Abstract: A fixing device for releasable fixing an electrical energy accumulator to a carrying structure of a motor vehicle includes a retaining protrusion and a locking catch which are provided on the energy accumulator and on the carrying structure (or vice versa). To fix the energy accumulator to the carrying structure, a relative movement of the retaining protrusion to the locking catch is provided along a movement track in the direction of an end position, in which the locking catch can be swiveled between a release position and a locked position such that in the release position the locking catch is outside the movement track of the retaining protrusion and in the locked position the locking catch protrudes into the movement track of the retaining protrusion and there engages behind the retaining protrusion when the retaining protrusion is in the end position.

Abstract: An actuator, which can be actuated along a longitudinal axis, in particular for a spring carrier, includes a stationary part, a first rotor, which can be driven so as to perform a rotary motion, a rotatable second rotor, which is supported against the stationary part in the axial direction in an axial rest position, a coupling device, by which the second rotor is coupled to the first rotor, and an output element, which is connected to the second rotor and can be moved axially by means of a rotary motion of the second rotor. The coupling device interacts with the first rotor and the second rotor in such a way that, starting from the rest position, an axial movement of the second rotor can be produced by means of a first rotary motion of the first rotor in order to release the second rotor from the stationary part and thereby bring it into a working position.
