<p>The vehicle cab (4) has a roof structure (6), an upright cab front section (7) and two side walls (8) each defining a side envelope wall extending substantially vertically. The cab incorporates at least one convergent nozzle (33) located at a front upper corner of the cab, said nozzle comprising an inner wall (20) protruding inwardly with respect to the cab side envelope wall and an outer wall substantially level with said side envelope wall so as to channel the air flow from the upright cab front section to a cab side wall at a higher velocity.</p> |
