ABSTRACT:
A vehicle steering wheel centering apparatus comprising an electronic or mechanical leveling device for sensing a deviation in the position of the steering wheel from a centered position and a housing mounted to the vehicle steering wheel for supporting the leveling means. A first arm received in the housing has, at its terminal end, a cam rotatable about a first axis. A second arm received in the housing and coaxial with said first arm has, at its terminal end, a cam rotatable about a second axis parallel to said first axis. In the alternative, the cams are fixed but include a sliding surface adapted to contact and slide along the inner surface of a steering wheel rim when inserted thereagainst. The spring biases the first arm so that the terminal end of the first arm is forced away from and in a coaxial direction with the second arm. The apparatus also preferably includes a second spring coupled to the second arm so that the first and second terminal ends are forced directly away from one another.
