Definitions

  • the present invention relates to a lock unit comprising at least one rotary latch, a first pawl with a pawl rotation axis and a blocking lever, wherein the rotary latch in a locked state of the lock unit initiates a pivoting moment on the first pawl and the first pawl is fixed by means of the blocking lever.
  • Such lock units are used in motor vehicles in particular for locking doors, flaps or the like.
  • the relative position between the rotary latch and pawl is not regularly formed so that the force exerted by the catch force passes through the pawl rotation axis and thus an independent fixation of the catch is made possible by means of the pawl.
  • the pawl is formed or arranged so that the force exerted by the catch force itself causes a torque on the pawl, which favors the release of the catch. In that regard, causes (only) the catch an opening moment with respect to the first pawl, so that it can be easily moved to the open position due to the spring bias of the catch and / or acting on the catch (indirectly) door sealing force.
  • a blocking lever which fixes the first pawl in the locking position (closed position), so that in particular positional shifts with respect to the locking mechanism (eg by compressing the door seals), the driving operation and the like, no (unintentional) opening of the lock unit or cause no release of the contact of pawl and rotary latch. This blocks the "self-opening mechanism" of the locking mechanism.
  • Such a lock unit is for example from the WO 2008/061491 A1 out.
  • a lock unit which also has a second pawl, which is mounted on the pawl rotational axis of the first pawl and engageable with the blocking lever and the catch.
  • a second pawl which is mounted on the pawl rotational axis of the first pawl and engageable with the blocking lever and the catch.
  • the lock unit comprises at least one rotary latch, a first pawl with a pawl rotation axis and a blocking lever, wherein in a locked state of the lock unit, the rotary latch initiates a pivoting moment in the first pawl and the first pawl is fixed by means of the blocking lever.
  • a second pawl is also provided, which is mounted on the pawl pivot axis and engageable with the blocking lever and the catch. Further, the first pawl has a curved first locking surface for a main catch of the rotary latch.
  • the lock unit is in particular a lock for a motor vehicle door, wherein the lock unit can in principle also be provided on other doors, flaps, etc.
  • the function of the so-called locking mechanism of rotary latch and pawl in motor vehicle locks is basically known, so that it should only be mentioned that by means of the (spring-loaded) catch a lock holder (also called locking pin) added and locked in a locked state (or closed position) becomes.
  • a lock holder also called locking pin
  • To lock the rotary motion of the rotary latch it has on its outer periphery a so-called main catch into which the first pawl engages.
  • the first pawl performs a rotational movement and finally forms with the catch a contact area, in the catch and pawl abut each other.
  • the first pawl and the second pawl are arranged pivotably on a common pawl rotation axis. Since these pawls regularly cooperate at different times with the catch, a relative movement of the two pawls is mutually possible. For these pivoting movements of the pawls come next to so-called release levers and spring elements, dampers, Baudenmann, electric motor drives and the like into consideration.
  • the pivoting movement of the pawls is regularly by end stops (in particular, for example, on a pawl and / or the blocking lever) and / or other components of the lock unit limited, wherein advantageously the pivoting range is kept small.
  • the first pawl has a curved first locking surface for a main catch of the rotary latch.
  • the first locking surface has such a curved contour that the rotary latch, which regularly has a substantially flat locking surface, an approximately band-shaped or even linear contact with the first locking surface of the first pawl forms.
  • the first blocking surface may be formed in particular convex.
  • the blocking lever may have at least one first actuating limb for the first locking pawl, a second actuating limb for the second locking pawl and one articulation arm for at least one restoring element.
  • the multi-pawl locking mechanism now interacts in particular in the respective latching positions of the rotary latch and / or in subsequent movement sequences with the blocking lever.
  • This is also embodied here as a complex component which has spatially separated actuating arms for interaction with the pawls arranged one above the other, wherein these are formed, in particular, by spatially spaced-apart contact areas towards the first pawl and second pawl.
  • these contact areas are also arranged in different planes perpendicular to the pawl rotation axis.
  • actuating legs for the first pawl and the second pawl allows the stop surfaces the pawls can be arranged further apart.
  • small pivot angle of the pawls and / or the blocking lever and low actuation forces can be realized.
  • the pawls themselves can be made relatively small, so that here, if necessary, very slim components can be used.
