Ignition lock steering column lock assembly

摘要

An ignition lock steering column lock includes a locking unit of the type having a lockbolt, a lockbolt carrier, and a spring-biased carrier pin engageable by a post slidably provided on a rotatable driver. The carrier pin is positioned on a steering column side of the driver. The operational positions of the lock are provided by detents formed on the driver.

主权项

1. A lock device for a vehicle having a steering member for controlling the direction of travel of the vehicle, the lock device comprising:
a steering member receiving aperture configured to receive the steering member and position the lock device in relation to the steering member; a locking unit including a lockbolt selectively extendable from the lock device for engagement with the steering member to prevent its rotation, a carrier movable with the lockbolt, and a carrier pin supported by the carrier and movable from an extended position to a retracted position against a biasing member; a driver operable to rotate about an axis in response to rotation of a key cylinder; and a post coupled to the driver for rotation therewith, the post being axially slidable relative to the driver, the post having a first configuration which axially interferes with the carrier pin when the lockbolt is extended for engagement with the steering member, the post in the first configuration holding the carrier pin in the retracted position against a force of the biasing member without obstructing movement of the carrier and the lockbolt relative to the steering member, the post having a second configuration axially overlapping the extended carrier pin such that the post thereby obstructs the lockbolt from extending for engagement with the steering member, and the post having a third configuration which is axially spaced from the extended carrier pin so as to avoid axial interference and axial overlap with the carrier pin, wherein the carrier pin is positioned on a side of the driver that is proximate the steering member receiving aperture.
