Description
FIELD
[0001] Described herein are modular roof assemblies for vehicles
and particularly modular roof assemblies for vehicles using side
rails to interchangeably mount a variety of hardtop panel
configurations or a convertible soft top canopy.
BACKGROUND
[0002] Vehicles can be configured for various hard top or soft top
convertible roofs. Basic convertible mechanisms can be found in
patent applications and patents such as: DE 197 04 173 C1, DE 199
27 234 C1, DE 199 38 605 C1, DE 199 39 724 C1, DE 199 43 765 C2, DE
10 2004 017 327 B4, DE 10 2004 017 569 B4, DE 102 42 773 B4, and DE
200 06 258 U1, the specifications of which are incorporated herein
by reference.
[0003] Challenges in the art often arise from the extensive (and
expensive) structures often needed for vehicle convertible tops
(both soft tops and hardtops) and their associated mechanisms
(collectively referred to herein as convertible assemblies). In
most instances a customized convertible assembly must be developed
for each vehicle application. As part of that development,
convertible assemblies typically require the vehicle body (e.g.,
BIW or Body in White) to be modified to accommodate the attachment
points of such assemblies to the vehicle, including storage areas
for the roof in a retracted position. BIW refers to the stage in
automotive design or automobile manufacturing in which a car body's
sheet metal components have been welded together, but before moving
parts (doors, hoods, and deck lids as well as fenders) the motor,
chassis sub-assemblies, or trim (glass, seats, upholstery,
electronics, etc.) have been added and before painting. In some
vehicles, an additional complication is that there are no practical
or suitable attachment points or storage areas for the convertible
roof assembly within the vehicle body structure.
[0004] The need for design modifications or accommodations in these
types of applications can significantly add to the overall cost,
time, resources and even weight of the vehicle. Improved design
flexibility, interchangeability and modularity in convertible
assemblies are thus desired.
SUMMARY
[0005] Accordingly, described herein are modular roof assemblies
for vehicles and, particularly, modular roof assemblies for
vehicles using side rails to interchangeably mount a variety of
hardtop panel configurations or a convertible soft top canopy.
[0006] In one approach, a modular roof assembly can have a pair of
side rails configured for attachment to a pair of longitudinal roll
bar members of a vehicle frame by at least one fastener, the side
rails extending in a direction along a length of the vehicle frame
rearward from a wind screen frame of the vehicle frame; the side
rails having at least one inboard guideway to slidably receive
transverse tensioning bows and a track car for a soft top; and the
side rails further adapted to receive at least one hard top
panel.
[0007] In another approach, the modular roof assembly can also
include a rear assembly configured for attachment by an attachment
means from a C-pillar region of the vehicle frame to a D-pillar
region of the vehicle frame. The rear assembly may comprise a
cassette adapted to be seallingly coupled to rearward ends of the
side rails and including a motive force to drive the track car and
tensioning bows along a predetermined travel path within the at
least one guideway.
[0008] In another approach, the soft top is attached to the
tensioning bows providing a weather tight seal for the vehicle roof
when the tensioning bows are in an extended position. The rear
assembly may also have a kinematic to lower a retracted soft top
and rear cassette to a sill of the vehicle frame. The rear cassette
may also have a soft top rear panel having a backlite and/or a soft
top rear panel having a backlite proving a weather tight seal with
a sill of the vehicle frame. In one approach, this weather tight
seal with the sill of the vehicle frame can be an upwardly pivoting
hatch. The modular roof assembly can also include at least one
rigid roof panel, releasably attached to at least the side
rails
[0009] In another approach, a spacing adjustment device is provided
between a first and a second component of a convertible roof
assembly for a vehicle having a body having a first thickness at a
first end and a second, greater thickness, at a second end; an
inner surface configured to conform to an exterior contour of the
first component and an exterior surface opposite the inner surface
and configured to conform to the contours of the second component;
the body having at least two sections each having a different
thickness between the inner and exterior surfaces; wherein the
thickness of the at least two sections increases in step wise
manner from the first end to the second end of the body. The
spacing adjustment device can have at least 4 sections are provided
and each section increases by about 2 mm in thickness relative to a
preceding adjacent section. The interior surface of the spacing
adjustment device can be configured to follow contours of a
longitudinal roll-bar frame member for a vehicle. In another
approach, a mechanism to attach a first component to a second
component is provided having a fastener to adjustably and removably
attach the first component to the second component; the fastener
having a spacing adjustment device between the first and second
component, comprising: a body having a first thickness at a first
end and a second, greater thickness, at a second end; an inner
surface configured to conform to an exterior contour of the first
component and an exterior surface opposite the inner surface and
configured to conform to the contours of the second component; the
body having at least two sections each having a different thickness
between the inner and exterior surfaces; wherein the thickness of
the at least two sections increases in step wise manner from the
first end to the second end of the body. The first component can be
a vehicle body component and the second component can be a
convertible roof assembly component. The vehicle body component can
be an anti-roll bar. The fastener configuration can be
latch/strikers, bolts, glues, sealants, combinations thereof, and
the like.
