Patent ID: 7188903

Claim:
A fitting for a vehicle seat, comprising: (a) first and second fitting parts that are connected to one another by a gear mechanism so that there can be a rolling movement of the second fitting part on the first fitting part, wherein (1) the second fitting part includes an opening, and (2) the first fitting part includes an opening; (b) a driving ring rotatably mounted in the first fitting part and positioned in the opening of the second fitting part, wherein (1) the driving ring at least partially defines an eccentric arranged so that rotation of the driving ring causes the rolling movement of the second fitting part on the first fitting part, (2) the driving ring includes a first transmission profile and an opening, (3) the first transmission profile includes internal teeth; and (c) a rotatably mounted driving bushing that is positioned in both the opening of the driving ring and the opening of the first fitting part, wherein (1) the driving bushing includes a second transmission profile, and an inner surface that extends around an opening of the driving bushing and defines a third transmission profile, (2) the second transmission profile includes external teeth that are mated with the internal teeth of the driving ring in a form-fitting manner so that the driving bushing and the driving ring are connected to one another, and rotation of the driving bushing causes rotation of the driving ring and thereby the rolling movement of the second fitting part on the first fitting part, (3) the driving bushing is distinct from the driving ring, (4) the driving bushing includes a hub, a gradation, and a flange, (5) the gradation extends farther radially outward than the hub, (6) the flange extends farther radially outward than the gradation, and (7) the external teeth are contiguous with, and extend radially outward from, the gradation.
