1. A roof lining system for motor vehicles, comprising:
at least one air supply connection for connecting the roof lining system to an air conditioning unit of the motor vehicle;
at least two outflow devices which are in fluid connection with the at least one air supply connection,
wherein the roof lining system is characterized by the following features:
each outflow device has a central outflow region and a peripheral outflow region, each of which has at least one separate air supply channel;
each outflow device has at least two flow actuators, wherein at least one first flow actuator is assigned to the central outflow region, and at least one second flow actuator is assigned to the peripheral outflow region;
the at least one first flow actuator is arranged in the at least one air supply channel of the central outflow region, and the at least one second flow actuator is arranged in the at least one air supply channel of the peripheral outflow region; and
the peripheral outflow region at least partially surrounds the central outflow region;
wherein the peripheral outflow region surrounds the central outflow region over an angular range of more than 180°,
wherein the respective flow actuators can be adjusted independently of each other between a closed position in which the air supply channel in which the flow actuator is arranged is closed by means of the flow actuator, and an open position in which the air supply channel in which the flow actuator is arranged is permeable to air.