[0010] In another approach, a modular roof top assembly for a
vehicle can have a vehicle frame having at least one roll bar
member; at least one rail attached to the at least one roll bar
member by a fixing means; and the at least one rail having a
guideway to slidably receive transverse tensioning bows for a soft
top canopy. The fixing means can be at least one matching threaded
nut and a bolt. The orientation of the at least one roll bar member
to the at least one rail can be adjustable by a distance adjustment
spacer provided therebetween. The distance adjustment spacer can be
at least one washer having a bore through which the fixing means
extends.

DETAILED DESCRIPTION
[0039] Advantageously, described herein are modular roof assemblies
for vehicles. In one approach, a soft top convertible assembly is
provided to retract and extend a vehicle soft top canopy using a
guide track disposed within prefabricated rails (e.g., side rails)
and associated mechanisms. The side rails are easily adaptable to a
variety of vehicle body configurations and are easy to install. The
side rail components allow for easy after-market installations.
[0040] The present modular roof assemblies can be configured for
attachment on vehicles where the soft top can be retracted to the
rear of the vehicle, but still forward of the vehicle's CHMSL
(Center High Mount Stop Light, or third brake light) as shown, for
example, in FIGS. 6-7. Components of some modular roof assemblies
described herein may alternately include rigid roof panels to
provide a hard top configuration. The rigid roof panels can be
configured to be easily fastenable to and removable from the side
rails. The side rails according to the present embodiments can be
configured to support soft top configurations, hard top
configurations, or a combination of hard top and soft top
configurations. Where the side rails support both hard and soft top
configurations, the soft top components are preferably removed
prior to installation of any rigid panels.
[0041] It is also noted that the side rails according to the
embodiments described herein can be built into the bodywork of a
vehicle and provided as an OME option. Preferably though, the side
rails are configured for attachment to a vehicle having open
anti-roll bars (cage) for the upper portion of the vehicle frame.
The present embodiments provide flexibility in that they are
attachable to different vehicle configurations and offer several
advantages. Such advantages include easy aftermarket installation
of a complete convertible assembly onto a vehicle having a roll-bar
cage frame.
[0042] Another advantage of the present roof assemblies is that no
vehicle modification or alteration is necessary to install the
present roof assemblies on the vehicle. The present assemblies can
also be easily detached and removed from the vehicle framework and
re-fitted. A further advantage is that a common rear quarter window
panel can be used interchangeably between the soft top and hard top
configurations of the present roof assemblies.
[0043] The components of the present roof assemblies are preferably
designed to permit easy assembly by one individual, and are small
enough to fit through a standard 36 inch door for easy and
convenient storage and transport. The roof assemblies described
herein provide a low profile side view roof system and improved
security (due at least to the absence of zippered components). In
some embodiments, the roof assemblies described herein can include
removable modular components such as side windows, doors, rails,
and even the roof assembly itself may be removed and later again
installed.
[0044] The modular design of the roof assemblies described herein
allow for greater design flexibility in that a design can have a
simplified realization of vehicle body; improved lay-out and
package; reduced number of parts required to provide a convertible
mechanism; improved rigidity and stability of the modular
components of the assemblies; reduction in overall assembly cost;
and overall assembly weight reduction in that the assembly rigidity
is provided primarily by the anti-roll bar or similar framing
structure of the vehicle.
