Thief=proof lock for motor vehicle doors
The lock incorporates a locking pawl (3) and a pivoting transmission lever (8) which can be operated from the inside of the vehicle. It can be placed against the pawl (3) via a coupling plate (7). The coupling plate can be swung into the path of the transmission lever, by a securing lever (9), using a coupling. The coupling consists of a spring (18) which is mounted between the transmission lever (8) and the securing lever (9). The thief-proofing of the lock incorporates a blocking component (30) which can be brought into engagement with one end (20) of the coupling spring (18) so that the coupling between the levers (8,9) is blocked.
