Abstract
A vehicle tailgate movement assist mechanism may include a tailgate configured to rotate between opened and closed positions, and a tailgate cam lever arm fixedly connected to a bottom area of the tailgate. A bell crank may be pivotally anchored at one end thereof to a vehicle body, and a strut may be pivotally anchored at one end thereof to the vehicle body and pivotally connected at an opposite end thereof to the bell crank. With the tailgate cam lever arm, bell crank and strut configured as discussed, rotation of the tailgate from a closed to an opened position simultaneously rotates the tailgate cam lever arm to contact and rotate the bell crank to actuate the strut to reduce an opening speed of the tailgate.
