Abstract: The invention relates to an aerodynamic deflector device (7) for a motor vehicle wheel, including: a mounting (11) configured to be mounted on a motor vehicle; a deflecting wall (15) mounted on the mounting (11) so as to be movable between a retracted position in which, in the mounted state, said deflecting wall (15) is raised relative to the mounting (11), and an extended position in which, in the mounted state, said deflecting wall (15) is lowered relative to the mounting (11) and capable of being placed upstream from the wheel (3) of the vehicle; and an actuator (19) configured to move said deflecting wall (15) between the retracted and extended positions. According to the invention, the deflecting wall (15) has, in cross-section, a central portion (15A) and two side portions (15B, 15C) flaring out from the central portion (15A) so as to obtain a shape which diverges with respect to the direction of the air flow (10) striking said wall (15).

Abstract: The invention relates to an aerodynamic deflector device (7) for a wheel of a motor vehicle, comprising: a long support (11) designed to be mounted on a motor vehicle; a deflecting wall (15) mounted such that it is movable on a support (11) between a retracted position in which said deflecting wall (15) is raised in relation to the support (11) in the mounted state, and a deployed position in which said deflecting wall (15) is lowered in relation to the support (11) in the mounted state; and an actuator (19) designed to move said deflecting wall (15) between the retracted and deployed positions. According to the invention, the deflecting wall (15) is mounted such that it can be rotatably moved on the support (11) about an axis of rotation (17) oriented substantially parallel to a longitudinal axis of the support (11) and driven by the actuator (19).

Abstract: The invention relates to an air inflow control system for an active grille shutter, comprising: a frame (101) comprising at least one recess (104, 107); a louvre (102, 106) having a louvre rotary shaft, said louvre rotary shaft being designed to be installed in the recess (104, 107), whereby the louvre can be rotated about the rotary shaft and placed in an open position and a closed position; and a mechanical part (201) adapted to maintain the rotary shaft in the recess (104, 107) when the mechanical part (201) is secured to the frame (101). The mechanical part (201) comprises a stop element (202, 203), said louvre (102, 106) being positioned against the stop element when the louvre (102, 106) is in the open position.
