Abstract
A steering column for the steering system of an automotive vehicle has a first steering column member axially movable relative to a second steering column member. The second steering column member is pivotable relative to a vehicle frame. An input shaft connectable with a steering wheel is pivotable relative to the first steering column member. A first tilt locking means locks the second steering column member in a pivot position relative to the vehicle frame. A second tilt locking means locks the input shaft in a pivot position relative to the first steering column member. A telescope locking means locks the first steering column member in an axial position relative to the second steering column member. A locking member has a first position in which the first and second tilt locking means and the telescope locking means are locked. The locking member has a second position in which the first tilt locking means and the telescope locking means are locked and the second tilt locking means is unlocked. The locking member also has a third position in which the first tilt locking means and the telescope locking means are unlocked and the second tilt locking means is locked.
