Fitting for an actuating mechanism of a vehicle seat

The gear fitting (1) has at least two axial ring gears (11,28) that move relative to each other forming central gears and at least one axially arranged peripheral carrier pinion (24) between the ring gears. A wedged disc unit has two parts (22,26) acting in different radial directions, which prevent radial play between the carrier pinion and the ring gears in a locked state of the gear fitting. An Independent claim is included for a vehicle seat.
