A hinge assembly for rotatably supporting a decklid relative to a body of a vehicle includes a damping mechanism for damping movement of the decklid relative to the body. The damping mechanism includes a damping clip attached to a bracket of the hinge assembly, and a damping bumper attached to a hinge box of the hinge assembly. Movement of the bracket from a closed position into an open position brings the damping bumper into engagement with the damping clip. The damping bumper spreads and/or elastically deforms the damping clip to absorb energy and dampen the movement of the bracket and/or the decklid.
