Abstract

See full text

An automatic transmission of a motor vehicle is provided that can be in at least one secured state and one unsecured state has a pivotable selector lever for selecting different gears and/or gear selections and has a first blocking mechanism, which can block the pivoting movement of the selector lever. The first blocking mechanism has a displaceable blocking element and a stationary blocking contour for engaging the blocking element and can prevent the selector lever from being pivoted by the blocking element engaging the blocking contour. A second blocking mechanism has a toggle lever, which is in contact with a stop in a stretched-out blocking position and prevents the release of the first blocking mechanism and makes possible the unlocking of the first blocking mechanism in the release position. A release mechanism releases the toggle lever from the stretched-out blocking position. The toggle lever is arranged such that one leg of the toggle lever acts on the blocking element of the first blocking mechanism.
