Sliding door for motor vehicles

A motor vehicle sliding door can be moved by a sliding movement between open and closed positions, wherein, in order to lock the sliding door in the open position, a mechanical door stop in the form of a locking latch which has a receiving region for a catch element of the sliding door is provided, and wherein the locking latch can be released by a motorized actuation device, whereby the catch element is released. In the event of failure of the motorized actuation device of the locking latch, for an intuitive unlocking and locking of the sliding door in the open position thereof may be achieved in that the locking latch has a resiliently loaded overload lever, in that the overload lever forms a lateral portion of the receiving region of the locking latch and in that, when the locking latch is locked, the overload lever can be pivoted outward when a specific pushing force of the sliding door is exceeded.
