Abstract
An adjustable steering column assembly of a vehicle has a central lock device for selectably locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The lock device has an actuator preferably having an outer member supported operably by a guide feature carried between the outer member and the bracket for movement along a first centerline traverse to the steering shaft. The bracket also supports a lever of the actuator for movement along a second centerline that intersects the first centerline. At least one roller is located in a raceway defined between the outer member and the lever. Because the raceway is angled with respect to both the first and second centerlines, motion of the lever along the second centerline is converted to motion of the second member along the traversing first centerline.
