Abstract
A convertible vehicle has a folding top frame (3) with a rear folding top clamping collar (4; 4′; 4″), which is constructed in mirror image fashion to the longitudinal median plane (2) of the vehicle. By being shifted about a main bearing (5) attached to the car body, a folding top (7) can be stowed in or returned from a rear folding top compartment (8). The flexible roof skin (6) has in the rear region particularly a dimensionally stable rear window (9) with an essentially rectangular circumferential contour, which extends above the folding top clamping collar (4; 4′; 4″). Only in the region of the upper transverse side edge (10) as well as of its two longitudinal side edges (11, 12) is the dimensionally stable rear window (9) provided with a connection taking hold of the flexible roof skin (6). A lower transverse side edge (13) of the rear window (9) is supported in the closed position of the folding top (7) directly from above on the folding top clamping collar (4; 4′) in a detachable connecting engagement.
Description
BACKGROUND OF THE INVENTION
The invention relates to a convertible vehicle with a folding top having a rear clamping collar.
In the case of a known convertible vehicle of this type (DE 41 28 115 C1), the folding top has a folding-top cloth, which borders the rear window and, in the region above the folding top clamping collar, extends in a broad fabric strip to the rear window, so that the latter, due to the small dimensions, offers a limited field of vision and has a negative effect on the safety of the users of the vehicle. In the case of a folding top of DE 43 09 607 A1, the adjustable rear window is supported with its lower edge region from inside against the folding top clamping collar, so that an external sealing joint, which tends to become soiled and requires disadvantageously high contacting forces and an expensive control system for the components, is formed in a narrow contacting region.
SUMMARY OF THE INVENTION
The invention is concerned with the problem of creating for a convertible vehicle a rear window, which is integrated in the skin of the roof with little technical effort in such a manner that, in the region of the folding top clamping collar, an enlarged window area makes possible an improved rear vision and a reliable leakproofness.
Pursuant to the invention, this objective is accomplished with a rear window for a convertible vehicle with the distinguishing features of claim
1
. With regard to significant further developments of the inventive convertible vehicle, reference is made to claims
2
to
14
.
In the case of the inventive convertible vehicle, the rear window has a window area, the lower transverse edge of which is pulled down to the folding top clamping collar to such an extent, that this clamping collar, when the folding top is closed, acts as a supporting and closing part. In its upper region, the rear window is integrated into the skin of the roof by a three-sided enclosure in the form of a U-shaped frame and the latter is no longer provided between the lower transverse side edge of the rear window and the folding top clamping collar. With its lower transverse side edge, the rear window lies over a sealing system directly on the folding top clamping collar in a closed position in such a manner that the overlapping achieved therewith shows reliable tightness even if the contacting forces are small.
With this tying of the rear window into the roof skin, an advantageous enlargement of the cut-out in the roof skin, provided for the rear window, is achieved and the vision in the rear region of the vehicle is improved as a whole, so that the safety requirements are fulfilled even in the case of different roof contours and aerodynamically changed folding tops of different types of vehicles.
With regard to significant further details and advantageous developments of the invention, reference is made to the following description and the drawings in which several examples of convertible vehicles with the inventive rear window are explained in greater detail.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1
shows a convertible vehicle, which is labeled
1
as a whole and has a folding top frame
3
(
FIG. 2
) with a rear folding top clamping collar
4
, the folding top frame
3
being constructed in mirror image fashion to the longitudinal median plane
2
of the vehicle. When shifted about a main bearing
5
, which is attached to the car body, the folding top
7
, which has a flexible roof skin
6
, together with the folding top frame
3
can be stowed in a folding top compartment
8
(
FIG. 5
) or returned from this into the closed position. In the rear region of its flexible roof skin
6
, the folding top
7
is provided with a rear window
9
with an essentially rectangular circumferential contour, which extends above the folding top clamping collar
4
and is constructed especially as a solid glass window.
The convertible vehicle, which is constructed pursuant to the invention, has a rear window
9
, which has a connection, which takes hold of the flexible roof skin only in the region of the upper transverse side edge
10
as well as of the two longitudinal side edges
11
and
12
of the rear window, which are parallel to the longitudinal median plane
2
of the vehicle. The rear window
9
is supported with its lower transverse side edge
13
directly on the folding top clamping collar
4
. With that, vision through the rear region of the vehicle is improved in all of the embodiments of
FIGS. 2
to
6
shown, owing to the fact that, with the direct support, components impeding vision are avoided and a vehicle user has a greater field of vision in a vision plane E (FIG.
5
).
