Cross car duct with integrated mode doors and HVAC module

摘要

A cross car duct for use in an instrument panel assembly of an automotive vehicle includes an upper beam of one piece molded plastic extending longitudinally between opposing A-pillars of the vehicle. The cross car duct also includes a lower beam of one piece molded plastic attached to the upper beam and extending longitudinally between the A-pillars. A magnesium steering column support for supporting conventional steering components on the cross car duct is fixedly secured to the upper beam. The upper beam includes a plurality of air ducts and the lower beam includes a plurality of air openings aligned with the air ducts for passing air through the beams. The lower beam also includes a housing for supporting an HVAC module. The cross car duct further includes a plurality of integrated mode doors and actuators operatively connected to the housing of the lower beam for actuation between an open position spaced from the air openings and a closed position covering the air openings in the lower beam. The HVAC module includes a lower casing integrated with the housing of the lower beam for supporting and enclosing the mode doors and the components of the HVAC module in the lower beam forming a cross car duct with integrated mode doors and an integral HVAC module.
