ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to attachment devices and more specifically to an interior trim attachment apparatus for an automotive vehicle.
Traditionally, automotive vehicle interior trim components are attached to sheet metal body panels by screws or barbed Christmas tree fasteners. Screws are problematic during installation on a quickly moving assembly line since the power screw drivers often inadvertently disengage the screw head and irreparably mar the adjacent trim panel or bezel. This leads to poor quality or costly removal and scrappage of the expensive trim panel. Furthermore, insertion of multiple screws is time consuming. Moreover, the installed screws are typically considered to be unattractive and are sometimes hidden by extraneous caps, especially for luxury vehicles. Christmas trees, on the other hand, are more aesthetically pleasing and easy to install but are rarely reusable once removed and are not suitable for withstanding loads within moving parts.
The recent modularization of interior trim systems, such as modular headliners, has allowed for the use of snap together parts which sandwich the headliner trim panels. These modular units have encouraged preassembly of various components prior to shipment and final assembly of the system into the automotive vehicle. This has significantly reduced cost while improving quality and aesthetic design flexibility. Notwithstanding, most of the modular sun visor attachments continue to use some screws either during preassembly or final assembly.
Examples of various conventional quick connect sun visors are disclosed in the following U.S. patents: U.S. Pat. No. 5,544,927 entitled “Twist-In Visor Mount” which issued to Snyder et al. on Aug. 13, 1996; U.S. Pat.

SUMMARY OF THE INVENTION
In accordance with the present invention, the preferred embodiment of an interior trim attachment apparatus for an automotive vehicle includes a fastener and a bezel secured together in a screw free manner by rotating one of the components relative to the other. In a further aspect of the present invention, an interior trim member is sandwiched between the fastener and bezel. In another aspect of the present invention, at least one resilient leg projects from the fastener for engagement with a structural panel of the automotive vehicle. In still another aspect of the present invention, a sun visor is attached to either or both of the fastener and bezel components. A method of assembling the apparatus is also provided.
The interior trim attachment apparatus of the present invention is advantageous over traditional devices since the present invention allows for screw free fastening of the bezel, fastener and sun visor to each other and to the structural vehicle panel. Furthermore, the present invention allows for easy, quick and reusable preassembly and disassembly of the parts to each other and during final assembly to the vehicle. Another advantage is that the present invention reduces parts and labor while improving fastening strength and the aesthetic appearance. The fastening system is entirely hidden to the vehicle occupant. Additional advantages and features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.
