  • Patent number: 5704641
    Abstract: A position stopper for an automotive tilt steering column includes an upper clamp connected to the vehicle above the steering column. The upper clamp includes two spaced walls between which a part of the steering column extends. A first structure is secured to a lower portion of the part of the steering column. The walls are formed with vertically extending slots. A bolt passes through the first structure with both ends projected through the respective slots. One of the projected ends of the bolt is externally threaded. An operation lever has a nut secured to the externally threaded end of the bolt. The other projected end of the bolt has a bolt stopper which contacts the wall to suppress rotation of the bolt about its axis. A second structure is secured to the jacket tube. The second structure has at least a portion resiliently interposed between each of the walls of the upper clamp and the jacket tube to suppress play in the steering column relative to the upper clamp.
