<p>A motor-vehicle door latch has an input lever pivotal by an inside door handle about an axis and an output lever connected to the latch mechanism and pivotal about the axis between an actuated position corresponding to a door-unlatched position and an unactuated position corresponding to a latched position. The input lever is formed with a straight slot extending radially of the axis and the output lever is formed with an L-shaped slot having one leg extending generally radially of the axis and alignable with the slot of the input lever and another leg. A wheel can rotate about an axis generally parallel to the lever axis and is formed with an arcuate slot slidably receiving one end of a coupling rod having another end engaged in both of the slots of the levers so that, when the other end is engaged in a coupling position in the one leg offset from the other leg, the two levers are rotationally coupled together by the other end and, when the other end is engaged in a decoupling position of the rod in the other leg, the levers can pivot limitedly relative to each other. A spring bearing on the rod urges it into the coupling position. A drive can rotate the wheel into the off position and thereby pull the rod into the decoupling position and also can rotate the wheel into the on position and thereby free the rod for movement by the spring into the coupling position.</p> |
