Abstract (en)

[origin: WO2018172675A1] An aerodynamic blade (1) for a motor vehicle, comprising a shutter (10) mounted on a support shaft (27) of axis XX' linked to a chassis of the vehicle by at least one bearing (270), and rotated about said axis between an open position and a closed position by a motor assembly (2) characterised in that said motor assembly (2) comprises mechanical energy storage means (20) of which the level of stored energy can be adjusted to deliver, on request, sufficient torque for the shutter (10) to change position almost instantaneously in a time of less than 1 second.
