Electrically actuated steering column mechanism
First Claim
1. An apparatus for positioning a steering wheel of a vehicle in a desired position comprising:
- a steering column including a steering wheel supporting portion for supporting a steering wheel and also including first and second members movable relative to one another to move said steering wheel supporting portion along at least one of a tilting path of movement and a telescoping path of movement; and
a locking device selectively engageable with said first and second members to lock said first and second members with respect to one another and substantially prevent movement along said at least one of said tilting path and said telescoping path, said locking device including an electric motor and a moveable portion wherein said electric motor moves said moveable portion between first and second positions such that said first and second members being locked with respect to one another when said moveable portion is in said first position and being unlocked with respect to one another when said moveable portion is in said second position.

Abstract
An apparatus for positioning a steering wheel of a vehicle in a desired position. The invention includes a steering column having a steering wheel supporting portion for supporting the steering wheel. The steering column also includes first and second members movable relative to one another. The first and second members are moved relative to one another to move the steering wheel supporting portion, and the steering wheel, along either tilting path of movement, or a telescoping path of movement, or both. The invention also includes a locking device that selectively engages the first and second members to lock the first and second members with respect to one another. The locking device substantially prevents movement of the steering wheel supporting portion, and the steering wheel, along the path of movement. The locking device includes an electric motor. The first and second members are locked and unlocked with respect to one another in response to activation of the electric motor.

15. An apparatus for positioning a steering wheel of a vehicle in a desired position comprising:
-
a steering column including a steering wheel supporting portion for supporting a steering wheel and also including first and second members movable relative to one another to move said steering wheel supporting portion along at least one of tilting path of movement or a telescoping path of movement; and
a locking device selectively engageable with said first and second members to lock said first and second members with respect to one another and substantially prevent movement along said at least one of said tilting path or said telescoping path, said locking device including an electric motor wherein said first and second members being locked and unlocked with respect to one another in response to activation of said electric motor, said locking device also including a first shaft engaged for rotation with said electric motor such that said electric motor, in a first mode of operation, rotates said first shaft in a first direction to lock said steering column and, in a second mode of operation, rotates said first shaft in a second direction to unlock said steering column. - View Dependent Claims (16, 17, 18, 19, 20)
