Abstract
The design of rear side windows of convertibles (cabriolets) and their
motion while being retracted contains interesting geometric and kinematic issues.
On the one hand, the space between the door and the rear wheel arch is limited.
On the other hand, the window pane has to move through the sealing slit with
as little friction as possible. These turn out to be two severe constraints for the
window surface and its motion.
In order to allow for the crammed conditions we rst compute a spatial motion
that assumes prescribed positions and obeys certain side conditions. Having obtained this spatial motion we can replace the given window surface by a kinematic surface which perfectly moves through the sealing slit. Eventually, we construct a set of possible window surfaces. This way the engineer gets a variety of options to choose from.
