Description

CABRIOLET VEHICLE WITH AT LEAST THREE SEPARATE ROOF SECTIONS

The invention relates to a convertible vehicle with a rear, a rear window comprehensive roof unit, a first, in the closed roof position with respect to the direction of this roof part at least one subsequent to the upstream roof part with the roof closed in the direction of travel front roof unit according to the preamble of claim 1 and a associated vehicle roof.

It is known convert cabriolet vehicles with a rear • roof unit, a roof part and a front relative thereto relative movable roof unit, in particular in order to bridge vehicles with large interiors and two or more rows of seats in a row, can. Such a vehicle is disclosed in DE 299 24 707 Ul. The rear Dacheihheit can be displaceable relative to the body about a transverse axis so downwards that it is in the stored position substantially horizontally and with the roof closed to the passenger compartment side facing upward. The front roof part is in the open heranschwenkbar to a location in the boundary area between the second roof ^parts' transverse axis to the rear roof unit and is in the open position oppositely oriented to this. A front roof unit is then in the open roof position above the upstream roof part in the same orientation as this. To impart the opening and closing movement, starting from the rear roof unit, also on the upstream roof part and the front roof unit, are provided on each side of the vehicle about vehicle transverse axes against each other pivotable linkage parts, wherein the construction of linkage parts and connecting joints total of a main camp

^■ . ^{• '} . - i - in the body extends into the connecting portions between the upstream roof part and the front roof unit. The joints open during the roof movement at least partially in the manner of parallelograms and for this purpose comprise on each roof section one above the other two parallel links, resulting in the lateral transverse edge area below the arched roof sections a large space requirement for the linkage parts in the vertical direction or at the rear roof unit forward results. This restricts headroom for the occupants. By their opening and closing against each other also the linkage parts and joints are disturbing in the opening in the field of view, and there is a risk of trapping between closing arms of this linkage parts. Furthermore, a considerable amount of panels in the rear roof unit and the upstream roof part must be provided in order to avoid, at least when the roof is closed, that the linkage parts are visible.

The invention is based on the problem of achieving an improvement here.

The invention solves this problem by a convertible vehicle having the features of claim 1 and by a movable vehicle roof having the features of claim 14. With regard to advantageous embodiments of the invention, reference is made to the further claims 2 to 13.

According to the invention for a convertible vehicle of the type mentioned by the at least one of the rear roof unit associated (s) rotatable shaft (s) causes neither for the forward movement of the upstream roof part to the rear roof unit nor for the movement of the front roof unit to the upstream roof part an opening parallelogram is required. The wave (s) of the rear Roof unit serve as Antriebsverrαittler for both relative movements and ensure a tilt-free and fluid movement of the entire roof movement.

It is visually particularly favorable if the shaft (s) at least one component in the direction of travel and an upward component having or have, in particular, to avoid a Hineinragen in the interior, the or each wave parallel to the plane of extension rear roof unit is located.

For a symmetrical optics, and in particular a parallel function similar on both sides of the vehicle, two shafts are provided, which are located essentially parallel next to lateral edges of a rear window.

Advantageously, the shafts may be bent such that they are not linearly extending over the entire height of the rear roof unit, but the torque transmission in the central region by the C-pillars themselves and they have only up and down stub axle, which include their which then do not disturb the passenger compartment.

The cranked drive shafts also allow a wide rear window, the clear width is not restricted by these waves.

Thus, if the first waves in dual function also serve as axes of rotation for C-pillars of the rear roof part lying to the side of a rear window, they can be screwed in during the roof opening and lie above the rear window with the roof open, so that the dimension of the roof pack laid down does not increase downwards is. Since the upstream roof part anyway in a stored position opposite to the rear roof part is oriented and arched, is available for the swiveled C-pillars enough space without the thickness of the stored roof package would have to increase. In particular, the C-pillars can be pivoted into the cavity between counter-curved roof parts. The roof package is significantly narrower compared to fixed C-pillars, which narrows the storage space of the roof and the edge joint of a top compartment lid can move significantly towards the vehicle center, which improves the design options on the vehicle. The Einschwenkbewegung the C-pillars is also possible via rotary axes with little mechanical effort. At the same time the package of stored roof parts is also flatter, whereby the rear of the vehicle can be designed in a visually pleasing, flatter design.

