Abstract: An automobile trunk lid is mounted for swinging on the automobile body between closed and open positions with respect to the trunk compartment. Each hinge includes a slotted hinge arm attached to the underside of the lid and a slotted body bracket attached to the body adjacent one side of the trunk compartment. A follower on the hinge arm projects into and is adapted to travel along the slot in the body bracket while a follower on the body bracket projects into the slot in the hinge arm. As the lid is opened, the followers and slots coact to first elevate the forward portion of the lid away from the body and then to allow the lid to swing open about an instantaneously changing axis. A spring, a cam and a cable coact to apply a spring-assist to the lid during opening, the cam and cable acting to compensate for the spring rate of the spring as the lid moves and its center of gravity changes in space.
