This application claims the priority of German patent document 103 29 439.2, filed Jul. 1, 2003 (PCT International Application No. PCT/EP2004/006951, filed Jun. 26, 2004), the disclosure of which is expressly incorporated by reference herein.
The present invention relates to a hardtop convertible vehicle.
A convertible of the generic type with a hardtop which has three roof parts, is disclosed for example in German patent document DE 101 33 957 A1. In the open roof (top down) position, the front roof part is stowed in the trunk of the vehicle, between the central and the rear roof parts. The front roof part is raised over the central roof part by means of a corresponding lever arrangement during a stowing movement.
German patent document DE 199 62 070 A1 discloses a similar arrangement, in which the front roof part is likewise raised over the central roof part. However, in the stowed state, the front roof part lies at the top.
German patent document DE 196 42 153 A1, on the other hand, describes a motor vehicle with a retractable roof which also has three roof parts. In this case, the front roof part is folded in an articulated manner and is stowed in the trunk between the central roof part and the rear roof part. A similar folding-in of the front roof part is also described in German patent document DE 93 07 481 U1, but with the front roof part coming to lie right at the bottom.
German patent document DE 197 51 660 C1 discloses a device for stowing the roof construction of a hardtop vehicle, which includes a front roof part and a rear roof part. The rear roof part has a rear window that is pivoted relative to the rear roof part by means of a lever and a joint during the stowing movement of the two roof parts and is stowed in an opposed direction to the rear roof part. Rotation of the rear window in such a manner is also known from German patent document DE 198 07 490 C1. However, in the latter case, the rear window is merely rotated through an angle of approx. 15° and is therefore stowed essentially in the same direction as the rear roof part.
Finally, German patent document DE 101 16 709 A1 also discloses the movement of a rear window in relation to the rear roof part. However, in this case the rear roof part has an additional roof segment which likewise has to be pivoted, so that a very complicated construction and a correspondingly complicated stowing movement are required.
In all of the described roof systems with three roof parts, there is the fundamental problem that, in the open (top down) roof position, in which all of the roof parts are located in the trunk, the volume of space available in the trunk is substantially restricted.
It is therefore an object of the present invention to provide a convertible vehicle with a hardtop with at least three roof parts, in which the hardtop requires as little space as possible when stowed in the trunk.
This and other objects and advantages are achieved by the convertible top configuration according to the invention, in which the rear window is articulated in relation to the C-pillars. The resultant pivoting of the same, causes the rear window to assume a position in which it lies with its curvature in the same direction as that of the central roof part, achieving a considerable saving of space in the region between the C-pillars of the rear roof part. Thus, substantially more space is available for luggage when the roof is in the open (top down) position.
The volume of available trunk space in the open roof position is further increased by the fact that the front roof part is stowed in a very efficient manner, either along a backrest or along a motor vehicle tank, rather than with the rear and the central roof parts one above another. The result is therefore a convertible which provides its passengers with sufficient luggage space, even in the open state of the roof.
A particular advantage of the invention can be seen in its comparatively simple construction with a correspondingly uncomplicated configuration of the components.
Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.
The hardtop 2 is illustrated in two positions in
The roof parts 3, 4 and 5 are connected to one another in an articulated manner, and thus movement between the closed roof position and the open roof position is performed by a displacing device which is not illustrated but is known per se. In the open roof position, the rear roof part 5′ and the central roof part 4′ come to lie one above the other, with the rear roof part 5′ being arranged below the central roof part 4′ in the present case.
The rear window 6 is mounted in an articulated manner in relation to the C-pillars, such that it is pivoted in relation to the C-pillars 7 during movement of the roof parts 3, 4 and 5 and, as indicated by the position of the rear window 6′, comes to lie with its curvature in the same direction as the central roof part 4′. As a result, only the C-pillars 7′ of the rear roof part 5′ are located in a lower position. However, due to the position of the C-pillars 7′ on the two sides of the trunk 9, only a very small amount of space is taken up within the trunk 9.
In order to be able to load as much luggage as possible into the trunk 9, in the embodiment according to
The embodiment of the hardtop 2 according to
The displacing apparatus can have a plurality of rotary drives which are arranged in each case on the articulated connections between the roof parts 3, 4 and 5. This assists the exact stowing of the front roof part 3 into the intermediate space between the backrest 10 and the motor vehicle tank 12 in the case of
As an alternative, the displacing apparatus can have a driving device, such as, for example, an electric motor or a plurality of hydraulic cylinders, with the roof parts 3, 4 and 5 connected to one another via respective lever arrangements (not illustrated).
The two embodiments according to
The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
