ABSTRACT:
A tilt-lock for a tilt-adjustable steering wheel has angular gross and angular fine adjustment capability. A worm gear sector on a housing pivotable with the steering wheel meshes with a worm wheel on a latch plate pivotable on a stationary bracket. When the latch plate is in a latching position the worm wheel meshes with the worm gear sector to capture the angular gross adjusted position of the steering wheel. The worm wheel is rotatable for angular fine adjustment of the steering wheel. When the latch plate is moved to the releasing position, the worm wheel separates from the worm gear sector to release the steering wheel for angular gross adjustment.
