<p>A vehicle door lock system employs an internal manually operated means 1 and an externally actuable motor 16 to operate a door locking/unlocking mechanism 10 . A super locking arrangement allows motor 17 to act on a member 8 to decouple the means 1 from the mechanism 10 . When the ignition switch is operated and the door is locked and superlocked, a control arrangement causes an unlocking signal to be repeated until unlocking action is detected. As shown, on detection of ignition action the unlocking signal is sent to motors 16 and 17 until a switch 12 linked to unlock action signals unlocking. When unlocking occurs the member 8 is brought into contact with a member 21 to disable the super locking. In another embodiment (figs 8,9) when ignition action is detected a signal is sent to motor 17 until a switch actuable by member 8 signals the disabling of the super locking.</p> |
