Abstract:
1. An HVAC duct system of a vehicle comprising: an air duct for providing a passageway for forced conditioned air, the air duct having a first imaginary axis extending substantially parallel with the passageway; an air duct register coupled to the air duct for discharging forced air within the air duct to an interior of the vehicle, an opening of the air duct register defining an imaginary plane, the register having a second imaginary axis extending perpendicular to the imaginary plane of the register, the register including a plurality of vane-like members for selectively directing the flow of air as it exits the register, wherein the first and second imaginary axes are non-parallel; and an air flow straightener disposed within the air duct and juxtaposed to the register, the air flow straightener including a plurality of air guide members, wherein each air guide member includes a first end section aligned with the first imaginary axis and a second end section aligned with the second imaginary axis, wherein each air guide member receives the forced air flowing through the air duct in a direction substantially parallel with the first imaginary axis and redirects the forced air in a direction substantially parallel with the second imaginary axis for producing a substantially laminar flow of conditioned air as the forced air passes the vanes resulting in a reduction of noise; wherein the second end section of the air flow straightener includes a plurality of integrally formed clips for attachment and detachment to the register, and wherein the first end section of the air flow straightener disposed within the air duct is free floating.
