Definitions

  • the present invention relates to a motor vehicle lock according to the preamble of claim 1.
  • the motor vehicle lock in question finds application in all types of closure elements of a motor vehicle. These include in particular side doors, rear doors, tailgates, trunk lids or hoods. In principle, these closure elements can also be designed in the manner of sliding doors.
  • the known motor vehicle lock ( DE 102 58 645 B4 ), from which the invention proceeds, shows a motor vehicle lock with a latch, which can be brought into an open position, in a main closed position and in a Vorschstedwolf.
  • the latch is associated with a locking element in the manner of a pawl, which holds the latch in the two closed positions. To release the latch, the locking element can be transferred from a blocking position to a release position.
  • the invention is based on the problem, the known motor vehicle lock in such a way and further develop that the design effort is simplified while reducing weight.
  • the blocking element which provides a force-transmitting component of the force action chain for holding the closure element, is designed as a resilient bendable wire or strip and is bendable between the blocking position and the release position.
  • the blocking element configured as a wire or strip can be realized with particularly low weight. It is even conceivable to design the blocking element made of plastic in order to further reduce the weight.
  • the advantageous variant according to claim 15 exploits the elastic flexibility of the blocking element in so far as only a part of the engagement arrangement and / or only a part of the support arrangement is in engagement with the blocking element for blocking the latch in normal operation. Only in the event of a crash does it come to a full-scale intervention in that due to the then possibly occurring, high blocking forces a certain bending of the locking element takes place. This can be ensured that in normal operation, a contacting of the blocking element takes place only to a small extent.
  • the proposed motor vehicle lock is equipped in a conventional manner with a latch 1.
  • the motor vehicle lock is associated in a likewise conventional manner a closing wedge 2 or the like, which can be brought into holding engagement with the latch 1.
  • the closing wedge 2 may also be a locking bolt or a closing bolt.
  • the proposed motor vehicle lock also has a blocking element 3, which can be brought into a blocking position and into a release position.
  • the blocking position is in the drawing in a solid line
  • the release position is shown in the drawing in dashed lines.
  • the blocking element 3 located in the blocking position is blockingly engaged with the locking latch 1 located in the closed position, while the locking element 3 located in the release position releases the latch 1 for adjustment into the open position.
  • the latch 1 is engageable in the illustrated closed position and in an open position. From the illustration in Fig. 1 the opening position of the latch 1 results by a pivoting of the latch 1 to the lock latch axis 1a right around.
  • the latch 1 extends substantially in a latch level 4, which is aligned perpendicular to the latch axis 1a.
  • the latch bolt 1 can be brought into a single closed position. It is also conceivable that the latch bolt 1 can be brought, on the one hand, into a prelocking position and, on the other hand, into a main closed position.
  • the locking element 3 is designed as a resilient bendable wire or strip and is bendable in the blocking position and in the release position accordingly. It can be the representation in Fig. 1 remove, that the adjustment of the locking element 3 is here due to a resilient bending of the same.
  • the blocking element 3 consists of a metal material, preferably spring steel.
  • the locking element 3 may be configured in particular as a blank, drawn steel wire.
  • a coating of the blocking element 3 for reducing the friction with the engagement and support elements 7a-c, 8a-c. But it may also be advantageous to design the blocking element 3 made of plastic.
  • the blocking element 3 has a circular cross-section.
  • the blocking element 3 is designed strip-shaped or strip-shaped, since such elements can be fastened in a simple manner.
  • the blocking element 3 is partially configured straight. Depending on the application, it may also be advantageous that the blocking element 3 is adapted to the structural conditions and deviates significantly from a straight configuration.
  • the blocking element 3 is formed as a one-piece wire, which has the same spring-elastic properties over its entire length.
  • the blocking element 3 is resiliently bendable only in sections and, moreover, rather rigidly configured. This can be achieved, for example, by changing the wire cross-section over the length of the wire.
  • the blocking element 3 is fixed at one end and the other end deflected to adjust the blocking position and the release position.
  • the blocking element 3 effectively forms a bending beam.
  • the term "fixed” is to be understood here broadly. This corresponds to the illustrated embodiment, in which the locking element 3 is wound around the lock latch axis 1a for fixing. The associated advantage will be explained below.
  • the orientation of the locking element 3 and the adjustment of the locking element 3 is of particular importance in the present case.
  • the blocking element 3 is substantially bendable about a geometric bending axis 5, which is aligned substantially perpendicular to the latch axis 1a. This also leads to a particularly compact design, since the locking element 3 located in the blocking position can be arranged in the lock case plane 4 without further ado.
  • blocking element 3 located in the blocking position transmitting a blocking force B to the latch 1 in at least one engagement region 6 of the blocking element 3 and that the blocking force B is aligned substantially perpendicular to the extent of the blocking element 3 in the engagement region 6 ,
  • the blocking force B to be transmitted thus leads primarily to shear forces in the blocking element 3.
