Abstract: Device for manoeuvring a plurality of flaps, having mechanical way including a drive wheel, supporting, in a raised position, a circular locking disc with a diameter smaller than and the same axis of rotation as the drive wheel, and also including a plurality of rockers, and connected by mechanical transmission way to one or more flaps, the rockers including at least two semicircular cutouts having a radius equal to the radius of the locking disc and which are arranged such that, when a rocker is placed in one position, the centre of a semicircular cutout is disposed on the main axis such that the locking disc engages with the semicircular cutout and locks the rocker in the position.

Abstract: A device for manoeuvring an aerodynamic flap arranged on a motor vehicle, characterised in that it includes mechanical ways for shifting the flap from a retracted position to a deployed position, successively performing a movement extending the flap while keeping the plane of the flap parallel to the direction of an air stream flowing around the flap when the vehicle is moving, such that the aerodynamic pressure exerted on the flap is substantially zero, and then a movement pivoting the flap about a pivot axis located in a plane of the flap and passing substantially through a centre of aerodynamic thrust of the flap, such that the torque applied to the pivot axis and resulting from the aerodynamic forces is substantially zero. The shift from a deployed position to a retracted position is carried out by performing said movements in reverse order.

Abstract: A Motor vehicle wheel arch has a body of thermoplastic material with an opening and a mat closing the opening and fixed to the body by strips of thermoplastic material. A method of making the arch includes injecting the strips onto the mat and allowing them to solidify in contact therewith. An edge is formed on a reduced thickness portion of the strip. In cross-section, the edge thickness relates to the edge width l by a mathematical function f such that: ? 0 ? ? f ? ( x ) ? ? ? ? x ? h 2 where h is the height of the edge at its junction with the strip.

Abstract: The invention provides a sound-insulating part for a motor vehicle having an engine compartment and, beside the engine compartment, a clearance volume for accommodating vertical travel of a wheel of the vehicle, the part being characterized by the fact that it is arranged to form a sound screen between said engine compartment and said volume.
