[0002] The above-referenced patents and/or patent applications are
hereby incorporated by reference herein in their entirety.
A. BACKGROUND
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.

It should be understood, however, that the drawings and detailed

within the scope of the present invention as defined by the
appended claims.
C. DETAILED DESCRIPTION
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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).
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] FIG. 1 is an exploded view of a first fastener clip
assembly, in accordance with some embodiments.
[0034] In some embodiments, the fastener clip assembly comprises
retainer 1100 and carrier 1200. Carrier 1200 is configured to
engage and secure itself into an opening at the bottom of retainer
1100. In some embodiments, carrier 1200 is configured to disengage
(upon applying a certain amount of force) and reengage retainer
1100 multiple times.
[0035] In some embodiments, retainer 1100 and carrier 1200 are
configured to fasten together top surface 1300 and carrier clip
housing (or housing) 1400. Housing 1400 may be part of an
automobile body panel (housing 1400 may be either attached to or
molded onto the body panel) and surface 1300 may be part of an
automobile frame. Accordingly, the fastener clip assembly may be
configured to fasten a body panel to an automobile
chassis/frame.
[0036] Receiver 1210 on housing 1400 may be configured to receive
carrier 1200 and secure carrier 1200 to housing 1400.
[0037] Retainer 1100 is configured to secure itself to surface 1300
by engaging slot 1250. In some embodiments of typical usage,
retainer 1100 may be configured to remain attached to surface 1300,
and carrier 1200 may be configured to remain attached to housing
1400. In such embodiments, disengagement of the fastener clip
assembly may be accomplished by disengaging retainer 1100 from
carrier 1200.
[0038] In some embodiments, the carrier may comprise a top lip
1110. The top lip 1110 (and optionally a bottom lip) may be
configured to form a seal with a top surface, such as surface 1300
(and optionally a bottom surface). A seal may prevent dirt, water,
etc. from an environment outside of surface 1300 from entering an
environment inside of surface 1300.
[0039] In some embodiments, retainer 1100 and carrier 1200 may be
manufactured with injection molding using materials such as plastic
nylon, polyoxymethylene (POM, also known as acetal), ABS,
Polypropylene, rubber materials of various hardness, etc.
[0040] In some embodiments, various issues may exist when using
metal retainers to engage metal slots, such as the slots in the
chassis of a car. The retention between the metal retainer and the
metal slot may be unpredictable, for example. Other issues may
arise from variances in slot production, the introduction of burrs
during the slot creation that may interfere with engagement,
alternative chassis materials (such as aluminum), etc. Such issues
may introduce excessive variation and inconsistency in the
extraction force required. In some embodiments, at least some of
the issues may be solved by introducing retainer 1100 and carrier
1200 and configure them such that the main engagement and
disengagement of the fastener clip assembly is performed through
retainer 1100 and carrier 1200.
[0041] FIG. 2 is an exploded view of a second fastener clip
assembly, in accordance with some embodiments.
[0042] In alternative embodiments, the fastener clip assembly
comprises retainer 2100 and carrier 2200. Carrier 2200 is

