Abstract: A motor vehicle has a rear seat bench, a storage compartment arranged behind the rear seat bench in the direction of travel, and a storage compartment floor. A hat shelf is positionable behind the rear seat bench in a usage position such that it separates a passenger compartment from the storage compartment. In order to thereby provide an easily actuatable hat shelf which is also sturdy when in its non-usage position in the motor vehicle, a gap is provided between the rear seat bench and the storage compartment floor. The hat shelf and the gap interact such that the hat shelf can be inserted into the gap in a non-usage position and can be fixed to the rear seat bench via a fixation device such that, in its non-usage position, the hat shelf adjoins a rear side of the rear seat bench.