[0045] The preferred embodiments of the roof assemblies described
herein provide a pair of roof side rails (side rails, roof rails),
which are easily attachable (and removable) as an after-market
accessory to predetermined points of vehicle having a roll-cage
(roll-bar) framework. With the side rails installed, modular
components, such as soft top convertible and/or rigid hard-top
panels can then be fastened to the side rails. Optional quick
release latches can allow easy removal of the entire assembly or
individual components of the roof system. Preferred embodiments
illustrate side rails 24 as being mirror images of each other to
orient its track guide assembly 20 inboard towards the vehicles
longitudinal centerline.
[0046] The present side rail structures can also sealingly attach
to the vehicle framework. The side rails can include a mechanism
and rails for the soft-top variant, the attachment elements for the
hard top variant, as well as a sealing assembly for controlling
water between the side rails and the convertible assemblies (both
variants). The side rails can be installed to extend along the
sides of the vehicle either from the windscreen frame, or further
back of the windscreen frame (along the length of the vehicle) to
the rear of the vehicle, or anywhere in between (such as at the top
of the front and possible rear door as well as eventual rear
quarter panel or window).
[0047] Turning now to the figures, for illustrative purposes only,
FIG. 2 shows a vehicle 10 suitable for installation of the present
modular roof assemblies. Again, it is noted that other types of
vehicles having exposed frame components can also be equipped with
the roof assemblies described herein. As shown, vehicle 10 has a
body 12, with a forward door 16 an optional rear door 17, and an
optional rear gate 52 (having rear gate hinges 54 shown, for
example, in FIG. 6).
[0048] As shown in FIG. 2, above a sill 13 of the body 12 of the
vehicle is an exposed roll cage frame 18. This illustrated roll
cage frame 18 has two longitudinal roll bars 19 generally defining
the side of the passenger compartment of the vehicle 10. Roll cage
frame 18 also has cross-bar 48 and cross-bar 50 to add rigidity.
Further strength is added to the roll cage frame 18 by a cross bar
of the windscreen frame 36. Each of the roll bars 19 may attach to
the windscreen frame 36 at point 21 at its forward end, and to the
D Pillar 46 at the aft end 23. It is also noted that longitudinal
roll bars 19 may have OME ("Original Manufacturer Equipment")
attachment points 56 at predetermined points as shown in FIG. 2 to
permit attachment of OME accessories. The attachment points 56 for
the removable side rails described in more detail below are located
along the vehicle length and are positioned along the length of
longitudinal roll-over bars 19. There might be one, two, three, or
more attachment points 56 depending on overall length of the
vehicle 10 and configuration of the side rails. The attachment
points 56, instead of being installed during manufacturing of the
vehicle 10, can be also installed during the installation of the
roof assemblies according to the present embodiments, if
needed.
[0049] As shown in FIG. 3, side rails 24 permit attachment of the
exemplary embodiments of modular roof assemblies to vehicle 10. As
shown in FIGS. 11-12, side rails 24 can have be means such as a
threaded bore 58 (e.g., a nut) configured to receive and fasten
side rails 24 to roll cage frame 18 using fastener 22 (e.g., a
bolt). Threaded bore 58 is oriented to match the corresponding
preconfigured positions of attachment points 56 on roll cage frame
18. In the illustrated preferred embodiment, each of the side rails
24 can be made as a single piece extending along the desired length
(a part of the length or entire length) of the vehicle 10, with the
two side rails 24 on each side of the vehicle 10 being mirror
images of each other. Optionally, one or both of the side rails 24,
instead of having a one-piece construction, can be formed from a
plurality of modular sections, which can be connected in series.
Optionally, attachment elements can also be placed between modular
sections of the side rails 24 to allow hinging of the modular
sections to conform to practically any shape of the vehicle body
12. The modular sections themselves could optionally contain
hingable connections to follow the contours of the respective
longitudinal roll bar 19. Hard top configurations (described in
more detail below) can be configured in separate sections or hinged
together to enable a smaller folded package volume.
