Definitions

  • the invention relates to a motor vehicle lock, in particular a motor vehicle hood lock, with a locking mechanism consisting of a rotary latch and at least one pawl, and with a release lever for the pawl, the pawl being equipped with at least a first ratchet tooth and a second ratchet tooth, and wherein the rotary latch has at least one preliminary detent and one main detent.
  • Motor vehicle locks and in particular motor vehicle hood locks are typically used to close a motor vehicle hood or also a motor vehicle flap, for example a motor vehicle front hood or a motor vehicle tailgate.
  • motor vehicle fitters are not restricted to such areas of application.
  • An example of such a motor vehicle lock is described in DE 10 2014201 808 A1 by the applicant.
  • the relevant motor vehicle lock is generally opened with the aid of an actuating device ending in the interior of the associated motor vehicle.
  • This can, for example, work manually via a linkage or a Bowden cable on the release lever and ensure the unlocking or opening of the motor vehicle lock.
  • the actuating device may be a handle or a loop for manual actuation. In principle, however, a switch for the electrical application of the release lever can also be actuated.
  • Motor vehicle hood locks can in principle be opened in this way, but are only opened by spring force and for safety reasons put up a crack. This is necessary in order, for example, to prevent the motor vehicle front hood from being completely swung open if the actuating device is operated incorrectly while driving.
  • the complete opening of the motor vehicle wing from this gap position usually takes place with the aid of a catch lever which, for this purpose, has to be pivoted by an operator while the associated motor vehicle is at a standstill, so that the wing is finally released.
  • the catch lever engages around or over the locking bolt attached to the motor vehicle front hood.
  • the catch lever typically interacts with a locking bolt attached to the front hood of the motor vehicle.
  • the present invention is based on the technical problem of developing such a motor vehicle lock so that in the course of the Unlocking the pre-latching position is safely assumed.
  • a generic motor vehicle lock and in particular a motor vehicle hood lock is characterized within the scope of the invention in that the pawl, with its second ratchet tooth, lifted off the main catch of the rotary latch with its first ratchet tooth with the aid of the release lever for unlocking Rotary latch interacts with the forced guidance of the pawl and blocking the preliminary catch of the rotary latch during the opening process of the locking mechanism.
  • the pawl in order to unlock the motor vehicle lock and safely assume the pre-latching position, the pawl is first lifted off the rotary latch with the aid of the release lever.
  • the first ratchet tooth of the pawl is removed or lifted off the main catch of the rotary latch in detail.
  • the rotary latch is initially free and swivels (spring-assisted) in its opening direction.
  • the main ratchet of the rotary latch can interact with the second ratchet tooth of the pawl.
  • the pawl is forced to operate, which is typically pivoted in the direction of the rotary latch during this process, so that the pawl can properly block the preliminary detent of the rotary latch or interacts with the preliminary detent of the rotary latch during the further opening movement of the rotary latch.
  • the blocking of the preliminary catch of the rotary latch is advantageously carried out with the aid of the first ratchet tooth.
  • the forced guidance of the pawl by the main catch of the rotary latch that swings open in the opening direction ensures that the pawl with its first ratchet tooth is pivoted in the direction of contact with the rotary latch by the main catch of the opening rotary latch moving against the second ratchet tooth of the pawl.
  • the first ratchet can now block the preliminary catch of the opening rotary latch.
  • the positive guidance of the pawl through the interaction with the main notch of the opening rotary latch ensures that the pawl always faces up the rotary latch is pivoted so that the first ratchet tooth interacts with the preliminary catch of the rotary latch during this opening process and the rotary latch is effectively blocked as a result.
  • the first catch of the rotary latch is blocked in the course of unlocking with the aid of the first ratchet tooth of the pawl. This is possible because through the positive guidance of the pawl through the mutual interaction of the second ratchet with the main ratchet, the first ratchet tooth of the ratchet is pivoted in the direction of the rotary latch, so that the opening rotary latch automatically during this process with its preliminary ratchet against the first ratchet in question the pawl moves and is blocked as a result.
  • the preliminary detent and the main detent of the rotary latch are each designed as a preliminary detent tooth or main detent tooth. It is consequently not a pre-locking recess or main locking recess, but rather a pre-locking tooth and a main locking tooth, consequently a tooth-like elevation on the outer circumference of the rotary latch.
  • the rotary latch is usually equipped with a catch arm and a load arm, as is customary for rotary latches in motor vehicle hood locks.
  • the two ratchet teeth are generally arranged adjacent to the load arm on the outer circumference of the rotary latch. As a result of this, the two locking teeth arranged exposed on the outer circumference of the rotary latch can easily interact with the respective locking tooth of the locking pawl as described.
  • the design is advantageously made so that the first ratchet is arranged on the front of the pawl.
