Abstract
The invention provides a locking device for a tilting and telescoping steering column. The locking device provides a single mechanism for substantially preventing movement of the upper steering column jacket relative to the lower steering column jacket and also for preventing tilting movement of the tilt housing relative to the upper steering column jacket. The locking device includes a linking member that extends parallel to the upper steering column jacket. The linking member is pivotally connected to the tilt housing and slidably connected to the lower steering column jacket. A wedge member is positioned between the linking member and the upper steering column jacket adjacent to the lower steering column jacket. The wedge member is rotatable between a locked position and an unlocked position. In the locked position, the wedge member urges the linking member away from the upper steering column jacket in a direction transverse to the upper steering column jacket.
