The latch comprises a case fixed to the door, in which is provided a cavity for a keeper (3) integral with the body of the vehicle, this case containing a bolt (4) having a notch (7) for receiving the keeper (3) and a cam (22) cooperative with the keeper (3), a disc (5) rotatively mounted on a transverse pin (6) and on which the bolt (4) is also rotatively mounted, an opening (20) being provided in the disc (5) to permit the passage of the keeper (3); the latch comprises a pawl (11) pivotally mounted on the disc (5), provided with a head portion (13) which is capable of engaging into a recess (15, 16) of the bolt (4), and a safety disc which may be manually actuated for opening or closing the latch in the event of a breakdown of the electric system (9, 42, 41, 8, 44, 46, 48, A,B) controlling the rotation of the bolt (4) and the disc (5).

A latch which is electrically opened and closed, in particular for a door of an automobile vehicle having a body, the latch comprising a case for fixing to the door, in which case is provided a cavity, a keeper for mounting on said vehicle body, a bolt mounted in the case and capable of being driven by the keeper so as to close the latch, the latch further comprising in combination: (a) a pin fixed to the case, a first disc and the bolt being rotatably mounted on the pin, the disc defining an opening for allowing the keeper to engage therein, and a notch in the bolt for receiving the keeper at the beginning of a closing cycle; (b) means for driving the bolt in rotation in either direction during latch closing and opening cycles, said means comprising a toothed sector integral with the disc, an electric motor having an electric supply circuit, and a kinetic chain drivingly connecting the motor to the sector; (c) two spaced-apart recesses in the bolt, a pawl pivotally mounted on the disc and having a projecting head portion, an elastically yieldable means combined with the pawl to bias the head portion of the pawl to enter one of the two recesses in the bolt when said one recess is positioned in facing relation to the head portion so as to establish a connection for driving the bolt in rotation by means of the disc; (d) a control device for controlling the motor and cooperative with the pawl for actuation by the pawl at the beginning of a latch closing cycle so that the insertion of the head portion of the pawl in one of said recesses of the bolt actuates said device which then causes rotation of the motor in a first direction and consequently rotation of the disc and the bolt until complete closure of the latch with a disengagement of the pawl relative to the control device, and means further cooperative with the pawl for automatically causing stoppage of the motor at the end of a latch opening cycle; (e) a safety disc rotatably mounted on said pin, means for normally locking the safety disc against rotation relative to the case, means for manually unlocking the safety disc relative to the case in the event of breakdown of the electric supply circuit of the motor and driving the safety disc in rotation, fixed ramps carried by the safety disc and so adapted and arranged as to be capable, from any position of the bolt, the first disc and the pawl, for example from a latch closing position, of pivoting the pawl and causing the head portion of the pawl from withdrawing from said one of said recesses of the bolt so as to release the bolt from the pawl, then driving the bolt so as to release the bolt from the pawl, then driving the bolt in rotation in a latch opening direction to an automatically opening angular position in which the keeper assumes a driving function and drives the bolt to a complete opening of the door, the disc and the ramps also permitting the closure of the latch from the latch opening position or from an intermediate position.
