13. An elevator car arrangement for a double-deck elevator, the car arrangement comprising:
an elevator car frame;
a first car coupled to the car frame;
a second car arranged on the car frame above or below the first car and coupled to the car frame, the second car being movable in a vertical direction relative to the car frame and relative to the first car;
a push chain having a force absorption section with a first end and an opposite second end, the first end being coupled to the first car or to the car frame and the second end being coupled to the second car, wherein the second car exerts a pressure load on the force absorption section due to gravity;
a drive device coupled to the push chain, the drive device displacing the second car in the vertical direction relative to the first car through the push chain; and
wherein the drive device has a motor that is driven as a generator by the push chain when the second car is displaced by gravity.
