FOLDING TOP FOR A VEHICLE

Abstract

A folding top for a vehicle includes a folding top fabric for covering a vehicle interior in a closed position and opening up the vehicle interior in an open position. The folding top has an A pillar portion for mechanical connection to an A pillar of the vehicle, a C pillar portion for mechanical connection to a C pillar of the vehicle, a B pillar portion between the A pillar portion and the C pillar portion for lateral connection to a B pillar of the vehicle. A tensioning cable extends from the A pillar portion via the B pillar portion into the C pillar portion on each side of the folding top fabric in order to tension the folding top fabric in the closed position.

[0029] Further advantages, features and details of the invention emerge from the description below in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description may here be essential to the invention in each case individually by themselves or in any desired combination. In the drawings, schematically:

[0031] FIG. 2 shows the mechanical brace located therebelow of the embodiment of FIG. 1,

[0032] FIG. 3 shows an embodiment of a fabric pocket according to aspects of the invention,

[0033] FIG. 4 shows an embodiment of a vehicle according to aspects of the invention, and

[0034] FIG. 5 shows a detailed illustration of a folding top according to the embodiment of FIG. 4.

DETAILED DESCRIPTION OF THE INVENTION

[0035] FIGS. 1 and 2 show a folding top 10 in the closed position SP. In the closed position SP, the folding top 10 comprising the folding top fabric 20 is stretched. FIG. 2 shows the basic brace or a mechanical lever system which is capable of being able to move the folding top fabric 20 to and fro between the closed position SP illustrated and an open position, not illustrated. This should therefore be understood as folding into the open position and unfolding and tensioning into the closed position SP.

[0036] In the closed position SP, as has been illustrated in FIGS. 1 and 2, the mechanical lever system according to FIG. 4 therefore shows an unfolded state. This means that a front mechanical coupling device 70 is arranged in the region of the A pillar portion 30. In this embodiment, said front mechanical coupling device 70 serves to ensure mechanical coupling and therefore latching to a corresponding A pillar 130 of a vehicle 100. A tensioning bow 82 is formed here on the rear mechanical coupling device 80. Said rear mechanical coupling device 80 also serves for mechanical latching in a corresponding C pillar 150 of the vehicle 100.

[0037] In order now to ensure that the folding top fabric 20 of the folding top 10 has a high degree of tensioning and a high freedom from folds in the entire region, in particular in the A pillar portion 30, in the B pillar portion 40 and also in the C pillar portion 50, according to the present invention a tensioning cable 60 is formed here on both sides, illustrated on the left-hand side of the folding top 10. Said tensioning cable 60 extends from the A pillar portion 30 through the B pillar portion 40 as far as the C pillar portion 50. For this purpose, the tensioning cable 60 is mechanically fastened in the region of the front mechanical coupling device 70 and in the region of the rear mechanical coupling device 80, in particular in the region of the tensioning bow 82.

[0038] As can likewise be seen, in the case of the mechanical lever system according to FIG. 2, the B pillar portion 40 is equipped with a window guide 42. In the closed position SP, the tensioning cable 60 encloses an acute angle with said window guide 42 in order thereby to obtain the freedom from folds with an even better distribution of tensioning force in the folding top fabric 20.

[0039] FIG. 4 illustrates how a vehicle 100 with such an embodiment of a folding top 10 behaves. In the closed position SP illustrated, it can readily be seen how a side window 120 separates the A pillar 130 from the B pillar 140 of the vehicle. The C pillar 150 is moreover found behind the B pillar 140. A partial region of the folding top fabric 20 of the folding top 10 extends between the B pillar 140 and the C pillar 150. Accordingly, the tensioning cable 60 also extends here into the C pillar portion 50, and therefore the folding top fabric 20 also has the desired tensioning force in the B pillar portion 40 and in the C pillar portion 50.

[0040] FIG. 5 shows a partial illustration of FIG. 4. It can once again readily be seen here how, in this case, the tensioning cable 60 runs in an outer pocket 90 as far as the C pillar portion 50 via the B pillar portion 40. The correlation with the window guide 42 in the B pillar portion 40 can readily also be seen here.

[0041] FIG. 3 shows a partial embodiment illustrating the fabric pocket 90, as can also be gathered, for example, from FIG. 5. The tensioning cable 60 is accommodated in said fabric pocket 90. The accommodating of the tensioning cable 60 provides firstly a defined positioning and secondly guidance of the tensioning cable 60 during the movement between the closed position SP and a corresponding open position of the folding top 10. In order to ensure that, during the folding operation, undesired overtensioning or overstretching of the folding top fabric 20 is prevented, a folding fabric surface 22 is provided here which, as it were as a reserve fabric surface, can enable even complex folding movements and thereby avoids an undesirable overstretching of the folding top fabric 20.

[0042] The above explanation of the embodiments describes the present invention exclusively within the scope of examples. Of course, individual features of the embodiments, if technically expedient, can be freely combined with one another without departing from the scope of the present invention.
