Description
[0001] The invention relates to a retractable roof for vehicles
with the features of the preamble of claim 1.
[0002] Such a retractable roof is known from the state of the art
of DE 39 20 909 A1 on which the present invention is based. In the
case of this retractable roof, a cover panel, which is always
located above the roof skin, can be displaced along lateral guide
rails into the opened or closed position. All of the guide rails
are thus arranged above the roof skin so that when the retractable
roof is closed, the guide rails and the one-piece sliding cover
remain above the roof skin and represent a disruptive element on
the surface of the vehicle roof. In order to achieve an extensively
complete exposure of the roof opening, disadvantages in the form of
drag on the vehicle as well as aesthetic factors must be
accepted.
[0003] For this reason, the present invention is based on the
technical problem of presenting a retractable roof which, in the
opened position, permits as complete an exposure of the roof
opening as possible, but whose adjustment elements, when the
retractable roof is in the closed position, are essentially
non-disruptive. It is preferable that the adjustment elements be
simply constructed and/or ensure a very stable attachment of the
mounted cover panel.
[0004] In accordance with the invention, the above-mentioned
technical problem is solved by means of a retractable roof for
vehicles with the features of claim 1.
[0005] In accordance with the invention, it has been recognized
that the guide rails for guiding the support elements of the cover
panel can also be extended beyond the area of the roof opening
below the roof skin if appropriate openings in the roof skin for
the passage of cover panel support elements are provided. As a
result, the support elements of the cover panel can be guided below
the roof skin, and yet are arranged in a mechanically very
effective manner, i.e. relatively far behind at the associated
cover panel.
[0006] Thus, among other things, the following advantages are
achieved: the retractable cover panel may essentially be slid
completely out of the roof opening, so that the roof opening can be
completely exposed. Also, it is possible to respectively arrange
two cover panel-supporting elements at each longitudinal side of
the cover panel portion, which, are respectively arranged in the
vicinity of the front and rear edge of the cover panel. Thus, it is
possible to secure the cover panel in a very stable manner in the
opened position, particularly in the completely opened position.
The stability of the cover, is thus ensured, even during fast
driving speeds of the vehicle since the cover panel is held at a
total of four places spaced relatively far apart. Moreover, there
is the additional advantage that the guide rails are not arranged
outside the roof skin, so that the aesthetic appearance of the
retractable roof is improved. By means of cover panel-supporting
elements that are adjustable in height, it is also possible to
align at least the one cover panel, while in its closed position,
with the vehicle roof.
[0007] Basically, it is also possible to provide several cover
panels which, preferably halfway, respectively, lock the roof
opening in the closed position and both of which are arranged in
the open position above the fixed roof area. Accordingly, both
cover panels at least partially will overlap.
[0008] In the case of a preferred alternative, two cover panels are
provided. The first cover panel is arranged in the open position
above the fixed roof area. The second cover panel can be guided
along guide rails attached to the vehicle, and, starting from the
closed position, lowered into a position beneath the roof area and
along guide rails attached to the vehicle, moved into the lowered
state below the fixed roof area. In this way, the second cover
panel, in the open position, is at least partially arranged below
the fixed roof area and forms a conventional retractable roof while
the first cover panel in the open position is arranged above the
fixed roof area. This combination, where one part of the cover
panel is displaced above and one part below the roof skin--even
without the openings for the rear cover panel--supporting
elements--is of independent innovative significance.
[0009] By means of the two last-mentioned alternatives which have
at least two cover panels for the complete closing of the roof
opening, it is advantageously achieved that the roof opening in the
vehicle roof may occupy more than 50% of the available surface area
of the vehicle roof. Furthermore, since in the open position both
cover panels can be slid in a preferred way completely out of the
roof opening, a retractable roof is created which opens up a large
portion of the vehicle roof.
[0010] Basically, the invention concerns a roof structure for a
vehicle with a retractable roof in accordance with claim 1, where
the fixed roof area and possibly also the opening for cover
panel-supporting elements is/are a portion of the roof structure of
the vehicle assembly.
