Abstract

A motor vehicle locking system for a door or hatch, comprising a locking mechanism with a rotary latch and a pawl for latching the rotary latch, a drive pulley for an electrical opening means, which drive pulley can be rotated in a motorized manner in an operating direction for tripping the locking mechanism, and a return spring for rotating the drive pulley in the direction opposite the operating direction, wherein the drive pulley can be rotated in the operating direction without being influenced by the return spring or at least without spring load. Therefore, higher loads can be moved by the drive pulley.
