ABSTRACT:
A door lock arrangement for motor vehicles with a closing cylinder arrangement (2) attached to outer sheet metal (1) of the body of a vehicle so as to be accessible from the outside and with a lock mechanism (5) attached in the body to be inaccessible from the outside. On the closing cylinder arrangement (2) there is transfer element (6) which establishes the connection of closing cylinder arrangement (2) to the lock mechanism (5). A corresponding coupling element (7) on the lock mechanism (5) engages the transfer element (6) by form-fit such that rotary motion of transfer element (6) is converted into a corresponding rotary motion of the coupling element (7). To secure against illicit penetration into the interior of the motor vehicle, it is provided that, upon forced removal of closing cylinder arrangement (2), the transfer element (6) is entrained by the closing cylinder arrangement (2) so that the coupling element (7), after forced removal of transfer element (6), is destroyed or otherwise modified such that it can no longer be actuated from the outside for purposes of opening the lock mechanism or such that the forced removal of the closing cylinder arrangement (2) triggers an anti-theft system (alarm system).
