  • Patent number: 4171149
    Abstract: This invention pertains to an improved light duty retention clip particularly suited for use in retaining automotive wheel covers, trim rings, and the like. The invention employs structure which provide an improved two point attachment to the wheel trim. The outer attachment comprises a flange at the clips' outer edge over which the outer edge of the wheel trim may be crimped, and the inner edge of the clip has a pair of integrally formed fingers which wrap around and grip an inner edge forming part of trim, thereby affording a two-point attachment. The clip also has a resilient biting member extending radially outward between the pair of gripping fingers for engaging the axial flange portion of a wheel rim to retain the wheel trim thereon. An embossed protrusion on the clip may be provided to give the resilient biting member stiffness and to aid in dispersing the retention forces over the entire surface area of the clip.
