Claim:
1. A motor vehicle lock for a motor vehicle door arrangement, the motor vehicle lock comprising: a catch and a pawl, which is assigned to the catch, wherein the catch can be brought into an open position and into a closed position, wherein the catch, which is in the closed position, is or may be brought into holding engagement with a lock striker, wherein the pawl may be brought into an engagement position, in which the pawl is in blocking engagement with the catch and wherein the pawl may be deflected into a release position, in which the pawl releases the catch, wherein a lock mechanism is provided, which may be brought into different functional states comprising an “unlocked” state and a “locked” state via a lock actuation arrangement and wherein a pawl actuation arrangement is provided, by which actuation the pawl may be deflected into the release position depending on the functional state of the lock mechanism, wherein a crash mechanism with a crash element is provided, which crash mechanism may be brought from a normal condition into a crash condition by engagement with a component of the motor vehicle door arrangement, which component is being deformed due to a crash, wherein a switchable coupling is provided between the pawl actuation arrangement and the pawl and that the crash element is acting on the switchable coupling or is part of the switchable coupling in such a way that bringing the crash mechanism into the crash condition opens the switchable coupling and therewith lets an actuation of the pawl actuation arrangement run free, wherein the crash mechanism comprises a crash engagement element for engagement of the component of the motor vehicle door arrangement, which component is being deformed by a crash, and wherein the crash engagement element is coupled to the crash element in order to transfer at least part of the crash induced deformation movement to the crash element, wherein the crash engagement element comprises a bow section which at least on two end portions is being supported by a support arrangement, wherein on one end portion the support arrangement is part of a housing component, and wherein at least part of the crash engagement element is provided by a wire or strip which is bent on engagement with the component when the component is being deformed due to the crash.
