Abstract: The invention relates to a motor vehicle device including a one-piece fastening system of the motor vehicle. This fastening system includes a fastening flange, a guiding member having at least one supporting member and a supporting surface participating in maintaining the guiding member in a first position, and an elastically deformable portion exerting a restoring force adapted to restore the guiding member into said first position.

Abstract: An aerodynamic blade for a motor vehicle includes a shutter mounted on a support shaft having an axis and connected to a chassis of a vehicle by at least one support, and driven in rotation around said axis between an open position and a closed position by a motor assembly. The motor assembly includes one or more elements configured to accumulate mechanical energy and having an adjustable stored energy level to meet a demand for a sufficient torque to change a position of the shutter in a time of less than one second.

Abstract: The invention relates to an aerodynamic deflector arranged at the front of a motor vehicle with a deformable skin of which an upper strip is rigidly connected to the lower portion of a front bumper, and of which a lower strip is connected to a front edge of a rigid arch that can be moved by a manoeuvring device between a low position in which the deformable skin is deployed so as to divert the flow of air that presents under the vehicle when the vehicle advances, and a high position in which the deformable skin is folded away in a recess arranged behind the bumper.

Abstract: A device for maneuvering one or more sets of flaps formed of one or more flaps, each flap pivoting about an axis of rotation (a1a1?, b1b1?, c1c1?, d1d1?, a2a2?, b2b2?, c2c2?, d2d2?) mounted on a chassis. The flaps of a set of flaps are set in rotation by at least one activating plate that moves in translation between two end positions in a main direction (YY?) substantially perpendicular to the axes of the flaps, the activating plate having guide slots, each of the guide slots engaging with a finger disposed on a set of link rods mounted on an upper edge and/or lower edge of each of the flaps of the set, such that movement of the activating plate between the end positions in one direction and in an opposite direction causes each of the flaps of the set of flaps to open and close, respectively.

Abstract: A disengaging member for releasing a link between a motor and a shaft rotated by the motor, the disengaging member including first and second elements capable of fitting together in a direction substantially parallel to the shaft, one element being capable of being connected to the motor by a link that enables the element to be rotated by the motor, and the other element being capable of being attached to the shaft. The first element includes at least one recess at the fitting interface between the two elements, the second element includes at least one resilient member exerting a radial force on the fitting interface via an insertion member capable of being inserted into the recess, keeping the two elements secured to one another for rotation therewith up until a predefined transmission torque between the insertion member and the first element.
