An air flow diverter for a vehicle having a front roof portion (3) and a rear roof portion (9) at a higher level than the front roof portion has superimposed laminar elements (5, 6), the lowermost of which is adjacent the front roof portion (3) of the vehicle. The or each other laminar element has its front edge disposed in proximity to the laminar element below it, defining therewith a transverse entrance slit (7). Each pair of adjacent laminar elements furthermore define a divergent duct downstream of the respective entrance slit. In operation of the vehicle a part of the air flow passes through the divergent duct, increasing in pressure, to establish a high pressure region downstream of the diverter, substantially fixed relative to the vehicle, which encourages the deflection of the principal part of the air flow over the roof and sides of the vehicle when the vehicle is in motion. <IMAGE> |
