Claim:
1. A motor vehicle door lock arrangement with a motor vehicle lock, wherein a force transmission chain is provided and wherein an actuation movement may be transmitted via the force transmission chain for opening of the motor vehicle lock, wherein a crash coupling arrangement is provided between two force transmission chain sections, which comprises a coupling element in the form of a coupling spring element, wherein the coupling spring element can be brought into a coupling state, coupling the two force transmission chain sections, and into a decoupling state, decoupling the two force transmission chain sections, wherein the crash coupling arrangement comprises a first link element assigned to one force transmission chain section and a second link element assigned to the other force transmission chain section, wherein, the link elements are moveable along a longitudinal extension of movement, wherein the coupling spring element for coupling the two force transmission chain sections may come into coupling engagement with at least one of the link elements, wherein an inertial characteristic of the coupling spring element causes the coupling spring element to fall into or to remain in the decoupling state, when the actuation movement surpasses a rapidity threshold, and causes the coupling spring element to fall into or to remain in the coupling state, when the actuation movement is below the rapidity threshold, wherein at least one of the link elements, in the area of interaction with the coupling spring element, is at least partly symmetric with respect to the longitudinal extension of movement, such that rotation of this link element against the rest of the crash coupling arrangement around the longitudinal extension of movement does not affect its interaction with the coupling spring element.
