Vehicle steering-ignition lock - has stop fixed to key cylinder which contacts lock element to prevent movement unless operated by correct key

摘要

A stop (15), fixed to the key cylinder (3), contacts a lock element (16); the latter preventing further key movement. For removal, the key is subsequently turned slightly towards its in-use position, to effect retraction of the lock element (via 19,20), then returned completely to its removal position. ADVANTAGE - Prevents return of the key (1) to its removal position, until a safety condition has been fulfilled. A simple, easy-to-use key removal safety device.
