A. BACKGROUND

The invention relates generally to devices for fastening objects, and more particularly to a fastener clip assembly for insertion into an engagement structure, such as a vehicle chassis, a hollow substrate, a wall, a plate, or any suitable surface.
A number of devices and fasteners are currently available for fastening panels, such as body panels and automobile interior trim piece panels, to the chassis of a vehicle. As used herein, a body panel refers to, for example, any interior or exterior body panel on a vehicle, a plastic interior trim piece, headliner, or any interior trim piece. Additionally, the panel may be any suitable exterior body panel, such as a fender, bumper, quarter panel, or door panel. The chassis of the vehicle may include any substrate, plate, body panel, structural framework, chassis component or subcomponent, wall, or any suitable object.
These body panels typically are required to attach to the chassis of an automobile with a relatively low level of insertion force while providing a high level of extraction force suitable to maintain attachment of the panel to the chassis. However, these conventional fastener devices instead provide approximately relatively equal levels of insertion and extraction force. Further, conventional fasteners typically do not adequately secure the panel to the vehicle chassis having sheet metal with different curvature or thicknesses throughout. In addition, conventional fasteners are not suitable under a variety of environmental conditions, such as in the presence of vibration at various levels of amplitude and frequency. For example, the fastener device should prevent or minimize the amount of buzzing, rattling, or any other type of noise that may cause attention to the occupants of the vehicle or otherwise weaken the attachment. In addition, conventional fasteners do not adequately accommodate various levels of production tolerances, such as various dimensions amongst, for example, the body panels as well as the vehicle chassis. Thus, conventional fastener devices typically do not adequately fasten to a range of sheet metal thicknesses and do not minimize or eliminate buzzing and rattling and do not sufficiently accommodate variations in production tolerances.
Fastener clips, such as metal spring fasteners, are known for attaching body panels to an automobile chassis. For example, fastener clips are known having a base plate and four stepped arms extending from the base plate. Each stepped arm includes four incremental steps (stair-steps) suitable for engaging a slot in a vehicle chassis with one of the steps on each arm. The incremental steps allow for engagement, however, in only one of the four discrete step positions rather than over a continuous range of engagement positions. Further, each step has a relatively large rise and run so that, once inserted, movement of the fastener clip within the range of a step size may occur, resulting in wear and/or the generation of noise, including buzzing and rattling as a result of vibrations occurring within the vehicle. In addition, the steps typically cut onto each arm during manufacture and require twisting of each wing on the fastener clip in order to engage the slot in the vehicle chassis. As a result, only an edge or a portion of an edge of each of the steps engages the hole in the vehicle slot.
If the sheet metal varies in thickness or if tolerances in production of the slot in the vehicle chassis or in the trim-piece exist, for example, then engagement of one portion of the hole in the chassis with one of the arms may not provide suitable frictional engagement or otherwise result in movement. Further, less than all four of the arms will make engagement with the slot of the vehicle chassis. Twisting of the body panel will be likely more prevalent because less than four contact points are actually made with the slot of the vehicle chassis. As a result, wear, squeaks, rattles, buzzing, corrosion and loss of elasticity and loss of sealing may result, especially after years of vehicle operation and exposure to vibration and other environmental conditions.

