ABSTRACT:
A motor vehicle seat comprises a pivotal hinge fitting having a fixed component connected to a seat portion, a pivotable component connected to a back-rest, a pivot pin connecting the fixed component to the pivoted component, a toothed part rotatably mounted on the pivot pin, and fine-adjustment means on the pivotable component operable to pivot the pivotable component to adjust the angle of the back-rest relative to the seat portion. The pivotal hinge fitting also includes means on the fixed component to limit turning of the toothed part in a direction corresponding to movement of the back-rest away from the seat portion, an inertia pawl mounted on the fixed component and engageable with the toothed part to prevent the movement of the back-rest towards the seat portion, fine-adjustment limit means to prevent movement of the back-rest towards the seat portion by the operation of the fine-adjustment means exceeding a point at which the center of gravity of the back-rest reaches a predetermined angle to a vertical axis extending through the pivot pin of said hinge fitting and a manually-operable pawl-release lever for forcing disengagement of the inertia pawl from the toothed part if necessary.
