A seat back hinge fitting for a motor vehicle seat having a seat carrier and a seat back. The seat back hinge fitting has a lower arm that is rigidly fixed to the seat carrier, an upper arm that is rigidly fixed to the seat back and a forward tilting hinge for swiftly tilting the seat back forward from a position of normal utilization into a forward tilted position. A bearing hole is provided for in one of the two arms. A bearing is pivotally disposed within said bearing hole. A locking device that normally locks a pivot movement of the bearing within the bearing hole is provided. A release means that disengages the locking device when actuated for the purpose of tilting the seat back forward into the forward tilted position is assigned to the locking device.
