ELV Mechanism
A locking lever with its position monitored by a sensor and a locking pin are the main
components of the mechanical part designed to lock or unlock the steering column at the
correct moment. The entire internal kinematic structure is designed such that a mechani-
cal lock (locking lever) keeps the unlocked locking pin in position when no power is
applied to the ELV.
