Definitions

• the invention relates to a cylinder lock, in particular for motor vehicles, with a key channel arranged in a cylinder core and spring-loaded slats, which is coupled by means of an axially disengageable coupling with an output member of the cylinder lock, which actuates a door lock mechanism if the cylinder core is rotated with a responsible key, and if the cylinder core is turned with the wrong key or by force, it is disengaged.
• the kinematic coupling between the cylinder core and the output member of the cylinder lock is interrupted, so that the cylinder core spins freely without actuating the door lock mechanism.
• Such cylinder locks are known, in particular for door locks of motor vehicles, which consist of a housing with a cylinder cavity in which a cage is rotatably and axially displaceably mounted in the manner of an overload clutch, in which a cylinder core with the key channel and the sprung slats is also mounted is.

• Such a construction enables a non-rotatable connection of the cylinder core to the cage at the time when the separating clutch is disengaged and, if necessary, with the relevant key, which removes the non-rotatable connection between the cylinder core and the cage caused by the extended slats
