Definitions

  • the invention relates to a method for actuating a pawl in a lock with a rotary latch for a motor vehicle.
  • Methods for actuating pawls in motor vehicle locks are known.
  • DE 197 06 657 AI describes a lock for a movable arrangement such as a door, tailgate or the like of a vehicle with an actuator for driving a pawl, in which a further actuator is provided for the direct or indirect drive of the pawl.
  • the pawl is actuated, it is provided that the pawl is returned to the starting position by spring loading or by reversing the direction of rotation of the actuator. In an emergency, however, this can be disadvantageous.
  • the invention is therefore based on the object to provide a method for actuating a pawl in a lock with a rotary latch for a motor vehicle, in which the actuators used are supplied with current both in the normal case and in an emergency in such a way that under
  • the object on which the invention is based is achieved by a method for actuating a pawl in a lock with a rotary latch for a motor vehicle, in which the pawl, which is in the closed position and is rotatably mounted about a pivot point, normally has a first actuator which is operated by a Main power supply is controlled, and via a gear segment, which is also rotatable about the pivot point and has a freewheel opposite the pawl, is rotated until the open position is reached or, in an emergency, via a second self-locking actuator, which is controlled by an emergency power supply, via another, rotatably mounted gear segment that carries a gear with a smaller diameter that engages in the gear segment, is rotated until the open one Position is reached and then the emergency power supply is interrupted and the pawl remains in the open position.
  • Electric motors can be used as the first actuator and as the second self-locking actuator. It is also possible that a self-locking actuator is also used as the first actuator. If the pawl is in the closed position, it engages directly in the rotary latch, whereby the lock remains locked. After the emergency power supply is interrupted, the pawl remains in the open position. This is due to the self-locking effect of the second self-locking actuator. It has surprisingly been found that particularly high safety precautions in an emergency can be set in a relatively simple manner by the fact that the pawl remains in the open position. This applies to the entire time in which only the emergency power supply for the lock with rotary latch is available for a motor vehicle. A disadvantage
  • a preferred embodiment of the invention is that in a subsequent step, the second self-locking actuator is controlled by the main power supply until the self-locking effect is canceled and the pawl by the spring force of one
  • Pawl spring reaches the closed position. This step is carried out when the main power supply for the lock with rotary latch is again available for a motor vehicle. This eliminates the need to hold the pawl in the open position.
  • the second self-locking actuator is then controlled directly by the power supply and thus loses its self-locking effect, which previously could keep the pawl in the open position to improve the safety precautions. It is advantageous that the position of the rotary latch can be adapted to the emergency situation that has weakened at this point in time. It is then again possible to lock the lock with the rotary latch for a motor vehicle by inserting the locking bolt into the rotary latch, which is quite desirable at this point in time.
  • the emergency power supply is provided by a capacitor.
  • a gold cap such as that sold for example by Panasonic, can be used particularly advantageously as a capacitor. Because of its high capacitance, such a capacitor is particularly advantageously suitable as a bridging voltage supply.
  • Fig. Shows a part of the lock with a rotary latch for a motor vehicle in plan view.
  • a part of the lock with rotary latch 2 for a motor vehicle is shown in plan view.
  • the pawl 1 which is in the closed position and is rotatably mounted about a pivot point 3
  • the pawl 1 is normally actuated via a first actuator 4 which is controlled by a main power supply 11 is, and via a, also rotatably mounted about the pivot point 3 gear segment 5, which has a freewheel opposite the pawl 1, in rotation. This continues until the open position (not shown) is reached.
  • the control of the first actuator 4 takes place starting from the main power supply 11 via a line 11 ⁇ .
  • the actuator 4 is connected to the gear segment 5 via a first pinion 4.
  • the pawl 1 In the closed position of the lock shown with the rotary latch 2 for a motor vehicle, the pawl 1 is biased by a pawl spring 10 and the rotary latch 2 is biased by a rotary latch spring 12. If the main power supply fails in an emergency
  • a second self-locking actuator 6 is controlled by an emergency power supply 7.
  • the second self-locking actuator 6 is connected via a second pinion 6 ′ to a further, rotatably mounted gear segment 8, which carries a gear 9 with a smaller diameter.
  • the gear 9 engages directly in the gear segment 5.
  • the emergency power supply 7 can actuate the pawl 1 in an emergency until the open position is realized. Then the emergency power supply 7 is then interrupted and the
  • Pawl 1 held in the open position. This is done by the self-locking effect of the second self-locking actuator 6, which remains in its position after switching off the emergency power supply 7 and thereby holds the pawl 1 in the open position.
  • the second self-locking actuator 6 is actuated by the emergency power supply 7 by the other one Management. 7. If the emergency power supply 11 is available again after some time, the second self-locking actuator 6 is directly controlled by the main power supply 11 via the second line 11 V ⁇ , thereby eliminating the self-locking effect. Due to the spring force of the pawl spring 10, the pawl 1 can then advantageously move into the closed position, so that the door can be closed again by inserting the locking bolt 14 into the rotary latch 2. Electric motors are advantageously used as the first actuator 4 and as the second self-locking actuator 6. A capacitor can advantageously be used as the emergency power supply 7. The respective position of the rotary latch 2 can additionally be detected and monitored at any time with the aid of a rotary latch switch 13. With this information, the control of the main power supply 11 or emergency power supply 7 can be optimized.

Abstract

L'invention concerne un procédé selon lequel un cliquet d'arrêt (1) monté de façon à pouvoir tourner autour d'un centre de rotation (3) et se trouvant en position de fermeture est mis en rotation, dans des circonstances normales, par l'intermédiaire d'un premier mécanisme d'actionnement (4) commandé par un bloc d'alimentation principal (11), ainsi que par l'intermédiaire d'un segment de roue dentée (5) également monté de façon à pouvoir tourner autour dudit centre de rotation (3) et en roue libre par rapport audit cliquet d'arrêt (1), jusqu'à ce que ce cliquet d'arrêt soit en position d'ouverture. En cas d'urgence, le cliquet d'arrêt (1) est mis en rotation par l'intermédiaire d'un second mécanisme d'actionnement à blocage automatique (6) commandé par un bloc d'alimentation d'urgence (7), ainsi que par l'intermédiaire d'un autre segment de roue dentée (8) monté de manière rotative et supportant une roue dentée (9) qui présente un diamètre inférieur et s'engrène dans ledit segment de roue dentée (5), jusqu'à ce que le cliquet d'arrêt soit en position d'ouverture. Ensuite, le bloc d'alimentation d'urgence (7) est déconnecté et le cliquet d'arrêt (1) est maintenu en position d'ouverture.
