ABSTRACT:
For a ratchet mechanism for driving adjustment devices for vehicle seats, in particular motor vehicle seats, with a control lever (4) that can be swivelled back and forth and a ratchet (6) movable by this, which cooperates with a gear ring (3) of a driven gear (1), a gear connection is provided between the control lever (4) and the ratchet (6) which engages the ratchet (6) necessarily with the gear ring (3) in an initial area of the swivelling movement of the control lever (4). Only with further swivelling movement of the control lever (4) does the ratchet (6) move on a track about the rotational axis of the driven gear (1) while positively carrying the same. Also the control lever (4) lifts the ratchet (6) from the gear ring (3) necessarily in the starting area of the isle return stroke movement of the control lever (4).
