Definitions

  • the present invention relates to a lock unit for a motor vehicle comprising at least one rotary latch with a pre-latching and a main latch and two pawls which block the rotary latch in certain positions.
  • a blocking lever is additionally provided which fixes the first pawl.
  • Such lock units with multi-part pawls are known for example from WO 2008/061491 Al.
  • lock units with multi-part pawl has already proven itself outstanding and is characterized in particular by the high operating comfort and low noise during operation of the lock unit.
  • Such lock units are used in particular in doors and / or flaps of motor vehicles.
  • a lock unit should be specified, which is designed to save space and can be operated quickly and quietly.
  • the lock unit according to the invention for a motor vehicle has at least the following components: a catch with a pre-catch and a main catch, a first pawl with a first pawl axis, with the
  • Main latch is engageable, a second pawl which is mounted on the first pawl axis and which is engageable with the pre-latch, a blocking lever with a blocking lever axis which fixes the first pawl when it is engaged with the rotary latch, and a release lever for pivoting at least the blocking lever, wherein the release lever so cooperates in the ⁇ ffhungsvorgang with the blocking lever, that the first pawl and the blocking lever are pivoted in the same direction of rotation.
  • the lock unit is used in particular for locking doors in a motor vehicle.
  • the lock unit in addition to the above-mentioned components additional elements, levers, Bowden cables, buffer elements and the like, here will be limited to the following configuration of the multi-ratchet mechanism.
  • the rotary latch is used in particular for secure fixing of a lock holder in a motor vehicle door. It is known to secure the catch already in a position between the open position and closed position, so that a Release of the lock holder is not possible, the so-called pre-locking position. If the catch has reached its desired position in the closed position, it is secured by the so-called main catch. Pre-rest and main rest are regularly provided on the surface or the peripheral surface of the catch locking surfaces.
  • the rotary latch, the first pawl, the second pawl, the blocking lever and the release lever have a metallic base body and are stamped components.
  • the first pawl and the second pawl are also rotatably mounted on a common first pawl rotation axis, which may optionally be biased by a spring.
  • the first pawl serves to lock the catch in the main catch (main catch pawl) and the second pawl serves to lock the catch to the latch (pre-catch pawl).
  • the engagement between the first pawl and the rotary latch is such that the first pawl does not block the catch itself or not alone. Rather, the engagement between the first pawl and the rotary latch is such that the rotary latch exerts a force on the first pawl, so that it is moved into a position releasing the rotary latch.
  • a pivoting of the first pawl with the blocking lever is suppressed, which presses or holds the first pawl against the rotary latch or main catch . If an opening process is now to be initiated, the blocking lever must first be lifted off the first pawl, so that it can be pushed away from the catch itself.
  • a release lever is provided, with which the blocking lever can be pivoted in the initiation of the ⁇ frhungsvorgangs.
  • the first pawl, the second pawl and at least the locking lever are designed as a pivot lever, that is, these can be pivoted (in a limited pivoting range) about its axis.
  • a pivot lever that is, these can be pivoted (in a limited pivoting range) about its axis.
  • the blocking lever or trip lever is arranged such that the blocking lever is also pivoted in this clockwise direction. This can be achieved, in particular, that the blocking lever can be removed after a short Verschwenkweg from the pivoting range of the first pawl, so that here with very small movements, the desired release of the catch can be achieved.
  • the release lever pivots the second pawl during the opening process.
  • the pivoting of the second pawl with the release lever can take place at the same time as pivoting of the blocking lever or possibly delayed in time.
  • the release lever may have a plurality of legs which lie directly and / or are positioned with a clearance to the blocking lever or the second pawl in the closed position in the lock unit.
  • the release lever pivots the blocking lever and the second pawl with the same direction of rotation simultaneously. In this way, a particularly space-saving arrangement of the two pawls, the blocking lever and the release lever can be achieved, for example, by the release lever between the pawls and the blocking lever is arranged.
  • the release lever is rotatable about a trigger lever axis.
  • the release lever is also designed as a pivotable lever. In order to achieve again a particularly space-saving arrangement of the various levers, this pivots with a direction of rotation, which is opposite to the direction of rotation of the first pawl and the blocking lever (and the second pawl).
  • the second pawl is contacted with a counter to its direction of rotation during the opening operation acting return spring.
  • the return spring thus acts on the second pawl in such a way that it is pressed permanently towards the rotary latch and thus a secure attachment to an external stop and / or the rotary latch is realized.
  • the return spring is preferably mounted on the basis of the second pawl opposite to the rotary latch.
  • a motor vehicle which has at least one lock unit described here according to the invention.
  • a lock unit is provided, in particular for locking doors and / or flaps of such motor vehicles.
  • FIG. 1 shows a first embodiment of a lock unit according to the invention in the locked state
  • 2 shows a variant of the lock unit when the first pawl is in engagement with the main catch on the rotary latch
  • Fig. 3 the embodiment of Figure 2, wherein the second pawl is engaged with the pre-catch of the rotary latch.
  • FIG. 4 shows the embodiment variant from FIGS. 2 and 3 in the open position.
  • FIG. 1 schematically indicates a motor vehicle 2 with a door 19 on which a lock unit 1 according to the invention is provided.
  • the lock unit 1 is preferably arranged in a housing 16, on which an inlet mouth 17 is provided for the lock holder 15 arranged on the bodywork of the motor vehicle 2.
  • Fig. 1 shows the locked state of the lock unit 1, wherein the rotary latch 3 has the indicated lock holder 15 securely received in the receptacle 18 provided therefor.
  • the rotary latch 3 is designed with a main catch 5 and a pre-latching 4.
  • two pawls are now provided, both of which are rotatably mounted on the first pawl axis 7.
  • Good to see from above is the second pawl 8, which has no contact to the rotary latch 3 in this locked state.
  • the rotary latch 3 exerts a force on the first pawl 6. This force results on the one hand from the spring preload, which moves the rotary latch 3 in the opening device (white arrow), as well as a force on the lock holder 15 and the door seals acting between the door 19 and the body of the motor vehicle 2, which are compressed here.
  • a blocking lever 9 is provided with a blocking lever axis 10. The first pawl axis and the blocking lever axis are arranged away from each other.