To handle this enlarged rear window
9
, the latter has a control assembly
14
, which engages the longitudinal side edges
11
and
12
(of which only one is shown), and is connected with the driving kinematics of the folding top frame
3
, the main bearing
5
and the folding top clamping collar
4
. Directly in the edge region in which the rear window
9
and the roof skin
6
are connected, this control assembly
14
may be hinged in such a manner, that it is subjected during the movement of the folding top to a constrained control due to the folding of the roof skin (not shown).
In the embodiment of the rear window connection of
FIGS. 2
to
6
shown, the rear window
9
in each case has a frame
15
, which embraces it with an upper transverse side leg
32
and parallel longitudinal side legs
33
and
34
and to which the control assembly
14
is hinged. With a connection of this design, the rear window
9
can be shifted under the control of the folding top kinematics. Likewise, it is conceivable that a driving organ, which is not shown, is integrated into the assembly for moving the rear window
9
.
The lower transverse side edge
13
of the rear window
9
can be fixed over its whole width on the folding top clamping collar
4
in a detachable connecting engagement. The views of
FIGS. 2
to
4
illustrate that the lower transverse side edge
13
of the rear window
9
lying in the closed position (
FIG. 2
) of the folding top
7
from above on the folding top clamping collar
4
so as to form a seal, can be shifted relative to the folding top clamping collar
4
and, during the movement of the latter, a distance A is formed at least phase-wise between the transverse side edge
13
and the folding top clamping collar
4
. With the embodiment of the control assembly
14
shown in
FIGS. 2 and 4
, the rear window
9
, starting from its closed position, in which it lies on the folding top clamping collar
4
, is shifted towards the outside (arrow L, FIG.
4
).
In
FIG. 3
, the control assembly
14
is provided with a parallelogram link arrangement having two hinged struts
16
and
17
, so that the rear window
9
, during a first opening phase (arrow B) of the folding to top
7
, is swiveled up together with the folding top clamping collar
4
, these two parts forming the distance A with an expansion position (angle W). The hinged struts
16
and
17
are hinged, on the one hand, to the longitudinal side leg
33
(and
34
, not visible) of the frame
15
and, on the other, a connection is produced with the folding top frame
3
and with the folding top clamping collar
4
.
In the embodiment of
FIGS. 2 and 4
, the control assembly
14
, in the vicinity of the folding top frame
3
, has a swiveling leg
18
, which is provided between the longitudinal side leg
33
of the frame
15
and the folding top clamping collar
4
and interacts over a guiding assembly
19
(instead of the swiveling strut
17
,
FIG. 3
) with the rear window
9
and the folding top clamping collar
4
. With this driving concept, a swiveling and lifting movement, illustrated by arrow C, is imparted to the rear window. The swiveling leg
18
is connected over a guiding strut
18
′ with the folding top frame
3
(FIG.
2
).
In
FIGS. 5 and 6
, the construction, connecting the rear window
9
to the frame
15
, is provided with a folding top clamping collar
4
′, which is constructed in three parts in its longitudinal direction and has two side parts
21
and
22
(not visible), which extend parallel to its middle part
20
. In this embodiment, the lower transverse side edge
13
of the rear window
9
is supported on the middle part
20
, which extends between the side parts
21
and
22
.
The two side parts
21
,
22
are connected with the middle part
20
by a supporting axis
23
, which extends essentially perpendicularly to the longitudinal median plane
2
of the vehicle and, in the rear window
9
in the region of its lower transverse side edge
13
, is firmly connected with the middle part
20
in any manner, the details of which are not shown. In an appropriate embodiment, this firm connection between the rear window
9
and the folding top clamping collar
4
′ is achieved owing to the fact that the U-shaped frame
15
, in region of its side legs
33
(and
34
), is connected terminally in the region of an arched contour
26
with the middle part
20
and the transverse side edge
13
is gripped from below by a seal (not shown).
This type of connecting the rear window
8
to the folding top clamping collar
4
′ of
FIG. 6
also results in improved vision in the plane E. The rear window
9
can be swiveled jointly with the middle part
20
(arrow K, FIG.
5
), so that, when this assembly is stowed in the folding top compartment
8
, the rear window
9
can be swung down as far as the plane of the folding top clamping collar
4
′ and a space-saving, tight, packed position of this folding top
7
is achieved.
In the embodiments of the folding top frame
3
, shown in
FIGS. 2
to
6
, the individual parts of the roof skin
6
, for greater clarity, have been shown in each case by a line of dots and dashes. For an optimum movement and folding of this roof skin
6
, it has turned out to be advisable that, in the region connecting the rear window
9
or externally in the region of the respective longitudinal side legs
33
(and
34
) of the frame
15
, a pocket
31
for the fabric of the folding top (broken line in
FIG. 6
) be provided, which extends in the roof skin
6
to the respective folding top clamping collar
4
,
4
′ or to the side parts
21
,
22
of the latter and acts as a tension compensating zone during the movement of the folding top
7
.
