Sunroof structure

SUNROOF STRUCTURE

All the sunroof components are housed on a frame (6) fastened to the body between the roof of the car and the roof lining.

At the front of this frame we find the electric motor (12) and the corresponding control relay (15). Microswitch (14) is fastened on the motor which through a special cam on the output spindle detects the "zero" position corresponding to the position of the runners concerning "compass" opening.

At the end of the electric motor spindle there is a toothed gear (13) which meshes with the flexible racks (16) making them slide inside special guide tubes.

The runner (9) is fastened at the end of each rack, which, with its movement along the guides (18) determines the various movements of the sunroof.

In fact, the coupling between special pins and suitable cams, the longitudinal movement of the runners determines the type of movement of the upper brackets (1 and 8), to which the glass sunroof (4) is fastened; this way the compass opening movement and the following sliding motion is determined by the position of the runners.

The metal frame of the glass sunroof is fastened to brackets (1 and 8) by six screws. The holes of these screws are slotted to allow vertical and longitudinal adjustment of the sunroof.