[0011] Also, in an additionally preferred way, the fixed roof area
itself, which is essentially mounted by means of the extensions of
the guide rails, is constructed in the form of a separate cover
panel. Preferably, its outer surface is essentially aligned with
the remaining roof skin of the vehicle roof. Due to the
construction as a separate cover panel, advantages with respect to
manufacture and mounting result since the openings arranged above
the extensions of the guide rails can be formed in accordance with
the corresponding size and shape of the separate cover panel. The
cut-out area in the vehicle roof is then correspondingly large and
the retractable roof may then be fitted to the opening. Moreover,
there is the advantage that the separate cover panel, as well as at
least the one movable cover panel, may be constructed in a special
way, for example as a translucent or transparent sunroof cover.
[0012] The above-mentioned components as well as the claimed
components which are described in the embodiment examples and are
to be used in accordance with the invention are not subject to
particular exceptions with respect to size, form, material
selection and technical conception, so that the selection criteria
known in that area of application can find unlimited application.
Additional details, characteristics and advantages of the object of
the invention can be gathered from the subsequent description of
the attached drawing, in which, for example, a preferred embodiment
example of the retractable roof of the invention is shown. In the

[0016] FIG. 4 shows the same retractable roof in the opened
position in vertical cross section along line IV-IV in FIG. 2.
[0017] In the FIGS. 1 to 4, a retractable roof 10 of the invention
for a vehicle with a vehicle roof 11 having a roof opening 12 is
shown. Furthermore, the retractable roof 10 has a first cover panel
1 and a second cover panel 2, which cover panels selectively block
the roof opening 12 or at least partially expose it. Furthermore,
cover panel-supporting elements 20 are provided (FIG. 3, 4) which
are tightly connected with the first cover panel 1. Also, cover
panel supporting elements are provided which are connected with the
second cover panel 2; however, these cover panel-supporting
elements are not shown in the drawing for the sake of clarity since
the development of said cover panel-supporting elements is known in
itself and is not essential to the invention.
[0018] At the two lateral edges 12B and 12C of the roof opening 12,
guide rails 16 are provided in which at least the cover
panel-supporting elements 20 are guided. The guide rails 16 each
have one guide respectively, bar bracket 28, into which
respectively one guide pin 21, 21A, 21B grips which is connected
with the cover panel-supporting element 20, 20A, 20B. The path of
the guide bar bracket 28 and the shape of the guide pin 21 are
shown in detail in the FIGS. 3 and 4. The cover panel 1, in the
closed position of the retractable roof as shown in FIG. 1, is
arranged essentially in the surface provided by the roof skin 14.
In an open position of the retractable roof 10, however, the cover
panel 1 is arranged at least partially above a fixed roof area 3
with a predetermined distance above the roof skin 14. This can be
seen in FIGS. 3 and 4.
[0019] The guide rails 16 have extensions 16A which extend in the
direction T of displacement of the cover panel 1 beyond the rear
edge 12A of the roof opening 12 against which the fixed roof area 3
abuts. The guide rails 16, together with their extensions, are
located essentially below the roof skin 14. The fixed roof area 3
is mounted essentially by the two extensions 16A.
[0020] In the area of the extensions 16A of each guide rail 16, an
aperture 18 is provided in the roof skin 14; the guide rails are an
extension of the lateral edges 12B, 12C of the roof opening.
[0021] Finally, provisions are made wherein at least the rear cover
panel-supporting elements 20A engage, at least in the completely
open position of the retractable roof, the extensions 16A of the
guide rails 16 below the roof skin 14 and extend through the
assigned opening 18, thereby keeping the cover panel 1 positioned
above the roof area 3. For this purpose, at each longitudinal side
of the cover panel 1, rear and front cover panel-supporting
elements 20A and 20B are provided which carry the cover panel 1 at
a distance to each other.
