Definitions

  • the invention relates to a locking device for a hood of a motor vehicle according to the preamble of the main claim.
  • EP 2481645 A1 and KR 20100006257 A reveal bonnet locks with pedestrian impact protection.
  • a locking device according to the main claim is used to achieve the object.
  • Advantageous embodiments result from the subclaims.
  • the aforementioned features known from the prior art can be combined individually or in any combination with one of the objects according to the invention described below.
  • a locking device for a bonnet of a motor vehicle comprising a locking mechanism with a rotary latch and a pawl for locking the rotary latch in a main latching position, the locking device furthermore having a catch hook which opens an opening movement of a lock holder after the lock has been opened Locked on one Can limit the security position between an intended closed position and an intended open position.
  • the catch hook has a load-dependent barrier and the locking device is designed such that a movement of the lock holder in the direction of the barrier at the intended closed position is limited by the barrier depending on the load, so that the lock holder only dives beyond the intended closed position in the event of an overload.
  • the rotary latch In the main latching position of the rotary latch, the rotary latch is locked by the pawl, so that rotation of the rotary latch to release the lock holder received can in principle be prevented.
  • the intended open position generally allows the motor to be viewed and / or made accessible.
  • the bonnet is raised in the intended open position at a distance from the vehicle body that allows a person to view and / or access the engine.
  • the intended closed position is used to operate the vehicle.
  • the bonnet is aligned with the visible outside in the intended closed position with the adjacent vehicle body.
  • the bonnet in the intended closed position on the inside is at a fixed distance from the adjacent vehicle body, so that the bonnet could move beyond the intended closed position in the direction of the vehicle body without the closing device and possibly hit the vehicle body.
  • the securing position is generally at a distance from the intended closed position in the direction of the intended open position, that is to say in the direction of an opening movement, such that a hand can only be inserted flat from the outside between the bonnet and the vehicle body. Only flat means that the palm is oriented parallel to the bonnet and / or a hand held transversely to it cannot be inserted between the bonnet and the vehicle body.
  • the lock holder performs a closing movement when the bonnet is closed, i.e. a movement in the direction of the barrier, starting from the intended open position in the direction of the intended closed position.
  • the closing movement or movement in the direction of the barrier basically runs along a defined and / or guided path of movement, the generally as such a guide e.g. the pivot bearing serves in particular the bonnet.
  • a pedestrian accident in which the pedestrian hits the bonnet, also results in a force on the lock holder to execute the movement in the direction of the barrier or closing movement along the movement path.
  • An opening movement and a closing movement or movement in the direction of the barrier are opposite movements, that is to say movements in the opposite direction, along the same movement path.
  • the Opening movement and closing movement or movement in the direction of the barrier are basically both a relative movement between the lock holder and the closing device. This is because the lock holder can be attached both to the bonnet and to the vehicle body adjacent in a closed position, or vice versa. Accordingly, the locking device can be attached to both the vehicle body or the bonnet.
  • the bonnet with its own weight and / or a small additional force is dropped from the raised open position and / or accelerated in the closing movement direction or in the direction of the barrier.
  • the lock holder In the normal closing process, the lock holder is limited by the barrier during its movement in the direction of the barrier or closing movement at the intended closed position, in that the lock holder preferably hits the barrier.
  • Limiting at one position means that if the lock holder reaches the position while executing a movement in one direction of movement, the movement of the lock holder in this direction of movement is stopped, that is to say limited.
  • a movement is typically limited by a stop. This applies in particular to the opening movement and movement in the direction of the barrier or closing movement as well as their limitation at an intended open position, securing position and / or closed position.
  • the excessive load can also be generated, for example, by misuse, in which a user slams the bonnet shut with particularly great force, that is to say moves it at a high speed in the direction of the barrier or closing movement direction.
  • Load means a force that the lock holder exerts on the load-dependent barrier when it moves in the direction of the barrier or when it closes.
  • Excessive load means a force above a threshold load, i.e. a threshold value for a force. Due to the known correlation of mass, acceleration and force, the threshold load can also describe a threshold acceleration if the mass of the hood is known and no additional weight, e.g. a pedestrian on it in the event of a pedestrian crash connected to the bonnet.
  • Diving beyond the intended closed position means that the movement of the lock holder in the direction of the barrier, ie the closing movement of the lock holder, continues beyond the intended closed position.
  • Diving means a closing movement in the closing movement direction or a movement of the lock holder in the direction of the barrier starting at the intended closed position.
  • the lock holder impacts or presses on the barrier with a force above the threshold load so that the threshold load is exceeded.
  • the movement of the lock holder in the direction of the barrier is then continued in particular uniformly along the movement path.
  • a locking device comprising a catch hook with a load-dependent barrier, which allows a closing movement of the lock holder or a movement of the lock holder in the direction of the barrier at the intended closed position to be limited by the barrier so that the lock holder is only overloaded in the event of an overload if the intended closed position dips down, particularly effective pedestrian protection is made possible.
  • This causes the bonnet to give way, which can reduce injuries to a pedestrian when it hits the bonnet.
  • a locking device with pedestrian protection can be provided with particularly low manufacturing costs and without or at least a particularly small number of additional parts.
  • a particularly inexpensive and compact locking device with the additional function of pedestrian protection can thus be obtained.

