Abstract

Activation and locking device for opening and closing a sun roof for a motor vehicle which includes a tow-sliding carriage (24) coupled to an entraining body (111) through grooved side levers (28) wherein fulcrum pins (26) of round sector lever (13) provided with a toothed round sector (14) engage. The lever (13) and said entraining body (111) are coupled to a shaped lever (5) for the hooking and support of the sliding glass or cove ring (1) of the sun roof. The assembly of carriage (24), entraining body (111) and shaped lever (5) slides in guides provided in guide section (20). The carriages (24) are provided with front side arms (122) having longitudinal eyelets (132) wherein engage the side sliding slides (115) of the entraining body (111), the through pins (118) provided at the front ends (117) of shaped lever (5) and pins (160) of lock-teeth (161). A locking system is provided having a pin (180) coupled to a corresponding side groove (81) provided with an opening (84) and an upper internal filleted wall (85).