[0022] During the opening and closing of the retractable roof, the
following predetermined sequence results due to the shape of the
guide bar brackets 28 of the guide rails 16, including the
extensions 16A: starting with the closed position shown in FIG. 1,
the guide pins 21A of the cover panel-supporting element 20A, which
is in the rear as viewed in the direction of displacement T, extend
at each longitudinal side of the first cover panel 1 at first along
a section 28A of the guide bar bracket 28 which extends to the
rear, diagonally toward the top. Thus, rearward during the
displacement of the first cover panel, the guide pin 21A of the
cover panel-supporting element 20A is set in upward direction, so
that the rear portion of the first cover panel 1 is lifted upwardly
out of the plane of the roof skin 14. During further displacement
of the first cover panel 1 rearwardly, the guide pin 21A of the
rear cover panel-supporting element 20A extends along the
essentially horizontally extending rear guide bar bracket section
28B. If during further rearward displacement of the first cover
panel 1 the front guide pin 21B of the front cover panel-supporting
element 20B is also moved toward section 28A, where the guide pin
extends along a front section 28C of the guide bar bracket 28, then
the front part of the first cover panel 1 is also lifted. In this
way, the completely lifted first cover panel 1 is essentially
parallel to and spaced at a predetermined distance from the surface
determined by the roof skin 14 of the fixed roof area 3. When the
first cover panel 1 is finally adjusted completely in rearward
direction, then it is located completely above the fixed roof area
3, as shown in FIGS. 2 to 4. In this way, the first cover panel 1
completely exposes the surface of the roof opening 12 it covers
when the retractable roof is closed. At that time, due to the
special shape of the cover panel-supporting elements 20 as well as
of the guide rails 16, including the extensions 16A and the slots
18, it is assured that merely a portion of the cover
panel-supporting elements 20 protrudes upwardly from the surface
which is predetermined by the roof skin 14. The actual guidance,
however, takes place underneath the roof skin 14.
[0023] In the example shown in the drawing, a second cover panel 2
is provided which, during its rearward displacement, is also guided
along the guide rail 16, which is rigidly connected to the vehicle
and the extension 16A and is placed into a position below the fixed
roof area 3. If also the second cover panel 2 has been displaced
completely into its opened position, it then also reveals the
surface of the roof opening 12 which is taken up by it in the
closed position. This is shown in the FIGS. 2 to 4, wherein in FIG.
3 the fixed roof area 3 is shown as broken away toward the left in
order to illustrate more clearly the arrangement of the second
cover panel 2 below the roof area 3.
[0024] The openings 18 for the guide rail 16, 16A, which are formed
at the lateral edges of the fixed roof area 3, may be fundamentally
formed by corresponding recesses in the vehicle roof 11. However,
this embodiment, which is not shown in the drawing, makes great
demands on the manufacture of the vehicle roof, so that the shape
of the fixed roof area 3, described below, is preferred.
[0025] As shown in the FIGS. 1 to 4, the fixed roof area 3 is
preferably in the form of an independent cover panel which is
subsequently tightly connected to the vehicle roof 11, wherein the
roof skin 14 is essentially aligned with the remaining vehicle
roof. In order to secure the roof area 3, which is in the form of a
cover panel, to the vehicle roof 11, attachment elements 26 are
provided wherein in the present example the attachment elements 26
are not fastened directly at the vehicle roof 11, but at each of
the extensions 16A of the guide rails 16. However, since the guide
rails 16 are connected without play to the vehicle roof 11, also
the roof area 3 is thus tightly connected to the vehicle roof 11,
as is shown in FIG. 4.
