  • Patent number: 4749234
    Abstract: A wheel trim retention system is disclosed herein which incorporates an anti-rotation clip which is adapted to be secured to the peripheral portion of a wheel trim and to cooperatingly engage portions of a vehicle wheel so as to prevent relative rotation between the wheel trim and the vehicle wheel. The anti-rotation clip comprises first and second portions each of which are adapted to engage and be compressed between generally opposed surfaces of the vehicle wheel whereby the force of engagement of one of these surfaces with the vehicle wheel is increased by the action of the engagement of the other of these surfaces within an opposed portion of the vehicle wheel. The first of these portions includes circumferentially spaced radially outwardly turned end portions which are adapted to engage a radially inwardly facing surface of the vehicle wheel so as to inhibit relative rotation between the trim member and wheel.

  • Patent number: 4723818
    Abstract: A wheel trim assembly is described having an annular wheel trim member which is removably attached to a central hub member by a centrally located fastener or bolt. The central hub member is adapted to attach to an associated wheel. The annular trim member has a central aperture having a removable cover member disposed therein to conceal the centrally located fastener or bolt from casual view. Also disclosed is a locking bolt which has an outer face with a groove therein adapted to receive a corresponding projection of a wrench to effect rotation thereof and which is maintained in aligment by a bolt retainer located in the interior of the trim member. Several arrangements for preventing rotation of the trim member relative to an associated wheel are also disclosed.
