  • Patent number: 5801349
    Abstract: A structure for mounting a bracket for a horn pad on a metal core of a steering wheel has a simplified construction. Further, the number of upper contacts is reduced by controlling a movement of the horn pad. The mounting structure and arrangement result in a low cost of production. Generally, the mounting structure includes a plurality of leg parts formed on the metal core of the steering wheel. The leg parts extend generally parallel to a steering shaft. A cross bar is formed on a tip of each leg part. The horn pad's bracket is disposed between the metal core and the cross bars. Biasing devices, for biasing the bracket towards the cross bars are installed between the bracket and the metal core. Positioning devices, for positioning the bracket relative to an axis of the steering shaft are provided on the cross bars and the bracket. The biasing devices are installed at two locations on a lower side of the pad, and at two locations on an upper side of the pad.
