Abstract: A combination hinge and opening bias mechanism for a closure of a vehicle such as a trunk deck lid including a hinge arm attached at one end to the closure with the other end guided by a horizontal track extending beneath an adjacent backlite of the vehicle body. Movement of the end of the hinge arm in the track is controlled by the pivoting of a torsion bar which extends laterally across the closure and with the end of a crankarm portion attached in pivotal relation to the body. During opening movement, the hinged edge of the closure pivots upward and slightly rearward as the elongated portion of the torsion bar rotates about the crankarm end. This upward movement is accompanied by rearward movement of the hinge arm in the track. The simultaneous dual pivoting of the closure moves the hinged edge portion of the closure rapidly upwardly in a substantially vertical direction so as not to contact the adjacent backlite of the vehicle which is only slightly spaced forward thereof.