  • a particularly compact embodiment results in the embodiment shown also in that the locking element 3 extends at least in one of its positions substantially perpendicular to the latch axis 1a. This can be provided at least in sections. In this case, and preferably, the blocking element 3 in any case extends in the engagement region 6 essentially perpendicular to the latch axis 1a.
  • the blocking element 3 is located at least in sections, here and preferably in any case in the engagement region 6, substantially in the lock case plane 4.
  • substantially in the lock case plane 4" is meant here that the locking element 3 seen perpendicular to the lock catch axis 1a extends at least along the lock latch 1.
  • the latch 1 is equipped with an engagement arrangement 7, which is blocking in locking position 3 in the engagement region 6, the latch 1 blocking, with the locking element 3 is engaged or can be brought.
  • the engagement arrangement 7 comprises at least one engagement element 7a.
  • a plurality of engagement elements 7a-c here a total of three engagement elements 7a-c, are provided. These multiple engagement elements 7a-c are then arranged distributed along the locking element 3 in the closed position located in the lock latch 1. This makes it possible to achieve an optimal distribution of the blocking force B.
  • a support arrangement 8 is provided here and preferably.
  • the support assembly 8 is located in the blocking position locking element 3 is supported for blocking the latch 1 in the closed position.
  • the support assembly 8 comprises at least one support element 8a-c.
  • the support assembly 8 comprises a plurality of support elements 8a-c, wherein more preferably, the plurality of support elements 8a-c distributed along the locking element 3 are arranged.
  • the support elements 8a-c are arranged on the fishing camp or on the rear plate of the motor vehicle lock.
  • engagement elements 7a-c and / or the support elements 8a-c are each elongated and extend substantially perpendicular to the blocking element 3 at least in the respective engagement region 6 is also interesting in the exemplary embodiment shown and preferred. This information, of course, refers to the latch 1 located in the closed position.
  • the engagement elements 7a-c and the support elements 8a-c in the adjustment of the lock latch 1 from the closed position to the open position pass each other, in particular mesh.
  • the elongated engagement elements 7a-c and / or support elements 8a-c preferably run on a circular arc aligned with the latch axis 1a.
  • a particular closed slide guide 9 is provided, through which the locking element 3 passes.
  • the slide guide 9 is arranged in a wall section or the like of the respective lock housing, which extends substantially parallel to the lock latch axis 1a.
  • the slide guide 9 is configured here and preferably as a slot, which extends correspondingly substantially parallel to the latch axis 1a.
  • the resilient bendable locking element 3 is not only the blocking of the latch 1 in the closed position, but also the bias of the latch 1 in the open position.
  • the blocking element 3 is configured in sections in the manner of a leg spring.
  • the torsion spring-like portion of the locking element 3 has a spring turn 3a and two legs 3b, 3c, wherein the one spring leg 3b is engaged with the lock latch 1 and wherein the other spring leg 3c merges into a straight, the engagement portion 6 having portion of the locking element 3.
  • the slotted guide 9 not only serves to guide the movement of the free end of the locking element 3, but also provides an abutment for the leg 3 c of the above, torsion spring-like portion of the locking element 3.
  • the blocking element 3 can also serve in the context of a sensory position detection for the blocking element 3.
  • two contacts 10 are provided for sensory detection, which are in electrically conductive contact with the locking element 3 located in the blocking position and which are in the release position befindlichem blocking element 3 except for electrical contact of the blocking element 3 ,
  • an electrical switch can be realized which provides information about the position of the blocking element 3. Basically it can but also be provided that the free end of the locking element 3 actuates a micro-switch or the like.
  • a hold-down device for blocking the locking element 3 is preferably further provided in the blocking position.
  • Such a hold-down device can be brought into a safety position, wherein the holding-down device located in the safety position blocks the blocking element 3 in the blocking position. This can be prevented in a simple manner that in the context of a break-in attempt, the blocking element 3, for example, pulled over the inlet mouth of the motor vehicle lock in the release position or pressed.
  • the detailed view shown in the drawing shows a structural feature with which above all a high crash safety can be realized without the ease of use is impaired in particular with regard to the necessary operating force when lifting the locking element 3. It is the case here that during the blocking forces occurring during normal operation, only a part of the engagement arrangement 7 and / or only a part of the support arrangement 8 is in engagement with the blocking element 3 located in the blocking position and that the high blocking forces possibly occurring in the event of a crash Bending of the locking element located in the blocking position 3 effect such that the engagement assembly 7 and the support assembly 8 are fully in engagement with the locking element 3, respectively.
  • the free end of the blocking element 3 could be coupled via a coupling with an external operating lever and / or an internal operating lever or with an outside door handle and / or a door inner handle. It is also conceivable, however, the motor deflection of the free end of the locking element 3 by means of a control drive.
