Active aerodynamics liftgate spoiler design with multi 4 bar kinematic linkages

An active liftgate spoiler comprising;

• a liftgate of a vehicle, the liftgate includes an upper surface;
• a housing connected to the upper surface of the liftgate;
• a moveable panel connected to the housing by a connection, the moveable panel being moveable between a stowed position, an intermediate position and a deployed position;
• at least one four bar linkage creating at least a portion of the connection between the moveable panel and the housing;
• an actuator connected to the least one four bar linkage for moving the moveable panel between the stowed position, the intermediate position and the deployed position;
• a drive shaft connected between the actuator and the at least one four bar linkage for rotating the four bar linkage and the moveable panel between the stowed position, the intermediate position and the deployed position;
• wherein the at least one four bar linkage further includes a driven link rotatably connected at one end to the drive shaft and at a second end to the moveable panel;
• and
• a follower link rotatably connected between the housing and the moveable panel.