[0050] The side rails 24 can be made out of one material or several
materials in various manufacturing and assembly methods. Materials
that may be used to manufacture the side rails 24 can include
metals, composites, extrusions, plastics and various polymers,
combinations thereof, and the like. The present assemblies can also
be configured for placement on vehicles having doors with frames or
frameless doors.
[0051] As shown in FIGS. 2 and 3, longitudinal roll-bars 19 extend
from the A-pillar (post) 40, along to B-pillar 42 and C-pillar 44
to a lower corner of D-pillar 46 on both sides of vehicle body 12
and are connected to each other transversely by cross-bars 48 and
50. The longitudinal roll-over bar 19 is attached to the corners of
windscreen frame 36 of the vehicle 10. Vertical members of roll
cage frame 18 extend down to the vehicle sill 13 of B-pillar 42,
where they are mechanically attached at 43 as shown in FIG. 3. Aft
ends 23 of the longitudinal roll-bars 19 are mechanically attached
to the D-pillar 46 of the vehicle body 12.
[0052] Various attachment members can be employed to fasten the
side rails 24 to roll cage frame 18, such as latch/strikers
combinations, bolts, glues, sealants, combinations thereof, and the
like. Side rails 24 can be attached to roll-cage frame 18 using one
or more fastening means to fasten side rails 24 to roll-cage frame
18 as shown, for example, in FIGS. 11, 12 and 15. The side rails 24
may be attached to the roll-cage frame 18 via a fixed
(non-detachable) attachment or a detachable attachment. The side
rails 24 may be attached directly to longitudinal roll bars 19 (or
similar) structure or indirectly via a separate vehicle part
attached to longitudinal roll bars 19. FIGS. 11, 12 and 15 show
some exemplary attachment mechanisms for attachment of side rails
24 to longitudinal roll bars 19. A weather resistant sealant can
also be disposed between side rail 24 and longitudinal roll bar 19.
FIG. 15 also shows the insertion of a spacer (washer) 25 to provide
a desired spacing between side rail 24 and longitudinal roll bar 19
(distance adjustment member). Such a spacer 25 may be advantageous
to orient the rails 24 per desired design specifications or to
adjust to various vehicle tolerances. It is noted that more than
one spacer may be applied, or even no spacer applied to achieve the
desired positioning of the side rails 24 to the roll cage frame 18.
Alternately, spacer 25 can be selected by its thickness to equal
the spacing needed to achieve the desired positioning of the side
rails 24 to the roll cage frame 18.
[0053] One embodiment of an optional means that may be used to
adjust the desired space between side rails 24 and longitudinal
roll bars 19 is illustrated in FIGS. 11-13. As shown in FIGS.
11-12, a tapered adjustment element 80 may be provided for ease and
efficiency of installation of the side rails 24 onto longitudinal
roll bars 19, especially in the aftermarket, and permits customized
installations, even beyond roll cage design tolerances.
[0054] Adjustment element 80 can be used to set the vertical
orientation of the roll-cage 18 relative to side-rail 24. This
attachment element 80 can be fixed in different orientations via a
fastener 22, so that the distance between the longitudinal roll bar
19 and the side rail 24 can be varied as needed. As shown in FIG.
11 for illustrative purposes, adjustment element 80 is a one
piece-construction that includes a plurality of integral sections
(86a, 86b, 86c, 86d) that provide a series of stepwise increases in
thickness of the adjustment element 80 along the circumference of
adjustment element 80. Specifically, adjustment element 80 can have
its greatest (i.e., maximum) thickness 84 at a first
circumferential end or first section 86a. The stepwise thicknesses
of the adjustment element 80 decreases along sections 86b, 86c
(second and third sections), etc. to the smallest (i.e., minimum)
thickness 82 at a second circumferential end or fourth section 86d.
Although the adjustment element 80 is shown in FIGS. 11-13 as
including four sections 86a, 86b, 86c and 86d that provide a
stepwise increase/decrease in thickness of the adjustment element
80, it will be appreciated that adjustment element 80 includes four
sections each having a different thickness for illustration
purposes only. Namely, adjustment element 80 may be only two
sections, three sections, five sections, or more sections of
varying thickness, whenever necessary to accommodate for side rail
24 and/or roll bar tolerances.
