The deflecting wall is mounted such that it can be rotatably moved on the support about an axis of rotation oriented substantially parallel to a longitudinal axis of the support and driven by the actuator. ## Claims ### Claim 1 An aerodynamic deflector device for a motor vehicle wheel, comprising: an elongate support configured to be mounted on a motor vehicle; a deflecting wall mounted on the elongate support so as to be movable between a retracted position in which, in a mounted state, said deflecting wall is raised with respect to the elongate support, and a deployed position in which, in the mounted state, said deflecting wall is lowered with respect to the elongate support; and an actuator configured to move said deflecting wall between the retracted and deployed positions, wherein the deflecting wall is mounted rotatably on the elongate support about an axis of rotation oriented substantially parallel to a longitudinal axis of the elongate support and driven by the actuator. ### Claim 2 (depends on 1) The device as claimed in claim 1, wherein the deflecting wall has, in longitudinal section, a ramp shape. ### Claim 3 (depends on 2) The device as claimed in claim 2, wherein the ramp is curved. ### Claim 4 (depends on 3) The device as claimed in claim 3, wherein the radius of curvature of the curved ramp decreases progressively from a distal end arranged remote from the wheel toward a proximal end arranged in the vicinity of the wheel. ### Claim 5 (depends on 4) The device as claimed in claim 4, wherein the deflecting wall has, at the proximal end arranged in the vicinity of the wheel, in cross section, a “U” shape, the bottom of the “U” being remote from the axis of rotation. ### Claim 6 (depends on 5) The device as claimed in claim 5, wherein said device comprises a closure wall situated at the proximal end of the deflecting wall. ### Claim 7 (depends on 1) The device as claimed in claim 1, wherein the elongate support is produced as a frame of rectangular shape and configured to be fixed to the chassis of a motor vehicle. ### Claim 8 (depends on 1) The device as claimed in claim 1, wherein the actuator comprises a rotary output member in direct or indirect engagement with said axis of rotation. ### Claim 9 (depends on 1) The device as claimed in claim 1, wherein said axis of rotation bearing the deflecting wall is configured to carry out a rotation of 180° between the retracted and deployed positions. ### Claim 10 A motor vehicle, comprising at least one aerodynamic deflector device that is arranged upstream of a vehicle wheel, the aerodynamic deflector device further comprises: an elongate support configured to be mounted on the motor vehicle; a deflecting wall mounted on the elongate support so as to be movable between a retracted position in which, in a mounted state, said deflecting wall is raised with respect to the elongate support, and a deployed position in which, in the mounted state, said deflecting wall is lowered with respect to the elongate support; and an actuator configured to move said deflecting wall between the retracted and deployed positions, wherein the deflecting wall is mounted rotatably on the elongate support about an axis of rotation oriented substantially parallel to a longitudinal axis of the elongate support and driven by the actuator. ### Claim 11 (depends on 10) The motor vehicle as claimed in claim 10, wherein the deflecting wall has, in longitudinal section, a ramp shape. ### Claim 12 (depends on 11) The motor vehicle as claimed in claim 11, wherein the ramp is curved. ### Claim 13 (depends on 12) The motor vehicle as claimed in claim 12, wherein the radius of curvature of the curved ramp decreases progressively from a distal end arranged remote from the wheel toward a proximal end arranged in the vicinity of the wheel. ### Claim 14 (depends on 13) The motor vehicle as claimed in claim 13, wherein the deflecting wall has, at the proximal end arranged in the vicinity of the wheel, in cross section, a “U” shape, the bottom of the “U” being remote from the axis of rotation. ### Claim 15 (depends on 14) The motor vehicle as claimed in claim 14, wherein said device comprises a closure wall situated at the proximal end of the deflecting wall. ### Claim 16 (depends on 10) The motor vehicle as claimed in claim 10, wherein the elongate support is produced as a frame of rectangular shape and configured to be fixed to the chassis of a motor vehicle. ### Claim 17 (depends on 10) The motor vehicle as claimed in claim 10, wherein the actuator comprises a rotary output member in direct or indirect engagement with said axis of rotation. ### Claim 18 (depends on 10) The motor vehicle as claimed in claim 10, wherein said axis of rotation bearing the deflecting wall is configured to carry out a rotation of 180° between the retracted and deployed positions.
