Abstract
An exterior cladding attachment for a motor vehicle includes a main body portion and a plurality of carets integrally formed therewith which extend in an inboard direction. Each of the plurality of carets is adapted to engage an aperture provided in a body side panel of the motor vehicle and is formed to include a base portion and an engagement portion. The engagement portion passes through the associated aperture and has a stop surface for retaining the caret therein. The base portion includes first and second spaced apart sides having a thickness adjacent to the main body portion which is approximately 25% or less than the nominal thickness of the main body portion. To further secure the main body portion to the motor vehicle, the cladding attachment includes an adhesive strip disposed adjacent horizontally extending adjacent a lower edge of the main body portion.

Description
Background of the Invention
1. Technical Field
The present invention generally relates to motor vehicles. More particularly, the present invention relates to an exterior body side cladding attachment for a motor vehicle.
2. Discussion
Motor vehicles with common body panels are frequently offered in various trim packages each having a distinct exterior appearance. The exterior appearance of the vehicle is often enhanced through distinct front and rear facie. Complementing body side cladding attachments are also often attached to the vehicle. For example, a base model of the vehicle may be offered without body side cladding attachments, whereas upgraded models may include different body side cladding attachments, among other ornamental and functional features.
A number of techniques are known in the art for attaching ornamental panels such as cladding members to the body of a motor vehicle. For example, loose mechanical fasteners are frequently employed. In other applications, mechanical fasteners are heat staked to the cladding member and adapted to engage apertures provided in the body side panel or other portion of the motor vehicle. It is also known to employ double-sided adhesive tape for at least partially fastening ornamental panels to motor vehicles.
While known techniques for attaching ornamental panels to motor vehicles, including but not limited to those techniques discussed above, have proven to be successful for certain applications, they are all associated with certain disadvantages. In this regard, some known techniques are labor and/or cost intensive. Other known techniques do not securely attach the ornamental panel with the associated motor vehicle and/or do not provide an adequate fit between the ornamental panel and the motor vehicle.
Summary of the Invention
The general objects of the present invention include eliminating the need for loose fasteners to attach an appearance panel such as a body side cladding attachment to a motor vehicle, streamlining vehicle assembly, and providing an exceptional fit between the appearance panel and the body of the vehicle that is not otherwise achievable with various other known attachment systems. It is a more specific object of the present invention to provide an appearance panel for a motor vehicle which includes a plurality of integrally molded carets which do not cause surface deformations on the appearance side of the cladding member.
In one form, the present invention provides a motor vehicle having a body and an exterior cladding member. The exterior cladding member includes a main body portion and a plurality of integrally molded carets. The body of the vehicle includes a corresponding plurality of slots. Each of the slots is adapted to receive an associated one of the plurality of carets to mount the cladding member to the vehicle. The carets are configured for snapping engagement with the associated slots.
Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from a reading of the subsequent description of the preferred embodiment and the appended claims, taken in conjunction with the accompanying drawings.

Detailed Description of the Preferred Embodiment
Turning first to FIG. 1, an appearance panel constructed in accordance with a preferred embodiment of the present invention is identified at reference numeral 10 and illustrated attached to an motor vehicle 12. In the embodiment shown, the appearance panel is illustrated as a body side cladding attachment 10. It will be understood that the particular appearance panel 10 and motor vehicle 12 shown are exemplary and that the teachings of the present invention are not so limited.
With continued reference to FIG. 1 and additional reference to FIGS. 2-5, the body side cladding attachment or cladding attachment 10 is shown to generally include a main body portion 14 having a first side or inboard side 16 and a second side or appearance side 18. The first side is adapted to be positioned adjacent to a body side panel 20 of the motor vehicle 12. The second side 18 is configured to contribute toward a distinct exterior appearance of the motor vehicle 12. In the exemplary embodiment illustrated, the appearance side 18 of the main body portion 14 includes a pair of longitudinally extending ribs 22 (shown specifically in FIG. 1). However, it will be readily appreciated by those skilled in the art that the particular exterior appearance of the main body portion 14 is strictly a matter of design choice and readily subject to modification.
To provide means for securing the cladding attachment 10 to the body of the vehicle 12, the cladding attachment 10 is shown to preferably include a plurality of carets 24 which extend in an inboard direction. In the exemplary embodiment, the carets 24 are horizontally aligned adjacent to an upper edge of the main body portion 14. Additionally, the carets 24 are integrally formed with the main body portion 14. In the embodiment illustrated, the cladding attachment is shown to preferably include five (5) carets. The particular number of carets 24 employed will be understood to be exemplary. Furthermore, it will be understood that the carets 24 can extend from alternate positions on the main body portion 10.
With particular reference to the enlarged perspective view of FIG. 4 and the cross-sectional view of FIG. 5, each caret is shown to generally include an engagement portion 26 adapted to pass through an associated slot 28 provided in the body side panel 20 and a base portion 30. The engagement portion 26 includes upper and lower spaced apart sides 31 and 32 interconnected by a pair of V-shaped segments 34. The upper and lower sides 31 and 32 outwardly taper as they extend toward the main body portion 14 to a stop surface 36. As the engagement portion 24 is inserted into its associated aperture 28 in the body side panel 20, the V-shaped segments 34 compress, thereby bringing the top and bottom sides 31 and 32 closer together. Upon complete insertion, the V-shaped segments 34 resiliently expand and the stop surfaces 36 abut an inner side 40 of the body side panel 20 to prevent removal.
The base portion 30 is shown to similarly include first and second spaced apart sidewalls 42 and 44 interconnected by the V-shaped segments 34 of the engagement portion 24 which are common thereto. In the embodiment illustrated, the first and second spaced apart sidewalls 42 and 44 have a first thickness adjacent the engagement portion 24 and a second thickness adjacent the main body portion 14. The first thickness is substantially greater than the second thickness. In one application, the thickness of the sidewalls 42 and 44 adjacent the main body portion 14 is less than approximately 25% of the nominal thickness of the main body portion 14 and more preferably, approximately 23% of the nominal thickness of the main body portion 14.
In the preferred embodiment, the main body portion and the carets are unitarily formed of plastic through an injection molded process. Heretofore, the injection molding of panels to include integral carets produced surface deformations on the appearance side of the panel opposite the carets. By reducing the thickness of the first and second spaced sides 42 and 44, surface deformations on the exterior side or appearance side 18 of the body side cladding member 10 are substantially eliminated.
To further provide means for attaching the body side attachment 10 to the motor vehicle 12, the body side attachment 10 is shown to include an adhesive strip 48. In the embodiment illustrated, the adhesive strip 48 horizontally extends adjacent a lower edge of the main body portion 14 and serves to secure a lower portion of the main body portion 14 to the vehicle 12.
While the above description constitutes the preferred embodiment of the invention, it will be appreciated that the invention is susceptible to modification, variation, and change without departing from the proper scope or fair meaning of the accompanying claims.