  • the second ratchet tooth is arranged such that it is designed as a projection offset in the direction of an axis of the ratchet pawl relative to the first ratchet tooth. That is, starting from the first ratchet tooth on the front side of the ratchet pawl, the second ratchet tooth follows in the direction of the axis of the ratchet pawl, specifically as a projection offset with respect to the first ratchet tooth.
  • the pawl is usually equipped with a stop for interaction with the release lever.
  • the stop is usually a further projection offset on the second ratchet tooth in the direction of the axis.
  • the pawl starts from the first ratchet tooth, the pawl has a stepped design in the direction of its axis such that the first ratchet tooth is followed by the second ratchet tooth as a projection and the stop follows the second ratchet tooth as a further projection.
  • the design is also made such that the stop on the pawl is engaged from behind by a nose of the release lever.
  • a pivoting movement of the release lever in the direction of unlocking or opening the motor vehicle lock means that the mostly radially arranged and extending nose of the release lever engages behind the stop on the pawl and thereby pivots the pawl so that it releases the rotary latch as described.
  • a motor vehicle lock is made available which is particularly suitable as a motor vehicle hood lock and is predestined for this. Because a first actuation of the release lever to unlock the motor vehicle lock in question leads to the locking pawl being positively guided with the help of the rotary latch and the locking mechanism as a whole and as a result of the forced guidance being able to assume the mandatory pre-locking position. Only in the course of a second actuation of the release lever, for example, can the pawl be lifted off the rotary latch so that it is in its entirety the open position.
  • the inevitable pre-locking position can be used, for example, to move the motor vehicle front hood equipped with the motor vehicle lock in question into the gap position already described above, so that the second actuation of the release lever enables the motor vehicle front hood to be completely opened.
  • a double-stroke actuation of the release lever is ultimately required to open the motor vehicle lock.
  • Fig. 1 shows the motor vehicle lock according to the invention in
  • FIGS. 2A to 2C the unlocking of the lock and the forced operation of the
  • a motor vehicle lock which is not restrictively a motor vehicle leaf lock, preferably a motor vehicle front hood lock.
  • This has a locking mechanism 1, 2 consisting of a rotary latch 1 and a pawl 2.
  • the figures show that the rotary latch 1 is equipped with a catch arm 1 a and a load arm 1 b, with an insertion slot between them for one in the figures define only indicated locking bolt 3, which is connected according to the embodiment to the motor vehicle front hood, which is not expressly shown.
  • the basic structure also includes a release lever 4, which, starting from the main detent position in FIG. 1, must be pivoted clockwise about its axis 5 in order to unlock or open the locking mechanism 1, 2, as will be explained in more detail below.
  • the clockwise movement of the release lever 4 about its axis 5 may be brought about by an actuating device 6, indicated only in FIG.
  • the pawl 2 is equipped with at least one first ratchet tooth 2a and a second ratchet tooth 2b.
  • the pawl 2 also has a stop 7.
  • the stop 7 on the pawl 2 is engaged from behind by a nose 8 on the release lever 4.
  • the already mentioned action of the actuating lever 4 around its axis 5 in a clockwise direction causes the actuating lever 4 to move with its nose 8 against the stop 7 of the pawl 2 and this counterclockwise around its during such an unlocking or opening process of the locking mechanism 1, 2 Axis 9 is pivoted, as shown in particular in FIGS. 2A to 2C to be described below.
  • the rotary latch 1 is initially at least partially free and can rotate about its axis 10 in the indicated counterclockwise direction. This is ensured in particular by door rubber sealing forces or other spring forces which are introduced into the rotary latch 1 via the locking bolt 3 and which pretension it about its axis 10 in the counterclockwise direction of the opening movement.
  • the rotary latch 1 is also equipped with a preliminary catch 11 b and a main catch 11 a.
  • the figures show that the preliminary ratchet 11 b as well as the main ratchet 11 a are each ratchet teeth 11 a, 11 b, namely a preliminary ratchet tooth 11 b and a main ratchet tooth 11 a. Besides, they are two ratchet teeth 11 a, 11 b then arranged on the load arm 1 b of the rotary latch 1 on the outer circumference of the rotary latch 1.
  • the design is such that the pawl 2 is lifted off the main detent or main detent tooth 11a of the rotary latch 1 with the aid of the release lever 4 to unlock the locking mechanism 1, 2, with its first locking tooth 2a. That is to say, in the main ratchet position shown in FIG. 1, the first ratchet tooth 2a of the pawl 2 rests on the main ratchet tooth 11a of the rotary latch 1.
  • the first ratchet tooth 2a of the pawl 2 is arranged on the front.
  • the second ratchet 2b of the pawl 2 is designed in the direction of the axis 9 of the pawl 2 as an offset projection with respect to the first ratchet 2a.
