Abstract
A mechanism for adjusting the inclination of the seat backs of seats primarily for motor vehicles. The mechanism comprises two brackets, one connected to the base and the other connected to the seat back of a vehicle seat. Each bracket forms an integral structure and comprises a gear ring of internal teeth, said gear rings having the same diameters, with the number of teeth of the respective gear rings differing in number by a predetermined quantity. One or more gear wheels are movable in a planetary orbit inside the brackets and mesh with the teeth of the latter. Cover plates cover the teeth of said brackets and said gear wheel or wheels and mate with a corresponding recess or a corresponding raised portion, respectively. A shaft comprising the axis of rotation of the gear wheel penetrates the cover plates for making said plates rotative as a unit, with the two brackets being made rotative with respect to each other so that the seat back may be continuously adjusted with regard to the base portion of the seat.
