Abstract: The invention relates to a battery retaining device, comprising a guide device which is designed to receive a vehicle battery; at least one retaining element which is designed to rigidly retain a vehicle battery received in the guide device in a mechanical manner up to a first maximum retaining force value in a first operating state and to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a second maximum retaining force value in a second operating state; and an actuator system with at least one actuator which is designed to bring the at least one retaining element from the first operating state to the second operating state.

Abstract: A crash structure for absorbing crash energy is provided for installation in a vehicle front, in which an actuating system is provided which sets a rigidity of the crash structure as a function of a signal characterizing a crash. Furthermore, the crash structure has a sensor system which outputs this signal. Moreover, the crash structure has two modules that are connected to each other, the connection breaking as of a predetermined force, so that then the at least two modules move with respect to each other, until at least one stop has been reached. The signal indicates the breaking and the reaching of the stop.
