1. A device for regulating or controlling an air flow in a vehicle compartment, comprising:
at least one wing connectable to an air flow opening of the vehicle compartment and movable between a closed position for closing the air flow opening and an open position for opening the air flow opening;
a drive module configured to apply a predetermined thrust force;
a transmission apparatus adapted to transmit the thrust force from the drive module to the at least one wing to bring the at least one wing at least from the closed position to the open position;
the drive module comprising at least: a first actuator made of a shape-memory alloy configured to apply the thrust force when the first actuator reaches a predetermined temperature, and at a second actuator configured to apply an opposing force to oppose the thrust force;
a slide which is guided in translation in parallel with the thrust force and which is interposed between the first actuator and the second actuator such that the first actuator and the second actuator operate on opposite sides of the slide.
