Opening/closing mechanism

OPENING/CLOSING MECHANISM

The electric motor controls the movement of the flexible rack (4) which, through the end pad (21), moves the rear inner runner (19) along the fixed guide (8).

The inner rear guide is coupled to the front inner guide (18). The rocker (22) following the profile (20) controls sliding between the two inner runners. The front pin (17) of the upper bracket (23) to which the sunroof (1) is fastened, is hinged to the fulcrum (2).

In the first part of the opening movement (up to the compass position) the rear inner runner (19) pulls the outer runner (12) by pin (10). In this phase the two pins (15), coupled with the profiles machined in the fixed cam (16), allow the raising of the pantograph (13) opening the sunroof to the "compass" position.

In the following sliding opening movement the rear inner runner (19) pulls the front inner runner (18) therefore the upper sunroof connection bracket (23), in which the pad (14) of the pantograph slides, while the pantograph stays still.

To limit the play between the mobile runners and the fixed guide (8), the runner pads (9) have been fitted with preloaded springs (11).

To limit the travel of the runners, two rubber buffers (5) have been fitted on the fixed guide (8) which act as a mechanical stopper.

The bracket (6), fitted with rubber pad (7), limits the raising of the front deflector, when the roof is open.

Pad (3), integral with the upper sunroof connection bracket (23), causes the lowering of the deflector when the sunroof is closed or open in the "compass" position.
