A vehicle comprises a passenger cabin ventilation system. The system includes a vent (310, figure 3), a duct 320 to supply an airflow to the vent, and a cover 340. A blower (220, figure 1) may be included. The duct extends along a sill 58 of a vehicle door and the cover encases the duct. Ideally the duct has a plurality of bores 325 that extend across an airflow passage of the duct and include respective aerofoil-shaped surrounding sidewalls 322 to seal the bores from the airflow passage. The cover may include a corresponding plurality of legs 341 that pass through the bores to provide a load path from the cover to the sill independent of the duct, thereby providing rigid and robust protection for the duct. Fixings (e.g. screws or rivets) can extend through the legs to secure the cover to the sill. A first inner side wall 345 and a second outer side wall 346 of the cover may pass on either side of the duct to provide additional load paths to the sill. The duct may be resiliently compressible.
