ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to a convertible vehicle with a foldable roof which is provided with a rear window.
Such a convertible vehicle, on the one hand, can be used with a completely open roof and, on the other, when the roof is closed, offers the possibility of opening the rear windows separately. For this purpose, a modular shaft can be provided, which has an opening gap, intended for the rear window and sealed at the top. In this connection, it must be ensured that the rear window can be transferred from a roof frame part, without being tilted, into a car body frame part of the module and vice versa. In addition, for opening the roof while the rear window is in the closed position, it must be possible to tilt the rear window without having it collide with the module in the car body, accommodating it and sealed towards the top.
SUMMARY OF THE INVENTION
It is an object of the invention to provide advantageous relationships in this regard.
Pursuant to the invention, this object is accomplished in a convertible vehicle including a car body comprising a roof movable between a closed position and an open position and including a rear window movable when the roof is in the closed position between a first position in which the rear window is situated m connection with the roof and a second position in which the rear window is situated in the car body. The roof also includes a roof frame part for retaining the rear window when the rear window is in the first position. Two lateral clamping collars each support a respective lateral side of the roof on the car body and a transverse connecting part connects the clamping collars. The clamping collars preferably have a substantially triangular shape. A car body frame part is arranged in the car body for retaining the rear window when the rear window is in the second position so that a guideway is defined by the roof frame part and the car body frame part in which the rear window moves. The roof frame part is separated from the car body frame part by a space whereby the transverse connecting part passes through the space between the roof frame part and the car body frame part during the movement of the roof between the closed and open positions.
By the cross-connection of the triangular clamping collar, a high torsional rigidity is achieved and the possibility that the lateral parts of the roof can tilt towards one another is avoided. The precision of the folding and unfolding of the roof is improved by these means. Accordingly, a very accurate course of movement can be maintained, which also makes possible small tolerances and distances of the components from one another.
By means of the inventive interruption of the guideway (i.e., in view of the spacing between the car body frame part and the roof frame part), it is ensured that the cross-connection part can be pushed over the upper edge of the module on the car-body side when the roof is unfolded, without causing a collision.
If two lateral intermediate guiding parts are disposed in the interruption (i.e., in the space between the car body frame part and the roof frame part, the rear window can be moved with little clearance in the guideway. The guidance of the window is improved by these means, especially when the window is raised from the lowered position.
The cross-connecting part may be constructed, for example, as a pipe, so that the costs of preparing such a component are slight.
An optically particularly unobtrusive arrangement of the cross-connecting part can be achieved when this part is disposed below the plane of a rear part of the cover, covering this transverse connecting part in the opened state of the roof. To avoid a collision while opening the roof, the cross-connecting part, together with the intermediate guiding parts firmly connected to it, can be moved in a guideway extending upward and rearward. Such arrangements are advantageous particularly in a convertible, in which the rear window stands essentially vertically even in the closed position.
Further advantages and details arise out of the example of the object of the invention, shown in the accompanying drawings and as described hereinafter.
