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 a roller actuator preferably having inner outer members with a lever supported operably in between by a guide feature for movement along a first centerline substantially parallel to the steering shaft. Preferably, cam couplers are located between the outer member and the lever and the inner member and the lever for converting movement of the lever along the centerline to longitudinal movement of a carrier that traverses the centerline.
