  • Control mechanism for a vehicle ignition lock
    Patent number: 4232538
    Abstract: A mechanical structure for controlling the available linear movement of a vehicle ignition lock mechanism has a tube member coaxial with the vehicle steering column. The tube member has an opening in which is disposed a pin which moves linearly when the ignition lock mechanism is manually operated. The tube is rotated when the vehicle transmission selector is moved whereby the pin has more or less linear travel available in the opening so that the ignition lock mechanism can be moved to the "Start" position when the transmission selector is in "Park" or "Neutral" and to the "Lock" position only when the transmission selector is in "Park".
