Towed vehicle air guide member - comprises panel sloping downwards with side vanes extending rearwards at acute angle to panel

摘要

The air guide member for a towed vehicle is particularly for a caravan. It comprises a plate (4) sloping downwards from its top edge near the top of the vehicle, together with a pair of vanes (5) joining onto the panel sides and extending rearwards. The vanes can be at an acute angle to the panel, whose width can reduce gradually from its top edge, where it is roughly of the same width as the vehicle superstructure. Its width at the lower end can be roughly 0.6 times that at the top end, and the vanes can be triangular, with their apices near the panel top edge.
