Abstract:
A door lock arrangement of a vehicle door of a vehicle includes a first closing element arranged in a lock mouth of the vehicle door and a second closing element arranged on a body of the vehicle. The first and second closing elements can be brought into positive-locking engagement with each other to hold the door on the body. A damping device absorbs kinetic energy of the door during a closing movement of the door within a predetermined limit opening angle of the vehicle door relative to the body and slows down the closing movement of the door. The damping device has an impact element arranged on the door in a displaceable manner relative to the door or on the body in a displaceable manner relative to the body. The impact element is connected to an actuator, which applies a pre-tensioning force of the door directed in an opening direction of the door while the first and second closing elements are engaged with each other.
