The invention relates to a retractable roof for passenger vehicles, especially a hard top for two-seater convertibles, roadsters or similar, comprising a dimensionally stable shell consisting of a roof part and rear support pillars which are rigidly connected to the roof part at an obtuse angle, a rear window for a window opening and an accommodating area located perpendicular to the longitudinal axis of the vehicle directly behind the seats, wherein the roof part can be moved in and out with the support columns thereof by means of guiding and drive means. The roof part is kinematically and restrictively guided on a guide track with the support pillars thereof. The aim of the invention is to provide a retractable roof of the above-mentioned variety which exhibits the required structural rigidity yet which is lightweight, operates smoothly and is mechanically simply and easy to use while at the same time being compact. Said aim is achieved by making the guide tracks, which consist of rails, extend in a straight line in the direction of the boot, parallel to the longitudinal axis of the vehicle, whereupon the support pillars of the roof part are displaceable thereon by means of guide carriages fixed to the support pillars and are rotationally guided about a transversal axis which is horizontal in respect to the longitudinal axis of the vehicle, and by allocating a separate control track with endless guiding means to each guide carriage in order to produce a combined translational and/or rotational movement of the support pillars. The guiding means are coupled to each other in a positive fit by means of a common shaft, which is driven by a drive mechanism, in order to produce a synchronous movement. When a rear stop is reached, the front end of the roof part can pivot into the accommodating area in a position which is approximately perpendicular to the rear of the seat group and the support columns can be lowered inside said accommodating area.
