Abstract
The invention is directed to a motor vehicle lock, wherein a lock latch and a pawl, which is assigned to the lock latch, are provided, wherein a crash blocking arrangement is provided for blocking the deflection of the pawl from the engagement position into the release position, when the actuation movement of the pawl actuation lever surpasses a rapidity threshold and wherein a preliminary latch suppressing arrangement is provided for preventing the pawl from falling towards or into the engagement position at the preliminary latching detent during a closing cycle.

A motor vehicle lock, wherein a lock latch and a pawl, which is assigned to the lock latch, are provided, wherein the lock latch can be brought into an open position, into a preliminary latching position and into a main latching position, wherein the lock latch, when in one of the latching positions, is or may be brought into holding engagement with a lock striker, wherein a closing cycle of the motor vehicle lock comprises moving the lock latch from the open position via the preliminary latching position to the main latching position, wherein the pawl may fall into at least one engagement position, in which it is in blocking engagement with a preliminary latching detent or a main latching detent of the lock latch for blocking the lock latch in its preliminary latching position or its main latching position, wherein the pawl may be deflected into at least one release position, in which it releases the lock latch, wherein a pawl actuation lever is provided for deflecting the pawl into the release position, wherein a crash blocking arrangement is provided for blocking the deflection of the pawl from the engagement position into the release position, when the actuation movement of the pawl actuation lever surpasses a rapidity threshold, wherein a preliminary latch suppressing arrangement is provided for preventing the pawl from falling towards or into the engagement position at the preliminary latching detent during a closing cycle.
A method for operating a motor vehicle lock, wherein the motor vehicle lock comprises a lock latch and a pawl, which is assigned to the lock latch, wherein the lock latch can be brought into an open position, into a preliminary latching position and into a main latching position, wherein the lock latch, when in one of the latching positions, is or may be brought into holding engagement with a lock striker, wherein a closing cycle of the motor vehicle lock comprises moving the lock latch from the open position via the preliminary latching position to the main latching position, wherein the pawl may fall into at least one engagement position, in which it is in blocking engagement with a preliminary latching detent or a main latching detent of the lock latch for blocking the lock latch in its preliminary latching position or its main latching position, wherein the pawl may be deflected into at least one release position, in which it releases the lock latch, wherein a pawl actuation lever is provided for deflecting the pawl into the release position, wherein the deflection of the pawl from the engagement position into the release position is being blocked by a crash blocking arrangement, when the actuation movement of the pawl actuation lever surpasses a rapidity threshold, wherein the pawl is being prevented from falling towards or into the engagement position at the preliminary latching detent during a closing cycle by a preliminary latch suppressing arrangement.
