ABSTRACT:
A double pivot hinge for rotatably mounting a door to a vehicle body for sequential movement between closed, mid open, and full open positions in an uninterrupted manner. The hinge assembly includes a U-shaped link having a bight portion joining first and second legs with body and door hinge leafs each pivoted by a pin to respective first and second legs. A cam plate is fixed on each leaf, with each plate defining an arcuate cam edge having its center on its associated pin axis. A locking bar, supporting a cam follower at one end and a lug follower at an opposite end, is pivoted adjacent its midpoint to one edge of the bight portion. Rotation of the door about the first pin, from the closed position to the mid open position, causes the lug follower to move on the body leaf cam edge to a cam-free terminus, in opposed relation to a notch in its associated cam edge. Upon initial rotation of the door about the second pin to its full open position, the cam follower is moved out of a recess in the door leaf cam edge, thereby pivoting the bar so as to move the lug follower into its notch, positively locking the link to the fixed body leaf until the door is returned to its mid open position. Just prior to the door being returned to its mid open position, the cam follower is moved on its cam edge into its recess, causing the bar to rotate the lug follower out of its notch, thereby permitting the link and the door leaf to conjointly pivot about the first pin to the door closed position.
