OPERATION

This chapter gives a detailed description of the movements of the sunroof control mechanism which cause "compass" opening and complete opening by sliding. The flexible racks, moved by the electric motor, control the movement of runners S1, one on each side, along the fixed longitudinal guides G. Runner S1 controls the movement of the front runner S2 and of the rear runner S3. The pantograph C is hinged to runner S3. Through pins which engage in special profiles on a fixed cam (E), the pantograph causes the upward movement of the sunroof connection bracket. The bracket is hinged at the front to runner S2 in point D.

"COMPASS" OPENING

Starting from the sunroof closed position and operating the control switch (press A) the sunroof opening phase begins. From the closed position (Fig. 7a) the runner S1 is pushed backwards by the flexible rack. Runner S2, therefore hinge D which restrains the sunroof at the front, remain still due to the effect of pin (5) engaged in the slot of guide G (position X). Runner S3 is pulled by the position of the rocker pin (1). As the runner S3 moves backwards, the pantograph C rises because of the trajectory imposed on the pins (2) by the profiles (3) machined in the fixed cam (E) (Fig. 7b). This way pad (4) makes the sunroof connection bracket rise, taking the sunroof with it to the "compass" position.
