ABSTRACT:
An air extraction valve and grill assembly for mounting in an opening in the bodywork of the passenger compartment of a vehicle body, and for enabling the extraction of stale air from the passenger compartment, is molded from the rigid thermoplastic material and defines two air extraction apertures. Each aperture is controllably closed off by a valve flap. Each valve flap is molded from rigid thermoplastics material, or produced from other similar rigid material. Onto each valve flap are over-molded two strips of thermoplastic material. One of these strips forms a hinge for supporting the valve flap in the aperture and biassing it into a position where the other over-molded strip acts as a seal with the rigid body of the assembly.
