To improve the appearance of a tailgate provided with a rear spoiler, a tailgate of a vehicle includes a tailgate main body having a rear window opening a rear spoiler extending rearward from a part of the tailgate main body above the rear window opening a rear window panel that is mounted on an outer peripheral portion of the rear window opening of an outer surface of the tailgate main body and closes the rear window opening and a plate-shaped shield member mounted on a lower surface of the rear spoiler so as to shield a space formed between the lower surface of the rear spoiler and an upper end portion of the rear window panel.

An aerodynamic device provided as a plate-shaped body attached to a roof or a side wall of a vehicle includes means configured to selectively raise ribs arranged in two directions from a surface portion of the plate-shaped body in a switching manner between the two directions.

Various embodiments of an airfoil and machines with airfoils are disclosed. The airfoils include a thicker leading airfoil portion and a thinner trailing airfoil portion. In one embodiment, the leading airfoil portion is formed by bending a body of the airfoil back toward itself. In another embodiment, the leading airfoil portion has a solid geometry and includes two elliptic surfaces. To prevent detachment of airflow, the leading airfoil portion includes at least two arc portions or surfaces that act to direct the airflow down to the trailing airfoil portion in a manner that stabilizes vortexes that may form in the region of changing thickness.

A powered deployable spoiler assembly includes a support member adapted for mounting to a motor vehicle and a spoiler panel disposed in a recessed segment of the support member. A pair of power-operated drive units interconnect the spoiler panel to the support member and are operable to move the spoiler panel between a non-deployed position, a first deployed position to provide aerodynamic assistance at a first vehicle speed, and a second deployed position to provide augmented aerodynamic assistance at a second higher vehicle speed. Each drive unit defines a guide slot and includes a stanchion fixed to the spoiler panel and a follower assembly fixed to the stanchion and disposed for movement within the guide slot. Electric motors are coupled to rotary-to-linear conversion mechanisms for converting rotation into translation of the follower assemblies to control movement of the spoiler panel.

A multi-airfoil element wing includes a central single-airfoil element and an outer dual-airfoil element positioned outboard of each side of the central single-airfoil element. The single-piece member defines aerodynamic surfaces of the central airfoil element and both of the outer dual-airfoil elements. The single-piece member includes a carbon fiber resin hollow body forming at least a portion of the central single-airfoil element and of both outer dual-airfoil elements.

An aerodynamic resistance reduction system for a vehicle is provided and includes a pair of vertical panels pivotally attached to a rear end adjacent to rear vertical edges of a vehicle, a first horizontal panel assembly pivotally attached to a top end to each of the pair of vertical panels and pivotally attached to the rear end adjacent to a top horizontal edge of the vehicle, and a second horizontal panel assembly pivotally attached adjacent to an inside surface of each of the pair of side panels, the second horizontal panel assembly being disposed between the first horizontal panel assembly and a lower edge of the rear end of the vehicle.

A car having: a passenger compartment; a body surrounding the passenger compartment and having: a roof, a tail provided with a rear bumper, and a joining portion connecting the roof to the tail; a rear spoiler, which is arranged at the end of the joining portion in the area of the tail; and a deflector panel, which is arranged on the joining portion, is directly hit by an air flow brushing the joining portion during the travel and is mounted in a movable manner so as to move between a rest position, in which the deflector panel rests on the joining portion, and an active position, in which the deflector panel is lifted and spaced apart from the joining portion.

A drive arrangement for adjusting a flap of a motor vehicle about a body including a motor, a drivetrain, and a freewheel mechanism. The drivetrain is disposed between the motor and the flap. The freewheel mechanism provided with a drive component including a transmitting element, and a driven component provided with a receiving element coupled to the transmitting element. During motoric movement of the flap between the closed and the open position over at least a portion of the pivot angle, the motor actuates the drive component and displaces the transmitting element, from a neutral position, conjointly with the receiving element along a displacement path.

A rear spoiler of a motor vehicle. The spoiler includes a first part intended for being attached to the rear of the vehicle in an attachment position by a first attachment means, and a second part which is intended for being removably attached to the first part in an attachment position by a second attachment means, the second part leaving a portion of the upper surface of the first part visible in this attachment position.

A wing assembly for a vehicle includes a pivotable elongate wing member. The wing member extends from a first end to a second end, and is configured to pivot relative to a pivot axis between a first position and a second position. The pivot axis extends from the first end to the second end. The wing assembly further includes a first endplate pivotably coupled to the first end and a second endplate pivotably coupled to the second end. The first endplate has a first endplate position relative to the pivot axis, and is configured to maintain the first endplate position independent of wing member position. The second endplate has a second endplate position relative to the pivot axis, and is configured to maintain the second endplate position independent of wing member position.