[0026] The attachment elements 26 have the special form shown in
FIG. 4, which results from the position of the guide bar bracket 28
in the extension 16A of the guide rail 16. The thin cover
panel-supporting elements 20A, 20B, which support the first cover
panel 1 in the opened position of the retractable roof 10 above the
fixed roof area 3, must be movable along the guide bar bracket 28
without meeting any obstacles by means of the attachment elements
26 with the assigned guide pin 21A or 21B. For this reason, the
attachment element 26 has a multiply-offset shape, which, on the
one hand, permits an attachment at the extension 16A with the aid
of screws 30 below the position of the guide bar bracket 28 and, on
the other hand, by means of the attachment element 26, an area
below the opening 18 is exposed and the attachment element 26
finally comes to rest against the roof area 3. In this way, the
separate cover panel (fixed roof area 3) is tightly connected to
the extension 16A, at which point the cover panel-supporting
elements 20A and 20B can simultaneously be moved back and forth
along the guide bar bracket 28 in an unhindered manner.
[0027] The attachment element 26 may be tongue-like so that,
similar to the situation of the cover panel-supporting elements 20A
and 20B, a total of several attachment elements for fastening the
fixed roof area 3 finds application. However, as shown and
preferred thus far, the attachment element 26 may also be
strip-like, so that the attachment element 26 is connected without
play to the roof area (3) essentially across the entire length or
across a portion of the length of the separate cover panel, i.e.,
of the fixed roof area 3. The result is that the attachment element
26 functions below the opening 18 also as a water channel.
[0028] As already described, when the retractable roof 10 is in the
opened position, the second cover panel 2 is located under the
fixed roof area 3. For this purpose, the aforementioned cover
panel-supporting elements are necessary, which in a conventional
way are guided along the guide rail 16 and its extension 16A and
have means for lowering and lifting the cover panel 2 or are
connected therewith. Since, thus far, a conventional embodiment of
a retractable roof is involved, the second cover panel 2 is shown
in FIG. 4 without the respective cover panel-supporting
elements.
[0029] Furthermore, the drive mechanism for adjusting the cover
panels 1 and 2 is not shown in the drawing since the type of the
drive and possible coupling means are not essential to the essence
of the present invention. For this reason, each fundamentally
suitable form of a retractable roof drive mechanism can find
application. In the same way, it is purely a matter of choice
whether the cover panel 2, which can be lowered during the opening
process, is arranged in front of or behind the cover panel 1, which
can be lifted during opening, and is arranged in the closed state
or which of the two cover panels is moved first and which one
second.
[0030] Furthermore, the (first) cover panel 1 assumes the function
of a wind deflector in the shown embodiment when it pivots upwardly
at its rear edge at the beginning of the opening movement.
Moreover, it is possible, following the initial pivoting process of
the first cover panel, to at first slide the second cover panel
rearwardly. In this way, the wind deflector function is maintained
until the front cover panel-supporting elements 20B of the front
cover panel 1 are lifted through the diagonal guide bar bracket
section 28A during rearward displacement.
[0031] As shown in particular in FIG. 4, at least one flexible
sealing strip 24A, respectively, for the closing of each opening 18
is provided, wherein the sealing strip 24A is attached at the
lateral edge of the fixed roof area 3.
[0032] During the opening and closing of the retractable roof 10,
the seal 24 is pushed toward the side by the cover panel-supporting
elements in order to locally expose the opening 28. Similarly, the
opening seal of the (second) cover panel 2 is in the closed state:
the sealing strip 24B used makes it possible for the (first) cover
panel 1, during displacement toward the rear, to move across the
cover panel 2 in the same way across the cover panel 3.
[0033] As shown in particular in the FIGS. 3 and 4, the guide rails
16 and their extensions 16A are constructed in such a way that they
have water channels 22 which extend essentially across the entire
length of the cover panels 1 and 2 as well as of the roof area 3.
In this way, water entering through the lateral openings of all
cover panels 1 to 3 can be collected and guided away. In the
present embodiment example, the separate profiles of the water
channels 22 serve as a basic part of the entire retractable roof 10
with which its attachment at the vehicle roof 11 takes place. The
basic part may also be in the form of a surrounding frame and, if
desired may be constructed to be fitted in place.
