Description

The The invention relates to a control drive for a motor vehicle lock according to the Preamble of claim 1.

Of the control drive in question is associated with a motor vehicle lock, the application in all types of closure elements of a motor vehicle place. These include in particular side doors, Rear doors, tailgates, trunk lids or hoods. These Locking elements can basically be designed according to the type of sliding doors.

The known control drive ( DE 102 58 645 A1 ), from which the invention proceeds, is associated with a motor vehicle lock with the closing elements latch and pawl. The latch is in the usual way in an open position, in a main closed position and in a prelocking brought. The pawl has the task to hold the latch in the two closed positions. To release the latch, the pawl can be lifted manually.
