics; at least two linkage assemblies (12, 14) attached to the deflector panel and to the vehicle, each linkage assembly (12, 14) forming a trapezium shape when in the deployed position; a drive shaft operably coupled to the at least two linkage assemblies (12, 14) wherein the drive shaft transmits the drive from one linkage assembly (12, 14) to the other; an actuator operably coupled to the linkage assemblies (12, 14), where the actuator is in communication with the vehicle and deploys and retracts the deflector panel under predetermined conditions; wherein the at least two linkage assemblies (12, 14) each further comprise: a coupler link, where the coupler link is attached to an upper spine of the deflector panel; a fixed base link, where the fixed base link is attached to the vehicle; a drive link pivotably connected to the coupler link and fixed base link; and a follower link pivotably connected to the coupler link and fixed base link; where the coupler link, drive link, follower link, and fixed base link are at predetermined angles and ratios to each other to move the deflector panel between the deployed and retracted position; characterized in that, a coupler link, where the coupler link is attached to an upper spine of the deflector panel; a fixed base link, where the fixed base link is attached to the vehicle; a drive link pivotably connected to the coupler link and fixed base link; and a follower link pivotably connected to the coupler link and fixed base link; where the coupler link, drive link, follower link, and fixed base link are at predetermined angles and ratios to each other to move the deflector panel between the deployed and retracted position; characterized in that, when in the deployed position, the angle between the fixed base link and drive link in the deployed position is 75-85 degrees, and/or the length of the fixed base link is two times the length of the coupler link, and/or the drive link is three times the length of the coupler link, and/or the follower link is 3.875 times the length of the coupler link; and wherein the actuator has object detection and de-clutches upon impact at a predetermined force the deflector panel to rotate freely out of the way to prevent damage, wherein this motion is achieved with the geometry of the linkage systems and the ratio of the links to each other.