[0055] In one approach each stepwise increase of the adjustment
element 80 can be in the range of about 1-5 mm, preferably in the
range of about 2-3 mm, and more preferably, 2 mm. Maximum thickness
84 of the adjustment element 80 can be in the range of about 5 to
10 mm, and minimum thickness 82 can be in the range of about 2 to 5
mm. During installation of side rail 24 to roll-cage frame 18, the
installer, based on vehicle tolerances, can establish an
appropriate spacing between side rail 24 and roll-cage frame 18,
and install the adjustment element 80 in an appropriate orientation
to provide a desired spacer thickness between the side rail 24 and
longitudinal roll-bar 19 of the roll-cage frame 18 accordingly. As
shown in FIG. 13, the exemplary adjustment element 80 may be
U-shaped and includes a slot 88 between two arm members 81 and 83.
FIGS. 11-12, fastener 22 passes through longitudinal roll bar 19
and can be positioned in the slot 88 and partially surrounded by
arms 81 and 83 of adjustment element 80. When installing the side
rails 24 on longitudinal roll bars 19, the user/installer can
rotate adjustment element 80 until the desired step 86(a, b, c, or
d) equals or nearly equals the desired distance or gap between side
rail 24 and longitudinal roll-bar 19 of roll-cage frame 18, and
then tighten fastener 22 to secure the side rail 24 to the
longitudinal roll-bar 19.
[0056] For permanent installations, adjustment element 80 may be
positioned in the variable gap between the side rails 24 and the
longitudinal roll bars 19 in an orientation that provides an
appropriate thickness (along one of sections 86a, 86b, 86c, or 86d)
before finally attaching the side rail 24 with fastener 22 (e.g.,
bolt) or similar mechanical element that permits a detachable or
non-detachable attachment of side rail 24 to longitudinal roll-bar
19. For example, side rails 24 can be held in desired position
relative to longitudinal roll-bar 19 by assembly brackets welded
onto the roll-bars 19 or by attachment directly (by bolts or
welding) to other parts of the vehicle body.
[0057] During installation of the side rails 24 onto longitudinal
roll-bars 19 of the roll-cage frame 18, the fasteners 22 for the
attachment of the side rails 24 can be initially loosely attached
to longitudinal roll-bar 19 to ease the process. The adjustment
elements 80 may be then slid into the gap between the side rails 24
and the roll-bar frame 18 around the fastener 22. Since the
adjustment elements 80 have several sections (86a, 86b, 86c, 86d)
of different heights (i.e., thicknesses), the adjustment elements
80 are rotated and/or slid into the gap between the side rails 24
and longitudinal roll-bar 19 until a desired location and
orientation of the adjustment elements 80 has been reached and
fastener 22 can be finally fixed into place to secure the side
rails 24 to longitudinal roll-bars 19. This method significantly
reduces the amount of adjustment work, provides a more defined and
robust attachment procedure and provides added security when
assembling the side rails 24 to the roll-cage frame 18 of the
vehicle 10.
[0058] Generally FIGS. 1 and 2-10 show various components to a
convertible assembly 38 having a soft top canopy 14 attached to the
side rails 24.
[0059] FIG. 15 show detail of portions of one side of the
convertible assembly 38 in cross section to illustrate attachment
of various components, including the attachment of the side rail 24
to longitudinal roll bar 19 of the roll cage frame 18. For example,
in FIG. 15, the convertible assembly 38 has a side rail 24 having a
first seal 28 and a second seal 30. First seal 28 can provide a
weather resistant seal between side rail 24 and the convertible
soft top canopy 14. Second seal 30 can provide a weather resistant
seal between side rail 24 and vehicle doors 16 and 17. The seals 28
and 30 may be made of rubber, polymeric, plastic, or other
materials that would provide a seal when installed as shown in FIG.
15. The side rail includes an integrally formed or attached
convertible track guide assembly 20 and a guide member 32 (which is
preferably U-shaped) can be slidably attached to the side rail 24
for travel along the length of the convertible track guide 26.
