<p>A latch including an actuator having a stepper motor, a displacement means having a first position, a second position, and an intermediate rest position between the first and second positions, a third position, a fourth position, and a corresponding further intermediate rest position between the third and fourth positions, the displacement means including first and second driving surfaces, the actuator including an output movable between first, second, third and fourth sequential output positions, each of which correspond to first, second, third and fourth latch statuses respectively, the output including first and second driven surfaces, in which the stepper motor is capable of being powered to move the displacement means from the intermediate rest position to one of the first or second positions and then to return the displacement means to its intermediate rest position, and in which the stepper motor is capable of being powered to move the displacement means from the further intermediate rest position to one of the third or fourth positions, and then to return the displacement means to the further intermediate rest position, the first and second driving surfaces and the first and second driven surfaces being arranged such that the output may also be moved between the first and second output position or between the third and fourth output position independently of the displacement means. <IMAGE></p> |
