Definitions

  • the invention relates to a lock for a motor vehicle according to the preamble of claim 1.
  • a lock for a motor vehicle comprises a locking mechanism with a rotatably mounted rotary catch for receiving a locking bolt, which is also called a lock holder.

  • Einl ufschlitz also called inlet mouth
  • the locking pin or lock holder then rotates the catch from an opening position to the closed position until the pawl locks the catch. This position is called detent position.
  • the locking bolt can then not leave the inlet slot of the rotary latch.
  • a lock may comprise a blocking lever capable of blocking the pawl in its detent position.
  • the blockage lever must be swiveled out of its blocking position or turned out so that the pawl can leave the latching position for opening the ratchet.
  • iBestHenceistskopie There are motor vehicle locks with two detent positions, namely a pre-detent position and a main detent position.
  • the pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing. If the rotary latch is rotated further starting from the pre-latching position, this finally reaches the main latching position.
  • a lock basically has a release lever that is operated to open or unlatch a ratchet.

If the release lever is actuated, the blockage lever is thereby moved out of its blocking position when the release lever is not excessively accelerated. If excessively high accelerations of the release lever occur, as can be caused by a crash, then blocking the shock prevents the release lever from moving the blocking lever out of its blocking position. Therefore, the lock can not open if the release lever in the event of a crash is accelerated accordingly strong.

  • the Vorrastsperrklin ke 5 at the same time represents the release lever of the castle da r. If the release lever 5 is turned U clockwise and thus actuated, then a projection 10 of the pre-ratchet pawl 5 engages a driver 11 of the blocking lever 7 and thus turns the blocking lever 7 out of its blocking position when the pre-ratchet pawl 5 resp Tripping lever 5 is not excessively accelerated.

This ensures that the functionality of the anti-rotation device is coupled to the locking device already explained, so that improved opening of the locking mechanism can be prevented in the event of an excessive acceleration, in particular in the event of a crash.
  • the locking device preferably corresponds to the above described in connection with the figures 1 to 4 locking device, so that may be referenced in full extent to the above statements. As can further be seen from the illustration in FIG.
  • the anti-twist device is particularly advantageously designed such that the blocking lever 7 rests against the pawl 4 in the position locked by the anti-rotation lock with a sufficiently large blocking contour section 32.
  • the portion of the blocking contour portion 32 which is engageable with the pawl 4 at least a quarter, more preferably at least half of the contour portion 32. This ensures sufficient coverage of the engaging elements, so that the locking generally improved is protected against impulses or shocks, in particular in the event of a crash.
  • the rotation can be useful with the above-mentioned locking device formed as part of a castle. All above-mentioned embodiments of the locking device therefore apply correspondingly in regard to the proposed anti-twist device and a lock designed for a motor vehicle.

Abstract

L'invention concerne une serrure, en particulier pour une porte ou un volet d'un véhicule à moteur. L'objectif de l'invention est d'éviter une ouverture intempestive de la serrure en cas de collision. A cet effet, la serrure selon l'invention présente un dispositif de verrouillage comprenant un pêne pivotant (2), un cliquet (4) pour le verrouillage du pêne pivotant dans une position de verrouillage, de préférence un levier de blocage (7) destiné à bloquer le cliquet dans sa position de verrouillage et un levier de déclenchement (5) servant à ouvrir le dispositif de verrouillage notamment par soulèvement du levier de blocage de sa position de blocage, ladite serrure comportant un élément anti-rotation permettant d'empêcher ou de bloquer une ouverture du dispositif de verrouillage provoquée par un choc ou une impulsion.
