Roof Assembly

Roof Assembly

The completely ready-made roof assembly is fitted and bolted to the roof opening from below. A sealing strap that runs all the way around seals the joint between the roof assembly and body.







The roof assembly comprises the following main components:










The roof line and the division of glass areas is designed to achieve as flat a look as possible when the glass sliding roof is moved back under the rear window. A compact guide mechanism in the sliding sunroof ensures comfortable interior dimensions without forfeiting the roof line that is typical of the 911.

The maximum transport volume in the interior with the rear seat backrests folded down is -> volume: 230 liters thanks to the modified roof line guide and the further recessed trim panel on the rear cross member, thus offering -> volume: 25 liters more space than in the Coupe.







The backbone of the glass roof assembly is an integral steel-plate assembly frame, which accommodates the glass sliding roof with drive mechanism, air deflector, roller blind and hinged rear window as well as the closing aid.

The design and mechanics of the roof assembly are essentially the same as on the previous model (996).

The assembly frame has an integrated water management system, which clears away any water that drops down when the sliding sunroof or rear window is open. A bar between the glass sliding roof and rear window is used for fitting centre-joint and rear lid seals and for affixing the sliding roof seal.

The complete roof assembly is secured to the roof pillars, the windscreen frame and the rear cross members from below. Black-tinted Plexiglas covers, with their thinly protruding rubber lips overlapping the glass elements, form a flush transition to the body. They not only minimise wind noise, but their black, high-gloss surface also adds to the glass look.

The lift mechanism joins the glass sliding roof to the assembly frame and its guides. On the new 911 Targa 4/4S models, this lift mechanism has an optimised spring mechanism with three cup springs, which absorbs transverse acceleration caused by vehicle movements and prevents noises, particularly on bad road surfaces. When lowering the roof, the lift mechanism is guided in a two-section plastic gate link, which is riveted to the sides of the assembly frame.

Guide rails are riveted to the retaining frame of the roof assembly at the left and right to facilitate longitudinal movement of the glass sliding roof. Two sliding blocks, which carry the sliding roof, run to the left and right in each of these aluminium extruding-press-section rails. Damping with respect to the vertical axis has been improved by using a new limit stop in the guide rail.