  • the restoring element regularly exerts a pivoting moment and / or a force on the articulation arm, so that a secure abutment of the blocking lever on the first pawl, the second pawl and / or another lock component is realized.
  • this externally acting restoring element serves to maintain a stable position even during the fast-running sequence of movements within the lock unit during the opening operation and / or during the closing operation, in particular impact noises due to vibrations etc. are avoided.
  • the provision of the separate Anlenkarms supports the space-saving arrangement of the return element and optionally a simple installation of the return element in the event of wear.
  • the restoring element can be made smaller due to the large distance to the block lever pivot axis, whereby also space can be saved or spatially removed.
  • the blocking lever has a blocking lever pivot axis and the articulation arm is arranged in this respect opposite to the first actuating leg and the second actuating arm.
  • the two actuating limbs are arranged on one side of the blocking lever pivot axis and the pivot arm is arranged on the other side of the blocking lever pivot axis.
  • the first actuating limb for the first pawl and the articulation arm are arranged such that an imaginary connecting line runs approximately through the blocking lever pivot axis.
  • the second actuating leg is in this Case z. B. in the manner of a lateral, emanating from the first actuating leg offshoot.
  • This also has the particular advantage that, for the closed position of the lock unit, in which the first actuating limb is in contact with the first pawl, the contact force of the first pawl in the direction of Blockadehebelwindrehachse and due to the large distance towards the contact area with the second Actuating leg towards the second pawl low release forces for the relative movement of the first actuating arm of the blocking lever and the first pawl are introduced.
  • the operating comfort and the noise can be significantly improved.
  • the blocking lever only temporarily contacts the restoring element with the articulation arm.
  • the restoring element is stationarily positioned in the pivoting region of the blocking lever or its actuating limb and / or its articulation arm.
  • the return element interacts with the blocking lever, for example, only in specific positions, such as the closed position of the lock unit and / or the pre-locking position and / or the open position.
  • spring elements, damping elements, etc. come into consideration.
  • the blocking lever contacted with several reset elements during its entire pivoting range (one after the other), whereby also a reset element can act permanently and another only temporarily.
  • the restoring elements may also be of different nature (springy, dampening).
  • the embodiment described here of the blocking lever is optionally also independent of the aspect the curved locking surface in lock units with multiple pawls and a self-opening mechanism advantageous. These could therefore be realized and used independently.
  • the first pawl has a first locking surface for a main catch of the rotary latch and a stop surface for the blocking lever, wherein the first locking surface and the stop surface are arranged differently far away from the pawl rotation axis.
  • the invention solves in particular the widespread view that the blockage is realized opposite to the main branch. Rather, it is proposed here that the contact region of the main catch and the first blocking surface is arranged closer to the pawl rotational axis than the contact region of the stop surface and the blocking lever. It is particularly preferred that the contact region between stop surface and blocking lever, starting from the pawl rotation axis, at least 10 mm, possibly even at least 25 mm, is arranged further radially outward.
  • the first pawl adjacent to a stop surface for the blocking lever forms a recess for the first actuating leg.
  • the recess may in particular also be formed as an undercut, into which the actuating limb, for example with the aid of the return element, dips.
  • the system can be guided on the first pawl. This also prevents the blocking lever from striking the environment during operation of the lock unit and / or in the locked position during operation of the motor vehicle and thus producing noise.
  • the invention finds particular application in a motor vehicle which has at least one lock unit designed according to the invention.
  • the Fig. 1 shows a schematic and perspective view of a multi-part locking a lock unit 1.
  • a central component of the lock unit 1 is the rotary latch 2, which is rotatably mounted about the rotary shaft rotation axis 18 (spring-biased).

This is also done with respect to the first pawl 3, wherein this (also biased counterclockwise) in front of the main catch 13 is incident, in particular until the rotational angle stop 30 of the first pawl 3 rests against the rotary latch 2.
  • the blocking lever 5 is thereby equally pivoted on the return element 10 and positioned with its first actuating leg 7 in front of the stop surface 15 of the first pawl 3. In this position, the articulation arm 9 also comes to rest on the damper 20, so that in the closed position the second Pawl 6 and the blocking lever 5 in contact with the damper 20 are.
  • FIG. 4 presses in the event that the first actuating leg 7 is removed from the stop surface 15 of the first pawl 3, the rotary latch 2 with its main catch on the curved first locking surface 12, so that the first pawl 3 is pushed away.
