  • Patent number: 6904777
    Abstract: A steering column ignition lock for a motorcycle comprises a lock housing, a closing cylinder, which can be rotated in the lock housing, and closing pins which can be moved in the closing cylinder and can be activated with a key, so that the closing cylinder can be rotated optionally relative to the lock housing or is blocked against rotation. To enable a remote control of the steering column ignition lock, a sleeve is installed rotatably within the lock housing, and the closing cylinder is inserted rotatably within the sleeve. The closing pins can be made to engage with said sleeve so as to block rotation of the cylinder relative to the sleeve. A locking bolt that can be slid in the lock housing can be made to engage with a slotted opening of the sleeve, preventing its rotation relative to the lock housing. The locking bolt has an electromagnet, which can be activated with a remote controller to cause it to disengage with the slotted opening of the sleeve.
