A method for opening and closing a retractable roof of a convertible vehicle, wherein the roof includes a first portion and a second portion, connected together. The method includes: moving the first portion relative to the second portion between a first position and a second position, such that, at the first position, the first portion is at least partly superposed on the second portion and, at the second position, the first portion lies in substantially the same plane as the second portion, rotating the first and second portions about an axis of rotation, and translating the superposed first and second portions between a first position and a second position, such that, at the first position, the first and second portions are inside a compartment in the vehicle and, at the second position, the first and second portions are outside the compartment.

A roof system (12) for a cabriolet vehicle (10) has a folding top (14) that is movable between a deployed position and a retracted position covered by a folding-top compartment lid (18). A side fin (16) is movable from a use position, in which the side fin (16) forms a rearward elongation of a support pillar (22), into a pivoted-away position, in which the side fin (16) is swiveled away from the folding-top compartment lid (18) about a swivel axis and into a pivoted-in position in which the side fin (16) is below the folding-top compartment lid (18). Movement of the side fin (16) away from the folding-top compartment lid (18) enables the side fin (16) to be positioned closer to or in the range of movement of the folding top (14) and the folding-top compartment lid (18) during movement between the deployed and retracted positions.

Method of functioning the retractable hard top system for convertible vehicles which implies splitting the ceiling in the middle (through the longitudinal axis of the vehicle), moving the rear window with the frame-like area around it on top of the trunk lid, opening the upper areas of the rear wings and folding compactly the remaining components of the roof inside the lateral areas of the trunk. This method significantly increases the usable volume of the luggage compartment and offers an easier access to the items carried in the trunk. Also, this method requires a less complex operation system which leads to less expensive manufacturing and maintenance costs.
