  • Patent number: 5967572
    Abstract: A vehicle door lock control arrangement includes a spring lock and an external actuator which is releasably connected to a release lever on the lock side. The release lever can be pivoted between a rest position and a release position against the force of a first spring to act on a pawl which normally retains the lock in its locked position. A further spring is also provided which prevents the lock from being partially released when it is connected to the external actuator. For this purpose, the further spring normally holds the release lever in the rest position but its connection to the release lever is automatically released during the initial actuation of the release lever.
