摘要

The front (13) or rear rod of the upper or lower four-point joint is connected directly to front or upper rod in the bottom joint (2) or linked via a hinge arm to this joint (2). The control lever (20) pivots round a vehicle cross-axis on rod (7). The control lever (20) is connected at one end via two-arm joint to front or rear (7) rod of the top (2) or bottom (3) four-point joint. A third roof part between leading (1) and trailing (19) parts pivots round an axis halfway along the roof part (19) and joined to this part (19) so the third roof part stands between the opposing roof parts (19) stays. The third midway roof part is controlled by an arm pivoted round a vehicle cross axis and thus linked to the coupling element (12). Four-point joints (2,3) should be sited both sides of the vehicle.
