Abstract
Abstract A ventilator grill for a motor vehicle interior comprises a front plate fixed to a fascia panel parallel rear plate movable relative thereto and connected to a ventilation hose. The front and rear plates define two arrays of apertures and are spaced apart by a set of tubes, the ends of which are pivotable in the apertures. The back plate may be moved by a control knob projecting through an aperture in the front plate so that the direction of the air stream from the grill can be varied.