Guide member 32 can attached to the various soft top framework
components (e.g., cross bow 108) supporting soft top canopy 14.
While the preferred embodiment allows attachment to a roll bar, it
is noted that the present embodiments can also be incorporated into
the body-in-white.
[0060] FIGS. 26-27 show additional detail of the side rail 24 and
vehicle soft top canopy 14 orientation per the sectional view of
FIG. 4. In FIG. 25 seal 28 shows the added detail of water
management channels and the structure of convertible track guide
26. FIG. 26 shows the orientation and structure of convertible
track guide 26 seal 28 continue into drive cassette 124. FIG. 27
shows the orientation of the longitudinal sectional view XXVII of
FIG. 4 where side rail 24 terminates into drive cassette 124 and is
sealed by seal 29.
[0061] As shown in FIGS. 8-10, side rails 24 can be incorporated
into a soft top module 100. Soft top module 100 provides guideways
110 in side rails 104 to extend and retract a convertible roof such
as soft top canopy 14. Soft top module 100 can also be configured
to optionally and additionally accommodate attachment of rigid
panels, as described in more detail below. More specifically, soft
top module 100 provides guideways 110 and 112 to slidably engage
transverse tension bows 106 and 108 respectively. A track car 114
can be provided to facilitate sliding of the bows 106 and 108 along
the length of sliding members or guideways 110 and 112, which may
be in the form of tracks. It is noted that in FIGS. 8-10, a soft
top canopy 14 would be present in actual use, but the soft top
canopy 14 has been removed in FIGS. 8-10 for clarity of the
mechanism underlying the movement of the soft top canopy 14. Side
rails 104 can also have longitudinal soft top canopy material 116
overlying the side rail element.
[0062] As shown, for example, in FIGS. 1, 4 and 8, a preferred
embodiment of the convertible assembly 38 includes a rear cassette
module 124 that can lower the convertible assembly 38 behind the
roll-cage frame 18 (when a user desires to open the roof of the
vehicle 10), but remain in front of a CHMSL of the vehicle 10. In
this instance, the soft top canopy 14 as illustrated remains
inboard of the roll cage frame 18 (FIG. 1). In the preferred
embodiment, the soft top canopy 14 forms a weather (e.g., water and
wind) tight seal along sill 13 of the vehicle 10 as shown in FIG.
4. The convertible assembly 38 also includes a sealing bow 122
where the rearward assembly abuts the vehicle body 12. As shown in
FIGS. 5-7, sealing bow 122 is pivotally mounted to vehicle body 12
to rotate upwards to form an optional hatch 122 which is movable
from a closed position (FIG. 4) to an open position (FIGS. 6 and 7)
to accommodate the storage of various items of cargo 130 in a trunk
of the vehicle 10.
[0063] The convertible assembly 38 may include other optional
components and features. For example, a wiper system can optionally
be included on the backlite 67 (FIG. 4) of the convertible soft top
canopy 14. The soft top canopy 14 may be vertically attached to
cross bows 102, 106 and 108 (shown in FIGS. 8, 9 and 10). As shown
in FIG. 8, cross bow 102 can be a front bar module to connect to
windscreen frame 36. Transverse front cross bow 102 can have a
connection point 118 to the soft top canopy 14. Optionally, the
convertible assembly 38 may include a rear spoiler 150.
[0064] In one preferred embodiment, rear cassette 124 of the
convertible assembly is part of a rear module 120 (FIG. 4) and is
coupled to separate powered motive force to retract soft top canopy
14 along the guideways 110, 112. The rear cassette 124 may be
configured to provide a weather-tight seal via sealing components
installed where rear cassette 124 and soft top canopy 14 engage in
the aft corner of the vehicle 10. Additional and/or alternative
water management and sealing assemblies for the convertible roof
assembly 38 can also be incorporated into the rear cassette 124.
That is, the convertible assembly 38 can provide a weather tight
seal outboard of the roll cage frame 18 of the vehicle 10.
