<p>1. Electromechanical device for controlling the opening of a lock, especially a lock for a motor-vehicle door, comprising a locking mechanism (10, 18) intended for detaining a keeper (G) and connected to an electromechanical device (31, 72, 78) for controlling the opening of the lock by means of a sliding coupling member (7) shifted by the electromechanical device and equipped with means for driving an articulated bolt (18) of the locking mechanism, characterized in that it has a screw (72) which is driven in rotation by means of an electric motor (31) and on which is shifted in a translation movement a nut (78) which has a threaded hole (80) and a bore (82), the axes of which intersect, the diameter of the bore (82) being slightly larger than that of the screw (72), and which drives a lever (94) acting on a stud (100) of the coupling member (7) in order to shift the latter and cause the bolt of the lock to pivot in the opening direction, and means (86, 92) for causing the nut to tilt between a lock-opening position, in which the threaded hole is engaged with the screw, and a disangaged position in which the bore is coaxial relative to the screw.</p> |
