ABSTRACT OF THE DISCLOSURE An improved inertia sensitive seat hinge mechanism which enables the seat back to be normally folded forwardly to permit access to a motor vehicle rear compartment area which locks when exposed to a predetermined acceleration load. The inertia sensitive actuator is in the form of a generally straight lever which is mounted for rotation to the upper hinge structure. A projecting finger of the inertia sensitive pendulum interacts with a cam surface associated with the lower recliner structure to maintain the inertia device in an engaged position when the seat back is in its rearmost folded position. This positioning improves reliability of the hinge device. The configuration of components according to this invention eliminates the objectionable rearward projection presented by many present seat hinge designs which can interfere with free access to the rear compartment area. The configuration further permits the mounting of an emergency release lever which is located close to the junction between the upper and lower hinge structures, thus simplifying trimming of the seat. The hinge mechanism according to this invention is further extremely simple in configuration and operation.
