ABSTRACT:
The hinge mechanism for supporting the back part of a vehicle seat for pivotal movement relative to a base part has first and second hinge arms secured respectively to the back part and base part and interconnected by an eccentric device. The eccentric device is rotatably supported on the first hinge arm and supports eccentrically a shaft integral with the second hinge arm. Rotation of the eccentric device by a handle moves the shaft laterally, and two sets of teeth secured respectively to the hinge arms are thereby moved into or out of mesh. A cam acting between the hinge arms maintains the teeth out of mesh while the back part is in a forward tilted position.
