Definitions

  • the present invention relates to latch assemblies and in particular to latch assemblies for releasably securing vehicle doors when such doors are in a closed position.
  • a typical vehicle door latch mechanism essentially comprises a rotatable claw mounted on the vehicle door which co-operates with a striker pin mounted on the vehicle body.
  • the action of closing the door causes the claw to rotate to a closed position whereupon it engages and retains the striker pin.
  • the claw is maintained in the closed position by a sprung pawl which abuts an appropriately shaped portion of the claw.
  • forces experienced by the latch mechanism can lead to relative movement between the claw and pawl, with the result that the two become misaligned and the pawl no longer maintains the claw in the closed position.
  • the mechanism 10 includes a pawl 12, a latch bolt in the form of a claw 14, and a retention plate 16.
  • the pawl 12 is pivotally mounted via a pawl pivot 20 which is connected to the retention plate 16.
  • the pawl pivot 20 is defined by a pin extending from the retention plate 16.
  • the pawl 12 includes a pawl engagement portion 22.
  • the retention plate 16 in conjunction with further components of the latch mechanism 10 (not shown) which do not move relative to the retention plate 16 during use, form a chassis of the latch mechanism.
  • the claw jaw 26 releasably secures a striker 34 in the mouth 32 of the retention plate 16.
  • the claw 14 can be secured in its closed position, as shown in figure 1, by the pawl 12, and in particular by abutment of the pawl engagement portion 22 with the claw closed engagement portion 28.
  • the striker 34 comprises a pin 36 having at opposite ends thereof a base 38 and an end flange 40. In use, the base 38 of the striker 34 is secured at a location of a vehicle body.
  • the latch mechanism 10 is provided with a substantially planar striker engagement plate 42 within the chassis of the latch mechanism.
  • the striker engagement plate 42 is positioned in the chassis such that it lies on the respective second sides 12B,14B of the pawl 12 and claw 14.
  • striker engagement plate 42 is arranged substantially parallel to the retention plate 16 and may be carried by the pins defining the pawl and claw pivots 20,24.
  • the claw jaw 26 releasably secures the striker 34 both in the mouth 32 of the retention plate 16 and a corresponding mouth 44 of the striker engagement plate 42.
  • the striker engagement plate 42 is positioned between the claw 12 and pawl 14 and the end flange of the 40 of the striker 34. Under the abnormal conditions described above, the striker engagement plate 42 acts to resist misalignment of the pawl 12 and claw 14.
  • Movement of the claw 12 and/or pawl 14 can result in each or either of them moving into contact with the retention plate 16 and/or the striker engagement plate 42, with the plates 16,42 then acting to constrain further movement of the claw 12 and/or pawl 14.
  • the proximity of the striker engagement plate 42 to the striker end flange 40 means that any distortion or flexing of the striker engagement plate 42 causes it to abut the end flange 40. Further distortion or flexing of the striker engagement plate 42 is resisted by the end flange 40.

Claims (8)

  1. Schließmechanismus (10) mit einem Schließbolzen (14) zum lösbaren Befestigen eines Anschlags (34) in einer geschlossenen Stellung, wobei der Schließbolzen auf einem Gehäuse des Schließmechanismus beweglich angebracht ist, und mit einer Klinke, die auf dem Gehäuse beweglich angebracht ist und mit dem Schließbolzen in Eingriff gebracht werden kann, um ihn in einer geschlossenen Stellung lösbar zu befestigen, wobei der Schließmechanismus ferner ein in dem Gehäuse angebrachtes Begrenzungselement (42) umfasst, wobei das Begrenzungselement angrenzend an die Klinke und den Schließbolzen positioniert ist, dadurch gekennzeichnet, dass dann, wenn der Anschlag in der geschlossenen Stellung befestigt ist, nachdem der Schließmechanismus mit einer abnormen Kraft beaufschlagt wurde, das Begrenzungselement eine Relativbewegung zwischen dem Schließbolzen und der Klinke durch das Zusammenwirken mit einem Eingriffsabschnitt (40) des Anschlags begrenzt.
  2. Schließmechanismus nach Anspruch 1, bei dem das Gehäuse eine Halteplatte (16) aufweist, die auf einer ersten Seite (12A, 14A) der Klinke und des Schließbolzens liegt und eine Öffnung (32) zur Aufnahme des Anschlags aufweist, wobei das Begrenzungselement in dem Gehäuse auf einer zweiten Seite (12B, 14B) der Klinke und des Schließbolzens liegt, so dass sich die Klinke und der Schließbolzen zwischen der Halteplatte und dem Begrenzungselement befinden.
  3. Schließmechanismus nach einem der vorhergehenden Ansprüche, bei dem das Begrenzungselement mit einer Öffnung (44) zur Aufnahme des Anschlags versehen ist.
  4. Schließmechanismus nach Anspruch 3, bei dem der Eingriffsabschnitt des Anschlags größer ist als die Öffnung des Begrenzungselements.
  5. Schließmechanismus nach Anspruch 4, bei dem der Eingriffsabschnitt durch einen Flansch (40) des Anschlags gebildet wird.
  6. Schließmechanismus nach Anspruch 5, bei dem das Begrenzungselement zwischen den zweiten Seiten der Klinke und des Schließbolzens und dem Flansch des Anschlags positioniert ist, wenn der Anschlag in der geschlossenen Stellung befestigt ist.
  7. Schließmechanismus nach einem der vorhergehenden Ansprüche, bei dem das Gehäuse Stifte umfasst, um die die Klinke und der Schließbolzen beweglich angebracht sind, wobei das Begrenzungselement auf den Stiften angeordnet ist.
  8. Schließmechanismus nach einem der vorhergehenden Ansprüche, wobei das Begrenzungselement im Wesentlichen eben ist.
