  • the lock cooperating with the lock is located on the stationary bodywork part could be realized in the opposite way.
  • DE 103 12 093 A shows a closure which is intended to block the motor for the electric opening of the trap via a latching lever, as a result of which the engine switches off. This occurs when the door is frozen and the latch can not be rotated to its open position due to its spring load to release the latched part that has been detected.
  • the latching lever has in addition to a decisive for the blockage of the motor stop arm nor a latching arm which is supported in a blockage case of a cranking of the pawl and finally a Aushebearm, which cooperates with a control cam of the case when it moves from its detent position to an open position , This open position is achieved by a manual opening of the flap, in which solves the frozen trap.
  • the invention has for its object to develop a closure of the type mentioned in the preamble of claim 1, which reliably eliminates these closing difficulties. This is inventively achieved by the measures specified in claim 1, which have the following special significance.
  • the rotatable latch provides a mitfitbare retaining shoulder and / or a control cam that when closing the flap is contacted before reaching the locking position the pawl.
  • a radial distance is provided between the latching latch and the pawl counter latching, but if the latch 10 is further rotated beyond the latching position as far as an overhanging position on further closing of the flapper , then this contact phase is terminated and it begins a targeted leadership of the pawl counter-detent with respect to the latch of the catch. This process will be briefly referred to as the "closing phase" of the movement between the latch and the pawl.
  • the trap contour therefore has the new function of bringing the pawl into safe engagement with the trap. To malfunction when closing the flap, which is equipped with the closure according to the invention, so it can not come. Further measures and advantages of the invention will become apparent from the dependent claims and the drawings. In the drawings, the invention is illustrated in three embodiments. Show it:
  • FIG. 1 shows a first embodiment of the invention, where a latch in a pre-locking position and the associated pawl are in a contact phase position
  • Fig. 2 shows the closure of Fig. 1, when the trap is in a

  • FIG. 4 shows the closure already shown in FIG. 3 when the trap is in its overstroke position 0.4 and the pawl is in its final phase position
  • Fig. 5 shows a third embodiment of the invention
  • FIG. 6 shows the third embodiment shown in FIG. 5 in a further operating phase, in which the case is in an overstroke position and the pawl is in its final phase position
  • FIG 7 shows a further phase of operation of the third shown in FIGS. 5 and 6
  • the lock consists of a rotatable latch 10, which is accommodated on a stationary pivot bearing 15 and a spring-loaded pawl 20 which is pivotable on a stationary bearing 25.
  • the latch 10 not only has the catch 12 mentioned in claim 1, which in the three embodiments is a so-called "main catch", but also an upstream latch 1 1, which only partially closes the tailgate Main catch 12.
  • the preliminary catch 11 and the main catch 12 cooperate with a counter catch 21 of the latch 20.
  • the trap 10 When the flap is opened, the trap 10 assumes a so-called "open position", which is not shown in any more detail in the drawings. This open position of the trap 10 is determined by end stops and a spring load 14. If the flap is closed, starting from the open position Thus, moved in the direction of the stationary body part, the closing part 50 moves into a receptacle 13 of the case 10 and exerts a torque on the case 10, which is opposite to their spring load 14.
  • a Vorrastlage 10.1 of the case 10 is shown, but it is crucial that even then the pawl 20 comes into contact with a support point 42 formed as a lever 40 intermediate member.

  • the crease shoulder 30 and the control cam 3 1 are an integral part of the case 10.
  • the cam 3 1 and the retaining shoulder 30 on the case 10 cooperate with a counter-control point 41, which is an integral part of the lever 40.
  • the components 3 1, 30, 41 have the task, in the recognizable from Fig. 2 Kochhublage 1 0.4 the above Contact phase between the pawl 20 and the lever 40 to end. Due to the compressed seals between the case and body, there is a reverse rotation of the case 10, where the closing member 50 moves in the direction of the arrow 52 of Fig.

  • the signals of the sensor 46 are forwarded via a signal line 55 to an electrical control unit not shown in detail.
  • This sensor 46 can determine the relevant positions of the intermediate member 40 and thus the pawl 20, evaluate and / or display. Thus, it can be clearly determined whether the pawl is in its contact phase position 20.1 of FIG. 1 or the final phase position 20.2 of FIG.
  • the elements of the lock components do not interfere with each other, the retaining shoulder 30 and / or the control cam 31 is disposed on the case 1 0 in a different plane than its contour 16 and its two notches 1 1, 12.
  • the counter-control surface 41 is arranged by the lever 40.

Abstract

La fermeture selon l’invention est constituée d'une serrure et d'une pièce de fermeture (50). La serrure comprend un loquet rotatif (10) et un cliquet (20) sollicité élastiquement. Le loquet (10) présente au moins un encliquetage (12) et le cliquet (20) un contre-encliquetage (21). Partant de la position d'ouverture, lorsque le capot est fermé, le loquet (10) est amené dans une position d'encliquetage par l'intermédiaire de la pièce de fermeture (50). Pour que l'encliquetage (12) s’engage de manière fiable dans un encliquetage complémentaire (21) correspondant du cliquet (20), on propose selon l'invention de doter le loquet rotatif (10) d'un épaulement de maintien (30) entraîné conjointement en rotation et/ou d'une came (31) qui, lors de la fermeture du coffre, entre(nt) en contact direct ou indirect avec le cliquet (20) avant que la position d'encliquetage soit atteinte et maintien(nen)t le cliquet transitoirement dans une phase de contact (20.1) définie. Dans cette phase de contact (20.1), il existe un écart entre l'encliquetage (12) du loquet et l'encliquetage complémentaire (21) du cliquet. Il s'établit alors une phase de fermeture dans laquelle le loquet se déplace. Le loquet (10) est ramené en rotation en direction de sa position d'encliquetage par des forces élastiques de rappel. L'encliquetage (12) et l'encliquetage complémentaire (21) s'engagent l'un dans l'autre de manière fiable.
