Motor vehicle lock

The invention is directed to a Motor vehicle lock for a motor vehicle door arrangement (2), wherein a catch (3) and a pawl (4), which is assigned to the catch (3), are provided, wherein the catch (3) can be brought into an open position and into a closed position, wherein the catch (3), which is in the closed position, is or may be brought into holding engagement with a lock striker (5), wherein the pawl (4) may be brought into an engagement position, in which it is in blocking engagement with the catch (3) and wherein the pawl (4) may be deflected into a release position, in which it releases the catch (3), wherein a lock mechanism (6) is provided, which may be brought into different functional states such as "unlocked" and "locked" via a lock actuation arrangement (7) and wherein a pawl actuation arrangement (8) is provided, by which actuation the pawl (4) may deflected into the release position depending on the functional state of the lock mechanism (6), wherein a crash mechanism (9) with a crash element (9a) is provided, which crash mechanism (9) may be brought from a normal condition into a crash condition by engagement with a component (10) of the motor vehicle door arrangement (2), in particular a door body shell (11), which component (10) is being deformed due to a crash. It is proposed that a switchable coupling (12) is provided between the pawl actuation arrangement (8) and the pawl (4) and that the crash element (9a) is acting on the switchable coupling (12) or is part of the switchable coupling (12) in such a way that bringing the crash mechanism (9) into the crash condition opens the switchable coupling (12) and therewith lets an actuation of the pawl actuation arrangement (8) run free.
