ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to a convertible vehicle with a rear window, which can be lowered below a window parapet line forming the upper boundary of the car body.
DE 43 20 603 C2 shows a convertible vehicle, for which a rear window is held in a shaft, which is fitted transversely in a vehicle car body and held separately from the roof construction and can be shifted from an inoperative open position of the rear window in this shaft upwards into a closed position for sealing the folding top at the rear. For assembling such a convertible vehicle, it is necessary to align the roof construction with respect to the car body and to adjust the shaft module, comprising the window in the inoperative position, with respect to the car body and with respect to the roof construction. This increases the adjusting work during the assembly appreciably. In addition, the module, accommodating the window, is a heavy and bulky component which, because of its extent in the installed state, shortens the trunk space.
From DE 36 07 650 A1, a convertible vehicle is known, the rear window of which can be shifted by two pairs of levers, together with its frame, from a position, closing the rear window opening, into a stowage position, which is remote from the roof. Such a lever mechanism is exceedingly expensive and requires much space in the vehicle. Moreover, in the closed position, the frame, holding the rear window, is pressed only against the outlet opening, so that sealing problems arise there.
SUMMARY OF THE INVENTION
It is an object of the invention to improve a convertible vehicle of the type named above with regard to its installation properties.
By the inventive holding of the rear window in a frame, firmly connected with the roof, an adjustment of a further component with respect to the folding top is avoided. In the normal position as well as in the lowered position, the rear window remains connected with the folding top. With that, it is aligned adequately merely by adjusting the roof and is installed in the vehicle together with the roof in the same way as a fixed rear window.
It is particularly advantageous that the window, in the lowered position, is suspended below the leading edge freely in the car body, so that further bulky and heavy components are unnecessary.
In a particularly advantageous development, the rear window can be swiveled up with respect to the frame, which is open downward. Consequently, during the opening or closing of the roof, the frame, with the rear window swiveled up, can be guided over obstacles such as any headrests or roll bars, which would collide with the rear window, if the latter were in the closed position. As a result, particularly in the case of four-seater convertibles, very advantageous, kinematic swiveling up conditions can be created for the roof, which results in more headspace for the persons seated in the back and, at the same time, advantageous optics. Moreover, if the rear window is in an approximately vertical position, the visibility towards the rear is very good.
Further advantages and distinguishing features arise out of the examples of the object of the invention shown in the accompanying drawings and the following description.