  • the pawl 2 is biased clockwise in particular by a pawl spring, not shown.
  • the catch hook 3 is rotatably mounted about the catch hook axis 17.
  • the catch hook 3 is biased counterclockwise in particular by a catch spring not shown.
  • the catch hook 3 has a hook shape, preferably with the shape of a "1".
  • the upper slope serves for pivoting as a result of a lock holder hitting and sliding along it during a closing movement.
  • the V-shaped recess serves as a safety stop for the lock holder after leaving the locking mechanism.
  • the hook shape represents one of two legs connected in a U-shape, the guide groove 7 running between the two legs.
  • the valley of the guide groove 7, that is to say in the region of the base of the legs connected in a U-shape, preferably forms an immersion stop for limiting the movement of the lock holder in the direction of the barrier or the closing movement of the lock holder in the event of an overload.
  • the barrier 6 and the catch hook 3 are made in one piece and / or the barrier 6 is integrally and / or non-movably connected to a base body of the catch hook 3.
  • One-piece means made from a piece of material, e.g. stamped together from a single sheet as a coherent component.
  • a cohesively connected barrier can be welded on, soldered on or glued on.
  • a barrier connected to a base body with no movement has no degree of freedom of movement relative to the base body.
  • a movement-proof connection can be established by a positive and / or non-positive connection, such as a clip connection.
  • the barrier 6 is designed such that the barrier 6 plastically deforms when overloaded, in particular in the region of an articulation axis.
  • the barrier 6 is designed such that the barrier 6 breaks at a predetermined breaking point in the event of an overload or is deformed for kinking.
  • a predetermined breaking point is usually an area with a tapered cross-section, at which the highest material stresses occur when the lock holder is loaded, so that the barrier 6 fails first at this point, i.e. at the predetermined breaking point. deforms or breaks plastically.
  • the location of the kinking and / or breaking can thus be determined particularly precisely.
  • the locking device is designed such that, in the event of an overload, the barrier 6 is bent over by the lock holder 4, preferably by the articulation axis, in particular by at least 85 ° or 90 °, preferably in the closing movement direction, so that the lock holder 4 can submerge beyond the intended closed position.

  • the articulation axis is preferably designed as a predetermined breaking point.
  • the catch arm 3, the barrier 6 and / or a material for the integral connection are made of metal or, although rare, are quite possible made of plastic.

  • the threshold load thus correlates with the yield strength of the material in the area of the articulation axis, the material thickness in this area and the lever arm.
  • the locking device is designed such that the movement of the lock holder 4 in the direction of the barrier in the event of overload at a diving position is limited by a diving stop 10 of the catch hook 3.

  • the entrance of the guide groove 7 is on the opposite side of the immersion stop 10 and / or the catch hook rotation axis 17. Because this allows the lock holder to move into the guide groove 7 by pivoting the catch hook 3 when moving in the direction of the barrier, which will be described in more detail later becomes.
  • the guide groove can ensure that the lock holder hits the barrier 6 and does not move past the barrier 6 when it is closed, for example by an unscheduled pivoting of the catch hook 3.