Further, it is advantageous if an upper spatial gear is provided for translating the rotational movement of the first shaft (s) in the movement of the upstream roof part, which drives a movable about several transverse axes linkage for simultaneous movement of both the upstream roof part and the front roof unit. This results in a very quick and structurally simple way of roof movement.

In particular, the upper spatial transmission may include a universal joint located in the boundary region between the rear roof unit and the upstream roof part, which acts on the front roof unit via a coupling member. This coupling member may be a simple coupling rod, so not a parallelogram with two parallel links and the associated risk of jamming. The coupling member may be located just below the upstream Dachteil-.

C DC A T7DI A TT / DCr-CI Oss \ Conveniently, the rotational movement of the shaft (s) in a pivoting movement between the rear roof unit and the upstream roof part and the coupling member in a relative movement between the upstream roof part and the front roof unit translatable. This results in a delay-free movement of all parts.

Depending on the vehicle, the movement of the coupling element can be translated into different folding, pivoting or similar displacement movements in order to be able to cope with different space requirements for the roof laid down. For example, the movement of the front roof unit can be translatable via an upwardly opening and therefore the head freedom not affecting multi-joint as a parallel displacement of the front roof unit against the upstream roof part. A folding down of the front roof unit down may be possible. Likewise, a plurality of front roof units may be provided to achieve a particularly long roof extension.

The entire roof movement can preferably take place at the same time and positively coupled by only one drive, without the need for expensive further control or drive means.

In particular, a reliable and only on pivot connections without the risk of tilting working kinematics, when the rear roof unit is pivotable about its displacement movement about a transverse to the vehicle first axis, the upstream roof part relative to the rear roof part about a second axis lying parallel thereto pivotable is and the waves couple both swivel axes. Further advantages and features of the invention will become apparent from an embodiment of the subject matter of the invention shown schematically in the drawing and described below.

The convertible vehicle 1 according to the invention comprises in the illustrated embodiment a total of three with the roof 2 with respect to the direction of travel F consecutive and separate roof sections 3, 4, 5, namely the rear roof unit 3, which in the vehicle transverse direction middle region 9 a rear window. 6 and laterally outwardly opposite this separate C-pillars 7, as well as this upstream and here a continuous outer surface having upstream roof part 4 and the here also provided with a continuous outer surface front roof unit. 5 The front roof unit 5 and / or the upstream roof part 4 could for example also contain a lifting or sliding roof. Also, several front roof units are possible one behind the other, so that then, for example, four or five roof sections follow each other in total. The convertible vehicle 1 according to the invention can be both a two-seater and, in particular, comprise a larger passenger compartment with two or even more rows of seats one behind the other.

The rear roof unit 3 projects obliquely upwards in the closed position. The roof part 4 is arranged upstream of the rear roof part 3 in the closed position (FIG. 1) and lies substantially horizontally above the passenger compartment, as does the front roof unit 5.

The roof sections 3, 4, 5 are here separated on their outer surfaces and formed essentially of rigid parts, comprise at least rigid frame over which a reference can be stretched partially.

The rear roof unit 3 is divided in the embodiment over its vertical extent and includes except the central region 9 with the rear window 6 at least substantially laterally located next to this and the rear window 6 movable C-pillars 7. These may also include transverse arms or the like, which extend above or below the rear window 6 in the direction of a vertical longitudinal center plane.

The C-pillars 7 are here at the roof opening with respect to the central portion with the rear window 6 of the roof part 3 pivoted about axes of rotation 10, the at least partially simultaneously drive shafts A for .Einschwenken the ^' have upstream roof part 4 with respect to the rear roof part 3 and each have at least one component in the direction of travel F and an upward component with the roof 2 closed. In the embodiment shown here, the axes of rotation 10 are substantially parallel to the plane of extension of the rear roof part 3 and parallel to the lateral edges of the rear window 6, which is not mandatory. In the drawing, the axes of rotation 10 are guided by the C-pillars 7, the line of the drive shafts A is drawn throughout as a theoretical line of action, without having to be formed separately from the axes of rotation 10.

