The invention relates to a convertible vehicle comprising a retractable top according to the preamble of claim 1.
In convertible vehicles comprising a retractable top, in particular, a folding top, the top is stowed before driving with the top open, in a top compartment provided at the rear. In this position, the top is loaded by a holding-down device (DE 198 13 347 A1) that is provided on the top compartment lid and embodied as a shaped plastic part in order to keep away vibrations and unwanted loads from the sensitive roof skin during driving. In this connection, the shaped plastic part is secured by means of a fastening part on the underside of the top compartment lid such that the stationary shaped part can be transferred only by a point-precise simple pivot movement into the contact position and a movement of the top compartment lid that comprises also pushing components would cause disadvantageous friction loads in the area of the surfaces at the holding-down device that rest against one another.
The invention concerns the problem of providing an improved folding top for a convertible vehicle whose holding-down device is adjustable with minimal technical expenditure to a pivot-push movement of the top compartment lid and enables, while gently realizing a connection, a optimal securing of the folded-down top.
Based on a convertible vehicle according to the preamble of claim 1, the invention solves this problem with the features of the characterizing portion of claim 1. With regard to important additional configurations, reference is being had to claims 2 to 12.
The convertible vehicle is provided in accordance with the inventive embodiment with a two-part holding-down device whose counter member that is movably supported on the top compartment lid can be connected to the support part in the folded-down position of the top. The counter member can be supported on the top compartment lid so as to be pivotable and/or pushable such that in a connecting position connected to the support part a pushing movement component, generated by the opening or closing kinematic mechanism in addition to the pivot movement, can be deflected without loading the top and, in this way, the two-part holding-down device can be adjusted with minimal expenditure to the kinematic drive mechanism of a top compartment lid, respectively.
In a pivoting phase that is reached when closing the top compartment lid, the support part that has already been positioned by providing the open position of the folding top is brought into connecting engagement with the counter member such that the latter, upon further movement of the top compartment lid, is guided by the support part and can be pivoted relative to the top compartment lid. With this phase-wise joint movement of the top compartment lid and of the counter member embodied as a pivot support, a functional connection of the components that are movable for top control is achieved with minimal expenditure. In this way, the holding-down device according to the invention can be employed for different automatic drive concepts.
The two-part holding-down device is designed by means of appropriate adjusting possibilities in the area of the counter member such that for different roof configurations an optimal holding-down function with minimal load of the components is achievable. The counter member that is configured as a pivot support can be positioned relative to the support part such that with minimal pressure forces the load on a sensitive roof skin of the stowed top is reduced and vibrations that are introduced by the driving loads into the vehicle are dampened on the top by the holding-down device.
Further details and advantages of the invention result from the following description and the drawings that illustrate one embodiment of the top according to the invention in the form of a folding top in more detail. The drawings show in:

The top compartment lid 8 is pivotably supported on the carbody by means of hinge devices 7 (and 7′, not illustrated in the side views of FIGS. 2 to 5) that are positioned opposed to one another mirror-symmetrically to the longitudinal center plane M of the vehicle, respectively. The top compartment lid 8 cooperates forwardly in the traveling direction of the vehicle with at least one locking device 10 provided in the area of a laterally arranged back bow 9. When moving the top compartment lid 8, a drive device identified generally at 11 in the form of a hydraulic lifting drive acts such that the lowering movement (arrow B), illustrated in an exemplary fashion in
For securing the folding top 2 in the top compartment 6 in its open position, a holding-down device 12 (
In the convertible vehicle according to the invention, the holding-down device 12 is formed by a counter member 13 supported on the top compartment lid 8 and a support part 14 connectable therewith when the top 2 is folded back. The principal illustrations according to
The transition phase from
This movement course shows that the kinematic mechanism of the drive on the top compartment lid 8 is adjusted relative to the counter member 13 movable therewith such that, when carrying out a closing or opening movement (corresponding to the reverse movement course, starting at
The counter member 13 is formed in particular as a pivot support 15 that is pivotably supported on the underside of the top compartment lid 8 about a support axis S; its free end can be placed against the support part 14 that is movable together with the kinematic mechanism (not illustrated) of the top into the top compartment 6 and is secured therein essentially stationarily in the open position. The pivot support 15 resting against the support part 14 is pivotable into the joint holding-down position with the support part 15 (
The pivot support 15 has a shaped profile part 16 that can be moved against the support part 14 and has a support contour that provides a reliably reachable contact area so that in this way with minimal expenditure movement tolerances can be compensated within the multi-member kinematic mechanism of the top. It is also conceivable that in this area the parts resting against one another of the holding-down device 12 form a positive-locking connection (not illustrated) with which the pivot support 15 upon closing of the top compartment lid 8 can be entrained and returned into the vertical position illustrated in
In an expedient embodiment, the pivot support 15 is provided with a return element, not illustrated in detail, for example, a spring that retracts upon closing of the top compartment lid 8 and returns the pivot support 15 from the illustrated contact phase (
The pivot support 15 is secured in the area of a support frame 17 on the top compartment lid 8 wherein in this area an additional receiving part (not illustrated can be provided as a securing means. It is also conceivable that, by means of the pivot support 15 received by movement, the holding-down force (arrow A) is changed and in this way the holding-down device 12 is adjusted specifically relative to the vehicle in regard to the folding properties of the stowed folding top 2.
In the illustrated embodiment of the two-part holding-down device 12, the holding-down device has a support part 14 for the pivot support 15 and a bolt 18 that can also be used particularly as of locking member and is supported as a part of the top closure on a forward transverse frame part 19 of the folding top 2. It is also conceivable in this connection that in place of the locking bolt 18 an additional component is attached on the transverse frame part 19 that is provided only as a support.
In reversing the described movability in the area of the pivot support 15, it is also conceivable that the support part 14 is embodied to be pivotable and/or adjustable and, in this way, an appropriate functional unit for securing the top 2 can be achieved.
