Section T0 - T1

During this phase the intermediate runner (B) moved by the rack fastened in (3) pulls the rear runner (C) via pins (6 and 8); the rear runner in turn pushes the front runner (A) by pin (1) of the carrier bracket (2). Pins (6 and 8) do not run along the profiles of cams (5 and 7) as the counter piece (4), inserted in the guide only allows longitudinal translation of the kynematism.

Section T1 - T2

In position T1 the reference (9) of the rear runner (C) reaches its front stroke limit stopping against the stopper (10) on the guide and the counter piece (4) is in correspondence of slott (11); this way the pantograph device is released, allowing pins (6 and 8) to run respectively along the profile of cams (5 and 7). The intermediate runner (B) moves along the guide until piece (15) sets itself on the microswitch (M), position T2, causing the motor to stop. During this section the intermediate runner (B) which pushes the front runner (A) through the combined action of the two cams (14 and 15) on pins (16 and 17). The motion of the front runner causes the movement of the connection pin (1) of the carrier bracket (2), along the profile of the front cam (12); the action of the pantograph device and the running along the front cam enable the raising of the sunroof which reaches the position flush with the body (roof closed).
