Abstract: Disclosed is a busbar spacer comprising a first busbar passage liner having a first spacer passage therethrough. The first busbar passage liner is arranged to be provided within a first busbar passage through a first busbar, to thereby electrically insulate from a wall of the first busbar passage a shank of a connector. The shank of the connector is arranged to pass through the first busbar passage liner to secure the first busbar to a mounting point.

Abstract: Disclosed is a framework member comprising a top-hat portion and a return portion, where the top-hat portion comprises an open brim wall, an open side wall extending from the open brim wall, a crown wall extending from the open side wall, a closed side wall extending from the crown wall and a closed brim wall extending from the closed side wall. The return portion comprises a return wall extending from the closed brim wall. The open brim wall, the open side wall, the crown wall, the closed side wall and the closed brim wall form, in cross-section, a top-hat shape and the closed side wall, the closed brim wall and the return wall form, in cross-section, a channel.

Abstract: A vehicle airflow control apparatus (900) has an air inlet (902) at the rear quarter glass (906) of the vehicle and ducting (908) leading via an openable joint (912) and rear ducting (912) past a bend (916) to an exit blowing aperture (918), a concertina element (928) allowing duct movement, the openable joint having a self-alignment cup (938) with wedging inner sides (944, 946), an interface seal connecting the rear ducting and the cup, a deployable spoiler (920) having a drive system (978), 10 outboard positional control of the spoiler being provided by a rod (998) with cone surfaces (1000, 1002).
