Abstract

Abstract A dual-action tailgate for a conventional station wagon type vehicle is mounted on the vehicle body for swinging movement into and out of the rear opening thereof about a vertical axis as a door, or about a horizontal axis as a drop-gate, by a biaxial multihinge and by a pair of hinge-latches each of which hingelatches provides a pivotal connection about one of the two axes and is releasable to allow swinging movement of the tailgate about the other of the two axes. The operating arrangement for the tailgate includes a main latch for maintaining the tailgate in a closed position and having a pair of operating levers connected by rigid links to the hinge-latch assemblies for release of the main latch simultaneously with release of either hinge-latch. Blocking means on the operating levers function independently of the condition of the main latch to prevent simultaneous or concurrent release of both hinge-latches by sensing, through the rigid links the condition of the hingelatches.
