Abstract: A comfort system is provided for a motor vehicle. A seat occupancy sensor determines whether a third row zone is occupied. At least one flow controller is provided in the floor duct for controllably supplying the conditioned airflow to at least the third row outlet. If the third row zone is occupied, then a second row outlet and the third row outlet are turned on to supply a conditioned airflow to a front seat zone, a second row zone, and the third row zone. If the third row zone is not occupied, then the third row outlet is closed off. If the second row zone is not occupied, then the second and third row outlets are closed off. If occupied, then the second row outlet is turned on until a desired comfort level is achieved in the second row zone.

Abstract: An air duct for an automotive vehicle is blow molded with an elongated, hollow structural member to be used as a portion of a body of the vehicle. The structural member has an inner wall defining an elongated cavity communicating with first and second access holes at respective longitudinal positions along the structural member. A parison comprised of a thermally insulating material is inserted into the internal cavity. A source of inflation gas is connected to a mouth portion or the parison. The parison is heated and inflated within the internal cavity to an expanded shape to form the air duct disposed against the inner wall and spanning the first and second access holes. The air duct at one of the access holes is configured as an air inlet. The air duct at the other one of the access holes is configured as an air outlet.
