1. A motor vehicle latch comprising:
a locking mechanism having a catch and a pawl,
a release lever which is rotatable about an axis of rotation and that is engageable with the pawl to open the locking mechanism,
an electromotive opening drive that includes a motor, and
a handle connected to a flexible connecting means,
wherein:
the locking mechanism is opened by either of the electromotive opening drive acting by the motor on the release lever, or the handle including the connecting means acting manually on the release lever,
the electromotive opening drive engages on the release lever radially on an inside in relation to the axis of rotation of the release lever, and the connecting means engages on the release lever radially on an outside in relation to the axis of rotation of the release lever,
wherein the electromotive opening drive engages on the release lever a first distance from the axis of rotation of the release lever, and the connecting means engages on the release lever a second distance from the axis of rotation, wherein the second distance is larger than the first distance,
the electromotive opening drive has an actuating cam,
the actuating cam engages a recess on the release lever,
the actuating cam interacts with a contour of the recess,
the recess has a front clearance edge spaced from the contour such that the connecting means manually rotates the release lever independent of the actuation cam interacting with the contour, and
the contour is provided on a first edge of the recess and the front clearance edge is provided on a second edge of the recess that is opposite the first edge such that when the connecting means acts manually on the release lever the front clearance edge moves toward the actuating cam until the front clearance edge engages the actuating cam limiting manual action of the release lever.
