Abstract: A lock assembly (10) includes a non-manual actuator (12) coupled to a drive member (37), and a clutch member (38) formed with a groove (39) in which an engagement element (62) is disposed. The engagement element (62) is movable towards and away from a cam surface (46) which is arranged to move a lock element (56). The lock element (56) is also connected to a manual actuator (60). In a first orientation, the engagement element (62) does not protrude out of the groove (39) and does not abut against the cam surface (46), so that the non-manual actuator (12) is disengaged from the lock element (56). In a second orientation, the drive member (37) is movable by the non-manual actuator (12) so that the drive member (37) causes the engagement element (62) to protrude out of the groove (39) and abut against the cam surface (46), so that the non-manual actuator (12) is engaged with the lock element (56).
