  • Patent number: 5338089
    Abstract: The application relates to a convertible automobile with a windscreen which is arranged behind a row of seats and which extends vertically upwards and beyond the top of the seats and which extends for the entire interior width of the vehicle. In order to develop a windscreen of this type in such a way that annoying draft phenomena are prevented while the typical "convertible feel" is maintained, the windscreen is formed by a stretched elastically deformable net which causes a deceleration of the air flow impinging from the rear of the vehicle towards the front.

  • Patent number: 5211718
    Abstract: A convertible motor vehicle is provided with a wind-deflecting cover which covers the space behind a front row of seats at the top. A windscreen is secured on the cover and, in the operative position, projects approximately vertically from the level of the upper edge and can be lowered into an out-of-use position. The windscreen is formed by a roller blind having a winding-up roller fixed at a forward boundary edge of the cover. An alternative arrangement for accommodating a windscreen on the cover in the out-of-use position forms a single unit with the cover which has two panels resting one upon the other and arranged to be swivelled open at a hinge. Opposite to this hinge, the windscreen is swivellably fixed at a forward boundary edge of the lower panel and can be swiveled in between these panels.
