OPERATION

This paragraph describes the movements of the sunroof command mechanism in detail for opening/closing to both the hidden and quarterlight positions.

The flexible racks, moved by the electric motor, command the sliding of the runners S one on each side along the longitudinal rails G.

The pantograph element E is hinged to each runner and by the pin connected to the cam grooves, determines the movements of the bracket M to which the sunroof if fixed.

The front of the bracket is fitted with a runner P which runs in a groove.

Opening the roof

If, when the sunroof is closed, and side A of the control switch is pressed, the roof will begin to open.

From the closed position (position a) the runner S is pushed backwards by the flexible rack. The pin (2) of the pantograph E is moved from the "X" position to the "Y" position along the groove in the bracket M thus causing the rear part of the panel to be lowered so that it can slide into the compartment between the inner and outer roof panels.

At the same time pin (4) enters space (5) of guide G and is engaged under the groove (3).

After the glass panel has begun to back off the runner P follows the curve (1) of the guiding groove and cause the front part of the panel to be lowered (position b).

The opening action is continued in this configuration until the runner S reaches the stop limit (6) in the guide G and the motor is deactivated (position c).
