Aerodynamic mud flap

A motor vehicle mud flap for attachment behind a wheel of a motor vehicle, the mud flap comprising:

• a plate-like integral body having an obverse and a reverse face, a suspension section, a quadrant section, and, optionally, an extension section in a longitudinal alignment;
• the suspension section configured for attachment to a mud flap bracket for suspension of the mud flap therefrom and;
• the quadrant section having an array of elongate through-openings positioned at an acute angle to a longitudinal axis of the mud flap;
• and
• the optional extension section having an array of elongate through-openings;
• wherein the array of elongate through-openings in the obverse face is defined by alternating elongate through-openings and ribs in parallel disposition;
• wherein the elongate through-openings are configured so that water and air can flow through the elongate through-openings, and debris larger than the width of the elongate through-openings is deflected by the mud flap;
• and
• wherein the obverse face and the reverse face have symmetry about a parallel plane between them as to at least the array of elongate through-openings and ribs in parallel disposition.

• and
• wherein the obverse face or a reverse face has a projecting rib and the other of the obverse and reverse faces has a recess corresponding to the rib, whereby multiple mud flaps can be stacked with ribs of one mud flap received in a corresponding recess in an overlying mud flap to reduce sliding of stacked mud flaps with respect to each other.
