Definitions
- the invention relates to a convertible vehicle with at least one flexible front and one rigid rear roof area according to the preamble of claim 1 and according to the preamble of claim 3.
- DE 101 40 232 AI shows a cabriolet vehicle with a rigid rear roof part and a flexible roof area adjoining it in the direction of travel, which comprises a roof covering that is gripped by a plurality of cross bars.
- the crossbars are connected to one another in a known manner via lateral frame parts.
- these frame parts are swiveled against each other around vertical axes.
- several drives arranged on the respective longitudinal sides of the vehicle are used. These have to be synchronized with each other in order to ensure a uniform shortening of the roof area in the opening phase, which is complex.
- the fold-in mechanism of the side frame parts shown is complicated, and additional measures must be taken to avoid uncontrolled folding of the roof covering and its jamming in the joint areas.
- the invention is based on the problem of looking at a convertible vehicle of the type mentioned. lent the opening kinematics to optimize the flexible roof area.
- the invention solves this problem by a cabriolet vehicle with the features of claim 1 and by a cabriolet vehicle with the features of claim 3, which can be implemented individually or in combination with one another.
- Advantageous refinements of the subject matter of the invention result from the further claims 2 and 4 to 11.
- the inventive design according to claim 1 creates a classic folding mechanism in the front roof area which has been known for a long time with completely flexible tops and is therefore easy to handle. Due to the foldability of the side frame parts, there are no synchronization problems, the folded section in each case gets into the position required for the opening, for example, due to its own weight. It is therefore prevented that opposite longitudinal side areas at the roof opening are shifted to the rear at different speeds and the flexible roof area can be inclined.
- Folding takes place particularly advantageously in such a way that a roof tip remains open in the opening position and thus remains curved in the same direction to the rear roof part, under which it can be received. Then the roof the tip fits particularly closely to the rear roof egg L, which results in a minimized pack size of the roof.
- the cover In order to avoid an increased tensile load on the cover, it is particularly helpful if at least one bow located in the rear area of the flexible roof area reaches under the cover n r with the roof closed and detaches itself from the roof opening. Then the folding of the cover can also be optimized in such a way that when the roof is opened, it lies tightly and thus saves space under the rear roof part.
- the folding can be further improved if the cover, apart from on the front roof tip, only on a bow flying between the front frame parts, a bow movable in relation to lateral frame parts and in the vicinity the upper edge of the rear roof part remains firmly attached during the entire roof movement.
- a simplification of the control of the roof movement can be achieved if two different movement mechanisms on the one hand for the displacement of the rear roof area from its closed position into an intermediate position enabling the opening of a cover part under it and on the other hand for the further movement of the entire roof - ts are provided.
- 1 to 10 show a complete sequence of the roof opening in a schematic side view of the central vehicle area, seen from the inside, therein 1 shows the position when the roof is closed with the additionally shown rear cover part, front windshield frame and roof cover, as well as head movement curves of the occupants,
- FIG. 2 is a view similar to FIG. 1 during the upward displacement of the rear roof area with the front roof area still closed
- FIG. 3 shows a view similar to FIG. 2 at the end of the upward displacement of the rear roof area with the front roof area just opening and the cover part already open to release a passage opening for the roof
- FIG. 4 is a view similar to FIG. 3 at the beginning of the second movement phase with opening of the front roof area
- FIG. 5 is a view similar to FIG. 4 with the roof opening progressing
- FIG. 6 shows a similar view to FIG. 5 with the roof opening progressing, for the sake of clarity without a rear cover part and further vehicle lines
- 7 is a view similar to FIG. 6 with the roof opening progressing
- FIG. 8 is a view similar to FIG. 7 with the roof opening progressing
- FIG. 9 is a view similar to FIG. 8 with the roof fully open
- the convertible vehicle 1 according to the invention is shown schematically in the figures in its upper and middle area, which includes the passenger compartment 3. This can be covered by a movable roof 2, which is closed in the illustration according to FIGS. 1 and 10.
- the roof 2 comprises a rigid rear roof area 4, which here is designed as a dome overall and comprises a curved rear window 5, which can be provided with a light- and / or heat-absorbing coating outside of a central viewing area and with its transverse edge 11 to in lateral transverse outer regions of the dome 4 extend can. This enables a particularly good view to the rear.
- the roof 2 further comprises a front roof area 6 which is covered with a cover 7 (only shown in FIGS. 1 and 10).
- a plurality of — here three, for example — are used to tension this cover 7 in the closed position with respect to the direction of travel F and lateral frame parts 8, 9, 10 running in the longitudinal direction of the vehicle.
- the conditions in this regard are the same on both sides of the vehicle.
- the rearmost frame part 8 extends from a window sill line upwards. It is rigidly connected to the rear roof part 4 and therefore movable together with it. With the lateral edge 11 of the rear window 5, the frame part 8 can enclose an upward opening angle. The space between the frame part 8 and the edge 11 of the rear window 5 can be covered.
- the rear roof area 4 is connected to the body 12 via a first movement mechanism 27a.
