ABSTRACT:
A two part hinge fitting especially adapted for motor vehicle seats of the type characterized by a fixed hinge member fixedly connected to the seat and a tiltable hinge member fixedly connected to the seat back being articulatedly connected to each other and including releasable locking means comprising a gear sector and a pawl, which upon being released, will permit free tilting of the tiltable hinge member and the seat back connected thereto relative to the fixed hinge member connected to the actual seat portion. The pivot means articulatedly connecting the two hinge members occupies a position away from the rear end of the seat and is biased toward the front end of the seat or toward the uppermost end of the backrest so that a larger radius of the sector gear may be designedly provided for reinforcement of the mechanism than that of previous fittings without any fear that the sector gear of such larger radius will obstruct the passenger when leaving the seat. Non-toothed ends of adjacent gear sector provide for complete tilting forwardly and backwardly of the seat back.
