The invention relates to a linkage flap arrangement of a convertible vehicle having the features of the preamble of claim 1 as well as to a convertible vehicle having such a linkage flap arrangement.
A linkage flap arrangement of the type referred to in the introduction is known from practice and is part of a convertible vehicle that is provided with an adjustable top that can be shifted between a closed position, in which a vehicle interior is covered, and a storage position, in which the vehicle interior is cleared to the top. The top comprises a linkage that presents a link arrangement on each of its two sides in relation to a vertical longitudinal center plane of the top, said link arrangements, in the closed position of the top, reaching through a linkage opening that is disposed in the respective vehicle edge region. In the stored position of the top, in which the top is received by a rear top storage space together with the linkage, the linkage openings are each closed using blinds of a respective linkage flap arrangement. In the closed position, in which the link arrangements reach through the linkage openings, the blinds have to clear the linkage openings. For shifting the blinds between the covering position and the cleared position, drives may be provided. Additionally, several blinds may be assigned to each linkage opening, for covering different parts of the linkage opening. For example, one part is covered by a blind both in the stored position and in the closed position of the top, whereas this part has to be cleared during the shifting movement of the top.
It is the object of the invention to create a linkage flap arrangement that is realized in accordance with the type referred to in the introduction and with which two blinds for covering a linkage opening can be actuated in an optimized manner.
In accordance with the invention, this object is attained through the linkage flap arrangement having the features of claim 1.
In accordance with the invention, a linkage flap arrangement of a convertible vehicle is thus proposed that comprises two blinds that can be driven using a drive means and are coupled to each other via a coupling means in such a manner that a pivoting movement of one blind is converted into a translatory movement of the other blind. One blind can cover a portion of a linkage opening of the relevant vehicle both in the opened position and in the closed position of a linkage, only being transferred into a cleared position during the shifting movement of the top. The other blind covers a second portion of the linkage opening only in the stored position of the top. In the closed position of the top, in which a vehicle interior is covered, this portion of the linkage opening is cleared and the second blind is moved into a stowing position. The two blinds can be controlled in such a way that they are moved downwards when being shifted into a cleared or stowing position, consequently not exhibiting any surface exposed to the wind. This is in particular advantageous when a top is actuated during operation of the relevant vehicle, i.e. when the vehicle is moving. Furthermore, by way of the coupling means, which converts the pivoting movement of the first blind into a translatory movement of the second blind, the motion sequence of the linkage flap arrangement can be performed harmonically.
In a special embodiment of the linkage flap arrangement according to the invention, the first blind is pretensioned in the direction of the storage position using a closing spring. Consequently, the drive means that is actuated using the blind arrangement consisting of the first blind and the second blind only has to act in one direction. A closing movement of the first blind is triggered automatically using the closing spring.
Correspondingly, in an advantageous embodiment of the linkage flap arrangement according to the invention, the second blind is pretensioned in the direction of its covering position using a return spring. The second blind, too, consequently automatically assumes its covering position when being cleared correspondingly.
The coupling means of the linkage flap arrangement according to the invention may comprise at least one coupling link that interacts with a drive link arrangement for the second blind. The coupling link is preferably connected to the first blind or to a support of the first blind and may present ball heads so that a pivoting movement of the first blind may also be effected about an axis that is inclined as compared to a longitudinal vertical plane of the relevant vehicle, i.e. assumes an angle that is smaller than 90°.
The drive link arrangement may comprise a thrust link that interacts, via a driver, with a link unit that is articulated to a slider of the second blind. Consequently, it is possible for the second blind to assume its cleared or stowing position or to be retained in the same, whereas the first blind is pivoted into a covering position, the thrust link then performing a free travel as compared to the link unit.
Preferably, the slider, to which the link unit is articulated for driving the second blind, is guided in a rail that is fixed relative to the car body.
For example, the drive means comprises a Bowden cable that is connected to a support of the first blind that is borne so as to be pivotable. Using the Bowden cable, only a tractive force can be exerted onto the support. The tractive force preferably acts in the direction of the cleared position. When loosening the Bowden cable, the support, and consequently the first blind, is pivoted back into the covering position using the closing spring.
The Bowden cable is preferably driven by a drive that is present at the convertible vehicle in any case. For example, said drive is a drive of a top compartment cover that is moved into an open position when the top is being shifted.
Subject of the invention is also a convertible vehicle that presents a top having a linkage and linkage openings that can each be covered using a linkage flap arrangement of the manner that has previously been described.
Further advantages and advantageous configurations of the subject-matter of the invention can be taken from the drawing, from the description and from the claims.
In the drawing, an exemplary embodiment of a linkage flap arrangement according to the invention is illustrated in a schematically simplified manner and will be explained in more detail in the following description.
In the drawing, a top arrangement 10 of a convertible vehicle, which is not illustrated in more detail otherwise, is illustrated, presenting a folding top 12 that can be shifted between a closed position or a closed-top position, in which a vehicle interior 14 is covered, and a storage position, in which the vehicle interior 14 is cleared to the top. In the storage position, the folding top 12 is received by a rear top storage space 16 of the vehicle, which top storage space can be closed using an adjustable top compartment cover 18.
