A hinge fitting for seats having an adjustable backrest, comprising first and second hinge members adapted to be secured to one side of the seat and backrest, respectively, and connected pivotably to each other. Locking means normally locks the hinge members at different angles to each other, the locking means including first and second locking members normally meshing with each other in a plane, the first locking member being a toothed sector integral with the second hinge member, the second locking member being a toothed member pivoted on actuating means which in turn is pivoted on the first hinge member and adapted to be operated manually by a control lever. Restraining means cooperates with the first hinge member to restrain the locking members therebetween from being at least partly disengaged from each other in a direction perpendicular to the plane in which the locking members mesh with each other.
