Abstract
A counterbalanced hinge assembly for rotatably supporting a decklid of a vehicle includes a hinge box and a support member rotatably attached to the hinge box. A linkage system interconnects the hinge box and the support member, and includes a wind-up link rotatably attached to the hinge box for rotation about a spring axis, and a driven link interconnecting the wind-up link and the support member. A planar coil spring is coiled about the spring axis and is coupled to both the hinge box and the wind-up link. The planar coil spring applies a torque to the wind-up link to rotate the wind-up link about the spring axis to assist movement of the support member from the closed position into the open position.