The folding top 12 comprises a linkage 20 that comprises a link arrangement 22 on each of its two sides in relation to a vertical longitudinal center plane of the top, said link arrangement being borne so as to be pivotable at a respective main bearing 24 that is fixed relative to the vehicle or to the car body. A front bow 26, several transverse bows 28 as well as a rear tensioning bracket 30 extend between the link arrangements 22 that are disposed on each of the two sides, said rear tensioning bracket forming the rear edge of the top in the closed position that is illustrated in
Additionally, a rear window 32, via rear window links, is borne at the link arrangements 22 that are disposed on each of the two sides. The linkage 20 serves to span a top cloth 34 that is produced from a foldable weatherproof material.
The linkage 20 or the two link arrangements 22 of the linkage 20 can each be actuated using an electric motor 42 and be shifted between the closed-top position and the storage position.
The top compartment cover 18 is borne at a link arrangement 36 on each of its two sides in relation to the vertical longitudinal center plane of the top, said link arrangements being borne so as to be pivotable at a bearing 38 that is fixed relative to the car body and being configured to be actuated using a drive motor 40 so that the top compartment cover 18 can be shifted between the closed position illustrated in
In order to make it possible that the link arrangements 22 protrude from the top storage space 16, at the upper side of a vehicle paneling 44, in a region that abuts upon the top compartment cover 18, a linkage opening 46 is realized on each of the two sides in relation to the vertical longitudinal center plane of the top, said linkage opening being configured to be closed, in the storage position of the top, using a blind arrangement 48 that comprises two blinds 50 and 52. As it can be taken from
The blind arrangements 48 are each part of a linkage flap arrangement 54 for the respective link arrangement 22. The linkage flap arrangements 54 that are disposed on each of the two sides are, like the link arrangements 22 of the linkage 20 that are disposed on each of the two sides, realized in a mirror-symmetrical fashion with respect to each other, which is why, in the following description, reference is only made to the linkage flap arrangement that is disposed on the left in relation to the forward direction of travel of the relevant vehicle. The linkage flap arrangement that is disposed on the right in relation to the forward direction of travel of the vehicle is realized in a mirror-symmetrical fashion so that its construction inevitably results along the same lines.
The linkage flap arrangements 54, for the blind 50 that is disposed inside in relation to the vertical longitudinal center plane of the top, in each instance present a blind support 56 that has a support pedestal 58 and a support rod 60. The support pedestal 58 is borne so as to be pivotable at a support bearing 62 that is realized at the main bearing 24 in a fashion fixed relative to the car body, namely about an axis that points backwards and diagonally to the outside in relation to the orientation of the vehicle.
Consequently, the blind 50, upon a pivoting of the blind support 56, also performs a pivoting movement about said axis that is oblique in the vehicle.
A pull cable 64 is linked to the support pedestal 58 of the blind support 56, said pull cable being part of a Bowden cable and being guided, in a Bowden cable guide 66, towards a drive wheel 68 that is a part of the drive for the top compartment cover 18 and is driven by the drive motor 40. Consequently, the linkage flap arrangement 54 is driven using the drive means for the top compartment cover 18.
The blind 50 can be shifted, using the blind support 56, between a covering position that is illustrated in
In order to be able to realize an actuation or a shifting of the blind 52 also using the drive of the top compartment cover 18, a coupling means is provided between blind 50 and blind 52. The coupling means comprises an adjusting lever 72 that is connected to the support pedestal 58 in a rotationally fixed fashion and whose pivot axis is the same as the pivot axis of the blind support 56. A coupling link 76 is articulated to the adjusting lever 72 via a ball-and-socket joint 74, said coupling link interacting with a drive link arrangement for the blind 52, hereunto being connected, via a ball-and-socket joint 78, to a thrust link 80 of the drive link arrangement, said thrust link being pivotable about an axis Y. At the thrust link 80, a driver 82 is realized at the end region that faces away from the ball-and-socket joint 78, said driver acting on a link 84 that is also pivotable about the axis Y and is connected, in an upper end region, via a hinge 86, to another link 88 that is articulated to a slider 90 at its end that faces away from the hinge 86, said slider being part of a support of the blind 52. The slider 90 is guided in an outer rail 92 that is fixed relative to the vehicle. Additionally, the support for the blind 52 comprises two other sliders 94 and 96 that are guided in rails 98 and 100 that are fixed relative to the car body.
The link 84 of the link unit that consists of the two links 84 and 88, at its end that faces away from the hinge 86, is connected to a return spring 102 that pretensions the blind 52 in the direction of its covering position that is illustrated in
The linkage flap arrangement 54 that has previously been described in the drawing works in the manner that is described in the following.
Starting from the covering position of the two blinds 50 and 52 that is illustrated in
If the folding top 12 is now supposed to be moved back into its storage position, the top compartment cover 18 is opened (cf.
