Abstract:
A power actuator for use in combination with a door latch and lock mechanism of a vehicle having a central locking system, said actuator comprising:(a) an actuator element (12) operatively drivingly connected with the lock mechanism in use;(b) a main drive for selective powered movement of said actuator element between locked and unlocked positions;(c) a manual locking element (14) for operative connection to a manual drive;(d) linkage serving to interconnect said manual locking element to the actuator element for manual locking and unlocking independently of said main drive, said linkage comprising a transmission connector (16) guided for reciprocating movement along a longitudinal axis of the transmission connector between locking and unlocking conditions, the transmission connector including first and second drive formations (32, not shown) coacting respectively with the actuator element and the manual locking element; and(e) a superlocking drive (20-26) acting on said linkage for selectively disconnecting the manual locking element from driving engagement with the actuator element, wherein the transmission connector is also guided for angular movement about said longitudinal axis between engaged and disengaged positions, said drive formations drivingly linking the actuator and manual locking elements in the engaged position to transmit movement therebetween by longitudinal reciprocation of the connector, and said superlocking drive having connection to the transmission connector to selectively effect said angular movement of the connector, said angular movement about the longitudinal axis of the transmission connector causing at least one said drive formations to be carried out of coacting relationship with the respective said element whereby the drive connection between the actuator and manual locking elements is disabled.