C. DETAILED DESCRIPTION

A fastener clip includes first and second feet and a first and second pair of laterally offset legs extending from the first and second feet. At least one first wing extends from the first pair of laterally offset legs. The at least one first wing has an engagement region. At least one second wing extends from the second pair of laterally offset legs. The at least one second wing also has an engagement region. The engagement regions include a depressed portion operable to adapt to variations or movement of a slot. In some embodiments, the fastener clip may be made primarily of metal—such as spring steel, carbon spring steel, full hard stainless steel, etc. In other embodiments, hard plastic material may be used. Other suitable materials may also be used.
The fastener clip may be configured to fit over a carrier. In some embodiments, the carrier may be made from various plastic or rubber compositions. The carrier may be configured to provide additional support to the fastener clip while providing the fastener clip with some give. In some embodiments, the carrier enables the assembly of the clip and the carrier to have more resistance to rattling, buzzing, and general vibration. In some embodiments, the carrier may comprise a top and a bottom seal configured to form a seal with a top and a bottom surface respectively, where the top and the bottom surfaces are the surfaces that are being fastened using the fastener clip.
In some embodiments, the carrier may be made of plastic nylon, polyoxymethylene (POM, also known as acetal), ABS, Polypropylene, rubber materials of various hardness, etc. In some embodiments, the carrier may be injection molded.
In some embodiments, the carrier may be configured to attach to a clip carrier housing (or housing for short) that may be, for example, attached to or be part of a body panel (one of the parts being fastened).
In some embodiments, the fastener clip assembly may have a high level of extraction force, yet the fastener clip may securely and relatively easily facilitate attachment of a body panel, such as an interior or exterior body panel, with the first engagement structure such as the vehicle chassis. The fastener clip may also be suitable for use in heavy-duty applications such as visor mounting, headliners, and pull-handle fasteners. The wings have an engagement region, size, such as a width, length, thickness, and pivot point to provide very high extraction force levels while the insertion force level is relatively low.
Further, the fastener clip may be used with different sheet metal thicknesses and curvatures. For example, a vehicle may have different sheet metal thicknesses at various parts of the vehicle. The range of slot thicknesses varies continuously from a minimum thickness to a maximum thickness. For example, the minimum thickness may be 0.25 mm or less and the maximum thickness may be 6.0 mm or more. The fastener clip is configured to be inserted into the slot defined in a first engagement structure, such as a vehicle chassis. Since the fastener clip is configured to adapt automatically to different sheet metal thicknesses and curvatures, the same fastener clip may be used throughout the vehicle thus eliminating the need for specific fastener clips for specific slot thicknesses.
The engagement portion, along with an optional engagement tab on each wing, permits relatively easy insertion of the fastener clip into a slot formed within the vehicle chassis while providing a relatively high level of extraction force from the vehicle chassis. Assembly of the body panel onto the vehicle chassis requires a relatively low level of insertion force compared to the extraction force, and as a result provides many ergonomic advantages. For example, the relatively low level of insertion force is particularly advantageous for assembly line operators who repetitively insert body panels onto the vehicle chassis. The relatively low level of insertion force required for inserting the body panel into the vehicle chassis may result in fewer injuries to the assembly workers, including injuries related to repetitive stress syndrome. By eliminating conventional screws for fastening to the roof, assembly of the visor and headliner to the roof with the fastener significantly reduces assembly and servicing time and cost. Further, by eliminating multiple fasteners for different sheet metal thicknesses, confusion during assembly is eliminated/reduced since the same type fastener may be used for all slots. Thus, an assembly worker need not worry about selecting the wrong fastener for different slot thicknesses.
The relatively high level of extraction force, characteristic of the fastener clip, securely attaches the body panel, such as an interior trim piece or headliner, to the vehicle chassis such as a roof. Further, the fastener clip continuously adapts to changes in environmental conditions such as vehicle flexing, vibration and thermal expansion. For example, the fastener clip may adapt to changes in thermal expansion, especially due to the differences in thermal expansion rates between dissimilar metals or metal to plastic with respect to the vehicle chassis components and/or between plastic components such as the interior trim panels attached to the metal vehicle chassis. Yet another advantage is that the fastener clip is relatively easy to manufacture using relatively inexpensive manufacturing processes and materials. The use of the fastener clip decreases production costs, increases worker productivity and efficiency and decreases overall vehicle assembly costs. The fastener clip securely attaches any suitable body panel to the vehicle chassis, such that the fastener clip improves reliability both in the short term and in the long term, while further improving vehicle safety and quality.
The fastener clip together with the help of the carrier dampens vibrations and thus eliminates or substantially reduces buzz, squeak, and rattles. The fastener clip and carrier continuously adapt to changes in environmental conditions such as vehicle flexing, vibration and thermal expansion. For example, the fastener clip and carrier may adapt to changes in thermal expansion, especially due to the differences in thermal expansion rates between dissimilar metals with respect to the vehicle chassis components and/or between plastic components such as the interior trim panels attached to the metal vehicle chassis. The fastener clip may also fasten to plastic and/or metal engagement structures. The fastener clip and carrier may be made of anti-corrosive material such as plastic or treated metal to provide long reliable service life.
It should be noted that the same reference numbers in the figures may refer to similar aspects in clip assemblies from one or more different embodiments.

Frangible link 117 may be configured to hold retainer 1100 and carrier 1200 together until the pieces are to be used as part of a fastener clip assembly. The frangible link may be of the same material as the retainer and the carrier, but the frangible may be constructed to be considerably weaker (for example, by being much thinner) and thus easier to break relative to the components that the link is keeping connected.
In some embodiments, frangible link 117 may be designed to break during first assembly.
Retainer 1100 and carrier 1200 may be used as part of a clip assembly to secure a body panel to an automobile chassis, for example.
