A crossbar clamp actuator of a crossbar-to-vehicle coupler may include a horizontally traveling wedge block having a ramped, downward-facing first slide surface, and a wedge follower having a second slide surface in frictional contact with the first slide surface of the traveling wedge block. Substantially horizontal repositioning of the traveling wedge block may cause the ramped first slide surface to urge the wedge follower downward, thereby actuating a crossbar clamp.

A rack for carrying cargo on top of a vehicle that may include a crossbar and a pair of coupler assemblies for connecting opposing ends of the crossbar to raised rails on top of the vehicle. Each coupler assembly may include a body, a securing assembly to secure the body to the raised roof rail, and a crossbar clamp, where the securing assembly and the crossbar clamp are independently adjustable.

According to several aspects, a roof rail system for a vehicle includes a stanchion connected to a roof surface of a motor vehicle at a vehicle attachment portion and connected to a roof rail at a roof rail attachment portion. The stanchion has an outer surface, an inner surface, a leading and a trailing surface. The inner surface has a recessed portion, and an inlet hole and an outlet hole for receiving a load securing member. The stanchion is aerodynamically optimized to improve drag and wind-noise characteristics.

A roof rail system for a vehicle includes a stanchion extending away from the vehicle surface. The stanchion has an exterior surface connected to leading and trailing surfaces, and an inboard surface spaced apart from the outboard surface and connected to the leading and trailing surfaces. The leading surface faces forward, the trailing surface faces rearward, the outboard surface faces outward and the inboard surface faces inward. The stanchion has a cargo attachment feature having a first and second opening connected by a first passage. One of the outboard surface and the leading surface defines the first opening, and one of the inboard surface and the trailing surface defines the second opening. A plug is disposed within the first passage and defines a second passage extending from a first flexible aperture at an outer portion of the plug to a second flexible aperture at an inner portion of the plug.

A load carrier and a method for operating the load carrier. The load carrier includes a base, a lid, and a lock arrangement arranged on the base and/or the lid, to lock the lid to the base. The lock arrangement includes at least a first and a second displaceable lock element operable between a locked position and an unlocked position. The first and the second lock elements are arranged to respectively engage with a first and a second lock member arranged on the opposing base or lid when being positioned in the locked position. The lock arrangement further includes an elongated actuation element in working cooperation with the first and the second lock element. An actuator arranged to displace the elongated actuation element from a locked position to a first position and thereby displacing the first and the second lock element from the locked position to the unlocked position.

A semi-trailer aerodynamic drag deflection assembly for reducing aerodynamic drag upon all surfaces of the semi-trailer includes a pair of interior walls positioned against a respective one of a pair of lateral surfaces of a semi-trailer. A plurality of vents is positioned from an inner surface to an outer surface of the interior wall. A pair of exterior walls is positioned against a respective one of the pair of interior walls. An outside surface of each of the exterior walls has a plurality of indents for deflecting wind An undercarriage has a pair of side walls with a storage being positioned between each of the side walls. Each of the side walls has a plurality of fins directing aerodynamic drag from the bottom surface of the semi-trailer into each of the vents of each of the interior walls. A pair of doors provides access to the storage of the undercarriage.
