ABSTRACT:
A trim ring comprises an annulus of metal which is affixed to the rim of an automobile wheel to provide a decorative cover for the wheel rim. Disclosed is a trim ring formed into a collar having the general shape of a pie pan from which the base section or hub is removed. The base section is blanked and drawn to form a number of individual retaining clips. Each clip has a wheel rim engaging retention tab extending therefrom such that when the clips are angularly spaced along the outer periphery of the collar and clinched thereto, the tabs describe a series of retaining members spaced along the collar and coaxial thereto. The tabs have protruding teeth for grippingly engaging the rim of the wheel to secure the trim ring to the wheel rim.
Disclosed also is the method of originally forming the pie pan shape of the collar, blanking and forming the base section to fabricate retaining clips from the blanked circular sheet and affixing the clips to the collar to produce the wheel gripping members.
