The present research works with specific linkages applied to displace the roof top of convertible vehicles, consisting either in a simple linked quad-bar mechanism or a complex multi-contour z-bar structure. The roof top which can be on or off is made either of two or three hard roof top components or a flexible fabric. For the flexible roof, the reserved space in the trunk is a significantly smaller, occupying just a fraction of the volume intended otherwise for luggage. The retractable linkage of the roof top is a planar kinematic spatial structure with connected bars which allows the moving top parts to be piled up inside the reserved trunk section. It is important to take note that the first roof top element of the kinematic structural chain is the car trunk hood at the rear side of the vehicle. The screen is second moving part and the third is in this case the retractable flexible top. Folding the car roof top and the rear window in the trunk is based on the fact that its door is previously actuated through a single hinge pair or a quad-bar mechanism. For some specific passenger cars, the roof top is made out from multiple elements and in a strong connection with the rear window of the car creates the open kinematic spatial structure that may be folded up through structural kinematics.