- This comprises a drive element 13 designed here as a hydraulic cylinder, two links 16, 17 which are pivotally held on a triangular link via the links 14, 15 and which are connected at further links 18, 19 to a lever 20 which acts rigidly on the rear roof area 4.
- the first movement mechanics thus holds a four-bar linkage 14, 15, 18, 19 for shifting the rear roof area 4.
- the wishbone is stationary with respect to the body 12.
- the rear roof part 4 can stand on a cover part D, which is not mandatory.
- the cover part D is part of a tailgate H, which can be opened in two opposite pivoting directions and in one case opens a loading opening for a trunk and in the other case a passage opening for the roof.
- the cover part D in the exemplary embodiment can be pivoted relative to the tailgate H, so that the latter does not have to be pivoted open far and yet a large opening can be released by the relative movement of the cover part D relative to the flap H (FIGS. 3, 12).
- Cross bow 21, 22, 23 The front bow 23 is held between the foremost side frame parts 10, which are also connected to one another via a cross member 24, whereby a roof tip which can be locked on the windshield frame 25 is formed. This remains at least essentially during the entire roof opening. Chen in their original orientation, so that they can fit tightly with the roof 2 open under and on the same curved front edge 26 of the rear roof part 4, thus minimizing the pack size, particularly in height.
- the foremost bow 23 in the direction of travel F is connected to the cover 7, as is the bow 22 movable relative to the side frame parts 9.
- the rear bow 21 held between the frame parts 9 only supports the cover 7 when the roof 2 is closed
- the opening removes the cover 7 from this bow 21.
- the cover 7 is therefore not directly connected to the central frame part 9, but is lifted over the roof 2 to close it, for example with lateral tensioning cables.
- the cover 7 is thus overall connected except on the roof top and the bow 23 connected to the foremost frame parts 10 on the bow 22 which is movable with respect to the lateral frame parts 9 and on the rigid rear roof area 4 on its upper edge 26. It can thus fold freely in the central area, so that the bows 21, 22, 23 can be arranged closely one behind the other when the roof is open (FIG. 9, FIG. 18) and thereby minimize the overall pack size, in particular in length.
- the front roof area 6 is movable via a second movement mechanism 27b, whereby this is connected to the first, rear movement mechanism via a coupling rod 28.
- a movement of the front roof area 6 therefore always also causes a movement of the rear roof area 4, which, however, is not the reverse, as will be explained in detail below.
- the second, front movement mechanism 27b comprises at least one drive element 29, here likewise designed as a hydraulic cylinder.
- This acts on a first four-bar linkage 30 with levers 33, 34 articulated on the body side on joints 31, 32, by means of which the central lateral frame part 9 is held movably.
- the lever 33 is extended in such a way that it also controls a further four-bar linkage 36 via a longitudinal coupling 35.
- This connects the two front frame parts 9, 10 via two levers 37, 38.
- the levers 37, 38 are fixed on the one hand via joints 39, 40 on the middle and on the other hand via joints 41, 42 on the front frame part 10.
- the further bow 22, which is movable relative to the frame part 9 is also held on the longitudinal coupling 35.
- a first movement phase only the rear roof section 4 is moved to open the roof (transition from FIG. 1 to FIG. 2 or from FIG. 10 to FIG. 11).
- the piston of the drive element 13 of the first movement mechanism is retracted, as a result of which the levers 16, 17 pivot up and rearward about their joints 14, 15 and thereby move the lever 20 and thus the entire dome 4 upwards and rearwards.
- the front lever 16 is pivoted beyond the vertical, at the end of the first movement phase the roof part 4 tilts slightly forward, so that the cover 7 is relaxed at its connection at the edge 26 (transition from FIG. 11 to) Fig. 12).
- the front roof area 6 can still remain closed during this movement phase. A load on the cover 7 is avoided.
- the cover part D opens, possibly with the tailgate H.
- the front roof area 6 opens by pushing out the drive member 29 via the second movement mechanism 27b and thereby moves the rear roof part 4 via the coupling rod about its horizontal axes 45, 46 which are transverse to the vehicle 1 and which are in the first Were motionless with.
- the rear drive element 13 remains in its retracted end position and thus represents a pure coupling element.
- the entire front roof area 6 can thus be moved under the rear roof area 4, on the one hand, the entire roof 2 is synchronous and without additional drive or via the coupling 28 Control effort in the stored position within the body 12 can be shifted.
- Each movement mechanism 27a, 27b thus comprises a drive orcjan 13, 29, and the drive member 13 of the first movement mechanism 27a remains unloaded in the second movement phase and only serves as a coupling.
- the invention can therefore be used in particular for vehicles with two or more rows of seats, but also for two-seaters.
- All frame parts 8, 9, 10 of the rear 4 and front roof areas 6 are therefore folded against one another about the horizontal transverse axes 45, 46, 31, 32, 43, 44, 39, 40, 41, 42.
- the roof movement is then compulsory. Synchronization is completely unnecessary; Likewise, the movement phases can run completely sequentially without any overlay.
