Abstract

A counterbalanced decklid hinge assembly for rotatably supporting a decklid relative to a vehicle includes a torque rod extending between a first hinge box and a second hinge box. A support member is rotatably supported by each of the first and second hinge boxes. A linkage system interconnects one axial end of the torque rod to one of the support members. A lever is attached to and rotatable with the other axial end of the torque rod. A clamping block attaches the torque rod to one of the lever and the linkage system, and is configured to provide an infinite degree of rotational adjustment therebetween to infinitely adjust the pre-loaded torque rod.

Description

technical field [0001] The present invention relates to a hinge assembly for rotatably supporting a decklid of a vehicle, and more particularly to a balanced hinge assembly having a twisted torque rod extending between a pair of hinge boxes for Apply opening force to the trunk lid. Background technique [0002] A balanced decklid assembly generally includes at least one torque rod extending between a pair of hinge boxes. A support member is rotatably attached to and supported by each of the hinge boxes. One end of the torque rod is bent to define a crimped end that engages one of the hinge boxes, and the other end of the torque rod is bent to define a looped end that engages one of the support members. The torque rod is twisted during assembly and fixed in position relative to the hinge box to preload the torque rod. The preloaded torque rod is used as a spring to unwind, thereby applying torque to the support member to help open the decklid. [0003] The amount of torqu...
