An energy absorber may be used with the motor vehicle steering column of a motor vehicle is provided. The steering column includes a tubular mast jacket and a steering shaft. The tubular mast jacket has an upper end and a lower end. The steering shaft is located and rotatable within the mast jacket. Thee mast jacket and steering shaft are centered along a longitudinal center line. The mast jacket further includes an outer jacket with a top line parallel to the center line and located at a top of the mast jacket. The energy absorber includes a sleeve and a lower mounting bracket. The sleeve has a first end and a second end and forms a sleeve bore for receiving the lower end of the mast jacket. The lower mounting bracket is mounted on a body structure of the motor vehicle and defines a lower mounted bracket bore for receiving the second end of the sleeve. The energy absorber further includes a convex anvil located on at the second end of the sleeve, and generally being centered along the top line. A generally J-shaped strap having first and second legs and a concave web therebetween is generally centered along the top line. The concave web bears against the convex anvil. The first leg is coupled to the lower mounting bracket.

A steering lock mechanism having an actuator communicating with a lock bolt is provided allowing for more space in the vicinity where a steering wheel is supported by an upper steering shaft. Additionally, a bolt engaging device is supported adjacent a lower end of the upper steering shaft in a position to engage a lock bolt such that any torque forces transmitted through the bolt engaging device will not cause damage to either the device or other components of the steering column. The actuator is rotated about an axis from a first position to a second position to cause the lock bolt communicating with the actuator to advance towards the lower end of the upper steering shaft from a locked position to an unlocked position, respectively.

The fine increment tilt mechanism for a vehicle steering column includes a steering column support housing and a tilt housing pivotally connected to the support housing for pivotal movement about a tilt axis. A plurality of fixed teeth on the support housing are engaged by a plurality of pivoted shoe teeth on the tilt housing to fix the tilt housing relative to a tilt axis. A shoe release lever includes a wedge that is moved to a position in which the pivoted shoe teeth are held in engagement with the fixed teeth after the tilt housing is pivoted about the tilt axis to a selected position.
