Opening/closing mechanism

The runner (16) slides along the guide rail (4) and is moved by the flexible rack (1).

The pantograph device (12) is hinged to the runner and the coupling with the pins and relative cams ensures the sliding of the bracket (7) when opening or closing and the raising of the rear part to open it to the quarterlight position. The raising to the quarterlight position is caused by the pin (5), fixed to the guide, engaging in the cam groove (14) while the groove (11) makes it possible to lower the inner part of the frame when the horizontal opening movement begins.

The hook (13) is hinged to the bracket which moves the channel (15) so that it always shadows the movements of the glass panel.

The rail (6) guides the horizontal movements of the roof and, when it touches the opposite surface of the guide acts as a fulcrum to open to the quarterlight position.

The pin (8) engaging the slot (3) in the guide makes it possible to slightly back-off the roof during the opening to the quarterlight position so that it does not get in the way of the front edge of the sunroof housing frame.

The external finishing trim (9) is loosely fixed to the bracket (7) so that it remains in contact with the roof.