[0065] According to one approach illustrated in FIGS. 16-21, a
modular hard-top assembly 60 according to one exemplary embodiment
is attached to the vehicle body 12 and/or side rails 24 (or quarter
window 72). In the illustrated embodiment, structural support for
the modular hard-top assembly 60 is provided mainly by longitudinal
roll-bars 19 of the roll-cage frame 18. In the embodiment shown in
FIG. 16, the modular hard-top assembly 60 includes a front panel
62, middle panel 64, and rear panel 66 with backlite 67, which can
be opened using backlite hinges 70. The front panel 62 is
preferably attached to the side rails 24, cross-bar 48 and/or
vehicle body 12 by the use of hand operated latches (or other
suitable attachment mechanisms) of the front panel 62 locking onto
strikers in the side rail 24, cross bar 48 and/or vehicle body
12.
[0066] An exemplary attachment of the front panel 62 to the
windscreen frame 36 in cross-section to show more detail is shown
in FIG. 23. As shown in FIGS. 23 and 24, front panel 62 can be
latched to windscreen frame 36 by a front latch 74 mechanism. Front
latch 74 has latch arm 76 pivotally attached front panel 62 at a
latch arm pivot 78 on latch bracket 142. Windscreen 36 has a front
latch striker 75 to engage a front panel 62 latch hook 146 in a
closed position. A weather tight seal is provided by seal 144
attached to windscreen frame 36. Front latch 74 may also have a
user operated handle 148 and a release mechanism 140.
[0067] The middle panel 64 preferably uses the same principle of
attachment to the side rail 24, cross bar 48 and/or vehicle body
12, with the added option of attachment of the middle panel 64 to
the rear panel 66. Rear panel 66 can be attached directly to the
vehicle body 12 using bolts (or other fastening means) along a
lower edge 69 of the rear panel 66 itself with optional additional
attachments to the side rail 24, quarter window 72 and middle panel
64 in a similar manner as described above. Similar to the rear
cassette 124 of the convertible assembly 38 of FIG. 1 described
above, rear panel 66 includes the backlite system, seal interfaces,
vision, hinging, wiring and hoses, BIW interfaces of the hard-top
assembly 60.
[0068] In one preferred embodiment, side rails 24 can also be used
for attachment points of modular roof panels. Thus, side rails 24
can be used not only for providing guide-ways for the cross bows of
a soft-top canopy 14, but also for the attachment of modular
hard-top panels of the hard-top assembly 60 such, as shown in FIGS.
16-21. Thus, the side rails 24 in the exemplary embodiments of
FIGS. 16-21 are provided with guiding channels for the soft top
applications, but also provide for attachment of hard fixed panels
(e.g., 62 and 64) as well.
[0069] In one preferred embodiment, the fixed panels 62 and 64 of
the hard-top assembly 60 can have latches configured to removably
attach at various points along the side rail 24. For example, in
FIG. 16, two hard panels (front panel 62 and rear panel 64), which
may be non-transparent or transparent, are attached. These hard top
panels 62 and 64 preferably have the structure and composition of
typical body panels of the hard-top assembly.
[0070] In the embodiment illustrated in FIG. 17, the hard top
assembly 60 includes a front panel 62a with an optional fixed clear
panel component (e.g., sunroof 63) and a rear panel 64 as in FIG.
16. In the embodiment illustrated in FIG. 18, the hard top assembly
60 includes a front panel 62a with an optional sunroof 63 as well
as rear panel 64a, which has a fixed sunroof 65. In the embodiment
illustrated in FIG. 19, the hard top assembly 60 includes a rear
panel 64a with an optional fixed sunroof 65 while the front panel
62 is the same as the front panel 62 of FIG. 16. In FIG. 20, the
hard top assembly 60 is configured without the front panel 62, but
with a rear panel 64a, which has a fixed sunroof 65. In FIG. 21,
the hard top assembly 60 is configured without the rear panel 62,
but with a front panel 62a, which has a fixed window 63. In FIG.
22, the hard top assembly 60 is configured without the front panel
62 and without the rear panel 64. Preferably, the rear quarter
panel 72 is also independently removable. With a half-door option,
the convertible assemblies (soft-top assembly 38 or hard-top
assembly 60) could be configured as a "flat-top".
[0071] While preferred embodiments have been described in detail,
variations and modifications can be effected within the scope of
the present embodiments.