automobile body panel (housing 2400 may be either attached to or
molded onto the body panel) and surface 2300 may be part of an
automobile chassis/frame. Accordingly, the fastener clip assembly
may be configured to fasten a body panel to an automobile
frame.
[0044] Opening 2210 on housing 2400 may be configured to receive
carrier 2200 and secure carrier 2200 to housing 2400.
[0045] Retainer 2100 is configured to secure itself to surface 2300
by engaging slot 2250. In some embodiments of typical usage,
retainer 2100 may be configured to remain attached to surface 2300,
and carrier 2200 may be configured to remain attached to housing
2400. In such embodiments, disengagement of the fastener clip
assembly may be accomplished by disengaging retainer 2100 from
carrier 2200.
[0046] In some embodiments, retainer 2100 and carrier 2200 may be
manufactured with injection molding using materials such as plastic
nylon, polyoxymethylene (POM, also known as acetal), ABS,
Polypropylene, rubber materials of various hardness, etc.
[0047] In some embodiments, various issues may exist when using
metal retainers to engage metal slots, such as the slots in the
chassis of a car. The retention between the metal retainer and the
metal slot may be unpredictable, for example. Other issues may
arise from variances in slot production, the introduction of burrs
during the slot creation that may interfere with engagement,
alternative chassis materials (such as aluminum), etc. Such issues
may introduce excessive variation and inconsistency in the
extraction force required. In some embodiments, at least some of
the issues may be solved by introducing retainer 2100 and carrier
2200 and configure them such that the main engagement and
disengagement of the fastener clip assembly is performed through
retainer 2100 and carrier 2200.
[0048] FIG. 3 is an exploded view of a third fastener clip, in
accordance with some embodiments.
[0049] In some embodiments, the fastener clip assembly comprises
retainer 3100 and carrier 3200. Carrier 3200 is configured to
engage and secure itself into an opening at the bottom of retainer
3100. In some embodiments, carrier 3200 is configured to disengage
(upon applying a certain amount of force) and reengage retainer
3100 multiple times.
[0050] In some embodiments, retainer 3100 and carrier 3200 are
configured to fasten together top surface 3300 and carrier clip
housing (or housing) 3400. Housing 3400 may be part of an
automobile body panel (housing 3400 may be either attached to or
molded onto the body panel) and surface 3300 may be part of an
automobile frame. Accordingly, the fastener clip assembly may be
configured to fasten a body panel to an automobile
chassis/frame.
[0051] Receiver 3210 on housing 3400 may be configured to receive
carrier 3200 and secure carrier 3200 to housing 3400.
[0052] Retainer 3100 is configured to secure itself to surface 3300
by engaging slot 3250. In some embodiments of typical usage,
retainer 3100 may be configured to remain attached to surface 3300,
and carrier 3200 may be configured to remain attached to housing
3400. In such embodiments, disengagement of the fastener clip
assembly may be accomplished by disengaging retainer 3100 from
carrier 3200.
[0053] In some embodiments, retainer 3100 and carrier 3200 may be
manufactured with injection molding using materials such as plastic
nylon, polyoxymethylene (POM, also known as acetal), ABS,
Polypropylene, rubber materials of various hardness, etc.
[0054] In some embodiments, various issues may exist when using
metal retainers to engage metal slots, such as the slots in the
chassis of a car. The retention between the metal retainer and the
metal slot may be unpredictable, for example. Other issues may
arise from variances in slot production, the introduction of burrs
during the slot creation that may interfere with engagement,
alternative chassis materials (such as aluminum), etc. Such issues
may introduce excessive variation and inconsistency in the
extraction force required. In some embodiments, at least some of
the issues may be solved by introducing retainer 3100 and carrier
3200 and configure them such that the main engagement and
disengagement of the fastener clip assembly is performed through
retainer 3100 and carrier 3200.
[0055] FIG. 4 is a exploded view of a fourth fastener clip, in
accordance with some embodiments.
[0056] In some embodiments, the fastener clip assembly comprises
retainer 4100 and carrier 4200. Carrier 4200 is configured to
engage and secure itself into an opening at the bottom of retainer
4100. In some embodiments, carrier 4200 is configured to disengage
(upon applying a certain amount of force) and reengage retainer
4100 multiple times.
[0057] In some embodiments, retainer 4100 and carrier 4200 are
configured to fasten together top surface 4300 and carrier clip
housing (or housing) 4400. Housing 4400 may be part of an
automobile body panel (housing 4400 may be either attached to or
molded onto the body panel) and surface 4300 may be part of an
automobile frame. Accordingly, the fastener clip assembly may be
configured to fasten a body panel to an automobile
chassis/frame.
[0058] Receiver 4210 on housing 4400 may be configured to receive
carrier 4200 and secure carrier 4200 to housing 4400.
[0059] Retainer 4100 is configured to secure itself to surface 4300
by engaging slot 4250. In some embodiments of typical usage,
retainer 4100 may be configured to remain attached to surface 4300,
and carrier 4200 may be configured to remain attached to housing
4400. In such embodiments, disengagement of the fastener clip
assembly may be accomplished by disengaging retainer 4100 from
carrier 4200.
[0060] In some embodiments, retainer 4100 and carrier 4200 may be
manufactured with injection molding using materials such as plastic
nylon, polyoxymethylene (POM, also known as acetal), ABS,
Polypropylene, rubber materials of various hardness, etc.
[0061] In some embodiments, various issues may exist when using
metal retainers to engage metal slots, such as the slots in the
chassis of a car. The retention between the metal retainer and the
metal slot may be unpredictable, for example. Other issues may
arise from variances in slot production, the introduction of burrs
during the slot creation that may interfere with engagement,
alternative chassis materials (such as aluminum), etc. Such issues
may introduce excessive variation and inconsistency in the
extraction force required. In some embodiments, at least some of
the issues may be solved by introducing retainer 4100 and carrier
4200 and configure them such that the main engagement and
disengagement of the fastener clip assembly is performed through
retainer 4100 and carrier 4200.
[0062] FIG. 5 is a perspective view of a retainer and carrier for a
first clip, in accordance with some embodiments.
[0063] Retainer 1100 includes base 120 extending from sidewall 130.
Sidewall 130 extends down from top portion 190. Retainer 1100
includes wings 140; in some embodiments, one on each side of
retainer 1100. Wings 140 may have an engagement region 150, which
is configured to engage a slot in a surface to which retainer 1100
is configured to attach. The top portion 190 may slope down toward
the sides of retainer 1100 such that the retainer may be inserted
more easily into such a slot. It should be noted that retainer
1100, in some embodiments, may include any number of wings.
[0064] The wings 140 have a size, such as a width, length,
thickness and a pivot point 142 to provide very high extraction
force levels while the insertion force level is relatively very
low. Additionally, the width of the wing 140 may be increased to
further increase the strength of the wing and thus increase the
extraction force, as well as increase the size of the engagement
region. Alternatively, the width of the wing may be decreased, or
the wings may have different widths and engagement regions 150 to
achieve any desired insertion force or extraction force. In some

2100 and carrier 2200 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.
[0107] In some embodiments, frangible link 217 may be designed to
break during first assembly.
[0108] Retainer 2100 and carrier 2200 may be used as part of a clip
assembly to secure a body panel to an automobile chassis, for
example. Carrier 2200 (or multiple carriers) with retainer 2100
still connected may be first attached to a housing on a body panel.
Then the body panel may be pressed towards corresponding slots made
into the chassis where the body panel is to be attached.
[0109] In some embodiments, during the first assembly between the
body panel and the chassis, the frangible link is designed to break
as it is molded to be weaker than the other pieces. Accordingly, in
one step during the first assembly, the frangible link breaks,
retainer 2100 engages and attaches to the chassis slot, and carrier
2200 engages and attaches to retainer 2100.