It is also possible, as an alternative to the screw-in C-pillars 7, to make the C-pillars 7 not pivotable separately relative to the central region 9, and nevertheless to provide drive shafts A. In this embodiment, the rear roof unit 3 would have its full width in the stowed position, the drive shafts A would then only the relative movement of the roof sections 3, 4, 5 cause each other without screwing in the C-pillars and not simultaneously fulfill the function of axes of rotation.

For roof opening, the rear roof unit 3 is rearwardly and downwardly displaceable and the upstream roof part 4 can be pivoted to the rear roof unit 3.

The displacement of the rear roof part 3 takes place about a horizontal and transverse to the vehicle 1 first pivot axis 11, which may be stationary relative to the body 12 or displaceable during the opening. The deposition movement can also be a superimposed movement with translational and rotational components on a circular path or other curve. In the exemplary embodiment, the axle 11 is stationary relative to the body 12. The rear Roof unit 3 is connected via a lever 11 extending from the lever 11 with this axis 11 and pivotable about this.

The pivoting of the upstream roof part 4 to the rear roof unit 3 takes place about a second, with this movable upper horizontal pivot axis in the region of the parting line between the roof sections 3 and 4 and can be mediated via the drive shafts A. The pivotal movement of the rear roof unit 3 can be effected by means of two lateral or one central drive (s) 15, which also causes or effects all relative movements of the roof sections 3, 4, 5 against one another. In particular, a single drive 15 at a central main warehouse can be sufficient. The drive 15 can - as here - be moved and primarily cause the pivoting of the rear roof unit 3 about the axis 11.

The front roof unit 5 is parallel to the roof opening 4 displaceable when opening the roof. Alternatively, for example, a displacement of the front roof unit 5 under the roof part 4 or folding down or up may be possible.

To pivot the horizontal first .Schwenkachse 11 when roof opening or closing two _. These are formed in the embodiments as spherical universal joints, which is not mandatory, but is mechanically very simple and reliable in function. The drive shafts A extend, starting from these, parallel to the extent of the rear roof unit 3 obliquely upward and in the uppermost and lowermost region dek- same with the axes of rotation 10 around which the separately pivotable C-pillars 7 are screwed. In doing so, rend the roof opening the C-pillars 7 so pivoted about the axes 10 relative to the central portion 9 that they lie in the open roof position between the Dachteilen.3, 4 and thereby curved in the same direction to the upstream roof part 4 and the front roof unit 5. Since the roof parts 3, 4 are in any case curved in opposite directions to each other in a stowed position, the cavity created therebetween can be used very advantageously for the pivoting C-pillars 7 without any further loss of space.

In the region of the parting line between the roof sections 3 and 4 are upper spherical gear 14, which are fixed to the roof part 4 and this can thereby pivot in relation to the rear roof unit 3 upon rotation of the shafts A. Thus, in the roof opening .The rotational movement of the two drive shafts A on the one hand in a swinging up of the upstream roof part 4 to the rear roof unit ^' 3 about the upper pivot axis and on the other hand simultaneously in a displacement of the front roof unit 5 relative to the upstream roof part 4 by one or more transverse to the vehicle axes 16, 17, 18, 19 translate.

The upper spatial gear 14 controls for this purpose, inter alia, about these transverse axes 16, 17, 18, 19 movable linkage G. The universal joint 14 is for this purpose in such a way arranged on the front roof part 4, that it is the rotation of the force-transmitting shafts A translated into a pivotal movement of a about a transverse axis 20 of the swingable lever 21, the ^■ in turn the coupling member 22, which here lies parallel to the front roof part 4, operated and acts on this on the front roof unit 5. By means of push or pull movement of the coupling member 22 parallel to the roof part 4, the multi-joint M is simultaneously controlled to move the front roof unit 5. Thus, a simultaneous Sequence of roof opening or closing movement ensured.

The entire movable roof 2 can be tested for function before installation in the shell; The modular unit that has been set up in this way can then be delivered to the shell and assembled. ' The invention is also applicable both in vehicles with manually moving roofs and in particular in fully or partially automatic mobility of the roof 2.
