Ventilation for drivers of buses and heavy goods vehicles

摘要

The main application P 3543125.3 describes a ventilation system for the work area of drivers of buses and heavy goods vehicles. An air-nozzle arrangement is provided which is designed as laminar fan assembly to feed fresh air to the nose and mouth region of the driver at low velocity without the occurrence of draughts. To be able to feed clean air to the driver without lateral displacement of the airflow, and with low air rates and a comparatively small filter, it is proposed according to the invention that the intake nozzle for the recirculating air ventilation is arranged approximately in the shoulder region of the driver, the air, after flowing through the filter (6) being directed into laminar flow elements (3, 4) which are arranged, preferably pivotably, at the head or side of the driver. An adjustable, transparent blind (5) forms a barrier against side air from the entrance door at the right hand side of the driver. <IMAGE>
